Filed: 1927-10-11
Abstract: 279,080. British Thomson-Houston Co., Ltd., (Assignees of Hough, E. L.). Oct. 16, 1926, [Convention date]. Switching supply mains 1, Fig. 1, are interconnected with a DC load circuit 2 through a rectifier 9, and the installation is provided with means to prevent connection unless all the phases of the supply 1 are energized, means to strike the arc of the rectifier and to ensure its maintenance at light loads, and overload and reverse current protective means. If the supply 1 is correctly energized the relay 22 closes, so that upon closure of a switch 21 due for example to a change in the voltage circuit 2, relays 25, 27, 31 and 33 are successively energized, and switches 35 are closed. Motor generator set 39, 15 thereupon operates and energizes a coil 16 to draw an auxiliary anode 13 into contact with the cathode 11 of the rectifier. As soon as these electrodes touch, relay 14 is energized to open the circuit of the coil 16 and allow the anode 13 to be drawn back by a spring to strike the arm, and to energize a time delay relay 41. Movement of contact 42 of relay 41 opens the circuit of time delay relay 34 which circuit was completed when relay 31 was energized. Movement of contacts 42 also completes the circuit for the closing coil 43 of main circuit breaker 5 which thereby connects the rectifier 9 to the supply 1.

Abstract: 644,807. Electric indicating systems. SCOLES, G. J., TODD, K. W., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Oct. 7, 1947, No. 26941. [Class 40 (i)] [Also in Group XL (b)] In apparatus for determining the rotational speed of a member, a rotor, which rotates at a speed proportional to that of the member, controls light passing from a source to a photocell so that the cell is activated at a frequency proportional to the speed of the rotating member. As shown, light from a source 1 passes to a photo-cell 3 by way of a light guide 2 which may be of " Perspex " (Registered Trade Mark). The end of a rotating shaft 5 is cut away so that the light to the photo-cell is periodically interrupted. The shaft may also be arranged as shown in Fig. 1A so that the cell receives a pair of unequal impulses in each cycle enabling the direction of rotation of the shaft to be determined. In a further embodiment the shaft is situated at the far end of the light guide and reflect light back along it to a photocell situated beside the light source. The construction of the shaft end is shown in Fig. 3, surface 12 and 13 being reflecting and again applying different impulses to the photo-cell. The output of the photo-cell is applied to the " Y " plates of a cathode-ray tube, a known circuit arrangement providing a time base on the " X " plates. The auxiliary deflection of the trace appears at one end or the other of the trace depending on the direction of rotation of the shaft. The circuit described is a modification of that described in Specification 644,810, which may be used to measure the output frequency of the light-sensitive device.

Title: Improvements in and relating to the splitting of mica
Inventor: DAVIDSON THOMAS WILLIAM
IPC: C04B14/20
Filed: 1954-09-17
Abstract: Mica is split by introducing a liquid between the laminae thereof and suddenly subjecting the mica to a reduced pressure to cause rapid vaporization of the absorbed liquid.  To introduce the liquid between the laminae the mica may first be heated to remove the water of constitution and then mixed with the cold liquid.  Alternatively the mica may be transferred from a low pressure atmosphere into an atmosphere of higher pressure and, before the gas or vapour between the laminae can assume the higher pressure, immersed in the liquid at that higher pressure.  In an example muscovite mica is heated for 40 minutes at 800 DEG C. to remove the water of constitution and then plunged into cold water which is absorbed between the mica laminae. Water is drained from the mica, and the latter is heated to the boiling point of water in a container connected to a further container by a conduit comprising a closed valve.  The valve is then opened so that some of the mica is drawn into the evacuated chamber where it disintegrates into fine flakes.  Specification 762,192 is referred to.
