Title: Intelligent setpoint changeover for a programmable thermostat
Inventor: SHAH DIPAK
IPC: F24F11/00
Filed: 1992-11-06
Abstract: INTELLIGENT SETPOINT CHANGEOVER FOR A PROGRAMMABLE THERMOSTAT     ABSTRACT OF THE DISCLOSURE An apparatus to match initiation of temperature changeover settings of a thermostat to a duty cycle of an air temperature conditioning plant without degrading the comfort level of the area of temperature modification. The apparatus prevents short-cycling of either a heating or a cooling system which can occur due to changes in the setpoint temperature. Apparatus operates by determining the length of time of "on" portion and "off" portion of the duty cycle of the air temperature conditioning plant. It then determines the time until the upcoming cycle of the temperature conditioning plant and either advances or delays the temperature changeover until the beginning of the upcoming "on" period or the upcoming "off"period of the upcoming duty cycle, or the last "on" period or the last "off" period of the last duty cycle of the air temperature conditioning plant.

Title: Redundant switched reluctance motor
Inventor: HORST GARY E
IPC: H02K29/00
Filed: 1993-01-08
Abstract: Abstract of the Disclosure A multiple phase switched reluctance motor (30).  A stator assembly (32) has a plurality of inwardly salient teeth (34a-34l) terminating at a central bore (36).  A rotor assembly (38) is disposed for rotation in the bore and has a plurality of rotor teeth (42a-42d).  The stator assembly has at least one redundant pole set for each motor phase.  The rotor assembly has a corresponding proportional number of rotor teeth.  The redundancy of the poles helps distribute ovalizing forces in the motor assembly,  This lessens the effect of these forces and reduces motor noise produced by the assembly in response to the forces.  In addition, the stator can have multiple teeth per pole and the rotor a multiple of the determined rotor teeth.  The number of rotor teeth exceeds the number of stator teeth so the rotor teeth overlap the stator teeth.  This improves starting torque in a desired direction of motor rotation.

Title: Biodegradable polymer blends for drug delivery
Inventor: DOMB ABRAHAM J
IPC: C08L67/04
Filed: 1992-01-31
Abstract: Blends of polymers having properties distinct from the individual polymer components, and that are suitable for use as carriers of pharmaceutically active agents, are prepared from two or more polyanhydrides, polyesters or mixtures of polyanhydrides and polyesters. The blends have different properties than the polymers used to prepare the blends, providing a means for altering the characteristics of a polymeric matrix without altering the chemical structure of the component polymers. Blends of various polyanhydrides, polyesters, and polyanhydrides and polyesters, containing pharmaceutically active agents, are prepared using solvent mixing or melt-mixing procedures. It has been discovered that the rate of release of the agent from the blends is different than the rate of release from the individual polyanhydride and polyester polymer components, being a function of the blend composition.

Title: Valve
Inventor: VAN DE WIEL PETRUS NICOLAAS RO
IPC: B65B/
Filed: 1992-03-02
Abstract: Valve comprising a valve stem (6) and a valve disc (7). The peripheral edge (8) of the valve disc in the closed position comes to-rest in a sealing manner against the valve seat (10) of the corresponding valve housing. Between this seal-ing peripheral edge and the valve stem the valve disc is partially made of elastical-ly yielding material. The position of the valve stem guide is such that it is possible to move the valve further in the direction of closure after the peripheral edge rests against the valve seat. This means that a vacuum can be created with the aid of the valve according to the invention. Such a vacuum can be used in filling devices for drinks. The nozzle in this case is made of a relatively flexible material which closes when vacuum is created. In this way after-dripping of drinks in, for exam-ple, juice packs can be avoided.
