Patent DE-3213893-A1 (DE)
Title: Device for connecting two parts which are located at a variable distance
Inventor: KRESS HERMANN
IPC: F16K27/00
Filed: 1982-04-15
Abstract: A device is described by means of which large different distances between parts which are to be connected to one another can be bridged over in a force-fitting manner, the transmitted force being kept within tight limits. To this end, it is constructed from at least two supporting rings, which can be pushed one inside the other like a telescope, of which at least one has weak-point projections on one of its envelope surfaces. The end side of another supporting ring rests against said projections. A spring device is provided which is compressed when the parts which are to be connected to one another approach one another. If the compression force exceeds a specific value, the weak-point projection or projections is or are sheared off. The rigid frame, consisting of the supporting rings, is shortened by a specific amount while the spring device is relieved of tension. By means of a plurality of groups of weak-point projections, which are located at axially different positions on one or more supporting rings, the shortening of the rigid frame consisting of the supporting rings and the relief of tension in the spring device, associated therewith, can be repeated many times. A special field of application is in the design as a sealing device, which is used especially in the assembly of sanitary shut-off valve upper parts in valve housings in which the retention space is of different depth. <IMAGE>

Title: Method for establishing the ratio of live to dead cells in yeast suspensions
Inventor: BOGDANOV KIRILL MICHAILOVIC
IPC: G06V10/20
Filed: 1982-05-25
Abstract: The method is based on using a scanning microscope for scanning and photometry of a monolayer preparation of the yeast suspension and generating a digital matrix of the image, in which the images of the contour lines of the cells are discriminated on the basis of the brightness threshold between background and the image of the cells. After this for each cell a histogram of the brightness amplitudes of its image is constructed and the dispersion and the asymmetry of the histogram are calculated, after which the cells to be investigated are identified as live or dead cells by comparing the calculated parameters with predetermined threshold values.

Patent DE-3231175-A1 (DE)
Title: Brake disc for disc brake
Inventor: WEISBROD HELMUT
IPC: F16D65/00
Filed: 1982-08-21
Abstract: The invention starts from brake discs for disc brakes, in particular for motor vehicles, with a hub (3), which can be mounted on a shaft to be braked, and with a friction disc (2), which is connected to the hub (3) and on which friction linings can be brought to bear. To avoid distortions of the friction disc (2) during the braking operation as a result of greater heating of the central region of the friction disc (2), the invention proposes to make the expansion due to heating during the braking operation at least as great at the outer edge of the friction disc (2) as in the remainder of the friction disc (2). The outer region of the friction disc (2), which is heated more strongly during the braking operation, exerts a radial tensile force on the remaining material of the friction disc (2), tautening the friction disc (2) and excluding distortions. <IMAGE>

Patent DE-3317218-A1 (DE)
Title: Gear shift device
Inventor: OETTING HERMANN DR ING
IPC: F02B1/04
Filed: 1983-05-11
Abstract: A device for the automatic shifting of a multiple-gear change-speed gear (2) assigned to a vehicle, especially a passenger vehicle, has a control unit (8) determining the gears to be engaged as a function of the speed of travel, the position of the accelerator pedal (11) and the position of an arbitrarily adjustable drive range selector lever (9). In order to provide the facility for improved utilisation of the engine braking effect in a gear shift device of this type, for example when operating in mountainous terrain, it is proposed that in at least one shift position of the drive range selector lever the control unit be designed to automatically return the change-speed gear (2) to gears producing maximum engine braking effect if the accelerator pedal (11) is not being depressed. In so doing the intention in each case is to change down to those gears in which, for the current speeds, the engine revolutions lie in the maximum admissible speed range, especially in the range between the maximum admissible speed and approximately 2/3 of this value. <IMAGE>

Title: Road train with a steering facility for the trailer vehicle
Inventor: BAUDENBACHER M
IPC: B62D13/02
Filed: 1983-08-04
Abstract: The invention relates to a road train with a steering facility for the trailer vehicle, having a rigid forked drawbar which is coupled to the towing vehicle, the trailer vehicle having a live ring transmission by means of which the steering of the trailer vehicle is influenced when going round bends. So that the steering fork can be completely dispensed with in a road train of this kind, there is provision according to the invention for the forked drawbar to be guided in a telescopic manner in the longitudinal direction with respect to the live ring frame and for a central push rod to be arranged between the forked drawbar and the bogie, the said push rod being connected to a live ring transmission. By means of this live ring transmission, when going round a bend the push rod displaces the forked drawbar with respect to the bogie, the live ring transmission being arranged behind the axle in the direction of travel. For this purpose, the live ring transmission can have a sprocket wheel transmission, downstream of which a crank mechanism is connected. In this way, coupling only has to take place with the forked drawbar, as is generally customary. In this way, any towing vehicle can be coupled to the trailer vehicle of this kind.
