Title: Improvements in or relating to devices for simultaneously measuring and checking several quantities, and in particular for simultaneously checking several dimensions
IPC: G05B11/32
Filed: 1954-08-23
Abstract: 764,893. Electric indicating systems. BUISSON, P. Aug. 23, 1954 [Aug. 25, 1953], No. 24507/54. Class 40 (1). [Also in Groups XXXVI and XL (b)] Apparatus for checking that a number of quantities are within prescribed limits comprise means for converting each quantity to a corresponding electric variable and which controls the position of the moving element of a measuring instrument and means for operating a control when any of the moving elements intercepts a light beam passing to a photo-electric cell. As shown, the invention is applied to determining simultaneously that the separate diameters of a shaft mounted in V-blocks 16 is within prescribed limits. The appropriate diameters are gauged by known devices 10, 10<SP>1</SP>, 102 which are each carried on leaf springs so as to bring an anvil 11 into contact with one end of the diameters, members 13 contacting the other. These devices produce an electrical output dependent on the diameter being gauged, part of the tapped output being tapped from a potentiometer 17 and used to position the pointer of meter G. The meter faces are aligned as shown and each has two apertures 41, 4 through which beams of light 5, 5<SP>1</SP> respectively pass to photo-cells 6, 6<SP>1</SP>. The response of each meter to the gauge output is so adjusted by means of the associated potentiometer that the total instrument travel over the prescribed limits is the same. If any valve is outside these limits the pointer cuts off light passing through one of the apertures causing one of cells 6, 61 to operate a warning device. The invention may be applied to checking simultaneously the level temperature and pL value of liquid in a tank. Specification 768,723 is referred to.

Abstract: 671,335. Magnetic-induction accelerators. AKT.-GES. BROWN, BOVERI, & CIE. Sept. 22, 1948 [Sept. 23, 1947], No. 24822/48. Class 39 (i). In an electron accelerator with at least one electron injector, the cathode of the injector has for a short period a voltage applied to it which is derived from a saturated current transformer, the primary winding of which is in the circuit formed by the accelerator winding, the starting instant being adjustable by means of an additional current flowing through the saturated current transformer which is displaced in phase relative to the excitation current of the accelerator, and the impedance of the circuit of the additional current being large. The additional current for adjusting the starting instant of the peaked voltage applied to the electrodes of the injector 6, 7, is supplied by a transformer 9 through a resistor 8 to the winding 4 of the saturated current transformer 3. The magnetizing current in the winding 1 of the accelerator is compensated by condensers 2. The currents in the windings 1 and resistance 8 are displaced in phase by about 90 degrees and give an adjustment in phase of the resultant current. In one modification the accelerator is connected across two terminals and the transformer is supplied from a voltage source displaced by 90 degrees in phase from that across the terminals and has an adjustable winding in series with a choke coil which replaces the adjustable resistance of Fig. 1. The choke coil has an inductance at least five times that of the current transformer and a low capacitance winding with a small number of turns. A capacity may replace the choke coil. In Fig. 3 there are two electron injectors 6, 7 and 6<SP>1</SP>, 7<SP>1</SP> with a phase displacement of 180 degrees introducing beams into the accelerator in opposite directions. Thyratrons 14, 14<SP>1</SP> are controlled by the voltage peaks of transformers 3, 3<SP>1</SP> and connect condensers 2 to oscillation circuits including capacities 16, 161 and inductance 17. The starting instant for the voltage peaks can be adjusted by means of the resistors 8, 81. The additional current may flow in a third winding on the saturated current transformers 3, 31.

Abstract: 764,473. Phase discriminators. GENERAL ELECTRIC CO. Oct. 3, 1952 [Oct. 3, 1951], No. 24842/52. Class 40(5) Phase displaced sinusoidal half waves 49, 50 of opposite polarity are subtracted to give a discriminator characteristic 53 and the latter covering a wide phase range of 3 the order of Œ - #, 4 linearised by potential variable resistors. As shown the phase difference between wave source 10, 11 of fixed and variable phase but equal frequency is derived by first equalising the wave amplitudes in limiters 13, 27, then applying the vector sum of the waves, after each has alterlately in turn been delayed by a phase angle # = n r Œ Á where # < #/2, in delay networks 14, 28, through cathode followers 12, 29 to peak detector valves 22, 36 whose outputs are respectively one particular ordinate of the half waves 49, 50 dependent on the phase of the wave source 11 indicated as abscissae relative to source 10. If the delay angle of the networks 14, 28 is 15 degrees the curves are displaced by 300 degrees and the difference of the peak detector outputs is the discriminator curve 53. The outputs of the limiters 13, 27 are connected through decoupling and alternating resistors 42, 43 direct to the grids of the cathode followers such that the imputs to each grid are across load resistors 17, 32 of valve producing no reflected wave and are of equal ,amplitude. The differential output of the detectors 22, 36, after amplifying at 46, is then passed through a circuit 47 having a non-linear resistor 48' such that the discriminator characteristic is linearised. In a modification the outputs of limiters 13. 27 are applied to opposite ends of a delay # line of angular length less than - con- 2 -nected between the inputs of the cathode followers to produce alternate delays as in Fig. 1, or an equivalent length of transmission line or waveguide might be used. Linearising may also be obtained by a series circuit of back biased rectifiers connected in parallel opposition in place of non-linear resistor 48<SP>1</SP>, or by including non-linear resistors in the inter-valve coupling and at the output of the second valve of two cathode follower stages following the amplifier 46.

Abstract: 599,507. Metal - vapour converters. MASCHINENFABRIK OERLIKON. Sept. 25, 1945, No. 24888. Convention date, Nov. 4, 1944. [Class 39 (i)] The lead-in bolt 3 for an anode in a mercury vapour rectifier in a metal vessel 1 is sealed in the bore of the vessel by means of a resilient packing 15 of insulating material pressed on both sides by insulators 2 and 13 so that the seal is made on the cylindrical surfaces of the bore and of the bolt. The left side of the drawing illustrates the seal to a thick wall tank and the right side the seal to a thin wall tank wherein the bore is extended by the anode case 12 to guide the anode insulator. Grooves 18 on the cylindrical surfaces of bolt and bore improve the sealing and increase the disruptive strength of the lead-in in the axial direction. The packing 15 is of good insulating material such as a rubber composition of high dielectric strength. To increase the surface length of the packing insulator grooves 17 may be provided or the packing can be given any shape to improve the disruptive strength such as a bevelling or step-like arrangement. While the inner insulator 13 is ceramic the outer one 2 may be made of synthetic resin and the insulators are conveniently pressed together by a compression spring and a clamping nut on the lead-in bolt or by flanges or the like.
