Abstract: 765,986. Knockdown boxes. TRIGGS, W. W., (Conrow, R. S.) March 7, 1955, No. 6640/55. Class 18. [Also in Groups XXV and XXX] A knockdown box has its sides hinged either removably or permanently to the base, and in addition to the hinging means, interengaging male and female elements on both the side and base adjacent edges, the elements being formed by castellations. The side and top edges of the sides have similar elements. The hinging means may consist of modified piano hinges, strips of flexible metal secured to the base and sides, rods passing through aligned staples in the adjacent base and side edges, staples driven with one limb in a side and the other in the base, or plates such as 41, 42 with interengaging curled edges 43, 44, Fig. 14. A rod may pass through the edges 43, 44 to act as a hinge pin. The sides are clipped at their adjacent edges by angle strips 33 having flanges 34 engaging grooves 35 in the sides, Fig. 4. A lid 36, Fig. 5, may be held by similar strips 37 or a continuous strip mitred at the bends may be used. Alternatively, the lid may be hinged on one side and have a catch formed of a curled metal strip engaging a similar strip on a side wall, after the fashion of the elements 43, 44. A combination of a hinge with strips 37 and a catch may be used. The end walls may be extended downwardly to provide space for the tines of a lift truck. The box may be rendered siftproof or waterproof by strips of rubber &c. of circular section held in grooves in the abutting edges of the walls or by rubber strips 53 secured to the projecting castellations 17 along the inner edges of some of the walls, the parts joining the castellations being pressed between them by castellations of the adjacent walls, Fig. 15 (not shown). Parts for boxes may be manufactured by cutting rectangular zig-zag patterns three quarters way through the thickness of a sheet of hardboard, securing hinge members over the cuts and trimming away the remaining quarter by passing the sheet over a circular saw, thus separating the various panels.

Title: Improvements in methods of etching bodies
Inventor: FLINN IAN
IPC: C25F7/00
Filed: 1959-02-26
Abstract: 919,158. Etching by electrolysis. MULLARD Ltd. Feb. 26, 1959, No. 6711/59. Class 41. [Also in Group XIX] A method of etching the surface of a body 3, e.g. a germanium or silicon semiconductor, and simultaneously measuring the reduction in thickness of the body 3 comprises directing etchant, e.g. an aqueous solution of an electrolyte, under pressure from a jet 1 on to the body 3, the jet 1 being close to the body 3, indicating, as the body is etched, the reduction in pressure required to force the solution through the gap between the jet 1 and the body 3, e.g. by a water manometer 10, and deriving from such indication the reduction in thickress of the body 3. The body 3 may be connected as the anode and a platinum foil cathode 11 wrapped round the jet 1. Compressed air forces the electrolyte 6 out of a container 5 for delivery through a capillary at 9 to the jet 1. The body 3 may be attached to a micrometer slide and moved discontinuously, if desired automatically, towards the jet 1, to increase the pressure reading at 10 to a predetermined value, the degree of movement measuring the reduction in body thickness, or the manometer 10 may be calibrated and the body 3 kept stationary. The electrolyte may be sodium hydroxide or ammonium chloride, and if N-type germanium is being etched, the body surface should be illuminated, e.g. by directing light transversely of the jet 1, which is of glass, and providing a reflecting surface at 45 degrees to the jet axis in the walls of the jet, so that light passes along the jet 1. A photo-cell may be employed with the manometer 10 to indicate the pressure, or a differential capacitance gauge may be used. Two examples of etching P-type germanium are described, one employing NaOH, the other NH 4 CL. In each case current density is 250 mA/cm.<SP>2</SP>, etchant flow rate 4 c.cs./min., and pressure 10 cms. of water.

Title: Improvements relating to magnetic storage core arrangements
Inventor: WARMAN BLOOMFIELD JAMES
IPC: G11C11/06
Filed: 1958-03-06
Abstract: 863,654. Circuits employing bi-stable magnetic elements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 27, 1959 [March 6, 1958], No. 7301/58. Class 40 (9). In a trigger unit in which two storage cores A, B are linked by cross-connected windings A2, B2 so that a set condition established in core A by a signal in a winding A3 is transferred between the two cores by the alternate application of resetting pulses P1 and P2 to windings A1 and B1 respectively, the cross-connected windings are arranged in series with a winding X1 on a further core X which is subjected to both P1 and P2 resetting pulses in respective windings X2 and X3. Output pulses are developed in a winding B3 until such time as a resetting signal is applied to winding A3, whereupon both cores are brought to the same reset condition. The provision of core X is for suppressing the transfer of small spurious pulses between the two cores when both are in the reset condition, since these pulses will eventualy cause a triggering action to build up. Likewise the core suppresses spurious pulses which will eventually inhibit operation when the trigger action is proceeding. Constructional details are shown in Fig. 4 in which the two cores A and B are constituted by holes in a ferrite block A and B, while the further core is formed by holes in a ferrite block X.

Title: Improvements in and relating to the starting of electric motors
IPC: H02P1/34
Filed: 1924-03-22
Abstract: 235,936. British Thomson-Houston Co., Ltd., and Watson, G. O. March 22, 1924. Controllers, with auxiliary switches and no-volt release; sliders.-A starter 4 of a motor, such as an alternating current motor 1 supplied from mains 2 through a circuit breaker 3, has an electrical interlock 8 which is independent of the starter, and which has to be kept closed during the starting operation. The circuit breaker is held closed by a low-voltage release coil 10, the circuit of which is completed through an interlock 6 when the starter 4 is in its initial position. Closure of the circuit breaker causes the closure of an associated switch 5, so that the circuit of the coil 10 can be maintained during advance of the starter, provided that the interlock 8 is kept closed by the operator. In its final position. the starter 4 closes an interlock 7, so that the operator can then release the interlock 8. Should the circuit breaker open, either due to failure of voltage across the mains, or of the operator to keep the interlock 8 closed while the starter is between its end position, it is necessary to return the starter to its initial position before the circuit breaker can be closed again. The starter may be arranged to close the interlock 8 mechanically in its final position and so obviate the use of the interlock 7.
