Abstract: A counterweight cover for a compressor is provided and may include an annular body having a recess at least partially defined by an outer circumferential portion, an inner circumferential portion, and an upper portion connecting the outer circumferential portion and the inner circumferential portion. A suction baffle may be disposed on the annular body and may direct a flow of suction gas within the compressor.

Abstract: An improved napkin device is set forth. The device includes a front face adapted for opening to load napkins therein. A first downwardly angled steel rod is fixed to a first side face, and a second downwardly angled steel rod is fixed to a second side face. Each of the steel rods has a substantially circular cross section. A plate adapted to slide along the first and second steel rods until it reaches a stop, disposed perpendicular to the first and second side faces of the device is provided. The stop is connected to the first and second side faces. The plate comes to rest at the stop as it slides along the first and second steel rods.

Abstract: A napkin dispenser with a springless means for urging napkins therein toward an opening in the front face of the dispenser. The front face has two side edges with each side edge connected a side wall of the dispenser and each side wall has at least one inclined guide that is sloped downwardly toward the front face. The means for urging napkins comprises a generally vertical plate having at least one nub on each side edge, with each nub associated with an inclined guide of one of the side walls, so that the plate urges the napkins disposed in the structure to move toward the opening in the front face through which the napkins can be withdrawn from the napkin dispenser independent of a spring.

Abstract: A balancing system for different compressors utilizes a counterweight having a common exterior configuration. The mass of the counterweight is optimized for each compressor by changing the size of a recess located in the counterweight. In one embodiment, the recess is an arcuately shaped recess; and in another embodiment, the recess is a plurality of holes.

Abstract: Improved filtration media or filter bodies can be made from fine fiber and can be formed into a filtration structure having no internal defects. The filter media or filter body comprises a collection of spot in fiber with defined fiber diameter, layer thickness and media solidity. The fine fiber is formed into a media body and obtains substantial flux and filtration efficiency. The filtration media or body can comprise single or multiple layers of fine fiber combined into the improved filter body.

Abstract: An articulated surgical table configured to alternatively receive an orthopedic attachment and a scanning table attachment. The orthopedic attachment is provided with a frame having a plurality of mounting points for mounting two detachable spar members. Either or both of the spar members may be mounted to the frame to provide the desired level of patient support and operator access. In addition, a pelvic support plate is supported on top of the frame and is formed with an asymmetrical construction. The pelvic support plate includes a cutout area on a front corner thereof for permitting additional access to the affected or broken leg of a patient. The plate may be flipped over to position the cutout area on the opposite side of the patient, depending on the location of the affected leg.

Abstract: A shoulder arthroscopy attachment for use with a surgical table wherein the attachment may be attached to a seat section of the table in place of an articulated leg section. The attachment includes a lumbar support assembly for supporting the lumbar portion of a patient's back, and a headrest assembly including an upper back support and a headrest. The upper back support is adjustable in a lateral direction whereby either of a patient's shoulders may be exposed for an operation while supporting the opposite shoulder on the upper back support. The headrest is adjustable relative to a frame for the headrest assembly whereby the head of a patient may be accommodated at a variety of positions.

Abstract: A surgery table including a table top attachment providing for extreme angular positioning of a patient. The surgery table includes a base supporting a support column, and an articulated patient support portion pivotally attached to an upper end of the column. The table top attachment is attached to an articulated section of the table for movement with the articulated section whereby the attachment may be positioned at an extreme reverse Trendelenburg position. When the attachment is detached from the surgery table, the surgery table may be used in a conventional manner to position a patient in a plurality of articulated positions.

Abstract: An initiator, for use in a gas generator, includes an enclosed volume in communication with apertures for introducing liquid propellant and pre-pressurization gas into a propellant ignition chamber, and an aperture for introducing combusted gasses into a gas generator. A mechanism for controlling when the gases are allowed to enter the gas generator, and a heater/electrode to initiate combustion of the liquid propellant, also communicate with the enclosed volume. The propellant and the pre-pressurization gas may be introduced together or through separate ports. The heater/electrode thermally decomposes and vaporizes the propellant causing pressurization of the ignition chamber until a critical value is reached and the propellant ignites and burns. The burning propellant increases the chamber pressure beyond a predetermined value thereby opening the controlling mechanism and allowing the combusted gases to be introduced into the gas generator combustion chamber.

Abstract: A continuous flow-rate gas generator fueled by liquid mono-propellant includes a propellant storage tank, a motor-driven pump (or other pressurization technique) to force the propellant into a combustion chamber having an enclosed volume, an injector to effectively break up the incoming liquid propellant into droplets that facilitate ignition and sustain combustion, an igniter to initiate the combustion process, a nozzle to expand the exhaust gases in order to optimize the pressure and temperature of the working fluid, and exhaust ducting to direct the flow and handle the further heat transfer requirements. If desired, the output may be varied through two mechanisms: either by including an exit gas valve used to vary the exit gas flow to match delivery needs; or by having a plurality of continuous gas generators connected in parallel to a manifold assembly and relying on the combination of mixed flow-rates to match a required gas output.
