Title: Wire wrapping apparatus and method
IPC: B65H81/08
Filed: 1973-04-10
Abstract: 1438536 Winding wire USS ENGS & CONSULTANTS Inc 10 April 1973 [27 April 1972] 17173/73 Heading B3F Apparatus for wrapping a wire under tension round a conduit comprises a wire supply subject to a friction drag to prevent uncontrolled payout, the supply feeding a wire tensioning device on which a plurality of turns of wire are stored, and which is rotated and moved longitudinally relative to the conduit to wrap the wire around it. In the Figure, the wire supply 28 comprises a reel 30 supported on the conduit 16 by castors 29, and the tensioning device 46a comprises a drum 48 rotatably mounted on a head 20 surrounding the conduit and supported thereon by wheels 22. The reel and head are connected together at 34 by a joint permitting relative rotation subject to friction, and limiting relative longitudinal movement. A head drive device 58 is supported on the wrapped part of the conduit by wheels 70 driven from one output shaft 64 of motor 62. The head 20 is connected to an extension 61 of drive device 58 by a joint permitting relative rotation but not longitudinal movement, and the head is rotated by ring gear 78 and spur gear 76 on the other output shaft 72 of motor 62. In operation, wire 10 from the reel is wrapped around drum 48 and anchored to the conduit at 14. As the drive device 58 rotates and advances the head, drum 48 applies torque to wheels 22 through a drive 92 in the sense to drive the head in the direction in which it is driven by drive device 58. The torque may be limited by a clutch or brake device. The wire may be fed off reel 28 in either sense, so that the reel rotates faster or slower than the head. Three wires may be wound on to the conduit side-by-side, two of the reels being located within head 20, which is then made in hinged halves to provide access, see Figs. 3 and 8 (not shown). In an alternative embodiment the reel (or reels) is mounted on a post or head 20, frictional restraint being applied between the post and reel.

Abstract: 1,270,638. Making alloys. EUROPEAN ATOMIC ENERGY COMMUNITY. April 14, 1970 [April 29, 1969], No. 17748/70. Heading C7D. A process for the production of alloys occurs at a pressure not greater than 10<SP>-4</SP> Torr and consists of condensing an ionic vapour containing at least one alloy constituent on a solid substrate containing the other constituent(s) so as to form a molten alloy which by gravity runs off the substrate, the temperature of the substrate being equal to the liquidus melting temperature of the alloy. The substrate preferably has a potential with respect to the source of the vapour, of between 10 and 150 volts. Either the substrate may consist of more than one element and/or the vapour may be derived from more than one source. In a suitable apparatus see Fig.2 sources 2 and 21 are evaporated by means of electron guns outside the chamber via apertures 8, 8<SP>1</SP>, the vapour condensing on rotating substrate 1 and dripping from there into mould 3. The substrates 2, 2' may also be rotated. The walls 6, 6<SP>1</SP> are preferably at a temperature such that the vapour will not condense thereon. The walls 6, 6<SP>1</SP> may be of the same material as the respective sources. The whole chamber and electron guns (not shown) are contained in a vacuum chamber. Fig. 1 (not shown) shows a suitable apparatus having a single source. It is stated that more than two sources may be used in similar fashion. The composition of the final alloy may be adjusted by (a) varying the temperature of the substrate (b) varying the energy of the electron guns and (c) varying the area of each sub-chamber to which the substrate is exposed.

Title: Improvements relating to television systems
Inventor: HUNT GEORGE ARTHUR
IPC: H04N5/06
Filed: 1959-05-28
Abstract: 887,532. Television. BRITISH BROADCASTING CORPORATION. May 30, 1960 [May 28, 1959], No. 18277/59. Class 40(3). A television line synchronizing signal, Fig. 1, starts with a blacker-than-black pulse a, rises steeply to a peak-white reference level b, thereby providing a reference timing edge S for synchronization which occupies the full amplitude range of the video signal, and terminates with back porch c which provides a black reference level. A frame synchronizing pulse consists of a plurality, for example three, of line synchronizing signals. The signals are generated at a transmitter, Fig. 3, by means of three pulse generators A, B and C which are set in operation by line trigger pulses and trigger each other in sequence to generate respectively the pulses a, b and c. The three pulses are then added with appropriate amplitude and sign in a matrix M1 to furnish the line synchronizing signal. The frame synchronizing signal is produced in response to a frame trigger pulse which triggers a pulse generator D. The generator controls a gate L connected between the output of generator C and the input of generator A. The pulse from D lasts for approximately the duration of half a line, whereby following the production of a line signal, generators A, B and C cycle for three further signals to produce a frame signal. A second matrix M2 adds pulses a, b and c to produce line blanking pulses and also receives pulses of approximately 2¢ line periods from a generator E to produce frame blanking pulses. The synchronizing signals appearing at the output of matrix M1 are inserted into a video signal in a conventional manner with the aid of the blanking pulses appearing at the output of matrix M2. At a receiver, Fig. 4, a network "p" having an optimum signalto-noise ratio for pulse a, applies the received signal to a separator which separates pulse a. This pulse is then applied to open a gate 1 and as a result of the inherent delay in network "p" controls the gate to be transmissive for an interval including the synchronizing edge S. The received signal is applied to gate 1 through a network "q" having an optimum signal-to-noise ratio for edge S. The output of gate 1 comprising the combined line and frame pulses is applied to a normally open gate 3, a normally closed gate 2 and a network N having a delay approximately equal to the added duration of pulses a, b and c. The output of the network controls gates 3 and 2 so as to close and open them respectively. Each line pulse thus passes through gate 3, whereas the group of three pulses forming the frame signals passes through gate 2, which is opened at each pulse by the delayed preceding pulse obtained via network N.
