Title: Improvements in or relating to variable compression engines
IPC: F02B75/04
Filed: 1936-05-22
Abstract: 480,768. Driving - gear. DE MONGE, L. May 22, 1936, No. 14565. Void. Convention date, May 22, 1935. [Class 7 (ii)] To vary the compression ratio either the main piston itself or the upper portion of a two part piston is adjusted relatively to the cylinder head. When adjusting the main piston through the medium of a two-part screwed connecting rod a rotary motion is imparted to the piston by teeth that engage slots provided along the length of a piston skirt. When using a two-part piston, the rod of the upper part has a screw connection with the lower part and rotary movement is imparted to the rod by a toothed rack which engages teeth cut along the length of the rod. In the construction shown in Fig. 4, the piston 6 is rotated relatively to its support 15 by toothed gearing 17, 18, the wheel 18 being mounted on a flexibly-actuated shaft 19 connected by gearing to an operating shaft 21. The mechanism for actuating the shaft 21 from the engine cam shaft is shown in Fig. 5. It comprises a clutch part 24 carried by the cam shaft and engaged by one or other of two cone-shaped clutch parts 26 carried by a screwthreaded shaft 30 in engagement with a toothed sector 29. The sector is controlled by a leverarm 23 and rotary movement of the shaft 30 is transmitted to the shaft 21 by splines and toothed gearing 28. An engine using the various means for varying the compression ratio may be charged by a blower driven electrically or from the crank shaft.

Title: Improvements in drive chains
IPC: F16G13/04
Filed: 1931-05-19
Abstract: 383,295. Driving chains. BURGESS, A. F., 10, New Court, Lincoln's Inn, London. - (Link-Belt Co. ; 910, S. Michigan Avenue, Chicago, U.S.A.) May 19, 1931, No. 14765. [Class 24.] In power transmission chains, thrash is prevented by providing two articulating centres on the joint pins spaced apart in a direction substantially normal to the line of tension. As shown in Fig. 7, the pivot pin is of elongated section having two semi-cylindrical end portions with centres a, b, and connected by two tangential plane surfaces meeting at z. The apertures in the links are of corresponding shape and of a size to provide a limited amount of rocking movement between the links and pins. Normally the line of pull on the chain is perpendicular to the line a, b, the transmission being effected through the flat bearing surfaces. Lateral deviation of the links causes rolling of the links on the pins about the centres a or b and introduces forces tending to resist the deviation. Modifications are described including liners for the link apertures, and also constructions in which the pins are fixed to alternate links. The invention is described as applied to chains of the " silent type, but may be also applied to roller or block chains.

Abstract: 119,707. Carson, J. H., and Wade, G. H. Oct. 12, 1917. Steering and balancing.-The gyroscopic action of an aeroplane propeller is utilized to effect adjustment of the propeller axis in any direction, a couple being applied to the propeller so as to cause it to precess into the desired direction. The elevator or aileron may be adjusted simultaneously with the propeller. Fig. 1 shows a propeller E rotatably mounted on a ring D which may be adjusted in any direction on a fixed part-spherical member C. The propeller shaft F is provided with a universal joint O, and the forces applied to the ring D are conveyed to the propeller by means of a rib-and-groove connexion D<2>, E<2>. Rods M<1> - - M<4> connected to the ring D are attached to cables K<1> - - K<4> leading to the control lever H. The rods M<1> - - M<4> are passed through radial slots in brackets A<1>, so as to prevent rotation of the ring D. Fore-and-aft thrusts applied to the control lever H are transmitted to the ring D by means of an extension H<2> and the cables K<3>, K<4>, which thereby apply a couple to the propeller causing it to precess about a transverse axis. Similarly, lateral pressure applied to the lever H is transmitted by means of a yoke L and the cables K<1>, K<2> to cause the propeller to precess about a, vertical axis. Connexions W<1> - - W<4> may lead to the elevators and ailerons. In modifications, the engine is mounted so as to be adjusted with the propeller. Specification 12256/09 is referred to.

Abstract: 612,356. Automatic temperature-control systems. CHANDLER, E. A., and MOLINS MACHINE CO., Ltd. May 20, 1946, No. 15208. [Class 38 (iv)] In an automatic temperature-control system a thermostat is switched into a relay circuit at timed intervals for a very brief period to control the heating elements of a packing machine such as described in Specification 593,866, [Group XVII]. A thermometer 2 has platinum contacts 3, 4 connected in series with a battery 5, a relay 10 and contacts 7, 8 of a switch which is operated periodically by a cam 21. A parallel circuit has contacts 11 and 12 operated by the cam 21 and contacts 13, 14 which are closed by the relay. Normally closed relay contacts 16, 17 control the heater 19. When the temperature is high, a column of mercury bridges contacts 3, 4 so that when contacts 7, 8 are closed by the cam the relay is energized, closing contacts 13, 14 and opening contacts 16, 17 to interrupt the heater circuit. Continued rotation of the cam opens and closes contacts 11, 12 and then opens contacts 7, 8, but the relay coil remains energized as contacts 13, 14 are closed. The relay will remain closed on the next cycle of operation if the temperature is still high, but if the temperature has fallen there is no circuit between contacts 3, 4 so that as soon as the cam opens contacts 11, 12 the relay is deenergized, contacts 13, 14 open and contacts 16, 17 close to restore the heater circuit. In a modification, Fig. 2 (not shown), the contacts 7, 8 and 11, 12 are actuated by a relay energized by the periodic discharging of a condenser through a neon tube in series with the coil of this second relay.
