Title: Improvements in and relating to synchronising arrangements for television systems
IPC: H04N5/067
Filed: 1942-02-12
Abstract: 621,484. Television. FRANCE, H. DE. Feb. 12, 1942, No. 1876. Convention date, March 12, 1941. [Class 40 (iii)] In a television system in which the vision signals are amplitude-modulations of a carrier frequency, the frame synchronizing signals are transmitted by a variation of the carrier frequency and the line synchronizing signals are transmitted by amplitude-modulation of the carrier frequency, irrespective of its frequency variations. In the diagrammatic arrangement, Fig. 1, picture signals from an iconoscope Ic together with frame and line synchronizing signals from generators i, l respectively, are fed to a modulator M and a final stage E<3> of a transmitter. The frame signals i are also fed to a control device S so that during the frame signals an oscillator I generating a frequency n is connected to the transmitter arrangement E<1>, E<2>, E<3> in lieu of the oscillator I<1> generating a frequency n<1>. During the interval between the frame signals 1, Fig. 2, the valve 2 is non- conducting and the valves 3, 4 are passing current, the operation of the valve 4 preventing the valve 5 from operating so that the voltage at the point D is relatively positive and operates the valve 71 of a valve pair 6<1>, 7<1> forming the oscillator I<1> and generating a frequency n<1>. The frame synchronizing pulses 1 bias the valve 2 into operation and the valves 3, 4 are cut off. When the valve 4 becomes non-conducting, the valve 5 passes current so that the potential at the point C becomes relatively positive and effects the operation of the valve 7 of the pair 6, 7 forming the oscillator I generating the frequency n. The line-synchronizing pulses are applied to the frequencies n, n<1>. The frequencies generated by the oscillators I, I<1> are preferably amplified and multiplied at 8 so that the carrier frequencies transmitted are multiples of the frequencies n, n<1>. The carrier frequencies employed may differ by about 500,000 cycles per second. The frequencyvariation utilized for the frame synchronizing signals may be a frequency-modulation of the normal carrier.

Title: Sewing machine
IPC: D05B15/02
Filed: 1924-01-23
Abstract: 218,936. Fairweather, W. C., (Singer Manufacturing Co.). Jan. 23, 1924. Sewing-machines; trimming or cutting. - A lever 42 to which is adjustably fixed an edgesnipping cutter 45, is pivoted at 39 and has pivoted thereto an arm 51 which engages with an eccentric 52 on a shaft 54 under the influence of a spring 46. The shaft 54 actuates the cutter once during each two stitches. A manually-actuated rock shaft 63 carries a gapped cam-plate 62. To disengage the cutter from its actuating- mechanism, the handle 65, Fig. 2, is turned to the right when the surface 69 of the plate 62 engages a pin 67 on the arm 51 and disengages the latter from the cam 52, the spring 46 now holding the cutter in inoperative position. To start the cutter. the handle 65 is turned to the left when the plate 62 engages the hub 48 on the lever 42 and raises it to allow the arm 51 to swing into operative position assisted by the interaction of the surface 71 of the plate and the pin 67. Stops 47, 68 on the frame and the plate 62 respectively limit the movements of the lever 42 and the arm 51 to inoperative position. This construction is particularly useful for snipping the edges of the work when sewing round sharp curves while French-cording boot-uppers and the like, as shown in Fig. 8. The cutter 45 is also adjustable laterally of its cutting edge by means of a set-screw 76. Work-supports.-The cutter 45 coacts with a ledger-block 72 on the throat-plate 29, Fig. 4, and is held yielding thereagainst by a spring- pressed follower 74, the edge of which is slightly bevelled to facilitate the entry of the cutter.

Abstract: 601,373. Feeding sheets. MILLER PRINTING MACHINERY CO. Feb. 19, 1941, No. 2282. Convention date, Feb. 20, 1940. [Class 100(i)] A feeding apparatus for sheets &c. is described in connection with means for feeding sheets to a cylinder printing- machine, the apparatus comprises a reciprocating transfer device for carrying a sheet to a given position from which it is taken by a second transfer device and fed to the machine. The sheets are separated from an automatically raised pile 4 by a reciprocating suction separator comprising four suction nozzles 109, Fig. 12, suspended from a vertically reciprocating bar 105 and having flexible connections with a valve 113 which controls the air pressure in the nozzles. The separated sheets are taken from the nozzles 109 by nozzles 61 on a reciprocating carrier A, and finally the sheets are taken by nozzles 63 on a carrier B which reciprocates synchronously with the carrier A but at a slower speed and in opposite directions. The carriers are operated by racks 55, 54 in gear with gears 53, 52 of different sizes on a common operating shaft 51 which is geared to a shaft 11 which is oscillated by a reciprocating rack 13 operated by cam- and-lever mechanism from a main driving shaft which is driven through a clutch controllable by rotating a cam through a half-revolution. The carrier A moves quicker and travels further than the carrier B, and the carrier B moves more slowly when towards the front stops 3 than when moving in the other direction. The nozzles 61, 63 are shown in full lines in Fig. 2 in the positions in which the sheets are received from the pile and delivered to the front stops respectively, and in dotted lines in the sheet transfer position. The nozzles 61, 63 are offset laterally, and their supports are constructed to permit the nozzles to be brought into line forsheet transfer. The rod 105 is carried by links 103, 103a, which are reciprocated by bellcrank levers 94 and cams 89 on a cam shaft 88. This shaft also carries cams for operating valves 113, 113a, 113b for controlling the air pressures in the suction nozzles. The valve which controls the air pressure in the nozzles 63 is formed with bleed ports which are arranged to cause the sheets to be held less firmly while being presented to the front stops, so that the nozzles can move on relatively to the sheets when these are held by the stops. The sheets are side-registered by pushers operated by an oscillating bell-crank lever which can be set to register the sheet from the right or from the left.
