Patent CA-1289205-C (CA)
Title: Symmetric integrated amplifier with controlled dc offset voltage
Inventor: VELLA-COLEIRO GEORGE P
IPC: H03F3/30
Filed: 1989-05-29
Granted: 1991-09-17
Abstract: SYMMETRIC INTEGRATED AMPLIFIER WITH CONTROLLED DC OFFSET VOLTAGE: Abstract A symmetric integrated FET amplifier (e.g., 30) is disclosed which exhibits a DC offset voltage that is insensitive to power supply variations, as well as variations in the threshold voltages of the FETs forming the amplifier. These variations are known to be most prevalent in InP-based FET amplifier arrangements. The symmetry is achieved by using a pair of impedance matching elements (e.g., 44, 46) in the input stage of the amplifier to essentially match the impedance of the input FET and its load element; a matching buffer FET (e.g., 48) and diode level shifting arrangement (e.g., 50) are used to match similar elements present in the output branch of the amplifier structure. The impedance matching elements, as well as the level shifting diodes, may all be formed with FET structures to minimize fabrication problems. In accordance with the symmetric arrangement of the present invention, the output DC offset voltage will be maintained at zero volts, regardless of the variations noted above. A multistage symmetric amplifier may then be formed simply by directly connecting a number of single stage symmetric amplifiers together in series.

Title: Hermetic compressor having resilient internal mounting
Inventor: GANNAWAY EDWIN L
IPC: F04B39/12
Filed: 1989-06-21
Granted: 1993-10-05
Abstract: ABSTRACT A compressor assembly is disclosed including a compressor mechanism resiliently mounted within a hermetically sealed housing.  The compressor mechanism includes a crankcase having a radially extending mounting flange portion, which is resiliently connected to the housing sidewall at a plurality of circumfer-entially spaced locations by a plurality of mounting assemblies.  Each mounting assembly comprises a rubber bushing received within a hole in the mounting flange, and a threaded stud that extends through a hole in the bushing and engages a threaded hole in a steel block welded to the housing sidewall above the mounting flange.  A washer and retaining nut on the bottom of the threaded stud suspendingly support the mounting flange.  In this manner, only a peripheral portion of the washer contacts the mounting flange circumjacent the hole therein, thereby minimizing noise transmission to the housing.  Lateral movement of the compressor mechanism is absorbed by the bushing.

Title: Watering system for greenhouse
Inventor: LUCAS GARY H
IPC: A01G9/24
Filed: 1989-09-29
Granted: 1993-04-27
Abstract: Abstract of the Disclosure A water sprinking system for greenhouses comprises two horizontal rails and a carriage movably mounted to the rails.  A fluid outlet disposed at a substantially midway point along the rails is connected to the carriage by a fluid transfer hose for guiding fluid to the carriage from the fluid outlet.  The hose has a first end portion extending from the fluid outlet along the first rail, a second end portion extending to the carriage along the second rail, and a middle portion connecting the end portions to one another.  Support elements, preferably in the form of hook members, are spaced from one another along the first rail for supporting the first end portion of the hose, while a plurality of roller members are spaced from one another along the second rail for rollably supporting second end portion of the hose.  A hosecar is movably mounted to the rails for carrying the middle portion of the hose.  A cable provided for maintaining tension on the hose is operatively connected to the hosecar to exert thereon a force directed along the path of the rails and essentially directly opposed to a force exerted on the hosecar by the hose.         Deflectors, preferably in the form of rollers, are provided on the hosecar for deflecting the hose from a first orientation occupied by the first end portion of the hose to a second orientation occupied by the middle portion of the hose and for bending the hose from one rail towards the other, so that the middle portion of the hose is disposed substantially per-pendicularly to the first end portion and the second end portion.

Abstract: An evaporable foam pattern for use in casting a metal part, such as an engine block.  The pattern includes a first evaporable foam section having an outer peripheral rim and an internal wall which is spaced from the rim.  The pattern also includes a second pattern section having a rim disposed in abutting engagement with the rim of the first section and having an internal wall spaced from the rim and disposed in abutting engagement with the internal wall of the first section.  A third pattern section is disposed outwardly of said second section and has a rim disposed in abutting engagement with the rim of the second section.  A layer of adhesive or glue is disposed between the abutting rims and between the abutting internal walls.  Load transmitting members interconnect the outer surface of the second pattern section with the inner surface of the third pattern section and are located in load transmitting alignment with the abutting internal walls so that an external clamping force applied to the outer surface of the third section during the gluing operation will be transmitted through the load transmitting members to the abutting internal walls to maintain the walls in tight bearing engagement.  The clamping forces are thus resisted by direction compression of the thin foam walls rather than by bending of the foam.
