Patent DE-4228901-A1 (DE)
Title: Variable control for IC engine valves - has axially slidable camshaft with conical cams and includes tilting lever with rotary parts.
Inventor: KACPRZAK ZBIGNIEW
IPC: F01L13/00
Filed: 1992-08-29
Abstract: The control has a driven part (5), transmitting the drive by pins (4) to the camshaft (11). At increased speed, the centrifugal force overcomes the weights (6), held by springs (7), for sliding the camshaft in plain bearings (1), using sliders (2), in the dissection of the control part (3). The camshaft connected pins penetrate into the control part for bringing the camshaft into contact with the central part. On reduced speed, the weights are compressed by the springs until the sliders abut the control part. The conical cams (9) slide w.r.t. the tilting levers (8) for the change of the valve opening. USE/ADVANTAGE - Variable control for IC engine valves operates without need for a hydraulic system.

Title: Recovering valuable material from waste solid rocket fuel - by removing fuel from rocket housing by wet decomposition process followed by high-velocity underwater maceration process
Inventor: SPAS STANLEY E
IPC: C22B21/00
Filed: 1992-09-10
Abstract: Waste material from solid propellant fuel for rockets is processed in order to recover valuable aluminium particles and oxidation medium, in a re-usable form and the residual solid matter is incinerated (64) in an environmentally friendly manner. The fuel is removed from the rocket housing by a wet decomposition process and then has an oxidation medium content of 40 to 50 percent by weight. The oxidation medium content is then reduced to 35 to 45 percent by weight by means of a high velocity underwater maceration process.

Title: Process for controlling the translatory movement sequence of a trolley with a load which is capable of swinging
Inventor: MATTHIAS KARL DR ING
IPC: B66C13/06
Filed: 1993-11-10
Abstract: The invention relates to a process for controlling the translatory movement of a trolley with a load which is capable of swinging, on gantry cranes and portal cranes and on slewing cranes with trolley jibs. The mass of the trolley, the mass of the load, the length of the swinging load, the initial swinging angle and the initial swinging angle speed are used to determine a force F11 with an associated time T11, which force acts on the trolley before the accelerating phase which is caused by F12 (or F3). The force eliminates swinging movements of the load which are present at the beginning of the trolley travel or arise during said travel. The advantage of the process consists in the fact that the load does not have to stop swinging before the trolley begins its travel, and the inactive time of the trolley is thus shortened. <IMAGE>

Title: Double-cam joint with internal length adaptation for 90 DEG homokinetic joints with radius gears
Inventor: BRAUN JUERGEN
IPC: F16H1/00
Filed: 1994-03-25
Abstract: A homokinetic joint with a bend angle of up to 90 DEG  is held in interengagement by a sprung inner joint so as resiliently to compensate the change in the centre of rotation of the inner joint during bending. The inner joint must here have the ability to bend in two planes. Due to the sprung inner joint, the homokinetic joint attempts to assume its extended position since, in all positions, it is acted upon by the spring load. In order to hold together a homokinetic joint with a bend angle of up to 90 DEG  by means of an inner joint without the homokinetic joint having a tendency to assume its extended position, a double-cam joint is used. By virtue of spiders mounted in guides, this double-cam joint can compensate the required change in the centre of rotation. <IMAGE>
