Patent DE-19645500-A1 (DE)
Title: Hermetically-sealed thermodynamic positive-displacement pump
Inventor: KLOPP RAINER L M DIPL ING
IPC: F04B19/24
Filed: 1996-11-05
Abstract: The medium in the working chamber (9) is enclosed by a diaphragm (10), the chamber in turn being contained in a pump chamber (4) closed apart from outlet and inlet ports (6,7). A heater for the working medium increases its volume, thus displacing the medium in the pump chamber. Liquid with a high coefficient of heat-expansion can be used as the working medium, so as to be effective against back pressure also. Heating can be by heat-transfer through the chamber wall, a heat-exchanger, or electric heating wire. The timing and amount of heating can be variable, and after displacement heat can be extracted and transferred to another point of use.

Title: Control system for steplessly-adjustable automotive transmission
Inventor: NOBUMOTO HIDETOSHI
IPC: F16H61/16
Filed: 1996-11-07
Abstract: The system (CVT) regulates the ratio dependent on performance characteristics and vehicle operating conditions. It monitors the operating conditions, and has a control system regulating the ratio in stages, altering the engine speed by an alternate gradual increase and rapid reduction. The system also increases engine speed linearly with rising vehicle speed, with stepless ratio alteration. Unstable operating conditions are detected, and the range within which alteration in stages takes place is correspondingly reduced, or cancelled altogether.

Title: Self-contained emergency braking system
Inventor: LELL PETER DIPL ING DR
IPC: B66B15/00
Filed: 1997-05-20
Abstract: The safety of hoists and cranes is ensured by arresting the movement of the load cable automatically. This uses a brake activated by the ignition of an explosive cartridge in the event of an emergency resulting in excessive cable speed. A hoist cable (35) has brake blocks (38,39) around it which may be activated by the ignition of a small explosive charge and latching spring arrangement (41,42) by an igniter (40). A pair of dynamo generators (49,54) running on rails (48,56) and connected to the lifted body (33) provide the energy for ignition when they run at excessive speed due to a failure. A second cylinder system locks on the rail (56) in a similar manner with a braking system (82,83).

Patent DE-19852049-A1 (DE)
Inventor: SAHM DETLEF DIETER
IPC: B23Q3/155
Filed: 1998-11-11
Abstract: The invention relates to a tool head with a spindle bearing arrangement. The bearings (9, 10) of said arrangement rest with one of their bearing shells on a driven spindle (2) with a tool holding fixture (1). With their other bearing shell they interact with a housing (8) in such a manner that in at least one part (10) of the bearings (9, 10) the respective other bearing shell interacts with a sliding piece (11) which is slideable along the housing (8) in the one sliding direction and which locks the spindle (2) with the housing (8) in a locking position. In the other sliding direction, said sliding piece releases the spindle in a release position. The invention provides a universally useful tool head by the following configuration: The respective other bearing shell of the one part (10) of the bearings (9, 10) is at least partially enclosed by the sliding piece (11). Said sliding piece (11) is forced into the locking position with a predetermined contact force by a drive device. The sliding piece closely fits the housing (8) when the lock is released. Said tool head can be used for both milling and turning on a lathe. The tool head provides also a means for simultaneously relieving the spindle bearing arrangement when the tool is operated in a nonrotative mode.
