IPC: B62D11/10
Filed: 1983-06-06
Abstract: On each side of the vehicle a hydrostatic drive (7, 13; 8, 14) is arranged, the primary part (17, 18) of which is driven by an engine (3) via toothed gearing (4, 5, 6). Actuation elements (17, 18) serve to change gear and steer the vehicle, the said elements (17, 18) being connected via linkages (22, 23, 24) to output shafts (20, 21) of an adjustment unit (19). The steering and gear-changing movements of the driver are transmitted via input shafts (25, 26) into the adjustment element (19) where they are converted at the output shafts (20, 21) into movements of the actuation elements (17, 18). The connection of the gear-changing and steering movement with the actuation element movements of the primary units (17, 18) is effected by means of two planetary gears which are coupled to one another, one central gear (29) of which is connected to the output shafts (20, 21) whilst the webs (30) are connected to the input shaft (26) for inducing the gear-changing movement and the other central gears are connected to the input shafts (25) for inducing the steering movement. <IMAGE>

Title: Set of structural elements for forming a masonry wall, in particular for stabilising an embankment, and use of the set of structural elements
Inventor: ZINDEL BERNHARD
IPC: E04B2/02
Filed: 1980-05-13
Abstract: A masonry wall is constructed essentially from two types of prefabricated structural elements, that is to say cross-sectionally square, straight or curved profile elements (1) and connecting elements (2). The latter are provided at the top and bottom with cutouts (2a, 2b, 2c, 2d, 2e, 2f). In each case at least two connecting elements (2) are arranged between two pairs of profile elements (1) arranged one above the other. In this arrangement, the profile elements (1) and connecting elements (2) rest, where cutouts (2a, 2c, 2d, 2f) of the latter are located, one upon the other. The cutouts are such that a horizontal force F, directed transversely to the profile elements, can be transferred from the respectively upper structural elements to the structural elements located directly beneath. The cutouts (2a, 2b, 2c) located on the upper sides of the connecting elements (2) are offset with respect to the cutouts (2d, 2e, 2f) located on the lower side, with the result that the retaining masonry wall slopes even if the connecting elements (2) are in an essentially horizontal arrangement. <IMAGE>

Title: Method for representing electrical radio-frequency signals and circuit arrangement therefor
Inventor: BENCZE JOZSEF
IPC: G01R13/34
Filed: 1977-04-25
Abstract: From a radio-frequency signal at the input (1), a time-expanded, shape-conformal image at a lower frequency is generated in that a synchronisation between the signal to be measured and the signal of a sampling oscillator (12) is effected in a first operating mode of the arrangement with the aid of a feedback. With the synchronisation signal obtained in this manner at the output of a comparator (7), the signal to be measured is then sampled at the input (1) in a second operating mode. As a result, a much higher sensitivity can be achieved even at higher frequencies. <IMAGE>

Title: Process and appliance for making a non-conductive porous grinding body electroconductive
Inventor: INOUE KIYOSHI
IPC: C23C18/31
Filed: 1975-10-07
Abstract: The appliance for making electroconductive a grinding disc (3) made of porous, electrically non-conductive material consists of a plating chamber (10) with mounts (3a) for the grinding disc. From storage vessels (11, 12), plating solution is pumped into the plating chamber by means of a cylinder (4) and an associated piston (7). The solution remains in the plating chamber for a time which is sufficient to deposit the major part of the metal from the solution into the pores of the grinding disc. The spent solution is then drained and replaced by fresh solution. This ensures that the solution after the residence time is largely depleted of metal and the metal is forced to be deposited mainly in the plating chamber and thus in the grinding disc. <IMAGE>

Title: Clarification of effluents - from paper mills
IPC: C02F1/52
Filed: 1971-03-11
Granted: 1972-10-27
Abstract: Such effluents carry large quantities of suspended matter in the form of natural and synthetic fibres and fillers, such as kaolin and talc. The plant consists of a cylindrical settlement tank, an aerator and a reoxygenating tank. The settling tank has a conical base so that the extracted matter can slide into the chute to the lowest point and be recycled to the paper-making plant. The waste effluent is introduced through a pipe in the axis of the tank and coaxial with a deflector cone. The suspended matter is removed from the water by gravity; the latter rises progressively to the upper part of the tank and overflows freely from a weir fixed around the external wall. It then flows into an aerating column over a series of zigzag baffles until it reaches an aerating tank where air is injected into the water through a series of nozzles in order to accelerate the reoxygenation of the clarified water before its discharge into the river. Thus the extracted fibre can be recycled and the water clarified simultaneously before its evacuation.

Title: Fixing of labels between two opposite surfaces - two articulated arms hold label in between surfaces
IPC: G09F3/18
Filed: 1973-04-19
Granted: 1974-11-15
Abstract: A means of fixing between opposite surfaces, lightweight objects, in particular labels, has two arms of appropriate length which can move around a common pivot axis. The pivoting of the arms in at least one direction is restricted by a stop. The free extremity of each arm has means of fixing when they come into contact with the surfaces between which the label is to be fixed, the label being fixed to the pivoting axis of the arms. The displacement of the two arms is limited due to the fact that near the joint in one of thearms is a shoulder which corresponds with a part of the other arm to form a stop. The shoulder follows a direction oblique to its longitudinal axis. In the fixed position the jointed arms make an angle of 185 deg. between each other.

Title: Synchroniser for a gearbox - tension springs normally prevent contact between pinion and synchronising ring
IPC: F16D23/06
Filed: 1973-10-31
Granted: 1975-05-30
Abstract: A hub (1) keyed to shaft (2) is splined to sleeve (5) movable by a gear lever fork. Within the hub is a synchronising ring (8) with three tapering axial projections (12) engaging in hub recesses so the hub rotates the ring. Tension springs (19) correct the hub and ring so the ring does not engage a pinion (11) rotatable on the shaft. Movement of the hub towards the pinion causes the end faces (12a) of the projections to engage rings (13), containing spring loaded balls (15) locking the hub and sleeve, and push the ring (8) onto the pinion to brake or speed up the latter. Rotation of the ring w.r.t. the hub locks the ring onto the pinion and further sleeve movement causes the sleeve to engage teeth (22) on the pinion.
