Title: Branching transmission with plate clutch for motor vehicle - has auxiliary drive to front wheels with friction and dog clutches sequentially engaged from main drive
Inventor: LEITNER MAX
IPC: B60K17/344
Filed: 1992-01-16
Abstract: The main and auxiliary drive shafts (6, 10) are coupled together by a dog clutch (15) and a low-torque friction clutch (31) working in parallel. The latter is used only in synchronisation of the two shafts at the onset of wheel-slip in order to allow easy and smooth engagement of the dog clutch. Installed within the gear casing (30), the outer clutch plates (33) and ring (34) rotate with the driving gear wheel (5), and the inner plates (32) with the front-wheel drive shaft (10).

Title: Driving of circuit protector with contact bridge magnetically actuated - delaying opening and closing of bridge upon short circuit until contact surfaces have cooled sufficiently to prevent sticking
Inventor: POHL FRITZ DIPL PHYS
IPC: H01H1/54
Filed: 1992-02-20
Abstract: A method of driving a circuit protector whose movable contact bridge (8) has a remote controlled magnetic actuator (28). When a short circuit occurs, the short circuit current produces a magnetic force which opens the contacts (4-7). After the contacts have been opened, their movement is inhibited by an electromagnetic inhibitor (20). Thus, opening and closing of the contact bridge (8) is delayed. The contacts (4-7) are closed again when the contact surfaces have cooled sufficiently to stop them fusing together. ADVANTAGE - A simple system which reliably prevents the fuse contacts from fusing together in the case of short circuiting.

Title: Centrifugal force propulsion for vehicle - has pair of heavy half disks spun on horizontal axis within frame spun synchronously about vertical axis
Inventor: FIEDLER WILHELM
IPC: F03G3/00
Filed: 1992-05-21
Abstract: A vehicle is propelled by the inertia force of an out-of-balance rotating weight. This weight is formed by a pair of parallel half disks attached to one side of a horizontal shaft within a frame. The frame is pivoted about a vertical axis. As the disks are spun by a motor, they impart vertical and horizontal centrifugal force components to the frame and thus the supporting vehicle, both components varying in magnitude and direction with angle of rotation. If the driving motor rotates the frame in synchronism about the vertical axis, there will be a periodically varying horizontal force in a chosen constant direction, though with periodic side forces. ADVANTAGE - Propulsion without using reaction of spent fuel and without direct coupling to wheels of vehicle.

Title: Method and device for analysing glucose in a biological matrix
Inventor: SIMONSEN JAN HENNING
IPC: A61B5/00
Filed: 1993-05-05
Abstract: Method for determining the concentration of glucose in a biological matrix, comprising at least two detection measurements, in each of which light is injected into the biological matrix as primary light, the light is propagated in the biological matrix along a light path and a light intensity emerging as secondary light is measured, and an evaluation step in which the glucose concentration is derived from the measured intensity values of the detection measurements by means of an evaluation algorithm and a calibration. Good analysis accuracy is achieved with simple means in that a first detection measurement is a spatially resolved scattered-light measurement, in which the primary light is injected at a defined injection location into the biological matrix, the intensity of the secondary light emerging from the biological matrix at a defined detection location is measured and the detection location is arranged relative to the injection location such that light multiply scattered at scattering centres in the biological matrix is detected, the intensity of which light is characteristic of the concentration of glucose, and the light path is different in a second detection measurement from that in the first detection measurement.
