Title: Combustion chamber of a rotary piston internal combustion engine
Inventor: KRAIC OTTO
IPC: F02B55/14
Filed: 1965-12-02
Abstract: 1, 094, 957. Rotary-piston internal combustion engines. USTAV PRO VYZKUM MOTOROVYCH VOZIDEL. Dec. 2, 1965, No.51194/65. Heading F1F. In a rotary-piston I. C. engine of the kind comprising a casing having a bi-arcuate trochoidal inner profile within which planetarily rotates a three-sided piston having a combustion chamber formed in each of its sides, each combustion chamber comprises a plurality of cavities with a partition extending to the profile of the piston and wholly or partially separating a pair of adjacent cavities. As shown in Fig. 8, a partition 16 extends transversely across a side 9 of the piston 8 to wholly separate cavities 14, 15 from each other. The partition is shown forward of the midlength of the piston side in the direction of rotation of the piston. It may however be at mid-length of the piston side or after thereof and may include a recess extending partially across its crown with the bottom of the recess sloping downwardly towards either cavity. The purpose of the partition and its recess during the combustion phase of the cycle is to cause sudden turbulence and more rapid burning of the working medium after the partition 16 passes "t.d.c." resulting in higher working pressures, reduced fuel consumption and increased efficiency. In the phase where a piston side is passing between the induction and exhaust ports, the partition reduces the possibility of direct communication between the induction manifold and the exhaust manifold and hence backfiring. In another embodiment, the cavity 15 is circular in plan form and the recess in the partition 16 is tangential thereto. In a further embodiment, there are three cavities with partitions 16 partially separating adjacent cavities and staggered with respect to each other. In this embodiment, two ignition devices or fuel-injectors may be fitted, being located opposite to the leading and centre cavities when the piston is in its "t.d.c." position. The partition 16 may also be disposed longitudinally with respect to the side of the piston or diagonally thereto with the induction and exhaust ports through the peripheral surface of the casing arranged so that they are on either side of the partition. This arrangement allows the induction and exhaust ports to be more effectively separated from each other.

The products, with halogeno-hydrins, give 1-hydroxy - alkyl - 2 - R - benzimidazoles which may be converted to reactive esters, e.g. 1-haloalkyl -2-R-benzimidazoles.  N - (4-Chlorobenzyl) - 2 - nitro - aniline is prepared from 2-chloro-nitrobenzene and 4-chloro - benzylamine.

Abstract: 521,232. Safety cut-off valves. HORSTMAN, F. O., and HORSTMAN GEAR CO., LTD. Nov. 14, 1938, No. 33090. [Class 135] A safety cut-off device for a gas burner comprises main and pilot burner supply valves, the pilot valve being opened manually while the main valve is opened and both valves closed by thermo-responsive means subject to the heat of the pilot flame. The main valve 2 which is balanced by a diaphragm 11 is coupled by a spindle to the free limb of a bimetallic U piece 12 subject to the heat of the pilot flame 14. The burner 14 is supplied with gas through a passage 15 and a pipe 13 under the control of a valve 6 housed in a chamber formed in a detachable coyer 4. The valve 6 has an actuating spindle 7 provided with a manipulating knob and has a second spindle 9 provided with a circumferential groove adapted to co-operate with spring fingers 10 secured to a flange on the main valve spindle. When the knob is pulled outwardly to open the pilot valve the spindle 9 slides through the spring fingers, as the bimetallic strip heats up the fingers slide into engagement with the groove or beyond so that when the strip cools both valves are moved on to their seats. The thermal means may also be heated by the main burner so that closing of the main valve will not take place unless both main and pilot burners are out.

Abstract: 1,269,334. Determining co-efficients of friction. M. S. RHODES and G. W. THORN. April 2, 1970 [Jan. 5, 1969], No. 52271/68. Heading G1S. A device for measuring co-efficients of friction comprises a mobile structure with two running wheels 7, 8 respectively fixed and rotatable upon a common axle 6, the wheels being of different diameters, means providing a torque to resist relative angular movement of the wheels, and means responsive to the magnitude of the torque which when slippage of the rotatable wheel occurs, gives a measure of the co-efficient of frction between the perphery of the wheel and the surface over which it is moving. As described the torque is provided by two spring-loaded plungers 21 carrying brake pads 20 acting on a brake disc 19 on wheel 8. Axial movement of the rotatable wheel which is in screwthreaded engagement with the axle compresses springs 25 applying increasing braking torque to disc 19. The movement of the plungers is monitored by a potentiometer 31 in series with an ammeter calibrated in units of co-efficient of friction. Alternatively the brake pads are mounted on hydraulic rams; the increasing hydraulic pressure is monitored to indicate co-efficient of friction. Alternatively a torsion spring is anchored to the frame 12 of the device and provided with a means for measuring the torque, in this case the bearing between the rotatable wheel and the axle is plain.
