Means inter-connects the base of each transistor after the first stage transistor, to the collector emitter circuit of the preceding stage transistor whereby conduction of a transistor at one stage will place the base of the succeeding stage transistor at substantially earth potential to prevent conduction thereof. The number of stages is even whereby the final stage transistor 30 and the first stage transistor 24 conduct alternately. The system further comprises a step up transformer 98 having a primary winding 96 and a secondary winding 100, the primary winding being in the collector emitter circuit of the final stage transistor, a voltage dividing network connected to the power source and the base of the first transistor stage, the voltage available to the base via the network being insufficient to bias the first stage transistor to conduct, a photo-cell 48 between the voltage dividing network and the base of the first transistor, a light source 20, and means (not shown) to repetitively impinge light from the light source on to the photo-cell in timed relation to engine operation to energize the photocell whereby the photo-cell will develop a voltage which is added to the voltage of the voltage dividing network to bias the first stage transistor to conduct. Conduction of the first stage transistor 24 results in cut off of the final stage transistor 30 and collapse of the magnetic field in the primary winding 96 to  induce a voltage in the secondary winding 100 sufficient to fire a spark plug 102 of an internal combustion engine. Components of the circuit illustrated in Fig.2 are mounted within the housing of the distributor 106. A centrifugal advance mechanism is provided and this is also included together with a cup-shaped shutter wheel in the distributor housing.

Abstract: 532,539. Wetting &c. agents. FIFE, J. G. (Naamlooze Vennootschap De Bataafsche Petroleum Maatschappij.). Aug. 8, 1939, No. 22857. [Classes 2 (iii) and 15 (ii)] Dense aggregates of surface tension reducing substances, which do not scatter in the air and do not float on water are prepared by compressing and moulding the powders obtained by spraying solutions of the substances into hot gases. The products may be compressed more than once and may also be re-ground. The compression of the light powder may be effected on rollers, in eccentric presses, hydraulic presses or continuous screw presses, but it is desirable to enable the enclosed air to escape as soon as possible to avoid a large rise in temperature. Before compression, the powders may be mixed with inert fillers or modifying agents, e.g., a higher alcohol. Surface tension reducing substances are defined as organic substances of high molecular weight which reduce the surface tension of water and aqueous solutions, and the following examples are mentioned :-salts of acid sulphuric acid alkyl esters such as the alkali metal, alkaline earth, heavy metal, amine, sulphonium and phosphonium salts, sulphuric acid esters containing alicyclic or aromatic groups or hydroxy, nitro, amino, ether or ester groups, salts of phosphoric acid esters and sulphonic acid salts.
