Title: Improvements in fabricated girders and trusses
IPC: E04C3/04
Filed: 1949-03-31
Abstract: 659,285. Making girders. KELLER, J. S. March 31, 1949, No. 8813. Convention date, April 2, 1948. [Class 83 (ii)] [Also in Group X] A girder comprises upper and lower T-section chord members 1, Fig. 1 (this Figure shows only part of the upper part), joined by a web of metal members 2 arranged in zig-zag pattern and having divided ends 3 attached to both sides of the chords by a single resistance welding operation. The web members may be of V- or H-section or tubular, with the ends of the web cut away, or of two separate strips having central beads. A number of parallel girders may be connected by further girders 5 welded at right angles which are made less deep so as to fit between the chords of the first girders when they are welded in position. The members 2 are arranged so as to locate the chords 5 of these girders. Some of the joints may be riveted and the girders may be rust-proofed with synthetic resin lacquer by dipping after welding.

Title: Improvements in telemetering and like signalling systems
Inventor: STONOR CHARLES RICHARD PAUL
IPC: G08B26/00
Filed: 1961-03-10
Abstract: 1,001,083. Electric selective signalling. SOUND DIFFUSION (SALES) Ltd. May 24, 1962 [March 10, 1961], No. 8838/61. Heading G4H. A D.C. signalling system comprises a plurality of sets of relay and rectifier equipment interconnected by a single multi-core cable to a central station so that the station can examine the condition of each set in turn. In the apparatus shown the central station has a uniselector switch SS which is stepped through its contacts 1-25 in sequence by an electromagnet SSM operated by a relay P which continually alternates with a relay PR. When the switch is in position 2 a positive voltage is applied through a coil a, b of a relay S1 to core 1 of the cable, which cable interconnects twentyfour sets of equipment LA-LX at different locations in a coal mine. The current produced passes through a rectifier D1 and through a relay LA to return along core 3 of the cable to the centre tap of a battery, not shown. In accordance with whether a switch X1 is open or closed the current passes through or by-passes a high resistance coil H of the relay LA. If the switch is closed the current is sufficient to actuate the relay S1 and give an indication on a control board at the central station. The current through a coil L of the relay LA is sufficient in either case to close a contact LA1. After it has closed the switch SS is stepped on to the next contact 3 connecting a negative supply through a coil ab of a relay S2 to the core 1; this cannot pass the rectifier D1 but passes the contact LA1, a rectifier D4 and a relay LB to reach the core 3. The relay S2 similarly indicates whether the switch X2 is closed and closes a contact LB1. As the positive supply to the relay LA has been cut off the contact LA1 is opened but this does not happen until contact LB 1 is closed as relay LA is damped by a rectifier D3. Next, the switch SS is stepped on to its contact 4 so that the third switch X3 (not shown) can be monitored by a positive pulse in the core 1. In this manner alternate positive and negative pulses applied to the core 1 operate each of the relays LA, LB &c. in turn and relays S1-S24 indicate which of the switches X1- X24 are closed. As the line is of high capacitance and resistance, three contacts A3, T1, P6 are closed sequentially between the steps of the switch SS to first apply a negative supply to the core 1 and then to earth it; this prevents charges in the line from falsely operating the relays S1-S24.

Abstract: 682,414. Foaming slag. HUETTENWERK RHEINHAUSEN AKT.-GES. April 12, 1950 [Feb. 6, 1950], No. 8960/50. Class 22. Molten masses, e.g. blast furnace slags, are poured onto a foaming bed 3, a foaming agent is introduced through apertures 13 into the masses, and after foaming has been completed the foaming agent is withdrawn through the apertures 13. In operation, molten slag is poured from a tippable ladle 8 into the bed 3. Water from pipes 22,25 prevents the slag adhering to the oblique walls 11, 12. Entry and removal of the foaming agent e.g. water is controlled by a three way cock 15 (Fig. 3) which affects pipes 4, 14, and 21. A leader 19 into which all the pipes 14 lead is also connected to the pipe 21, through a stop valve 20. The prepared foamed slag is removed by tilting the mechanism about an axis 2. In scavenging the mechanism the cock 15 is set appropriately and valve 20 opened so that water passes pipes 4, 14, 19 into 21. In modifications, the cock 15 can be replaced by two T-piece members; the apertures can be supplied with water individually and / or in succession ; several mechanisms can be used in line and fed by a single ladle, the pipes 14 may be replaced by a false bottom (see Fig. 5, not shown) and the bed 3 may be made integral with or detachably connected with the rest of the mechanism. A screw 6 allows slight adjustment of the mechanism. The pressure of the foaming agent at the nozzles may be adjusted by varying the effective cross section of the pipe 4 by suitable movement of the cock 15.

Title: Improvements in or relating to casting machines
Inventor: DAVIS RALPH PERCY
IPC: B22C25/00
Filed: 1955-03-30
Abstract: 762,063. Casting-machines. WALWORTH CO. March 30, 1955 [Aug.. 17, 1954], No. 9309/55. Class 83 (1). [Also in Group XXX] A casting-machine comprises a number of casting-boxes 14 on a carrier 10 moved along a predetermined path, and means for loading refractory material into the boxes around shelltype moulds therein. Shot-carrying hoppers 18 are supported on a shaft 20. The boxes are each supported from a monorail 28 by rollers 32 carrying brackets 30 attached to an inverted U- frame 40, 42, 44. The frame carries a centre-pin 46 which is engaged by forked arms 50 at the shot-loading section so that a hopper 18 is carried round with the box. The brackets 30 are linked together by a chain 26 which meshes with a wheel 25 at the loading section. At a mould-loading section, a complete shell-mould is placed in each box. As the box passes into the shot-loading section a lever 112 on the frame 42 engages a switch to open a gate 87 and allow the associated hopper 18 to be filled from a conduit 85. The hopper is then lowered to dispose twin spouts 58 on both sides of the mould by actuation of a valve 124 by a cam 86 causing a piston 76 to raise a counterweight 74. As the hopper descends, a fluid-pressure device 56 is actuated to open a gate 54. The box 14 is then filled with shot until the spouts choke. The gate 54 is closed, the counterweight 74 lowered and the box proceeds to the pouring section. An operator stands on a band 16, which travels with the conveyer, and fills the moulds with molten metal. These then pass to a cooling- section and finally to a dumping-section. Here, an abutment 108 engages the lever 112 to release latching-mechanism 96, 102 to allow the box to swing about trunnions 88 to dump its contents into a hopper 116 and then to return to its initial position. The dumping hopper 116 contains a shake-out grate 114, which is rocked to allow shot to fall into the hopper 116 and thence to a container 118 for re-transmission elsewhere, and which is periodically rocked with a greater amplitude to discharge the mould and casting. If the metal-pouring operator cannot fill a mould in time, he moves the lever 112 to an inoperative position to prevent the dumping operation. When the unfilled mould reaches the loading section the lever 112 does not operate the switch to open the gate 87 and the associated hopper remains unfilled. The piston 76 is then unable to overcome the counterweight and the hopper is not lowered.

Filed: 1953-04-07
Abstract: Aromatic vinyl compounds, e.g. styrene, a -methyl styrene, divinyl benzene, vinyl anisole, vinyl naphthalene, vinyl carbazole or mixtures thereof, are copolymerized with acenaphthene or its nuclear substitution products, e.g. 3-methyl, 3,6-dimethyl, 1-ethyl, 5-isobutyl, 4-chloro, 5-chloro, 1,2-dichloro, 5-bromo-acenaphthene or mixtures thereof in the presence of an anhydrous acid-reacting polymerization catalyst, for example aluminium, stannic, zinc, and ferric chlorides, boron trifluoride, titanium tetrachlorides and complexes such as boron trifluorides, acetic and phosphoric acid, and chloracetato, lactato, oleato, and benzatofluoboric acids.  The reaction may take place in solution in, for example, carbon tetrachloride, benzene, toluene, xylene, solvent naphtha, or mixtures such as toluene and/or xylenes with ethyl acetate, butyl acetate, carbon tetrachloride or cyclohexanone or in an aqueous emulsion containing a catalyst and stabilizer, e.g. sodium lauryl sulphate, ammonium abietate, or a soap.  The catalyst is precipitated by the addition of oxides, hydroxides or carbonates of alkaline metals or earth metals and filtered off, the mixture is then distilled to remove the solvents.  Drying oils such as linseed oil may be present during the polymerization.  The products, which are soluble in organic esters, chloroform, carbontetrachloride and acetone may be used as softening agents or in lacquers, and may be modified by condensation, e.g. with formaldehyde.  Specification 680,441 is referred to.

Class 39 (3) High frequency dielectric heating apparatus comprises two electrodes 10 and 11 ... 18 between which the field is to be applied, one at least of the electrodes being divided into a multiplicity of mutually insulated areas 11 ... 18, and means, e.g. a switch 20, 21, being provided for feeding the areas selectively and in succession with high frequency electric current. When very high frequencies, e.g. 10 megacycles, are employed, a capacitance type switch may replace the switch 20, 21. The use of a plurality of electrode strips 11 ... 18 decreases the capacitance of the apparatus at any instant in use, and hence increases the voltage and so shortens the heating period disproportionately. The Provisional Specification describes also the use of induction coils for supplying current to the strips 11 ... 18, and states that one electrode may be a sheet and the other a movable or stationary roller.

Abstract: 824,988. Spring power-storing apparatus. TENSATOR Ltd. March 21, 1958 [March 22, 1957], No. 9421/57. Class 10. A spring motor comprises a rigidly held drum 13, Figs. 1, 2, a spool 15 rotatable about the drum axis, satellite storage drums 18 spaced from the drum 13 and freely mounted between the spool end plates and a spiral spring 19 coiled around each drum 18 with its free end attached to the drum 13. Each spring 19 is pre-stressed and tends to wind on to its associated drum 18 to rotate the drum, and hence the spool 15, around the drum 13. In a modified motor having five satellite drums 39, Fig. 4, one spool endplate has driving teeth 35 and the spool is held against rotation whilst a drum 40-fixedly held by a square winding spindle 33-is rotated to wind the springs thereon. A pawl and ratchet device 37 prevents backslip. In a cable &c. retrieving apparatus the cable (not shown) is normally coiled upon a spool 55, Fig. 5, in which position each spring 69 is coiled on its drum 68. On withdrawal of the cable the drums 68 rotate about a fixed drum 53 upon which winds each spring 69. On release of the cable the springs 69 return to the drums and the cable is rewound. Rotation of the spool 55 is limited by a non-rotatable nut 61 which moves along a rotating screw 59 until it meets either the screw head 60 or a pin 63. Rotation of the nut is prevented by the engagement of a slot in the nut with a spline 62 on the side of a bore 58.
