Title: Improvements in and relating to apparatus for high tension electric transmission lines
IPC: H02G7/00
Filed: 1930-05-21
Abstract: 342,234. Transmission lines. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London.- (Assignees of Hawley, K. A. ; P.O. Box A, Maryland Trust Building, Baltimore, U.S.A.) May 21, 1930, No. 15655. Convention date, May 21, 1929. Drawings to Specification. [Class 38 (iv).] The metallic supports of the insulators of high tension conductors on a wooden pole line are bonded together and fuses are interposed in the bonding connections. All may be connected to a common point and this point may be connected to the metallic support or supports of the earth or static wire or wires or, by a fuse, to the grounding wire, which is disposed away from the pole, or to both. The stay wires are insulated by insulators of the wood stick type having a greater puncture and leakage distance than the goose-egg type. On the occurrence of a discharge between conductors, or to ground, fuses blow and the insulation resistance of the wooden structure is interposed to stop the discharge. The normal presence of the bonding connection prevents the ignition of the pole by leakage current over dirty insulators. The fuses used are preferably of the expulsion type.

Abstract: 1371500 Multiplex pulse signalling NISSAN MOTOR CO Ltd 3 Dec 1971 [21 April 1971 29 May 1971] 15706/74 Divided out of 1371499 Heading H4L A time division multiplex system of the type disclosed in the parent Specification is provided with a modified synchronizing arrangement. A common clock pulse generator produces sequences of clock pulses as before, Fig. 3a, and these are combined with a pseudo-random sequence (b) to produce the repetitive sequence (c) which is transmitted over the reference signal line 13, Fig. 2. At the transmitter 14 the reference pulse sequence is separated at 91 into clock pulses and the pseudo-random sequence and supplied to inputs 92, 93, respectively, of a shift register 94. The three outputs of the shift register, which are connected to a logic circuit 102, produce the pseudo-random sequence delayed by one, two and three clock pulse periods respectively and the logic circuit is arranged to provide an output pulse only at the time position allotted to that transmitter in response thereto. The output of circuit 102 opens the gate 104 to pass the input signal to line 18. The receiver 19 operates in a similar manner to control the gate 124 for the signal received via line 18. The receiver may also include a circuit for checking the pseudorandom sequence and disabling the receiver output if the incorrect sequence is received, Fig. 9 (not shown).

Patent GB-641526-A (GB)
Title: Improvements in windshield wipers
Inventor: BODDY JOHN
IPC: B60S1/36
Filed: 1948-06-14
Abstract: 641,526. Windscreen-cleaners. TRICOFOLBERTH, Ltd. June 14, 1948, No. 15987. [Class 138(i)] A windshield wiper arm comprises a mounting socket, an inner arm portion pivotally connected to the mounting socket, an outer arm portion which is movable relatively to the inner portion to vary the effective length of the arm, and a spring which urges the arm towards the windshield when the mounting socket is mounted on its actuating shaft, and has means whereby the pressure with which the arm is urged towards the windshield by the spring is automatically increased when the arm is lengthened, this increase in pressure being additional to any slight increase which may be due to the arm being rotated slightly about its pivot. The thickness of the outer arm 8, Fig. 1, gradually increases towards its inner end. Notches 9 on the arm 8 co-operate with one end 10 of a leaf-spring 11 supported intermediate its ends by a pin 12 carried by the inner arm 5. As the arm 8 is withdrawn from the arm 5 to alter the effective length of the wiper arm 1, the tension of the spring 11 is correspondingly increased. In another embodiment, Fig. 2, the ends of a coiled spring 19 are connected to a pin 20 on the mounting head 6 and at 18 to a wedge 17 co-operating between a fixed ramp 16 secured to the inner arm 5, and the outer arm 8 which is provided at its inner end with an upwardly bent portion 15. The distance between the anchoring points 18 and 20 is dependent on position of the arm 8 relative to the arm 5. The tension of the spring 19 is therefore increased as the effective length of the wiper arm is increased. In lieu of the bent portion 15, the inner end of the arm 8 may be provided with a wedge-shaped block in order to provide a greater supporting surface for the arm. To adjust the position of the arm 8 the tension of the spring 19 is first released by removing the wiper arm from its actuating spindle and turning the head 6 relative to the arm 5 so that the point 20 is moved nearer the point 18. Alternatively, the same object may be achieved by removing the wiper blade from the arm 8.

Title: Process for making oxide cathodes
Inventor: WILLIAMS PAUL DEWITT
IPC: H01J9/04
Filed: 1968-04-03
Abstract: 1,205,116. Cathode materials and processing. VARIAN ASSOCIATES. 3 April, 1968 [3 April, 1967], No. 16079/68. Heading H1D. A process for making an oxide cathode, in which the emissive material comprises a mixture of alkaline earth oxide and a metal having a vapour pressure not exceeding that of iron, e.g. Ni, W, Co, Pt, Fe or Rh, includes the steps of producing a dispersion of alkaline earth metal carbonate in an aqueous solution of a soluble salt of the said metal and providing a composition including the carbonate and the metal salt in a lacquer which is coated on the cathode base. The composition may be formed either by using a water soluble lacquer or by first evaporating the water from the aqueous solution, e.g. by heating in air at 90‹ C., to leave the carbonate crystals coated with the metal salt and dispersing the coated crystals in an organic lacquer, e.g. nitrocellulose or butyl methacrylate lacquer. In an example, nickel acetate is mixed with the alkaline earth metal carbonate in the weight ratio of 1 to 10 respectively, the carbonate comprising equal parts by weight of barium and strontium carbonate, and, after evaporating the water, the coated crystals may be dispersed in nitrocellulose by a ball-milling action. Preferably the cathode base is formed of the same metal as is dispersed in the carbonate.

Title: Implement-lifting and draft-regulating means for a tractor
Inventor: WIGGINTON RALPH
IPC: A01B63/112
Filed: 1963-04-24
Abstract: 1,013,010. Tractor power lift mechanisms. STANDARD MOTOR CO. Ltd. April 14, 1964 [April 24, 1963], No. 16097/63. Heading A1P. In a tractor power lift mechanism a manual lever 20 is used to set the level of draft control and also, operating through another sector of its movement, to operate a position control mechanism. The lever 20 is rigid with shaft 21 which has an eccentric pin 22 to move a two-armed lever 23, 24 whereby the main control slide valve 27 is actuated. Follow-up is provided by a cam 30 on rockshaft 11 engaging lever 24. For draft control the spring 75 is compressed by the upper link of the linkage and lever 20 is set so that the lever 23 will engage cam 72. For the 'raise' position the spring 28 moves valve 27 upwards to connect conduits 36 and 37 through which fluid is supplied by a pump 47. The fluid then passes through non-return valve 46, radial parts 59 in a piston valve 60, conduit 44, two way valve 64 and conduit 42 to the main cylinder 17. In the 'lower' position valve 27 is moved downwards to open conduit 38 to exhaust, the fluid passing through piston valve 60 which acts to keep the exhaust pressure constant by moving to restrict the parts 59 depending on the pressure in conduit 38. Piston valve 49 opens to divert the pump output to exhaust through conduit 52 if pressure builds up in conduit 48. When valve 49 is closed both sides of the valve are subjected to pump pressure but if an excess pressure arises in the supply conduits valve 57 is moved to connect one side of valve 49 to exhaust whereby this valve is opened to relieve the pressure in the system.

Title: Improvements in or relating to fuel oils and the combustion of fuel oils
Inventor: TAYLOR TRISTRAM ALLAN
IPC: C10L1/10
Filed: 1950-06-28
Abstract: To a vanadium-containing fuel oil, which on combustion yields ash containing vanadium pentoxide which is liable to cause corrosion of metallic parts exposed to the combustion products of the oil at elevated temperatures, there is added, for the purpose of reducing this corrosion, a substance with which the vanadium pentoxide will react in preference to said metallic parts.  The substance may be a metal of Group II of the Periodic Table, an oxide thereof or a compound yielding an oxide thereof at combustion temperatures. Specific substances mentioned are calcium, magnesium, zinc, their oxides and zinc naphthenate. Other organic compounds such as the oleate, stearate or linoleate of the selected metal may be employed, but it is preferred to add the oxide, hydroxide or carbonate of the selected metal dissolved or suspended in oil, water or other liquid medium.  The fuel oil may be a residual oil and the addition of zinc naphthenate to a Curacao fuel oil (which contains sodium and nickel in addition to vanadium) is mentioned.  The residual oils may also contain sulphur, but calcium and its compounds should only be added to a sulphur-free oil or in cases where some means of removing the sulphur is used.  It is believed that the metal oxide additive, or the metal oxide formed by oxidation of the metal additive or by decomposition of the added metal compound, reacts with the vanadium pentoxide content of the ash, resulting from the combustion of the fuel oil, to form a stable vanadate.  According to the Provisional Specification, the added substance may be nickel oxide; the hydroxide, carbonate, oleate, stearate, linoleate or naphthenate of calcium; iron, cobalt or chromium or their oxides or oxide-yielding compounds; and substances which would give rise, during the combustion of the vanadium-containing fuel oil, to vanadium silicate. Specifications 639,468, [Group XII], and 702,215, [Group XI], are referred to.  Reference has been directed by the Comptroller to Specifications 667,371, 689,579 and 697,101.
