Title: Electric measuring and indicating systems
IPC: G01S3/62
Filed: 1945-07-27
Abstract: 596,492. Electric indicating systems. STANDARD TELEPHONES & CABLES, Ltd. (International Standard Electric Corporation). July 27, 1945, No. 19334. [Class 40 (i)] In a system for measuring the change in position of a movable member, a phase-shifter connected to the latter alters the relative phase of two sets of oscillations or pulses, or of a pulse train relative to an oscillation train proportionately to a displacement of the member. In one embodiment, Fig. 1, the movable support 10, carrying antenna 12, the azimuthal position of which is to be indicated at a remote point, is connected to variable condenser 14 of phaseshifter 15. The output of an oscillator 20 is applied to resistor 18 and from outlet terminal 21 the unchanged oscillations are passed to a pulse generator 25, of a known type, and from there to multivibrator 42 and sweep generator 40 to produce sweep line A-B in C.R.T. 45, the multivibrator 42 controlling the beam intensity by electrode 44. To increase the scale of the trace line, a harmonic generator may be introduced prior to the pulse generator. From a second output terminal 22 the oscillations, after passing through phase-shifter 15 are applied to pulse generator 24, and then to deflection plates 46, 47 to produce a break 48 in the trace which appears at a distance along the sweep line A-B corresponding to the displacement of member 10. In a second embodiment, Fig. 4 (not shown), the two trains of pulses are applied to a multivibrator of known form, the output of which is a function of the relative displacement of the pulse trains and is registered on a direct reading meter. In a third embodiment, Fig. 6, the movable member 10 is coupled to the variable inductance 61 of the phase-shifter 15a. A circular sweep line 65 is produced in C.R.T. 66 by valves 67, 68 which are controlled from harmonic generator 88 through phase-splitting circuits 71, 72. The output from pulse generator 24 is taken to the grids of valves 67, 68 and the position of member 10 is indicated by the displacement of the break 85 from a reference point. Specifications 553,286 and 579,671, [Group XL], are referred to.

Abstract: 1533792 Camera shutter SEIKO KOKI KK 13 May 1976 [14 May 1975 (2)] 19777/76 Heading G2A A shutter having opening blades 3 and closing blades 6 has a member 9 which, upon closing movement of the closing blades 6, moves the opening blades 3 back towards the closed position so  that the exposure aperture 1a is at least partially covered thereby. As shown, the shutter has four opening blades 3 and five closing blades 6. By providing a large number of closing blades 6, the space required adjacent the view-finder a to accommodate them can be reduced. However their light excluding property is also reduced and it is for this reason that the return movement of the opening blades 3 is effected. To make an exposure, arms 4 and 5 are rotated clockwise to move the opening blades 3 clear of the aperture 1a, then arms 7 and 8 are moved clockwise to move the closing blades 6 into position over the aperture. As the closing blades 6 complete their movement, a projection 8h on arm 8 shifts a hook 10 to release a drive member 9 which is moved upwards by a spring 9f. Arms 9c and 9d engage pins 4g and 7g on arms 7 and 8 and thereby return all the blades 3 and 6 to their original positions. In Fig. 6 (not shown) arm 7 releases the hook; in Fig. 7 (not shown) the hook is released by the return of a reflex mirror; in Fig. 8 (not shown) the shutter has two opening and two closing blades; in Figs. 9, 12 (not shown) a pin (12) limits the movement of member 9 to reduce the size of the shutter, the return movement of the blades being only partial in this case; and in Figs. 10, 11 (not shown) only the opening blades 3 are returned by member 9.

Filed: 1925-08-13
Abstract: 258,059. English Electric Co., Ltd., (Bremner, F. D. H.). Aug. 13, 1925. Fusible cut-outs.-The arc formed upon the blowing of a fuse 7 is deflected by horns 1, 2 on to two electrodes 8, 9 that pass the arc current through an auxiliary fuse or switch which is then ruptured or opened to extinguish the arc. The electrodes are separated by a projecting block 10 of soapstone or other insulating material, and are connected to the terminals 28, 29, Fig 2, of an auxiliary switch or fuse. The current is thus led through a coil 17 and switch contacts 12, 13. The coil 17 attracts an armature 22 that, after a short movement, moves the switch arm 24 and breaks the circuit, the arc which strikes on to horns 14, 15 being extinguished with the aid of the magnetic field of the coil 17. The blow-out coil may be continuously energized, and the switch opened by a separate coil 30, Fig. 3, into which is drawn a plunger 34 that strikes the arm 24. The switch may be opened by the movement in the field of the coil 17 of a conductor carrying the current to the switch. A single auxiliary switch or fuse may be connected to a number of main fuses. Specification 241,356, [Class 38 (v), Electric switches &c.], is referred to.
