Patent DE-4244854-A1 (DE)
Title: Telefax or colour television image coding system
Inventor: DIRR JOSEF DIPL ING
IPC: H04N7/24
Filed: 1992-12-23
Abstract: The coding system shortens the transmission time for black and white digital or numeric longitudinal coding, by using the same codewords for both black and white and for different numbers or characters, with the input sequence of black and white used as the discrimination criteria. When several successive white lines are coded, the transmission time is reduced further by providing the coded number of white lines before or after the white line codeword. During gray coding the gray stages or binary codewords are sub-divided, with deliberate redundancy where characters occur successively, with subsequent transmission in the same manner as the white lines. The transmission time is reduced for colour image transmission by code multiplexing, with the PAM coded information DC biased. The sum alternating current thus varies in phase by up to 90 degrees.

Title: Equipment for detecting load-induced stresses in roller bearings
Inventor: GRELL KARL-LUDWIG
IPC: G01L5/00
Filed: 1993-02-17
Abstract: The invention relates to an equipment for detecting load-induced stresses in roller bearings (2), which stresses are caused by rolling processes of roller bodies (6). The equipment is distinguished in that at least one axial bore (7) is arranged in an inner ring (4) or outer ring (5) and leads into the loading zone, this bore (7) is filled with a hydraulic fluid (11), is closed at its open end with a diaphragm (8), on which a measuring sensor (9) is arranged which is connected to an evaluation device (10). The elastic deformations caused by the rolling processes of the roller bodies (6) lead to a reduction in volume of the axial bore (7) filled with a hydraulic fluid (11). This reduction in volume effects an increase in the hydrostatic pressure and represents the local loadings of the bearing (2), corresponding to the number of the axial bores (7) present. <IMAGE>

Title: Process and apparatus for treating organically polluted, finely divided bulk materials
Inventor: WEYLAND WOLFGANG
IPC: F23G5/00
Filed: 1993-06-25
Abstract: Before certain organically polluted bulk materials, obtained for example as filter or foundry dusts, can be recycled or landfilled they have to be subjected to a treatment to incinerate their organic component.

Title: Arrangement for mounting the propeller shaft of elastically installed propulsion systems
Inventor: SCHAEFER WILHELM F DR ING
IPC: F16C23/04
Filed: 1993-08-07
Abstract: In propulsion systems, the elastically installed propulsion component is coupled to the rigidly founded thrust bearing via a displacement coupling of appropriate overall length. The novel arrangement is to permit large angular displacements of the shaft, in which case the reaction forces which occur are to be kept small, and is to have a short overall length. As a solution, it is proposed that the propeller shaft (11) be passed through the thrust bearing (7) in such a way that it can perform an angular motion and that it be connected on the output side behind the thrust bearing (7) to a rotatable joint (8) and on the drive side in front of the thrust bearing (7) to a joint (6) which can move axially and in an angular manner. The joint (8) is designed as a spiral-toothed dog clutch and the joint (6) is designed as an elastic shaft coupling. This arrangement enables very large radial and axial displacements to be absorbed and is used in particular in marine propulsion systems. Marine propulsion systems of this type are substantially less expensive to produce due to the short overall length. <IMAGE>

Patent DE-4333849-A1 (DE)
Title: Two-chamber cutting system for comminuting mills for foamed material
Inventor: JUNGKUNZ MARIA
IPC: B29B13/10
Filed: 1993-09-04
Abstract: The invention relates to a cutting system which particularly economically comminutes foamy plastics/rubber, in one operation, on a machine. The two-chamber system operates vertically. Upper, oblique/V-cutters, the drive shaft, flywheel and internal cutter form a unit. The two-chamber system is formed by a horizontally installed separating grate/partition. The material to be cut passes through the feeding funnel into the prechamber, is grasped there by the oblique/V-cutters and pre-comminuted to a size which fits through the separating grid lying therebeneath and in this manner is drawn into the lower cutting chamber. Here, the material is cut by the main cutter to the size which passes through the hole size of the screening plates revolving through 360 DEG . The two-chamber cutting system prevents the cut material from being compressed in the lower cutting region, which would necessitate an increased outlay on energy. All of the conventional cutting systems have been analysed. This invention provides a system of superior cutting geometry. Extensive safety devices are, of course, also installed.

Patent DE-4344369-A1 (DE)
Title: Limitation of power supplied to vehicle drive to control energy consumption
Inventor: BUCK MICHAEL DIPL ING
IPC: B60L11/18
Filed: 1993-12-24
Abstract: The power supplied to the drive is controlled by a computer (1).  The computer accepts journey data (2) entered by the driver, and determines the distance to be travelled.  The energy carried by the vehicle in its battery or fuel tank is monitored continuously during the journey.  This and the distance remaining are used to set the consumption allowed for the remainder of the journey. This set consumption level is used to control the limitation of power delivered to the drive.  As the set consumption level becomes smaller the power is more strongly limited.  The relationship is determined from a characteristic curve.  The characteristic curve is modified by measured performance of the vehicle.
