IPC: H01J5/24
Filed: 1937-01-28
Abstract: 470,375. Discharge apparatus. LORENZ AKT.-GES., C. Jan. 28, 1937, Nos. 2500 and 2501. Convention dates, Jan. 28, 1936 and March 4, 1936. [Class 39 (i)] [Also in Group XXXVI] In the manufacture of an electric discharge tube metal and ceramic parts are interconnected by seals in successive melting operations, the sealing material employed in the first operation having a higher melting point than that employed in the second melting operation. In one form the envelope comprises a pot 1, Fig. 1, and cover 3 of ceramic material sealed together at 10. Leads 4 ... 7 to the electrodes are taken through seals 20 .. 23 of material such as hard glass having a higher melting point than that of the seal 10. The melting of the seal 10 may then be carried out in a furnace without melting the previously made seals 20... 23. The cover may be grooved to receive the edge of the pot. The exhaust tube 8, integral with the cover, is closed with high melting point material; in a modification the tube 8 is a separate tube sealed into the cover by low-melting point material. In another form the anode 34, Fig. 2, with cooling fins 11, is sealed at each end to ceramic tubes 12, 13 provided with ceramic end plates 3, 14. The material of seals 10, 19 has a lower melting-point than that of previously-made seals 17, 18. The tapered flanges 16 on the anode may be shrunk onto the cylinders 12, 13, as described in Specification 975/37.

Abstract: 1,114,977. Television. SONY CORPORATION. 21 Jan., 1966 [23 Jan., 1965 (2)], No. 2878/66. Heading H4F. [Also in Division G5] In a video magnetic recording and playback system, the line (horizontal) and frame (vertical) synchronizing pulses are derived from pick offs actuated by magnetic elements driven with the video heads 4a, 4b. These heads are disposed at diametrically opposite positions on a motordriven disc 3 and co-operate with magnetic tape 5 as it is helically driven around a fixed cylindrical drum 7. The vertical synchronizing pulses are generated in a pick off coil 10 by diametrically opposed magnetic strips 8a, 8b on disc 3 and the horizontal synchronizing pulses are generated in two pick off coils 17 by the magnetic teeth 11 of a gear-wheel 12 which is driven with disc 3 by a motor 1. The outputs of coils 17 are combined in a mixer circuit 22 Fig. 3 (not shown), and the output obtained at terminal 18 applied through switch 8<SP>1</SP> to a horizontal synchronizing signal input terminal 25<SP>1</SP> of camera 19. The vertical and horizontal synchronizing signals may be recorded on the magnetic tape. If these signals are not recorded or their level is low or their waveform is distorted, the output of pick off coil 10 and that of mixer circuit 22 are applied respectively through switches 241, 81 to vertical and horizontal synchronizing signal input terminals 34, 35 of a television receiver 21 during playback.

Abstract: 1,215,295. Foamed coating. BRITISH INDUSTRIAL PLASTICS Ltd. 18 Jan., 1968 [19 Jan., 1967], No. 2887/67. Heading B2E, A surface is coated by applying thereto a urea-formaldehyde resin adhesive and subsequently applying a layer of incompletely cured, foamed aminoplastic resin and allowing the foam and adhesive to cure. In the case of a urea-formaldehyde foam, a urea-formaldehyde resin adhesive free from curing agent may be used and cure of the adhesive is brought about by curing agents in the foam. The adhesive may be allowed to dry before application of the foam to a state at which its adhesive quality can be restored by application of a suitable solvent which may be a component of the foam. The coating of the inside surface of a wall or ceiling of a building or of a surface of a structural panel of say wood or asbestos/concrete and concrete sheet is referred to. In example I a curing/foaming agent composition comprising water, resorcinol, phosphoric acid and a wetting agent was admixed with water, urea-formaldehyde resin and the mixture beaten to a foam. The foam was spread immediately using a spatula onto one surface of a wooden panel to which urea-formaldehyde solution free from curing agent had been applied shortly before application of the foam.
