Abstract: 1323268 Electron couplings T JERMYN [trading as JERMYN INDUSTRIES] 29 Nov 1971 [23 April 1971] 11079/71 Heading H2E A socket for mounting components, e.g. integrated circuits, consists of a body of insulating material with channel sections 3, 4, 5, 6 metal plated and contacting plated pins 7 moulded integrally with the body. Ribs 8, 9 and 11 are provided to electrically separate the channels. Plating may be carried out by etching the body, applying overall a layer of nickel and a surface layer of copper, gold or silver, and then machining the surface to remove plating from the ribs. In use, the component is mounted on the top 1 with its leads in the channels. A clamping member (12), Fig. 5 (not shown), is pushed on around the body portion, ramps (13) progressively engaging the channels 3 to wedge the leads between respective channels and ramps. The socket can then be mounted on a board (27), Fig. 11 (not shown), and connections made to the pins 7. The clamping member or body may be fitted with a resilient clip which engages the body or clamping member respectively. Channels 3 and ramps (13) may be inclined to enhance the wedging action. To secure the socket on its mounting board, a deformable peg (26) is passed through a hole (23) in the body and engages with a snap fit in a hole in the mounting board.

Title: Electronic scanning devices
IPC: H01J37/304
Filed: 1970-12-22
Abstract: 1328976 Optical positioning MARCONI CO Ltd 22 Dec 1970 [15 May 1970] 23620/70 Heading H4D [Also in Division G4] A pattern of square marks, Fig. 2, is applied to a specimen to assist in aligning the specimen in the beam of a scanning electron microscope. The output from the microscope is applied to a display device via an amplifier 1 Fig. 3, and lead 2. An oscillator 7 controls the scanning circuitry 4 of the microscope to give line frequency and field frequency outputs 4L, 4F which are fed to the deflection coils via leads 3X, 3Y. The circuitry 4 also supplies an output to a gate 8 which is gated on when the beam is scanning the specimen to allow through the output from amplifier 1 to a matched filter 9 which passes signals at the frequency corresponding to scanning of a line or column of the marks on the specimen. For aligning the specimen in the x direction, Fig. 2, switches 5, 6, Fig. 3 are first set to their a positions which causes the scanning raster to scan in lines L 1 , L 2 , L 3  parallel to the y-axis. The output of filter 9 is fed to a detector 10 which, when a signal of sufficient strength is passed by filter 9 gates on a gate 11 which passes the signal from a line counter 12 to a comparator 13 where it is compared with a predetermined number set in register 14, and an output is given on one of the lines 131, 132, 133, depending on whether the line being scanned is to the right of, the same as, or to the left of the predetermined line with which it is desired to align the first column of marks. The alignment of the specimen is then coarsely adjusted manually or automatically. Fine adjustment of the specimen is achieved by first switching switches 5, 6 to position b, the scanning raster then scanning in lines H 1 , H 2 , H 3  parallel to the x-axis. The output from filter 9 is fed to a phase comparator 15 where the phase of the signal due to the first line of specimen marks is compared with the phase of a signal from oscillator 7 via a variable delay 16. The output is passed via a low pass filter 17 and manual or automatic adjustment is carried out to finely align the specimen e.g. with scanning line L 3  running down the left-hand vertical edge of the first column of marks. Two circuits such 'as that shown in Fig. 3, one for aligning parallel to the x-axis and the other for aligning parallel to the y-axis may be used or one circuit with additional switches may be used for both x and y-axis alignment.

In the embodiment shown, the insertion limiting means comprises a circumferential shoulder 6 against which the pipes abut. The tapered portions 4 of the fitting 2 which may be of P.V.C. and the plain bore-ends of the pipes 8, 10 receive an application of a solvent to soften the thermoplastic material and the pipes are then pushed on to the fitting. The solvent evaporates to effect a welded joint and an outer layer 12 of reinforced synthetic resin may be applied to enclose the joint. The taper of the tubular section 4 is decreased when a pipe end is received thereon and in another embodiment the taper is decreased upon making the joint to substantially a uniform wall thickness (32) (Fig. 3, not shown). In a further embodiment, a connection fitting (14) (Fig. 2, not shown) has a single tapered section and a shoulder (18) at the end of a pipe section. A further pipe (20) is received on the taper after application of the solvent and an outer casing (22) of reinforced resin, e.g. glass reinforced polyester resin is added. The pipes may be of laminated construction having a glass fibre reinforced polyester resin outer covering over an inner rigid P.V.C. lining.

Filed: 1970-09-16
Abstract: 1336123 Carbon fibres NATIONAL RESEARCH DEVELOPMENT CORP 16 Sept 1970 [16 Sept 1969] 45695/69 Heading C1A [Also in Division B5] As a precursor to carbonization and optional graphitization, synthetic resin fibres, e.g. of polyacrylonitrile, are subjected in a continuous process to stretching, e.g. to 2 x the original length, followed by oxidation at, e.g. 200- 275‹ C., whilst (a) preventing the fibres from shrinking and (b) preventing tension, generated by their tendency to shrink, from being transmitted back to the stretching stage. As described, a flat tow of crimped PAN fibres is spread out and drawn in the entry region of an oxidizing oven. The drawn yarn passes over rollers in the oven which rotate at the same speed as the outlet rollers, this speed being faster than the inlet speed. Frictional contact of the fibres on the rollers allows conditions (a) or (b) above to be met. The oven is resistance heated and has a fan for drawing in air as oxidant. Carbonization and graphitization may be effected in an induction heated cylindrical oven of graphite which is sealed at its ends by argon chambers. The carbonization furnace is purged with argon countercurrent to the fibres to remove decomposition products.

The term "imitation leather" includes materials made from polyamides, polyesters, polyurethanes. The polyurethanes are linear or only slightly branched thermoplastic polyurethanes containing less than 0.2% free isocyanate groups obtained, e.g. by reacting diisocyanates with long-chain diols, such as polyesterglycols, polyether-glycols or polyolefine-glycols, optionally extended with diamines, glycols, amino-alcohols. The aqueous dispersions may be obtained by dispersing in water, in the presence of at least one surface-active agent and/or at least one protective colloid, polyurethanes which are dissolved in an organic medium having at ambient temperature a solubility in water of less than 25% by weight. The aqueous dispersion may be applied during one of the initial stages of finishing the leather, subsequent stages of finishing being carried out with the aid of aqueous dispersions and organic solutions. Dyes and/or pigments may be dissolved and/or dispersed in the dispersion of the solution. The leather may be finished, e.g. by coating with a polyurethane formed in situ by the reaction of a polyol with a polyisocyanate. The surface of the leather may be buffed prior to the treatment. The products may be heat-sealable.

IPC: H01M8/1004
Filed: 1999-09-02
Abstract: Not all gas diffusion structures known to date can guarantee water balance compensation in the fuel cell, protection against drying and prevention of water deposits while simultaneously ensuring even distribution of reaction gases. In the gas diffusion structure, according to the invention, a gradient is produced in terms of gas permeability perpendicular to the membrane by way of a stratified system. This guarantees, at an appropriate operating temperature and appropriate stoichiometry of the reactants, constant and optimal humidification in all points of the membrane by the formed product water. Additional humidification systems can thus be discarded.
