Patent DE-3636139-A1 (DE)
Title: Brake cylinder pressure regulator for air brakes of vehicles
Inventor: HOMMEN WINFRIED DIPL ING
IPC: B60T8/64
Filed: 1986-10-24
Abstract: The brake cylinder pressure regulator converts an electrical brake request signal Usoll into an actuating signal B for a braking force regulator, the actuating signal B being switched immediately after the start of braking to a maximum pressure medium passage through the brake valve. After a period of time T approximately corresponding to the attainment of the applied condition, the actuating signal B is adjusted in such a way that the brake valve is set approximately to the brake application pressure and is correspondingly reduced in its throughflow cross-section. As braking progresses, the actuating signal B is varied according to the brake request signal Usoll. Due to the maximum actuation of the brake valve at the start of braking during the period T, the applied state of the braking force is attained very rapidly and sensitive control of the braking force is then possible. <IMAGE>

Title: Power-assisted steering system for motor vehicles
Inventor: KREHAN PETER DIPL ING
IPC: B62D6/02
Filed: 1987-02-20
Abstract: A power-assisted steering system for motor vehicles has a drive assembly which supports manual steering is operated by an electric motor and acts, in the direction corresponding to that of manual steering, on a linkage component which influences the degree of steering lock. The drive assembly can be switched on by a speed-dependent switching device only at low travel speeds, and when a specific travel speed is exceeded it can be switched off. The connection and disconnection of the drive assembly can be controlled as a function of the torque applied manually to the steering wheel. The drive assembly is, in a manner known per se, a pressure-fluid-actuated adjustment cylinder, and a pump which is operated by an electric motor serves to supply the pressure fluid to the adjustment cylinder. In this way, further improvement in the power-assisted steering system characterised in the main patent is achieved in the sense of an uncomplicated design and a low requirement for space.

Title: Inking-unit drive of a printing machine
Inventor: REICHEL KLAUS T DIPL ING
IPC: F16H35/02
Filed: 1987-04-01
Abstract: Known inking-unit drives, which produce an uneven movement of the ductor roller as well as a rotary step-back from time to time, have an increased running unbalance and increased wear due to the flank change of moving parts. The magnitude of the rotary step-back which can be brought about is also limited to a minimum amount in these cases. The new drive is intended to eliminate these disadvantages. A wheel crank mechanism having at least four links and operating as a pilgrim-step mechanism is arranged between a gear which drives the ductor roller and a gear which introduces the drive energy from the main drive of the printing machine or a separate motor. In the design of the drive, the invention permits a wide variation range for the degree of non-uniformity of the transmission and the magnitude of the rotary step-back in all known types of inking units. In a further development of the drive to form a five-link wheel crank mechanism, it can also be adjusted during operation. In conjunction with a differential planetary gear mechanism connected ahead of the wheel crank mechanism, in a vibrator-type inking unit the inking is also variable within a wide range.

Patent DE-3717399-A1 (DE)
Title: Method for bit rate reduction
Inventor: VOGEL PETER DIPL ING
IPC: H04N19/60
Filed: 1987-05-23
Abstract: The method described is used in the coding of a signal which consists of a sequence of digitally represented signal values and contains a signal value A which occurs most frequently in uninterrupted sub-sequences. A first step of the coding consists in that a Huffman codeword is allocated to each uninterrupted subsequence of signal values A having the length 0, 1, 2 and so forth together with the signal value following the sub-sequence. If the signal is structured in equally long blocks, a check is made as to what advantages or disadvantages follow the non-transmission of the last Huffman codeword of a block. If the advantages predominate, the last Huffman codeword is not transmitted and the check is repeated with the preceding Huffman codeword as the last codeword. A special application for the method described occurs in the coding of video signals, particularly in the coding of the serial elements of so-called coefficient blocks. A coefficient block consists of 64 elements. The signal value 0 occurs here most frequently in uninterrupted sub-sequences. If Huffman codewords are not transmitted when the method described is used, so many elements with the value 0 are specified in the decoding of the received Huffman codeword into elements of the coefficient block until a total of 64 is obtained.

Title: Load-dependent reactive-current compensation
Inventor: MECKE HUBERT PROF DR
IPC: H01F27/42
Filed: 1987-07-07
Abstract: The invention relates to a load-dependent reactive-current compensation with compensation capacitance for transformers whose secondary operating voltage is considerably smaller than the no-load voltage, as they are for example applied in arc welding with so-called small transformer welders. It is the object to reduce the outlay in terms of material and to enlarge the application range of the transformers with predetermined primary connection parameters. In addition, there is the object of developing a reactive-current compensation which acts load-proportionally across a wide range without switching devices and additional windings, which does not over-compensate in no-load and in which the primary short-circuit currents are not larger than the primary nominal currents. According to the invention, the object is achieved by arranging a compensation capacitance in series with the secondary winding of the transformer and of the load. The capacitive reactance of the compensation capacitance is approximately the same in terms of magnitude as the inductive equivalent reactance acting on the connecting points of the compensation capacitance, or is between this inductive equivalent reactance and twice the inductive reactance of the leakage inductance for larger output currents.

Title: Solar-powered railway
Inventor: RIENKS GERD
IPC: B60L13/00
Filed: 1987-09-18
Abstract: There are projects which are not undertaken by individual entrepreneurs although it would be beneficial for the wellbeing of the state. The prevailing tax systems prevent such efforts since the state demands taxes even if entrepreneurs themselves do not earn anything. The planned solar-powered railway provides millions of elderly citizens with a cost-free transport means which always functions when the sun is shining and large numbers of people wish to travel to the countryside. The solar-powered railway operates with solar energy and is therefore good for the environment and fulfils the needs of old-age pensioners. At the same time, the overloaded motorways are kept free for long-distance traffic. The cleaning of the solar panels could be performed by local agriculture workers who are now looking for new work because their traditional sources of income have been incorrectly planned and there has been no provision of new infrastructures. The ailing steel industry and innovative solar technology would also be given new impetus. Additional infrastructure (country guest houses) could be given a new chance, biotopes could be established and protection of the countryside could be made more attractive for agriculture workers (old-age pensioners with grandchildren are more interested than travellers hurrying south to sunny holiday destinations).

Title: Feed wheeled vehicle for transport and expansion of bridge parts for the purpose of laying by means of an armoured laying vehicle, and expandable bridge part
Inventor: WAGNER GERHARD DIPL ING
IPC: E01D15/127
Filed: 1987-11-06
Abstract: In a known feed wheeled vehicle, individual track girders of a bridge half are transported on the vehicle in a vertical compact upright position and, prior to transfer onto an armoured laying vehicle, moved apart by means of a vehicle hydraulic system, swivelled through approximately 90@ towards each other, and subsequently the transverse girders of the track girder are connected to each other. Such an operation is time-consuming and difficult for operators to carry out in unprotected open terrain. A feed wheeled vehicle (1) for transport and expansion of bridge parts (2, 3) for the purpose of laying the bridge parts by means of an armoured laying vehicle at a bridging point is proposed, which feed wheeled vehicle (1) has an auxiliary frame (4) behind the driver's cab, the auxiliary frame having, in particular, a front supporting beam (5) having a hydraulically actuable bridge part expanding device (6), a rear extension arm (7) having a bridge part expanding device (8) and two bearing rails (9) having an expanding device (10) and chain drive (11). An expandable bridge part (2, 3) comprises an expandable or foldable transverse girder (16) comprising two girder halves (19) which are coupled to each other. By means of the vehicle hydraulic system, an expandable bridge part can be virtually fully automatically expanded and contracted again into a compact transport position. <IMAGE>

Title: Control system for a motor vehicle
Inventor: JOOS HEINZ-GUENTER
IPC: G01D5/58
Filed: 1987-11-12
Abstract: In order to supply power to an electronic control device (1) in a control system for a motor vehicle, it is proposed to use a light sensor (10) as energy source, an optical waveguide (11) and a photoelectric element (2) which is connected thereto and is connected by electrical outputs (4, 5) to electrical supply inputs (8, 9) of the electronic control device (1). By using the light sensor (10) in conjunction with the waveguide (11) and the photoelectric element (2) for supplying power to the electronic control device, a potential isolation of the electronic control device from the rest of the electrical system of the motor vehicle is achieved. As a result, in particular RF interference on the electrical system of the motor vehicle cannot pass through into the electronic control device (1) and the electronic control device (1) cannot output radiation via the electrical system of the motor vehicle for example by means of a quartz of a microcomputer. <IMAGE>
