Patent CA-1144624-A (CA)
Inventor: OPPERUD HANS-JOERGEN
IPC: F16H61/68
Filed: 1982-02-17
Granted: 1983-04-12
Abstract: The invention relates to a control system for controlling a power transmission device arranged between a driving engine and a drive axle of a vehicle and comprising a torque converter and an automatic step gearbox. The gearbox is equipped with an electric control device having a microcomputer, which device permits the operator to select, by means of a selector lever, the desired driving direction of the vehicle even if it is moving in the opposite direction to the desired direction. When a directional command signal is sent to the control device, reversing gear control means therein reverse the working direction of the gearbox so that the gearbox works in the opposite direction to the driving direction. First gear can be obtained by manually operating the selector lever to cause a forced downshift signal to be sent to drive gear control means, provided the vehicle speed is within the working range of second gear. The control system of the invention is particularly suitable for use in construction vehicles such as wheeled loaders.

Abstract: APPARATUS FOR COOLING A BODY                 ABSTRACT OF THE DISCLOSURE     The present invention relates to apparatus for cooling an object which is exposed to high temperatures and particularly to cooling by heat transfer to a liquid.          According to the invention an internal hose is disposed in a fluid conduit.  The hose is permeable to the coolant liquid which is circulated therein so that there is created a substantially stagnant fluid boundary layer between the walls of the tube and the internal hose for efficient heat transfer to the circulating fluid within the hose.

Abstract: Abstract A cable television up-down tuner includes a first frequency up conversion stage in which a first local oscillator, tunable over a wide frequency range, is coupled to a ring diode mixer having individual biasing networks in series with each diode.  A combination high pass and low pass filter provides a bandwidth coupling of input signals to the mixer.  An intermediate frequency amplifier couples the up converted signal to a second mixes.  A fixed tuned second local oscillator down con-verts the intermediate frequency signal to a selected television channel frequency.  The first local oscillator includes a printed circuit board transmission line resonator which is tuned by a varactor diode.  The two local oscillators are positioned adjacent the corners of a quadrilateral housing and are isolated from each other by three wall-type shields.

Abstract: OIL EQUALIZATION SYSTEM FOR PARALLEL CONNECTED COMPRESSORS                 ABSTRACT OF THE DISCLOSURE Parallel connected compressors are provided with an oil management scheme in which an oil equalization port on one compressor is connected via an oil return solenoid operated valve within a small diameter line to an injection port of a second compressor, and vice versa.  When the oil level in one compressor drops to a level sensed by an oil float switch, the oil float switch changes state, the oil return solenoid operated valve  is  opened,  feeding  its  injection  port  and energizing a one minute on delay timer.  Failure of the oil float switch to reset itself causes the com-pressor to go off on oil failure, and the oil return solenoid operated valve is closed.  If the oil float switch resets  itself at  any time  during the first minute, upon resetting,  an off delay timer is energ-ized to keep the oil return solenoid operated valve open  for  an  additional minute,  and the  compressor continues to operate.

Abstract: Abstract of the Disclosure A virtual storage system for use in conjunction with a host computer is disclosed.  The system features a memory control processor external to the host computer which divides user sized data files into blocks of a size con-venient for storage on, e.g., magnetic media and individually assigns these blocks to locations determined external to the host.  In this way, the extent of a particular data file is not specified by the user nor is empty space allocated to future use.  The virtual memory system may additionally comprise a high speed cache memory for receiving data written to the memory system at high speed from the host and for supplying memory data at high speed to the host, thus improving system performance.  Data compression and decompression may be incorporated in the storage system.  Numerous data back up and automated recovery processing operations may additionally be performed by this system without specific instruction from the host.

Abstract: SYNTHETIC PLASTIC PIPE COUPLING AND METHOD OF ASSEMBLY            ABSTRACT OF THE DISCLOSURE         A synthetic plastic pipe coupling comprising an in-ternally threaded fitting of synthetic plastic material and a pipe of synthetic plastic material.  The material of the fitting is harder than the material of the pipe so that the threads of the fitting act  as a die for the creation of helical grooves on the pipe as the pipe is hand screwed into the fitting.  The pipe is continued to be screwed passing the threaded portion of the fitting to a cylindrical portion adjacent to the threaded portion, which has a diameter not greater than the internal diameter of the threaded portion, so that the initial grooves are erased and the pipe is compressed to a lesser diameter for the purpose of creating a fluid tight contact zone operating hydraulically in favor of pressure and proportionately to it.

Abstract: Abstract of the Disclosure The invention relates to a method for recovering useable products from waste products deriving from the manufacture of aluminium fluoride on the basis of aluminium hydroxide and fluosilicic acid.  Mother liquors and washing water from a scrubber in said process, which solutions contain aluminium, silica, fluorine, and phosphorous are reacted in a first step with sodium ions at pH 2-3, and a temperature of 50-100°C to give a precipitate of sodium fluoro-aluminate, which is isolated.  The filtrate from said first step can be reacted with the silica waste product obtained in the above mentioned aluminium fluoride manufacture.  The method thus enables recovery of useful and valuable products from what would otherwise be waste material and thus also reduces environmental problems caused by the waste material.

Abstract: SELF-ALIGNING MASK                  ABSTRACT OF THE DISCLOSURE    A process for forming a self aligned resist mask over a surface of an alumina ceramic substrate having a conductive molybdenum pattern at said surface by first blanket  coating the surface with a negative resist  sensitive  to  aluminum  emitting  X-rays.   A blanket dosing of the substrate with resist insensi-tive X-rays occurs to induce X-ray emission by the aluminum of said substrate to penetrate said resist.          The  aluminum  X-ray  emission  is screened  by  said molybdenum  pattern  at  the  surface  and  the  resist adjacent the surface molybdenum pattern is penetrated by the aluminum X-ray emission.  The resist is devel-oped for removal thereof over the molybdenum pattern while  retaining the resist doped by said aluminum X-ray emission.  Further metalization can be accom-plished by evaporation or sputtering to blanket coat the developed resist with a conductive metal followed by  removal  of  the  resist with  the  metal  coating thereon such that the metal coating is retained on the molybdenum pattern.
