Abstract: 1,195,818. Phase sensitive detectors. BOFORS A.B. 18 March, 1969 [25 March, 1968], No. 14217/69. Heading H3A. A phase-sensitive detector for a chopper-type amplifier A comprises a four-terminal network having: a first shunt path including a switch Q1, actuated at the chopping frequency; a series path including a rectifier D12; and a second shunt path including a capacitor C 11 which is charged through the rectifier D12. If the amplifier output across R1 is positive during the time that Q1 is nonconducting, then D12 conducts to produce a positive output at B. A second similar network Q2, D22, C21 is connected in parallel with the first, in which the switch Q2 is operated in antiphase with Q1 so that, if the output across R1 is positive during the other half cycle of the switching signal, a positive output is produced at D. The switches Q1, Q2 have reverse voltage protection diodes D11 D12.

Title: Improvements in or relating to resistance welding
Inventor: WIRTA ELMER RAYMOND
IPC: B23K11/00
Filed: 1956-05-10
Abstract: 803,736. Making composite metal sheets; welding by pressure; brazing. FAIRCHILD ENGINE & AIRPLANE CORPORATION. May 10, 1956, No. 14602/56. Classes 83 (2) and 83 (4). In resistance welding the edges of a honeycomb core formed of thin metal strip to the face of a thicker metal sheet, a bonding material is disposed between the core and the face of the sheet and at least part of the material is caused to adhere to the core and the sheet by the heat of the weld or upon subsequent cooling, to reinforce the weld and form a connection between the core and sheet where the weld is discontinuous. In one embodiment, a fusible ceramic frit melting at a temperature below the' welding temperature or a thermo-setting initially liquid synthetic resin, e.g. polysiloxane, is applied at 16 by coating or dipping to the edges of a core 10 formed of stainless steel, e.g. 18-8 strips 11 welded at their contact points 12. Two stainless steel, e.g. 18-8 skins 14, 15 are then welded on the sides of the core by roller electrodes 17, 18 to form a honeycomb sandwich, the welding heat melting, at least locally, the ceramic material or partially polymerizing the synthetic resin. In a modification, a woven wire cloth 22 formed of brazing alloy, e.g. a nickel or silver alloy, is placed between each skin 14, 15 and the core 10 to be melted and connect the core edges and skins. The brazing alloy may be applied as a foil or as a suspension of particles in a vehicle. The work may be further heated in an oven after welding to complete the melting of the ceramic frit or the brazing alloy or to complete the polymerization of the resin. The method may be used when a metal wire web or cloth is disposed between the skins and core. The strips forming the core may be coated with a highly conductive metal, e.g. copper, silver, gold or aluminium, as described in Specification 792,165, and closely spaced points of contact between the core and skins as described in Specification 803,735 may be employed.

[Classes 20 (i) and 20 (iv).] A pre-cast, reinforced concrete girder a of tubular or trough shape is provided with a number of reinforcing bars l of different lengths and having diagonally bent parts L<1>, the arrangement being such that the inclined parts l<1> of the longer bars take up shear stresses adjacent the supports when the maximum span is used, whilst the inclined parts of the shorter bars take up these stresses when the girder is shortened to suit a shorter span. If desired, two bars l may be disposed at each side in the lower part of each girder, as shown in Fig. 2, and the inclined ends l<1> may terminate in hooks k, Fig. 1. The hooks k of the longer bars project beyond the ends of the girder. In addition to the bars l, the girder may be reinforced by a longitudinal bar d disposed in each corner of the girder with or without an additional longitudinal bar in each of the upper corners. The lower bars d may be provided with hook-shaped ends k<1>projecting from the girder, and the upper bars may have bent ends k<2>, as shown in Fig. 1. The bars d, l are interconnected at intervals by an open rectangular framework comprising vertical and horizontal wires e, f. U-shaped bars m may also be disposed transversely of the girder at intervals, as shown in Fig. 2. In constructing a bridge, the girders are placed side by side with the ribs b on the side faces in contact so as to leave spaces o for the reception of concrete, as shown in Fig. 5. The projecting ends of the bars l are embedded in a cast-in-situ concrete enclosure x disposed along the ends of the girders, rods w being threaded through the hooked or bent ends k<1>, k<2> of the bars, as shown in Fig. 6. The end girders q are provided with transverse channels, each adapted to receive an "extension s of a rail pillar t. A curb u of concrete is cast over each end girder q. In a modification, the upper side of the girder is omitted to provide a troughshaped girder which may be employed for carrying mains, pipes, &c. When the girder is shortened for use with a shorter span, the ends of the inclined parts l<1> of the shorter bars l may project beyond the ends of the girders.

Abstract: 415,224. Preparation of cellulose pulp &c. POMILIO, U., 40, Calle Central, 3ero Piso, Santiago de Chile. May 22, 1933, No. 14800. Convention date, June 10, 1932. Drawings to Specification. [Class 96.] Cellulose, half stuff &c. is obtained by continuous treatment of vegetable material descending by gravity in a tower, with alkaline lye and with steam, and subsequently with chlorine admitted at about one-third from the top of a second tower through which the material also passes by gravity, the steam and chlorine rising through the material in the upper portions of the respective towers. The material is supplied finely minced to the first tower, the rate of supply of reagents to and of discharge of material from the tower being controlled. The material is then collected, soaked with lye, washed and conveyed to a distributer at the top of the second tower, excess lye being returned to the top of the first. The upper layers of material are open and allow gas &c. freely to pass through whilst the lower layers, being compacted by the pressure are almost impermeable. The towers may be rectangular or elliptical and the first tower may be directly over the second. A continuous supply of lye and chlorine may be obtained electrolytically. A refrigerating mixture may be introduced into the chlorinating tower.

Title: Improvements in apparatus for use in making gold sealed joints
IPC: B23K3/08
Filed: 1944-08-02
Abstract: 592,040. Soldering. M-O VALVE CO., Ltd., and SOWTER, A. B. Aug. 2, 1944, No. 14801. [Class 83 (iv)] In joining to opposite sides of a metal body two supplementary elements by means of gold seals which are coaxial and of different diameters, the parts are held by a clamp spanning the three elements with one end reacting only on the arc of the supplementary elements associated with the larger seal while the other end of the clamp reacts both on the other supplementary element and also through the agency of an irreversible adjusting member on the body element. A single heat treatment may thus be used to unite two joints by gold seals of different diameters which require different clamping pressures. The irreversible member may be a nut or a wedge. The jig includes an elongated rectangular block 1 with a cavity 2 to accommodate a hollow copper body 3 to which supplementary copper elements 5, 6 are tu be soldered by gold wire rings 7, 8 in one operation, the element 6 consisting of a washer fused to the open end of a tubular glass envelope 17 and being passed through an aperture 4 in the base of the block. The block is provided with two pairs of screw studs 9, 10. carrying bridge-pieces 11, 12, provided with tapered bores 13, 14 engaging the heads of plungers 15, 16 shaped to fit the elements 5, 6. The plunger 16 is screw-threaded at 19 to receive a knurled nut 21. In assembling the parts, the bridge 11 is first lightly loaded by tightening the knurled nuts 22 so that the element 5 is forced gently into the body and held against the bottom of the cavity 4. The bridge 12 is then fully loaded by tightening the hexagon nuts 23 on the studs 10 to clamp home the copper washer 6. The rings being compressed by equal loads, the resulting movement of the body 3 and block 1 raises the body clear of the bottom of the cavity, the body being thus unconstrained by the block during final tightening of the clamp so that the elements are free to take a proper bearing in the bottoms of the sockets. To reduce the specific loading on the smaller gold seal, the knurled nut 21 on the plunger 16 is then screwed into engagement with the imderface of the body 3 so that part of the damping load is transferred from the smaller gold seal and taken directly by the body. The Provisional Specification refers to Specification 586,325.
