The contactor 31<SP>2</SP> is connected to an inductance 42 and resistance 44. In an alternative system the cam and contactor units 2, 4, 6 and 8 are omitted and one of such units is replaced by a cam and contactor unit including a four lobe cam. The system may be used when the speed at which the magneto is driven is increased to secure a higher magneto output voltage, the unwanted pulses being dissipated. A magneto for an 8-cylinder engine may be used with a four cylinder engine unused pulses being dissipated. The winding of the inductance may be composed wholly or partially of resistance wire.

Abstract: 1,050,208. Cyclic adsorption - desorption process. ESSO RESEARCH AND ENGINEERING CO. July 20, 1964, No. 29483/64. Heading B1L. Zone X adsorbs a component A from a feed gas at high pressure and passes a component N as a primary effluent of which some (e.g. 50%) is fed to desorb zone Y by reverse flow, at low pressure, some of the secondary effluent leaving zone Y, richer in A than is the feed gas, being compressed and returned to zone X. Periodically valvesx, y are closed and opened to reverse the roles of the two zones. The feed gas enters zone X or Y at an intermediate point, where the rising secondary effluent will have lost enough A to correspond to the feed gas composition. The first secondary affluent leaving zone Y may be vented or recovered as it contains mainly A. Component A may be condensed out and removed upstream or downstream of compressor 3. The newly compressed secondary effluent may heat the primary effluent leaving pressure-reducing valve or orifice 7, or the expanding gas at 7 may drive the compressor. The valves x, y may be solenoid-operated, timer-controlled. In Fig. 2 (not shown) each zone comprises two beds in series and the feed gas flows only through the upper bed of each. The beds may operate at different pressures and contain different adsorbents. The process may be used in removing hydrocarbons (e.g. methane) from hydrogen (e.g. in refinery tail gas) or for drying hydrogen and a guard chamber 45 containing adsorbent may remove the heavier hydrocarbons from the feed gas. The chamber 45 is periodically regenerated by flushing, steaming or vacuum-desorbing. At the end of an adsorption step a zone is flushed with secondary effluent alone before desorbing. Activated chor or silica gel are used in zones X, Y for adsorbing hydrocarbons or drying respectively.

Abstract: 1,230,430. Making crimped polyester filaments. TEIJIN Ltd. 24 Dec., 1968 [30 Dec., 1967; 8 Out., 1968], No. 61455/68. Heading B5B. Crimped terephthalate polyester filaments are made by wetting terephthalate polyester filaments having a birefringence of 0À001 to 0À012 with a non-solvent for the filaments, drawing the wetted filaments at a draw ratio within the range 1À5 to 6À0 while contacting them with a cylindrical snubbing pin having a radius of curvature within a specified range or having a convex surface portion having radius of curvature within this range, the filaments in the latter case contacting only the convex surface portion in question. The radius of curvature of the pin or of the convex surface portion of the pin is within the range of from 1 mm. to 5À5 (1 + 0À01 V)#D mm. and the pin is maintained at a temperature within the range of from (Tg - 20)‹ C. to (Tg + 25)‹ C. Crimp is developed in the drawn filaments by heating them to a temperature not lower than 100‹ C., e.g. a temperature within the range of about 150‹ to 250‹ C., while allowing them to shrink either freely or under sufficient tension to limit the degree of shrinkage. The symbols V, D, and Tg in the formulµ represent respectively the speed at which the filaments are drawn, the denier of a single filament, and the glass transition temperature of the filaments. The speed at which the filaments are drawn is regarded as the peripheral speed of the draw roll or of the rolls in an assembly of co-operating draw rolls. The term " terephthalate polyester " is defined as a polyester containing at least 85%, preferably at least 90%, by weight of a recurring structural unit having the general formula in which G represents a divalent organic radical containing 2-10 carbon atoms which is bonded to the adjacent oxygen atoms through a saturated carbon atom. The as spun filaments may have a degree of crystallinity not exceeding about 10% and may consist of a substantially amorphous terephthalate polyester. The non-solvent liquids used for wetting the filaments prior to their being drawn may be water, carbon tetrachloride, methanol, ethanol or ethylene glycol. The temperature of the wetting liquid during its application is not critical, but temperatures within the range 0‹ to 60‹ C., particularly room temperature to 40‹ C. have been found very effective. The filaments to be treated by the process of the invention preferably consist of polyethylene terephthalate and preferably have a density not exceeding 1À35. The filaments to be treated may be as-spun undrawn filaments or may be incompletely drawn. The filament denier may be about 1 to 600 and the total denier of the filament bundle may be up to about 10,000. The crimping of the filaments after the drawing step may be carried out on the filaments, on staple fibres formed by cutting up the filaments or on fabrics formed from the filaments or staple fibres.
