Patent DE-3832950-A1 (DE)
Title: Variable multi-stage hysteresis mechanism
Inventor: MAKI NAOYUKI
IPC: F16F15/123
Filed: 1988-09-28
Abstract: A description is given of a device which absorbs torque changes stemming from an engine. The device has a variable multi-stage hysteresis mechanism which is characterised in that a first element is rotatable together with an input element and a second element is rotatable together with an output element, the second element being pressed against the first element and sliding on the latter. The first or second element comprises a convex portion which is pressed against the other element and slides on the latter. This makes it possible to vary the frictional force in stages.

Patent DE-3839716-A1 (DE)
Inventor: BRAEMERT PETER
IPC: B61D17/22
Filed: 1988-11-24
Abstract: The invention relates to the front part of a railway car, having an intercommunicating gangway, which is variable in length in the longitudinal direction of the car, in the area between two lateral buffers, sprung in the longitudinal direction of the car. At least under certain operating conditions, the intercommunicating gangway lies with its associated parts below a horizontal plane, over which the buffer heads protrude upwards. When their buffer springs are under normal stress, the buffer heads lie in a vertical transverse plane, in which front end parts of the intercommunicating gangway lie. Furthermore, the intercommunicating gangways of two cars to be connected to each other are preferably held in contact without solid connection by springs acting in the longitudinal direction and, finally, the gangway treadplates of this intercommunicating gangway are preferably adjustable in the longitudinal direction independently of the protection of the gangway. The invention is characterised in that means are provided by which the buffer heads and the said front end parts of the gangway treadplate can be kept essentially in a common perpendicular plane transverse to the vehicle even when the buffer plates change their position due to changed stressing of the buffer springs.

Patent DE-3842924-A1 (DE)
Title: Stretcher
Inventor: DOSCH GUENTHER
IPC: A61G1/00
Filed: 1988-12-21
Abstract: In conventional stretchers, the fabric is unreleasably fixed on the frame comprising support bars and transverse bars, so that an individual transported on the stretcher has to be transferred from the fabric to a medical treatment table, a couch or the like. The physical contact required by this transfer may lead to severe pain and/or additional injury to the ill or injured person. In order to permit gentler transfer of a pain-sensitive and/or injured patient, the fabric of the stretcher is releasably fixed to the frame, so that the patient can be placed, together with the fabric which remains in place, on the medical treatment table, couch or the like. For subsequent further transport the fabric can again be fixed to the frame. Possible fabrics are all suitable underlays, for example a sheet, a blanket or a tear-resistant film.
