Patent DE-3710521-A1 (DE)
Inventor: KUHN KLAUS ROLAND DIPL ING
IPC: F02P17/04
Filed: 1987-03-30
Abstract: In an arrangement for determining the ignition angle in combustion engines, the cylinder movements are proportional to a rotation of the crankshaft which can be determined by measurement, and a reference angle region (R) is indicated by at least two marks on the circumference of a disc integral with the crankshaft. The upper dead centre of at least one cylinder can be derived from the marks. To ensure accurate measurement of the ignition angle in combustion engines, which is not possible by adapting any conventional upper dead centre sensors, the ignition angle is determined by measuring a time and using a reference angle to derive the ignition angle in real time by simple mathematical operations. The invention is used mainly in vehicle test stands.

Title: Process for producing a holder part with high-precision grooves
Inventor: FINZEL LOTHAR DIPL ING
IPC: B29D99/00
Filed: 1988-03-22
Abstract: When producing a connection between two optical waveguides, the two optical waveguides can be aligned with each other by joining them together at their end faces within a continuous groove. The precision of the groove has to meet high requirements. The object on which the invention is based is to provide a process by which very precise grooves can be produced with as little effort as possible in basic parts of various structures. The object is achieved according to the invention by there initially being produced a rough form of the holder part (1) with a groove (2) and by the rough form of the holder part (1) with the groove being covered over at least part of the length of the groove with a layer of plastic (5) and by the layer of plastic (5) being pressed into the groove of the rough form of the holder part (1) by means of a high-precision tool (3) in the form of a die. At its surface, the layer of plastic (5) takes on the high-precision form of the tool (3) in the form of a die. Thus, the layer of plastic (5) compensates for any unevennesses there may be in the raw form of the groove (2). The tool (3) in the form of a die may be heated in order to improve the mouldability of the layer of plastic (5). The specified process can be used in the production of optical waveguide connectors, on which the optical waveguides to be coupled are centred in a groove. <IMAGE>

Title: Brake spring coupling for adjustment gears, in particular of seat adjustment devices, preferably in motor vehicles
Inventor: KLUETING BERND ING GRAD
IPC: B60N2/225
Filed: 1988-06-07
Abstract: The brake spring coupling for adjustment gears of seat adjustment devices, preferably in motor vehicles, comprises a stationary brake drum, against the inner drum casing of which a helical torsion spring with inwardly bent hook ends bears in a frictionally engaged manner. The hook ends engage with play in the cutout sector of an adjustment bush mounted rotatably on an adjustment shaft. Arranged with play between the hook ends is the sector cam of a transmission member which is connected in a rotationally fixed manner to the adjustment shaft, the sector cam being acted upon by a play-eliminating spring member. In this case, in known arrangements, either the adjustment bush is held with one side bearing on a hook end or the spring member bridges deflectably the play space between one hook end and the sector cam of the transmission member. A new brake spring coupling is now to be produced, which, with simple space-saving means, directly brings about the bearing of one of the two hook ends against the sector cam. To this end, the spring member is supported on the one hand bearing directly against one hook end of the helical torsion spring and on the other hand bearing via the sector cam against the other hook end with the effect of pressing the hook ends apart. As a result, the restoring force of the spring member resulting from the loading of the adjustment gear is supported so that striking noises from the loading of the adjustment gear cannot take effect.

In order to damp resonant oscillations of the centrifugal weights (7) at critical speeds, an oil collecting flange (8) is provided on the injection pump side and extends radially inwards, so that an oil ring (9) forms on the inner circumference of the housing (1b) into which the centrifugal weights (7) enter at critical speeds. <IMAGE>
Patent DE-3837130-A1 (DE)
Inventor: KLANK OTTO
IPC: H04H20/00
Filed: 1988-11-02
Abstract: A satellite radio receiver obtains signals from a satellite receiving installation comprising one or more frequency converters which may, for example, undergo a frequency drift as a result of temperature variations which cannot be compensated by an AFC circuit which is located in the satellite radio receiver and which controls a carrier oscillator for carrier regeneration in a demodulator circuit. According to the invention, a local oscillator for a mixer is designed as a PLL local oscillator (44) which can be tuned in a large or a small increment. The AFC circuit (1) and a synchronizing signal evaluation circuit (40) are corrected to a control circuit (34) by means of which the PLL local oscillator (44) is tuned, outside the control range of the AFC circuit (1), with a large increment in the case of undetected synchronizing signals and with a small increment in the case of detected synchronizing signals until the control range of the AFC circuit (1) is reached. The satellite radio receiver described is suitable for connection to satellite receiving installations which comprise a plurality of frequency converters and therefore deviate the nominal receiving frequency in a summary fashion and for private individual installations which, for economic reasons, possess low frequency stability.

Patent DE-3905825-A1 (DE)
Title: Centrifugal soot separation
Inventor: STARK HELMUT
IPC: F01N3/05
Filed: 1989-02-24
Abstract: According to the invention, an exhaust gas stream is accelerated by a high-speed fan and directed against a stationary wall. The soot particles contained in the exhaust gas impact there and accumulate, while the exhaust gas stream escapes through a continuing branch. The impact wall can be the wall of a cyclone or the closed end of a pipe branch or vessel which can be opened for emptying. In the case of the cyclone, the soot particles accumulate in the lower part and can be removed there, optimally through a lock. By designing the impact surface in the cyclone as an electrostatic plate insulated from the rest of the cyclone, a combination with the electrostatic soot separation method can be achieved, significantly lower electrostatic voltages being required, however. The centrifugal soot separation can be used particularly advantageously in relatively large stationary internal combustion engines.
Patent DE-3909909-A1 (DE)
Inventor: BEGUN RALPH MURRAY
IPC: G06F12/08
Filed: 1989-03-25
Abstract: A microcomputer system includes a microprocessor, a cache memroy, and a cache controller all coupled to a local bus. The local bus is coupled to a sytem bus, connecting the remaining system components, through latches. When writing data, the microcomputer can perform a posted write to a unit on the system bus by writing the data into the latches and then, on receipt of a ready signal from the cache controller, continuing its operations without waiting for the data to pas to its destination. A problem arises if the data is posted to a unit with a data width less than that of the microprocessor. In this case, the data should be sent in multiple cycles, but the read signal is generated before the data width of the unit is known and the microprocessor then continues its operations and can not, therefore, transmit the data correctly. To solve this problem, a logic unit is added to monitor the ready signal and the output of a decoder which detects non-cacheable addresses (which are of data width different from the microprocessor data width). If a non-cacheable address is detected, the read signal from the cache controller through the logic unit is withheld from the microprocessor, which now waits to continue processing beyond the write until a ready signal is received from the addressed unit on the system bus.
