Patent GB-2021317-A (GB)
Title: Electrical roll capacitor with safety cut-out device
IPC: H01G4/32
Filed: 1979-04-20
Abstract: An electric roll capacitor consists of a tape roll (1) wound on a tubular core (2) the tape shrinking radially under the effect of heat and compressing the core at its centre so as to elongate its ends. These deformations are used to break the circuit of the capacitor in a precise manner by connecting the ends (13, 14) of the core (2) by an essentially inextensible connection (10, 11; 12) which, however, includes a weakened area (7; 8) breaking on elongation of the core. The weakened area is located at the internal centre of the core and may be constituted by a short, frangible wire (7) connected between two rigid rods (10, 11) having a central notch (8), optionally assisted by a further area (15) which acts as a fuse by melting or softening under the effect of heat. <IMAGE>

Title: Chemical resistant and non- inflammable textile
IPC: D01F9/32
Filed: 1979-05-08
Abstract: Chemical resistant, non-inflammable textile is produced by passing an ammoniated web comprising a blend of acrylonitrile and cellulose through a chamber (11) [Fig. 2] where the web is subject to oxidation at 90-200 DEG C then through two tunnels operating at reduced pressure each having a liquid seal at the inlet and outlet. In the first tunnel (16) [Fig. 4] the web is sprayed with a dispersion of copper salt in a fluorocarbon carrier. In the second tunnel (17) [Fig. 5] the web is subject to carbonization in an inert atmosphere whilst being heated to 275-325 DEG C.

Title: Process for Preparing Non- Crystallizing Starch Syrups Containing Both Dextrose and Maltose
IPC: C13K7/00
Filed: 1979-05-23
Abstract: Syrups containing substantial amounts of dextrose and maltose (e.g., syrups containing 35%-40% dextrose, about 35% maltose, the balance being higher saccharides), are continuously prepared by passing a starch hydrolyzate containing maltose in an amount greater than that desired in the final product through a column of immobilized glucoamylase to bring the dextrose content to the desired level. Problems invariably encountered in stopping completely the saccharification reaction at precisely the desired end-point are thus overcome.

Title: Improvements in or relating to visual display apparatus
IPC: G02B27/00
Filed: 1979-12-19
Abstract: The invention provides head-coupled area-of-interest visual display apparatus particularly for ground-based craft-flight simulators. The apparatus provides a stereoscopic pair of images the two images being separately projected from points on the pilot's helmet above the pilot's eye positions, onto the inside of a part-spherical shell which surrounds the pilot and carries a retro-reflective screen. The displayed scene covers an area of interest centred upon the pilot's line of view. The image generator used may be of the computer generated image, laser-scanned model or closed-circuit television type. Line scan apparatus is mounted in the pilot cockpit; line image transmission is by a pair of fibre optic light guide ribbons; and frame scan apparatus is mounted on the pilot's helmet. Sensing means detect head/helmet movements to permit voluntary scanning of a wide angle of simulated pilot view from the craft. <IMAGE>

Title: Actuator for a lever for locking an automobile lock
IPC: E05B65/36
Filed: 1980-06-04
Abstract: The actuator has a carriage (8) which is connected to the lever to be shifted.

Title: Wet cell battery level sensor
IPC: G01F23/22
Filed: 1980-12-22
Abstract: A tester for the electrolyte in a wet cell battery has an electrically conductive level sensor 21 which loses contact with the electrolyte when the level gets too low. A circuit arrangement connected to the cell and to the sensor 21 uses a potential derived from the battery to activate an indicator LED when the level falls below the sensor 21. The sensor may be used to affect the base potential of a transistor which acts as a switch for a light emitting diode. This gives an automatic warning when the cell needs topping-up. <IMAGE>

Patent GB-2077559-A (GB)
Title: Variable characteristic filters
IPC: H03H11/12
Filed: 1981-05-22
Abstract: A variable characteristic filter is described in which output signals are frequency analysed by means of a frequency-to-voltage converter (26) to derive a control signal dependent on the frequency content of the analysed signals other than noise of random frequency. Variable impedance elements (23) in the filter are controlled by the control signal to vary the filter characteristic automatically to exclude the noise. The filter, including the frequency-to-voltage converter, may be such that the filter attenuation is reduced in the frequency region where the input or output signals mainly occur. The invention is particularly useful in Doppler blood-flow velocimeters to reduce noise. <IMAGE>

Filed: 1981-09-07
Abstract: A central control comprises two identical processors A, B, each of which includes a central memory unit 1, a central processing unit 2, and an input- output unit 3 which is connected to peripheral users 5. Each central processing unit 2 comprises a plurality of functional units mutually connected to each other and including a central control unit 6, a watching unit 8, an updating and synchronization unit 9 and a console unit 10.

Two spring loaded plungers 37, 38 are fixed to the stem and spaced apart to co-operate with the cams 61, 62 such that rotation of the stem with respect to the base causes movement of the plungers 37, 38 over the cams from one side to the other i.e. between the first and second positions. A stop means 54, 70 may be provided to restrict the degree of rotational movement. <IMAGE>

Title: Maze board game
Inventor: CAMPBELL MALCOLM
IPC: A63F3/00
Filed: 1982-01-12
Abstract: The game comprises a playing board having a plurality of playing positions (e.g. A1, A2) serially arranged to form paths and spacer regions (A9, A10, A11), which, in combination with at least some of the paths, define one maze (A, B, C, D) for each player. Some of the positions of each maze are marked by a number, and at least one playing card is provided for each player which carries information on which of the marked positions in an opponent player's maze are to be regarded as "open", i.e. positions across which a player's piece may freely move. A random number selector determines the number of steps to be advanced by a player's piece during each move, the object of the game being to proceed move by move from a start position (A1) via a maze (A, B, C, D) and "open" positions known only by an opponent player, to arrive first at a finish position (e.g. A1). <IMAGE>

Title: Series connected solar cells on a single substrate
IPC: H01L31/0465
Filed: 1982-03-24
Abstract: Solar cells (12) in an array (10) are interconnected (26) by heating metal stripes (22), e.g. Cu, Al or Au, to cause them to spike through (26) the semiconductor layer (20), between the upper electrode (24) of one cell and the lower electrode (16) of the next adjacent cell. The stripes may be fabricated using a thick striped pattern material as a lift off mask, so that conductive material applied to the mask during deposition of the stripes, is removed with the mask ("paint and peel" method). Electrodes (24) may be isolated by laser scribing or by deposition using a "paint and peel" method, however it is not necessary for semiconductor layer (20) to be discontinuous between cells because of the low lateral conductivity of this layer. Semiconductor layer (20) may comprise a PIN structure, or I and N type regions and a Schottky barrier. <IMAGE>
