Title: Encapsulated gel breast prosthesis and method of making
Inventor: SCHULZ MICHAEL W
IPC: A61F2/52
Filed: 1993-09-01
Abstract: An encapsulated gel breast prosthesis and method of manufacturing therefor is provided wherein a nipple/areola member and gelled breast body are disposed within an inner skin and outer skin which define the exterior shape of the breast prosthesis. The nipple/areola member has a shape, color and hardness simulating the natural shape, color and hardness of a human breast. The encapsulated gel breast prosthesis is fabricated by forming an outer skin and an inner skin. The outer skin is shaped to simulate the natural contour of a woman's breast and includes a region corresponding to the nipple and areola of the breast. A nipple/areola member having a shape, color and hardness, which simulates the natural shape, color and hardness of a woman's nipple and areola is disposed between the outer and inner skins which are then sealed together along their peripheries. This forms a capsule with the nipple/areola member enclosed therein. The capsule is then filled with a gel-forming composition through an opening in the capsule.      The opening is sealed and the gel-forming composition is cured into a gel with the nipple/areola member adjacent to the nipple and areola portion of the outer skin.

Title: Condiment Dispensing Bottle
Inventor: LEE GARY K
IPC: A47G19/18
Filed: 1994-11-01
Abstract: A bottle which may be in a straight-up position for storage and in an inverted position for dispensing of condiments, such as ketchup, mayonnaise, mustard, etc.  The top has a cap which may be removed and replaced by a dispensing nozzle.  The bottom has two parallel ridge members and has a hole in the flat area therebetween that is closable with a tethered plug.  When the bottle is ready to be used for dispensing condiments, the cap is replaced with the dispensing nozzle and the bottle is turned upside down.  At this time, the tethered plug is removed so as to release pressure in the bottle so its contents may escape through the dispensing nozzle.  The bottle is of shape and weight so that when inverted and hung on a stand, it will hang properly perpendicular to the ground.  The bottles are also shaped so that they will nestle against one another with very little clearance.  The bottle can be filled with condiments, inverted for dispensing through the dispensing nozzle, and the plug from the vent hole is removed when the bottle is hung upside down and is used.  At the end of the day, the tethered plug is placed in the vent hole, and the bottles are then placed up so they can be stored in refrigeration units.

Title: Multiple function heat pump
Inventor: MUELLER HERBERT R
IPC: F24F1/02
Filed: 1995-03-03
Abstract: The invention described herein pertains to an air cycle heat pump contained  in a single and compact unit which is capable to perform the functions of a heat pump, a de-humidifier, and an air exchanger with energy recovery capability. The unit consists basically of two superimposed rectangular compartments.  Two air circuits, one for the upper or condensing compartment, the other for the lower or evaporating compartment utilize their individual fan, and through an arrangement of air valves either of the circuits can communicate with the outdoors, the indoors or exclusively the indoors depending on the particular mode being asked for. The outstanding feature of this unit is an especially designed evaporator.  The latter consist of evaporator slabs arranged in a zig-zag pattern on a circular base which can be rotated with respect to the air stream supplied by the evaporator fan.  Rotated into one position, the slabs will present a surface area to the air stream which is the sum total of all the slabs combined, while in the other position all the slabs are presenting a parallel arrangement  so that the entire air stream will flow consecutively through each slab. The former case is principally required when the unit is in a heating mode to reduce frost accumulation on the evaporator fins, while the latter case exhibits its main advantage during the de-humidifying mode when the air should be cooled down to maximum for greatest extraction of moisture.  Placing the evaporator into any intermediate  position will allow it to handle a variety of air conditions in either the cooling or de-humidifying modes. The unit would typically be installed in a basement and would be connected to the outdoors via two ducts, the latter supplying outdoor air when the heating, cooling or fresh air exchange modes are called for. These ducts are capable of being closed off by a pair of shut-off valves integrated into the upper compartment, the latter being placed in the closed position when the unit is not in use or the de-humidifying or de-frost modes are in demand. Alternatively the unit could also be installed outdoors with only two ducts required to connect to the indoors ducting system.

IPC: H02M7/48
Filed: 1993-10-08
Abstract: A high efficiency static series resonant converter (22, 100, 200, 300) and method for converting power between two electric AC and/or DC circuits (24, 25; 124, 125; 224, 25; 24, 325) includes a resonant tank (60, 160) coupled to a link current synthesizer (70) for generating a train of unipolar link current pulses (Fig. 7) with controllable duration zero and nonzero current segments. A blocking switch (80) deactivates oscillation of the resonant tank (60, 160) in initiating each link current pulse, which is subse-quently clamped by a buffer inductor (95). Each pulse is terminated by natural commutation through resonant oscillation. The pulses are substantially squarewave and have a high duty cycle leading to minimal peak current values. Minimal switching losses are incurred by switching at substantially zero voltage and zero current. Other features include blackout ride-through capability, bi-directional four quadrant operation, unbalanced load operation, voltage step-up without transformers, and input and output switch assemblies (40, 50; 40, 150; 240, 50; 340, 50) constructed from unidirectional switches, such as low-cost and robust single thyristors.
