Title: Improvements in or relating to electron tubes and method of making same
IPC: H01J19/30
Filed: 1946-07-05
Abstract: 614,105. Electrode materials and processing. ABBEY, A. (Eitel-McCullough, Inc.). July 5, 1946, No. 20188. Drawings to Specification. [Class 39 (i)] [Also in Group XV] A method of making a non-emissive electrode such as a grid comprises applying to a metallic core a coating of finely divided particles of two or more refractory metals and oxygen combined as an oxide of at least one of the metals, formed by partly reducing a mixture of oxides of the metals, and uniting the particles by sintering them to form a continuous sheath about the core. The core may be of tantalum or molybdenum, and the coating metals are tantalum, tungsten, molybdenum, niobium, vanadium, chromium, titanium, zirconium or beryllium. The preferred mixture comprises 90 per cent tantalum pentoxide and 10 per cent tungsten trioxide ; this is fired in a reducing atmosphere and then mixed with a binder which may be a nitrocellulose derivative mixed with amyl acetate. The coating is then applied to the grid which is prefired by heating in an oxygen-free atmosphere prior to mounting it in the valve envelope. In an alternative process the oxides are not prefired but are coated on the grid and reduced during the sintering process.

Title: Improvements relating to centralized lubrication systems
IPC: B60R17/02
Filed: 1927-07-29
Abstract: 275,259. Tecalemit, Ltd., (Assignees of Soc. Anon. des Etablissements TÚcalÚmit). July 31, 1926, [Convention date]. Actuating by electric power.-In a pump for a lubricating system for motor-vehicles, the pump plunger 9 is secured to the core 10 of an electromagnet, in the circuit of the winding 11 of which are included a manually operated switch 18 and an automatic switch 18<a>, which latter is in mechanical connection with the plunger and is actuated at the end of each suction or discharge stroke so as to ensure the continuous operation of the pump so long as the switch 18 is kept closed. The switches may operate through a re-lay switch 17. The pump draws lubricant from a renewable container 1 through a pipe 2<1> which projects slightly above the base of the container so as to prevent the entrance of impurities into the pipe, and discharges through a pipe 21 having branches leading to the parts to be lubricated. The automatic switch comprises an insulated ring 43 carried by a spring 42 secured to a sleeve 35 slidable on a fixed tube 36 projecting into a recess in the core 10. A pin 40 carried by the core 10 engages a groove 41 in the sleeve, the movement of the sleeve being limited bv a pin 38. The ring 43 normally closes the circuit, but when the circuit is energized by closing the switch 18, the core is drawn into the winding and, at the end of the stroke, the pin 40 causes the sleeve to move, thus breaking the circuit. A spring 13 then effects the return stroke, the pin 40 causes the sleeve to move to close the circuit, and the operation is repeated. According to the Specification as open to inspection under Sect. 91 (3) (a) the automatic switch may be omitted. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to navigation aiding radio transmitters
IPC: G01S1/02
Filed: 1939-07-12
Abstract: 532,122. Directive wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., GREEN, E., and DAVIS. N. E. July 12, 1939, No. 20349. [Class 40 (v)] Relates to means for ensuring a clear-cut keying action, and for balancing or neutralising the residual capacities, in a condenser-switched equisignal beam-transmitter of the kind described in Specification 516,149. Instead of using coupling condensers with different arcuate areas of overlap, two identical rotary vanes E, T, Fig. 1, co-operate with fixed vanes E<SP>1</SP>, TI. The moving vanes are driven by a shaft S which is caused by a cam (Figs. 4 and 5, not shown) to oscillate rapidly, from one position giving maximum coupling with a transmitter A, to another position giving maximum coupling with a transmitter A<SP>1</SP>; the " dwell " in each case corresponds to the required Morse E and T signals, so as to give a clear-cut change-over. In Fig. 8 any residual capacity between the stators 10, 11 is balanced or neutralised by a set of inductances, of which coil 1 is connected across the condensers 9, 11 and is adjusted to resonate with and so block out any residual capacity coupling between stator 11 and rotor 12; coil 2 being shunted across stators 11 and 13 forms a rejector circuit for any residual capacity between them ; whilst the coils 3 and 4 play similar roles. Under these conditions, when the rotor 8 is out of the stator 11, no energy can reach its associated aerial by undesired capacity coupling, and the same applies to rotor 9. The number of coils may be reduced to two, one across the condenser E, E<SP>1</SP>, Fig. 1, and the other across the condenser T, T<SP>1</SP>.

Filed: 1927-08-02
Abstract: 276,321. Siemens - Schuckertwerke Akt.-Ges., (Assignees of Siemens-Schuckertwerke Ges.). Aug. 19, 1926, [Convention date]. Counters for articles. - Means for registering the stocks in a warehouse, or stock of parts in course of preparation in a workshop, comprises two counting mechanisms actuated by the passage of an article to or from the warehouse to indicate the total arrivals and departures and a counting mechanism for automatically indicating the difference between arrivals and departures. The counters may be actuated electromagnetically by passing the articles over a contact device to cause a current impulse to be sent to the electromagnet of the counter. Two counting mechanisms only may be provided, in which case they may be so arranged that the resetting of the departure counter operates to withdraw that number from the reading of the arrivals counter to show the difference. In the form shown the incoming units of stock cause a contact lever 8 to close the circuit of the actuating electromagnet of the arrivals counting mechanism 2 and at the same time that of an electromagnet 17 actuating a ratchet wheel of the counter 1. Outgoing units of stock through a contact lever 4 actuates a departures counting mechanism 3 and energizes an electromagnet 18 adapted to operate the counter in a direction opposite to that of the electromagnet 17 so that the difference between the arrivals and departures is indicated on the counter 1. Specifications 3158/08, 22833/12, and 194,656 are referred to.

Title: Improvements in or relating to a method of and apparatus for applying variegated or "jazz" colourings to the surfaces of articles
IPC: B44F1/14
Filed: 1933-07-21
Abstract: <PICT:0422925/III/1> <PICT:0422925/III/2> In a method of applying variegated or "jazz" colourings to the surfaces of articles by dipping the articles into a film of colouring materials floating upon a continuously flowing liquid, the liquid flow is produced as a surface flow across a relatively still body of liquid and the articles are passed through the flowing liquid surface into the relatively still body of liquid. A tank 10, 11, 12 is supplied with a surface stream of water by the perforated pipe 14, and colours may be shaken from bottles 24 by rocking the treadle 26.  An air current from the blower 35 may be directed on to the liquid surface to assist the liquid flow and to agitate and mix the colours.  An article B, to be coloured, is passed through the flowing surface into the still liquid at the deep end 11 of the tank, and may be removed therefrom by passing it under the baffle 13 into the portion 12 of the tank. This may be done by hand, or by the rotating wheel shown in Fig. 5, and in this latter case the coated articles may be released from their holders 39 by the action of a cam 42.

Abstract: 888,490. Resistance measurement. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 10, 1959 [June 27, 1958], No. 20738/58. Class 37. A rotor temperature indicating apparatus for a dynamo-electric machine in which an ohmmeter calibrated in temperature has a current coil connected through shunt leads to a shunt resistor in series with the rotor and a voltage coil connected between one end of the current coil and the rotor terminal remote from the shunt resistor, comprises electrical resistance means so connected and proportioned relatively to the remaining components that the shunt leads carry currents of approximately the same magnitude to produce across such leads voltages whose algebraic sum in the closed circuit of the current coil and the shunt approximates to zero. An ohmmeter arrangement indicating the resistance and thus the operating temperature of the wound rotor R comprises a shunt S in series with the excitation thereof connected through shunt leads of resistance R2 and R3 in series with a swamp resistance R1 to the current coil C of a permanent magnet crosscoil meter whose voltage coil V (similar to the current coil) is connected from the junction of C and R2 through a swamp resistance R4 to the rotor terminal opposite to the shunt. An equalizing resistance R5 is connected across the voltage coil of such value that currents of approximately similar magnitudes flow in shunt leads R2, R3 in such directions that the algebraic sum of the P.D's. thereacross is approximately zero as regards the closed circuit including the current coil C, so that the current in the latter is independent of the resistances of the shunt leads; enabling a smaller value of shunt resistance to be employed and removing errors due to temperature variations of the shunt leads. Specification 615,597 is referred to.

IPC: F02K9/44
Filed: 1968-05-02
Abstract: 1,224,775. Deflecting propulsive jets. ROLLS-ROYCE Ltd. 2 May, 1969 [2 May, 1968], No. 20968/68. Heading B7G. [Also in Division F1] A rocket engine has a combustion chamber 6 which communicates with an expansion nozzle 7, hydraulically operated rams 11 for angularly adjusting the nozzle 7 with respect to the combustion chamber 6, and a liquid oxidant tank 3 and aliquid fuel tank 4 which communicate with the combustion chamber 6 by way of rupturable sealing means 30, 31. A gas generator chamber 12 mounted within the tank 3 contains a solid propellant 13 which, when ignited by means of an igniter 14, produces propulsive gases which rupture an annular burster band 16 sealing an array of annular inlet ports 15 of the tank 3, also an annular burster band 27 sealing an array of annular inlet ports 26 of the tank 4. By this means the liquid fuel and liquid oxidant are pressurized. Mounted within the tank 4 is an axially movable mechanism 20 comprising upstream and downstream parts 21, 22 interconnected by a tubular annular member 23. The tanks 3, 4 each has a plurality of angularly spaced-apart outlets 30, 31 normally closed at their radially inner ends but recessed so as to weaken them and mounted within rupturing members 32, 33 which constitute portions of the parts 21, 22. The mechanism 20 which is normally held in the inoperative position by means of a retaining spring (not shown) is propelled downstream on ignition of the propellant 13 with the result that the members 32, 33 rupture the radially inner ends of the outlets 30, 31. The outlets 30, 31 are brought into communication with ports 34, 35 in the mechanism 20, whereby the fuel and oxidant are introduced axially into the combustion chamber 6 via injectors 38. The port 35 communicates with a passage 40 which, when the parts are in their operative position, communicates with a duct 41, which in turn communicates via a valve mechanism (not shown) with the rams 11. The valve mechanism is adapted to receive telemetry signals such that predetermined rams 11 will receive the pressurized fuel from the duct 41 so that the nozzle 7 will be disposed in a desired position. The nozzle 7 is mounted within a hydrodynamic spherical bearing 10 which is arranged (by means not shown) to receive propellant which has passed through the outlets 30, 31.

Abstract: 405,266. Mounting engines &c. FORD MOTOR CO., Ltd., 88, Regent Street, London. July 25, 1932, No 20978. Convention date, May 2. [Classes 79 (iii) and 79 (v).] The engine unit of a motor road vehicle is mounted at its front and rear ends upon resilient supports which permit relative universal movements between the engine and the chassis frame subject, however, to restraint in the longitudinal direction of the vehicle which is provided by coupling the engine to the frame by radius rods 42 substantially parallel to the engine shaft. At the front end, the engine is mounted upon rubber cushions 28 carried by a resilient U- or saddle-shaped plate 30 bolted, in conjunction with the front cross frame member 11, to a transverse main chassis spring whilst, at the rear end, the engine mounting comprises a resilient ring 16 placed under compression in the longitudinal direction of the vehicle. The rubber cushions 28, vulcanized to inner and outer sleeves 26, 27, Fig. 8, are secured by nuts on vertical bolts 32 integral with the ends of the plate 30 and are retained by snap rings 29 in sockets or seatings 24<a> in a bracket 24 bolted to the face of the engine crank case. Alternatively, as shown in Fig. 9, the cushioning members may be centrally bolted to a flange on the bracket 24, the outer sleeve 27 of each, in this case, being formed with lugs or ears 35 to engage the end and sides of the plate 30. The rear mounting ring 16 is arranged around the transmission housing, embracing and being vulcanized to the edge of a circular opening in a plate 15 bolted to the transverse frame member 13 which is correspondingly apertured. A cylindrically dished plate 18 with a radial flange 19 embraces and compresses the ring 16 in the axial direction when secured to the transmission housing by screws 20. Before assembly, however, bolts 21 are inserted through the flange 19 with their shanks projecting rearwardly, slots or gaps 23 being provided in the ring 16 to accommodate their heads. The heads serve to restrain the ring from torsional displacements whilst the bolts form the means of attachment of the usual universal joint housing 22. The engine and rear axle are rigidly connected by the torque tube 41. The rods 42 are secured at their ends respectively to the engine flywheel housing 40 and the frame member 13 and prevent longitudinal movement of the engine relatively to the frame without restricting relative movement in any other direction. The brake pedal 36, which is pivoted to the forward face of the transverse frame member 13, is connected through a link 37 to a brake cross shaft 38 pivotally mounted on the rear face of the member 13, brake operating rods 39 extending from the shaft 38 both forwardly and rearwardly so that they are drawn inwards upon depression of the pedal 36 thereby applying the brakes simultaneously on all four wheels.
