[Also in Division H1] A voltage supply system for a plurality of electrical module assemblies, Fig. 1, each having terminals arranged in a row adjacent one edge of a module support board 18, comprises a connector panel 15 consisting of at least two mutually insulated conductive sheets which, in operation, carry different voltages, and a plurality of edge-connectors 19, supported by the panel 15, which receive the said edges of the boards 18, the edge-connectors 19 including contacts which engage terminals on the boards 18 and also pass through apertures in panel 15, connecting means being provided for selectively connecting said contacts to selected sheets of panel 15. Two such arrangements, 12, 14, are shown in Fig. 1, hingedly mounted back to back by flexible bus-bars 22 on a frame 13 in a cabinet 16. Fans 20 provide forced-air cooling, and cabinet doors 16a are inwardly contoured so that, when closed, they exert a retaining pressure on boards 18. Each edge connector 19, Fig. 4, comprises end sections 27, 29, and a plurality of intermediate sections 26a of plastics material, the end sections having grooved portions 40 which receive and support boards 18. Each connector section 26a, 27, 29 has a plurality of pairs of tapered tubular projections 28 which pass through apertures in panel 15, the latter comprising a first voltage sheet 15a of Cu or Al insulated on both surfaces, and a second, thicker, uninsulated Al voltage sheet 15b . Each connector section 26a houses a plurality of contact terminals 17 each comprising a bowed contact portion 17b, and a terminal portion 17d of square section which passes through a projection 28 and extends beyond the panel 15 to receive a wrapped wire connection. A similar contact terminal 17 is provided in the first position in connector end section 27, and is connected to voltage sheet 15a by a metal bushing 38 having a serrated edge which pierces the insulation on sheet 15a and makes connection therewith. Alternatively, a strip from sheet 15a may be bent parallel to terminal portion 17d and be connected thereto by wire wrapping. A further contact terminal 17 is located in the first position in connector end section 29; here the projection 28 is replaced by a metal bushing 41 which connects this terminal 17 to voltage sheet 15b. Further voltage levels are provided on conductive strips 21 which pass through slots 31, 32 in connector end sections 27, 29, and which comprise integral contacts 33. Voltages to sheets 15a, 15b are supplied by a fixed laminated bus-bar 26, Figs. 1, 2, and a plurality of flexible bus-bars 22 each comprising mutually insulated laminated sheets of beryllium copper, and being clamped to sheets 15a. 15b by plates (not shown) and bolts. Conductive strips 21 are welded between pins 21a which are held insulatedly in the sheet 15b, and which are connected to a voltage source via conductors 24.

Title: Improvements in or relating to overload device for metal working press
IPC: B30B15/28
Filed: 1950-08-24
Abstract: 671,894. Metal-working presses. CLEARING MACHINE CORPORATION. Aug. 24, 1950 [April 7, 1950], No. 20951/50. Class 83 (iv). In a mechanicallyoperated metal working press, more particularly for sheet-metal, comprising a bed 1 and crown 2 spaced apart by uprights 3 and pulled together by tie-rods 10 at each corner of the frame, each tie-rod is associated with a prestressing and overloadpreventing device consisting of a lever 16 pivotally mounted at one end on the press frame and pivotally connected adjacent that end to one end of the tie-rod and a yieldable means to exert a force on the other end of the lever so as to place the tie-rod under stress and to yield at a predetermined pressure. In one form, Figs. 3 and 4, the lower end of each tie-rod 10 is screwed into a coupling 14 through which passes a horizontal pintle 15, the ends of which are received eccentrically in a housing integral with the lever 16 and having circular ends 17, 18 mounted in bearings 23, 24 in brackets 25 bolted to the bed 1. The arrangement is such that the lever 16 pivots about a point 21 while the tie-rod 10 acts on the lever at a point 22. At its other end the lever is coupled to the rod 30 of a piston 31 in a cylinder 32 which may be supplied with pressure-fluid at 34 so as to force down the piston and so prestress the rod 10. If, during the operation of the press, an overload occurs, the piston 31 will be forced up against the pressure of the fluid and a predetermined overload will cause a cam 41 on the piston-rod to actuate a switch 38 to stop the press. Pressure could be applied to the lever by a spring or a weight instead of by pressure-fluid. In a modification, the device is mounted in the crown of the press and is coupled to the upper end of the tie-rod. In another form, Fig. 5, levers 42 are pivoted at 44 to brackets 45 secured to the frame and are coupled to the tie-rods at 15 and to the pressure cylinders at 46.

Title: Process for the manufacture of resinous products of condensation from phenol and formaldehyde
IPC: C08G8/28
Filed: 1921-08-08
Abstract: The elasticity of the resinous condensation products prepared by the process described in Specification 159,494 is increased by adding a mixture of amyl alcohol and glycerine, amyl alcohol and camphor oil, or amyl alcohol, glycerine and camphor oil, boiling off the water, and hardening by heating at 90-100 DEG  C., under atmospheric pressure.  The products resemble amber, or, if a great excess of formaldehyde is used in the condensation, are ivory-like; in the latter case an addition of glacial acetic acid after boiling off the water is desirable.

Abstract: 621,694. Frequency modulation; automatic tuning correction. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and EASTER, B. July 12, 1946, No. 20973. [Class 40 (v)] A frequency discriminator for frequency modulation receivers or automatic frequency control comprises a pair of rectifiers D1, D2 with associated load impedances R1, R2 arranged so that the rectifier outputs are in mutual opposition, a divided input circuit L2, C2 connected or coupled between the rectifier circuits broadly resonant at the datum frequency, a piezo-electric crystal PC associated with one rectifier circuit and having its selfcapacitance balanced by a capacitor CN associated with the other rectifier and a reactance resonating with the crystal at the datum frequency and inserted in a common part of the rectifier circuit. The current through the series resonant crystal and reactance combination produces across the reactance the quadrature voltage required for the discriminator to operate. The reactance is preferably a condenser in which case the load resistors are connected to the input circuit side of the condenser to preserve the D.C. path (Fig. 2, not shown).
