Title: Thermal overload electric relay
Inventor: CHAFER HENRY JAMES
IPC: H01H71/18
Filed: 1960-09-13
Abstract: 932,104. Electrically tripped circuit-breakers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 29, 1961 [Sept. 13, 1960], No. 31517/60. Class 38 (5). A thermal O/L relay includes a conducting member 4 which restrains a bimetallic arm 1, pivoted in a notch in an insulating base 2, against the bias of a spring 3. Current passing in the conducting wire 4 between terminals 5 heats the wire which is elongated and allows the arm 1 to move anti-clockwise so that an insulating projection 6 actuates a tripping mechanism. Due to its relationship to the wire 4 the bimetal 1 is heated by radiation, convection and conduction to shorten the effective length of the arm 1 and increase the movement of the projection 6. This allows a greater deflection setting for the tripping action so that the time required for deflection is greater at relatively low currents (Figs. 3 and 4, not shown), and the tripping action due to short pulses of current is avoided.

Title: An improved form of construction for machine parts, and constructional elements, having apertures, drilled holes or the like
IPC: B21D28/24
Filed: 1935-11-14
Abstract: 465,615. Linkwork. RINAGL, F. Nov. 14, 1935, No. 31541. Convention date July 24. [Class 80 (iii)] [Also in Group X] Machine parts and constructional elements, having apertures such as drilled holes which are stressed by outside forces, have further apertures, slots, or inserts of another material on one or both sides of the main hole interrupting the continuity of the material taking the main stresses, and lying in the direction in which the force is applied to the member, the interruptions tapering or diminishing in size in the direction away from the main aperture. The lines of force in the material are thus prevented from crowding together near the main aperture. Holes 5, 6, Fig. 2, are formed on either side of the main hole 2 in a rod 1, the diameter or width of the holes decreasing outwardly from the hole 2. A slot 10, Fig. 5, of semi-oval form is provided adjacent the hole adapted to receive a pin 9, in a link 1. The slot 10 may be formed by drilling two holes at the ends of the slot which is then cut by a saw or burner. The holes may be joined by longitudinal slots, or the auxiliary holes may be replaced by.a longitudinal slot. The holes may be filled with cement, solder, or other material to prevent rusting. A filling which will transmit the strain but not adhere to the walls of the aperture may be employed in a reciprocating thrust rod, or other member for the transmission of alternate tension and compression. The material between the slots 10 and the main aperture may be removed and replaced by a piece of another material. In a further modification, the aperture 2 may be drilled in an oval piece of another material which has been inserted in a hole in the main member.

Title: Improvements relating to high frequency heating processes
IPC: H05B6/50
Filed: 1946-11-27
Abstract: 619,211. Dielectric heating. LUDLOW, J. H., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Nov. 27, 1946, No. 35182. [Class 39 (iii)] A timing device, for use with a dielectric heating process which is followed by a curing period in a press, comprises two valve timing circuits adapted to switch off the dielectric heating at the end of a first predetermined period and simultaneously start the second timing circuit which at the end of a second predetermined period provides a warning signal that the curing period is completed. Closing switch S to complete the circuit to the dielectric heating apparatus H also closes the mechanically coupled switch S, which makes V, conductive, resulting in a fall of anode potential until the anode current is transferred to the screen grid resulting in a heavy current which operates the relay A. This will open the normally closed contacts A; in the heater circuit. At the same time the normally open contacts A2 in the screen grid circuit of V2 will be closed causing V2 to become conductive. A second timing operation similar to the first ensues at the end of which relay B will operate to close the contacts B, and operate an audible or visible signal. The operation of relay B may also be employed to open the press. Specification 602,642, [Group XL (c)], is referred to.

Filed: 1937-11-18
Abstract: 493,176. Hydroplanes. BURTENBACH, H. F. S. VON. Nov. 18, 1937, No. 31758. [Class 113 (ii)] A hydroplane having transversely stepped, gliding surfaces on the bottom of the hull and adapted to be supported in motion by lifting planes disposed under the hull which are inclined in the transverse direction and extend partly above and partly below the water level, are arranged so that the stepped individual gliding surfaces of the hull are spaced as widely as possible in both transverse and longitudinal directions on the craft and are disposed to assist in stabilizing the main lifting planes which are located directly below the spaces of the gliding surfaces. A hydroplane is provided at the bow with gliding surfaces a underneath which is the lifting plane fa, whilst, at the stern, are hull gliding surfaces b<1>, b<2> below which is a lifting plane fb. The hull may have an intermediate plane i beneath a step, and further there may be auxiliary lifting planes g at the bow. In an alternative, the planes fb are placed slightly forward of the stem, and further planes fc co-operate with gliding surfaces e on the craft at the stern. The gliding surfaces of the hull may be keeled or not and are arranged at the forward part with an inclination which is always positive, even when the boat is down at the nose. Supplementary lifting surfaces g and gliding surfaces e may be disposed at the bow. The lifting planes may be disposed directly on the hull, and are preferably set at a transverse angle from 25 to 30, but they may be supported by struts s. Further, these planes may have a re-entrant angle at the centre. In one form, the strut is supported by a frangible pin from a bracket on the hull which yields when the strut meets an obstruction. Preferably, the propellers are disposed below the aft lifting plane behind which may be the rudder. Alternatively, the strut s may be constituted by part of a rudder. In some constructions, the angle of the lifting planes may be adjusted, the planes being pivotally mounted and linked to a member which may be manually operated or automatically operated by hydraulic pressure acting against a spring. Various cross-sections of the lifting surfaces are shown in Figs. 17 to 22.

Abstract: 1,100,357. Analogue-digital converters. INTERNATIONAL STANDARD ELECTRIC CORPORATION. 15 July, 1966 [21 July, 1965], No. 31895/66. Heading G4H. In an analogue to digital multiplex coder (Fig. 3), a plurality of independent analogue signals M1 . . . M(m-1) are simultaneously compared in associated comparators S1 . . . S(m-1) with a reference sawtooth or staircase voltage to enable, when the two inputs to one of the comparators are identical, the associated line of a memory MR1 the columns of the memory being enabled by the binary coded outputs of a counter C3 into which clock pulses are fed as the reference voltage increases in amplitude. Consequently the values of all the input analogue signals are stored in binary coded form in the lines of the memory MR1 when the reference voltage reaches its maximum value. Before the reference voltage starts its next cycle the contents of the memory are transferred column by column into a second memory MR2 from which they read out for transmission during the next cycle. Means for synchronizing the cycles of the reference voltage and the read out from the memories are described.
