Divided on 397,889. [Class 106 (iii).] In a ticket printing and issuing machine for vehicles and other purposes, in which the tickets are printed and then severed from a roll of paper, the stage printing die is capable of reversal and is associated with printing means to show whether the ticket is issued on an outward or inward journey. The stage printing wheel 22 is fixed to a sleeve 80 carrying also a ratchet wheel 81 which is moved one stage at a time by one of the pawls 82, 83, when the setting lever 17 is depressed. The lever 17 may be set by horizontal adjustment in either of two positions, according to whether the vehicle is travelling on the outward or return journey, so as to rotate the ratchet wheel 81 in the appropriate direction. With this' object, either one or the other of the pawl pivots 90, 91 is held in a slot in the slidable bracket 85 carrying the setting lever 17 so that the other pawl can then operate. The lever 17 and the pawls are raised by a spring. When the lever 17 is set, the printing member 98 is also adjusted so as to print on the ticket an indication as to whether the vehicle is on the outward or return journey, the setting being shown by means of gear wheel 97 through a window 18.

Abstract: 1,195,030. Electrolytic coulometers. BISSETT-BERMAN CORP. Sept. 1, 1967 [Sept. 1, 1966], No.40143/67. Heading G1Q. An electrolytic coulometer has an anode at least the surface of which is of a substance suitable to be electrolytically plated on to the cathode and a cathode whose surface is of a different material, not transportable through the electrolyte but suitable to be plated by the anode surface material. The cathode has a core of material which may or may not be the same as the anode surface material but is different from the cathode surface material, and the cathode surface is a layer which is deposited on this core to a sufficient thickness to make it non-porous and is of uniform texture so that it will plate uniformly in use. Such layer may be produced by electro-plating - not in the coulometer itself but in a suitable plating bath prior to assembly of the coulometer cell. The Specification gives details of suitable processes to produce such a structure. The assembled cell, Fig. 1 (not shown) consists of a casing whose interior surface is the anode and the cathode is fitted into this casing, the latter is filled with a suitable electrolyte, and the completed cell is sealed by a plastic cover. The structure is virtually identical with that of the cell shown in Fig. 1 of Specification 1,144, 732, except that the porous cathode coating of the prior Patent is replaced by a non-porous layer. The manner of use, and applications in which it may be used, are as specified in that Patent. Materials specified are: for the anode surface, silver; for the core of the cathode, silver, brass, copper or nickel; and for the cathode suface gold or platinum. In use - and for certain applications, prior to use - this cathode surface is further plated with silver.

Filed: 1975-10-03
Abstract: 1513880 Vertical antenna THOMSON-CSF 3 Oct 1975 [4 Oct 1974] 40668/75 Heading H4A A vertical antenna is fed at one third of its height and has an operational height of 0À9 wavelengths, whereby the current phase near the feed point is of opposite polarity to the phase nearer the antenna ends. This results in a vertical radiation pattern with relatively samll secondary lobes. In the Fig. 5 embodiment the lower third of pylon 9 acts only as a support for a cylindrical array of parallel, vertical wires 2. The tops of wires 2, and the base of the radiating, upper two-thirds of pylon 9 are fed by co-axial line 41. In the Fig. 4 embodiment the two parts of the pylon are separated by insulator 20 and fed by source 4. The pylon base is earthed directly, or is selectively connected to earth through a reactance 7 or 8. One reactance provides a low impedance for day-time use; the other provides a high impedance for nighttime use, the radiation pattern then facilitating transmission with ionospheric reflection. A series reactance 32 in the upper part of the pylon permits tuning. The antenna of either embodiment may be top-loaded capacitively, and can be used in an array having azimuthal directivity.

[Also in Group XXII] A semi-conductor body with electrodes attached to it has a mass of low melting-point metal cast about it to form a casing. A diode comprising a silicon PN junction wafer soldered at one nickel-plated face to a steel plate and at the other plated face to a copper wire is first coated with insulation 19 by brushing with or dipping in a mixture of liquid epoxy resin, hardener, and titanium dioxide (or mica), and then heat curing the resin. A longitudinally finned casing of tin-lead alloy (63: 37 by weight) or cadmium tin alloy is then cast about the diode in a polytetrafluorethylene mould 21 into which the molten alloy 26 is poured. On cooling the alloy contracts to compress and provide a good thermal contact with the diode. To further improve the heat dissipation the casing after removal from the mould is coated with a suspension of graphite. Alternatively the encased diode may be sealed in an oil-filled aluminium can 29 (Fig. 6). The insulating cover 31 of the can is sealed to it by turning the lip of the can over a resilient ring 32. If one of the terminal wires of the diode may be earthed to the casing metal only the unearthed wire and silicon wafer are coated with insulation so that the casing metal makes direct contact with the steel plate to further improve the heat dissipation. Similar casings may be provided for silicon and germanium transistors, tunnel diodes, and rectifiers.
