Title: Stabiliser for lorry with pneumatic suspension - has rod resiliently supported on chassis via two double-acting hydraulic vibration dampers
Inventor: SCHWERIN WOLFGANG VON
IPC: B60G15/00
Filed: 1978-11-11
Abstract: The stabiliser (6) has a rod (7) rotatably and resiliently connected (8) to the vehicle chassis (4) via two supports, each containing a double-acting hydraulic vibration damper (8). Preferably the latter is a hydraulic damping cylinder connecting the stabiliser to the vehicle body. The ends of the damper above and below the neutral position may be connected via a by-pass. The damper characteristic may vary so as to give stiffer action with increasing load. This system provides greater vibration damping without causing any discomfort to the driver.

Title: Cartridge feed system for revolver - uses sliding gate to operate pins controlling upwards travel towards spring loaded gripping jaws
Inventor: MILLER HANS-PETER
IPC: F41A9/46
Filed: 1978-11-25
Abstract: The cartridge feed system for additional cartridges for a revolver uses two half blocks each with a semicircular recess inside to fit around each cartridge as it is advanced. Each block has a lug projecting from the bottom with a hole through it for a pin acting as a hinge about it. This enables the blocks to act as jaws which swing open and closed to grip and release the cartridge. At one end, is an arched plate which is raised and lowered in the manner of a guillotine, controlled by springs. This in turn controls the action of three spring loaded pins, one central pin controlling the jaws and a pin each side controlling the advance of the next cartridge from below.

Title: Machine tool tool holder - has eccentric transverse bolt to clamp two parts with matching conical surfaces
Inventor: ZUERN WOLFGANG
IPC: B23B31/103
Filed: 1978-12-05
Abstract: The tool holder for a machine tool is made in two parts (1) (11) which are clamped together. One part (1) has a shank (2), which fits into the spindle of the machine tool, and a flange (3) with a conical recess to receive the second part (11). The second part (11) has a transverse hole (15) which is connected to the end face by a slot which is narrower than the diameter of the hole. A bolt (7) with an eccentric middle portion (5) of smaller diameter passes through close fitting holes in the first part (1). When the bolt (7) is rotated its eccentric middle portion (5) grips the surface of the hole (15) to clamp the two parts together.
Patent DE-2853408-A1 (DE)
Title: Powered fret saw blade clamping - involves second clamp under spring force arranged in blade line and thrust direction
Inventor: KOLLER ABRAHAM
IPC: B27B19/10
Filed: 1978-12-11
Abstract: There is a clamping position on the drive side. There is another on the far side of a workpiece or bench, in the system for clamping the saw blade of a fretsaw, with drive activation. The second clamping position (15) is loaded by a force acting in the saw blade direction, or parallel to it, and in the thrust direction of the drive. This also stresses the saw blade for tension with thrusting drive. The force may be exerted by a compression spring (32). The second clamp can be provided by a cone (36), and a socket (23) clamping this against the saw blade (3). This permits more powerful thrust and at the same time use of finer sawblades.

Title: Impact jet mixing system - has two opposed propellers mounted in vessel each recirculating liquid with intense mixing where jets impact with each other
Inventor: BRAUER HEINZ PROF DR ING
IPC: B01F27/71
Filed: 1979-01-03
Abstract: Impact jet mixer is used to mix two fluid phases which have fine solids in them. Two jets are formed by propeller elements which direct the two liq. jets at each other inside a cylindrical vessel. The two jets form an impact face in the centre of the vessel. The vessel can be horizontal or vertical, but the two halves must be mirror images. The jet formation is enhanced by enclosing the propellers inside cylindrical flow baffles. For use with fluid phases esp. where some finely divided solids are present. A required degree of mixing is achieved in an impact jet mixer more rapidly than in conventional mixing systems because it enhances secondary flows and gives adequate fluid in the vicinity of the mixer blades.

The symbols are now printed image-wise on the carrier, can be 'rubbed down' on to a new carrier and removed from this carrier when necessary, using an adhesive film. No residue is left and the carriers are not damaged.
Patent DE-2905195-A1 (DE)
Inventor: RIJANTO HENDRO DR ING
IPC: H02H7/045
Filed: 1979-02-12
Abstract: In each case one power circuit breaker and one current transformer is allocated to the connections of the differential protection device. The secondary windings of the current transformers are connected to a differential relay. This differential relay triggers the associated power circuit breaker when the sum of the currents in the protection object is not equal to zero. An additional circuit is supplied with signals which are derived from at least one transformer secondary current (i1, i2) and the current sum (iDIFF) for both half-cycles. These signals are logically combined. A signal which inhibits the tripping of the associated power circuit breaker is present at the output (A) of the additional circuit when the signal which is derived from the sum current (iDIFF) exceeds an associated response threshold later in time than the signal which is derived from the transformer secondary current (i1, i2). The additional circuit stabilises the differential protection device such that incorrect tripping resulting from a greatly different transfer function of the current transformers is prevented. <IMAGE>

Patent DE-2925379-A1 (DE)
Title: High quality image transfer unit for photocopier - has coupling providing increased play in copy drive so that torque is taken up over one pair of teeth at a time
Inventor: FINKENZELLER JOHANN ING GRAD
IPC: G03G15/16
Filed: 1979-06-22
Abstract: A quality image transfer unit for a photocopier has a toner image receiving curved copy support which rolls over the developed image, the drive for the curved support having meshing gears. The play in the gears is increased to a loose fit by moving the wheels apart or by wide cutting so that the support is dragged by the leading edges of the teeth. The coupling allows accurate synchronisation between the flat image plate and the curved copy support, with a min. of smearing drag. The coupling ensures that the drive is taken over one pair of teeth at a time.

Abstract: The drive pinion for a reduction gear is borne by a key-operated profile cylinder insertable in the lock case, on an esp. residential building outside door. The cylinder bears a drive ring with radial carrier attachment, on its rotatable core. The pinion is a tooth segment ring complementary to this, splaying against spring prestressing, and fitted for setting on the drive ring across the cylinder housing. Holes through the top and bottom of the lock case have a shape concentric to the core, adapted to the periphery of the pinion. The cylinder, with segment ring held under prestressing on drive ring, is insertable in the case top and/or bottom through the holes. On a plug in lock, the drive pinion can be coupled to the cylinder core outside the lock case, using few tools, before the cylinder is introduced into the case and operatively connected to the reduction gear.

Title: Liquid removal tool with sponge or cloth head - has piston-type compression handle for inserting sponge into overflow areas to absorb fluid
Inventor: STIERLE WERNER
IPC: F24C5/00
Filed: 1979-09-20
Abstract: The fluid, e.g. excess oil in an oil boiler is absorbed by a sponge cloth (31) which is inserted in a housing (11) whose base surface (14) is completely or partially open. A compression member (21) e.g. piston is mounted in the housing (11) on the side opposite the base surface (14) where it can be manually displaced in the direction of the sponge by means of a rod system (22,23). For easy exchange of the sponge the housing (11) can have on the side opposite the base a detachable lid (12) in which it is screwed. By compressing the sponge before it is applied to the area of excess liquid the suction effect is sufficient to draw up the liquid.
