Title: The oxidation of saturated hydrocarbons
Inventor: GARDNER CYRIL
IPC: C07C29/48
Filed: 1964-12-21
Abstract: Aliphatic or cycloaliphatic saturated hydrocarbons are oxidized by treating with a gas mixture of molecular oxygen and ozone, n-Hexane, n-octane, cyclobutane, cyclopentane, cyclohexane, cycloheptane, cyclo-octane and homologues thereof are mentioned and the gas mixture may be passed through the liquid hydrocarbon, in the presence, if desired, of manganese or cobalt salts as catalysts.

Abstract: 1311138 Power division networks CENTRE NATIONAL D'ETUDES SPATIALES 10 Nov 1970 [24 Dec 1969] 53457/70 Heading H1W [Also in Division H4] An H.F. switching device in which a single transmission path may be coupled to either of two other transmission paths, or to both of said other paths simultaneously, comprises two switching diodes 1, 2 which are respectively connected at distances of #/4 along the other lines, from the branching point A of the three lines (# = wavelength at mid-frequency of the operating band). The diodes are respectively connected to earth through capacitors 3, 4 and each may be biased either forwardly or backwardly by means of a switch 5. When a diode is non-conductive it has no effect upon the transmission of energy along the associated other line, but when it is conductive a high impedance is returned to the point A, and the associated other line is effectively blocked. The diodes may be of the P.I.N. type, and the switching and distributing assembly may be embodied in a three-plate circuit with a suitable dielectric substrate. An arrangement is described (Fig. 2, not shown) in which four radiating elements distributed across a convex surface are connected in pairs to two switching devices of the type shown in Fig. 1. The outputs from these devices are connected through a third switching device to a single feeder, which may thus be connected to any combination of the radiating elements. In another arrangement, five pairs of radiating elements are distributed across the two surfaces of a dihedron, and are connected to a single feeder through nine switching devices (Fig. 3, not shown).

Title: Improvements in fault registration systems
IPC: H04M3/36
Filed: 1965-12-23
Abstract: 1,095,909. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Dec. 23, 1965 [Dec. 24, 1964], No. 54586/65. Heading H4K. A system, in which the state of faulty equipment is set up in a fault register automatically on occurrence of the fault, produces a punched card record for selected faults as indicated by a reference store containing, (a) the identity of the faults for which a punched card is required when the system normally produces no such record, or (b) the identity of the faults for which a punched card record is not required when the system normally produces such a record. The fault register is set selectively to produce or not produce a punched card record for each fault that occurs and the reference store, containing an appropriate catalogue of faults with which each fault appearing in the register is compared, may be selectively associated with the register to either sanction or prohibit the production of a punched card record for any fault in the catalogue. The reference store may comprise a set of plug boards, each of which is set up in a configuration corresponding to the punched card record relating to a fault, or the store may comprise a set of punched card readers into which the punched cards of selected faults are inserted. Instead of working automatically through the fault conditions as they occur with consequent busying and release of the faulty circuits when a record is taken, the fault register may be conditioned to maintain itself in association with a fault present in the catalogue by means of which it is identified by an attendant who releases the register for further action. The reference store may contain the identity of particular calling or called lines to either include or exclude punched card records of particular faults associated with these lines. The use of the reference store to limit the production of punched card records is said to have advantage when fault conditions are numerous, as when setting up an exchange, or when the fault is attributable to a known cause and would encumber the analysis of the punched card records.

Abstract: 1448478 Flanging metal plates PROTOCOL ENG Ltd 18 Nov 1974 [28 Nov 1973] 55244/73 Heading B3E The edge of a metallic plate, e.g. a printing plate, is flanged over the edge of a former by pressing a pad of resilient flowable material against the plate adjacent the former edge, whilst turning the pad around the former edge. In the embodiment of Fig. 1, the former 5 includes operative edges 7, 8, at each of which a plate resting on the former will be flanged, though most of the apparatus is shown for edge 8 only. The pad (26, Figs. 4a and 4c) is of a urethane elastomer or rubber and is mounted in the channel of a beam 21 extending between pivots 23 on levers 14, 15 rockable about fixed pivots 17 by double acting pneumatic motors 19. The beam 21 is pivotable relative to the levers by double acting pneumatic motors 36. In use, a plate is placed on former 5 so that apertures in the plate register with pins 11. The levers 14, 15 are then pivoted so that pad 26 clamps the plate 6 on the former, as in Fig. 4a. The pins 11 are then withdrawn by motors 13, and motors 36 operated to swing the pads round and flange the plate, as in Fig. 4c. The pad will flow at 26a into a recess 24a in the beam 21. A similar flanging operation occurs simultaneously at edge 7, and then the edges 7, 8 are moved towards each other by a wedge mechanism 28 to facilitate removal of the flanged plate. Closure of two transparent guards 31, 32 after positioning of the plate may initiate the sequence of events which then continues automatically. After removal of the plate, a reset button 35 can be actuated to restore the initial conditions. In a modification, Figs. 7-19 (not shown), removal of the flanged plate is automatic after edges 7 and 8 have been moved towards each other, by raising of a set of rollers through slots in former 5 to engage the plate, and driving of the rollers to feed the plate out. Raising, driving, and lowering of the rollers is performed automatically. In another embodiment, Fig. 10 (not shown), the movement of pins 11, the clamping of the plate by the pad, and the turning of the pad are effected by three manual drives.
