Title: Improvements in or relating to the scavenging and exhaust systems of two-stroke internal combustion engines
IPC: F02B25/00
Filed: 1945-11-05
Abstract: 613,842. Two-stroke engines. ARMSTRONG WHITWORTH & CO. (ENGINEERS), Ltd., SIR W. G. Nov. 5, 1945, No. 29389. Convention date, Nov. 3, 1944. Drawings to Specification. [Class 7 (ii)] In a two-stroke engine in which the charge is induced by the outflow of exhaust gases, this outflow is arranged so that the return movement caused by shock in the exhaust passage causes swirl of the charge. This is produced by tangential outlet passages having ports controlled by the piston, a sleeve or a poppet valve. In one arrangement, tangential piston-controlled ports lead to a chamber extending round the cylinder, and progressively decrease in height, the first opened being situated farthest from the exhaust pipe. In another arrangement, four overhead exhaust valves lead in pairs to two tangential exhaust passages. The inlet ports and passages may also be tangential and arranged to swirl the ingoing charge in the same direction as that caused by the return movement of the exhaust gases. Specification 479,512 is referred to.

Abstract: 717,652. Switch contacts. MAKEPEACE CO., D. E. Nov. 24, 1952. No. 29656/52. Class 38(5) [Also in Group XXII] A method of making an electric contact comprises bonding a plug in a bore of a base metal strip, said plug being formed from a laminated stock having a precious metal top layer and a bottom layer of solder and forming a small projection in the bonded assembly of the plug in the strip so that the outer surface of said projection constitutes said precious metal. A metal strip 10 of copper, nickel, brass, bronze or nickel-silver is punched with a series of holes 11 for receiving a precious metal contact point the location and number depending upon the shape and construction of the electrical contact element. A series of centering holes 12 are also punched in the strip parallel to an edge the holes being spaced apart by a distance equal in length to the length of strip needed to form one contact element. A flat laminated metal plug 13 is punched out from a laminated metal strip comprising a base layer b of similar metal to that of the strip 10, a top layer c of precious metal e.g. gold, silver, platinum, palladium or their alloys and a bottom layer a of solder. The layer c may be electroplated on the layer b or they may be welded together by pressure welding, brazing or soldering. Alternatively the strip may consist entirely of precious metal with a film a of solder on one side. The plug is placed in the bore 11 and the assembly is then heated in a furnace to bond the plug in position. The finished contacts 25, Fig. 5, are formed from the assembled strip by stamping, drawing and cutting operations.

Title: Rotary ground drilling rigs
IPC: E21B7/02
Filed: 1975-07-03
Abstract: 1464018 Boring earth &c LIND PILING Ltd 3 July 1975 [4 July 1974] 29717/74 Heading E1F A driving unit 8 for a rotary ground drilling rig, e.g. using a ground auger (not shown), includes a frame 19 which carries a rotary table 18 having a driving ring gear 17 and a number, eg four, of piston type hydraulic motors 14, 15 each of which drives a pinion 16 meshing with the ring gear 17 and some at least of which have remotely controllable devices for reducing the swept volume of the motors to zero. As described the driving unit has three motors 14 with remotely controllable devices for reducing their swept volume to zero and a single motor 15 whose swept volume can be reduced to a fraction of its maximum value. The motors 14, 15 are supplied with hydraulic fluid from a hydraulic power output, e.g. power pack 12, through a supply circuit including lines 23 connected to the motors 14, the lines 23 containing cut-off valves 21 and lines 24 connected to motor 15, the lines 24 being connected directly to the supply 12. In use, when drilling, all the motors 14, 15 are used to provide maximum torque and a low speed of rotation of the auger. To remove spoil from the auger after it has been raised from the hole, the swept volume of the motors 14 are reduced to zero and cut-off valves 21 are closed so that the entire output of the hydraulic supply passes through motor 15, thus rotating the auger at high speed (but at low torque). The speed of motor 15 can be further increased by reducing its swept volume. By closing valves 21 and reducing the swept volume of motors 14 to zero, the drag exerted by motors 14 is minimised, thus permitting the motor 15 to rapidly accelerate the auger to its maximum speed of rotation. The auger (not shown) is mounted on a kelly bar 3 which is driven by keys 20 in the rotary table 18 and which is suspended from a cable 4 passing over jib 2 on a mobile crane 1. The driving unit 8 is mounted on arm 10 pivoted to the crane at 9.

Title: Process for the recovery of carbon disulphide from industrial effluent waters
IPC: D01F13/02
Filed: 1937-11-04
Abstract: Carbon disulphide is recovered from industrial effluent waters by blowing the carbon disulphide out of the waters with air or other gases, and extracting the carbon disulphide from the current of air or gas by treatment with wash oils or adsorbent media such as active carbon or silica gel.  The current of gas employed may be the outgoing air of the spinning or washing baths of the rayon industry or, alternatively an inert gas such as nitrogen or producer or combustion gases may be employed.  The contact of liquid and gas is preferably effected in counter-current in a spray tower.  If the air or gas after contact with the liquid also contains acidic gases such as hydrogen sulphide or sulphur dioxide, these may be eliminated by washing with basic chemical liquids or with water.  The carbon disulphide may be recovered from the wash oils or adsorbent media by treatment with steam, preferably after displacing the air in the adsorbers with an inert gas.

Abstract: 876,888. Rectifying, automatic speed-control systems. IGRANIC ELECTRIC CO. Ltd. Sept. 23, 1958 [Sept. 23, 1957], No. 30329/58. Classes 38 (2) and 38 (4). [Also in Group XXXVII] A three-phase rectifying arrangement 2 for supplying a D.C. motor comprises uncontrolled rectifiers 6, 8, 10 and controlled rectifiers 12, 14, 16, which includes resistors 24 ... 34 in their anode circuits. Three mains-fed transformers PT1, PT2, PT3 supply heaters and a rectifying bridge 44 providing at 44d, 44e a D.C. output for a shunt field winding S.H.F. and a speed-control rheostat 52. The output from the rectifying arrangement 2 is supplied from terminals 38, 40 to an armature A through a resistor 54 and contacts F1, F2 or contacts R1, R2. A potential divider 58, 60 is disposed across the D.C. supply voltage, and the voltage at 59 which is indicative of armature speed is applied to a potential divider circuit across the rheostat 52 so that the potential of the arm 52a relative to the line 40 is determined. The voltage together with a D.C. voltage derived from network 103 and A.C. voltages derived from transformers PT4, PT5, PT6 is fed to the grids of the valves. The position of the arm 52a determines the speed of the motor. The circuit 103 provides compensation for varying load current and comprises an arrangement whereby a D.C. voltage is obtained from the rheostat 114 which is dependent on the current through the resistor 54. A contact arrangement shown generally at 91 is supplied from a transformer PT7 and includes a time delay device TR which operates contacts TR1 whence coil CR and contacts CR1 and CR2 operate and coil DB operates dynamic braking contacts DB 1. Thereupon operation of the forward contacts completes a circuit through contacts F1, F2, holds F through F4, and breaks the supply to coil DB through F5. F3 is also opened which disconnects resistor 62 from the point 70 thereby applying a positive potential to the grids to effect conduction. The instant of application of this potential is delayed whilst a capacitor 84 charges up. Similar operation arises for reverse actuation. A coil VR is provided to prevent rapid reversal of the motor. In another embodiment (Fig. 3, not shown) the controlling voltages are applied to the grids of a further set of valves whose anode loads control the grids of the valves 12, 14, 16.
