Title: Drive arrangement for motor vehicles with at least two drivable axles
Inventor: FRIEDRICH KARL ING
IPC: B60K17/08
Filed: 1984-09-26
Abstract: In a drive arrangement for motor vehicles, at least two drivable vehicle axles (6) and a drive assembly are provided, which drive assembly comprises the engine (1), the drive clutch (2) and the gearbox (3). The shafts of this drive assembly run transversely to the direction of travel. The output shaft (4) of the gearbox (3) drives the wheels of the one vehicle axle (6) by way of a pair of spur gears (7, 8) with helical toothing, whereas the wheels of the other vehicle axle are driven by way of a propshaft (14). In order to reduce the technical cost, and to obtain a more compact construction, improved efficiency and a weight reduction, a spiral-toothed gear wheel (11), from which the drive of the propshaft (14) is derived, meshes with the driven gear (8) of the helically toothed pair of spur gears (7, 8) or with a further, likewise helically toothed, spur gear (10) drive-connected to this driven gear (8). At the same time it is also possible to insert a differential gear (15) between the driven gear (8) of the pair of spur gears (7, 8) and the further spur gear (10). <IMAGE>

Title: Centrifugal crushing device
Inventor: TERRENZIO GABRIEL M
IPC: B02C13/18
Filed: 1984-11-17
Abstract: A centrifugal stone crusher is provided with a cylindrical housing (10). A running wheel (30) is attached inside the housing concentrically with respect to the axle of the housing for rotation about the axle. Stones are fed through a feed arrangement (19) which feeds the stones into the running wheel (3), as a result of which the stones are thrown out of the rotating running wheel through a plurality of openings. The stones then strike against a crushing surface (50) for comminution or crushing. Inside the running wheel, some of the incoming stones are intercepted as an accumulation and the openings have upper and lower edges at a distance from the upper and lower plates of the running wheel, as a result of which protection is provided for the running wheel against wear. Anvils (50) which form the crushing surface can be at such a distance that the comminuting device can be converted to a type in which a stone bed is used as crushing surface. In addition, the feed pipe (18) can be adjusted downwards forming part of the feed arrangement (19) in order to compensate wear along the floor edge of the pipe. <IMAGE>

Patent DE-3504329-A1 (DE)
Title: Differential pressure measuring instrument
Inventor: HECK BERND ING GRAD
IPC: G01L13/02
Filed: 1985-02-08
Abstract: The differential pressure measuring instrument has a liquid-filled single-chamber differential pressure sensor (1) with two measuring capacitors (C1 and C2) whose capacitances vary in the opposite sense with a differential pressure to be measured and in the same sense with temperature. Via one measuring circuit (6, 7) each for forming reciprocals from the capacitance values, the measuring capacitors (C1 and C2) are connected, on the one hand, to a subtracting element (8) for forming measured pressure values from the difference and, on the other hand, to a summer (9) for forming measured temperature values from the sum of the reciprocal capacitance values. In order to measure relatively large differential pressures accurately irrespective of temperature fluctuations in the single-chamber differential pressure sensor (1), the measured temperature values are corrected in a first active filter (14, 15, 16) to such an extent that a second active filter (l0, 11, 12) generates from the measured pressure values and an error-free temperature signal delivered by the first active filter (14, 15, 16) generates a pressure signal whose values correspond precisely to the differential pressure  DELTA P acting on the single-chamber differential pressure sensor and are displayed in a display device (13). <IMAGE>

Title: Compressed-air thread-splicing apparatus
Inventor: KNORS HERBERT
IPC: B65H69/06
Filed: 1985-05-22
Abstract: For better adaptation to the respective yarn twist, the thread-holder tubes (46, 47) are inserted in housing orifices (13, 14) so as to be capable of being changed over into two operating positions. At the same time, the direction of the tangential orifice (52) goes from the distributor space (36, 37), in the one operating position, to a region of the channel (50, 51) receiving the thread end (34', 35') located on the right of the longitudinal axis and, in the other operating position, to an area of the channel (50, 51) receiving the thread end (34', 35') located on the left of the longitudinal axis. A holding-air flow rotating to the right in one case and a holding-air flow rotated to the left in the other case is obtained in the channel (50, 51), this resulting from the injection air flowing through the tangential orifice (52) and from the ambient air carried along with it. <IMAGE>

Title: Grinding machine with a control device for the camber grinding of cutters, in particular mincing-machine cutters
Inventor: KNECHT MANFRED
IPC: B24B3/40
Filed: 1986-05-24
Abstract: For the camber grinding of the cutting edge of a mincing-machine cutter, the latter is guided in a known manner on a rotating grinding wheel using controlled movement components such that rolling movements of the cutting edge result, producing, in a plurality of grinding zones merging into one another, the contour of the camber profile with an optimum cutting angle. The predeterminable grinding angles of the zones are transferred to a working element of the grinding machine as a function of the adjustable stroke lengths delivered by a servomotor, as a result of which the grinding movements of the workpiece are correspondingly guided. To reduce the previous time and handling expenditure and further increase the operating precision, it is proposed to make control operations in some cases proceeding semi-automatically fully automatic by providing an electronic, programmable controller of the feed coordinates for the workpiece, which can be integrated into the control device. The drawing shows: 1 - mincing-machine cutter; 6-10 - control elements; 11 - servomotor; 12 - controlled electronics; 13 - grindstone; B - camber profile. <IMAGE>
