Filed: 1964-08-05
Abstract: 1,062,693. Photographic apparatus. INTERNATIONAL POLAROID CORPORATION. Aug.5, 1964 [Aug. 5, 1963], No. 31853/64. Heading G2A. In a camera in which processing liquid 44 is released and distributed between the layers of a multilayer film assembly 22 when this assembly is longitudinally advanced between the bite of compression-applying means (in this case rolls 18, 20), a plate 10 having a curved edge 10c is positioned adjacent the rolls so as to subject an area of the film to a non uniform bearing force just before it enters the rolls, the plate 10 thereby encouraging the liquid 44 to flow towards the sides of the film. Theplate is inclined with respect to a plane normal to the plane containing the rolls' axes, thus causing the centre portion of the edge 10c to exert a greater force on the film than do the outer portions, the centre portion being of greater radius than the outer portions. The longitudinal marginal areas of the film pass between clips Fig. 1 (not shown) and portions of a bar 32 and are thus held together to prevent the escape of the liquid 44 during the spreading operation. This causes the film to bulge at its centre, and a bearing member 38 is provided above the film to hold the film layers against undue separation. If the film is sufficiently rigid, member 38 may be omitted. The edge 10c may be located above or below the bite line of the rolls 18, 20 which are held apart by a flange 28 to provide a minimum spacing 29 through which the film passes.

IPC: F01D5/08
Filed: 1955-11-09
Abstract: 776,732. Gas turbines; liquid seals. GENERAL MOTORS CORPORATION. Nov. 9, 1955, No. 32022/55. Classes 110 (3) and 122 (5). A gas turbine rotor assembly comprises blades having internal coolant chambers, an annular coolant chamber concentric with the rotor, and tubes connecting the blade chambers with the annular chamber, whereby liquid coolant supplied to the annular chamber is distributed centrifugally to the blade chambers where it vaporizes. Water or other liquid coolant is passed through a conduit 24, Figs. 1, 2 and 4, and a rotary slinger 58 to an auxiliary wheel 56 mounted on the shaft of the turbine rotor 52, and thence through longitudinal passages 70 and radial passages 68 to an annular chamber 66 at the rim of the wheel 56. The coolant is transferred from the chamber 66 to the interiors of hollow rotor blades 54 by way of tubes 76, Figs. 2 and 6, which fit into skewed grooves 80 milled in the rear face of the wheel 56. Inlet holes 83 in the tubes 76 align with discharge holes 82 in the wheel 56. The tubes 76 are closed by plugs 78 which fit into an annular The coolant vaporized within the blades is displaced by the heavier incoming liquid coolant towards the centre of the wheel 56, and passes by way of a passage 14<SP>1</SP>, bellows 172 and 176 and a conduit 20 to a condenser 22, where it is cooled by, say, atmospheric air supplied by the ram effect of the motion of the aircraft. The condensed coolant is returned to the conduit 24 by a pump 108. The radial depth of the ring of liquid coolant in the chamber 66 is automatically maintained within limits by a valve 112 which is opened by a solenoid 128 and closed by a solenoid 120. A detent 124 holds the valve in either position. The solenoids are operated through relays 100 and 104 by the completion, by the electrically conductive liquid coolant, of circuits including depth-sensing electrodes 92, 94, Fig. 10. A valve 110, set manually to deliver less coolant than required, supplements the valve 112. Some of the coolant is fed through a conduit 138 to the annular space between a stationary disc 142 and a rotating member 140, to act as a sealing liquid. Blades 148 may be provided to ensure rotation of the sealing liquid. Excess sealing liquid is carried away with the vaporized coolant in the conduit 20. Cooling air from, say, the plant compressor is supplied through a conduit 48 to a cylindrical casing 40, and passes through the clearance between a disc 44 and the hub of the wheel 56 to flow over the rear face of the wheel.

Abstract: 1526920 Gamma camera systems SELO SOC ELETTRONICA LOMBARDA SpA 1 Aug 1977 [10 Aug 1976] 32234/77 Heading H4F A circuit for computing coordinate signals x, y from the signals emitted by the photosensors 11 of a gamma camera includes dynamic attenuators 19 whose attenuation is changed in accordance with changes in the intensity of the detected gamma radiation. The photosensors 11 feed a matrix 17 and a summing circuit 13. The matrix provides signals proportional both to the coordinates and the intensity of the radiation. The signals are fed via delays 18 to the attenuators 19. The output Ze of the summing circuit 13 is proportional to the intensity and feeds a comparator 15 and a pulse amplitude analyser 14. If Ze falls within a range selected S by the operator a store 16 passes a signal corresponding to that range to the attenuators in order to adjust the degree of attenuation. The attenuator outputs pass direct and via a summing circuit 21 to units 20 which form the ratio of their inputs to provide the coordinate signals. The use of the attenuators obviates the need for the ratio units 20 to have a large dynamic range.
