Title: Improvements relating to reversible counting apparatus
Inventor: JONES IAN CLIFFORD
IPC: H03K29/00
Filed: 1957-05-07
Abstract: 888,228. Electronic counting apparatus. ELECTRIC & MUSICAL INDUSTRIES Ltd. May 7, 1958 [May 7, 1957], No. 14481/57. Class 106 (1). A reversible electronic counter, particularly adapted for use in a weighing machine producing pulses as the machine moves, comprises at least two multi-position gas discharge tubes 1, 15, the tube 1 receiving on input leads 4 and 5 input pulses phased according to the direction of movement, and stepping the discharge cyclically along the cathodes 3 in a sense depending on the phase, and a coupling between the tubes 1 and 15 including a bi-stable device 8 with inputs from the two cathode resistors 6 and 7 and outputs connected through gates 9 and 10 and phasing delay circuit 14 to the transfer electrodes of tube 15, the gates being controlled by a two-state device 13 responsive to the phase of the input pulses at 4 or 5, or otherwise responsive to the direction of movement of the weighing machine. In this way the discharge reaching electrode " 0 " of tube 1, with cathode resistor 7, from electrode " 9 " with cathode resistor 6 will cause an output from unit 8 which will pass the appropriate gate 9 or 10 to register a carry on tube 15 only if the direction of movement of the weighing-machine represents increasing weight, and correspondingly for movement from electrode " 0 " to electrode " 9."

Abstract: 1,169,126. Portable bridges; bridge-laying vehicles. DR-ING. H.C.F. PORSCHE K.G. 26 March, 1968 [31 March, 1967], No. 14495/68. Heading E1G. In a portable bridge composed of two similar portions A, B which for transport are superposed on a vehicle 1 and for erection are connected end to end before off-loading, the lower portion A is slidably mounted on roller pairs 11, 12 on a pivoted front boom 8 so that it can be slid from under the portion B while the latter is temporarily held raised by supports 22, 24. The supports 22, 24, are then lowered and the aligned bridge portions are connected by transverse power-actuated rods (not shown). The complete bridge is slid along the boom 8 to engage end stops 42, and is lowered into position by hydraulic cylinders 10. Finally, the roller pairs 11, 12 are disengaged through recesses 43. Each bridge portion comprises two spaced road tracks 3, 4 and on its lower chords has inwardly-facing guide channels 7 engaged by spherically-mounted roller pairs 11, 12 pivoted on the central-boom 8. Longitudinal sliding movement is effected by hydraulically-driven gears 18 engaging rack teeth 20 on the channels 7. The support 22 comprises a normallyhorizontal pair of hydraulically-actuated arms carrying rollers 23. The support 24 comprises a hydraulically-actuated boom pivoted to a bracket 30 and comprising spaced pairs of arms carrying transverse locking cylinders 32 by which the boom 24 is detachably pivoted to the portion B.

Title: Improvements in the treatment of polyester fibrous materials and films
Inventor: MCINTYRE JAMES ERIC
IPC: D06M15/17
Filed: 1963-04-11
Abstract: Synthetic polyester filaments, fibres, and fabrics are treated with a compound containing at least one chemical group which confers some desirable property upon the surface of the treated material and at least one alcoholic hydroxyl group, e.g. a poly (oxyethylene) glycol of average molecular weight about 600, and an involatile strong acid, having a first dissociation constant of not less than 10-3 in water at 25 DEG C. and a boiling point above 250 DEG C. at atmospheric pressure, e.g. sulphuric acid, and heated to a temperature and for a time such that chemical groups derived from the compound are attached to the surface of the treated material by newly formed covalent bonds.  The materials treated may comprise polyesters and co-polyesters derived from terephthalic acid and may be linear or slightly cross-linked or branched, e.g. by the incorporation of a tri-or tetrafunctional reactant such as glycerol, pentaerythritol or trimesic acid during manufacture of the polyester.  The group in the applied compound which confers some desirable property upon the surface of the treated material may be a group which gives rise to hydrophilic and anti-static properties, absorbs or transforms ultra violet radiation, repels flames, kills fungi or bacteria or provides increased adhesion to rubbers, rubber latices, paints, inks or dyestuffs.  The compound may also undergo other reactions either within single molecules or between molecules of the compound itself or with some other added component, e.g. another ester or polyester, at the same time as the reaction with the surface of the treated materials so that the chemical group attached to the surface although derived from an alcoholic compound R OH may not be the group RO but may be modified by the production of double bonds or ether or ester linkages.  If the compound is susceptible to oxidation an antioxidant, e.g. thio bis-(3-methyl-6-t-butyl phenol) may be included in the treating composition.

Title: Improvements in or relating to the coating of diamonds and other precious stones
IPC: C23C14/02
Filed: 1945-06-08
Abstract: A process for coating diamonds and like precious stones with a metal or refractory material consists in (a) cleaning chemically, e.g. with carbon tetrachloride followed by aqua regia; (b) cleaning "physically" by subjecting to ionic bombardment in vacuo; (c) depositing the desired metal &c. by vaporization or sputtering whilst still in vacuo.  Diamonds and diamond powder thus treated can be imbedded in a metal, carbide or ceramic matrix for use as a cutting or grinding tool.  A vacuum of 0.1-0.005mm. of mercury is used, whilst a potential of at least 1,000 volts both for ionic bombardment and sputtering, is employed.  Copper, aluminium, beryllium, zinc, cobalt, silver, nickel, iron, chromium, silica, calcium fluoride may be deposited by vaporization; silver, nickel, copper, platinum, tungsten and cobalt by sputtering.  When sputtering is employed, the electrodes (e.g. aluminium) used for ionic bombardment and those used for the sputtering, may be present together in the treating chamber. A further coating of the same or other metal may be subsequently built up by electro-plating, dipping or spraying.

[Class 60] [See also Group XXII] In an electric tracer for controlling the feed move ment in grinding machines having two feed motions at right angles to each other the tracer 1 is pivoted at 2 on the tool-slide 3<1> and acts by its rear end 3 on bevellec surfaces on a plunger 4 which engages a pivote( switch lever 5. Contacts 6 on the lever 5 are adapted to engage contacts 7, 8 on levers 9, 10 pivoted to the tool slide and biassed towards each other by a spring a. Contacts 11, 12 on the levers 9, 10 are adapted to engage a fixed contact 13 on the tool slide. The contacts are connected through relays to electromagnetic clutches, the contacts 6, 7, 8 controlling the transverse feed through a bevel reversing gear and the contacts 11, 12, 13 controlling the longitudinal feed. A magnetic brake is provided in each feed to stop the feed immediately the contacts are separated, and the longitudinal feed is effected through worm and spur gearing to a rack-and-pinion whilst the transverse feed is by worm and spur gearing to a lead screw, change wheels being provided in each train. The contacts 6, 8 are normally closed by the spring 8<1>, thus opening the contacts 12, 13 and allowing the transverse feed alone to operate. Pressure on the tracer 1 permits the contacts 12, 13 to close, thus operating the transverse and longitudinal feeds together until increased pressure opens the contacts 6, 8 and allows the longitudinal feed alone to operate. Greater pressure on the tracer causes the contacts 6, 7 to close, thus operating the longitudinal and transverse feeds, and still greater pressure opens the contacts 11, 13, thus allowing the transverse reverse feed to operate alone.
