Title: Apparatus and method for heating and cooling with a refrigerant
Inventor: MATSUURA TAKAAKI
IPC: F25B5/02
Filed: 1991-07-25
Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus and a method for heating and cooling with a refrigerant wherein the refrigerant is compressed by a compressor, and circulated to and from the compressor through a condenser, an expansion valve and an evaporator, in this order.          A first fluid is heated with the heat generated in the condenser, and a second fluid is cooled with the cooling effect or cold generated in the evaporator.  When heat is low and a temperature of the first fluid is decreased, the flow passages of the refrigerant are changed from entering into the evaporator to entering into a second heat-exchanger wherein the refrigerant is heated, and the heated refrigerant is entered into the compressor and circulated.          When the cooling effect or cold is low and a temperature of the second fluid is increased, the flow passages of the refrigerant are changed from entering into the condenser to entering into a first heat exchanger wherein the refrigerant is cooled, and the cooled refrigerant is entered into the evaporator and circulated.
Patent CA-2047926-A1 (CA)
Title: Neck finish for containers of rigid materials
Inventor: LUCH DANIEL
IPC: B65D1/40
Filed: 1991-07-25
Abstract: ABSTRACT      Neck finishes suitable for containers formed of rigid materials are shaped to overcome problems which would otherwise occur if standard closures which perform satisfactorily with less rigid containers are used. One problem is that plugs (inner skirts) of closures are cut or shaved if they are oversize relative to the inner neck diameter. This problem is overcome by forming a chamfer or radius at the lead-in to the inside corner of the neck. A second problem ("ovality") occurs when the neck is not uniformly round; this problem is overcome by forming a cut-out section at the upper outer corner of the neck so that the maximum neck diameter engages the inside of the outer cap skirt below the top edge, thereby lessening outward distortion of the outer skirt.

IPC: B60C11/12
Filed: 1991-11-01
Abstract: The present invention relates to a tread for a ribbed pneumatic tire featuring circumferentially extending ribs, at least one of which and preferably all of the ribs contain a high density siping zone.      Each high density siping zone is (a) circumferentially extending; and features (b) an inside edge and an outside edge with a total width between the inside edge and outside edge ranging from about 1.4% to about 4.5% of the overall tread width; (c) the outside edge of each high density siping zone being located from the nearest rib edge by a distance ranging from about 0.2% to about 1.9% of the overall tread width; (d) about 50% to about 80% of the surface area in each high density siping zone being ground contacting with the remaining percent of area being siping; (e) no more than 50% of the siping arranged in the circumferential direction; and (f) at least 75% of all sipes within the high density siping zone are arranged so that their end portions are laterally aligned with or overlap in the circumferential direction with an end portion of another sipe within the high density siping zone. When the tread width of the pneumatic tire is for example eight inches (203.2 mm), the total width between the inside edge and outside edge of the high density siping zone ranges from about 3 to 9 mm and the outside edge of each high density siping zone is located from the nearest rib edge by a distance ranging from about 0.5 mm to 4 mm. The high density siping zones reduce rib edge erosion wear by creating a weakened zone without the tendency of tearing.

Title: Electrical machine
Inventor: WUEST BERNHARD
IPC: H02K9/19
Filed: 1992-05-11
Abstract: ABSTRACT OF THE DISCLOSURE      A transversal flow machine with a central, disk rotor having ring-shaped pole elements which extend axially outwardly from the disk toward both sides of the housing.  These pole elements are radially outside and radially inside surrounded by outside and inside stators which, in turn, feature ring-shaped windings.  For the dissipation of heat generated in the stators themselves, the stators are surrounded by ring-shaped cavities through which flows in a peripheral direction a coolant introduced through the housing.  The arrangement of the channels is such that a tangential flow is created within the cavities. Also, the housing itself is penetrated by channels, so that the housing is additionally cooled.  The housing is also surrounded by an outer casing, enabling the use of the electrical machine under operating conditions requiring a low temperature of the casing surface.
