Title: Method for the partial metal coating of plug connector contact pins, and a screen for carrying out the method
Inventor: KRAUTER ALFONS DIPL-ING
IPC: C25D5/02
Filed: 1983-01-26
Granted: 1984-03-29
Abstract: The invention relates to a method for the partial metal coating of plug connector contact pins, in which the plug connector contact pins are held in a pin strip at their upper end and are guided with their lower ends which are to be coated flowing through a spray bath or wave bath, and also relates to the associated screen, which is to be pushed onto the pins. The pin contacts of the plug connectors are provided with a galvanically deposited noble-metal layer, because of the required reliability, in order that the specified electrical contact resistance does not exceed a maximum value. However, this design requirement does not need to be met to the same extent for all surfaces of the pin. In conventional methods, more noble metal is therefore consumed than is absolutely necessary for the technical application. In order to save noble metal, the invention thus provides a method in which screens (20) which are conveyed from the channel end to its start are pushed onto the pin contacts (16) by means of a plugging-on device (17) in a firmly mounted guide channel (12) above transportation wheels (14, 15) which project into the guide channel (12), run in synchronism with the contact pin strip (13) and are like gear wheels, and, after passing through a spray bath or wave bath, are stripped off again by means of a stripping device (19) and are inserted into the guide channel again in order to circulate again. <IMAGE>

Title: Piston ring
Inventor: BRAUERS BERT DR
IPC: F16J9/20
Filed: 1983-02-24
Granted: 1984-09-20
Abstract: In a multi-part piston-ring system which comprises essentially a spreader spring and at least one multi-piece oil ring, it is proposed to profile the multi-piece oil ring in such a way in the region of its inner circumferential surface that, if the said ring is twisted in the installed condition, the inner contact zone formed with the corresponding groove wall is displaced radially towards the outer contact zone of the spring with the multi-piece oil ring. This measure ensures that, when there is a considerable reduction in the tangential force of the spreader spring, the multi-piece oil ring nevertheless maintains a stable position in the groove in the operating condition. <IMAGE>

Title: Circuit arrangement for the functional testing of a sensor for the torsional loading of the shaft of a motor-driven tool
Inventor: MAJIC MILIVOJ DIPL-ING
IPC: G01L25/00
Filed: 1985-03-07
Granted: 1986-07-24
Abstract: The invention relates to a circuit arrangement for the functional testing for the torsional loading of the shaft of a motor-driven tool having two comparators to each of which the output signal of the sensor is fed and which are designed in each case for outputting a characteristic signal when the output signal of the sensor overshoots or undershoots an upper limiting torque value or a lower limiting torque value. It is the object of the invention to increase the reliability of screw connections and the like, in which use is made of sensors having strain gauges, by the early detection of a system error in the sensor circuit. This is achieved according to the invention when the upper limiting torque value and the lower limiting torque value are dimensioned, when the shaft of the tool is still unloaded, in accordance with the torque which counteracts the starting torque of the drive motor and is determined by friction and mass (Fig. 3). <IMAGE>

Title: Device for preventing the dripping water caused by thermal expansion in open hot-water storage tanks
Inventor: KEMPER HEINER
IPC: F24H9/12
Filed: 1986-09-12
Granted: 1987-10-22
Abstract: A device for preventing the dripping water caused by thermal expansion for open hot-water storage tanks is specified. Provision is made for an inlet and an outlet, a variable-volume first chamber communicating with the outlet and having a movable enveloping wall, and a variable-volume second chamber communicating with the inlet and adjoining the enveloping wall. A valve and a small compensating opening are provided in a common enveloping-wall section between the first and second chamber. In the case of pressurisation of the second chamber, the enveloping wall moves from its normal position, against a restoring force, into a working position, opening the valve, with reduced volume of the first chamber, and in the case of pressure relief of the second chamber, the enveloping wall moves back, under the restoring force, into the normal position, in which the valve is closed, and in doing so sucks water out of the storage tank into the first chamber. <IMAGE>

Title: Multiple drill pipe - allows limited inner pipe projection to facilitate coupling to other drill pipes
IPC: E21B17/18
Filed: 1992-04-03
Granted: 1993-09-16
Abstract: A multiple drill pipe has an outer pipe (10) coupled to one or more inner pipes (11), the outer and inner pipes being relatively rotatable and having axially cooperating interlocking parts. The novelty is that the interlocking parts are designed to allow limited displacement of the inner pipe (11) so that it can project alternately from each of the two ends of the outer pipe (10). ADVANTAGE - The inner pipe can project, while still being interlocked with the outer pipe, to facilitate e.g. screwing to another multiple drill pipe so that one operator can connect the drill pipes.

IPC: C02F9/00
Filed: 1994-07-15
Granted: 1995-10-26
Abstract: A prior art permeable treatment bed for the purification of contaminated ground water streams in situ comprises a trench which runs across the ground water flow (5, 5') in the ground water duct (1, 1') and is filled with a water-purifying material (14); there is no provision for replacing used treatment material (14). According to the invention, a water-permeable (12) double-walled structure (11) is erected in the trench filled with processing material (14), using prefabricated elements each consisting of two plates (8, 8') and a transverse strut (9); these are placed in rows next to and on top of one another on a series of U-shaped bottom stones (15). The double-walled structure (11) allows replacement of the filler material (14) where necessary, without the risk that the natural trench walls (6, 6') or a filter-stable gravel layer (7, 7') adjacent to the wall structure (11) will collapse. The replacement of the filler material (14) is effected preferably using mobile suction/forcing pumps; it is also possible, using suction pipes and water supply ducts introduced into the interior of the double wall (11) (the water supply ducts also allowing filler material which has become choked with mud during the operation of the treatment bed to be flushed away) to flush the filler material (14) out and draw it away by suction.
