Description
Hydraulisk regnestav. Hydraulic slide rule.
Foreliggende oppfinnelse omhandler en regnestav som skiller seg fra de vanlig kjente rengestavef ved at den bevegelige delen, som vanligvis er utstyrt med logaritmiske skalaer, er erstattet av en væskesøyle hvis lengde og posisjon kan innstilles i forhold til en fast skala. The present invention relates to a calculating rod which differs from the commonly known measuring rods in that the moving part, which is usually equipped with logarithmic scales, is replaced by a liquid column whose length and position can be set in relation to a fixed scale.
Konstruksjonen av denne regnestav fremgår av fig. 1 og fig. 2. Fig. 1 fremstil-ler et snitt av fig. 2. Regnestaven er rek-tangulært utformet og fremstillet av et transparent material, for eksempel plast. Sylindriske beholdere, (1) og (2), er utformet i stavens begge ender. Disse beholdere er forbundet med en kanal (3) og inne-holder en farvet væske (4). Fleksible ski-ver (5) dekker beholdernes åpninger på undersiden av staven, mens de andre åp-ningene er dekket av en transparent plate (6). Skalaer er oppmerket på oversiden eller på undersiden av den gjennomsiktige plate The construction of this calculator can be seen in fig. 1 and fig. 2. Fig. 1 shows a section of fig. 2. The measuring stick is rectangular in shape and made of a transparent material, for example plastic. Cylindrical containers, (1) and (2), are formed at both ends of the rod. These containers are connected by a channel (3) and contain a colored liquid (4). Flexible discs (5) cover the containers' openings on the underside of the rod, while the other openings are covered by a transparent plate (6). Scales are marked on the top or bottom of the transparent plate
(6) langs kanalen (3) mellom de to beholdere. Den andre siden av regnestaven kan også være utstyrt med skalaer, f. eks. mellom den gjennomsiktige platen (7) og kanalen (3). Fremgangsmåten ved anvendelse av regnestaven er illustrert ved hjelp av fig. 3 og fig. 4. Ved å holde staven i en viss vinkel til horisontalplanet (se fig. 3) opp-når en at åpningen som fører inn til kanalen (3) er helt dekket av den farvede ves-ken (4). Når en presser på den elastiske platen (5) for beholderen (1), vil volumet i denne beholder minske og væsken vil trenge inn i kanalen (3). Etter at veskesøylen har nådd den ønskede lengde i forhold til skalaen, svinges staven over i den stillingen i forhold til horisontalplanet som er avbildet på fig. 4, hvorved væskesøylen brytes (6) along the channel (3) between the two containers. The other side of the ruler can also be equipped with scales, e.g. between the transparent plate (7) and the channel (3). The procedure for using the calculator is illustrated with the help of fig. 3 and fig. 4. By holding the rod at a certain angle to the horizontal plane (see fig. 3), you will find that the opening leading into the channel (3) is completely covered by the colored bag (4). When you press on the elastic plate (5) for the container (1), the volume in this container will decrease and the liquid will penetrate into the channel (3). After the bag column has reached the desired length in relation to the scale, the rod is swung over to the position in relation to the horizontal plane depicted in fig. 4, whereby the liquid column is broken
over en skarp egg (8). Idet staven svinges over fra den stilling som er avbildet i fig. above a sharp egg (8). As the rod is swung over from the position depicted in fig.
3 til den stilling som er avbildet i fig. 4 er 3 to the position depicted in fig. 4 is
trykket konstant i hele kanalen, hvilket vil resultere i at væskesøylen er stasjonær mens denne bevegelse pågår. Eggen (8) tjener først og fremst til å dele væskesøylen så nøyaktig som mulig ved delestreken 1,0 og dernest vil en relativ liten åpning over eggen (8) sammen med en relativ høy visko-sitet av væsken bevirke en viss dempning av væskesøylens bevegelse. Ved å presse ytter-ligere på den elastiske plate for beholderen (1), vil luften i beholderen trenge inn 1 kanalen (3) og føre væskesøylen til en the pressure is constant throughout the channel, which will result in the liquid column being stationary while this movement is in progress. The egg (8) primarily serves to divide the liquid column as accurately as possible at the dividing line 1.0 and secondly, a relatively small opening above the egg (8) together with a relatively high viscosity of the liquid will cause a certain damping of the movement of the liquid column . By pressing on the elastic plate for the container (1), the air in the container will penetrate the channel (3) and lead the liquid column to a
ønsket stilling i forhold til den faste skalaen. Skal man f. eks. multiplisere 3 med 2 presses først væskesøylen fra beholderen desired position in relation to the fixed scale. Should one e.g. multiply 3 by 2, the column of liquid is first pressed from the container
(1) inn i kanalen til merket 3 på den faste (1) into the channel to mark 3 on the fixed
skalaen ved at staven holdes i den stilling som fig. 3 angir. Deretter vendes staven til den stilling som er antydet i fig. 4. Luften presser så væskesøylen slik at dens nedre ende kommer like overfor delestreken 2 på skalaen. Svaret 6 kan så avleses ved væske-søylens øvre ende. Dette skjer ved at volumet av kanalen mellom delestreken 1 og 3 er like stort som volumet mellom delestreken 2 og 6. Generelt gjelder at volumet av kanalen mellom delestreken 1 og multi-plikand på skalaen er like stort som volumet mellom multiplikator og produkt. Hvis produktet er større enn 10, må beholderen (2) i fig. 1 brukes til innstilling av væske-søylen. Ved divisjon avleses svaret ved væs-kesøylens nedre ende. the scale by holding the rod in the position shown in fig. 3 indicates. The rod is then turned to the position indicated in fig. 4. The air then pushes the column of liquid so that its lower end comes just opposite dividing line 2 on the scale. The answer 6 can then be read at the upper end of the liquid column. This happens because the volume of the channel between the dividing line 1 and 3 is as large as the volume between the dividing line 2 and 6. In general, the volume of the channel between the dividing line 1 and the multiplicand on the scale is as large as the volume between the multiplier and the product. If the product is larger than 10, the container (2) in fig. 1 is used for setting the liquid column. When dividing, the answer is read at the lower end of the liquid column.
En av fordelene ved den hydrauliske regnestav er at avstanden mellom dele-strekene på skalaen kan være konstant, øke eller minske for enhver kontinuerlig, One of the advantages of the hydraulic slide rule is that the distance between the dividing lines on the scale can be constant, increase or decrease for any continuous,
