Abstract: ABSTRACT         A beverage cooling bath includes a refrigeration evaporator immersed in water for growing ice thereon, there being a beverage cooling coil disposed elsewhere in such water.  In order to control the refrigeration system in response to a need for or in response to a sufficiency of ice built up on the evaporator, there is provided a control for doing so which includes a motor-driven impeller that directs a flow of water through a tube extending along a freezing surface on the evaporator, the tube leading to a reservoir in which there is a sensing control responsive to the water level, the reservoir returning water to the bath.

Abstract: ABSTRACT            A wheel probe for use on a pipe inspection vehicle.  The wheel probe comprises a annular perspex outer rim with a polyurethane tyre mounted on a hub assembly which, with the hub, defines a fluid-tight chamber containing an acoustic coupling fluid.  A number of ultrasonic transducers are located inside the chamber and are positioned close to the inside circumferential surface of the rim.  The hub assembly is carried by a spring loaded carriage which is secured through which ultrasound will pass.  The wheel probe includes a guide wheel on each side.  The guide wheels are carried by the carriage but are moveable bodily relative to the centre of the hub assembly, and when deflected, they operate on the assembly to move the wheel probe to ensure that the outer rim of the wheel is correctly aligned relative to the pipe.  The wheel probe has a number of shields spaced around its periphery.  The gaps between the shields define operating "windows" through which the rim of the wheel probe projects to contact the pipe.  The shields are located close to the bore of the pipe so that if the probe encounters an obstruction the shield snags on the obstruction, is pulled between the rim and the pipe to lift the wheel over the obstruction, and turns on to the next operating "window".  Cam followers are provided to hold the shields in position.

Title: Electrical switch of the shorting or ignition killing  type
Inventor: GALLAGHER DAVID A
IPC: H01R13/70
Filed: 1978-08-08
Granted: 1981-08-11
Abstract: ABSTRACT OF THE DISCLOSURE This invention relates generally to electrical switches of the shorting or ignition killing type and, more particularly, to an improved electrical switch and connector assembly in which the switch terminals and connections thereto are isolated from the environment to insure reliable switch operation.  Electrical switches of the type used for momentarily shorting a pair of conductors, such as those used in an ignition system to stop or kill an engine, are well known.  In high moisture conditions, water or other detrimental substances often seep or otherwise find their way into the prior art switch assembly and cause corrosion of the switch ter-minals, resulting in a condition where the switch terminals cannot be short circuited when desired, or the switch terminals become intermittently or even per-manently short circuited to cause unintended engine shut off.  The present invention provides an integral elec-trical shorting switch and connector assembly having a pair of switch terminals each with a shorting end and an opposite contact end isolated from the environment.  A conductive member for operatiaely shorting the switch terminals is mounted to a flexible, water-impervious boot surrounding and sealing the shorting end of the switch terminals, and a connector plug with contacts forms two interference-fit seals at the contact end of the switch terminals.

Abstract: NOBLE METAL-REFRACTORY METAL ALLOYS      AND METHOD FOR MAKING                 ABSTRACT OF THE DISCLOSURE      Finely divided noble metal-refractory metal alloys and methods for making them are disclosed.  As catalysts these alloys have greater activity than a catalyst of the same unalloyed noble metal and may be advantageously used as electrodes for fuel cells particularly when supported.  The method for making supported catalysts involves a simple and inexpensive procedure for converting a supported, finely divided noble metal catalyst to the desired alloy.  In a preferred embodiment the process includes intimately con-tacting the supported noble metal catalyst with a finely divided refractory metal oxide, the metallic component of which is capable of enhancing the activity of the catalyst when alloyed therewith, and then heating to a sufficiently high temperature, preferably in a reducing atmosphere, to reduce the oxide and simultaneously form a finely divided, supported alloy of the noble metal and the metallic com-ponent of the oxide.

The blistering is achieved by having two foamable coatings on the web, the lower of which is sacrificed to produce the blistering in the upper.  In one method the lower coating is foamed the upper coating is then applied in its pre-foamed state, and then heated so that the lower coating is sacrificed and the upper coating is foamed and blistered.          In another method both coatings are applied in their unfoamed  state with the lower coating having a lower foaming temperature than that of the upper coating.          Both coatings are then heated together.   The lower coating foams and is then sacrificed.   The upper coating foams  and  blisters.

Abstract: ABSTRACT OF THE DISCLOSURE         A flood control arrangement for dishwashers in which the in-flow to the dishwasher tub from the water sup-ply line is automatically terminated in the event the tub water rises to a flood level.  The arrangement includes a sealing plunger disposed in a plunger body member housing in-stalled downstream of the water fill valve.  The sealing plunger tends to be moved to the sealing position by the line water pressure to shut off in-flow to the dishwasher but is blocked from movement to this position whenever the water level is below the flood level by the stem of a float posi-tioned in the dishwasher tub.  When the water level in the tub approaches the flood level, the float rises in the tub to a position whereat the float stem releases the sealing plunger to allow it to move to the sealing position and shut off further flow to the dishwasher.  The float stem either causes the sealing plunger to be tilted off a sealing face or prevents it from moving laterally in the line to the seal-ing position in order to produce the blocking action.

The method involves admnistering to the patient specially treated carcinomas cells until the tolerance of the patient to the cytostatic agent is improved, and then administering the cytostatic agent.  The special treatment of the cells involves culturing carcinoma  cells isolated from the patient, subjecting portions of the cultured cells to different cytostatic agents and observing the visible morphology    damage of each portion, selecting the most effective cytostatic agent and treating the remainder of the cultured cells with it until 30 to 70% of the cells remain intact but partially weakened, removing the cytostatic agent by washing and then suspending the cells in a physiologically acceptable fluid to form a pharmaceutical preparation.  The medical treatment outlined above employing such pharmaceutical preparation allows tumor cells to be treated without undue harm to the patient.
