Title: Improvements in or relating to indicating instruments
Inventor: TRIGG CECIL TODD
IPC: G01R15/00
Filed: 1962-03-23
Abstract: 970,208. Indicating-apparatus; moving coil instruments. S. SMITH & SONS (ENGLAND) Ltd March 22, 1963 [March 23, 1962], No 11123/62. Headings G1J and G1Q. A pointer 6 is displaced clockwise (looking in direction of arrow II) against the restraint of a ligament 7 and hair spring 9 in accordance with the magnitude of an applied signal and a hairspring 27 applies a clockwise torque to the pointer 6 between a predetermined position '4' and a datum position '0' e.g. 75 degrees apart, the opposing spring restraints being equal and opposite when the pointer 6 is in datum position which may e.g. be arranged where the torque of the springs 7 and 9 are equivalent to 125 degrees deflection. With this arrangement the rate of deflection of the pointer 6 is inversely proportional to the sum of the constants of the three springs 7, 9, 27 over the range 0 to 75 degrees and to the sum of the constants of springs 7, 9 over the range 75 degrees to say 250 degrees, the rate of the latter range being 2<SP>2</SP>/ 3  times the rate of the lower so that the scale is relatively closed over the lower range and open over the upper range. As shown, the pointer 6 is mounted on a spindle 2 and the springs 7, 9 are attached to the ends of a coil 15 secured to the spindle 2 and moving in a magnetic field in accordance with voltage derived from a thermocouple in a jet pipe. The spring 27 acts on a spindle 23 to which is secured an arm 26 with a small magnet 29, 30 at each end. The pointer carries another small magnet 22 and when near either magnet 29 or 30 like poles are adjacent to repel one another. Thus as the pointer 6 moves from position '4' to '0' magnet 22 repels magnet 30 turning arm 26 against the restraint of spring 27. When the pointer moves between position '4' and '7' the arm 26 is held so that eventually the magnet 22 approaches magnet 29 which acts as a magnetic stop as disclosed in Specification 854,228. If magnets 22, 29, 30 are not provided the pointer 6 makes physical contact with arm 26 in the lower range. Specification 718,473 also is referred to.

Title: Improvements in or relating to logical circuits
IPC: H03K19/16
Filed: 1962-03-26
Abstract: 949,274. Diode switching circuits. SIEMENS & HALSKE A.G. March 26, 1962 [March 27, 1961], No. 11383/62. Heading H3P. A logic circuit comprises a number of windings on a magnetic core. In use the core is driven only over the linear portion of its magnetization curve. Input pulses are supplied simultaneously to all the windings, and a scanning pulse is applied to at least one of the windings. An output is or is not obtained from all the windings to which the scanning pulse is not applied in dependence upon the magnitudes and polarities of the pulses in the various windings. In Fig. 2, core M1 has windings I and II having opposite senses. Rectifiers Gx, Gy connect the windings to switches Kx, Ky which apply voltages +U or -U to the rectifiers dependent upon the states (" 0 " or " 1 ") of the input pulses. A scanning pulse i is applied to winding I. If the input signal is " 11 " the switches apply - U to both rectifiers, which are therefore conductive. The scanning pulse in winding I induces a pulse in winding II and an output pulse appears at A. If either of the input pulses is " 0 " there is no output pulse. Fig. 4 shows a circuit which gives an output if the input to winding I is " 1 " when the input to winding II or III is also 1. Two cores may be arranged in parallel, with common scan pulses and a common output, to provide a composite circuit, e.g. Fig. 5 (not shown). To obviate the need for switches K, input may be arranged as Fig. 6, the input pulse being applied to a winding P on an additional core M12. This has the same sense as winding S. Rectifier E2, normally non-conductive, is rendered conductive by a pulse " 1 " in winding P so that a scan pulse on core M1 may provide an output at A.
