1,217,882. Refrigerating; heat pumps. F. W. CANTOR. 10 Jan., 1968 [10 Jan., 1967], No. 1543/68. Heading F4H. A refrigerator and/or heat pump comprises a rotor having conduits 37 attached thereto wherein a fluid having a relatively high initial pressure and density e.g. FREON gas, is rotated so as to move initially away from and then towards the axis of rotation in closed loops by a pump action utilizing the different densities and centrifugal forces of the fluid generated by a heat source and centrifugal action to pump the fluid through the conduits. The fluid may change between liquid and gaseous phases, be wholly gaseous or wholly liquid. In operation of the embodiment of Fig. 3, centrifugal force adiabatically compresses the fluid in a radial, insulated section 38 of each conduit, and in a following section 40 the fluid flows back towards the axis of the rotor and hot air is passed over fins 70 to expand the fluid isothermally with a lower density than in section 38. A following, radial insulated section 42 provides additional adiabatic expansion. The sections 38, 40, 42, therefore, comprise a heat pump. A following refrigerating and/or heating section comprises a section 44 extending parallel to the rotational axis of the rotor, an outwardly extending section 46 and radially inwardly projecting section 48 and a final section 50 extending towards the axis at an acute angle which comminicates with the central shaft or conduit 32 of the rotor. Section 44 is insulated to provide adiabatic expansion and the fluid in section 46 is compressed but cooled by heat transfer to ambient atmosphere by an air flow guidance means 78 and fins 84 so as to maintain the temperature of the fluid substantially constant.. The fluid thereafter is expanded adiabatically in insulated section 48 to a lower temperature and pressure, expanded isothermally in section 50 by extraction of heat from ambient atmosphere via a housing 87 and bladed fins 90 push cold air 94 forwardly. As described, the fluid, radii and rotational speed are selected so as not to liquefy. In modifications, Figs. 4, 5 and 8 (not shown), the refrigerant gas is selected to liquefy at chosen temperatures and pressures and the conduits have liquid reservoirs which are mounted in sections corresponding to sections 40, 46, 50. Reservoirs in sections corresponding to the sections 46, 48 are joined by an expansion nozzle. In a further modification, Fig. 9 (not shown), the section corresponding to section 48 is elongated parallel to the rotor axis and has thermally conductive, radially mounted washers separated from one another by insulation material to enhance isothermal expansion in the section 50.
Abstract:
A matrix-form radiation detector, operating in the proportional gas mode, is provided for indicating the x and y coordinates of each ionizing event caused by the radiation. This information is utilized to form an image of the radiation pattern being detected. The detector has a plurality of cathodes arranged in columns and rows. The cathodes in each column are connected to one another, and those in each row are electrically isolated from one another. A plurality of anode wires is provided. Each cathode substantially encircles one of the anode wires, and each wire passes through all of the cathodes in a given row. Encoding circuitry and other means are provided for encoding the address of each ionizing event, and for storing and/or displaying the encoded information.
Abstract:
AMMONIA AND WATER ARE ROTATED IN A ROTARY ENCLOSURE. AMMONIA GAS IS DRIVENOUT OF THE WATER. DIFFERENTIAL ACTION OF THE CENTRIFUGAL FORCE ON THE LIQUID AND THE GAS IS USED TO TRANSPORT THE GAS AND WATER WITHOUT USE OF A MECHANICAL PUMP. THE GAS AND THE WATER ARE PUMPED THROUGH THE ROTOR TOGETHER. WITH THE GAS FLOW AIDING IN PUMPING THE LIQUID.
