Patent GB-1217882-A (GB)
Title: Thermodynamic apparatus and process
Inventor: KANTOR FREDERICK W
IPC: F01K11/04
Filed: 1968-01-10
Abstract: 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.

Title: Improvements relating to vibration recording apparatus
IPC: G11B7/00
Filed: 1929-01-23
Abstract: 304,672. British Thomson-Houston Co., Ltd., (Assignees of Kellogg, E. W.). Jan. 23, 1928, [Convention date.]. Photographic recorders.-Apparatus for photographically recording vibrations, more particularly sound, on a moving sensitized member such as a film, comprises a screen arranged in the path of a beam of light which is directed on to the film and is vibrated in the direction of movement of the film, the screen having an edge so inclined as to produce a wedge-shaped formation of the beam. A narrow slit arranged substantially at right angles to the direction of travel of the film is so placed that the point of intersection with it of the inclined edge of the beam vibrates along the length of the slit. In the construction shown, a sound-influenced mirror 11 is supported by horizontal wires carrying currents in a magnetic field, the mirror reflecting light from a lamp 6 on to a vertically moving photographic film 1. Light from the source is intercepted before reaching the mirror by a screen having an opening 8 with an edge inclined as shown, the screen being preferably placed between two lenses 7, 10. After reflection, the beam passes through a lens 13 whereby an image of the opening 8 is formed on a second screen 15 having an horizontal slit 14, this slit making an acute angle with the inclined edge of the image. Adjustment is made so that when the mirror is at rest, approximately one half of the slit 14 is illuminated, and as the mirror vibrates, the length of the illuminated portion varies. An optical system 16 such as a microscope objective forms a much reduced image of the slit on the film 1. Thus a sound' record 28 of the kind shown in Fig. 3 (which represents a portion of a combined sound and picture record) is produced. The mirror and the lens 16 are generally placed at conjugate focal distances from the lens 13. This lens may be placed on either side of the screen 15, but is preferably arranged as shown. To facilitate focusing the image of the slit 14 on the film, an enlarged image of the line of light on the film may be formed on a ground glass screen 26 by using a thin piece of glass 25 arranged in the path of the beam at an angle of 45‹ so as to reflect on to the screen 26 a small proportion of the light passing back through the lens system 16. An eyepiece lens may be used instead of the ground glass screen. Specifications 180,296 and 207,178 are referred to.

[Class 98 (ii)] Diazotype printing-papers are dusted or coated with a finely powdered agent which is rubbed under pressure to form a film on the sensitive surface as distinct from a layer of powder, the surface being given a sheen or polish and being capable of holding other agents applied to the surface. Substances which form such a film are alkaline salts of the fatty acids, e.g. dry soaps, Pulv. Sapo. Durus B.P. ; Pulv. Sapo Animalis B.P. ; Pulv. coconut oil soap; and finely powdered waxy substances, e.g. carnauba wax, stearic acid. After application of the powder, the surface is rubbed under pressure as by a felt-covered weight and the excess powder removed, e.g. by fast rotating brushes. Coupling accelerating agents such as inorganic carbonates or oxides and coupling agents, e.g. arylide of 2 : 3 oxynaphthoic acid may be included in the dusting powder. The powdered soaps themselves act also as coupling accelerating agents. Stabilizing agents such as stearic, palmitic, &c. acids containing 10 per cent paraffin wax may be applied to the treated paper, and waterproofing agents as described in Specification 418,976 and 425,030, oil proofing agents as described in Specification 424,976, insecticides such as chloro - naphthalene derivatives.. background tinting agents such as leuco esters or vat dyestuffs, and translucing agents as described in Specification 425,215, [Group VIII], may also be applied individually or successively to the paper.
