Abstract: Three or more diaphragm pumps (12,14,16) are interconnected to sequentially receive an activation fluid from corresponding piston and cylinder pumps (18,20,22) synchronized by a control mechanism (24) which includes a distributor plate (42) with directive shallow slots (80,82,84) for conduiting activation fluid to a porting plate (44) and via openings (60,62,64) to the piston and cylinder pumps (18,20,22).

Abstract: Allergy testing apparatus (10) includes a housing (18) with opposed parallel sidewalls (22, 24) and a pair of pressure plates (30, 32) located therebetween. The surfaces between each sidewall and adjacent pressure plate are configured into shallow openings (28, 36), each set of complementary facing shallow openings forming a cylindrical opening (35). Threaded bolt (38) on being advanced secures picks (12) within individual openings (35). In use, the entire assembly of picks (12) is lifted by the gripping bar (26) and simultaneously pressed against the patient's skin.

Abstract: A golf club shaft (12) is provided with ringlike shaft stiffening bodies (22) at a given location along the shaft in order to locate the shaft flex point appropriately for a particular individual. Each stiffening body (22) consists of a quantity of an epoxy and glass fibers mixture which is molded about the shaft (12) and sets up to a rigid condition.

Abstract: A toilet (20) has an upper part (28) and lower part (30) joined together. A foul air unit (22) mounted to the rear of the seat is interconnected via a flexible tube (16) with a filtration unit (12) mounted conveniently adjacent. A fresh air outlet (24) mounted on the seat front interconnects with the unit (12) via a flexible tube (18). A further version exits pressurized foul air to the exterior of the toilet room without filtering.

Abstract: Tissue (10) from the colon or bowel is pretreated with a Ringers solution and mounted onto a ring (12) submerged in oxygenated Ringers solution (32), with first and second current electrodes (34,36) and first and second voltage electrodes (38,40) positioned within the solution (32) closely adjacent the tissue. A sequence of current pulses of different frequencies (44) covering a broad frequency range are applied via electrodes (34,36) to the tissue and corresponding impedance and resistance values are obtained (46). Comparison of impedance/resistance values establishes separate and distinct ranges of values for normal, cancerous and premalignant tissues.

Abstract: A system (10) for establishing bypass of a failed battery cell (18) includes a failed cell sensor (26) which on sensing a failed cell generates an electric signal that destroys clamping relation of two retaining wire spools (24) to release retaining means (14,16). Such release enables a unitary plunger assembly (28) to be moved by a spring (49) to position a cylindrical pin contact (52) in electrical shorting relation to the first and second electrodes (57,58) connected across the cell (18).

Abstract: A cushion (10, 12) has a plenum (16) which includes a plurality of flexible plastic woven tubes (34) held within a pair of similarly woven sheathes (38,40). The plenum has its sides and bottom covered by an air impermeable (14) layer with the top covered by an air permeable layer (20). A low to medium density foam pad (19) is located between the plenum (16) and the top layer (20). Conditioned air is provided to the cushions (10,12) from a Stirling cycle heat pump (44).

Abstract: An electrical receptacle (32) mounted to an aircraft (10) includes a pin contact assembly (34) having a pin body (62) releasably threaded within a threaded insert (38). A collet (70) enhances mechanical securement and electrical contact between the insert (38) and pin body (62). The outer end of the pin body (62) is configured (76) to receive a wrench for assembly disassembly of the parts.

Abstract: A luggage case (10) with a retractable handle (17) includes handle retraction apparatus (24) located within the luggage case adjacent a bottom wall (20) and covered over by a fabric panel (34). Inner mounting parts for luggage case wheels (14) are also located under the fabric panel (34). The panel (34) includes a central flap (58) releasably secured to the panel by a zipper (60). When the flap (58) is released it provides an access space (56) for repair or replacement of retraction apparatus (24) and wheels (14) or wheels mounting.

Abstract: A cage (28) constructed from a metal blank 26 for encompassing a plurality of nested conical washers (43) having a common threaded bore to form a nut (28). The cage side walls are free of separable openings (22) that would result in relaxation ("blossoming") of nut parts during nut tempering causing undesirable separation and misalignment of the nut threads.

Abstract: A door hinge pad (12) and body hinge pad (14) are respectively mounted on the door and body of an automotive vehicle, and interrelated for relative swinging movement by a pivot pin (16). A pair of spaced apart camming surfaces 30 integral with the door hinge pad (12) are resiliently tracked by first and second rollers (68) connected to opposite ends of a compression spring (66) integrally related to the body hinge pad (14). Swinging movement of the door hinge pad (12) away from the closed position moves the rollers (68) over a camming raised portion into a dwell (34) serving as a limit stop at a predetermined door opening angle.

Abstract: A high-SPF composition is provided which is quick drying, waterproof and anti-perspiration penetrating which after application rapidly is very dry and soft to the touch comprising a sunscreen with both UVA and UVB components, an algae extract and aloe vera, and tapioca powder. In a further example, an enhancing agent consisting of styrene acrylates copolymer is added.

Abstract: An optical fiber socket terminus (28) has a fiber tip (30) received within a tip holder (32) that is welded (41) to a socket tube (36) slidingly received within a socket shoulder (44). A coil spring (38) extends about socket tube (36) between tip holder (32) and shoulder 44. Stop 49 is welded to end portion of tube (36) providing limit to shoulder (44) movement. Pin terminus (10) has a fiber tip (18) that is received within alignment bushing (60) along with the socket tip (30) to achieve proper end relation of the optical fibers.
