Title: Weapon firing system
IPC: F41A19/58
Filed: 1982-02-10
Abstract: Prior to weapon interrogation, each weapon is tested via a stray voltage detector (32) to detect the presence of positive or negative voltage levels or pulses that may appear on an igniter and be indicative of an unsafe condition. The stray voltage detector is connected to the igniters (12, 12A, 12B, 12N) which are sequentially powered, and provides an output (ES) to the computer for alerting the operator of the potentially unsafe condition. During weapon interrogation a computer (8) provides a signal (at 27) for closing a normally open switch (16) and signals (at 29, 29A, 29B, 29N) for connecting one of the weapon select relays (18, 18A, 18B, 18N) to the switch. A low level interrogation signal (from 20) is applied through the closed switch and the one relay to a weapon igniter (12, 12A, 12B, 12N) connected to a corresponding weapon (2, 2A, 2B, 2N) to interrogate the availability of the weapon for firing. The igniter provides an impedance indicative of said availability, which is sensed by a sensor (28) for providing a signal (EL) which is applied to the computer for mission programming and display purposes. During weapon firing, a fire signal (from 32) is applied through the closed switch and one of the relays connected to the switch to fire the weapon connected to the relay in a firing sequence depending on the availability of the weapons. <IMAGE>

Title: Compatible high definition television system
Inventor: HURST ROBERT NORMAN
IPC: H04N7/00
Filed: 1983-02-11
Abstract: A high definition camera 400 produces high definition signals which can be sent directly to an appropriate high definition monitor 1012 or alternatively, in the compatible system can be low passed filtered 1010 to produce a low definition signal compatible with a normal standard monitor 710. To reduce bandwidth the low definition signal is subtracted 1014 from the high definition signal to produce difference signals ??? which may be inserted into the blanking intervals of a normal T.V. signal, or transmitted separately as shown. In high definition monitor the difference signals are added to the low definition signals 1018 to reconstitute the high definition signals. Production of the difference signals may be inhibited where there is motion in the image. The high definition signals are produced by selecting pixels alternatively from adjacent line scans either by a sinuous scan or by selecting pixels from a store. The specification discloses systems with and without bandwidth reduction, cameras, monitors, and analogue and digital signal processing techniques. <IMAGE>

Title: Apparatus for well logging while drilling
Inventor: MUMBY EDWARD SHELDON
IPC: E21B47/18
Filed: 1981-10-02
Abstract: A monostable, solenoid-operated valve in a passage which bypasses the drilling fluid pressure drop across a drill bit (34) at the lower end of a drill string (28) in a well opens and closes in response to downhole conditions to create pressure pulses in the drilling fluid. The valve (166) is urged toward a closed position by drilling fluid pumped through the drill string. A larger force is required to open the valve (166) than to hold it open. Current supplied to the solenoid (67, 70) to open the valve is thereafter reduced to a value sufficient to hold the valve open. The solenoid is de-energized to close the valve.

Title: Method and apparatus for applying elastic strips to a continuously moving material web
Inventor: STEMMLER KURT
IPC: A61F13/15
Filed: 1983-10-13
Abstract: By reference to an example relating to the manufacture of disposable panty napkins, a method and apparatus are described for applying rubber strips to the leg portions of the napkins. These rubber strips are intended to provide an optimum fit on the wearer's thighs. Since the consumption of rubber strips in the manufacture of panty napkins is a considerable item in the production costs, and the prior-art methods use more rubber strips than necessary for the purpose in the finished napkin, the object of the invention is to limit the length of the required rubber strips to the functional minimum. This is achieved by a method and apparatus in which predetermined lengths are first severed from the unstretched rubber strip in a continuous movement, the resulting sections are stretched, adhesive is either applied to the sections or to the napkin material, and the sections are then applied to the web of sheeting forming the outside of the napkin.

Title: Granulation of metal sheet
Inventor: HARVEY PETER
IPC: B02C18/14
Filed: 1985-04-11
Abstract: A process for granulating metal received in sheet form, such as cathode copper, operates in two stages. In the first (prime cutting) a sheet from a stack 1 is advanced and pieces are taken from its leading edge by a shear 5 comprising a rotor with at least one blade co-operating with a fixed blade across which the sheet metal is fed. In the second operation, (digestion) the pieces formed in the first operation are fed via a conveyor 7 to a granulator 8 (or to more than one granulator) of the kind comprising a rotor with at least one blade co-operating with at least one fixed blade to comminute the material repeatedly until the particles are small enough to pass through a screen bounding the working zone. The two operations can be optimised independently, and substantial energy saving is achieved compared with the direct feeding of the sheet metal to the granulator. In the case of copper, the extent of heating, which in conventional granulation may lead to surface oxidation, is greatly reduced. A second conveyor 10 may be provided to transport granuals, produced in the granulator 8, to a sieving apparatus 51 and magnetic separation apparatus 11. <IMAGE>
