Filed: 1972-03-20
Abstract: 1424531 Moulding pipeline pigs MERCOL DESCALING CO Ltd 22 March 1973 [20 March 1972] 12980/72 Heading B5A [Also in Division F2] A method of making hollow pipe spheres used for separating different fluids whilst being pumped through a pipe comprises forming two identical hollow half spheres from an elastomeric material formed by chemical reactions between its constitutents and placing the two halves together to form a whole sphere before the chemical reactions have been completed so that chemical reaction including cross-linking subsequently occurs across the interface to form a monolithic hollow sphere. Excess material may be cut from the half spheres before they are placed together. Additional reactive mixture may be placed on one or both half spheres before they are placed together to eliminate the effects of surface roughness and air pockets. Each half sphere may be in the form of a gel which is formed by pouring a mixture of an ethylene propylene adipate/diphenylmethane di-isocyanate prepolymer and 1 : 4 butane-diol into a mould.

Filed: 1958-04-25
Abstract: 849,638. Grinding. BROOKES (OLDBURY) Ltd. April 17, 1959 [April 25, 1958], No. 13181/58. Class 60. A grinding machine, e.g. for removing scale from billets, comprises a machine bed 10, means for traversing a work piece 12 longitudinally along the bed, a slide 15 movable transversely of the bed, a grinding head 16 pivotally mounted in the slide 15 about an axis parallel to the direction of movement of the workpiece, the head 16 including a grinding wheel 17 rotatable about an axis parallel to the pivot axis, and being biased in a direction to move the grinding wheel away from a workpiece on the bed, and fluid actuated means for moving the grinding head in opposition to its bias whereby the grinding wheel can be held in contact with a work piece being traversed along the bed. The workpiece 12 is supported on a carriage 11 longitudinally traverseable, e.g. hydraulically, on the bed 10. A fixed support 13 has guides 14 on which the slide 15 is traversely traverseable, movement through an appropriate distance being effected, by hand or automatically, at each reversal of the carriage 11. A duct 19 in the support 13 receives and conveys away dust &c. from the grinding. The grinding wheel 17 is driven by a motor 18 mounted on the grinding head 16. A cylinder 20 connected to the grinding head 16 contains a piston connected to the slide 15. The cylinder 20 is connected to a source of pneumatic pressure through an expansion chamber, so that whilst the grinding wheel is held in contact with a workpiece it can rise and fall to accommodate itself to irregularities in the workpiece surface without materially varying the pressure with which it bears against the workpiece. A safety device to raise the grinding wheel quickly in the event of the workpiece being traversed from under it comprises a cylinder 21 connected to its grinding head and containing a piston connected to the slide. The cylinder has an outlet through which fluid can escape at a predetermined rate as the grinding wheel moves downwardly. The cylinder 21 is also connected to a pressure responsive means whereby the admission of pneumatic pressure to the cylinder 20 is reversed in the event of the pressure in the cylinder 21 exceeding a predetermined value.

Title: Improvements in and relating to radio signalling systems
IPC: H04L27/04
Filed: 1919-05-27
Abstract: 154,247. British Thomson - Houston Co., (General Electric Co.). May 27, 1919. Wireless signalling.-In a method of controlling the amplitude of the emitted waves by varying the effective resistance of the antenna circuit without varying its natural frequency, the depression of the transmitting-key varies the saturation of one or more magnetic amplifiers of the kind described in Specification 7151/13, which are so associated with condensers that the variation in the inductance in the individual amplifier does not materially effect the tuning of the antenna circuit. In the arrangement shown in Fig. 1, the parallel windings 8, 9 of the amplifier are in series in the antenna circuit with the condenser 14 and arc generator 1. A condenser 12 and ohmic resistance 13 are arranged as shown. When the key 11 is raised, a constant saturating current is applied to the amplifier, so that the loop circuit formed by the condensers 12, 14 and inductance of amplifier 7 is in tune with the transmitter waves, and the resistance 13 is not shunted to any effective extent. The depression of the key increases the saturating current through the amplifier by shortcircuiting resistance 15, reducing the inductance to a value which with the condenser 14 forms a shunt circuit of zero reactance around the resistance 13, thus increasing the energy radiated. In the arrangement shown in Fig. 2, two similar amplifiers 7, 17 are arranged in shunt to condensers 12, 16, the key 11 normally saturating the amplifier 17. In this condition, the loop circuit formed by amplifier 7 and condenser 12 becomes substantially non-reactive but forms a high impedance in the antenna circuit. A circuit formed by the amplifier 17 and condenser 16 is also non- reactive. When the key 11 is depressed the resultant inductive impedance of the circuit formed by the amplifier 17 and the condenser 16 neutralizes the resultant capacity impedance of the circuit formed by the amplifier 7 and the condenser 12, but the effective resistance of the antenna circuit is much less and energy is radiated. The arrangement shown in Fig. 3 differs from that shown in Fig. 2 in that the capacity 16 instead of being in shunt with the arc is in series therewith. In this arrangement, as soon as the impedance of the control circuit becomes large, that is when the key 11 is in the position shown, the arc current falls off. A condenser 21 is provided to prevent the arc current from being completely interrupted.

Title: Continuous casting mould and lubrication method therefor
IPC: B22D11/07
Filed: 1950-05-26
Abstract: 686,413. Continuous casting-machines. SANKEY & SONS, Ltd., J. March 13, 1951 [May 26, 1950], No. 13373/50. Class 83 (i). In a method of continuous casting a combustible gas or liquid containing carbon together with an air supply insufficient for complete combustion is introduced between the wall of the mould and the newly-formed skin on the congealing metal so that carbon is deposited and serves to lubricate the passage of metal through the mould. The mould comprises two similar mould sections 10, 18 and between them a lubricator section 28 all having aligned vertical passages for the metal. Each mould section has upper and lower outwardly-directed flanges 10b, 10c surrounded by a cylindrical shell 11 to form an annular chamber 12 with inlet 13 and outlet 14 for cooling water. Sealing rings 15 are interposed between the shell and the flanges. In the region of the flanges, the shell is supported and positioned by arcuate shoes 26 which bear against the outer surface of the shell and are yieldingly pressed inwards by means of springs 25b and bolts 25 mounted in a surrounding frame 23 comprising a top ring 23a, a bottom ring 23c and three equally-spaced posts 23b. The lubricator section comprises two cooling chambers 35 and two chambers 29, 32 communicating by radial passages 31, 34, respectively, with the metal passageway. In order to assist the passage of the casting through the mould there is introduced into the chamber 29 and ports 31 a material from which lamp black may be produced, such as petroleum, turpentine resin, a paraffin hydrocarbon such as methane or ethane or a hydrocarbon of the olefine series such as ethylene or a hydrocarbon such as acetylene. Air in an amount insufficient for complete combustion of said material is introduced into the chamber 32 and ports 34, finelydivided carbon thus being produced between the mould and casting. A seal 39 of asbestos impregnated with graphite prevents the lubricant materials from passing out of the mould at the lower end. Alternatively the lubricant may be introduced as oil vapour or colloidal graphite dispersed in carbon tetrachloride and carried along with a stream of gas such as nitrogen, hydrogen or acetylene. Acetylene may be introduced alone, the heat of the metal causing it to break down to deposit free carbon. If hydrogen or acetylene is introduced at one set of ports, nitrogen may be introduced at the other to act as a diluent and a scavenger. Intermittent puffs of nitrogen may be used to free the ports of deposited soot and to free the metal skin from the mould wall. Specification 686,322 is referred to.

In an artificial communications satellite of dumb-bell configuration a first capsule 11, Fig. 1 (not shown), contains a nuclear power plant, and a second capsule 10, which is separated from the capsule 11 by a boom 8, contains instruments and electrical equipment and carries a directional aerial 14 comprising a fixed reflector 15, Fig. 3 (not shown), faced by four symmetrically disposed horn radiators 16, 17, 18, 19. Each horn has a discharge gap 21 and is connected to a common feeder waveguide 20 containing matching diaphragms. The axis of the satellite normally points to the centre of the planetary body around which it orbits, but any deviation owing to, for example, the impact of meterorites, is detected by sensors, which cause the distribution of energy between the horn radiators to change so that a compensatory angular movement of the axis of the radio beam takes place. Gyroscopic or infra-red sensors may be used in conjunction with trigger circuits to operate the discharge gaps 21, which regulate the outputs from the horns 16, 17, 18, 19. The said outputs can also be regulated in other ways, for example, capacitatively or by phase control.

Filed: 1945-05-29
Abstract: 619,130. Fluid-pressure servomotor-control systems. GROVES, M. V. May 29, 1945, No. 13453. Convention date, March 10, 1944. [Class 135] [Also in Group XXXIV] The casing 16 of the control valve of a fluid-pressure brake system is secured at 12 to a stationary member, the rod 20 being actuated, e.g. by a pedal, to move the piston towards a larger piston 46, the exhaust valve 53 being thereby seated to shut off the passage 60, connected to the reservoir, from the hydraulic pressure spaces. The piston 43, at the same time, slides over a pin 40 against the action of a spring 42, to shut a valve 38 which controls the exhausting of the space 36, and to open a valve 35 to admit pressure-fluid from the pump connection 21 to the space 36. The main valve 27 is thus forced to the right, against the spring 28 thereby opening direct communication between the pump and the port 34. A hose 62 transmits the pressure-fluid to a perforated check-valve 66 which is forced against the spring 68 to open the port 65 leading to the brake cylinders and to isolate this port from the port 56 connected to the pressure reaction pipe connected to the brake cylinders. The true brake cylinder pressure is thus admitted to a space 52 between the pistons 43, 46, the pressure on the piston 43 giving " feel " to the operator, and the pressure on the piston 46 moving it against the spring 59 to produce a lapped condition of the valves. When the operator releases the rod 20, the piston 43 is returned by the pressure in the chamber 52 and by the spring 59 which returns the piston 46, the valve 53 remaining seated until the piston 43 moves away from the piston 46, allowing the exhaust valve 38 to open and the power valve 27 to close. The fluid is then returned from the brake cylinders through the passage 49, 50 to the reservoir R.
