Title: Disc brakes
IPC: F16D65/46
Filed: 1981-05-01
Abstract: A housing (2) for a disc brake incorporates an expander mechanism (6) whereof plate (9) is formed by separate inner and outer concentric rings (10, 11); in normal braking, an annular piston (16) works in an annular hydraulic cylinder (17) to urge one ring (e.g. 10) into engagement with a friction disc (5). The brake can also be applied mechanically by moving the other ring (e.g. 11) angularly with respect to the plate (8) causing balls (14) to ride out of inclined recesses (15) in adjacent faces of the ring (11) and plate (8). In this manner of operation a servo effect is obtained and helical movement of the annular piston (16) is eliminated. As shown, piston (16) also moves plate (8) of the expander mechanism (16) to act on a single disc (5) - ring (10) acts on a disc stack; plate (8) could alternatively be fast with housing (2). Each of the discs (5) in the stack has concentric rings (26, 27) of lining material carried on a plate (25) - in Fig. 4 the discs are formed from relatively axially movable rings. In Fig. 1 mechanical operation is by a transmission member (23) and an additional hydraulic piston-cylinder assembly (20) is provided. Modifications of such operation are disclosed (see eg Fig. 5). <IMAGE>

Patent GB-2135423-A (GB)
Title: Piston and cylinder configuration
Inventor: SWALES ALEXANDER WALTER
IPC: F02G1/043
Filed: 1983-02-12
Abstract: A cup-shaped piston with apertures at the bottom of the cup fits around a projecting cylinder head. Both piston and cylinder head fit into a cylinder which has inlet and exhaust apertures. In its IC engine application, the induction of air or an air/fuel mixture takes place at one end of the cup whilst the exhaust of the combustion products takes place at the other. The whole length of the cylinder formed by the cup is thus swept by the incoming charge ensuring maximum scavenging efficiency. Induction and exhaust are controlled by the position of the piston itself and additional valves are not required thus maximising mechanical efficiency. The configuration is applicable to engines based on modified Stirling or Ericsson cycles and to fluid pumps. <IMAGE>

Title: Electronic speed measurement of a reciprocating internal-combustion engine
Inventor: BUTSCHER FRANZ
IPC: F02B75/02
Filed: 1985-02-05
Abstract: The actual speed of rotation of a reciprocating internal-combustion engine is determined from a number of instantaneous speed measurements which are each carried out electronically over equal fractions of one crankshaft revolution. As shown, the passage of each tooth on a gearwheel 11 past a sensor 13 produce a pulse which is used to gate a counter 16 receiving pubs from a generator 20. The resulting counts are fed in and stepped through an array 23 of memory locations dimensioned (e.g. twice the number of gear wheel teeth for a four stroke engine) so that after each instantaneous speed measurement the arithmetic mean can be formed from the results of all the instantaneous speed measurements of the last crankshaft revolution corresponding to one working cycle of the reciprocating internal-combustion engine. This results in a very accurate value for the actual speed of rotation. Moreover, deviations from a prevailing speed level are detected immediately. <IMAGE>
