Title: Improvements in the synchronising of television apparatus
IPC: H04N5/06
Filed: 1934-02-26
Abstract: 434,278. Television. RADIOAKT.- GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. Feb. 26, 1934, No. 6149. Convention date, Feb. 25, 1933. [Class 40 (iii)] Synchronizing impulses are transmitted on the same carrier as the picture signals, and no picture signals are transmitted during the transmission of synchronizing signals. The synchronizing signals are produced optically by a clear margin on a film with a picture of less width than the aperture spacing of a scanning disc. The clear margin is strongly illuminated by an appropriately shaped beam of light. The film with the light margin may be projected on the scanning disc on a slightly reduced scale so that the total area corresponds with the normal area of the film. The Specification as open to inspection under Sect. 91 also describes producing the synchronizing signal by a gas-discharge tube as described in Specification 431,521. Whena separate photo-electric cell 25 is used for generating the synchronizing signals, the latter control, directly or through tuned circuits, a gas-discharge tube 31 with a parallel condenser which short-circuits the picturesignal amplifier 27, during the transmission of synchronizing signals. A rotary switch may be used instead of the gas discharge tube. This subject-matter does not appear in the Specification as accepted.

Title: Process for the recovery of bromine
IPC: C01B7/09
Filed: 1932-03-01
Abstract: Bromine is expelled from solutions containing it in a free state by the passage of air or other indifferent gas therethrough, the liquid being heated to near the boiling point of bromine; alternatively, the removal may be effected at reduced pressure or by a combination of both methods.  Separation from the air &c. may be effected by cooling to the solidification point of bromine, by converting into iron bromide by passage through iron filings, by absorption in caustic alkalies, or by conversion into hydrogen bromide by passage over brown coal.  Purification from the chlorine originally used for displacing the bromine may be effected in known manner by passing the crude bromine or the bromine-air mixture through a bromide solution or by heating the crude bromine to just below its boiling point when the chlorine is expelled.

Title: Improvements relating to the locking of nuts and other screwed articles on to screw threads
Filed: 1942-05-08
Abstract: 553,936. Locking nuts. WOOD, G. May 8, 1942, No. 6230. [Class 89 (i)] A nut 1 and locking member 5 are tapped to suit the bolt at 4 and 11 and the upper part of the nut 1 is turned down and threaded to suit an internal thread 6 in a counterbored part of the nut 5. The threads 4 and 6 differ in pitch. Clearance grooves are provided at 7 and 8 and, after assembly, the end of the thread 6 in the groove 8 is deformed to prevent separation of the nuts. The deformed part may merge into the normal thread, or a radial cut may be made so that the deformed section starts with an abrupt displacement. Part of the thread on the other nut may be cut away to leave a square end that abuts positively against the displaced section. The under face of the nut 5 may be concave at 25, Fig. 5, to facilitate the deformation by a tool introduced between the nuts.

When the stops S are moved to release the batches, the latter are advanced by belts 17, 21 on to hinged guide flaps 33, 34, Figs. 2 and 3, and against front stops 35, 36. The flaps are then swung to vertical position to combine the batches B into a vertically oriented stack P on a conveyer 37 which, when the stops 35, 36 releases the stack, carries it to a further operating station. Top and bottom covers may be fed laterally on to the flaps before the batches are received, or a single cover comprising top and bottom parts and a spine is fed laterally on to the flaps and conveyer 37. The web may be replaced by a plurality of superposed webs, so that each cut item is a plurality of sheets. In another form, Fig. 4, the flaps 33<SP>1</SP>, 34<SP>1</SP> are initially inclined in V-form, having horizontal flanges 33b, whereby the batches B and covers are tilted into the V and rest on the conveyer 37 when the flaps are moved to vertical position about hinges 39.

Abstract: 949,866. Refrigerating. CARRIER CORPORATION. Feb. 23, 1961, [March 2, 1960(2)], No. 6677/61. Heading F4H. In a continuous cycle absorption system using a saline solution as the absorbent and the solvent as the refrigerant in which precipitation of salt occurs in the generator at reduced loads as described in Specification 929.148, the generator is heated by hot liquid, e.g. water, the supply of which is regulated. As shown, strong solution from the generator flows to pipe 17 over overflow arrangement 16 and contacts a thermal bulb 64 actuating valve 61 in the heating water supply pipe 55. At very low or zero loads, no solution may leave the generator and the spent heating water leaving tubes 8 through pipe 60 will increase in temperature. This is detected by thermal bulb 81 which takes over control of valve 61 from bulb 64 and prevents overheating of the generator. In a modification, Fig. 3 (not shown), bulb 64 is responsive to the temperature of spent heating water and the temperature of the supplied heating water is kept constant. Specification 787,298 also is referred to.
