Title: Method for biological purifying of waste waters
Inventor: KOSEV ANDREJ R
IPC: C02F3/08
Filed: 1989-06-02
Abstract: This method is intended for use in the biotechnology and food industries. It is a highly effective method, which makes it possible to control the thickness of bio-film thickness and maintain it within optimal, prescribed limits for a given bioprocess. Biological purification is performed using a three-phase pseudo boiling layer of gas-liquid-solid phase in a cone shaped bio-reactor at gas- and liquid- phase rates of up to 0.06 m/sec and of up to 0.08 m/sec respectively, measured against the largest surface section of the cone bed of the bio-reactor. A three-phase fountaining layer is created in the bioreactor, while in its cone bed a dense pulsating pseudo-boiling three-phase layer is formed. As the solid particles pass through these layers, in correlation to the increased biomass on the surface of the particles, the bio-film is regulated and its average thickness is maintained constant.

Patent CA-2007438-A1 (CA)
Title: Hydraulic Platform Lift for Truck Trailers
Inventor: GRAY RALPH E
IPC: B60P1/44
Filed: 1990-01-09
Abstract: A hydraulic platform lift for use on trucks and truck trailers has two hydraulic cylinders, one on each side of a door.  The cylinders are phasing cylinders in that one cylinder is larger than the other cylinder by a specific ratio.  The cross-sectional area of the fluid in the rod end of the larger cylinder minus the area of the rod is equal to the cross-sectional area of the smaller cylinder.  A connecting line interconnects the rod end of the large cylinder with the cap end of the small cylinder. Hydraulic fluid can be directed by control means into the cap end of the large cylinder or the rod end of the small cylinder.  For upward movement, hydraulic fluid is forced into the rod end of the small cylinder.  This in turn forces hydraulic fluid through the connecting line into the rod end of the large cylinder, thereby raising both pistons.  For downward movement, hydraulic fluid is forced into the cap end of the large cylinder, thereby forcing fluid out of the rod end of the large cylinder and into the cap end of the small cylinder.  This causes both cylinders to move downward.  The platform lift also has a self-levelling feature whereby the pistons can be made level with one another by moving the platform into an uppermost position.  The operational mechanism is located entirely at the sides of the trailer.  The lift platform can be made to exert a positive upward force or a positive downward force during use.

Title: Cvd grown transition metal carbide and nitride whiskers
Inventor: BAUER CHARLES E
IPC: C30B25/00
Filed: 1990-04-27
Abstract: ABSTRACT OF THE DISCLOSURE A chemical vapor deposition process for producing single crystal whiskers of metal carbides, nitrides, or carbonitrides is provided.  The process includes flushing a reactor having a suitable growth substrate surface heated to 1120 to 1225 degrees C and flowing reactant gases past the growth substrate to form whiskers.  The reactant gases comprise a metal halide and one or more of nitrogen and methane.  The atomic ratio of carbon and nitrogen to metal is about 0.7:1 and 20:1, respectively.  The volume ratio of hydrocarbon and nitrogen to hydrogen is about 1:37 and 1:1 6, respectively.  The preferred growth substrate materials are nickel powder dispersed onto alumina oxide plates or nickel electrolytically deposited onto TiC or TiN coated aluminum oxide plates.  The whiskers may be subjected to a post-growth treatment to remove the residual nickel catalyst used to grow the whiskers. The process is a two-step procedure.  In the first step, the whiskers are treated at between 350 to 400 degrees C at one atmosphere pressure with 2.8 slm of HCl in 11.4 slm of argon gas for approximately one hour to convert the nickel residual catalyst to NiCl2.  In the second step, the whiskers are then heated to 1000 degrses C and treated with 11.4 slm of argon for one hour to cause the NiCl2 to sublime.  This results in the reduction of the residual nickel content of the whiskers from 1-2 wt% to 0.2 wt%, an order of magnitude reduction, without adversely affecting the physical properties of the whiskers.

Title: Multi-element antenna system and array signal processing method
Inventor: COOK JAMES H JR
IPC: H01Q25/02
Filed: 1990-05-24
Abstract: MULTI-ELEMENT ANTENNA SYSTEM AND  ARRAY SIGNAL PROCESSING METHOD                   ABSTRACT OF THE DISCLOSURE A multi-element antenna feed method and system which has superior side lobe characteristics over previous electronically scanned beam approaches is provided. A multi-element antenna feed system generally comprises a multi-element antenna, an antenna array pro-cessor, a receiver, a signal processor for automatic tracking of tar-gets, and an antenna steering control mechanism. The multi-element antenna may comprise alternate configurations and the antenna array processor is coupled to the multi-element antenna. The antenna array processor particularly comprises a diode switching array for combin-ing at least one output of the elements of the multi-element antenna with at least one other output of the multi-element antenna switchably selected via the diode switching array. The method allows control of the antenna system side lobes in both the scanned offset beam plane and the orthogonal plane by an amplitude weighted combi-nation of the selected element beams. This results in an improved capability to reduce crosstalk between two orthogonal tracking chan-nels, offset beam control versus frequency, and a wide frequency bandwidth.

Abstract: RETRACTABLE CONTROL UNIT FOR REFRIGERATORS     ABSTRACT OF THE DISCLOSURE         A retractable temperature control for refrigeration units includes a control panel pivoted for movement between an extended, accessible position and a retracted position in which it is enclosed within one of the insulated walls of the unit.  Mounted on the panel are two operators, one of which controls the temperature of a thermostat and the other of which controls the position of a damper.  Adjustment of the operator associated with the thermostat controls the tempera-ture of one compartment in the refrigeration unit and adjust-ment of the other operator controls the position of a damper, and in turn controls the differential temperature between the two compartments provided by the refrigeration unit.  The thermostat and the damper control are structured so that movement of the control panel between the retracted and extended positions does not affect the adjustment thereof. When the controls are in the retracted position, they do not interfere with the placement of articles stored within the refrigeration  compartments.   Further,  retraction of  the controls prevents accidental damage of the controls and/or accidental change in the adjusted positions thereof.
