Title: Torsional vibration damper, in particular for the clutch disc of a motor vehicle friction clutch
Inventor: LUTZ DIETER DR ING
IPC: F16D13/68
Filed: 1982-07-31
Abstract: The torsional vibration damper, which is suitable, in particular, for the clutch disc of a motor vehicle friction clutch, has two damper parts (13, 17), which can be twisted relative to one another over a limited angle of rotation about a common axis (7) of rotation and together surround at least one, preferably at least three damper chambers (33, 35) sealed off from the outside and at least partially filled with a hydraulic fluid. Arranged in each damper chamber (33, 35) is a rolling element (37) which divides the damper chamber (33, 35) in the circumferential direction into two spaces (39, 41), the volume ratio of which changes during the relative rotation of the damper parts (13, 17). A restricted connection (47) between the two spaces (39, 41) allows compensation of the hydraulic fluid by passing it around the rolling element (37). The damper chamber is formed by two mutually opposite recesses (33, 35) having different volumes in mutually complementary, adjacently opposite surfaces (29, 31) of the damper parts (13, 17), which surfaces move relative to one another during the relative rotation. The circumference of the rolling element (37) is in frictional or positive rotational driving contact with mutually opposite surfaces (43, 45) of the two recesses (33, 35) and rolls in the recesses without sliding. The rolling element is, in particular, of resilient design and clamped in the recesses (33, 35) under its own spring prestress. The rolling surfaces (43, 45) of the recesses (33, 35) are shaped in such a way that, as the torsion angle increases, an increasing prestressing force and hence a restoring torque counteracting the moment of torsion is obtained. A torsional vibration damper of this kind acts both as a hydraulic and a spring damper and permits relatively large torsion angles. <IMAGE>

Title: Electrohydraulic control arrangement for a cutter shield
Inventor: HEITKAMP HERBERT
IPC: E21D9/06
Filed: 1982-08-25
Abstract: The invention relates to an electrohydraulic control arrangement for a cutter shield, with an electronic central computer, having a program selector switch and display unit, and intelligent valve control units which are allocated to the individual cutter cylinders, are connected to one another and to the central computer via a data bus and have valve devices for admitting pressure to the cylinder spaces of the cutter cylinders. According to the invention, the cutter cylinders, as an integral part of their intelligent valve control units, have sensors sensing their piston-rod travel as well as sensors sensing the hydraulic pressure in their cylinder spaces. Here, the microcomputers of the valve control units, which control the stroke of the cutter cylinders, are in each case provided with a memory (RAM) storing the actual-value signals from the sensors and with a program data memory (ROM) storing the desired-value data supplied by the central computer. Absolute synchronism when re-tightening the cutter-shield supporting frame can be obtained by means of the control arrangement.

Title: Speed control system for an internal combustion engine
Inventor: KUETTNER THOMAS DIPL ING
IPC: F02D41/16
Filed: 1982-12-16
Abstract: A speed control system for an internal combustion engine is proposed with a reference value increase from a specific actual speed value at which the difference between reference and actual value varies as a function of operating variables, preferably as a function of the speed of rotation. The aim of this is to make the start of the control process less sensitive to bucking vibrations at relatively higher speeds. A flow diagram illustrates the calculation sequence and the method of reference value tracking.

Title: Process of reducing the consumption of protective gas and the edge oxidation of structural members to be treated in sluice pusher plants with combustible protective gas
Inventor: FRITZSCHE PETER DIPL ING
IPC: C21D1/74
Filed: 1983-03-24
Abstract: A process is described for reducing the consumption of protective gas and the edge oxidation of structural members to be treated in sluice pusher plants with combustible protective gas. The sluices are now no longer constantly flushed by an excess of protective gas fed into the furnace but the amount of protective gas fed into the furnace is reduced to the amount necessary in order to cover the leakage losses and obtain a minimum pressure of 0.5 mbar gauge, and the sluices are flushed merely during the opening cycle up to 5 to 10 seconds after the closing of the outer sluice doors by a stream of nitrogen which corresponds to 1 to 2.5 times the stream of protective gas. By the flushing with nitrogen, smaller variations of the carbon potential established in the furnace are obtained as well as a reduction in the edge oxidation or edge decarburisation as a result of the avoidance of stronger vacuum phases in the furnace. The total gas consumption of the plant decreases.

Title: Integrated circuit strips having connecting leads
Inventor: HERRMANN KLAUS-JUERGEN
IPC: H01L23/31
Filed: 1983-06-24
Abstract: In integrated circuit strips (punched strips, having connecting leads, the problem arises that, because of the escape of encapsulation compound from the housing during the injection process, cutting the connecting leads free presents difficulties and results in premature wear of the punching tool. In order to eliminate this drawback, it is proposed to provide the circuit strip with at least one barrier in each case for inhibiting the outward flow of encapsulation compound at the points where the encapsulating compound which insulates the individual conductor tracks from one another emerges from the housing so that a punching and bending region which is free of encapsulation compound is obtained at the sealing ridge (Fig. 4). <IMAGE>

Patent DE-3332814-A1 (DE)
Title: Sealing test device for the localisation of leaks on hollow bodies
Inventor: PICKEL VOLKER
IPC: G01M3/22
Filed: 1983-09-12
Abstract: Many hollow bodies such as cast parts, etc., have to be tested for impermeability in industry. The differential pressure method with compressed air is mainly used for this. Parts which are not sealed are assorted, again placed under pressure and are dipped into a bath in order to localise the leaks. If a fluorinated hydrocarbon gas, as used in refrigeration technology, is used instead of compressed air, leaks can be detected both by pressure drop and also externally by means of an electrical sensor. This sensor acts in connection with a microprocessor, on which the leakage rate can be preset. In this manner the leaks can be detected in mass production without interruption of the testing process. The special feature of the impermeability test device is that the fluorinated hydrocarbon gas is sucked out of the hollow body after the test process, compressed in a compressor and then liquefied in a condenser. The liquid refrigerant can then be again supplied in gas form via an evaporator to the new hollow body to be tested. Various possibilities exist for the embodiment of the evaporator and compressor, and are described in more detail in the patent application. In this manner, no fluorinated hydrocarbon gas reaches the atmosphere, with the exception of traces which emerge from the leaking point on the parts. These small quantities are out of the testing region ... Original abstract incomplete.
Patent DE-3333486-A1 (DE)
Title: Process for compacting and cleaning sheet metal scrap from household refuse
Inventor: VOELSKOW PETER
IPC: B03B1/00
Filed: 1983-09-16
Abstract: The process uses the positive experience of total refuse comminution in a ball mill, after which the (iron) sheet metal scrap appears squeezed (compacted) as small, very clean clumps. The iron fraction, mainly sheet metal scrap, is separated by means of a magnetic separator before or after a thermal treatment from the household refuse or the combustion or pyrolysis residues, and is after-treated in a rotary drum partially filled with steel balls. The iron scrap portions compacted into small clumps are separated off after the rotary drum, e.g. by a magnetic separator. Without the milling energy to be used in total refuse comminution, and with relatively small capital costs for a very simple rotary drum, an iron scrap having a very small bulk volume is recovered which is as clean and compact as after the comminution of the refuse in a ball mill. In comparison with an after-treatment with a shredder plant, the wear costs are minimal, the bulk volume of the scrap and its degree of purity are still better than those after a shredder plant with subsequent separation of the residual dirt. The process is suitable for all refuse processing plants, such as composting plants, sorting plants, combustion plants or pyrolysis plants.
