Title: Improvements in or relating to holding magnets for electric switches
IPC: H01H9/56
Filed: 1953-02-25
Abstract: 728,616. Sparking preventing in switches. SIEMENS-SCHUCKERTWERKE AKT.-GES. Feb. 25, 1953 [Feb. 26, 1952], No. 5329/53. Class 38 (5). Switch contacts are held closed and released at a certain point in an A.C. cycle, e.g. at currentzero, by a magnet having an armature held by a steady flux, a release winding adapted to neutralize the steady flux, and an additional holding winding which is energized, e.g. by the current to be interrupted. The magnet comprises pole-pieces 2, 3 and cores 9, 10 between which is arranged a permanent magnet 8. The poles 2, 3 have apertures 6, 7 receiving the release winding 17 and are split at their upper ends to form four poles 42. The fixed contacts 18, 19 are carried by conductors 15, 16 arranged in the recesses between poles, and co-operate with a contact 14 carried by an armature 12 carried by springs 13. Normally, the steady flux of magnet 8 holds the contacts closed but when a release impulse is received by winding 17, the flux is neutralized to release the armature. The current through the contacts provides the additional holding flux which ensures that the contacts only open at current-zero, and so prevent operation due to mis-timing of the release impulse. The additional holding-flux may alternatively prevent release if the voltage is too high or if the speed of a motor, controlled by the switch, is too high. The steady flux may be provided by a D.C. winding, and the armature may, instead of carrying contacts, trip a switch. The contacts are held open by a similar magnet 1<SP>1</SP>and are released when the latter is de-energized by an impulse winding 17'.

Title: Improvements relating to fuel-pump regulating means for injection-type internal combustion engines
IPC: F02D1/00
Filed: 1950-03-08
Abstract: 690,555. Fluid-pressure servomotor control systems. DAIMLER-BENZ AKT.-GES. March 8, 1950 [March 8, 1949], No. 5888/50. Class 135 In a hydraulic regulating means for the fuelinjection pump of an internal-combustion engine, fluid at a pressure dependent upon engine speed acts on one side of a regulating piston, against a resisting force, in the direction for increasing the quantity of fuel injected, but, when the said pressure exceeds a value predetermined by the driver, a valve-controlled passage through the piston is automatically opened and regulating fluid passes to the opposite side of the piston to augment the resisting force acting thereon to urge the piston in the direction for reducing the quantity of fuel injected. In an embodiment, the cam shaft 2 driving the fuel-injection pump pistons 3 also carries an eccentric disc actuating the reciprocating pistons of a separate combined fuel and governor pump. The input to the latter pump is drawn from the main pump housing and a low pressure output is fed to the suction space 37 of the main pump. A second output at a higher pressure corresponding to the speed of the engine is fed to a chamber 15 where it can act on a piston 9 connected by links and a lever 7 to the rack controlling the output of the main pump. The liquid in chamber 15 also flows through restrictions 16 into the interior of telescoping tubular sections 11, 13 where it can act on a relief-type valve 20. On starting the engine, the piston 9 is forced to the right to its limiting position to give full output from the main pump. If the spring loading of valve 20 has been set by hand lever 23 to give idling conditions, the pressure in chamber 15, &c. will soon overcome the spring loading of valve 20 and will open the latter so that, besides venting chamber 15, the liquid also flows to the back of piston 9 to assist the loading spring to force the piston to the left and so reduce the output of the main pump. The engine can be set for higher speeds by increasing the spring loading on valve 20 by means of lever 23. Tube 13 is fixed to the casing containing piston 9. Both sides of the piston 9 are continuously vented through restrictions 27, 28, and restriction 16 may constitute a valve which does not open until the piston has moved some distance to the right.

Title: Process for purifying finely divided carbon black which has been formed on iron-containing contacts by decomposition of carbon monoxide
IPC: C09C1/56
Filed: 1936-02-28
Abstract: Carbon black obtained by the decomposition of carbon monoxide using iron-containing catalysts is freed from iron, particularly in the form of iron carbide, by treatment with chlorine, hydrogen chloride or mixtures thereof, which may be moist, at temperatures between 400 and 1250 DEG  C.  The process may be carried out in a crucible furnace or in a rotary tube furnace, the temperature preferably being increased towards the end of the reaction to remove the chlorides formed, together with intermittent or complete stoppage of the chlorine stream.  The reaction products may also be removed by a stream of inert gas or in vacuo. Preferably however, the carbon black is scattered through a uniformly heated stream of chlorine &c., removing in countercurrent and final removal of chloride and adsorped chlorine is obtained by spraying through an inert gas atmosphere, e.g. hydrogen or nitrogen, with the addition of steam if required. The unused chlorine &c., may be recycled.  The impurities (up to 6 per cent) may be reduced to about 0,1 per cent, and the product is suitable for use in the printing ink, lacquer or rubber industries.
