Title: Channel regulation for telegraph system - using signal current measuring and regulation circuit on local side of exchange or multiplexer
Inventor: NIETHAMMER DIETER
IPC: H04L25/06
Filed: 1980-07-08
Abstract: Channel switching and regulating equipment connects telegraph terminals to an exchange or multiplexer. A two wire line (LG) connects the teleprinter terminal to the regulator switch (KA) and a three wire line (UMP,ED,SD) connects the switch unit (KA) into the multiplexer or exchange. The switch unit (KA) contains a regulator circuit (RG) which responds to the actual value of telegraph signal (IT) and outputs a signal (e1,e2,e3,e4) according to the deviation from a reference value, to the scanning generator (TSG) so that an output binary signal into the switch output regulator (SCHR) outputs constant level positive and negative signals to line (LG). These values are in accord with the received signals (ED) and polarity change signals (UMP) from the multiplexer/exchange (UE fig 1). The third wire connection to the exchange is the send wire (SD).

Title: Sealing ring for hydraulic piston - has inner sloping surface forced inwards by tensioning ring in contact with outer sloping surface
Inventor: EDLUND ROY DIPL ING
IPC: F16J15/3208
Filed: 1980-07-10
Abstract: The seal for a hydraulic piston or piston rod consists of a sealing ring (1) enclosed by a tensioning rinq (2), both of plastics material, housed inside a groove (32) inside one member (4) with the sealing ring held against the other member (5). The tensioning ring is approximately square in cross section, with rounded corners, and rests against a sloping surface (8) of the sealing ring. This tends to force the other face (9) of the sealing ring, which also slopes, against the second member, assisted by the force applied from the high pressure side. The outer sloping surface (8) is at an angle of between 10 and 15 deg. to the longitudinal axis (I or II) of the piston.

Title: Electric clock drive for stepping motor - has meshing gears with damping liq. in gap between two adjacent teeth
Inventor: RUEB WALTER
IPC: F16H49/00
Filed: 1980-07-24
Abstract: The drive intends to reduce the noise on backlash of gears after each switching step. On one of the meshing gears (2) is applied a damping liquid in the tooth gap (5) between the tooth flanks of two adjacent gear teeth (4). This liquid fills the gap, at least partly, and sticks to the tooth flanks. Pref. viscous lubricant used for this purpose. A magnetic liquid may be used, sticking to the tooth flanks due to magnetic fields effective in the gap sections. The teeth of the gear, carrying the magnetic liquid, are also magnets, the opposite flanks of adjacent teeth forming north and south poles respectively. The other gear (3) is then made of non-magnetic material. The gear teeth may form alternately a north and south pole, but it is also possible to form two flanks of the same tooth as a south and north pole respectively.

Title: Gradual continuous tower crane jib rotation control - using motor shaft brake with coil signal derived from potentiometer
IPC: B66C13/30
Filed: 1980-08-20
Abstract: A device controlling the rotational drive and turning speed of a movable object is esp. suitable for control of the jib of a tower crane which has a large moment of inertia. The controller ensures that the speed is regulated gradually and continuously in starting. Stopping, and operating manoeuvres. This prevents dangerously large torsional forces being applied to the crane tower. A control circuit controls the voltage between connections to the excitation winding of a braking element on the motor shaft. The controller contains a variable control resistor with one end at constant potential and the other connected to an adjustable calibration resistor which feeds an amplifier supplying in turn the brake excitation coil. The controller and brake are connected to the supply voltage by a switch only when the motor is powered.

Title: Grape harvesting machine
Inventor: SCHNEIDER FRITZ
IPC: A01D46/00
Filed: 1981-01-21
Abstract: Harvesting is the most work-intensive part of viticulture and, even today, is still done predominantly by arduous manual work. The object set - that of making the heavy manual and transportation work easier, speeding up the harvesting process and providing the possibility of qualitative selection on a scientific basis - has, according to the invention, been solved by a machine which is towed through the rows by a conventional tractor and is operated hydraulically. By a combination of manual work and work performed by the machine, the harvesting process is performed in a gentle manner. The harvesting personnel sit behind conveyor belts mounted to the right and left of the machine at the level of the grapes and transfer the cut grapes to the conveyor belts, from where they pass via elevators into the hopper. The belts and seats can be moved hydraulically to allow adaptation to different row widths. The hopper can be tipped, likewise hydraulically, onto any of the customary transfer vehicles. The operating width of the machine can be varied for use in almost all wine-growing concerns.

Title: Method for controlling the fuel feed to an engine and device for performing the method
Inventor: SPIELVOGEL ERNST
IPC: F02D33/00
Filed: 1981-09-14
Abstract: A method is described for controlling the fuel feed to an engine, preferably a gas, steam or internal combustion engine, in a vehicle together with a device for performing the method. In order to manage without modifications to the engine construction, it nevertheless being possible, by simple means, to quickly fit fuel saving devices even to vehicles on the market and to at least temporarily reduce the fuel feed, it is proposed according to the invention that the fuel feed be periodically throttled from the rated output and after a certain period increased again back to the rated output, the duration of the throttling and/or the cycle preferably being preset. The throttling device may be controlled electrically, electronically, mechanically, hydraulically and/or pneumatically. <IMAGE>
Patent DE-3137601-A1 (DE)
Title: Steering damper for mounting a steerable front wheel of a motor vehicle
Inventor: RIST ALFRED
IPC: B62D7/22
Filed: 1981-09-22
Abstract: In a steering damper for mounting a steerable front wheel of a motor vehicle, the design is such that it reaches its highest damping value at the dead centres of movement resulting from steering oscillations of a wheel carrier of the mount which bring about wobbling of the wheel. The steering damper is thus already capable of causing effective interference in, or completely suppressing, oscillations of a small amplitude which become effective about the steering axle at the beginning of oscillating movements. In contrast hereto, the hydraulic steering damper which is usually provided in wheel mounts has a damping value of zero at the dead centres of oscillating movements about the steering axle. Therefore, there can be no appreciable build up of hydraulic force in the steering damper which could possibly prevent wobbling of the wheel.

Title: "Projection device in motor vehicles to display map material"
Inventor: KIENLE EWALD
IPC: G09B29/10
Filed: 1981-09-30
Abstract: Projection device to display map material in a motor vehicle, in each instance map extracts being applied to a film as carrier material which is movable with motor drive in the region of an optical system (1). A central control unit (12) accepts a target value from an input keyboard and compares this target value with identification features on the film in the form of codings, which are scanned by a code transmitter. If the desired map extract as target value in the encoded form is in agreement with the map extract which is situated at this moment in the image plane as it passes through under motor drive, then the central control unit stops the motor drive of the film movement. The desired map extract is projected onto a ground glass plate or is reflected into the windscreen, i.e. virtually directly within the field of view of the driver. <IMAGE>

Title: Assembled hinged concrete slabs made up of small elements
Inventor: KREBBER HEINZ
IPC: E01C5/08
Filed: 1982-01-07
Abstract: The construction consists of geometrically shaped concrete blocks which are joined together as a row by means of, for example, plastics reinforcement (rods or cables), said blocks when placed side by side forming vertical openings into which rows of concrete blocks likewise joined together by reinforcement can be introduced, for example transversely, and thus produce a hinged slab effect. See items a), b), c) and e) in the Figure. The plastics reinforcement is intended to prevent corrosion. The construction can be used, for example, in the construction of pavements, roads and squares and in water engineering. It is intended to provide an alternative for     - large-sized concrete panels,   - asphalt or bitumen concrete,   - normal paving,   - individually-laid dyke or embankment protection blocks.   The assembled hinged concrete slab can   - adapt to relatively large or relatively small ground movements according to the hinged joint strength and the block size, - compensate any compressive and thrust forces occurring depending on the position and tensile strength of the reinforcement, - lead away, and even infiltrate, water more readily through joints and undergo vertical movements when there is frost. Said slab largely combines the advantages of single paving with those of a rigid concrete panel and is insensitive to heat and penetrating damp.

Title: Fluctuation mat made of foamed material
Inventor: REUTER RICHARD
IPC: A47C23/00
Filed: 1982-03-18
Abstract: In a fluctuation mat (1) which is made of foamed material and which is composed of individual square, exchangeable foam parts (12, 12', 12''), these parts are releasably fastened with a burred closure (13, 14) on a base plate (11), the size of which corresponds to that of the fluctuation mat (1). It is possible in this way to detach the foam parts (12, 12', 12'') simply and quickly in a specific region from the base plate (11), for example for providing a free space. Thus, a patient can provide himself with individual relief from pressure points, especially since there are foam parts (12') provided with bevellings (15) and of different hardness, and can adjust the seating position. The outlay on production of the fluctuation mat (1) which can be used as a seating cushion or even as a mattress is low because it is only necessary to provide one base plate (11) with a burred tape (13) and the individual foam parts (12, 12', 12'') with a cover (14) made of fleece or felt. <IMAGE>

Title: Automatic adjusting device for a brake actuating device
Inventor: HEIBEL HELMUT ING GRAD
IPC: F16D65/14
Filed: 1982-05-28
Abstract: Arranged between a hydraulically displaceable piston (14) and a mechanically displaceable tappet (24) which are guided in a cylinder housing (10) is a hollow first spindle (42) which is screwed to the piston (14) by means of a right-handed coarse-pitch thread pair (44, 46) free of self-locking. Arranged within the first spindle (42), coaxially with the latter, is a second spindle (6), which is screwed to the piston (14) by means of a left-handed thread pair (68, 70) likewise free of self-locking. The two spindles (42, 66) have mutually complementary coupling surfaces (62, 64), between which a spring (78) maintains a small coupling clearance in the rest condition. In the case of hydraulic brake actuation, the two spindles (42, 66) rotate in opposite directions relative to the piston (14) without being displaced axially. In the case of mechanical brake actuation, both spindles (42, 66) are displaced jointly by the tappet (24) after the coupling clearance has been overcome and the piston (14) is displaced with them; because of the different directions of the two thread pairs (44, 46 and 68, 70) and because of the frictional engagement between the coupling surfaces (62, 64) brought about by the tappet (24), the two spindles (42, 66) can not rotate either relative to one another or relative to the piston (14). <IMAGE>
