Description

Domaine TechniqueTechnical area

L'invention concerne un dispositif destiné à prélever des composants sphériques de tailles identiques, contenus dans un récipient à col cylindrique et à embouchure circulaire, et dont la principale application est la distribution et le comptage de petits granules d'usage médical, et plus précisément de granules homéopathique.The invention relates to a device for removing spherical components of identical sizes, contained in a container with a cylindrical neck and a circular mouth, the main application of which is the distribution and counting of small granules for medical use, and more precisely homeopathic granules.

Techniques antérieuresPrevious techniques

Dans le document FR-A-2 492 777, on a proposé un dispositif distributeur de granules comportant un bouchon présentant un évidement qui fait office de sas, ce dit bouchon étant traversé par un axe reliant deux disques mobiles chacun muni d'une lumière. Lors de la rotation du disque extérieur, on vient mettre en communication l'intérieur du tube avec le sas via la lumière placée sur le disque intérieur. Les granules s'accumulent dans le sas, puis lors d'une rotation supplémentaire, on met en communication ce sas et l'espace extérieur du tube, ce qui permet la distribution du nombre de granules qu'on peut stocker dans le sas.In document FR-A-2 492 777, a granule dispensing device has been proposed comprising a plug having a recess which acts as an airlock, said plug being crossed by an axis connecting two movable discs each provided with a light. During the rotation of the outer disc, the interior of the tube is brought into communication with the airlock via the light placed on the inner disc. The granules accumulate in the airlock, then during an additional rotation, this airlock is placed in communication with the outside space of the tube, which allows the distribution of the number of granules that can be stored in the airlock.

Un tel dispositif ne permet pas l'alimentation de granules à l'unité. En outre, tous le corps distributeur est à l'intérieur du tube, ce qui diminue le volume résiduel pour les granules.Such a device does not allow the feeding of granules per unit. In addition, all the dispensing body is inside the tube, which decreases the residual volume for the granules.

Dans le document FR-A-2 625 982, qui correspond au préambule, on a décrit un distributeur de granules avec un bouchon récéptacle s'adaptant sur l'embouchure du récipient et présentant des moyens d'entraînement en rotation du corps distributeur. Le distributeur est composé d'un socle fixé sur le goulot du tube et traversé par au moins une ouverture et dont la partie centrale est traversée par un axe tournant librement, reliant deux pièces situées de part et d'autre du socle. La pièce placée à l'intérieur du tube est composée de plusieurs bras radiaux entre chacun desquels est défini un logement susceptible de recevoir un granule. La deuxième pièce placée à l'extérieur du socle est un disque percé d'une lumière destinée à venir en regard de l'ouverture du socle faisant office de sas. Tout comme la première réalisation, le corps distributeur se trouve en grande partie enfoncé à l'intérieur du tube, ce qui réduit le volume restant disponible pour les granules. En outre, les pièces proposées pour réaliser cet ensemble distributeur sont de forme complexe, donc très difficiles à réaliser par moulage. Enfin et surtout, l'ensemble proposé ne présente pas de symétrie, ce qui augmente les difficultés pour automatiser la mise en place de ce dispositif en bout de tube.In document FR-A-2 625 982, which corresponds to the preamble, a granule dispenser has been described with a receptacle stopper fitting onto the mouth of the container and having means for driving the dispenser body in rotation. The distributor is composed of a base fixed on the neck of the tube and crossed by at least one opening and the central part of which is crossed by a freely rotating axis, connecting two parts located on either side of the base. The part placed inside the tube is composed of several radial arms between each of which is defined a housing capable of receiving a granule. The second part placed outside the base is a disc pierced with a light intended to come opposite the opening of the base acting as an airlock. Like the first embodiment, the distributor body is largely inserted inside the tube, which reduces the remaining volume available for the granules. In addition, the parts proposed to make this dispenser assembly are of complex shape, therefore very difficult to produce by molding. Last but not least, the proposed assembly has no symmetry, which increases the difficulties in automating the positioning of this device at the end of the tube.

Description sommaire de l'InventionBrief description of the invention

L'invention pallie ces inconvénients, c'est-à-dire qu'elle propose un dispositif de forme simple et facile à mouler, et présentant une symétrie rendant facile l'automatisation de sa mise en place.The invention overcomes these drawbacks, that is to say that it provides a device of simple shape and easy to mold, and having a symmetry making it easy to automate its implementation.

L'invention concerne un dispositif pour le prélèvement de produits sphériques de mêmes dimensions, tels que des globules ou des granules, contenus dans un récipient présentant un col cylindrique et une embouchure circulaire, du type comprenant:

  • . un corps distributeur de produits constitué de deux parties cylindriques parallèles, respectivement une première et une deuxième partie, reliées à leur centre par un axe, ladite partie cylindrique présentant des encoches destinées à recevoir un produit, lesdites encoches étant décalées d'une partie à l'autre, de manière qu'une section pleine d'une partie corresponde à une encoche de l'autre partie;
  • . une rondelle cylindrique présentant une fente radiale reliée à un perçage axial, destinée à venir coopérer avec l'axe, et au moins un évidement axial pour permettre le passage des produits de la première à la deuxième partie, ladite rondelle ayant un diamètre légèrement supérieur au diamètre interne du col du récipient pour permettre un emmanchement à l'extrémité circulaire du récipient;
  • . un bouchon réceptacle s'adaptatant sur l'embouchure circulaire du récipient et présentant des moyens d'entraînement en rotation du corps distributeur,
caractérisé:
  • en ce que la première et la deuxième partie sont identiques ;
  • et en ce que la première partie, la deuxième partie et la rondelle ont une épaisseur légèrement supérieure au diamètre d'un produit.
The invention relates to a device for collecting spherical products of the same dimensions, such as globules or granules, contained in a container having a cylindrical neck and a circular mouth, of the type comprising:
  • . a product dispensing body consisting of two parallel cylindrical parts, respectively a first and a second part, connected at their center by an axis, said cylindrical part having notches intended to receive a product, said notches being offset from one part to the other 'other, so that a solid section of one part corresponds to a notch of the other part;
  • . a cylindrical washer having a radial slot connected to an axial bore, intended to cooperate with the axis, and at least one axial recess to allow the passage of the products from the first to the second part, said washer having a diameter slightly greater than the internal diameter of the container neck to allow fitting at the circular end of the container;
  • . a receptacle cap adapting to the circular mouth of the container and having means for driving the distributor body in rotation,
characterized :
  • in that the first part and the second part are identical;
  • and in that the first part, the second part and the washer have a thickness slightly greater than the diameter of a product.

Autrement dit, l'invention consiste à installer à l'extrémité du tube une rondelle présentant une ouverture apte à laisser passer un granule et un trou central apte à recevoir un axe. Cet axe relie deux pièces identiques en forme générale de disque comportant des encoches, les deux disques étant angulairement décalés de sorte que l'ouverture de la rondelle ne peut se trouver que d'un seul côté à la fois. Ainsi, le corps distributeur présente une symétrie lui permettant d'être installé sur la rondelle indifféremment dans les deux sens.In other words, the invention consists in installing at the end of the tube a washer having an opening capable of allowing a granule to pass and a central hole capable of receiving an axis. This axis connects two identical parts in the general shape of a disc having notches, the two discs being angularly offset so that the opening of the washer can only be on one side at a time. Thus, the distributor body has a symmetry allowing it to be installed on the washer in either direction.

Avantageusement, en pratique, la fente radiale de la rondelle se compose d'un perçage axial proprement dit, destiné à venir se clipser sur l'axe du corps distributeur, et la fente axiale proprement dite est évasée pour former l'évidement destiné à recevoir un produit, en forme de secteur de cylindre.Advantageously, in practice, the radial slot of the washer consists of an axial bore proper, intended to be clipped onto the axis of the distributor body, and the axial slot proper is flared to form the recess intended to receive a product, in the form of a cylinder sector.

Dans une forme de réalisation, la rondelle cylindrique prend appui dans le col sur des taquets ménagés à cet effet sur la face intérieur du col.In one embodiment, the cylindrical washer is supported in the neck on tabs formed for this purpose on the inside of the neck.

Dans une autre forme de réalisation, la rondelle cylindrique présente sur un de ses deux bords, une collerette d'appui sur l'embouchure circulaire du récipient.In another embodiment, the cylindrical washer has on one of its two edges, a support flange on the circular mouth of the container.

Avantageusement, pour assurer le bon écoulement des granules, les arêtes des encoches du corps distributeur et de la rondelle sont chanfreinées. De préférence, l'inclinaison du chanfrein des faces externes de chacune des deux parties du corps distributeur, est plus grande que celle du chanfrein interne. Cette géométrie rend l'écoulement reversible, c'est-à-dire du tube vers le réceptacle, ou du réceptacle vers le tube dans le cas où trop de granules ont été délivrés.Advantageously, to ensure good flow of the granules, the edges of the notches of the distributor body and of the washer are chamfered. Preferably, the inclination of the chamfer of the external faces of each of the two parts of the distributor body is greater than that of the internal chamfer. This geometry makes the flow reversible, that is to say from the tube to the receptacle, or from the receptacle to the tube in the case where too many granules have been delivered.

En ce qui concerne le dispositif d'entraînement, dans une variante, celui-ci est constitué par :

  • un pivot central, disposé à l'intérieur du bouchon réceptacle selon l'axe de symétrie du bouchon, ledit pivot présentant à son extrémité une empreinte d'entraînement ;
  • une empreinte complémentaire disposée au centre de la face extérieure de chacune des deux parties du corps distributeur.
As regards the drive device, in a variant, it consists of:
  • a central pivot, disposed inside the receptacle stopper along the axis of symmetry of the stopper, said pivot having at its end a drive imprint;
  • a complementary imprint disposed in the center of the outer face of each of the two parts of the dispenser body.

Dans une autre forme d'exécution du moyen d'entraînement, les secteurs pleins des deux parties du corps distributeur sont dotés d'au moins une dent d'entraînement située sur leur face externe aboutissant dans le réceptacle, le réceptacle étant pourvu sur sa cloison interne d'une couronne dentée située dans un plan parallèle aux faces du distributeur, pour assurer la rotation de celui-ci par engrenage avec les dents de sa face externe.In another embodiment of the drive means, the solid sectors of the two parts of the distributor body are provided with at least one drive tooth situated on their external face ending in the receptacle, the receptacle being provided on its partition internal of a ring gear located in a plane parallel to the faces of the distributor, to ensure the rotation of the latter by gear with the teeth of its external face.

Dans une forme préférée de réalisation, les encoches du corps distributeur sont constituées par trois secteurs radiaux régulièrement espacés. Cela permet la distribution de deux ou trois granules par tour du corps distributeur.In a preferred embodiment, the notches of the dispenser body are formed by three regularly spaced radial sectors. This allows the distribution of two or three granules per revolution of the distributor body.

Pour faciliter le comptage et la visualisation des granules distribués, le bouchon réceptacle est de préférence en matière plastique transparente, alors que le récipient contenant les granules est un tube cylindrique en matière plastique colorée pour protéger lesdits granules de la lumière.To facilitate counting and viewing the granules dispensed, the receptacle cap is preferably made of transparent plastic, while the container containing the granules is a cylindrical tube of colored plastic to protect said granules from light.

Manière de réaliser l'InventionWay of carrying out the Invention

Comme représenté aux figures 3 et 7, le dispositif distributeur de granules se compose essentiellement de trois parties, à savoir une rondelle (6) placée à l'embouchure du tube, un corps distributeur pivotant au centre du bouchon, et un réceptacle (11) apte à recevoir les granules.As shown in Figures 3 and 7, the granule dispensing device essentially consists of three parts, namely a washer (6) placed at the mouth of the tube, a dispensing body pivoting in the center of the cap, and a receptacle (11) suitable for receiving the granules.

Le corps distributeur de granules (1), tel que représenté à la figure 1, est constitué de deux parties cylindriques A et B qui sont symétriques par rapport à un axe (2) les reliant par le centre. Ces deux parties A et B sont identiques et chacune est constituée de secteurs de cylindres (3), concentriques, égaux entre eux, taillés verticalement dans l'épaisseur de ladite partie, et séparés les uns des autres par des ouvertures (4) égales entre elles et concentriques avec les secteurs de cylindres (3) dont les dimensions sont adaptées au diamètre des granules à prélever. Les deux parties A et B symétriques et en vis-à-vis par rapport à l'axe (2), sont décalées de telle façon qu'un secteur de cylindre plein (3) de la partie A correspond à un secteur de cylindre vide (4) de la partie B. Comme représenté à la figure 1, les secteurs pleins (3) et les secteurs vides (4), égaux entre eux, sont dans une version préférentielle au nombre de trois, permettant ainsi la distribution d'un granule à chaque tiers de tour du corps distributeur (1). Cette cadence de distribution est particulièrement bien adaptée pour le décompte des prescriptions classiques correspondant généralement à trois, voire cinq granules.The granule distributor body (1), as shown in FIG. 1, consists of two cylindrical parts A and B which are symmetrical with respect to an axis (2) connecting them through the center. These two parts A and B are identical and each consists of sectors of cylinders (3), concentric, equal to each other, cut vertically in the thickness of said part, and separated from each other by openings (4) equal between they and concentric with the cylinder sectors (3) whose dimensions are adapted to the diameter of the granules to be sampled. The two parts A and B symmetrical and opposite with respect to the axis (2), are offset so that a full cylinder sector (3) of part A corresponds to an empty cylinder sector (4) of part B. As shown in FIG. 1, the solid sectors (3) and the empty sectors (4), equal to each other, are in a preferred version three in number, thus allowing the distribution of a granule every third of a turn of the distributor body (1). This distribution rate is particularly well suited for counting conventional prescriptions generally corresponding to three or even five granules.

Les deux parties A et B sont d'un gabarit identique, ce qui permet indifféremment, dans un montage rapide, manuel ou automatique, de constituer l'une ou l'autre face du corps distributeur, ce qui évite toute perte de temps et élimine toute possibilité d'erreur.The two parts A and B are of an identical size, which allows indifferently, in a quick assembly, manual or automatic, to constitute one or the other face of the distributor body, which avoids any loss of time and eliminates any possibility of error.

La rondelle cylindrique (6) comporte un épaulement (9) périphérique extérieur qui agit sur l'embouchure du récipient de granules (10), comme représenté à la figure 3. L'épaisseur de cette rondelle (6) est légèrement supérieure au diamètre d'un granule à prélever. Cette rondelle (6) est traversée par un perçage axial (7) et un évidement axial (8). Le perçage axial (7), situé au centre de ladite rondelle (6), est d'un diamètre adéquat pour enserrer, d'un effort léger, l'axe (2) du corps distributeur (1). L'évidement (8) est légèrement sécant du perçage axial (7) et présente également une ouverture vers l'extérieur de la rondelle, de telle façon à permettre que la rondelle (6) puisse, grâce à l'ouverture constituée par le perçage (7) et l'évidement (8), d'une part venir se positionner sur l'axe (2) du corps distributeur (1), et d'autre part, permettre le passage d'un granule entre les parties A et B symétriques du corps distributeur (1) lorsque ces deux parties A,B et la rondelle (6) sont solidarisées et positionnées à l'horizontale sous le tube vertical (10) concernant les granules à prélever.The cylindrical washer (6) has an outer peripheral shoulder (9) which acts on the mouth of the container of granules (10), as shown in FIG. 3. The thickness of this washer (6) is slightly greater than the diameter d 'a granule to be sampled. This washer (6) is traversed by an axial bore (7) and an axial recess (8). The axial bore (7), located in the center of said washer (6), is of an adequate diameter to grip, with a light force, the axis (2) of the distributor body (1). The recess (8) is slightly secant from the axial bore (7) and also has an opening towards the outside of the washer, so as to allow the washer (6) to be able, thanks to the opening formed by the bore (7) and the recess (8), on the one hand come to be positioned on the axis (2) of the distributor body (1), and on the other hand, allow the passage of a granule between the parts A and B symmetrical to the distributor body (1) when these two parts A, B and the washer (6) are secured and positioned horizontally under the vertical tube (10) relating to the granules to be sampled.

Le réceptacle de granules (11), réalisé en matière transparente, a pour fonction principale de recevoir les granules lors de leur sortie du tube, et de permettre l'entraînement du corps distributeur (1).The main function of the granule receptacle (11), made of transparent material, is to receive the granules when they exit the tube, and to allow the dispensing body (1) to be driven.

A cet effet, et dans une variante représentée à la figure 4, ce réceptacle comporte une couronne dentée (12), située dans un plan parallèle à celui de l'embouchure du récipient de granules, intérieur au réceptacle solidarisé de celui-ci, et dont les dents sont dirigées vers le récipient de granules. Par ailleurs, sur chaque partie A,B du corps distributeur, au moins un des secteurs pleins (3) comporte une dent d'entraînement (5) s'engrenant avec celle de la couronne dentée (12) du réceptacle de granules. Cette couronne dentée a une épaisseur appropriée à celle des dents d'entraînement (5) du corps distributeur (1). Celui-ci s'inscrit dans un cylindre dont le diamètre générateur correspond approximativement au diamètre du cercle générateur du cylindre intérieur du réceptacle, pour des rotations en condition optimale. Les dents de la couronne sont identiques à celles du corps distributeur (1) pour un engrenage parfait en rotation.To this end, and in a variant shown in FIG. 4, this receptacle comprises a toothed crown (12), situated in a plane parallel to that of the mouth of the container of granules, inside the receptacle integral with the latter, and whose teeth are directed towards the container of granules. Furthermore, on each part A, B of the dispenser body, at least one of the solid sectors (3) has a drive tooth (5) meshing with that of the ring gear (12) of the granule receptacle. This ring gear has a thickness suitable for that of the drive teeth (5) of the distributor body (1). This fits into a cylinder whose generator diameter roughly corresponds to the diameter of the cylinder's generator circle. interior of the receptacle, for rotations in optimal condition. The teeth of the crown are identical to those of the distributor body (1) for a perfect rotating gear.

La figure 6 montre un autre moyen d'entraînement du corps distributeur par rotation du réceptacle, moyen dans lequel le noyau central (14) disposé au fond et à l'intérieur du réceptacle (11), comporte un embout (17) femelle de forme polyédrique qui vient coopérer avec un système d'entraînement complémentaire (16), situé au centre de la partie externe du corps distributeur pour entraîner ce dernier en rotation.FIG. 6 shows another means of driving the dispenser body by rotation of the receptacle, means in which the central core (14) disposed at the bottom and inside the receptacle (11), comprises a female end piece (17) polyhedral which cooperates with a complementary drive system (16), located in the center of the external part of the distributor body to drive the latter in rotation.

Dans la variante représentée en figure 7, le noyau central (14) reçoit un embout mâle cruciforme venant coopérer avec une empreinte complémentaire (16) ménagée sur le centre de la partie externe du corps distributeur.In the variant shown in Figure 7, the central core (14) receives a cruciform male end piece cooperating with a complementary cavity (16) formed on the center of the external part of the dispenser body.

Il va de soi que l'entraînement peut être réalisé par tout type d'embout, mâle ou femelle, interne ou externe, de type cruciforme polyédrique ou de tout autre type auto-centreur.It goes without saying that the drive can be carried out by any type of tip, male or female, internal or external, of the polyhedral cruciform type or of any other self-centering type.

Dans le but d'assurer un volume suffisant pour la réception des granules dans le réceptacle (11), il convient que la cote entre la base de la couronne dentée et le fond dudit réceptacle soit au moins équivalente ou de préférence légèrement supérieure au diamètre des granules à prélever.In order to ensure a sufficient volume for the reception of the granules in the receptacle (11), the dimension between the base of the ring gear and the bottom of said receptacle should be at least equivalent or preferably slightly greater than the diameter of the granules to be sampled.

L'utilisation d'un noyau central pour l'entraînement du corps distributeur, permet de maintenir une étanchéité entre l'intérieur du tube et l'extérieur lorsque le réceptacle est en position fermée. Cette étanchéité n'est pas assurée dans les dispositifs existants dans lesquels l'entraînement se fait par une couronne cannelée située en périphérie du corps distributeur et coopérant avec une couronne cannelée placée à l'intérieur du réceptacle.The use of a central core for the drive of the dispenser body makes it possible to maintain a seal between the inside of the tube and the outside when the receptacle is in the closed position. This sealing is not ensured in existing devices in which the drive is done by a fluted ring located on the periphery of the dispensing body and cooperating with a fluted ring placed inside the receptacle.

Le fonctionnement de ce distributeur de granules est illustré aux figures 9 à 14. Dans un premier temps, le tube est renversé de sorte que le réceptacle se trouve orienté vers le bas. Par gravitation, les granules (15) viennent se positionner dans tous les secteurs de cylindres (4) de la partie A du corps distributeur (1), comme représenté aux figures 9 et 12. Ensuite, comme on le voit aux figures 10 et 13, dès lors que l'un des secteurs de cylindres (4) de la partie A du corps distributeur (1) est en correspondance avec le passage des granules constitué par l'évidement (8) de la rondelle (6), un premier granule (15) descend par gravitation dans ledit passage et reste en attente sur la face supérieure d'un secteur plein de la partie B, alors qu'un deuxième granule vient se superposer sur le premier dans le secteur de cylindre vide (4) de la partie A du corps distributeur (1).The operation of this pellet dispenser is illustrated in Figures 9 to 14. First, the tube is inverted so that the receptacle is oriented downward. By gravitation, the granules (15) are positioned in all the cylinder sectors (4) of part A of the distributor body (1), as shown in Figures 9 and 12. Then, as seen in Figures 10 and 13 , as soon as one of the cylinder sectors (4) of part A of the distributor body (1) is in correspondence with the passage of the granules constituted by the recess (8) of the washer (6), a first granule (15) descends by gravitation in said passage and remains waiting on the upper face of a solid sector of part B, while a second granule is superimposed on the first in the empty cylinder sector (4) of the part A of the distributor body (1).

Après avoir tourné le réceptacle (11) d'un tiers de tour, le premier granule (15) tombe dans ledit réceptacle (11) alors que le deuxième est entraîné sur la rondelle (6) par l'un des deux secteurs de cylindres pleins (3) de la partie A du corps distributeur (1). Cette rotation ramène l'un des secteurs de cylindres pleins (3) de la partie A dans une position de fermeture du passage (8) de la rondelle (6) et l'un des secteurs de cylindres vides (4) de la partie B dans une position d'ouverture dudit passage (8), ce qui permet la descente du premier granule dans le réceptacle.After having turned the receptacle (11) by a third of a turn, the first granule (15) falls into said receptacle (11) while the second is entrained on the washer (6) by one of the two sectors of full cylinders (3) of part A of the distributor body (1). This rotation brings one of the sectors of full cylinders (3) of part A into a position for closing the passage (8) of the washer (6) and one of the sectors of empty cylinders (4) of part B in an open position of said passage (8), which allows the descent of the first granule into the receptacle.

A partir d'un corps distributeur (1) à trois secteurs de cylindres pleins sur chaque partie, on voit qu'à chaque rotation complète, il est distribué trois granules.From a distributor body (1) with three sectors of full cylinders on each part, it can be seen that with each complete rotation, three granules are distributed.

Pour encore améliorer la symétrie du système, on peut réaliser la rondelle (6) de manière symétrique. Dans ce cas, la rondelle (6) est introduite dans le col du tube jusqu'à prendre appui sur des taquets ménagés à l'intérieur de ce tube.To further improve the symmetry of the system, the washer (6) can be made symmetrically. In this case, the washer (6) is introduced into the neck of the tube until it rests on the tabs formed inside this tube.

La symétrie du corps de distribution permet avantageusement de faire circuler les granules du réceptacle vers l'intérieur du tube, dans le cas où, on a procédé par erreur à une distribution d'un nombre trop important de granules.The symmetry of the dispensing body advantageously makes it possible to circulate the granules from the receptacle towards the interior of the tube, in the event that an excessively large number of granules has been dispensed.

Il ressort clairement de la description qui précède que le dispositif de prélèvement selon l'invention présente de nombreux avantages particulièrement intéressants. D'une part, en terme de fonctionnement, le système permet d'assurer la maîtrise du nombre de granules distribués, tant en distribution qu'en récupération, ainsi que le maintien d'une étanchéité nécessaire pour la conservation optimale des granules. D'autre part, en ce qui concerne la fabrication et l'implantation du dispositif, la symétrie du corps distributeur permet une grande simplification des moules d'injection et également une facilité d'automatisation de l'opération de mise en place, ce qui se traduit par une baisse des investissements nécessaires, une augmentation du rendement et des cadences de fabrication.It is clear from the above description that the sampling device according to the invention has many particularly advantageous advantages. On the one hand, in terms of operation, the system makes it possible to control the number of granules distributed, both in distribution and in recovery, as well as maintaining the seal necessary for optimal conservation of the granules. On the other hand, with regard to the manufacture and implantation of the device, the symmetry of the dispensing body allows a great simplification of the injection molds and also an ease of automation of the positioning operation, which results in a reduction in the investments required, an increase in yield and production rates.
