Title: Governor for injection pumps
Inventor: HARTMANN ERNST-SIEGFRIED
IPC: F02D1/10
Filed: 1987-10-01
Abstract: Internal combustion engines require a governor-side increase of the injection quantity at low engine speed in order to achieve a desired torque increase. This is generally produced by a torque control cell in the governor, which is acted upon by the centrifugal weights rotating at a speed varying as a function of the engine speed. Since such components are subject to tolerances and thereby have to be adjusted during assembly, it is proposed to find a solution which is of simple design construction and does not require any basic adjustment. To this end, the governor levers, to which the centrifugal weights are fixed, are of flexible design. They are therefore deformed as the speed rises and the centrifugal weight loading increases and therefore represent a control rod travel varying as a function of the engine speed. <IMAGE>
Patent DE-3733474-A1 (DE)
Inventor: RILLY GERARD DR
IPC: H02M3/338
Filed: 1987-09-30
Abstract: The power supply circuit has a bridge rectifier (1) at its input connected to a primary winding (2) of a transformer (Tr). Connected to the other end of this winding is a switching transistor (T1) which is alternately blocked and rendered conductive by an oscillator (o). Voltage pulses from the transformer are passed to a rectifier (12) to obtain a control voltage (Ur) applied to an input connection (f) of the oscillator so that its operating frequency is lowered as the control voltage is reduced. This control voltage also controls the switching on time of the switching transistor, stabilising its operating voltage.

Patent DE-3806229-A1 (DE)
Title: Method and device for testing the permeability of workpieces
Inventor: VEH HERBERT
IPC: G01M3/26
Filed: 1988-02-26
Abstract: For the determination of leaks, the invention proposes a device with which a pressure difference is generated over the test location, in that a high pressure is built up on one side. On the downstream side of the test location is arranged a measuring cell of small volume, which is connected to a pressure sensor. In the presence of a leak, a pressure proportional to the leakage builds up rapidly in the measuring cell. Deaeration of the measuring cell is carried out by means of a magnetic valve. The sealing of the measuring cell against the device is achieved by means of sealing rings which can be pressed together axially.
Patent DE-3827786-A1 (DE)
Title: Sealed push-button switch
IPC: H01H13/06
Filed: 1988-08-16
Abstract: The subject matter of the invention is a sealed push-button switch having a sealing shroud (16) consisting of rubber-like material which is fitted on a push-button part (15) and a housing (1) of the push-button switch such that the boundary surface between the push-button part (15) and the housing (1) is protected against any ingress of foreign bodies into the push-button switch mechanism. An annular bead (16a) which is constructed on the edge of the shroud (16) is inserted into a circumferential groove (17) which is provided all round the push-button part (15) in the housing (1), and is rolled in there thermally. Since the bead (16a) is elastically compressed, the result is thus that not only can a favourable sealing effect be achieved as a result of increased contact pressure, but also improved mechanical fitting as a result of the increased resistance to forces which try to pull the bead (16a) out of the groove (17). <IMAGE>

Title: Control water system with radially external control valve for centrifugal separators
Inventor: PARDESS KLAUS
IPC: B04B1/16
Filed: 1988-11-07
Abstract: The invention relates to a control water system with radially external control valve for centrifugal separators with an axially movable piston slide which, during operation, opens and closes mud discharge slots located radially on the outer edge of the drum, and in which control water system the control valve is connected to the control water feed system via control water channels and a control water collection chamber. The control water channel is constructed according to the invention with a nozzle-shaped opening in the direction of the control water collection chamber, which opening is dimensioned in such a way that a constant liquid level is maintained in front of this opening and the amount of control water which enters the control water channel through this nozzle is 1.2 times the amount of control water which leaves through the valve nozzle of the control valve. This design ensures that a control water system is produced which operates independently of the supplied control water pressure and has a continuously constant opening time of the mud discharge slots for the respective partial mud clearance.

Title: Splicing device for optical fibres
Inventor: VEITH GUSTAV DR PHIL
IPC: G02B6/255
Filed: 1988-11-09
Abstract: The splicing device is equipped with two fibre-holding plates (1, 2), in the case of which a light source (10) is arranged at the end of a first optical fibre guide (7') and a light detector (11) at the end of a second optical fibre guide (8'). After notching and separating the fibre projections from optical fibres (3, 4) which are fixed and mutually overlap, a fibre holding plate is rotated through 180@ about a longitudinal axis (9) arranged between the guides (7, 7', 8, 8'), the fibre projections being aligned with respect to each other. They now form an optical control channel, by means of which the actuating drives are controlled until an optimum light transmission is obtained. At the same time, the fibre ends of the optical fibres (3, 4) are in this case accurately adjusted as well in the permanently correlated guides (7, 8) and can subsequently be spliced. In an alternative solution a fibre holding plate is laterally displaced by a guide distance and the optical fibres to be spliced are aligned by means of two optical control channels so as to be exactly flush. <IMAGE>

Title: Filter device
Inventor: ZOLLER ERNST
IPC: B01D46/00
Filed: 1989-01-10
Abstract: The invention relates to a self-cleaning filter device for keeping dust particles out of the combustion air of internal combustion engines. In order to keep the thermal stress small and in order to make the filter small in size, the filter device is arranged in the cooled combustion air stream downstream of the charging air cooler. Since self cleaning by means of an automatic cleaning device which operates using the pressure difference between charged air and atmosphere enables the need to change filter elements at regular intervals to be eliminated, the arrangement of the filter device is not restricted to accessible points. In particular, this permits a flow-optimised arrangement of the filter device. <IMAGE>

Title: Method for connecting terminals to varnish-insulated wires
Inventor: ROY AROON COOMAR SINHAR ING GR
IPC: H01R43/02
Filed: 1989-04-05
Abstract: Connections between varnished copper wires (4) and terminals (2) have previously been produced by soft soldering, it being necessary to remove the varnish insulation of the varnished copper wire (4) in advance. The welding of a varnished copper wire (4) to a terminal (2) by means of a barrier-gas welding method in the past led to a joint which was not permanently stable, particularly in the event of a vibrating load. As a result of the use of a sleeve which is fitted over the terminal (2) and the varnished copper wire (4), a weld is produced between the three parts. Contact can be made with the metal sleeve (3), without any problems, by means of a contact rail (1). The varnished copper wire (4) is partially embedded and partially fused within the resulting welded bead (6). Such a connection is electrically conductive and mechanically robust. <IMAGE>
