Title: Improvements in or relating to fuel injection systems
IPC: F02D41/30
Filed: 1960-10-06
Abstract: 954,990. Transistor switching circuits. ROBERT BOSCH G.m.b.H. Oct. 6, 1960 [Oct. 7, 1959], No. 34241/60. Heading H3T. [Also in Divisions F1 and G1]  The operation of injection valves 21 of an engine 10 is controlled by transistors 32, 33 which are selectively fed with pulses from transistor 38, normally blocked together with transistor 37, by the conductivity of transistor 36 biased to conduct by a connection to the slider of potentiometer 55. The base of transistor 38 is earthed twice per revolution of the crank-shaft 19 by cam switch 63, 64, 65, causing its collector current to rise rapidly at a rate determined by resistor 70 and the inductance of a coil 40 whose core is positioned by a pressure gauge 43. The increasing current in winding 40 induces a voltage in secondary winding 50 which blocks transistor 36 and allows collector current in transistor 38 to be fed via amplifier 75 to transistors 32, 33 for a period determined by the inductance of winding 40. The duration time is further modified by additional circuitry (Fig. 5, not shown) to give (a) a curved duration-speed characteristic, (b) an increasing duration period during idling, and (c) additional duration time during acceleration produced by operation of the foot throttle control 45, by altering the bias voltage on the base of transistor 36 through feed-back circuits.

Title: Separation of carbon black from water
IPC: C02F101/10
Filed: 1975-08-18
Abstract: 1457379 Separating carbon black RUHRCHEMIE AG 18 Aug 1975 [23 Aug 1974] 34282/75 Heading C1A [Also in Division C5] Carbon black is separated from water by treatment with a hydrocarbon e.g. naphtha and the greater proportion of the hydrocarbon is separated from the resultant C black/hydrocarbon suspension in a plate separator. The process is particularly applicable to synthesis gas manufacture wherein oxygen 1 and fuel oil 2 are reacted and the resultant gas is freed from C black by scrubbing with water 4. The mixture of C black and water from the scrubber 4 is mixed with naphtha 8 in a decanter 7. The aqueous phase is separated and recycled 11 to the scrubber 4 and the hydrocarbon-C black suspension passed to a plate separator 10. The bulk of the hydrocarbon is separated and recycled 13 to the decanter 7. The C black residue containing 10-15% C black from the bottom of the separator 10 may be mixed with fuel oil and recycled to the reactor 3 or be distilled to recover pure hydrocarbon for recycle to decanter 7, the bottoms of such distillation being recycled to the reactor or used to recover dry C black.

Title: Improvements in electro-magnetically operated time lag devices
IPC: H01H71/44
Filed: 1920-12-04
Abstract: 176,483. Amberton, R. Dec. 4, 1920. Ordnance breech mechanism.-Consists in an electromagnetically operated device with a time lag, which may be used as the striker in percussion firing mechanism for ordnance. According to the invention, a magnetic core under the attraction of a solenoid moves in a totally enclosed vessel containing oil for restricting the movement; the core moves slowly under the retardation until the increased magnetic field causes rapid movement of the core and its container, as a whole. The device, as shown in Fig. 1 applied to a switch, comprises a brass tube closed at the lower end by a plug 15 and at the upper end by a steel cap 20 provided with a striker 21, 22. The tube is free to move upwards in a cup-shaped chamber 7 bolted to the magnet structure 4 and the position of its lower end may be adjusted by the cap 14 which raises and lowers a nut 11 upon which the tube rests. The tube contains a loose magnetic core 17 and the remaining space is wholly or in part filled with liquid. When the coil 6 is energized the core is raised slowly, the retarding liquid escaping to the lower end of the tube. After an interval, predetermined by the initial adjustment of the nut 11. the core reaches the cap 20 and in its further movement, which is rapid owing to the position of the core in relation to the coil, the core and its tube are carried together so that the striker 21, 22 operates the switch. On de-energization of the coil the tube and core fall, the core falling without retardation owing to the provision of the ball valve 18. The retarding means may be of the sucker type described in Specification 16846/04, 20468/08, [both in Class 38, Electricity, Regulating &c.], and 25606/12, [Class 38 (v), Electric switches &c.].

W., 8, Fernleigh Court, Preston Road, Wembley, Middlesex. Dec. 7, 1933, No. 34461. [Class 53] A carbon electrode for an air-depolarized primary cell is made from a mixture of finely divided carbon and sulphur or ammonium sulphate. The mixture is fired to drive off the inorganic material, the porous body so formed being subsequently treated to reduce its permeability to liquids without affecting its permeability to air. The mixture may also contain cellulose such as wood flour and an organic binder such as sugar, molasses or glucose and starch having its granules burst such as wheat flour treated with boiling water, together with oil or water. Before firing the mixture may be formed into an electrode by moulding, pressing, extruding, &c., and dried. Firing may take place at 900 to 1000‹ C. under non-oxidizing conditions such as by packing the formed and dried bodies in sand, plumbago or gas retort carbon. The fired bodies, after cooling, are impregnated with a colloidal solution of silicic acid in trichlorethylene, carbon tetrachloride or other volatile solvent. The finely divided carbon used in the process may consist of bone and wood charcoal and graphite. The wood charcoal may be made from beech or birch and the graphite may be made by heating coke in an electric furnace. The wood flour is made from pine. Any skin left on the surface of the fired blocks is removed with sandpaper or emery. Before being treated with the silicic acid solution a portion of the length of each electrode may be dipped in a solution of paraffin wax in petrol. The remainder of the electrode is then immersed in a solution of ammonium chloride, and the first portion again immersed in molten paraffin wax. After drying, the electrode is fitted with tinned copper straps bolted or clamped to the electrode and the top of the electrode is again immersed in molten paraffin wax. The lower part is then treated with the solution of silicic acid.

Filed: 1968-01-09
Abstract: 1,219,492. Corrugating. PIRELLI GENERAL CABLE WORKS Ltd. 30 Dec., 1968 [9 Jan., 1968; 25 July, 1968], Nos. 1266/68 and 35552/68. Headings B3A and B3E. Apparatus for forming annular corrugations in metal tubing comprises an annular corrugating member 1 supported so as to bear on the exterior of the tubing 3, means 5 for effecting relative movement in the direction of the longitudinal tubing axis between the tubing and the annular member, and simultaneously effecting relative rotation between the annular member 1 and the tubing 3, the internal working ridge 2 being of such curvature and configuration that, on passage of the tubing through the annular portion successive portions of the ridge, each having a radius of curvature equal to or greater than the external root radius of the tubing after corrugation, bear against the tubing in planes perpendicular to the longitudinal tubing axis to form successive annular troughs in the tubing. In operation, the annular member 1 is rotated eccentrically about the axis of the tubing 3 and at the same time the latter is advanced continuously through the member 1. Successive parts of the helical working ridge 2 engage and deform successive parts of the circumference of the tubing 3, the rate of feed of the tubing being such in relation to the rate of rotation of the annular member 1 that the advance of the tubing is maintained in step with the advance of the region of contact of the helical ridge 2 upon rotation of the annular member. As the leading edge of the ridge 2 finishes one trough the trailing edge of the ridge is just commencing the next trough. A trolley 9 which is free to move in a fixed line parallel to the movement of the sheath 3, is directly linked to a speed control rheostat 14 which varies the speed of the motors 5. The effect of this is such that if the trolley 9 moves towards an extruder 4 its speed is reduced by the rheostat 14 until it stops, alternatively, if the trolley 9 moves away from the extruder, the trolley speed is increased up to a certain set limit.
