[Also in Divisions B2, C3 and C4] A laminate is obtained by coating a sheet with a mixture of a tetracarboxylic acid dianhydride, a diprimary diamine and water, removing water and applying pressure to a plurality of sheets at 100-400 C., preferably 120-350 C., thereby causing the coating mixture to react and form a polyimide. The mixture preferably contains sufficient ammonia to ensure complete solubility of the dianhydride, and is then applied a solution or dispersion, depending on the solubility of the diamine. Drying may take place below 150 C. The sheet may be satin-type glass fibre fabric. The dianhydrides may have formula where R is aliphatic, cycloaliphatic, herocyclic or aromatic and contains at least 2 carbon atoms.

Title: Arrangement for Contactless Measurement of Displacements
IPC: G01D5/22
Filed: 1967-11-13
Abstract: 1,191,930. Displacement transducers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Nov. 13, 1967 [Nov. 16, 1966], No.51510/67. Heading G1N. In a two dimensional inductive displacement transducer comprising two coils would on ferromagnetic cores whose pole piece are arranged adjacent to a ferromagnetic member, attached to the object whose displacement is to be sensed, the pole pieces are so shaped and disposed that the air gaps between the pole pieces and ferromagnetic member are changed in height in opposite senses by movement of the ferromagnetic member in one of the two measuring directions. By computing functions of the sum and difference, or the sum and difference of functions of the two inductances, signals indicative of the displacement in the two directions are obtained. In one embodiment, Figs. 1a-1c (latter not shown) two U-shaped cores K1, K2 are provided with pole pieces inclining in opposite directions above the ferromagnetic plate 2, attached to e.g. a rotating shaft, for sensing movement of the shaft in the X and Y directions. The inductances of the two coils L1, L2 are shown to vary as (1/y  # x) where # is a constant and x and y the displacements. By forming the sum and difference of the inductive admittance of the two coils, Figs. 2, 3 (not shown), two signals representative of the x and y displacements are provided. In a modification the inductances may each form a component of an oscillator Fig. 4 (not shown), whose frequency is therefore a funtion of its admittance. The sum and difference of these frequencies thus will provide the required signals. In a second embodiment, Figs. 5a-5c (latter not shown), the pole pieces are provided with inclinations relative to each other and orientated in opposite directions. In this case the inductances of the coils vary as (b  Bx / y) where b and B are the the ratio of the difference and sum of the inductances and inductive admittance of the sum of the inductance of the two coils being proportional to x and y respectively. This computation is carried out as shown in Fig. 6, the meters MI and MU indicating the x and y co-ordinates.

Title: Pulsed dynamic co gas laser generator or amplifier
IPC: H01S3/0953
Filed: 1973-11-06
Abstract: 1444266 Lasers MESSERSCHMITT-BOLKOW-BLOHM GmbH 6 Nov 1973 [29 Nov 1972] 51548/73 Heading H1C In a gas dynamic laser, CO gas produced and excited by heating in a chamber 10 is propagated as a wave along an expansion chamber 12 by the rupturing of a diaphragm 11 or the rapid opening of a valve. The expansion chamber includes a resonator 14 and is initially evacuated to a low pressure by a device 13. Finally the expanded and de-excited gas is received by a ballast tank 15 or is condensed by a diffuser and expelled to atmosphere. The heating and expansion chambers 10, 12 may have diverging walls in the direction of gas flow. The CO gas is produced at a temperature from 1000‹ to 4000‹ K., and at a pressure between 10 and 1000 atmospheres, by combustion involving a cyano compound, e.g. C 2 N 2  or C 6 N 4 , and a nitrogen oxide, e.g. NO, NO 2 , N 2 O or air. It is suggested that the expansion chamber may be such that a series of waves are developed from the single wave from the heating chamber so as to prolong the radiative emission time. Alternatively a propagated wave may be reflected.

Abstract: 1,270,915. Coated sheet materials. GIULINI G.m.b.H. GEB. 30 Oct., 1970 [30 Oct., 1969], No. 51791/70. Heading B2E. [Also in Division A3] A stiffening material for use in footwear comprises a textile substrate having on one side a wear surface, provided by coating and/or impregnating the substrate with a carboxylated butadiene-styrene copolymer and on the other side a reinforcing layer provided by coating with a thermoplastic polymeric material, the reinforcing layer being provided with a stickable surface. The stickable surface may be provided by coating with a hot melt or hot sealing adhesive or with an organic polymer partially soluble in a organic solvent or alternatively when certain organic polymers are used to provide the reinforcing layer the reinforcing layer may inherently have a stickable surface. The textile substrate may be a fabric, felt or non-woven fabric, tangled materials bonded by high frequency heat, application of pressure. Specific examples are woven cotton fabrics, of a twill or linen weave. The substrate may have napped surfaces. The carboxylated butadiene-styrene copolymer is preferably a terpolymer containing copolymerised butadiene, styrene and unsaturated carboxylic acid. The substrate may be impregnated and/or coated with an aqueous dispersion of the copolymer and the aqueous dispersion may also contain further organic polymeric materials e.g. acrylic acid copolymers, fillers e.g. titanium dioxide or kaolin and pigments, antifoam agents. The impregnated or coated substrate may be subjected to at least one surface texturing step. The side of the substrate to which the reinforcing layer is to be applied may be provided with a napped surface by passing over the surface of a rotating smoothing roller. The side to provide the wear layer is preferably provided with a smooth surface by passing over the surface of a rotating smoothing roller, the surface of which is travelling in the opposite direction to that of the impregnated substrate. The reinforcing layer is preferably applied as an aqueous dispersion. Preferred dispersions contain a styrene homo- or copolymer and an acrylic acid copolymer, or contains a styrene-butadiene-acrylonitrile terpolymer. Preferred hot melt adhesives contain ethylene-vinylacetate copolymers. Suitable solvent-soluble polymers include polystyrenes. The stiffening material may be shaped to form stiffening inserts e.g. puffs and counters for shoes.

Title: Artillery breech-block
IPC: F41A19/57
Filed: 1974-12-02
Abstract: 1463530 Breech-block assembly RHEINMETALL GmbH 2 Dec 1974 [14 Dec 1973] 52072/74 Heading F3C A gun has a breech plate 10, Figs. 1, 2 and 3, and a breech-block 12 movable relatively to the breech plate 10. A control bar 33 has an L- shaped slot 32 which engages a crank-pin 30 connected to a toothed segment 16. A slide 22 has a rack 24 engaging the segment 16, and has therein a magazine 34, the latter containing primer cups 36 and a spring 38 which urges the cups 36, a stop 40, a striker-pin 44, an ejector pin 46 and a cocking-cam 50. The slide is provided with an ejector aperture 41. When the breech-block 12 moves from its position shown in Fig. 1 to the position shown in Fig. 2, the slide 22 moves in the opposite direction, the ejector-pin 46 aligns with an ejector 18 and a spring 48 effects the expelling of the used primer cup from the breech 14 and through the aperture 41. Continued movement of the breech-block 12 and the slide 22 to the position shown in Fig. 3 causes the cocking-cam 50 to be moved pivotally by a roller 20, carried by the breech-block 12, so as to cock the striker-pin 44 against the urging of a spring 52, Fig. 1, the striker-pin 44 being held in position by a bolt 54 engaging a lug on the pin 44 prior to firing being effected. The next primer cup 36<SP>1</SP> is in alignment with the breech 14 and is transferred from the magazine 34 by a lever 56 which is pivotally mounted at 57 on the slide 22 and is rotated by a cam 60 and a control groove 58. A hand-lever 62, Figs. 4 and 5, is mounted on a shaft 64 having a pinion 65 in engagement with a rack 66 of the control bar 33 so that rotation of the shaft 64, by the hand-lever 62, displaces the bar 33 and, consequently, the control-pin 30 and thus moves the slide 22 from the firing to the loading position. Prior to the hand-lever 62 being operated it is necessary to release a pin 67 and to disengage the cam 60 from the groove 58.

The locking member shown is of non-resilient material but a number of forms are described which are made of resilient material and which are deformed when the resilient member 11 is deformed by the cam member of the pull tab.
