Inventor: BIEN PAUL R
IPC: F16H57/023
Filed: 1993-02-10
Abstract: In a drive with twin helical drive gears on an axle driven by a motor with pinions at either end wherein the motor housing and axle housing are axially located by a key in mating keyways, an offset key is used to obtain axial housing adjustment by the amount of the key offset.  The pinions are mounted to the motor with their teeth substantially aligned and the gears are mounted to the axle with their teeth substantially aligned, and the housings are axially positioned by an offset key to compensate for errors in tooth alignment to assure that gear backlash is centralized on both ends of the motor when the rotor is substantially centered in its range of end play.

Patent CA-2089836-A1 (CA)
Inventor: SOLOMON ROBERT C
IPC: G06F3/06
Filed: 1993-02-18
Abstract: A method for handling data in a plurality of data storage disks having user data sectors and corresponding parity sectors, the method being used when the disks are being operated in a non-degraded or a degraded mode wherein a non-volatile RAM is used in an array control processor which controls the operation of such disks. When new data is to be written into the array, the non-volatile RAM stores information identifying the array, the starting sector into which data is to be written and the number of sectors to be used for writing the new data so that parity and data entries in corresponding sectors can be matched when a power failure occurs. Further, when opening a new array, the data and parity entries in corresponding sectors can be matched and verified, the operation for such matching being performed in between other operations that are being performed by the control processors (i.e., in the "background" thereof).

Title: Molded plastic microwave antenna
Inventor: KLEBE DOUGLAS O
IPC: H01Q25/02
Filed: 1993-05-06
Abstract: A microwave radar antenna that substantially comprises molded or extruded thermoplastic components that are assembled into completed assemblies, are then metallized by either electroless copper or are electroplated with copper to achieve RF conductivity. The finished subassemblies are joined together forming the completed antenna. The molded, metallized, plastic antenna uses a thermoplastic material, such as polyetherimide, or suitable high strength, high temperature thermoplastic that is used to injection mold or extrude detailed microwave components. The molded components are assembled, using epoxy adhesives, solvents or other mechanical method into microwave subassemblies. These subassemblies are then either electroless copper plated or electroplated to provide RF conductivity. The metallized subassemblies are then joined together using mechanical methods to form a completed radar antenna,replacing heavier more costly metal radar antennas. Specifically, the molded, metal-lized, plastic antenna is comprised of an antenna aperture and electromechanical phase shifter section, centerfeeds comprising a horizontal feed network, interconnecting waveguides, a vertical feed network including conventional rotary field phase shifters, and a sum and difference monopulse feed network. The antenna also includes a suit-able beam steering controller that provides electronic antenna beam steering and power supplies. The use of the present microwave antenna incorporating molded, metallized, plastic components results in an antenna having better performance, lighter weight, and much lower manufacturing costs than conventional metal antennas.

Title: Spin flow necking apparatus and method of handling cans therein
Inventor: DOWNIE ROBERT
IPC: B67B3/00
Filed: 1993-05-14
Abstract: Abstract of the Disclosure A multi-station machine for necking-in the open end of a metal container body includes a plurality of necking spindle assemblies mounted at circumferentially spaced locations on a tooling disc turret in coaxial alignment with corresponding base pad spindle assemblies mounted to a base pad turret.  The turrets are co-rotatable with a main turret shaft.   Cam controlled tooling activating assemblies are mounted on the tooling disc turret to control the necking-in movement of an eccentric roll and  an  external  forming roll  in  each necking  spindles  in synchronism with delivery of vacuum suction through the base pad spindles  which  clamps  the  container  bottom  walls  to  the respective  base  pads.    A  sequential  latching  arrangement associate  with  the  tooling  activating  assemblies  prevents tool-to-tool contact between the outer forming rolls with the eccentric rolls in the absence of container bodies on station. The vacuum manifold arrangement feature the supply of high volume, low suction vacuum to a small number of stations in the vicinity of the infeed location to rapidly locate the container bodies on the base pads.  A lowe volume, high suction vacuum supply to the downstream spindles ensures proper clamping suction to properly maintain the containers on the base pads during necking.  In the absence of containers at various stations, the high volume, low suction vacuum is subject to leakage only at a small number of stations at the infeed while vacuum leakage in the remainder of the stations is insufficient to lower clamping pressure to unacceptable levels.

The support is movable relative to the frame, to enable precise positioning of the joining equipment relative to the pipe ends to be joined. A support cart is provided to receive and movably support successive pipe sectionsreceived from the joining machine.

Title: System for monitoring circuit breaker operations and alerting need of preventative maintenance
Inventor: SWINDLER DAVID L
IPC: H01H11/00
Filed: 1993-05-10
Abstract: A system which automatically monitors critical circuit breaker (C) operating parameters during each operation of the circuit breaker. Monitored parameters include the currents being interrupted, trip coil voltage and current, position of the contacts, initiation of closing, over travel of the contact mechanism on closing, contact opening and closing point and pressure in SF6 circuit breakers. These parameters are sampled and stored in memory (M) in the circuit breaker. The sample memory is connected to a local microcomputer (M) which is in communication with a host computer (H). Upon receipt of a command from the host computer (H) a local microcomputer in the circuit breaker (C) transmits the sample data to the host computer (H) for storage and analysis. The host computer (H) compares the stored data for each operation with acceptable operation curves. If the data indicates operation outside of various acceptable ranges, the maintenance department is automatically notified of the potential problem, to allow preventative maintenance and further testing, if desired.
