Abstract: ABSTRACT     A method of heat treating a slurry material which has combustible and incombustible components includes burning the material in a fluidised bed, to devolatilise the water content and to produce a material which cannot be reslimed.  Fine material elutriated from the bed is separated from the entraining gases and is recycled to the centre axis of the bed such that upon rising through the bed they encounter and are doused by the incoming spray of slurry material.The fine material so introduced is at a temperature lower than that of the fluidised bed and thus can be used to control the bed temperature by varying the amount of fine material recycled.

Abstract: ABSTRACT OF THE DISCLOSURE The use of molecular sieve zeolite for the effective utilization of low-grade heat sources such as solar energy.  A system includes molecular sieve zeolite and a low pressure polar gaseous fluid adapted to be adsorbed by the zeolite which is in a closed container and circuit which includes a condenser and a gas expansion cooler member.  When the container is heated, a gas is given off from the zeolite, cooled in a condenser, and thereafter expanded for cooling purposes.  In one embodiment, the cooled gas is received in a further container having the zeolite therein and subsequently, upon cooling of the first container, the gaseous fluid may be returned thereto via again a condenser and gas expansion cooler member to provide further cooling. In another embodiment, zeolite is formed by sintering same to form a pressure resistant divider across the container.  One side of the divider is heated to create a temperature gradient across the divider which functions as a heat energized pump for the adsorbed gaseous fluid, a pressure as well as tempera-ture differential develops within the container across the divider whereupon the heated relatively pressurized gas, after giving up some of its energy in a circuit which may include a condenser and gas expansion member, is returned to the container to be again pressurized and heated by the action of the sintered zeolite divider.  In a further embodiment, water vapor is adsorbed from a zeolite panel by solar heat during the day and condensed by cooling, and collected in a container, and at night, at a lower relative pressure, it evaporates and is readsorbed by the zeolite panel whereupon ice is formed in the container which collects the water during the day.  In another embodi-ment, a solar heated liquid is circulated in series through heat exchangers in plurality of zeolite filled pressure vessels with intervening cooling coils for the liquid.  Nitrogen in one of the vessels is expelled at high pressure through an engine to be adsorbed by a cooler low pressure vessel with valving cycling which vessel is at high pressure and which is at low pressure.

Abstract: ABSTRACT OF THE DISCLOSURE           A wet-niche type lamp for providing underwater illumination in a swimming pool or the like includes an over-temperature protection circuit which interrupts the supply of electrical energy to the lamp when the level of the cooling water surrounding the lamp drops below a pre-determined level.  The circuit includes a thermistor mounted in an heat exchange relationship with the surrounding water so that heat energy generated in the thermistor, as a consequence of the current flow through it, is normally transferred to the surrounding water.  Should the level of the surrounding water drop below that of the thermistor, the thermistor heat energy quickly evaporates any remaining water film on the exterior surface of the thermistor to allow its temperature to rise.  The control circuit, in response to the temperature increase, interrupts the flow of electrical energy to the lamp to prevent over-temperature operation.

Abstract: ABSTRACT OF THE DISCLOSURE          A close-off valve for suction pipes to establish communication between a source of pressure and a consumer of pressure, such as a hydraulic pump. The valve makes it possible to disconnect the consumer in a simple and reliable manner, that is without leakage of the pressure, in addition to which it allows a liquid, such as oil, in certain quantities to flow through the valve above the valve disc, when the latter assumes the position in which it closes the outlet of the valve. For this purpose the valve comprises a solenoid valve which controls a flow of pressurized air to the valve housing in order to actuate the valve disc closing off said communication. In addition, the valve is arranged with through-passage means above said disc in order to allow passage-through of a certain amount of liquid, when the valve disc is in its closing position.

Abstract: Abstract of the Disclosure A programmable automatic controller for operating a section of a glassware forming machine having a plurality of components which operate in a timed or sequential relationship with one another.  The controller includes a timing means for generating cycle clock pulses in synchronism with the operation of the machine, wherein the cycle clock pulses provide an instantaneous indication of the time elapsed in each cycle of operation of the machine.  A random-access memory (RAM) stores the relative times during each cycle of machine operation when each of the plu-rality of machine components are to be enabled and/or inhibited. When the time elapsed in a cycle corresponds to a component actuating time stored in the running storage, an actuating sig-nal is generated by a comparator.  This signal is coupled to a machine component addressing arrangement which provides a compo-nent enable or inhibit command signal to the addressed component whose actuating time compared to the cycle time elapsed. Accordingly, in a cycle of operation a plurality of component operating command signals are generated which command the respective machine components to initiate and terminate opera-tion at preselected time intervals.    Means are provided for selectively varying the component actuating times stored in the RAM while the machine is stopped or in operation.    The controller is designed to operate directly next to the section it controls since its design employs a minimal number of components all able to function with a minimal amount of cooling.
