Inventor: BRADBURY DAVID
IPC: C02F1/42
Filed: 1992-02-24
Abstract: ABSTRACT OF THE DISCLOSURE:            METHOD FOR THE COMBINED REMOVAL AND     DESTRUCTION OF NITRATE IONS        Method for the combined removal and destruction of nitrate ions in an electrochemical cell which comprises an anode compartment containing electrolyte and an anode, a cathode compartment containing electrolyte and a cathode and a central compartment containing an anion exchange resin, the central compartment being separated from the anode compartment and the cathode compartment by an anion permeable membrane, which method consists essentially of the steps of (i)      passing an aqueous solution containing nitrate ions through the anion exchange resin in the central compartment of the cell, (ii)     passing an electric current through the cell in order to cause the nitrate ions captured on the anion exchange resin to migrate into the anode compartment of the cell, and (iii)    destroying the nitrate ions by subjecting them to reduction and oxidation reactions to form nitrogen and oxygen or water.        Step (i) may be replaced by passing an anion exchange resin washed with nitrate ion through the central compartment of the electrochemical cell.

Title: Vehicle for transporting alternative substances
Inventor: KELLEY OLIVER K
IPC: B60P1/00
Filed: 1992-04-10
Abstract: A trailer for selectively transporting either a first or second substance is disclosed.  The trailer includes a substantially flat bed and has two containers disposed thereon, each of which is capable of storing a different type of substance.  An operator may choose to transport materials in either one of the two containers, Accordingly, the container to transport the substance is shifted toward a balanced load distribution point along the trailer while the empty container is moved to one end of the trailer.  In the preferred embodiment, the two containers are coupled together so that the movement of one container along the trailer automatically causes a corresponding movement in the other.  One container moves along the trailer by virtue of a plurality of wheels while the other slides along rails separated by a bearing.  Movement of the containers is preferably accomplished by virtue of a hydraulic-powered winch which advances a chain in order to correspondingly advance a carrier plate longitudinally along the trailer.   A tilting mechanism is also included within the trailer for purposes of tilting one of the containers to that any substance stored therein may be exhausted or dumped out of a multi-hinged tailgate.  The multi-hinged tailgate of one of the containers permits access to the substance stored therein, either by dumping the substance or by side opening of the tailgate for immediate access to the substance stored within the container.

Patent CA-2079059-A1 (CA)
Inventor: KOMODA MOTOYOSHI
IPC: H05B44/00
Filed: 1992-09-24
Abstract: A driver circuit for a display device, in which first and second clock pulse generator circuits generate first and second clock pulses to a gate circuit for allowing the first clock pulse to pass when the first and second clock pulses are a high level, and by the output of the gate circuit, a combination of a transistor and an inductance generate a high voltage pulse.  The high voltage pulse is rectified in a triple voltage rectifying circuit to output a high voltage output for driving the display device such as EL elements, and the high voltage output can be reset by a low frequency pulse output from a discharge circuit.   As  a result, no inverter is required,  and a small-sized and light-weighted driver circuit is achieved with a long luminescence life of the EL elements and without noises offensive to the ear.

IPC: A22C25/17
Filed: 1992-11-04
Abstract: An apparatus for skinning fish fillets having the roller-presser shoe-structure comprises an oscillating knife (17) is particularly appropriate for skinning fillets of flatfish, i.e. fillets of fish which show a rather intimate and close connection between the skin and the muscle meat at least partially caused by fine tendons.  In order to improve the insufficient yield in fillet meat caused by the structure of such machines, and in order to obtain a remaining of the so-called silver mirror on the fillet meat, the presser shoe (6) carrying and guiding the oscillating knife (17) is arranged to pivot about the axis (9) of the roller (3) against spring force, and the pivoting movement is used for retracting the oscillating knife (17), so that the cutting edge (19) thereof comes to lie behind a stationary cutting edge (13) formed on the presser shoe (6) at the entrance side thereof.  Thereby, a change of the type of skinning cut occurs during the skinning after the initiating cutting by the oscillating knife (17) by the presser shoe (6) being entrained due to the entrance of the skin into the gap (8) between the presser shoe (6) and the roller (3).

When the outer member is made from gall-resistant material, the inner member made from 300 Series stainless steel can be provided with an elongate bearing surface therealong formed by surface hardening the inner member or coating the inner member with thin, dense chromium.  The outer tubular member can be made of 300 Series stainless steel with the inner tubular member including a distal tip made from gall-resistant material, a body made from 300 Series stainless steel joined to the distal tip and a bearing surface extending along the body.  A biocompatible lubricant can be disposed between the inner and outer members to increase wear and galling resistance of the surgical cutting instrument, and a sleeve bearing on the inner tubular member allows the surgical cutting instrument to withstand increased radial or side loads.

IPC: G11B27/00
Filed: 1991-11-15
Abstract: The automated library system (100) stores and retrieves media cartridges (1202) for an associated plurality of media drives (211-214). Within this system, a virtual robot is implemented to create multiple virtual media libraries within the single automated cartridge library system (100). This capability enables the use of a plurality of types of media within the single automated cartridge library (100) and a corresponding plurality of drive elements (211-214) within the library (100). Thus, each drive element (211-214) has associated therewith a number of object storage locations (201, 202) within the library (100) which contain media of a form and content that matches the drive element (211-214). The automated cartridge library system (100) manages the correspondence between object storage location (201, 202), media type, designated drive element (211-214) in an automated manner such that the single library (100) appears to the user as multiple independent libraries.
