Title: Improvements in and relating to electromagnetic-acoustic signal devices
IPC: G10K9/15
Filed: 1950-03-10
Abstract: 681,480. Electric horns. GENERAL MOTORS CORPORATION. March 10, 1950 [March 11, 1949], No. 6040/50. Class 13 [Also in Groups XXXVI and XXXIX] In an electric horn comprising a diaphragm 102 which is permanently secured at its periphery by spot-welding to a base member 25 and carries a non-adjustable armature assembly 70, the required air-gap spacing between an armature 74 and an electromagnetic core is effected by electrically energizing the core so that it moves relatively to the armature against a temporarily inserted spacer, and then securing the core to the base by welding. As shown in Figs. 2 and 8, the electromagnetic core comprises a stack of E-shaped laminations 51 which carry a coil 62 and are clamped between steel plates 52, 53 having extended arms 55, 56, the core being permanently secured to the base after setting the armature air gap by welding the arms to lugs 29. The armature assembly is supported from a welded bracket 30 by a leaf spring. 77 and extends through a hole 61 in the core, the bracket also carrying an interrupter contact stack comprising contacts 91, 92 which are actuated by an adjustable nut 94. Sparking at the contacts is reduced by a shunt-connected resistor 35 which is attached to the base by an insulated rivet 39. The electrical circuit is arranged for earth return, the energizing lead 113 being connected to a bracket 82 which forms part of the contact stack. Also assembled in the stack are terminating plates 84, 86 for the internal coil and resistor leads [see Group XXXVI]. The diaphragm co-operates with a spiral horn assembly formed by two units 120, 121 which are secured together by integrally formed rivets. This assembly, together with an intervening gasket 127, is riveted to the base by rivets 128 two of which are threaded for mounting purposes. An upper cover 150 is secured to the assembly by bent-over tags 151. In assembly, the air gap is adjusted after the armature, diaphragm and base are fitted together, frequency adjustment being afterwards effected, if required, by applying axial pressure to the diaphragm centre. Alternatively the diaphragm may be fitted after the correct armature air gap is established by the use of a jig, Fig. 25 (not shown), which positions the armature correctly with respect to the base. Lugs 28 on the base are provided to hold the core in its correct position at the centre before it is secured by welding.

Abstract: 252,787. Brutzkus, M. March 5, 1925, Drawings to Specification. Mineral and tar oils.-The processes described in Specifications 149,915, [Class 1 (i), Chemical processes &c.]; 155,776; and 217,747, [Class 1 (i), Chemical processes &-c.], for carrying out reactions in the interior of a compressor are applied to the production of light oils suitable as motor fuel by the cracking and hydrogenation of mineral or tar oils, turpentine oils, pitch, fatty or other oils, resins, coal, sugar, molasses, starch, or cellulosic materials such as hay, straw or wood. Solid materials are injected into the compressor either in solution or in suspension in a liquid. For the hydrogenation, hydrogen or water gas or mixtures of hydrogen with lighting gas, blast furnace gases or gases obtained from coke, anthracite or lignite, may be used. The gases are compressed in an apparatus constructed like a Diesel engine, and liquids are injected into the gas during the compression or expansion stroke, of the piston according as the number of molecules are diminished or increased bv the reaction. Exothermic reactions are carried out while the gas is diminishing in temperature effected by expanding the gas, introducing cool hydrogenating gas or liquid. or cooling the walls of the compressor. Endothermic reactions are carried out while the gases are increasing in temperature effected by compressing the gases, introducing hot gases heating the walls of the compressor, or by electric or other heaters enclosed in the compression chamber. A catalyst may be arranged in an extension of the compression chamber. The operations of cracking and of hydrogenating may be carried out separately during different strokes of the piston or in different cylinders.

Abstract: 1,031,192. Gas turbine and jet propulsion engines. H. A. KERSHAW. Feb. 15, 1963, No. 6250/63. Headings F1G and F1J. In a thermal engine, for example a jet propulsion unit or gas turbine engine for fixed or transportable installations such as aircraft, electric power stations, ships, locomotives, road vehicles and rotary wing aircraft, comprising one or more continuous combustion chambers 9 receiving air compressed or partly compressed by a jet compressor 4, the latter is powered by a part of the working fluid from the combustion chamber or combustion chambers, or such derived from the exhaust of the associated power unit, which fluid is forced through a scoop device 12 and a conduit 14 to the nozzle 8 of the jet compressor 4. Part of the air compression may be effected by other means, for example by ram action. In order to increase the forcing effect of the gases, each scoop device 12 may be placed nearer to the turbine 20, placed at a slight angle to allow for deflection of the gas stream from the turbine 20, or increased in size. Each scoop device may be arranged in a combustion chamber and adjacent the turbine 20. Cooling of the combustion chambers is effected by cooling fins arranged longitudinally (as shown) or circumferentially of the chambers and cooled by the air stream during flight, entrained combustion air passed through a cowling 22 and ports 23 to the compressor 4 or cooling air, induced by a separate jet compressor, flowing through a cowling to a thrust nozzle. The engine is started by driving an airscrew 15, loosely mounted on shaft 20a, by a motor 16. In a jet propulsion unit, Fig. 1 (not shown), only one combustion chamber having a jet compressor and exhausting direct to a thrust nozzle is provided. This unit is started by an airscrew driven by an electric motor or by an air motor supplied with compressed air from a storage cylinder. The air motor may drive through a connection with the airscrew, ancilliary equipment such as a fuel pump, ignition generators and a mechanical air compressor for replenishing the storage cylinder, the airscrew, driven by the air drawn into the unit, continuing the drive once the unit has started. The airscrew may instead have a free-wheeling device. Water or water and alcohol mixture may be injected into the combustion or compressor chamber, either continuously or when required, to increase the power output.

Title: Improvements in the manufacture and production of nitriles
Filed: 1935-03-01
Abstract: Nitriles are obtained by treating aliphatic ethers with hydrocyanic acid at a raised temperature in the presence of a hydration catalyst; reagents which yield hydrocyanic acid under the reaction conditions, e.g., formamide or dicyanogen, may also be used.  Specified catalysts are oxides of barium, zinc, aluminium, silicon, titanium, thorium and zirconium, aluminium sulphate, phosphates and borates of aluminium, silver, cerium, cadmium, zinc, tin, uranium and iron, and zinc chromate and tungstate; the catalysts may be used in admixture with one another, or deposited on carriers, or in a gelled or peptized form.  The reaction may be effected at 200--500 DEG  C. and at atmospheric, raised or reduced pressure.  An excess of ether is preferably used, but the ether need not be pure; a part may be replaced by the corresponding alcohol, and a small proportion of water may also be present.  Examples are given in which (1) dimethyl ether and hydrocyanic acid yield acetonitrile; (2) diethyl ether and hydrocyanic acid yield propionitrile; (3) dimethylether and formamide yield acetonitrile; (4) dimethyl ether containing small proportions of methanol and water yields acetonitrile by reaction with hydrocyanic acid.

Abstract: 800,034. Twisting wires together. BLUNDELL, C. March 2, 1956 [March 7, 1955], No. 6564/55. Class 83 (4). [Also in Group XXIII] A wire coiling tool for joining the ends of wires has a slotted portion in which one of the wires to be joined can lie and a hole at right angles to the axis of slotted portion through which the second wire to be joined can be passed. Ends of wires 17, 18 to be joined are held in grooves 10 in a pair of pliers. The wire 18 is passed through a hole 19 in a die 13 of a coiler tool, the die 13 being pivoted on a rivet 14 to a handle 15 which is received in a slot 23 in the die allowing limited relative movement therebetween. The coiler is moved along a wire 18 until it contacts the pliers, Fig. 4, and is then turned about 90 degrees to the position of Fig. 5, to bend up the wire 18. The coiler is then twisted 90 degrees about its own axis, to the position of Fig. 6, so that the wire 17 passes through a slot 25, formed perpendicular to the hole 19, in the face of the die 13, and into a hook 24 in the handle 15. The coiler is then turned about the wire 17 to coil the wire 18 therearound to produce the first half of a joint 12, Fig. 3. The coiler is then released from the wire, the half coil thus formed is gripped in grooves 11 in the pliers and the process repeated to form the complete joint 12. The end of a wire may be coiled back on itself. To produce an end joint, Fig. 3b, in a multi-strand wire a modified coiler, Fig. 2b, is used. The wire 17 is bent back on itself and one of the strands unwound from the rest and passed through the hole 19 of the coiler, the wire 17 and the bent-back end, less the strand, being received in the groove 24. The strand is then coiled around the wire 17 and bent back end. Another strand is then unwound and coiled and so on until the last strand is coiled around the wire 17 only to form a tapered joint. According to the Provisional Specification the die 13 is not formed with the slot 23, the die being pivoted to one side of the handle 15, and movement of the handle 15 relative to the die 13 is limited by stops.

Title: Improvements in derricks or cranes
IPC: B66C23/60
Filed: 1922-03-06
Abstract: 198,759. Gray, A. G. March 6, 1922. Blocks acting on drums.-To check or control the slueing of a ship's derrick, guy ropes are led one to either side of the derrick and coiled around pulleys which, under the action of springs, counter-weights or the equivalent, keep both guy ropes taut, and the movement of the pulleys is controlled by brakes which are applied or released simultaneously. In a spring-actuated sheave with brake mechanism, the sheave f is connected to the fixed spindle h by a coiled spring i, and a brake block k normally held off by springs r may be applied by turning a cam-shaft o. When the sheave-blocks are at opposite sides of the derrick the two brake-mechanisms are controlled by a single lever near the winch. The two guy ropes may be led round guide-pulleys to coaxial sheaves controlled by cams on a single shaft o. In either arrangement the brakes may be normally off and may be applied to stop slueing, or the brakes may be normally on and released to permit slueing. The invention is more particularly applicable to derricks of the type described in Specification 178,964, [Class 78 (iv), Loading &c.].
