Abstract: 1,251,219. Cigar-making machines. IMPERIAL TOBACCO GROUP Ltd. 31 Oct., 1969 [6 Dec., 1968], No. 57985/68. Heading A2C. A transfer device 10 for transferring pieces of tobacco sheet 26 (or leaf) from a supply location to a rolling or wrapping location in a cigar-making machine, comprises a perforated suction plate 34 for securing the sheet 26 (or leaf) to the device 10, a paste roller 40 mounted adjacent one edge of the suction plate 34 for contact with the sheet 26 (or leaf) carried by the plate 34, means for supplying paste to the roller 40 and means for rotating the roller 40 to transfer paste to the sheet 26 (or leaf). A continuous reconstituted tobacco sheet 12 is intermittently fed from a reel 21 between plates 23, 24, and is cut off by a knife 25 to form a sheet 26 of sufficient length to form a single bunch binder. The perforated plate 34 forms one side of a suction chamber 33 which, together with a paste chamber 50 and bearings (41, 41') supporting the roller 40, is mounted ultimately to a cranked arm 11 for pivotal movement about a point (not shown) to transfer the sheet 26 held by the plate 34 through approximately 90‹ in the direction of the arrow 13 into a substantially horizontal position on a cigar bunch rolling apron (not shown). Paste is fed to the chamber 50 via flexible tubing 53. A knurled drive wheel (65) is connected via a clutch (66) to the shaft (64) of the roller 40 and this wheel (65), during the first part only of the pivoting movement of the device 10, engages an arcuate rolling surface 62 of a block 61 supported by an L-section bracket 60 and biassed upwardly by a leaf spring 63. Engagement of the wheel (65) with the surface 62 causes the roller 40 to rotate and to apply paste along a line across the cut-off sheet 26, in the area indicated by the arrow 70, until the wheel (65) runs off the end of the surface 62. As the sheet 26 is deposited on the rolling apron, suction is cut off from the chamber 33 and is applied to perforations in the apron to pull the sheet off the roller 40. On the return stroke of the device 11, the clutch (66) disconnects the driving wheel 65 from the roller 40 to prevent the latter from being rotated when the wheel 65 against contacts the surface 62.

Abstract: 1,256,724. Automatic exchange systems. SIEMENS A.G. 26 June, 1969 [27 June, 1968], No. 32251/69. Heading H4K. In a multi-exchange system in which every exchange contains "part-details" of a route to every subscriber in the system, arrival of a call at an exchange to which a subscriber was, but no longer is, attached causes the identity of the subscriber plus a code signal denoting for example the transmitting exchange's identity to be sent to the neighbouring exchanges and from there to further neighbouring exchanges 1 with the addition of further coded and so on until the new exchange to which the subscriber is attached is located, whereafter a path to the subscriber via his old terminating exchange is cut through. The referred to "part-details" comprise the identity of the firal neighbouring exchange from which the identity of a subscriber reaches a particular exchange when the subscriber causes his identity to be injected into the system from his parent exchange. As soon as an exchange has recorded the subscriber's identity and the neighbouring exchange's identity, it retransmits the subscriber's identity together with its own identity to its neighbours and ignores any further reception of subscriber and exchange identities in respect of this subscriber. When the first call, to a subscriber who has moved, occurs, the part details of routes to his new termination are inserted in the exchanges of the system by the method just outlined. If a plurality of routes between his old and new exchanges are found during the first call only one route is selected for use by the call. Interexchange signalling may be effected over speech or data links using PCM, TDM, FDM or MF techniques. A group of subscribers permanently connected to a PBX-like exchange may be moved en-bloc, such subscribers being identified in the exchanges of the system by the identity of their PBX.

Abstract: 1295912 Recording apparatus FABRIQUES DES MONTRES ZENITH S A 15 Jan 1970 [15 Jan 1969] 1931/70 Heading G1J A recording tachometer on a vehicle comprising a pendulum 12 reacting to unevenness of a road and carrying a component for marking a trace on a moving record support indicative of the time the vehicle is moving or stationary is provided with an electro-mechanical device capable of supplying mechanical impulses to the pendulum 12 in such a way as to produce an asymmetric displacement in relation to its rest position in response to current fed thereto by the vehicle generator. The electro-mechanical device may be a thermal relay or a motor. On a vehicle equipped with an alternator a small synchronous motor may apply impulses to the pendulum 12 through a cam 7 superimposing them over the oscillations due to unevenness on the road. When a battery driven micro-motor 1 is used it may be disconnected when the vehicle moves by using the speed recording rack to open a switch. The pendulum 12 is displaced to one side of its rest position by a cam engaging an arm 11 thereof. The cam 7 is free on the shaft 5 of motor 1 and has a pivot pin 8 which is drivingly engaged by a pin 6 in the motor shaft 5 and carries a pulley 15 to which a return spring 16 is secured. When the vehicle is not moving, energization of the electro-mechanical device produces a trace half the width of the "in motion" trace which may be indicative of the time the vehicle is working while stationary e.g. by operating a winch. The motor 1 may be disposed in various ways e.g. in the circuit of a tell-tale light. (For figures see next page)

Abstract: 1295989 Polyamide films UNITIKA KK 20 May 1970 [20 May 1969] 24478/70 Heading B5B  A process for the production of polyamide films having improved anti-blocking properties involves the extrusion of a molten synthetic linear polyamide, preferably of poly-#-caproamide, polyhexamethylene adipamide, polyhexamethylene sebacamide, poly - 11 - aminoundecanamide, polylaurinamide or copolymers of at least two of the monomers thereof, on to a cooling roller and simultaneously providing a layer of inert gas of predetermined thickness over the entire width of the film between the extruded film and the roller. The layer of gas may be provided by feeding the gas between the film and the roller at a pressure whereby no inflation of the film occurs or the layer of gas may be trapped by contact of the outer edges of the extruded film on the roller. The thickness of the layer may be adjusted by control of the angle between the tangent from the roller to the point of extrusion and the direction of extrusion of the molten film and by varying the distance between the roller and the point of extrusion. The surface of the roller may be embossed to facilitate the retention of air under the film. The effective thickness of the layer of gas is preferably in the range 50-150 microns and may be calculated using the formula where T, T 0  and T 1  are the temperatures of the cooling roller, the film at commencement of cooling on the roller, and the film at time t respectively; L# and c are the thickness of the extruded film, its density and specific heat respectively; k and x are the heat conductivity of the gas and the effective thickness of the layer of gas respectively and t is the time measured from the commencement of cooling by the cooling roller. In examples, polyamide films of varying thicknesses are produced by the process of the invention using gas layers of different thicknesses and differ - enttemperatures of extrusion and of the cooling roller. The films are then subjected to simultaneous drawing in the transverse and longitudinal directions in a hot air atmosphere at draw speeds of between 17,000 and 25,000%/ minute and temperatures of 120 or 130 C.
