Title: Sludge raking mechanism for settling basins - reciprocated by endless rope in guide rails suitable for complete basin enclosure
Inventor: HAVERKAMP WILHELM
IPC: B01D21/04
Filed: 1978-11-02
Abstract: A sludge raking mechanism for rectangular sewage settling basins has the raking blade suspended by a linkage on a tube with rollers, guided in parallel rails along the basin sides. An endless rope drive reciprocates the linkage and urges the tube rollers against the top rail. Curved guide rails ensure that the blade rollers are raised to the bottom guide rail for the return journey of the blade and that the blade is lowered to the basin bottom for the start of the next working stroke. Such a raking mechanism is suitable even for a completely covered settling basin. It has a simple design and can be made at low cost so that crucial parts can be made of high-grade materials to resist corrosive vapours.

Title: Roll gap adjusting unit for rolling mill - where coarse adjustment of gap is made by one electric motor using worm-wheels and forming single subassembly on mill
Inventor: PLAETRICH HEINZ ING GRAD
IPC: B21B31/20
Filed: 1978-11-23
Abstract: In the windows of the mill stand are two hydraulic cylinders each contg. a piston employed to exert pressure on the roll chocks. The two pistons are hollow and possess an internal thread for a pressure spindle, on which a wormwheel is wedged and employed to adjust the total length of the piston and pressure spindle when there is no load on the rolls. Both wormwheels are rotated via two worm spindles driven by one electric motor and forming a single drive unit in a traverse extending from the driving side of the access side of the mil. The invention maintains the advantages of the adjusting unit described in DT2652325 but simplifies the design of the wormwheel driving mechanism.

Title: Multicylinder reciprocating IC engine - has double acting pistons with transfer valves between compression and expansion sides
Inventor: ALBERSINGER GEORG
IPC: F01B3/00
Filed: 1979-01-19
Abstract: The engine has cylinders parallel to the output shaft, arranged in a ring round the shaft. Each cylinder contains a double-acting piston with a passage through it. One side of the cylinder has a pressure operated inlet valve and the other side has a mechanically operated exhaust valve. Air compressed on the inlet side is transferred through the hollow piston and a second, pressure-operated valve in the piston to the exhaust side. Ignition and expansion take place on the exhaust side. The pistons are connected to the output shaft by a swashplate linkage with a bevel gear.

Title: Gettering device for colour TV CRT - has tray supporting arm with extension bent to form sprung bracket for tray snap connection
Inventor: SCHAAL ARTUR ING GRAD
IPC: H01J29/94
Filed: 1979-02-14
Abstract: The getter material for the colour t.v. c.r.t. prodn. is contained in an annular trough, held at one end of a support arm (2). In actual use the support arm may be repeatedly itilised, with only the annular trough (1) being displaced.

Title: Air curtain maintenance structure - consists of top and sides over underfloor air jets with deflector along top
Inventor: BELIN ANDERS KURT HILMER
IPC: F24F9/00
Filed: 1979-03-14
Abstract: The method of forming a hot air curtain over an entrance (1) which could be a factory entrance through which vehicles such as forklift trucks pass, uses a structure outside the opening to maintain the flow. A similar structure could also be installed inside also. This structure consists of a flat roof (7) supported on two sides (6) which a curved baffle plate (9) mounted across the outer edge of the roof, forming a return guide for the hot air striking the roof. The hot air is blown upwards through a grid under the threshold. Alternative arrangements include repositioning the hot air jets, using straight sided and adjustable baffles, also a special trough at the threshold.

Title: Claw coupling of aluminium pressure diecasting - with polyamide rollers as buffers between claws
Inventor: GROTE HUGO ING GRAD
IPC: F16D11/00
Filed: 1979-04-04
Abstract: A claw coupling consists of two halves, each with aluminium pressure die casting around a steel hub with the keyway for the drive shaft. The claws of the two coupling halves are in contact with each other through cylindrical rollers of an electric material, preferably made of polyamide, and have redii of curvature to suit the radius of these rollers. The rollers are guided between an outer ring and an inner ring and have pivots which enter into slots. This is a low-cost coupling with completely indentical halves which can be displaced axially relative to each other.

Title: Rapidly changing reactive current producing system - uses three-phase transformer and compensation capacitors to perform given correction
Inventor: DEPENBROCK MANFRED PROF DR
IPC: H02J3/18
Filed: 1979-05-07
Abstract: The system controls the three currents in the transformer's primary windings independently of one another. A set of capacitors is used to produce compensation reactive power. A correction is made to all currents whenever the sign of the present derivative differs from the sign of the associated mains voltage. The correction current's time derivative is integrated over a given time. A value is selected that is taken as negative between the derivatives of both original wanted currents, the magnitude of whose derivative is not the greatest, thus the correction currents together form a zero system.

Title: Anamorphic optics for infrared detector - uses crossed cylindrical lenses with different focal lengths for asymmetric field of view
Inventor: BLANKENFELD HEINZ DIPL PHYS
IPC: G02B13/08
Filed: 1979-05-30
Abstract: In an infra-red surveillance system, each detector has anamorphic optics with a field of view of 5 deg. in the horizontal plane and 40 deg. in the vertical. This is achieved by two crossed cylindrical lenses with different focal lengths. A short focus lens, with its cylinder axis horizontal, is placed in front of the detector to determine the vertical field. A long focus lens, with its axis vertical, is placed in front of the first lens to determine the horizontal field. The lenses are positioned so that the detector surface lies in their respective focal planes.

Title: Sound head drive for cine camera - has spring mounting with reaction increase of drive pressure
Inventor: KRUMBEIN FRITZ
IPC: G03B31/02
Filed: 1979-11-24
Abstract: A sound head drive for a cine camera has a pressure roller (4) at the end of a pivoted arm (6) to press against the capstan roller (2) in such a way that the pressure increases with the reaction drive. The free end of the arm is spring loaded (10) to increase the roller pressure. The roller or the capstan has a central padded section to locate the film, with the pressure limited by the hard outside edges. The pressure on the drive is independent of the operation of the shutter release and allows a simple camera action.

Title: Safety system for speed control of track bound vehicles - has double computer system for monitoring speed etc. and comparing it with mathematical models
Inventor: SCHERF HARTMUT DIPL ING
IPC: B61L3/00
Filed: 1979-12-01
Abstract: The safety system consists essentially of two computers (1,2) to which, independently from one another, the measured true speed, the desired speed and the type of braking are advanced. The first computer (1) takes care of the drive vehicle control and the monitoring of the speed of the train with the help of a mathematical model which simulates the expected travel behaviour of the drive vehicle. The second computer (2) merely monitors the speed ot of the train with the help of another mathematical model which is identical to the first. The computer outputs are both fed to switch off units (6,7) which give out disturbance signals in the absence of a test impulse, the type of braking applied depending on whether the train is passenger or goods.

Title: Throttle control for IC engine - has linkage from accelerator adjusted by feedback from engine suction
Inventor: MALLMANN DIETER
IPC: F02D11/08
Filed: 1979-12-27
Abstract: The accelerator pedal (5) is connected by pivoted levers (4.1) to a box (1.2) which contains a spring loaded membrane (1.3). The membrane is connected by further pivoted levers (4.2) to the throttle (7) in the engine air intake (6). The membrane divides the box into two chambers. One of these (1.1) is connected (9) to the air intake downstream of the throttle. The engine suction pressure thus acts on the membrane and varies the distance between the levers joined to the box and those joined to the membrane. This provides an adjustment to the linkage between the accelerator and throttle in accordance with a feedback from the engine operating condition.
