Abstract: 1476887 Ignition systems ROBERT BOSCH GmbH 5 May 1975 [23 Nov 1974] 18699/75 Heading F1B An ignition system for an internal combustion engine includes an ignition capacitor C1 for storing the energy required for ignition, the capacitor being arranged to be charged from a direct current source B by way of a voltage converter 10 and discharged by way of the primary winding 11 of an ignition coil 12 whose secondary winding 16 is connectible to a sparking plug (not shown) and whose primary winding is connected in series with the switching path of a controllable rectifier 14 which can be rendered conductive by the opening of a contact breaker 13 mechanically operable by the internal combustion engine and a control circuit S which is actuable by the contact breaker and which comprises a monostable multi-vibrator MV, a voltage divider R5, R6 connected between an operating current supply line 19 and the charging side of the ignition capacitor, a Zener diode ZD connected to the tapping of the voltage divider and a power transistor T2 whose base is connected to the Zener diode and which during the unstable switching state of the monostable multi-vibrator is arranged to become conductive whenever the voltage at the ignition capacitor attains a value determined by the Zener diode and the voltage divider and to then render the controllable rectifier 14 conductive in order to produce at least one additional ignition spark. The stable period of the monostable multi-vibrator MV and/ or the control level at the tapping point of the voltage divider are controllable in dependence upon one or more operating parameters of the engine. The parameters may comprise the engine speed and/or the battery voltage and/or the manifold vacuum.

Title: A process for the production of alkali hydride
IPC: C01B6/04
Filed: 1927-07-15
Abstract: 276,313. Deutsche Gold-und Silber- Scheideanstalt vorm. Roessler. Aug. 23, 1926, [Convention date]. Alkali hydrides are prepared by passing hydrogen at temperatures above 200‹ C. over alkali metal such as sodium distributed on a solid diluent such as common salt, iron powder, sodium carbonate, wood charcoal, &c. The metal and diluent may be ground together, or may be mixed at a temperature above the melting point of the metal. The reaction may be carried out in a slightly inclined rotary tube down which the mixture passes against an upward current of hydrogen which may contain inert gases, and the tube or the current of gas may be heated. The treatment may be commenced by passing alkali metal and diluent into the tube, and subsequently passing only alkali metal, in which case the hydride serves as diluent for the metal.

Abstract: 693,834. Dynamo - electric machines. MINISTER OF SUPPLY. July 23,1951 [Aug. 1, 1950], No. 19155/50. Class 35. Converting electric energy into motion of fluids by the action of magnetic fields.-In a pump which produces motion of a conducting liquid by the interaction of electric current and a magnetic field, the active current passes back through the gap in the iron circuit to prevent distortion in the distribution of the flux and current. In its simplest form, Fig. 3, the liquid flows along a flat duct 31, through which flux is passed vertically between polepieces 36, 37, while current passes from terminal 34, horizontally through the conducting liquid between insulating top and bottom members 33 and, leaving the liquid at electrode 35, returns by flat conductors 38, 39 to the other terminal 34a. In a more compact form, the return conductors are internally insulated, e.g. by varnish or refractory oxide and the top and bottom members of the tube are dispensed with. In a further modification, Fig. 5, the current, which enters at terminal 53 leaves the liquid at electrode 54 and returns to the other terminal 57 by a series of conductors 56 passing through slots 55 in the top polepiece 51. In Fig. 6, both directions of current flow are used to exert pumping action. The current passes from terminal 63 through the liquid in duct 60, through interconnector 64 to duct 61 and leaves by terminal 67. The ducts are joined by a loop 62 so that the liquid flows serially through the two ducts. In a modification, transverse flux is further reduced by spacing the ducts from each other and placing a stack of magnetic laminations between them so that flux can pass directly between them but not obliquely. The curvature of the flow path may in this way be reduced so that in the extreme case of Figs. 8 and 9 the liquid and current flow paths are in the same plane. In Fig. 8, the liquid flow path is straight along duct 81 and the laminated section 85 joins the two active sections, current passing from terminal 82 to terminal 83 through interconnector 84. In Fig. 9 the duct is looped at 90 so that the current path may be straight from terminal 93 to 95. Specifications 528,091, 557,986 and 567,772 are referred to.
