Title: Rotary piston engine with oscillating inserts in rotor - configured as levers to maximise efficiency of energy conversion
Inventor: DICK WILHELM
IPC: F01C1/44
Filed: 1975-08-29
Abstract: The rotary piston engine comprises a casing (1) fitting closely around a circular rotor (2) fixed to a concentric output shaft. In the face away from this shaft, the rotor has a recess (3) into which projects a cam (21), fixed to the casing, against which bear rollers (22, 22a) each supporting one end of oscillating pistons (4, 4a) pivoted axially near the other end (5). These pistons are a close fit in the rotor recess and against the casing face so that the cyclic variation of the space between piston and casing with rotor rotation can be used for pumping or for an IC cycle. The lever configuration maximises energy conversion efficiency. Instead of the cam (21) a cranked output shaft going through the rotor with connecting rods to the pistons can be used. Reversing gearing must then be fitted however, between this shaft and the rotor, and a multi-row arrangement is possible.

Title: Aircraft control surface actuating gear - has quadrilateral linkage with idler replaced by three link unit with T-link coupled to bell-crank
Inventor: ZIMMER HERBERT DIPL ING
IPC: B64C13/28
Filed: 1976-11-09
Abstract: The linkage for actuating aircraft aerodynamic control surfaces, esp. ailerons, has a link quadrilateral converting linear movement of the input rod (25) into rotation of the bracket (24) carrying the aileron mounted on outriggers (5) from the wing. The normal idler link in the quadrilateral is replaced by a 3-link unit (30, 45, 31) with a T-link in the middle connected to a fixed pivot (36) bell crank (35). A linear input (43) to the bell crank thus varies effective link length, permitting aileron angling independent of normal operating mechanism. Ailerons can thus be used for rapid lift variation.
Patent DE-2657719-A1 (DE)
Inventor: FIEDLER JOERG
IPC: B61L3/22
Filed: 1976-12-20
Abstract: So that railway vehicles can travel safely on a network of tracks, it is necessary to transmit information, in particular control point data, relating to the respective section of track ahead from one central control unit to each vehicle. When a vehicle travels into a points area (GT2 or GT5), different travel paths result depending on the position of the points. However, an evaluation of the positions of the points in the central control system for the purpose of determining the travel instructions inside the points area (GT2 or GT5) can be dispensed with in that in each case one signal (SL2 or SL7) permits entry into the points area (GT2 or GT5) only at a restricted travelling speed, and in that a report device in the central control unit triggers a special instruction when the vehicle travels in the points area (GT2 or GT5), which instruction actuates vehicle-side switching means so that the vehicle maintains the restricted travelling speed until it travels into the subsequent track section (GT4). <IMAGE>
