Abstract: 1,163,726. Photographic light-sensitive silver halide materials. EASTMAN KODAK CO. Sept. 16, 1966 [Sept. 17, 1965], No. 41502/66. Heading G2C. A light-sensitive silver halide material, in which the emulsion contains at least 50 mole per cent of silver chloride, contains in the emulsion or an adjacent layer a water-soluble siliconcontaining block copolymer of polyoxypropylene and polyoxyethylene in which the main polymer chain contains up to 15% by weight of silicon atoms, the polyoxypropylene content of the copolymer has an average molecular weight of 800 to 3, 000 and the polyoxyethylene units constitute 10 to 70 % by weight of the copolymer. The polymers may be those obtained by reacting a dialkyl siloxane e. g. dimethyl siloxane with a compound of the formula:- where Y is an organic radical of valence x1, n and x are integers greater than 1 so that the polyoxypropylene content of the copolymer has a molecular weight of 800-3, 000, E is a polyoxyethylene chain and R is hydrogen, alkyl, alkyl carbonyl or aryl carbonyl. The emulsion may also contain onium salts such as N:N<1>-ethylenedioxymethylpyridinium perchlorate. The materials are lith materials of improved speed of development, contrast and dot-quality.

Title: A moulding press for producing threaded articles of a thermosetting material
IPC: B29D1/00
Filed: 1967-09-13
Abstract: 1,141,187. Moulding articles with internal and external screw threads. TAVANNES MACHINES CO. S.A. 13 Sept., 1967 [22 Sept., 1966], No. 41823/67. Heading B5A. A press for moulding articles of thermosetting material having internal and external coaxial screw threads of the same or different pitch comprises at least one mould having a central core and an outer casing carrying impressions of the internal and external threads respectively in which the central core and outer casing are relatively movable in an axial direction and press centering means are provided to hold the centre core coaxial with the outer casing during the pressing operation, this means being rendered inoperative during unscrewing of the article after pressing. As shown the screw threaded article D is moulded between a core die 26, outer casing 17 and bottom die 8 by pressure between the upper mould portion 1 and bottom mould portion 2. The core member comprises a top polygonal port 36 loosely located in bore 25 with a clearance of about 0À25 mm, a cylindrical portion 33 tightly but slidably fitting in collar 32 of bore 25, a threaded collar 30 and a head 28 for moulding a grooved middle portion of article D, this head being rotatably attached to the rest of the core. The article D is moulded with the mould as shown, the core being maintained in a position coaxial with the outer casing 17 by engagement of cylindrical portion 33 in collar 32. To extract the moulded sleeve, lower mould portion 2 is lowered withdrawing bottom die 8 from the article. Push rod 21 is lowered, forcing outer casing 17 downwards thereby lowering cylindrical core portion 33 out of collar 32. A rotatable key is then raised into contact with the base of head 28. Rotation of head 28 unscrews the article D from the outer casing 17 and at the same time unscrews the threaded collar 30 from the internal screw. Lateral movement of this collar due to a difference between the pitches of the two screws is taken up by the core 26 sliding in its bore 25 and lateral movement of the core due to differences in wall thickness of the article is possible as the core is no longer a tight fit in its bore 25.

Abstract: 1480816 Delivering cigarettes HAUNIWERKE KORBER & CO KG 26 Sept 1974 [27 Sept 1973] 41836/74 Heading A2C An arrangement for transferring cigarettes from a production machine to a processing machine 54 comprises a buffer store 33, a direct feed path 3 bypassing the buffer store and a switch 1 for selectively directing cigarettes into the buffer store or the direct feed path. The switch 1 consists of a supply conveyor 23, a discharge conveyor 61 supplying the buffer store, and a discharge conveyor 22 supplying the direct feed path. In the event of a breakdown in the processing machine 54 this is detected by a sensor 89 which stops two conveyors 76, 78 of the direct feed. path causing an accumulation of cigarettes at point 82 which is detected by a photoelectric cell 90. This in turn activates the conveyor 61 so that further cigarettes are transferred to the buffer store. If the production machines breaks down the lack of cigarettes on the supply conveyor 23 is detected by a photoelectric cell 88. This halts conveyors 78 of the direct feed path and a conveyor 83 of the buffer store. The lack of cigarettes joining the conveyor 76 allows a baffle plate 86 to swing outwardly to release cigarettes from the buffer store onto the conveyor 76.

The target may be made by a photo-resist process and each character may be accommodated within a square 200 x 200 microns in size. The silicon substrate is preferably doped with antimony sulphide to increase its conductivity and a small amount of antimony sulphide may be diffused into the oxide layer to increase its conductivity and thereby prevent accumulation of charge upon it when it is scanned by an electron beam. Alternatively, as illustrated in Fig. 3, the oxide layer may be divided up by a mosaic of lines 32 2 microns thick and 5 microns apart to prevent concentration of charge.

Title: Multiplex channel selector

Abstract: 997,992. Multiplex pulse signalling. STANDARD TELEPHONES & CABLES Ltd. Dec. 1, 1961 [Dec. 2, 1960], No. 43080/61. Heading H4L. In a receiver in a pulse time modulation time division multiplex system in which the number of channels and the frame period may be varied, e.g. to provide secrecy, means are provided at the receiver for selecting the frame synchronizing signal and obtaining a first signal proportional to the number of channels and a second signal proportional to the frame period, a train of equally spaced timing pulses being derived from the two signals. Receiver. A detector 8, Fig. 2, e.g. an integrator, detects the synchronizing signal, which may be a distinct pulse or pulse group and via an amplifier 10 a sawtooth generator 11 is triggered to provide a sawtooth wave having a maximum amplitude proportional to the time interval between adjacent synchronizing pulses i.e. the frame period, which is amplified at 12 to provide a sawtooth wave symmetrically disposed about a zero axis. This sawtooth wave is supplied to a peak detector 13 supplying positive and negative voltages proportional to the respective peaks of the sawtooth signal to a divider 5 including switches 14 and dividers and comparators 15, as shown, up to four channels being provided for. A counter 3 counts the channel pulses in a frame period to produce an output signal of amplitude proportional to the number of channels in a frame period, which is supplied to switches 14 to determine to which one of circuits 15 the output of circuit 13 is applied. Switches 14 may comprise a pair of diodes biased so that one conducts at a predetermined level to couple the output of circuit 13 to the appropriate circuits 15, the other remaining non-conducting until an increase in amplitude of the signal from 3 due to an increase in the number of channels will cause it to conduct and disconnect the circuit 13 from the previously selected circuit 15. Assuming that four channels are detected at 3 the output of circuit 13 will be passed to divider and comparator 15, which is also supplied with the sawtooth signal from 12, so that the sawtooth wave is divided into five equal parts for application to amplifier clippers 16 to 16d. Clippers 16 generate square wave pulses having a duration and polarity determined by the equal time intervals derived from divider 15 which are coupled to a common differentiator 17 to produce equally spaced channel signals for controlling the channel separator and demodulator 7. Transmitter. A generator 18 provides a signal whose repetition rate controls the frame period and is supplied to a source 19 which introduces the synchronizing signals. The output of generator 18 is coupled to any one of distributers 20 by means of one of the switches 21 selected manually or by an automatically programmed device by a device 22, and modulators 23 to 23d co-operate with respective modulating signal sources 24 to 24d, the number of modulators in use being dependent upon which of distributers 20 is selected.
