Abstract: 591,234. Two-part couplings ; direct connections between conductors. CLARKE, R., SMITH, W. E., and WILSON, G. H. Dec. 19, 1944, No. 25457. [Class 38 (i)] A component for a wiring system comprises a main member b in which conductors a1, a2 are moulded in an insulator which is removed at b1 and d to expose parts c and a1, a2 of the conductors, and a continuation member k, Fig. 11, or a mating member, Fig. 5, in which the insulation is similarly removed to expose parts f1, f2 of the conductors in order that the main and mating members may fit together by superposition with the exposed conductor parts in contact. As shown, the insulator is ovalsectioned and is removed for half its thickness, and in the mating member the conductors f1, ,f2 are exposed in the cross-piece i, and the conductors g1, g2 in the limb j. Thecrosspiece i is secured in the recess d, Fig. 11, by screws r and holes s. The limb j fits the similarly cut-away part of either a continuation member k or another mating member, Fig. 10, comprising cut-away parts and diverging conductors n1, n2 and a through conductor q. Circuit fuses, lamps and switches may also be thus connected.

Title: Improvements in or relating to the combustion chambers of internal combustion engines
IPC: F02B23/08
Filed: 1934-09-05
Abstract: 440,830. Cylinders. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Bohn Aluminum & Brass Corporation; 2512, East Grand Boulevard. Detroit, Michigan, U.S.A.) Sept. 5, 1934, No. 25545. [Class 7 (ii)] In a combustion-chamber 22 extending over the inlet and exhaust valves and a part of the cylinder bore, the distance L, from the sparking-plug points to the edge of the chamber, is directly proportional to the length of stroke and inversely proportional to a constant K which varies with the octane rating of the fuel, and the compression ratio ; if the octane rating is between 60 and 80 and the compression ratio is between 6 to 1 and 7 to 1, K varies between 1À4 and 1À9, according to curves which are shown. If D is the piston displacement, the area of the passage at A, and at B, and that of the part K over-lying the bore are, respectively, within the following limits D/17À5 to 18À5' D/19 to 20' D/12 to 13' and the width at A is between 3 and 4 times the height. The volume over the part K is between 30 and 35 per cent of the capacity of the combustion chamber. The angle J between each valve-head and the roof is 10‹, and the sparking plug is located in the line between the inlet and exhaust valves, and spaced <3>/10 of the distance between them, form the exhaust valve. The wall 25 adjacent the inlet port is substantially straight in the direction of flow into the cylinder. The clearance round the inlet valve when fully open is approximately <1>/10 the diameter of the valve head and the clearance round the exhaust valve is preferably slightly less than this.

Abstract: 478,808. Centrifugal machines. MACHINEFABRIEK REINEVELD N. V. Sept. 24, 1937, No. 25935. Convention date, Sept. 25, 1936. [Class 23] A centrifugal machine has a perforated basket 3 mounted on the shaft 1 of the motor 2 and the basket is enclosed by an impervious basket 5 mounted on the same shaft. The baskets 3, 5 are provided with inwardly projecting lip rings 4, 6 respectively, and an adjustable pipe .13 passes between the rings to withdraw liquid from the space between the baskets. Adjustable scrapers 11, 14 are emplqyed to release the solids from the baskets 3, 5. When the machine is used in the manufacture of maize starch, the liquor from which the insoluble proteins have been removed, is supplied through the pipe 12 to the rapidly revolving basket 3. The liquor is thrown to the wall and the juice passes through to the wall of the basket 5 where it is collected by the pipe 13, the mouth of which is near the wall. After some time, the supply of starch is stopped and the pipe 13 is retracted from the wall. Fresh water is then supplied through the pipe 7 and the channels in the hub to the space between the walls of the baskets 3, 5. The layer of starch on the inner side of the wall of the basket 3 is impregnated with the water which passes inwards through the perforated wall. The supply of water is cut off and the baskets revolve until the soluble proteins are dissolved; the pipe 13 is then moved outwards to collect the liquid and the dry starch is removed from the basket 3 by means of the scraper 11. The machine may also be used for nitrating cotton or for regenerating catalysts.
