Title: Sound film apparatus
IPC: G03B31/02
Filed: 1964-07-28
Abstract: 1,072,802. Film drive mechanisms. A. W. KINGSTON. July 22, 1965 [July 28, 1964; Oct. 20, 1964], Nos. 30000/64 and 42805/64. Heading G5R. [Also in Division G2] A film traction mechanism for use with the projection of cine films with magnetic sound tracks comprises a reversible motor 47 driving film sprocket 17 through a resilient coupling, and film capstan 24 through peripheral frictional engagement between an idler wheel and driving shaft 48, the peripheral speed of the capstan being higher than that of the sprocket so that the film is tensioned, the difference in speed being taken up by slip between the wheel and the shaft. The resilient coupling consists of a disc 76 on the end of the sprocket shaft 78 with two diametrically opposite pegs which are interconnected by four springs with two similar pegs on gear 75 driven by motor 47 through worm gears and a toothed belt and pulleys. The motor also drives, through a similar coupling, the rotating apertured disc shutter 44, and the cam-operated claw feed (32) of Fig. 1 (not shown). This mechanism is carried in a deck (11) on which a cassette (10) is placed, the film being carried on reels (13, 14) which are driven by separately energized motors (45, 46), as in Fig. 2 (not shown), through clutches for forward or reverse film motion. The cassette takes doublerun film and contains the sprocket, capstan (24) with pressure roller (25) and edge guide (26) on a pivoting lever (29) and rollers (20, 21) with guides (19) to hold the film straight across opening (22) which receives the sound head (23) as described in 9242/64. A second opening (27) in the cassette receives a reflector (28) which directs light from lamp 34 through projection lens (39) for subsequent reflection on to a rear projection screen. An electromagnetic brake (61) is mounted on shaft (60), as in Fig. 2 (not shown), which drives a cross-shaft (62) carrying a contact drum (63) engaging two sets of contacts (64, 65) in the circuits of clutch (54) and brake (61) as in Fig. 2 (not shown). Brake (61) is by this means operated when claw (32) disengages from the film. The forward and reverse switch is biased to a neutral position and is held in the forward position by a solenoid which is de-energized automatically at the end of the film run when a metal foil on the film completes a circuit. A heat filter of glass with one ground face is used for prolonged projection of single frames, while the lamp unit may include a dichroic mirror at 28. Brake block (102) holds the sprocket (17), as in Fig. 1 (not shown), when the cassette is removed from the deck.

Title: Barbed-wire machine
IPC: B21F25/00
Filed: 1975-07-17
Abstract: 1461719 Making barbed wire; rolling; shearing AMERICAN ENG CO Ltd 17 July 1975 30097/75 Headings B3E B3A B3M and B3W In a barbed-wire making machine, a single wire on which barbs are to be wound is deformed by rolls, passes round a first idler pulley, through the barb winding head, and round a second idler pulley, the two pulleys being reciprocated intermittently so as to render the wire stationary at the winding head while the barbs are being wound. Fig. 1 shows the outside of a housing 1, 2, 3, 4, 5 on which the various rolls, pulleys, and winding head 27 are mounted, while Fig. 3 shows a reverse view inside the housing. A main shaft 12 is driven by motor 8, and drives the wire deforming rolls 19, 24 through chain drive 17. One roll drive shaft has universal joints to permit relative movement between the rolls. The rolls have alternative pairs of coacting circumferential grooves and are urged together by a spring, to deform the wire to an oval crosssection 121, Fig. 9, except at pairs of spaced points 120 which remain circular, defining between them a portion 121 on which barbs will be wound, whereby the barbs can neither slide along the wire, nor rotate on it. The wire passes over additional idler pulleys 122, 63, the latter driven from shaft 12 by drive 58 to prevent slack, and is taken up on spool 66 driven from shaft 12 through a slipping clutch. A winding guide pulley 123 may be reciprocated along its shaft by mechanism 124, 125. A cam 30 on shaft 12 oscillates a lever 32 connected to bar 34 supported on parallel arms 37, 41 secured to shafts 38, 42. Outside the housing, these shafts support the idler pulleys 28, 29 on arms 38, 43, to effect the required reciprocation of the pulleys. Arm 37 also operates a ratchet mechanism 46, 47, 48 by link 45, intermittently rotating shaft 49 which by drives 52, 53 rotates roll pairs 93, Fig. 5, causing intermittent advance of barb -forming wires 91. Shaft 12 also operates the winding head drive, which rotates the head 85, and drives a cam mechanism which causes periodic advance and retreat of the winding head as required. Shaft 12 also drives an eccentric mechanism causing timed advance of movable blades 110 to shear the wires 91, after which the barbed wire can be advanced through the head.

IPC: H04Q3/42
Filed: 1963-07-31
Abstract: 970,608. Electronic toggle data stores.  AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. July 31, 1963, No. 30338/63. Heading G4C. [Also in Division H3]  A circuit comprises data-storage toggles TOG1, TOG2 ... (comprising cross-coupled pairs of transistors) controlled through transistor gates T7, T1O . ., in which the transistors of the storage toggles and gates are cut-off in the quiescent state of the circuit, reception by the circuit of a seize signal SS first rendering the "O" side transistors T9, T12 . . of the toggles conducting and then allowing those toggles whose gates are receiving "1" information signals (at L1, L2 ...) to be switched to the "1"state. Referring to the drawing, in the quiescent state only the transistors T2, T3 are conducting, the latter weakly. Reception of a negative 300 Ás seize signal SS switches a control toggle TOGC (comprising transistors T1, T2) so T2 is cut-off. Consequently T3 conducts strongly and T4 conducts. This effectively earths the line R, making the "O" side transistors T9, T22... of the storage toggles conduct. In addition condenser C2 discharges via resistor R12 and after 100 Ás it has discharged sufficiently to make transistor T5 conduct which (a) primes the " 1" side transistors T8, T11 . . . (over line S) and (b) makes transistor T6 conduct to prime the gates T7, T10 . . . over line G. Negative "1"signals on any of lines L1, L2 ... will now cause the corresponding gates T7, T10 ... to set the corresponding storage toggles TOG1, TOG2 ... to "1". When the seize signal SS ends the transistor T6 is cut-off (via its base) so that signals on lines L1, L2 ... have no further effect. After the application of the seize signal SS and until the data stored in toggles TOG1, TOG2 , .. has been utilized via leads 01, 02..., a hold signal HS is applied as shown to prevent regularly-arriving reset pulses RP from resetting the control toggle TOGC and thus returning the circuit to the quiescent state. The set of input leads L1, L2 ... may be common to a number of arrangements of the type shown, the seize signal SS being supplied only to the arrangement required to store the information. The invention may be used in automatic telephone systems and computers.

Title: Dyed resinous pigments
IPC: C09B67/20
Filed: 1956-10-08
Abstract: Finely-divided resinous particles of copolymers containing 70 to 96.5 per cent vinyl chloride, 1.5 to 25 per cent vinyl acetate and 2 to 20 per cent vinyl alcohol and obtained by the partial hydrolysis of vinyl chloride-vinyl acetate copolymers are dyed by immersing in a dye bath comprising a solvent, e.g. water, kerosene and mineral spirits, for the dye in which the resinous particles are insoluble. Hydrolysis may be effected by dissolving the vinyl chloride-vinyl acetate copolymers in solvents, e.g. methyl ethyl ketone and ethyl acetate, and heating with an aliphatic alcohol, e.g. methanol, ethanol and propanol, in the presence of a catalyst, e.g. sulphuric acid and sodium methylate.  The modified copolymers may be recovered by precipitation with methanol.  The dye-bath may contain wetting agents, e.g. iso-octyl phenyl ether of polyethylene glycol, and higher fatty acids, e.g. oleic acid, or metal soaps thereof, e.g. calcium oleate, which may be formed in situ.  Daylight fluorescent dyes, e.g. rhodamine B base or hydrochloride and 4-amino-1,8-naphthol-21,41-dimethyl phenyl imide, may be used and the pigments mixed with varnish vehicles, e.g. an oil-modified alkyd resin derived from phthalic anhydride, polyhydric alcohols and soya fatty acids, mixed with aluminium stearate, a metal naphthenate and kerosene, and used in silk screen and letterpress inks and paints. Alternatively the resinous particles may be dyed in situ in the varnish vehicle.

Abstract: 442,795. Door holders. GIBBONS, F. J. J., St. John's Works, Church Lane, Wolverhampton. Oct. 29, 1934, No. 30978. [Class 65 (i)] In a device for holding doors in an open position comprising a hook and a pivoted arm, one of which is fixed to the door, while the other is stationary, the pivoted arm, which is adapted to engage the hook by its free end, is releasably held in one of two alternative positions by a spring pawl, the positions being such that in one the arm is engaged with the hook while in the other it is tiisengaged therefrom. The hook-shaped member a<1>, which is preferably fixed to the door, is provided with a ramp a<3> which in the opening movement engages a roller c mounted between two arms b<1> pivoted at f to an extension e of a floor bracket d. The arms blare angularly movable and are held either in the substantially horizontal position shown, or vertically, by a spring- pressed ball mounted in the extension e and adapted to engage one or other of two holes b<4>, b<3>, according to the position of the arms b<1>. The recess b<4> is made shallower than the recess b<3> so that the arms can be moved more easily from the horizontal position than from the vertical position, and, as the door is opened, the roller c rides up the ramp a<3> into the hook, while the spring-pressed ball is forced from the recess b<4> and moves into the recess b<3>, the latter movement being produced by the spring, which is relatively strong, and this causes the movement of the arms b<1> towards the vertical to be continued independently of the thrust of the door.

Abstract: 477,861. Coating metals; annealing. ARMSTRONG, J. J. V. Nov. 13, 1936, No. 30983. Convention date, Nov. 16, 1935. [Classes 72 and 82 (ii)] [Also in Groups XXII and XII In an apparatus and method for the heat-treatment of long lengths of metal, successive portions are heated by electric resistance using spaced electrodes and subsequently cooling and quenching operations are performed. The metal may be long lengths of copper coated metal which may be tube formed from strip stock. The tube may be heated above the melting point of copper thereby forming copper welded tubes. A non - oxidizing atmosphere may be used throughout. As shown, a tube A passes between rollers 1 and roller electrodes shaped to the tube bear on it and are arranged in containers through which the tube passes and which are supplied with reducing gas. The tube enters the container 3 through a tube 6 and between the containers passes through a tube 10, container 4 and tubes for cooling and quenching. An oil that cracks and deposits carbon is used for coating the tube. Spring-pressed plungers 23, 26 transmit pressure to corresponding rollers 22, 25 bearing on the tube. The electrode rollers 21 are driven by a belt from the rollers 5. Certain of the electric circuits are controlled by presence or absence of the work. The cooling section involves a water jacketed unit connected to but sealed from the container 4. An outer jacket 31 connected to a water main 35 houses an inner pipe joined to the container 4. A tank 45 supplies reducing gas and a pipe 46 leads to a dryer 47. Oil under pressure from a pipe 75 passes to quenching unit 70 having outer and inner jacket, the latter provided with apertures for oil to be forced through against the tube.
