Definitions

  • the invention relates to apparatus and methods for distributing a pressure differential between an interior volume and an exterior volume.
  • a pressure differential distribution system for capturing or transporting substances from a first zone to a second zone.
  • Movement of objects or substances on a pressure gradient along at least one path from a first zone to a second zone encompasses technology such as pneumatic tube systems, vacuum cleaning systems, emission removal systems, ventilation systems, fluid distribution systems, or the like.
  • a significant problem with existing pressure differential distribution devices may be that they are large or take up a lot of space. Since space in any facility is finite, it follows that different mechanical, structural, or electrical items may compete for space. The larger the pressure differential distribution device the less space that can be reserved for other uses. The large size of current devices also presents a problem for installers. If installed prior to other mechanical or electrical fixtures, a large pressure differential distribution device may present an obstacle to the installation of subsequent mechanical or electrical fixtures; on the other hand, if the emission extraction system is to be installed after other fixtures are in place, a large system may not fit as easily as a smaller one. Additionally, large devices increase shipping costs inherent in transporting a heavier item. Examples of existing large pressure differential distribution devices are disclosed by Harvey Inc., Carbon Monoxide Exhaust Removal System.
  • Another significant problem with existing pressure differential distribution devices may be that the various components of the device, even when in the stored position, are visually or mechanically exposed.
  • having the components open to various types of physical mistreatment for example, being inadvertently hit or run into
  • other environmental abuses for example, chemical spills or spatters, or abrasives from various procedures
  • the visual appearance not only may the components of the device lack pleasing aesthetics for the consumer who may purchase the device (or not if the appearance is too awkward), but also to the public to which the device may connote an unattractive image. See for example, exposed components of devices disclosed by Harvey Inc., Carbon Monoxide Exhaust Removal System.
  • Another significant problem with existing pressure differential distribution devices may be that they utilize an exhaust hose that features a corrugated configuration.
  • This corrugation greatly diminishes the pressure differential generator's or exhaust fan's capacity to draw substances or emissions through the corrugated hose.
  • the corrugation creates resistance to gas flow, thereby requiring more powerful pressure differential generator.
  • a more powerful pressure differential generator may produce a greater amount of noise, yet another irritant to those who are in close proximity to the system.
  • Examples of corrugated hose are disclosure by Harvey Inc., Carbon Monoxide Exhaust Removal System. Harvey Hose and Tubing, Part H-40-20-AF or H-50-12-AF, p.
  • This method of retrieval may be disclosed, for example, by Tykron, Inc., Swing Arm with Hose and Balancer, p. 1, hereby incorporated by reference. If the hose is released prematurely by the operator, the hose or adapter may sling toward an unsuspecting fellow worker, or may cause damage to any object in its trajectory, due to the fact that the hoisting mechanism may be under high-torque spring tension. This hazard is particularly serious when the adapter is constructed of metal or has protruding elements. According to a disclosure by Aero-Motive Company, Balancer Series 10F, 15F, 10FLR & 15 FLR, pp.
  • Hose reels are often fastened to the walls, ceiling, or fixtures of a facility and can be completely immobile. Use of the system is often confined to a radius equal to the hose length. In-floor devices are completely immobile and, once again, the length of the exhaust hose may be the limit of the area in which an in-floor system may be used. See for example, Carmon Products, Inc., Carmon RotoBoom, Rotoboom Drawing No. 79D5; and Ammerman, Inc., Underfloor Automotive Exhaust Systems, p. 2, each of which is hereby incorporated by reference.
  • Another significant problem with existing pressure differential distribution devices may be that they must be mounted with great precision or with significant structural attachment considerations, due to the larger weight of the devices. Examples are disclosed by Monoxivent Systems Inc., Technical Information. Monoxivent Overhead Systems, p. 4; Nederman Inc., Overhead Exhaust Extractor. Single and Double Extractor Fans, Drawing No. 13-2, p. 2; and Tykron, Inc., Swing Arm with Hose and Balancer, p. 1, each of which is hereby incorporated by reference. Another significant problem with existing pressure differential distribution devices may be that the hoses hang in the way of persons.
  • Serpentine-type devices may provide better coverage than a hose reel type device or in-floor systems, but they can be unattractive and intrusive within the facility, because their hose frequently hangs in the way of the workers. See for example, Nederman Inc., Overhead Exhaust Extractor. Single and Double Extractor Fans, Drawing No. 13-2, p.2, hereby incorporated by reference. See also, United States Patent Nos. 5,679,072; 5,791,980; 6,012,978; and 5,362,273, each of which is hereby incorporated by reference, as examples of "hanging hoses".
  • Another significant problem with existing pressure differential distribution devices which are of the in-floor type may be that they do not completely retract into the floor receptacle or the floor covers may be left open. Persons working around such in-floor devices or open floor receptacles may suffer injury by tripping, or stumbling over strewn components of the emission extraction system, or suffer injury by falling into the open receptacle into which the hose enters. Moreover, the hose outlet assembly, even when operating properly with the floor receptacle closed, may often protrude above the floor surface, presenting similar hazard for those persons working around the device. See for example, Cesco-Advanced Air, Sales Brochure. Underfloor Disappearing with Vitrified Clay Pipe, Drawing No.

  • Yet another problem with existing pressure differential distribution devices may be that when multiple pressure differential distribution devices are connected to a common exhaust fan all draw or expel even when only one device may be in operation. Since many existing devices or the terminal adaptors on such devices are not equipped with a damper or closure, those devices not attached to a source of the substance to be moved will instead draw in the ambient air within the facility and move it external to the facility, or may alternately move air from external to the facility and expel it into the facility. This situation may be problematic because users of a facility may spend larger sums of money to heat or cool the ambient air within their facility. Examples of undampered or non-closured devices are disclosed by Monoxivent Systems Inc., Technical information Sheet. Vehicle Exhaust Damper, Series TCA, p.
  • existing terminal interfaces are constructed of metal which may scratch, dent, or otherwise damage the equipment to which they are attached.

Nozzles for Trucks and Other Commercial Vehicles, p. 2, each of which is hereby incorporated by reference.
  • Another significant problem with existing pressure differential distribution devices may be premature hose failure due to high temperatures on the hose about the point of attachment to the substance or emission source. This problem can be exacerbated by restrictions that may develop in the hose at the point where it is attached to the emission port, due to the bend radius that may be required for attachment. When the hose is continually restricted, hot spots may develop on the hose which may shorten the life of the hose.
