Patent CA-1304768-C (CA)
Title: Multiple control circuit
Inventor: MAKINO FUMIO
IPC: B60T8/62
Filed: 1988-03-16
Granted: 1992-07-07
Abstract: ABSTRACT OF THE DISCLOSURE     An improved multiple control circuit is for use with an anti-lock brake control assembly. It includes a plurality of control logic circuits and an output decision circuit.  The control circuits simultaneously receive redundant sensor signals representative of wheel speeds and carry out logical operations based upon the input signals to simultaneously transmit redundant command signals to control the brake pressure of the wheels.  Such output signals are not directly sent to actuators, such as brake pressure control valve, but are instead sent through the output decision circuit.  If the command signals of the control circuits should be different for some reason, the output decision circuit selects and transmits to the actuators the command signals to control the automobile in the safest manner based upon AND logic and OR logic.  Each control circuit is connected to a comparator which compares the output signals of the control circuit with those of the output decision circuit.  If there is a discrepancy between the signals and if such a discrepancy persists for a predetermined period of time, a failsafe signal is produced to disable the anti-lock brake control system.

Granted: 1993-11-30
Abstract: REVERSE OSMOSIS APPARATUS Abstract of the Disclosure A reverse osmosis member cartridge unit 10 for a drinking-water purification system is disclosed.  The reverse osmosis membrane cartridge unit 10 includes a reverse osmosis membrane permeator 11 spirally wound on a central winding tube 12 and surrounded by an impermeable barrier layer 15 which is, in turn, surrounded by a spirally wound prefilter 16.  A postfilter 30 is placed centrally within the winding tube 12.  The cartridge unit 10 is designed for functional installation in a housing tube 44 fastened and sealed to a valve plate 45 at one end and closed by a removable end cap 46 at the other or outboard end.  Feed water enters the cartridge unit through an inlet port 48 in the valve plate 45 at an outer radius to pass lengthwise in prefilter 16. Prefiltered water returns lengthwise through the reverse osmosis permeator 11 to a waste-water outlet port 43 in the valve plate 45 at an intermediate radius.  Product water which has permeated through the membrane flows inwardly through holes 92 in the winding tube 12 and into a clearance space 40 surrounding a central postfilter 30.  After traveling to the outboard end in the clearance space, the permeate flows through the length of the postfilter 30 to e purified-water outlet port at an inner radius in the valve plate 45.  The reverse osmosis membrane cartridge 10 is axially removable from the housing tube 44 for ease of replacement of the cartridge unit 10 without disturbing any piping connections.

Abstract: ABSTRACT OF THE DISCLOSURE:           An apparatus for use in analyzing materials for ash content includes a walled chamber which retains microwave radiation therein, a source of microwave radiation, such as a magnetron, for radiating onto contents of such chamber, and an ashing furnace in the chamber which includes a heat resistant wall of low thermal conductivity, which is transmissive of microwave radiation, and a microwave absorptive material which is capable of being heated by microwave radiation to an ashing temperature.  The furnace includes a passageway through it for the entry into the furnace cavity of a gas, such as air, and for venting gas, such as combustion products, from the furnace cavity, and preferably also includes a removable trapezoidally shaped door in a front wall thereof, which, when the chamber door is open, is readily removable from the furnace by hand, without burning the operator's fingers, despite the high internal temperature in the furnace cavity.  Air flows through the chamber and around the furnace, helping to cool the exterior, of the furnace walls.  It is preferred that the operation of the furnace and the ashing temperature be controlled by a combination of a temperature sensor, preferably a thermocouple, and a control mechanism, which turns the magnetron on and off as the tempera-ture in the furnace cavity falls below or rises above a desired set temperature, respectively.           Although the invention relates to a combination microwave apparatus, including an ashing furnace within it, various components of the described apparatuses are considered to be individually novel, unobvious and useful, such as the ashing furnace, with the door structure thereof, and the ashing and analytical processes described also meet such criteria of patentability.

Abstract: ABSTRACT OF THE DISCLOSURE                PREPARATION OF POLYMER POLYOL         A novel family of fluid polymer/polyols is prepared from modified polyols.  The modified polyols are the reaction product obtained by reacting a silicon atom containing compound with an unmodified polyol, the silicon atom compound being one which has (a) at least olefinically unsaturated hydrocarbyl group and (b) at least one functional group which is reactable with the hydroxy groups on the polyol.  Examples of such silicon atom containing compounds include vinyltriethoxysilane and vinyltrimethoxysilane.  Modified polyols of the type described are particularly useful in the preparation of polymer/polyols containing high levels of polymer since they reduce the viscosity of the final polymer/polyol and decrease the tendency of the polymer/polyol to produce polymer sediment.  The polymer/polyols can be reacted with polyisocyanates to form polyurethanes with improved load-carrying properties.
