IPC: E02F3/92
Filed: 1970-12-08
Abstract: 1329113 Trench excavators TAKENAKA KOMUTEN Co Ltd 8 Dec 1970 [13 Dec 1969] 58322/70 Heading E1F Material excavated by the pair of bladed cutter drums 14, 15 rotatably mounted in the open bottom end of a box type casing 11 of an excavator suitable for trenching passes upwards between the drum to the vicinity of an intake port of a suction port, the port being defined by the union of the pipe 8 and the bell-mouthed upper portions of casings partially surrounding the cutter.

Title: Dynamic display systems
IPC: G06F3/147
Filed: 1972-12-20
Abstract: 1382728 Control of displays HITACHI Ltd 20 Dec 1972 [24 Dec 1971] 58790/72 Heading G4H An electronic desk calculator comprises shift registers Rx1 Rx2, RY an adder AD and an OR gate OG connected to the registers in such a way that a calculated result may be repeatedly fed to a display device driving system DS from Rx1, Rx2 in turn in order to enhance the brightness of the display. In order to multiply a first operand 01 by a second 02, 01 is entered in Rx and is circulated through Rx1, Rx2 and AD. When 02 is entered, 01 is shifted from Rx2 to RY. Repeated addition of 01 to 02 is then effected by AD: the intermediate result and the number of additions still to be performed are circulated until finally Rx1, Rx2 respectively contain zeros and the calculated result. OG is then enabled and each (4-bit) digit of the result is fed to OG as it leaves Rx2 (OG receiving Os from Rxl) until the result has circulated from Rx2 through AD and into Rx1: OG then receives each digit in turn from Rx1 and Os from Rx2. This procedure is repeated as the result and the zeros are circulated, and it is stated that it doubles the duty cycle of the drive signals for the display device, thus enhancing the brightness of the display. The operands may also be displayed in the same way when they are circulated through Rxl and Rx2.

Filed: 1969-12-02
Abstract: 1291471 Voltage variable resistors MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 2 Dec 1969 [2 Dec 1968] 58859/69 Heading H1K A voltage variable diode resistor the current in which is represented by the expression (V/C)<SP>n</SP> consists of a sintered body principally of zinc oxide but including from 0À05-10 mol. per cent of Ga 2 O 3  and possibly also 0À05-8 mol. per cent of Bi 2 O 3  carrying at least one non-ohmic contact, preferably of silver paint. The value of C is increased if both contacts are non-ohmic. Stability of the characteristics in temperature cycling and electric load tests is enhanced by using for the electrodes specified mixtures of silver, in elemental or heat-reducible form, silica, boric oxide and lead or bismuth oxide, especially when traces of cobalt and/or manganese oxide are included in the mixtures. The mixture is applied as a paste comprising epoxy, vinyl or phenol resin in an organic solvent and fired at 300-850‹ C. in an oxidizing atmosphere. Protection against moisture is afforded by potting in or coating with phenol or epoxy resin. When one electrode is ohmic it may consist of one of Al, Zn, Sn, In, Ni or Cu applied by vapour deposition, spraying or plating and lead wires can be attached with soft solder or silver paste. Reduced resistivity can be obtained by carrying out sintering in nitrogen or argon and by quenching thereafter in air. Numerous examples of body and electrode compositions are given.

Title: Method of forming raised figures on a dial plate
IPC: B44C3/04
Filed: 1979-02-05
Abstract: The invention provides a method of forming raised characters on a dial plate 8. A hole 1 is produced in the dial plate 8 at the desired location of each character, and the dial plate is then prefinished. To form the characters, the dial plate is placed in a mould, one half 6 of which is formed with a plurality of cavities 7 each in the shape of one of the desired characters. The other half 2 of the mould is provided with a channel 3 which follows a path corresponding to the various character cavities. The dial plate is placed in the mould with the holes in register with the channel and the respective cavities, and synthetic resin material is injected into the channel and hence through the holes into the various character cavities. When the dial plate is removed from the mould, it will be found that the synthetic resin characters have been formed on one side of the plate, and a ring, or the like, corresponding to the channel has been formed on the other side of the plate. The characters are joined to the ring by synthetic resin material extending through the various holes in the plate. <IMAGE>

Title: Improvements in or Relating to Support Means for Pneumatic Tyre and Wheel Rim Assemblies
IPC: B60C17/04
Filed: 1979-03-09
Abstract: A pneumatic tyre and wheel rim assembly comprises support means (3) which extends circumferentially around the rim (2) between the bead seats (9) to support the tyre (1) when in a deflated condition, and which is rotatable relative to the rim (2) when the tyre is in a deflated condition, and lubrication means (22) provided to release lubricant to facilitate said relative rotation. The lubrication means (22) comprises a sealed container (24) located in a recess (23) in the support means (3) and having a nipple (27) which ruptures to release lubricant between the radially inner surface of the support means (3) and a confronting running surface (21) on the rim (2) when the support means rotates relative to the rim. As a result frictional resistance to relative rotation between the support means (3) and the rim (2) is substantially reduced whilst undesirable distribution of the lubricant over the inner surface of the tyre (1) which could result in undesirable slippage occurring between the tyre (1) and support means (3) is substantially avoided. <IMAGE>
