Filed: 1966-07-19
Abstract: 1,091,580. Jointing by forging. CABLE COVERS Ltd. July 19, 1966, No. 32296/66. Heading B3H. [Also in Division D1] A joint is formed between two wire or cable strands 8 by swaging a ferrule 2 over the wires and simultaneously forming at least one end of the ferrule to frusto-conical shape 10, the axis of the ferrule bore at that end being parallel to but offset from the bore axis at the opposite end. The ferrule is made of steel and is swaged between dies. The invention may be used for forming a terminal eye or loop 1 on a cable or for securing together two cables (16), (18), Fig. 5 (not shown). In the latter case frusto-conical portions are formed at both ends of the ferrule.

Abstract: 399,665. Centrifugal pumps. WEIR, Ltd., G. & J. and SIM, J., Holm Foundry, Cathcart, Glasgow. Nov. 16, 1932, No. 32367. [Class 110 (i).] A centrifugal pump of the liquid-ring type comprises a rotary casing 1 combined with an impeller having vanes 7 which is mounted on a vertical shaft 15 and driven by an electric motor. A stationary disc 8 covers the vanes and has a flange 9 extending downwards around part of the periphery of the impeller. A fixed scoop 11 entrains liquid and leads it through a port 12 into the vanes to expel air or gas contained in the inter-vane spaces through outlet ports 6<1>, 6, 27, 28, into the casing 21 which communicates with the atmosphere. The impeller afterwards discharges the liquid when outside the arc 9 and the cycle is repeated. Air enters by way of ports 26, 5, 5<1> to the intervane spaces. A roller bearing 19 supports the upper trunnion 18 of the rotating casing. Liquid spilled through the port 28 is caught in a gutter 31 leading to a drain 32. Make-up liquid may be supplied through a port 30 and the priming liquid through a port 30<1>.

Patent GB-358756-A (GB)
IPC: C01B25/30
Filed: 1930-10-30
Abstract: In obtaining alkali phosphate by the interaction of alkali sulphate and ferrophosphorus of high phosphorus content, the decomposition is effected under reducing conditions in the presence of substances containing free carbon or coal, in such amount as to prevent the formation of sulphur dioxide.  Thus, in the reaction between sodium sulphate and ferrophosphorus containing 22 per cent phosphorus in the presence of coal, a melt of sodium phosphate and iron sulphide and oxide is produced, which is subsequently lixiviated.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the treatment of metal-phosphorus alloys generally, and also the use of metallic and non-metallic, organic or inorganic reducing agents.  This subject-matter does not appear in the Specification as accepted.

Abstract: 521,273. Pressure gauges. SMITH & SONS (MOTOR ACCESSORIES), Ltd., S., and MOSS, E. B. Nov. 10, 1938, No. 32743. [Class 106 (ii)] [Also in Group XXII] A capsule of the kind comprising two flexible corrugated diaphragms joined together at their peripheries have the corrugations so mated together that there is practically no space between them when the capsule is in the compressed condition. The capsule is produced from two blanks 10, 11 of identical dish-shape soldered at their peripheries 12, 13. a hole 14 being provided for communication to the interior. The assembly is then submitted to the action of press tools to form corrugations 15 which may be circular and V-shaped in section rounded top and bottom. The diaphragm may be joined together after corrugating and sealed by means other than soldering. A plurality of interconnected capsules may be employed in a stack and in this case the corrugations may be formed while they are superimposed in a single pressing operation.

Filed: 1939-12-22
Abstract: 534,724. Oil engines. KAMMER, G. S. Dec. 22, 1939, No. 32785. [Classes 7 (iii) and 7 (vi)] An injector nozzle is fitted with two or more needle valves 1 which admit fuel respectively to annular slits 14, 17 leading to apertures 14a, 17a formed at different levels around a cap 16. The slits 14, 17 are formed by annular recesses in washers 13, 15 inserted between the injector body 2 and cap 16. The passage 11 from one valve 1 leads to grooves 12 and an annular groove 12a communicating with the slit 14, while a corresponding passage from the other valve 1 leads to further grooves 12b communicating with the slit 17. The valves 1 are opened successively by fuel pressure admitted at 5, 6, when the pressure admitted at 7 to pistons 3 on the valves is relieved. This is effected by distributing-valves 18, Fig. 5, as described in Specification 531,133, which are moved between upper and lower seatings by a cam 20, thereby connecting a passage 23 from the pistons 3 either to fluid pressure at 19, or to a discharge at 24. The cam 20 is adjustable axially, being tapered as shown in Fig. 5, and is resiliently mounted as shown in Fig. 6.

Filed: 1971-07-13
Abstract: 1383746 Valves AUTOMOTIVE PRODUCTS Ltd 20 June 1972 [13 July 1971] 32878/71 Heading F2V A valve for connection between working chambers of a piston/cylinder arrangement to damp the piston against pressure fluctuations comprises a pair of spools 31, 33 at one end of the valve, a pair of reciprocating members 29, 32 at the other end of the valve, the pressure of chamber 12 being communicated to both ends of the valve and to chamber 13 whenever the land 51 of spool 33 uncovers the port 48. Normally an increase in pressure in one of the chambers 12, 13 to move the piston 14 causes the spools 31 and 33 to move in unison. Should the rate of increase in pressure in the one chamber exceed a predetermined value, a differential movement of the spools occurs by virtue of a dashpot 25 to connect the chambers 12, 13 together. In an alternative arrangement (Fig. 2, not shown) the pressure from one chamber (62) is applied to one end which forms a dashpot (94) and pressure from the other chamber is applied to the other end (68) unrestricted.

The coated grains may be mixed with a temporary binding agent to agglomerate them and they may be spread on a metal or sintered metal, e.g. Ni, support prior to sintering.  The sintered electrode may be rendered impermeable by immersion in a suitable liquid e.g. 10% by weight solution of petroleum wax in kerosene.  The metal coating exemplified is silver and the method of coating is to suspend active carbon in a solution of ammonical silver nitrate which is stirred and heated to 50 DEG  C. and add formaldehyde thereto.

Abstract: 307,121. English Electric Co., Ltd., and Schroeder, G. Dec. 9, 1927. Alternating-current induction machines; rotary transformers.-In an arrangement for regulating an induction motor or other asynchronous machine by means of a commutator frequency converter driven at a speed proportional to that of the asynchronous motor and having no stator field windings or only commutating windings on its stator, the converter is provided with pairs of brushes movable relatively to each other for speed regulation, the voltage between the brushes being applied directly to a winding on the motor under regulation. In addition, all the brush sets may be moved together for phase regulation. In the form shown in Fig. 1, the three-phase secondary windings 3, 4, 5 of the main induction motor 1 are brought out on each pole to rings 6 which are connected to brushes on the commutator 14 of the frequency transformer 15. This consists of an unwound stator with a closed winding symmetrically tapped to six rings 16 connected to the supply through a transformer 18. Speed regulation of the main machine 1 is effected by moving brushes 7, 9, 11 in one direction and the brushes 8, 10, 12 in the other, and phase regulation by moving all the brushes together in the same direction. Fig. 2 shows the application to a frequency transformer having shunt and series commutating windings. In this case, the frequency converter is provided with two commutators, one at each end of its rotor, and the stator is divided into two parts capable of independent rotation, each with one of the brush sets. The secondary windings 3, 4, 5 are connected respectively to the brush pairs 7-8, 9-10 and 11-12 on the two commutators 19, 20 through the series commutating coils 22, 24. The twopart stator carries movably the auxiliary shunt coils 21, 23 in addition to the series coils. Speed regulation of the main motor 1 is effected by turning the two halves of the stator, together with the brushes and stator coils, in opposite directions and phase regulation is carried out by moving the two halves &c. in the same direction.
