Title: An igniter for an explosive device
IPC: F42C14/08
Filed: 1979-12-18
Abstract: An igniter for an explosive mine includes a main body 1 having an upper cup-shaped portion presenting an annular edge 2 on which bears an actuating cap 3 able to pivot about the tangent at any point on the circumference of edge 2. Main body 1 has a bottom annular flange 19 connected to the rest of the body by a thin bridge, whereby the igniter can be connected to the mine by a suitable bush 20. A striker 5 biased by a spring 8 is held in an inoperative position in body 1 by a retaining sleeve 7 carrying balls 6 engaging in a groove 5' on the striker. Sleeve 7 is connected to the cap by a link 11 for withdrawing sleeve 7 upwardly and releasing striker 5 on pivoting of the cap 3. A detonator 10 is mounted in the path of the striker 5 by a bush 17 screwed to the main body 1. A retractable safety pin is provided to hold the cap 3, and body 1 relatively immovable until the mine is used. The described igniter construction enables the igniter to be stored separately from the mine and also permits the detonator to be stored separately from the rest of the igniter. <IMAGE>

Title: Service Call Arrangements e.g. for Restaurants
IPC: H04B10/114
Filed: 1980-09-05
Abstract: A service call arrangement, for e.g. a restaurant, comprises call transmitters (2', 5', etc) positioned at the various tables (2, 5 etc) where service is required, each transmitter being operable to transmit a distinct individual call signal to a central receiver station (11) where a group of illuminable press-buttons (1 to 6) is provided.

Patent GB-2078243-A (GB)
Title: Multicolour Coating Composition
IPC: C09D5/29
Filed: 1981-06-18
Abstract: The composition is of the type in which a number of discrete colored globules of a size visible to the naked eye are dispered in an aqueous medium of a color different from that of the globules. The globules comprise a mixed organic complex reaction product resulting from both ionic and non-colloid reactions of two polyelectrolytes of opposite charges and a reactant which forms a complex with one of the polyelectrolytes and are of sufficient strength and fluidity as to not subdivide substantially when brushed or rolled on a desired substrate. The aqueous medium by the use of thickness or rheology modifiers, preferably of the associative type, is adjusted to have a viscosity profile that approaches Newtonian, with good resistance to brushing at high shear rates, and the composition leveling after application is complete. The polyelectrolytes may be ionic derivatives of synthetic resins or polysaccharides, and the complexing reactant may be a soluble boron compound or an organotitanium compound.

Title: CO2 Laser with Catalyst
IPC: H01S3/038
Filed: 1981-08-17
Abstract: A CO2(-N2-He) laser has the lasing medium in contact with a catalyst mounted upon a metallic substrate, the catalyst catalysing the reaction  2CO+O2=2CO2 to alleviate degradation of laser performance due to breakdown of CO2 by the electric discharge in a sealed system The metallic substrate is preferably an aluminium-containing ferritic steel having a surface coating of alumina in which the catalyst (for example platinum or palladium) is impregnated. A current may be driven through the catalyst to heat it to 200 DEG C. The metallic substrate provides a rugged catalyst system which is not brittle and not sensitive to fracture when subjected to the temperature changes involved inside a laser which may be frequently switched on and off. By impregnating the catalyst in a porous alumina surface on ferritic steel, a large catalytic surface area is available.

Title: Bending tool for bending of wire, band and like stock into zigzag-shape
IPC: B21F1/04
Filed: 1981-10-16
Abstract: A bending tool for the bending of wire, band and like stock (5) into zigzag- shape includes two bending heads (1, 2) which operate together during a single bending operation. The bending heads (1, 2) are arranged, in the neutral position between the bending operations, to lie substantially aligned with the feed direction of the stock situated opposite each other in such a way that the stock to be bent (5) can be advanced straight through the tool adjacent the heads. During the zigzag-bending operation the bending heads (1, 2) are adapted to carry out opposite, uniform turning movements from the neutral position while the distance between them is maintained unchanged, so that the input and output directions of the stock relative to the tool remain substantially the same. In the Figure, the heads and stock 5 are shown in both the position before zigzag formation (1', 2') and after (1'',2''). <IMAGE>

Patent GB-2146119-A (GB)
Title: Detection of fuel injection
Inventor: FROUDE CONSINE LIMITED
IPC: F02P17/00
Filed: 1983-09-05
Abstract: In order to detect fuel injection in a compression-ignition engine, an electro-acoustic transducer 1, such as a piezo-electric transducer, is used to monitor a fuel injector or fuel pump of the engine. The output signals from the transducer are supplied to an automatic gain control circuit 6 which controls the gain applied to the signals so that the dynamic range thereof is adjusted to a suitable value. The envelope of the output signals from the circuit 6 are de-modulated in an envelope detector 10 and supplied to a comparator 11 which produces an output signal when the envelope rises above a reference value provided by a reference voltage generator 13. The leading edge of the signal from the comparator indicates the onset of fuel injection in the engine. The AGC circuit 6 adapts the apparatus automatically to the testing environment and allows the apparatus to be used with engines of all types without requiring any pre-adjustment. <IMAGE>
