IPC: E04B1/21
Filed: 1942-06-05
Abstract: 559,237. Building frameworks. LONDON FERRO-CONCRETE CO., Ltd., and MUNZ, S. June 5, 1942, No. 7685. [Classes 20 (i), 20 (ii) and 20 (iv)] A rigid framed building structure of metal or ferroconcrete is provided with rigid joints adapted to resist both shear and bending moment at the points of contraflexure of the uprights and the beams. The points of contraflexure in the members being predetermined according to the loading to which each member is submitted. For a concrete structure the columns c are provided with pinned or combined half lap and pin joints 7 formed by pin members 5 entering recesses. 16 in the members and being secured therein by cement. The columns carry cantilever sections e to the ends of which are secured beam sections g by inclined half-lap pinned and bolted joints 9 and the spaced beams g are interconnected by further cantilever members j and beams sections k also joined by rigid joints at the points of controflexure. The column sections may be formed by a projection on one concrete member entering a corresponding recess in the end of the adjacent member and being cemented therein. For a ridged arched member, Fig. 7, comprising uprights 17 and inclined arch members 18 the rigid joints 19 are disposed at the points of contraflexure of the arched member. For metal I-section beam-construction the joints at the points of controflexure are formed by cutting away half of the sections on the abutting ends of the cantilever 21 and frame bar and welding short lengths of angle section bars 24 to each side of each bar at the cut away portion so that the flanges of these bars can overlap and be secured together by bolts. Outside butt straps may also be secured over the joints in the flanges of the bars. The cantilevers 21 are welded end on to the stanchions 20 on each side thereof. Specification 557,588 is referred to.

Abstract: 768,477. Making stranded electric conductors' STANDARD TELEPHONES & CABLES, Ltd. March 18, 1955; No: 7944/55. Class 87(2). In making a stranded electric conductor, the interstices between the individual conductors 1, Fig. 1, of the strand being filled with a longitudinal barrier 2 of thermoplastic material, the conductors are fed, Fig. 2, through a closing die 3 together with thermoplastic filaments 7 which are to form the barrier, and heat is applied to the filaments, to cause them to soften and fill the interstices. The heat may be applied to the closing die or to the conductors before they enter the die. As shown, use is made of an auxiliary die 5 which determines the angle of approach to the closing die. The filaments may be of polythene or a polythene compound. Additional filaments may be applied to fill the outer interstices of the strand.

Title: Amplifier regulation
Inventor: BARBER DONALD ROBERT
IPC: H03G1/00
Filed: 1964-02-26
Abstract: 997,978. Automatic volume control circuits. STANDARD TELEPHONES & CABLES Ltd. Feb. 26, 1964, No. 7967/64. Heading H4R. [Also in Division HI] In an automatic volume control circuit the gain of an amplifier is controlled by an electrolytic variable resistance device. The Figure shows an amplifier 2 whose gain is controlled by the level of a pilot signal which is selected, amplified, and rectified in the pilot selector 4. The resulting D.C. level is compared with a reference level in the comparator circuit comprising transistors 5 and 6 and difference in the levels causes current to flow from the collector of one transistor to the collector of the other transistor through the electrolytic variable resistance device 8. The flow of current in the device 8 causes the plating, or deplating, of a layer of copper on the surface of a carbon substrate 12 from, or to, the copper electrode 11 via the copper sulphate electrolyte, thus reducing, or increasing, the value of the resistance between terminals 13 and 14. The resistance between terminals 13 and 14 is connected, via transformer 9, in the equalizer network 3 across the input to the amplifier 2, and a change in the value of the resistance produces a change in the attenuation of the equalizer network, tending to maintain the level of the pilot signal at the output of the amplifier constant. Relay contacts 15 are provided which are controlled, by means not shown, to open on an abnormally large deviation of the pilot level, such as may be due to a fault in the pilot circuit, so that, for the duration of such a condition no plating or deplating current can flow in the device 8 and the value of resistance 12 is maintained at its last known value.

A travelling gantry 10 is driven along a track 12 by endless chains which engage fixed abutments 20 as described and claimed in the parent Specification, the bottom run of the chain being driven by pairs of sprockets 19. Sprockets 14 are freely rotatable and the sprockets 19 are driven by a shaft 17 through a pair of pinions. The sDrockets 19 may be mounted directly on the drive shaft. Instead of the abutments being engaged by rods which extend between a pair of parallel chains as shown, a single chain may run between adjacent pairs of abutments which are engaged by rods which project at each side of the chain. A guide rail 24 prevents the chains from rising above the abutments.

Abstract: 385,283. Thermal switches. ROZUMEK, E., 1, Am Fenn, Steglitz, Berlin. March 17, 1931, No. 8231. Convention date, March 18, 1930. Void [Published under Sect. 91 of the Acts]. [Class 38 (v).] A thermal switch of the hot wire type comprises a current supply bar 1 which carries a fixed contact 3 and is connected to and insulated from a second current supply bar 2 having a pivot 5 for a lever 6 carrying a contact 4. The lower end of the bar 2 carries a stirrup 9 to which is attached the lower end of a wire expansion winding 8, the upper end of which is attached to two straps 10. The lower ends of the straps 10 carry the lower end of a second winding, the upper end of which is attached by a pin to a stirrup 11 having a screw 12 which engages the contact-lever 6. When the windings expand on heating, their expansions are added and the screw 12 is raised to allow the switch to close under the action of a spring 7. A coiled compression spring surrounds the screw 12 and serves to keep the windings taut after the switch is closed. The screw 12 has a cylindrical end sliding in a hole in the lever 6 to prevent disengagement due to further heating after the switch is closed. In a modification, the two windings are mounted separately on each side of the current supply bars. The switch is mounted in an evacuated container and a flat condenser may be mounted between the current supply bars.
