Title: Flash key circuit for the signal-transmitting interruption of a subscriber line in a telephone system with multi-frequency dialling
Inventor: HANNAK GUENTHER ING
IPC: H04M1/53
Filed: 1985-12-05
Abstract: A flash key circuit for the signal-transmitting interruption of a subscriber line in a telephone system with multi-frequency dialling, in which a mechanically operable key (T) and a flash circuit (FK) disposed in series in one wire of the subscriber line are provided, which flash circuit contains a timer (T1, R2, R3) with an RC component (R1, C2) and a bistable relay (F) with a normally-closed contact (f) which normally shorts the flash circuit (FK), a winding (W) of the bistable relay (F) and a series-connected charging capacitor (C1) as an initiation circuit for a signal-transmitting interruption of the subscriber line and, in parallel with this, the timer (T1, R2, R3) with the RC component (R1, C2) and a thyristor (Th) are disposed in the flash circuit (FK); the timer (T1, R2, R3), which responds to a predetermined charging voltage of the capacitor (C2) of the RC component (R1, C2), shorts the flash circuit (FK) at the end of the required subscriber line interruption period by igniting the thyristor (Th) (Fig.1). <IMAGE>
Patent DE-3611556-A1 (DE)
Title: Switched-mode power supply
Inventor: GULCZYNSKI ZDZISLAW
IPC: H02M3/158
Filed: 1986-04-07
Abstract: The invention relates to a switched-mode power supply for connection to DC voltage. The field of use is for highly effective converter power supply units having a high operating frequency, as well as acoustic amplifiers having a high output power. The power supply is distinguished by a low number of components, a short control response time and low RF interference radiation. There is no need to expect any overvoltage spikes or surge currents. The power supply contains at least two switches which are switched independently of one another. The capacitor which is connected to the output of the power supply is charged when the output voltage is insufficient and acts like an energy source when the voltage is too high. If a transformer is used instead of a storage inductor, the mains isolation can be achieved easily. The power supply actually also represents a functional acoustic power amplifier. A version without mains isolation is particularly simple, because an LC delay element, which is connected upstream of the loudspeaker, can be included in the power supply. Just one comparator is sufficient to achieve the quantisation of the input signal. <IMAGE>
Patent DE-3613762-A1 (DE)
Title: Administration device for injectables, especially for instrumental insemination or transfer of embryos
IPC: A61D19/02
Filed: 1986-04-23
Abstract: The invention describes a universal administration device for the administration of injectables, for example animal sperm or embryos for implantation, comprising a cannula and a generally disposable sleeve pulled over the latter and releasably fastened on the proximal end of the cannula via a clamping chuck, especially an eccentric clamping device. The individual design of the sleeve end is not important; the sleeve tapers conically in its interior at the distal end and has on the outside a shaped body which ensures the conical form, on the one hand, and a rounding, on the other hand, the shaped body being applied to the material of the tubing wall. A cutting unit integrated in the device reliably positions the cutting plane correctly on cutting-open of the packages.

Title: Vehicle seat having a longitudinal guide with vertical or tilt adjustment and with a belt lock fastening
Inventor: BAUER HEINZ
IPC: B60R22/26
Filed: 1986-12-11
Abstract: The vehicle seat has, in known fashion, a longitudinal guide (20, 22), a device for vertical or tilt adjustment (24) and a belt lock fastening (32) which is fastened at its lower end region to the seat rail (22) of the longitudinal guide and supports a belt lock (34) at its upper end region. In order to modify the position of the belt lock as little as possible with respect to the sitting surface (30) during adjustment of the sitting surface (30) by means of vertical or tilt adjustment, the belt lock fastening is composed of a lower part (38) which is articulated to the seat rail and an upper part (40) which is articulated to the seat support (26), the said fastening being connected to the belt lock. One part is guided in a freely displaceable manner in a longitudinal guide which is formed by the other part and which may be curved. One part has at least one locking projection (60), while the other part has locking recesses (46) which interact with the latter. The two parts are held in their normal position, which permits free displacement, by means of a securing piece (50), which is, in particular, elastically deformable. In the case of force being exerted on the belt in the event of an accident, the securing piece is made to yield, causing the locking projection to engage in the locking recesses and blocking removal of the upper part from the lower part. <IMAGE>

Title: Amplifying device for unipolar pulse-shaped signals having a duty ratio of less than 0.5
Inventor: RADIUS ROLAND DIPL ING
IPC: G01R31/26
Filed: 1987-11-14
Abstract: Pulses with maximum edge steepness have previously been amplified with the aid of elaborate wideband amplifiers. The novel, very simple amplifier arrangement, in contrast, allows an amplification up to twice the original pulse amplitude to be achieved, the maximum amplified frequency components of the signal being located within the range of the transit frequency of the transistor used. The unipolar pulses of a generator (1) fed in on a radio-frequency line (4) generate a current pulse across the very small input impedence of a transistor (5). At the output end of the transistor (5), a voltage pulse is generated across a load resistor or a second radio-frequency line (6), which pulse has twice the amplitude of the input pulse when the characteristic impedences of the two lines are the same. The reflections on the first line (4) are suppressed by a passive matching network of a diode (2) and a resistor (3). So that the return reflections do not disturb the pulse generation of the generator (1), the duty ratio must be less than 0.5. The amplifying device enables very short pulses with very steep edges, such as occur in wideband communication systems (for example optical fibre transmission links) to be amplified. <IMAGE>

Title: Strut
Inventor: HOPFGARTNER JOHANN DIPL ING
IPC: E21D11/26
Filed: 1988-05-13
Abstract: It was necessary to create a device with the possibility of transmitting force to the support section with minimum stress, single-shear screw connection for coping with eccentric force loading and achieving the absolutely firm screwed condition, identical tubular-bar end suitable for any channel and web sections, saving production costs by avoiding welding, piercing on mandrel and cutting the tubular bar to length, and also operational usability together with struts of the same generic category. Such a strut consists of the tubular bar supported against the support section, a conventional strap bridging the support section and two hook or machine bolts specific to the support section and having nuts. In the exemplary strut for channel section (9.1), the tubular-bar end (12) lies with its raised part in the concave portion of the strap (13) and alternatively has a parabolic punched surface (1), sloping punched surface (2) or bending surface (3). The strut constructed in this way serves as an assembly aid during the placement and serves to protect against shifting during the useful and dismantling phase of the support. <IMAGE>

Title: Method for controlling brushless electric motors and control circuit therefor
Inventor: KOTHE KARL-PETER DIPL ING
IPC: H02P6/15
Filed: 1988-06-04
Abstract: In order to control a brushless D.C. motor (1), use is made of a three-phase driver signal delivered by a rotor position sensor (3) for driving transistors (7) in a transistor bridge circuit (6). The transistor bridge circuit (6) supplies the windings (5a, 5b, 5c) in the stator (4) of the D.C. motor (1) with current pulses. Using a microprocessor control (12') in which the signals delivered by the rotor position sensor (3) for driving the transistors are processed, the commutation point for the transistors (7) is brought forward by a predetermined amount of time which is optionally constant or dependent on the rotational speed. By this precommutation, an increase in the torque is achieved in higher rotational speed ranges of the D.C. motor, independently of the rotational speed. <IMAGE>
