Abstract: Embodiments of this invention include pressure differential barrier members (10) for separating selected substances from fluid, gases and/or liquid, and methods of making the same. They include separation material (18) which, with respect to the fluid to be treated, is pervious and exhibits desired separation capabilities. They may also, at least in part, include material which is substantially impervious to the fluid. They include bridges (50) spanning flow paths to form lateral flow paths (15), and they may also include flow paths that are unabridged. All flow paths through such embodiments are either through structural elements which themselves have desired separation capabilities or are occupied by separation material (18) that is pervious to the fluid being treated and is of such desired characteristics.

Abstract: A variable displacement compressor which has a suction chamber,  a discharge chamber,  and a crank chamber.   The displacement of the compressor is controlled by supplying refrigerant to the crank chamber from the discharge chamber via a pressurizing passage and releasing the gas into the suction chamber via a pressure releasing passage.  An increase in the pressure in the crank chamber decreases the displacement, and a decrease in the pressure in the crank chamber increases the displacement.   A displacement controlling structure of the compressor includes an electromagnetic valve which alters the size of an area of the pressurizing passage.   A computer controls the electromagnetic valve in accordance with commands to alter the displacement.  The computer enlarges the opened area  of  the  pressurizing  passage  by  controlling  the electromagnetic valve in response to commands to reduce the displacement.

Abstract: . A thermal printer (10) for printing linerless labels is operated so that the pressure sensitive adhesive of the sec-ond face (14) of the labels does not stick to a drive roller (16) which advances and re-verses the labels, and coop-erates with the thermal print-head (17) to effect printing. A cutter (18) is disposed down-stream of the print head and drive roll from a linerless la-bel roll takeoff (12). Between the cutter and the drive roller is an air knife (35) which di-rects a substantially uniform flow of gas to the peripheral surface of the drive roller to prevent the adhesive of the la-bels from sticking to the drive roller peripheral surface. Air flow through the air knife is at a pressure of about 20-50 psi (preferably about 30 psi) and the air flow may be provided continuously or only during initiation and continuation of printing and advancing the printer. Operation of the driver roller is also controlled to prevent sticking by advancing the roll of linerless labels so that the leading edge is aligned with the cutter, completely formatting the printer while the leading edge is aligned with the cutter, reversing the label leading edge by operating the drive roll so that the leading edge moves to an initial position for printing of the leading label of the roll, and with a delay of less than 0.5 seconds (i.e. substantially immediately) initiating printing and advancing so that the adhesive does not have any opportunity to stick to the drive roller.

Abstract: An improved knife clamping system for use in an apparatus for processing wood, such as a flaker, chipper or waferizer, that employs a rotary disc or ring (2), cutting knives (10), holding locations (8) mounted on the disc or ring (2) to receive the cutting knives (10), clamping members (35) to engage and hold the cutting knives in position and fasteners (36) to mount the clamping members to the holding locations. The improvement comprises providing a surface (30, 40) having an undulating profile to engage against the cutting knives (10). The undulating surface can be formed on the clamping member (35), at the holding location (8) or at both locations. The surface is shaped to deform to engage the cutting knives (10) with a uniform clamping load upon securing of the fasteners (36) to a pre-selected torque. The foregoing arrangement requires fewer fasteners (36) while still maintaining an adequate clamping force on the cutting knives (10). This makes parts less expensive and reduces the time to change the knives (10) as there are fewer parts to loosen and tighten.

Abstract: The invention relates to a baby pacifier comprising an actual nipple part (20) and a shield of the pacifier. The actual nipple part comprises a piece made of elastic or resilient material to be held in the baby's mouth, between the middle section of the palate and the tongue, on which piece the baby exerts suction by the movements of the jaws and the tongue. According to the invention, the actual nipple part (20) is shaped so that its cross-sectional profile (21), viewed in a vertical cross-sectional plane of the buccal cavity, is elongated so that protrusions (26, 28) directed from the middle (23) of said cross section to both sides extend to the alveolar ridges (12, 14) and/or the teeth (16, 18) of the baby's upper jaw. Said protrusions are shaped so as to create from the baby's sucking motion essentially lateral outward pressure on the inside of said alveolar ridges and deciduous teeth.

Granted: 2001-10-09
Abstract: An automatic transmission clutch plate provides reduced drag in a wet clutch environment by employing independent offset slots through a friction lining applied to an annular clutch plate. The slots extend through the friction lining from at least one inner or outer peripheral edge of the ring to a terminating point between the radially inner and outer edges. In addition, slots through the friction lining extending from the radially inner edge are offset from the grooves extending through the lining from the radially outer edge. Preferably, the friction lining is formed by segments, and slots can be conveniently formed through the lining between radial edges spaced apart from each other on adjacent arcuate lining segments. In addition, the arcuate segments preferably include overlapping ends to form the offset slots.

Abstract: A reclaimer system is provided for collecting and recycling a viscous coating batter in a foods processing line, particularly such as in a production line for making batter coated French fry potato strips. The reclaimer system comprises an elongated collection trough mounted at the downstream end of a product conveyor used to transport batter coated food products to a fryer, wherein the conveyor is positioned to collect excess batter dripping from the conveyor and the food products and further wherein this excess batter would otherwise undesirably fall into the fryer. A paddle is reciprocated back and forth within the trough to sweep collected batter therein from opposite open ends of the trough into appropriate collection vessels or funnels for recycling. The trough is water cooled to prevent significant cooking of the batter therein, and the paddle includes a central overflow port to permit large quantities of batter to spill therethrough without being swept over the longitudinal edges of the trough.

Abstract: A recording device which improves a response time to write data by reporting to a host computer the completion of writing operation prior to the completion of writing redundancy data.  Data writing command information from the host computer is stored in a command/status memory backed up by a power source in an array controller, and the completion of writing operation is reported to the host computer at the time of the completion of writing updated data prior to the completion of writing redundancy data.  Redundancy data is written as a background process.  If redundancy data could not be written due to any abnormality of the power source or the like, such redundancy data may be generated from the data in other disk units of the same redundancy group in accordance with writing command information stored in the command/status memory, thereby completing the writing of redundancy data.
