Title: An improved device for tightening metal bands around boxes, cases and the like
IPC: B65B13/02
Filed: 1920-12-21
Abstract: 155,752. Edler, E. Oct. 7, 1918, [Convention date]. Wire-strainers.-Relates to devices f or tightening metal bands, around boxes and cases before joining their ends. The device comprises a bed-plate u carrying a clamping-device comprising a cam disk f co-operating with a plate b and released by a handle e. A sliding bar g carries a similar clamping-device f<1> and is connected to a lever i by links m, m<1>. On moving the lever i in a clockwise direction, the link m is made to press against a face l of the lever and the bar g is drawn to the left, tightening the band. When the lever is moved in the reverse direction, the backward movement is assisted by the co-operation of a tooth o and notch p. If the first tightening operation is insufficient, the clamping-device f<1> is released, the band being meanwhile held by another clamping-device f<2> on the plate a, and the clamping-device f<1> is then slid back into position for a fresh pull. The bar g may be held in any position against the pull of the band by a cam n.

Title: A process of treating textile fabrics for rendering them less liable to creasing andresistant to crumpling
IPC: D06M15/39
Filed: 1936-12-30
Abstract: Fabrics are rendered crease resisting by first sizing the fabric so that the fibres are individually coated with a film of latex, rubber, rubber derivative, siccative or vulcanized oils and then with synthetic and/or natural resins.  The first treatment is preferably with an aqueous rubber dispersion, which may contain vulcanizing substances and dispersing media; solutions of rubber in solvents such as benzol and toluol may be used.  Vulcanizing may be effected before or after the resin treatment.  In an example, a fabric is impregnated with a 40 per cent solution of latex containing some alkylated naphthalene sulphonic acid as a dispersing agent, dried, treated in a solution containing urea, formaldehyde and lactic acid as catalyst, dried and heated to 150 DEG  C.

Abstract: 1,197,613. Phase shifters. INTERNATIONAL STANDARD ELECTRIC CORP. 4 Aug., 1967 [8 Aug., 1966], No. 35859/67. Heading H1W. [Also in Division H4] In a planar aerial array (see Division H4) with frequency and phase variations to effect pencil beam directional variation in respective co-ordinates, the phase variation is effected by varying the cross-sectional dimension of a waveguide. In an embodiment the beam elevation angle is frequency sensitive, the individual radiators, e.g. 108, Fig. 1, are crossed slots in columns and rows, each column receives excitation from spaced points along a waveguide formed into a " serpentine " (to afford adequate frequency scan sensitivity) and the serpentines are stacked horizontally and fed from successive points along a variable width waveguide phase distributer to effect beam direction variation in azimuth. Each serpentine, e.g. 102, engages by pin and hole with an adjacent one. A projection 117 fits into the cavity 105 of an adjacent section and includes choke slots 118, 119. A serpentine is connected to a point on the phase distributer-top outline is 103-via a coaxial coupler 113. Phase changing. Fig. 2. A member 203 varies the width of waveguide 209. Slots 204, 205, 206 eliminate R.F. leakage. Bars, e.g. 220, 222, move member 203 whilst maintaining its parallelism with waveguide opening 209. Blocks 218, 219 provide for making fine adjustment of waveguide width by set screws not shown. R.F. power input is at 210.

[Also in Group XL (c)] A switching-circuit wherein two capacitors such as C2, C22 and an interposed rectifier D22 form an A.C. path between selected input and output circuits E, S, has the cathode of a threeelectrode gas tube such as Tg22 connected between the input capacitor C22 and the rectifier D22 and one end of a decoupling inductance such as L12 connected between the output capacitor C2 and the rectifier D22. In its broadest form, the required circuit is selected by applying a direct voltage via a load to the anodes of one column and a further direct voltage to the auxiliary electrodes of one row. As described, each rectifier is normally biased off via r22 and is made conductive when its associated gas tube is fired. The auxiliary electrode voltage is then removed to prevent firing of the other tubes in the same row when voltage is applied to their anodes. The anode load R2 is made sufficiently high to prevent the firing of other tubes in the same column when voltage is applied to their auxiliary electrodes. The selected circuit is opened by removal of the anode voltage.

As shown the counterweight 10 is mounted on linkages each comprising a first link 14 pivoted at its lower end at 13 on the platform 8 and at 15 to a second link 16 pivoted at its lower end at 17 to the counterweight 10. The upper end of the link 16 is guided for linear vertical movement by an axle 18 movable between bars 19 on the platform 8. A damper 23 is connected between the counterweight 10 and a rod 22 on the platform 8. The distances A, B, C between the pivot 15 and the pivots 13, 17 and the axle 18 are adjusted to obtain an oscillation period suitable for efficiently damping the counterweight 10.

Title: Insulated pipe and a method for the laying of pipes

Filed: 1971-08-03
Abstract: 1325788 Buried and insulated pipes I QUASSOWSKI-KEMPF 3 Aug 1971 [7 Aug 1970] 36436/71 Heading F2P A pipe is insulated by a covering formed from a plurality of insulating shells which co-operate to completely surround the pipe along substantially its whole length, the shells having at least on the inside a coating of bituminiferous material and a resistance to temperature of above 180‹ C., and an embedding substance covering the pipe along substantially its whole length, the embedding substance containing bitumen and a heat retaining aggregate and filler, the embedding substance having a greater coefficient of thermal conductivity than the shells and being of greater thickness than the shells. A method of laying such a pipe may incorporate the lagging steps before or after the introduction of the pipe into the ground. Thus sections of the pipe may be welded together in a trench before lagging, or lagged sections with free ends may be laid in a trench, the ends welded, and lagging applied to the joint areas. The embedding substance may be contained within a sheet metal case 5. The Shells.-The shells are preferably semicylindrical and include a core having a temperature resistance in excess of 180‹ C. covered with bitumen or asphalt, the covering being preferably between 5 and 15 mm. thick. The shells have a thermal conductivity between 0À04 and 0À07 k.cal./mh.‹C,, and preferably have a density of 300 kg./m<SP>3</SP>. Shell cores may be of pearlite particles or foam glass particles embedded in a binder such as water glass or high temperature bitumen and may be dried at 300‹ C. Alternatively the shells may be of foam glass. The Embedding Material (6).-This may be of bitumen with a filler aggregate of higher thermal conductivity than the shells 4. The filleraggregate may be cork, and the bitumen may incorporate a light asphalt, the mixture being cast at about 200‹ C. The material has a thermal conductivity of approximately 0À1 k cal./mh.‹C. Clamps (not shown) may engage outwardly facing grooves 5<SP>11</SP> in the casing 5 to prevent distortion during casting of material 6. Operation.-When the pipes convey hot fluid the coating of bituminous material on the inside of the shells 4 melts and allows movement of the pipes as they expand. Any voids left between pipe and shells may be filled by more bituminous material flowing in between the joins of the shells. The shells have good enough insulation to prevent the embedding substance 6 from losing its integrity.

The base material is Nb or V, although up to 25 per cent Ta can be incorporated in Nb; the carrier material is normally Cu together with Al, Ga, In, Si, Ge, Au, Pt, Sb, Rh, Zr, Pd, Os, Ru, Co, Tl, Sb, As, Bi, Ir or Sn when Nb is the base, or with Al, Ga, In, Si, Ge, Sb, As, Be or Sn when V is the base; the stabilizing metal is normally pure Cu; the barrier metal is preferably Ta but can also be Nb, and therefore can be the same as the base material. The composites can be in various configurations, Figs. 1-12, (not shown) but generally involve the positioning of multi-core filaments or rods within tubes of the desired materials to form the composites, which are then mechanically worked (e.g. drawn or extruded) to the desired shapes, heat-treated to effect the diffusion, and where necessary, subsequently annealed. In the embodiment of Figs. 9 to 12, one layer of niobium serves as both the base and the barrier; also in the embodiment of Figs. 11 and 12, a reservoir of tin can be included within the copper carrier material.
