Title: Apparatus and method for forming and hydropiercing a tubular frame member
Inventor: ROPER RALPH E
IPC: B21D26/02
Filed: 1993-08-25
Abstract: APPARATUS AND METHOD FOR FORMING AND HYDROPIERCING A TUBULAR FRAME MEMBER A method and apparatus for forming complex shaped frame members from a tubular blank where the blank is transferred from station to station and various tooling are performed on the blank at each station. For example, at a first station the blank is expanded into a tube having a varying cross-section throughout the length of the tube by applying pressure to the interior of the tube and compressive force to the opposed ends of the tube preferably simultaneously. At another station, the expanded tube is preformed by introducing a bend therein. The bend in the preformed tube is then increased at another station. While the expanded tube is being preformed and bent, the flow of material into the die cavity at those stations is controlled to reduce the amount of folding that may occur. The shape of the frame member is finished at another station by introducing a lateral bend and varying the crosssectional configuration of the bent tube. Holes may then be pierced into the finished frame member at another station by pressurizing the interior of the frame member with hydraulic fluid and striking the frame member with a piercing punch. Final stations crop the ends and flush the interior of the frame member before it is unloaded for further transport.
Patent CA-2106174-A1 (CA)
Inventor: MASAKI RYOSO
IPC: B60L3/00
Filed: 1993-09-14
Abstract: An electric vehicle control system for driving a battery powered motor with use of power inverters. First and second inverters are connected with the respective three-phase primary windings of an induction motor. If one of the inverters fails, failure detection circuits detect it, and a control unit stops the failed inverter and allows the other normal inverter to drive the induction motor to move the electric vehicle. Driving the single motor with a plurality of power inverters allows the electric vehicle to move and run even if one of the power inverters fails.

Title: Clinical cartridge apparatus
Inventor: LAPIDUS STANLEY N
IPC: C12M3/08
Filed: 1993-09-20
Abstract: ABSTRACT A cartridge-like holder or carrier for automatic operation with a specimen processor has a frame for removable and replaceable alignment in operative engagement with the specimen processor and has multiple supports, each of which removably and replaceably supports an implement such as a container of a biological specimen having cellular particles suspended in a liquid, a filter device for use in collecting cellular particles from the liquid in the sample container, a viewing screen onto which the collected cellular particles can be transferred from the filter device and, further, an output container for receiving the viewing screen with the cellular particles thereon. A transfer mechanism on the apparatus is operable for the automatic transfer of the viewing screen from a support on the frame, where it received the cellular particles, to an output container at a further support on the frame. The cartridge apparatus brings to the specimen processor the sample and all disposable devices, i.e., sample contacting implements, and receives the final prepared specimen and all waste materials anddisposables, thereby leaving the processor clean of contact with the sample and operative with successive samples, by way of separate cartridges, without inter-sample cleaning and without risk of inter-sample contamination.

Title: Operator work station having a monitor support assembly
Inventor: GRESHEM DAVID
IPC: H04N5/64
Filed: 1993-10-01
Abstract: OPERATOR WORK STATION HAVING A MONITOR SUPPORT ASSEMBLY     Abstract of the Disclosure An operator work station defined by a wall having a support assembly for mounting a monitor within a housing within an opening in the wall, the support assembly enabling the monitor to have four degrees of freedom.  The support assembly includes a counterbalanced horizontal bar slidably disposed in the opening parallel to the wall for enabling the monitor to be raised and lowered parallel to the wall.  Bearing rigidly secured to the bar receive rods rigidly secured to a horizontal plate, the movement of which enables the monitor to be moved perpendicular to the wall.  A shaped plate pivotally connected between the horizontal plate and the housing enables the monitor to rotate about a vertical axis.  Such rotation is limited by posts rigidly secured to the bar which engage the sides of the shaped plate when the shaped plate is rotated with respect to the wall.  A shutter pivotally mounted within the housing for rotation around a horizontal axis has upper and lower arc-shaped panels which frictionally engage the upper and lower plates of the housing to enable the monitor to rotate around the horizontal axis to adjust the tilt of the monitor.

Filed: 1993-05-19
Abstract: A telecommunication device for the deaf (12, 14, 16, 20, 22, 24, 26, 28) operates under conventional Baudot communication protocol, but has enhanced features enabling it to handle interrupts either from a conventional or a similar TDD. The improved TDD is also capable of pseudo-duplex communication with a similar TDD in which each device transmits packets of characters alternatively to the other thus making it appear to the users that simultaneous transmission is occuring. The implementation of these features is done in such a way that the TDD is fully capable of communication with existing TDD devices and the device obeys normal rules and conventions for Baudot communication.

Title: Data compression system
Inventor: SHAPIRO JEROME M
IPC: H04N7/26
Filed: 1992-10-01
Abstract: A data processing system augments compression of non-zero values of significant coefficients by coding (1410, 1412) en-tries of a significance map independently of coding the values of significant non-zero coefficients. A dedicated symbol represents a zerotret structure encompassing a related association of insignificant coefficients within the tree structure, thereby compactly representing each tree of insignificant coefficients. The zerotree symbol represents that neither a root coefficient of the zerotree structure nor any descendant of the root coefficient has a magnitude greater than a given reference level. The zerotree structure is disclosed in the content of a pyramid-type image subband processor (1408) together with successive refinement quantization and entropy coding (1418) to facilitate data compression.

Title: Farming method using waste material
Inventor: ROSSET RENE R
IPC: A01C23/00
Filed: 1994-05-20
Abstract: A method of farming comprises collecting waste material such as manure from animal farming, or effluent from food processing plants or the like in a closed container, stirring and aerating the material within the container and adding yeast and phosphoric acid to increase aerobic bacterial activity while reducing anaerobic bacteria and rendering the material into a pumpable liquid. The material is then spread across the ground by a spreading action by pumping the material through a pipe carried on the reel of a vehicle having a boom of the order of 100 feet in width so that the material is sprayed onto the ground in an even spreading action at a rate of the order of 1000 to 5000 gallons per acre. Simultaneously an oxidizing agent such as hydrogen peroxide is sprayed onto the material, preferably immediately before the material. Prior to spreading, crop residue on the ground is chopped to small length and broken so that the oxidizing agent acts on the straw and allows the high level of aerobic bacteria in the waste material to decompose the straw with the waste material in a rapid action. Subsequently the soil is incorporated with the crop residue and material to a depth of two inches.
