Patent GB-1320062-A (GB)
Title: Information storage tube and method of production
IPC: H01J29/41
Filed: 1971-04-19
Abstract: 1320062 Cathode-ray storage tubes RCA CORPORATION 19 April 1971 [2 Feb 1970] 20857/71 Heading H1D A method of making a target for a storage tube comprising the steps of mounting the periphery of a conductive metal film or mesh to a supporting frame; spreading a polymeric dielectric material as a thin layer over the film or mesh; and heating the target thus formed to dry and cure the polymeric material to a polymerized hard layer. The preferred construction comprises a mesh 40 with for example 1000 lines/inch attached by welding, brazing or cement to a metallic or insulating support ring 44. A polymeric material preferably an aromatic polyamide, or alternatively polyquinoxaline, polybenzoxazole, polybenzimidazole or polyphenylene sulphide with good secondary electron emission characteristics is deposited in an incompletely polymerized state on the mesh 40 which is placed on a spinning turntable such that the polymer spreads to a desired thickness. Spreading of the polymer is controlled by adjusting the solution concentration and hence the viscosity. After coating, the target is dried at 180‹ F. for 3 mins. A polyimide target is cured by first heating at 180‹ F. for 3 minutes, then at 400‹ F. for 2 hours, and finally at 750‹ F. for 10 mins. The input signal to be stored is applied to electrode 18 of electron gun 14, the reading and writing modes being effected by the same electron beam. In the read mode the electron beam discharges the target thereby producing a sequence of pulses on mesh 40 which drives the control grid of a viewing tube 54. The metallic mesh may be replaced by a thin imperforate metal film and alternatively the electron beam may scan the side of the target remote from the metal film. Photoelectrons from a photocathode may be used for writing and an electron gun beam for reading.

Abstract: 668,616. Washing-machines. BRITISH THOMSON-HOUSTON CO., Ltd., Aug. 23, 1950 [Sept. 1, 1949], No. 20891/50. Class 138 (ii). A clothes-washing machine provided with a receptacle and having water inlet means 18, comprises a combined soap container and water conduit 10 fixed relatively to the receptacle through which the same may be filled to a desired level, a chamber 15 of relatively large floor area and depth and a U-trap 16 communicating between the chamber and the receptacle means 21 accessible externally of the washing- machine to receive soap powder or the like and deposit the same within the chamber 15 remote from the entrance to the trap; and a pair of spouts 7, 8 for discharging water into the chamber for passage through the trap into the receptacle, one of the spouts 7 reaching over the pile of deposited soap powder 25 to discharge substantially directly into the trap with minimum pick-up of soap powder and the second discharging into the soap pile 25 to create a turbulent mixture of soap and water for passage into the receptacle. In the arrangement shown, as applied to a washing-machine of the type disclosed in Specification 636,104, the combined soap and water conduit 10 is of moulded rubber or the like and is mounted directly on the wall of the receptacle. Water is discharged from either or both cold and hot water spouts 7, 8 by solenoid-controlled valves 3, 4 respectively. The hot water spout 8 is formed with a flat nozzle portion to direct water over the width of the chamber 15 and both spouts are above the maximum overflow level of the chamber. In a modification, Fig. 3 (not shown), in which water is introduced into a basket within the machine the inlet 18 is extended over the rim of the basket by means of a suitable nozzle fixed to the wall of the receptacle. Specification 648,143 also is referred to.

Title: Apparatus for generating shock waves
IPC: G01V1/133
Filed: 1974-05-10
Abstract: 1470235 Seismic energy generators SOC POUR LE DEVELOPPEMENT DE LA RECHERCHE APPLIQUEE and CENTRE NATIONAL POUR L'EXPLOITATION DES OCEANS 10 May 1974 20894/74 Heading G1G A marine seismic energy generator, operating by creating a cavitation void behind a high velocity slug of liquid, is characterized in that the slug is ejected from the open end of a tube by a piston, the other end of the tube being closed by a propulsion unit for the piston. In the Fig. 2 embodiment compressed air or vapour, admitted to chamber 108 through conduit 114, forces down piston 104 when valve 111 is opened, to eject water from the open end 102 of tube 101. A vent 110 allows hydrostatic pressure to return the piston to its upper position. An aperture 115 in the piston introduces a controlled quantity of gas into the cavitation void to cushion the rebound of water imploding into the cavitation void, thereby avoiding undesired secondary shock wave production. Different diameter tubes 101 may be used to alter the primary shock wave power. In a second embodiment Fig. 1, (not shown) valve 111 is omitted and piston 104 is propelled by creating an electric arc between electrodes in water or in an explosive mixture in chamber 108.

[Class 96] [Also in Groups XVI and XXIX] A hydraulic drive for the sections A, B, C of a paper-making machine which are to be driven at proportional speeds, includes a plurality of pumps 4a ... 4c, in series with hydraulic motors 6a ... 6c, so that pump 4a drives motor 6a, the outlet of which leads to the inlet of pump 4b driving motor 6b and so on, the outlet of motor 6c being connected by a pipe 12a to the inlet of pump 4c, and at least one of the pumps 4b, 4c has means varying its displacement in response to variations in the rate at which liquid is delivered thereto. The pumps 4a ... 4c are driven by electric motors 5a ... 5c, and the hydraulic motors 6a ... 6c are shown driving through reduction gearing 8a ... 8c, the rollers 1 ... 3 of a paper-making machine. The displacement of pump 4a is controlled by a mechanism 16a, which may be operated electrically, and the pumps 4b, 4c are controlled by slide blocks 17b, 17c, urged towards zero displacement and adjusted by servomotors 18b, 19b and 18c, 19c respectively controlled by the pressure in pipes 12b, 12c. If the device 16a is adjusted to increase the displacement of pump 4a, the consequent rise in pressure in pipe 12b actuates servomotor 19b to increase the displacement of pump 4b, which similarly causes adjustment of the pump 4c. Loss of liquid in the circuit is replenished by a continuously running gear pump 34, and valves 9a ... 9c are provided between the sections, each of which when depressed byepass the motor of the corresponding section and connects the outlet of its respective pump directly to the inlet of the pump in the next section. Control pumps 40b, 40c may be operated to increase or decrease the amount of liquid flowing to the pumps 4b, 4c, thus increasing their displacements and varying the ratio of the speeds of the rollers 1 ... 3. When the pump 40b is connected as shown in Fig. 1, operation thereof adjusts both pumps 4b and 4c. Alternatively the inlet 43b may be connected to pipe 11b, when operation of pump 40b only adjusts the pump 4b.
