Patent DE-3537164-C1 (DE)
Inventor: ROLF HELMUT
IPC: H01R12/58
Filed: 1985-10-18
Granted: 1987-01-08
Abstract: A terminal connection pin for solderless connections comprising a press-fit section which is insertable into a contact through bore of a printed circuit board to provide a solderless electrical and mechanical connection between the terminal connection pin and the contact through bore of the printed circuit board, wherein the terminal connection pin has a generally square cross section with an enlarged press-fit section having a groove extending parallel to its longitudinal axis and providing at least two contact paths in an axial direction which are opposite one another and have a limited flexibility. The terminal connection pin provides excellent holding force, and sufficient contact forces across the length of the contact through bore can be achieved by contouring the outer surfaces of the lateral areas and rear area of the press-fit section, with respect to the groove, in the form of peaks and valleys extending in an axial direction, where the distance between the peaks serving as contact points corresponds to half the thickness of the printed circuit board, and where the peaks of the rear area are aligned with the valleys of the lateral areas and the valleys of the rear area are aligned with the peaks of the lateral areas.

Title: Method of running a four-stroke spark-ignition engine
Inventor: PREUSS AUGUST-WILHELM DR
IPC: F02B75/02
Filed: 1987-05-08
Granted: 1988-08-18
Abstract: Method of running a four-stroke spark-ignition engine with not specially hardened seats for the exhaust valves, using an unleaded carburettor fuel which contains 1 to 100 ppm, preferably 5 to 20 ppm, of ferrocene (bis- pi -cyclopentadienyl iron). Due to the addition of the ferrocene readily soluble in fuel, the exhaust valves are protected from excessive wear even at increased speeds and under more severe running conditions.

Title: Method for evaluating the suitability for reception of the frequency-modulated broadcast transmissions received in an FM broadcast receiver, and circuit arrangement for carrying out the method
Inventor: BRINKHAUS STEFAN
IPC: H04B1/16
Filed: 1987-07-02
Granted: 1988-11-24
Abstract: To evaluate the suitability for reception of a frequency-modulated broadcast transmission in a mobile broadcast receiver, the field strength indicating signal is evaluated. It is applied at the same time to a first high-pass filter (30), the cut-off frequency of which is approximately 1 kHz and which is connected in series with an inverting amplifier (32) which is connected via a rectifier diode (34) to an RC section (36), furthermore to a second high-pass filter (38), the cut-off frequency of which is about 80 kHz and which is connected in series with a further inverting amplifier (40), the output of which is connected to the RC section (36) via a rectifier diode (42), and to a bandpass filter (48), the cut-off frequencies of which are about 8 kHz and about 50 kHz and which is connected in series with a high-gain amplifier (46), the output of which is connected to the RC section (36) via a fullwave rectifier (50). The variable charging voltage occurring across the capacitor (C) of the RC section (36) is a measure of the suitability for reception, which includes multi-path reception, adjacent-channel reception and common-channel reception disturbances. <IMAGE>
Patent DE-3726678-C1 (DE)
Inventor: NELLE GUENTHER DR-ING
IPC: G01D5/36
Filed: 1987-08-11
Granted: 1989-03-09
Abstract: In this device, two parallel incremental tracks (5, 6), which are offset with respect to one another by T/4, of the same incremental period T are arranged on a scale (1) on both sides of a reference marker (7). Along the scale (1), a scanning unit with a scanning plate (2) is conducted which also has an incremental division with the incremental period T, both incremental tracks (5, 6) and the reference marker (7) being scanned with this increment by photodetectors (12, 13, 14) located in one line below one another. Due to the symmetric arrangement of the incremental tracks (5, 6) relative to the reference marker (7), the required relation between the reference pulse (UR, URF) and the counting signals which are obtained from the analog scanning signals of the incremental tracks (5, 6) is retained even when the scanning plate (2) is tilted relative to the scale (Figure 1). <IMAGE>

Title: Sensor for determining pressure and temperature of the air in a vehicle tyre
Inventor: BURKARD JOHANNES DIPL-ING
IPC: G01L19/00
Filed: 1987-08-22
Granted: 1989-02-09
Abstract: A sensor for determining pressure and temperature of the air in vehicle tyres is proposed in order to be able to detect a dangerous drop in pressure or excessive heating at the tyre. For this purpose, semiconductor sensor elements (13, 14) for wireless signal transmission are arranged on an insulating material plate (12) which is arranged in an opening (35), directed towards the interior of the tyre, of the sensor housing (18). The sensor housing (18) is attached here in a corresponding bore (24) on the wheel rim (11). In order to insulate the semiconductor sensor elements (13 and 14) thermally from the rim temperature, according to the invention the sensor housing (18) is provided with a threaded shoulder (23) which projects through the rim bore (24). In addition, a nut (30) is to be screwed onto the threaded shoulder (23) of the sensor housing (18) and is to be rested with an annular shoulder (31) on the other rim side via an insulating material ring (32). Finally, the sensor housing (18) is to be clamped tight with the nut (30) to the rim bore (24) and at the same time thermally insulated (Figure 1) from the wheel rim (11) by the insulating material ring (32). <IMAGE>
Patent DE-3905058-C1 (DE)
Title: Apparatus and process for smelting pig iron and for producing useful gas from fine ore and coal screenings (small coal)
IPC: C21B13/14
Filed: 1989-02-18
Granted: 1990-07-12
Abstract: This invention relates to a process for smelting pig iron and for producing useful gas from fine ore and coal screenings and an apparatus therefor which is composed of three stages. Figure 1 shows this apparatus. The suspension gas heat exchanger with the cyclones 1, 2, and 3 forms the first stage and reduces fine ore 10 to preliminary sponge 9. The second stage is composed of the matched double turbulence chamber 20 and the hot cyclone 22, which stage prepares the reduction gas 11 for the first stage and delivers the fine sponge 23 which the third stage melts to give pig iron. The carbon dioxide 15 is scrubbed out of the exhaust gas 4 of the first stage and the pure gas 16 is obtained in a manner such that it divides into circulation gas 17 and useful gas 18. A gas circulation results which flows through the first and second stages, the volume of reduction gas 11 always remaining constant and, with this, the output of pig iron. If more useful gas 18 is taken off from the circulation it is necessary to supplement the absent portion of the circulation gas 17. This is achieved with carbon dioxide and/or steam with more coal for cracking and for additional heating. This invention makes sintering and coking superfluous and controls the gas production in desired ranges. For the reasons stated, it is economically superior to the blast furnace. <IMAGE>
Patent DE-3907229-C1 (DE)
IPC: B60J7/12
Filed: 1989-03-07
Granted: 1990-04-26
Abstract: Partial stiffening of a folding-top covering of a folding top of a convertible vehicle is provided by a wide-shaped elastically stretchable tension-belt element 9 which is stretched between two supporting structure members 2, 3 of the folding top and which extends underneath the stretched covering and bears supportively thereagainst. So that the tension- belt element 9 can be used for stiffening a zone of the covering curved transversely relative to its longitudinal extension, it is supported by contoured shackles 10, 11, so that the wide side of the tension-belt element facing the covering has, at two supporting locations at a distance from one another, a width contour matched to the intended transverse curvature of the covering, and the supporting forces are transmitted by means of a prestress directed towards the covering. A protective overlay 12 is sewn and glued to the element 9 to protect the element against wear by the covering support 6, the overlay being stretched before being applied. The element 9 may be formed by interlaced rubber threads (Fig 4). <IMAGE>
