Title: Laminated sheet material
IPC: B32B27/00
Filed: 1963-03-02
Abstract: 988,816. Laminates; films. O. B. RASMUSSEN. Feb. 28, 1964 [March 2, 1963], No. 8429/63. Headings B5B and B5N. A laminated sheet has at least two plies of uni-axially oriented film of organic thermoplastic material bonded together so that the directions of orientation of adjacent plies cross, at least one of the plies containing a multitude of interior microcavities which do not penetrate through the ply from one surface to the other. Preferably, the thermoplastic material is an 1-olefins such as high density polyethylene and ethylene co-polymers or highly crystalline polypropylene. Preferably the cavities are produced by forming a film containing a major amount of the orientable 1-olefine and a minor amount of a foreign polymer capable of swelling when exposed to a volatile solvent which does not significantly swell the 1-olefins polymer, applying such a solvent and thereafter evaporating it by heating. Suitable foreign polymers indude esters of polyacrylic acid, polyvinyl esters, polyvinyl ethers, polystyrene, polyvinyl chloride, cellulosic polymers, polycarbonates, polyvinyl butyral &c. Several examples of suitable volatile solvents are given. The volatile or gas forming agent may be incorporated before or after orientation of the film, but is not removed until after orientation. Preferably, three plies are used, each containing a multitude of interior microcavities, and they are associated so that the directions of orientation of adjacent plies form 45-60 degrees with each other, the orientation of the centre ply being preferably parallel to the longitudinal direction of the sheet. The plies may be bonded together by welding with solvents or heat, or preferably with a pressure-sensitive adhesive, e.g. polyisobutylene, polyvinyl-isobutyl ether, a normally tacky fatty-polyamide used alone or with 20-30% of micro crystalline wax. The oriented films may be produced by bias-cutting stretched tubular extruded film. Specifications 816,607 and 865,707 are referred to.

Title: Improvements relating to semi-permanent magnetic memory elements and memory matrixes using such elements
IPC: G11C17/02
Filed: 1966-02-25
Abstract: 1,138,588. Semi-permanent data stores. KOKUSAI DENSHIN DENWA K.K. 25 Feb., 1966 [27 Feb., 1965; 8 March, 1965; 26 May, 1965], No. 8534/66. Heading G4A. A magnet semi-permanent memory element comprises a ferromagnetic thin film, two orthogonally arranged conductors associated therewith and means to establish the rest magnetization of the thin film in either of two different directions in accordance with binary information to be stored, the arrangement being such that on passing a drive current through a first of said conductors an output signal having either of two opposite polarities in accordance with the stored binary information is produced in second of said conductors. The two signals are of equal amplitude. The elements may be arranged into a matrix as shown in Fig. 10 wherein the thin film is formed as a coating around said second conductors 3 with a circumferential easy direction of magnetization. The rest direction of magnetization Mr of each memory element located at an intersection of a column conductor 2 (comprising said first conductor) with a row conductor 3 is established either by a bias field (Hw-Fig. 3a) maintained in conductors 3 by sources 10 or by said bias field Hw together with a field HO (Fig. 3b) provided by a permanent magnet 4. On passing a drive current through a selected conductor 2 whereby a field Hd is produced in the thin films associated therewith just sufficient to cancel out the fields HO (where these exist), the resultant magnetization Mr swings through an angle # as shown in Figs. 3a and 4a or 3b and 4b. The resulting output pulses are passed by a transformer 9 to an amplifier as shown. In a modified arrangement (Fig. 11, not shown), the thin film is coated on the drive conductors, the easy direction of magnetization is axial, the bias field is dispensed with and binary information is stored by permanent magnets placed axially along the drive conductors in either of two opposite directions. Means 4 other than bar magnets for establishing the rest direction of magnetization comprise a ferro-magnetic layer only selected portions of which are magnetized or a ferro-magnetic film with holes therein, the magnetic field, between this film and the conductors being established in closed loops by bridge pieces as illustrated in Fig. 12 (not shown). Intersections at which it is not required to store information may be left without the permanent magnets or other means 4 without upsetting operation of the matrix.

Class 142(1) Droppers 6 in a magazine 7 are moved downwards for threading one at a time by a pin 1 on a selector arm 2 driven by a crankshaft 3. The pin engages a slot in the dropper and moves down until the crankshaft is at bottom dead centre when feed rollers 8, 9 grip the dropper. At bottom dead centre a Geneva mechanism 20 causes a cylinder 19 to turn so that a peg 15 is not opposite a follower 27 on a lever 12 pivoted at 13. The lever 12 turns slightly clockwise and a retainer 11 engages the next dropper 10 to prevent it being moved downwards with dropper 6. A member 33 on the lever 12 pivots the arm 2 clockwise to withdraw the pin 1 from the dropper 6 and the crankshaft 3 returns the arm 2 and pin 1 to the initial position. A number of magazines may be arranged side-by-side to thread several rows of droppers simultaneously, the shaft 3 and cylinder 19 being common to all magazines. The cylinder 19 can be moved axially on shaft 21 and locked in position thereby bringing the pegs 15 opposite selected magazines. By selection of the pegs 15 and axial movement of the cylinder the droppers can be selected in a given combination of rows. A dropper engages a feeler 22 to operate a microswitch and indicate to the operative and stop the machine if a dropper is not selected at the appropriate time for its magazine.

Title: Synchronous detectors
IPC: H04N9/66
Filed: 1955-03-28
Abstract: 774,441. Colour television. RADIO CORPORATION OF AMERICA. March 28, 1955 [April 26, 1954], No. 9048/55. Class 40 (3). [Also in Group XL (c)] A synchronous detector for demodulating the colour sub-carrier wave in a colour television system comprises a valve arranged for class C operation with the sub-carrier wave applied to its anode and a demodulating wave of same frequency and appropriate phase applied to its grid. Fig. 6 shows an arrangement of three synchronous detectors 75, 79, 83 intended to produce the three colour-difference signals R-Y, G-Y and B-Y from a sub-carrier modulated in quadrature by " I " and " Q " signals respectively along the orange-cyan and green-purple axis. The sub-carrier is associated with a luminance signal Y. The sub-carrier, together with the luminance signal, is derived through a video amplifier 139 and applied in common to the anode circuits of the three detectors, whilst locally-generated waves of the same frequency but different phases appropriately chosen to demodulate the colourdifference signals are applied to the three grids. The grid circuits include CR couplings which together with waves of sufficient amplitude cause self-biasing for class C operation. The colour-difference signals R-Y, G-Y and B-Y appear across valves 75, 79 and 83, respectively but are each combined with the luminance signal Y, which also appears through amplifier 139, and hence individual colour signals R, G and B appear on leads 157, 159 and 151. These signals may then be applied directly to appropriate grids in a colour cathode-ray tube. Due to the D.C. couplings which exist throughout the circuit no D.C. restorers are necessary. The anode coupling circuit 144 of the video amplifier is peaked over the range occupied by the subcarrier. Each detector is followed by a filter which has a response arranged to suppress the sub-carrier frequency. In another arrangement, Fig. 8, in which only the red detector is illustrated, the sub-carrier is applied to the anode of the detector valve 220 by coupling from a tuned circuit 205 in the video amplifier 173. The luminance signal is here eliminated from the detector circuit which thus produces a colour-difference signal. This signal is applied to the grid of the cathode-ray tube over lead 213. The luminance signal is derived through a separate channel permitting its amplitude to be independently controlled and is applied to the cathode of the cathode-ray tube. Circuit 211 is a trap tuned to the sub-carrier frequency. Reference is made to the use of two synchronous detectors to derive the " I " and " Q " signals, the colour signals being obtained from these by a suitable matrix and adder circuit.
