Title: Improvements in or relating to direction of wind indicating apparatus
IPC: G01P13/02
Filed: 1945-09-25
Abstract: 599,942. Heating wind direction apparatus by electromagnetic induction. ELECTRIC RESISTANCE FURNACE CO., Ltd., MARSH, J. H., GENERAL AIRCRAFT, Ltd., and HARVEY, W. W. Sept. 25, 1945, No. 24828. [Class 39 (iii)] [Also in Group XXXV] A wind direction indicating apparatus of the type described in Specification 502,022 has a self-igniting induction heater comprising a primary 15 and a single-turn, short-circuited secondary 16 which also forms the heating chamber. The space between the windings is filled with heat-insulating material 24 and the pipe 30 containing oil to be vaporized passes through the secondary 16 which is thickened where additional heat is required by tubes 32, 33. The magnetic circuit 17, 17<1> is completed by bars of irreversible ferro-magnetic material 18, 18<1>, which pass through the secondary or heating chamber 16, the arrangement being such that when the regulating bars reach a temperature at which their magnetic properties are reduced, the unit takes a lower power input sufficient only to maintain the requisite temperature for vaporizing the required quantity of fuel.

Title: Improvements in or relating to sensing devices for ultrasonic inspection of rails
IPC: B61K9/10
Filed: 1962-06-28
Abstract: 941,457. Ultrasonic testing. ROCJAR ELECTRONIQUE. June 28, 1962 [July 8, 1961], No. 24854/62. Heading H4D. In an arrangement utilizing ultrasonic energy for inspecting rails a pair of transmitting transducers 2, 4 and an associated pair of receiving transducers 3, 5 (Figs. 2 and 3) respectively are so arranged on a carrier 6 with respect to a rail 1 that the energy transmitted from each transducer 2, 4 is received by its associated receiving transducers 3, 5 after reflection from that one of the two inclined faces 7, 8 of the rail heat which lies on the opposite side of the vertical plane of symmetry to that on which the transmitting transducer is positioned. Whilst two pairs of transducers are preferably employed a single pair only, such as 2, 3, Fig. 1, may be employed. An advantage of this arrangement over known devices in which the ultrasonic energy is transmitted vertically downwards is the absence of echoes due to reflections from the lower face of the rail foot.

Abstract: 462,323. Wireless receiving systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Sept. 6, 1935, No. 24914. Convention date, Sept. 29, 1934. [Class 40 (v)] A multi-range receiver is provided with means interlocked with the wave-range switch for changing the sensitivity and/or the A.V.C. characteristics and/or the fidelity curve in different positions of said switch. A complete receiver having five wavelength ranges is described, Fig. 1 (not shown), the skeleton circuit of which is shown in the Figure, and comprises R.F. amplifier 10, detector-oscillator 11, first and second I.F. amplifiers 12, 13, detector-A.F. amplifier 14, and auxiliary I.F. amplifier 19 feeding A.Y.C. diode 18. The fiveposition wave-changing switches 130, 131 are ganged with switches 85, 68, 135 controlling the sensitivity, A.V.C. characteristic and fidelity curve of the receiver, respectively. Thus, on wavebands B, C, D the switch 85 connects a manually adjusted portion 37 of the self-bias cathode resistance of valves 10, 11 in parallel with a portion 104 of the self-bias resistance of valves 12, 13 while on wavebands X, A the resistance 37 controls the valves 10, 11 only. Two sources of A.V.C. potential are provided namely amplified delayed control bias from the load resistance 62, 63 of the A.V.C. diode 18, and bias from the load resistance 74 of the diode portion of valve 14. The switch 68 connects the grid circuits of valves 11, 12 to the first source on wavebands X, A and to the second source on wavebands B, C, D, while valve 13 is controlled always by the second source and the valve 10 by the first. The input circuits of valves 10, 11, however, are arranged so that the grids are earthed for D.C. potentials when switches 130, 131 are operated to receive waveband D. The fidelity control switch 135 is arranged to have no effect on wavebands X, A but to reduce the low-frequency response of the receiver on wavebands B, C, D by shortcircuiting a portion of a variable resistance in an audio-frequency tone-controlling network. Specification 440,483 is referred to.

Abstract: 1407568 Halogen incandescent lamp PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 25 May 1973 [31 May 1972] 25153/73 Heading H1F A halogen incandescent lamp is made by filling an envelope provided with filament with a a gas mixture comprising an inert gas and a hydrocarbon halide compound, sealing the lamp, cooling the sealed lamp to a temperature below the condensation temperature of the inert gas and then immediately operating the lamp so as to decompose the compound into carbon and a hydrogen halide. In an embodiment, an envelope having a tungsten filament is filled with a mixture of Kr and CH 2 Br 2 , sealed and immersed in liquid nitrogen. The lamp is removed from the liquid nitrogen and a voltage applied across the terminals which is 80% of the operating voltage. The voltage is then increased to 110% of the operating voltage. No deposit of carbon black is observed. The inert gas may also be Xe or Ar. The carbon released by decomposition is said to serve as a getter for unwanted residual gases such as oxygen.

Abstract: 1,184,190. Stamping. KAISER ALUMINUM & CHEMICAL CORP. 27 May, 1968 [17 July, 1967], No. 25285/68. Heading B3Q. [Also in Division F2] In a seamless can forming apparatus having an actuating piston 94 mounted in a closed fluid circuit and reciprocated to and fro by a reciprocating driving member 72 located in the fluid circuit to pass purches 98 attached to each side of the piston 94 through associated dies 250 upon each alternate stroke of the piston 94, lost fluid in a portion of the fluid circuit causing overstroking of a punch 98 is replaced from a control chamber 126, 126<SP>1</SP> to re-establish correct stroking of the piston 94. The driving member 72 includes a shaft 74 connected to a pair of crank arms 76 disposed on driven journals 78. As the shaft 74 is rotated, slides 82 are moved up and down and a yoke 84 is reciprocated to and fro to alternately force fluid against the opposing sides of the piston 94. If the piston 94 overtravels to the left due to fluid leakage from the chamber 90, a switch LS 3  is tripped by a contact X on a right hand punch 98. A solenoid 2 is energized to connect ports A and C through valve 130 so that air from line 135 is caused to move a piston 128 in the chamber 126 to force fluid therefrom, past a valve 124 and into the bottom of chamber 90 to replace the lost fluid. The fluid from the chamber 126 is also caused to flow through line 138, valve 140 and lines 160, 112, 114, 116, 118 into the bearings of the driving member 72, which is continuously lubricated by fluid during operation of the apparatus. At the end of the stroke of the piston 128, a switch LS 2  is opened to de-energize solenoid 2 and return the valve 130 to the neutral position whereupon the piston 128 is retracted and the chamber 126 refilled with fluid. If the piston 94 overtravels to the right, the chamber 92 is replenished with fluid from a control chamber 126<SP>1</SP> in a similar manner. If the movement of a ram 98 on one side of the piston 94 is obstructed, the fluid pressure on the opposite side of the piston 94 is increased and forces open a valve 100 so that the fluid flows through a by-pass 99 and then opens a further valve 100. Circulation of the fluid through the by-pass 99 causes the piston 94 to stop.
