Patent CA-1085635-A (CA)
Inventor: KEELING KERMIT B JR
IPC: F25D21/04

Granted: 1980-09-16
Abstract: ABSTRACT OF THE DISCLOSURE           An anti-sweat refrigerator cabinet warming device including a secondary refrigerant loop heat transfer arrangement extending through the refrigerator cabinet to warm those portions which have a tendency to form condensate on the exterior surfaces.  The secondary loop is warmed by thermal contact with the condenser loop of the refrigeration system, which thermal contact is selectively controllable by positioning of a control member to position a section of the secondary loop and the condenser loop into and out of thermal contact.  This is accomplished by a clamp acting on the loop sections, operated by a manual control lever to allow the power conservation when the warming of the cabinet is not required to prevent condensate formation.  The clamping device is designed to maximize the transfer of heat from the condenser loop section into the secondary loop section when the cabinet is being warmed.

Abstract: ABSTRACT     The invention relates to apparatus for breaking up vegetable matter, particularly to render such matter suitable for composting.  By increasing the exterior surface of organic materials through cutting,shredding and heating, more material can be exposed to decomposing bacteria.  The present invention is directed to the provision of apparatus of simple and efficient construction and may be embodied in forms which can fulfil a number of domestic needs.  According to the invention, an elliptical blade is mounted obliquely on a shaft such that it generates a cylinder as it rotates.  Vegetable matter is fed to one side of the cylinder, at which an edge is formed for shearing engagement with the rotating blade.  The material is not only broken up against this edge, but also swept across the cylinder by the blade for discharge at an opposite side.          The blade can also serve to beat the material as it passes across the cylinder.               The invention may be embodied in either a stationary or a mobile form.  In the former, the "cylinder" is normally positively defined by a drum having inlet and outlet openings in its cylindrical surface while in the latter, the cutting edge is conveniently formed on a plate extending around a part of the cylindrical surface to the point of discharge.

Abstract: ABSTRACT OF THE DISCLOSURE An electronic tachometer comprising an integrator having its output coupled to a variable gain amplifier and responsive to an input signal repre-sentative of the acceleration of a moveable load, such as a head assembly of a disk drive, for producing a coarse velocity signal at the output of the variable gain amplifier indicative of the load velocity, a tachometer gain correction circuit including another integrator coupled to receive the coarse velocity signal to produce a coarse distance signal indicative of distance traveled by the load and means for combining the coarse distance signal with a reference distance signal to produce a distance error signal which functions to adjust the gain of the variable gain amplifier so as to vary the course velocity signal to make the coarse distance signal equal to the reference distance signal, and accumulative error compensation means coupled to receive a gain indicative signal derived from the distance error signal to produce a signal input to the tachometer integrator which compensates for accumulative error in the tachometer output, whereby the tachometer accurately indicates load velocity.

Abstract: APPARATUS FOR DEINKING WASTE PAPER PULP           ABSTRACT OF THE DISCLOSURE           Apparatus for de-inking waste paper pulp using a foam flotation process in which the deinked slurry is to be recycles for the production of paper. The old paper is pulped (slushed), mixed with water and flotation- and other chemicals, to produce a slurry which is introduced into the flotation tank. Movement of the slurry through the flotation tank is achieved by the positioning of one or more water injector nozzles with air inlets which causes a swirling rotation from the injector towards a central outlet. Froth or foam bubbles float to the surface of the slurry carrying ink particles. A baffle plate leads the floated froth or foam and ink particles to a vacuum actuated outlet.

Abstract: VISCOSITY COMPENSATED FUEL    INJECTION SYSTEM                    ABSTRACT         An apparatus and method for supplying a pre-determined volume of liquid fuel (20) to a cylinder of a diesel engine (10) is provided.  A storage tank (22) stores a column of the liquid fuel (20) in a storage area (24).  A position sensor (36) transmits an analog signal proportional to the height of the fuel (20) in the tank (22).  A pressure transducer (32) disposed at the bottom of the storage area (24) transmits an analog signal corresponding to the static fluid pressure at the bottom of the storage area (24).  A temperature transducer (56) disposed along a fuel rail (16) trans-mits an analog temperature signal to an electronic fuel injection computer (14).  The computer (14) converts the analog height signal, the analog temperature signal and the analog pressure signal into digital values and mathematically divides the resulting digital values of height and pressure to obtain a digital value for the fuel density.  A programmed ROM (72) of the computer (14) produces an output binary signal representative of a predetermined viscosity based on the instantaneous values of the temperature and the density of the fuel (20) over a range of values of the density and the temperature. The ROM (72) generates a three-dimensional surface representing values of viscosity based upon the tempera-ture and the density.  The output binary signal of the ROM (72) is used by the computer (14) through a diesel output control (11) to control a metering solenoid (13) of a fuel injector (12) which injects fuel into a cylinder of the engine (10).

Abstract: ABSTRACT OF THE DISCLOSURE A wheel slip control circuit which utilizes conventional anti-skid control apparatus for automotive-type vehicles including an operator's brake valve, brake cylinders, wheel speed sensors, wheel behavior evaluation cir-cuitry and modulator valves to apply braking pressure to a sensed slipping wheel.  A solenoid-operated control valve in parallel with the brake valve between the system air reservoir and modulator valves is actuated via a push-button switch whenever the operator senses a slipping wheel during accelera-tion to connect reservoir air to the modulator valves.  The modulator valve of the slipping wheel is actuated by control signals emitted by the wheel behavior evaluation circuit to admit the reservoir air to pass to the brake cylinder of the slipping wheel to effect braking thereof.  The pressure sup-ply may be continuous or pulsed with or without a pressure-holding cycle.
