Patent DE-3631463-A1 (DE)
Title: Pressure-retaining valve
Inventor: BURGDORF JOCHEN
IPC: B60T11/34
Filed: 1986-09-16
Abstract: A pressure-retaining valve of a simple type of construction is proposed which essentially consists of three components: housing (1), piston (4), sealing part (3). The simple type of construction is achieved by the piston (4) being of two-piece design and having a stepped bore. The axially bored sealing part (3) can therefore reach through the narrower bore of the piston so that the springs (20, 23) belonging to the piston and the valve-closing part can be supported directly on the housing via an annular disc (21). The annular disc at the same time forms the inlet-side stop of the piston (4). Although as a component the annular disc (21) belongs to the piston (4), it forms a functional unit with the sealing part (3). <IMAGE>

Title: Oscillating link for vehicles
Inventor: KIRSCHNER JOCHEM DIPL ING
IPC: F16F1/387
Filed: 1987-03-06
Abstract: The invention relates to an oscillating link (9) for vehicles for arrangement in a multi-link axle, especially for the rear wheel suspension, comprising two metal-to-rubber bearings (18, 19), the bushings (10, 11) of which are connected to one another, fixing elements being insertable through the bearing cores (12, 13) of the bearings in order to connect these to the body and a trailing link. The object of the present invention is to create an oscillating link of the said type which has a short geometrically active length, while ensuring favourable load distribution in the bearings. According to the invention, it is proposed, in the case of an oscillating link of the said type, to connect the bushings (10, 11) directly to one another and to arrange the respective bearing axis (14) of the bearing cores (12, 13) eccentrically to the centre axis (15) of the respective bushing (10, 11) in the direction of the other bushing (11, 10). <IMAGE>

Title: Door-locking system
Inventor: SMIRRA KARL
IPC: E05B53/00
Filed: 1987-03-07
Abstract: In a door-locking system, especially for a helicopter door with a locking element (4) pretensioned into the blocking position and with at least two actuating elements (6, 8), remote from one another and from the locking element, for the mutually independent unlocking of the door, according to the invention there is provided, instead of a linkage, between the locking element and actuating elements a single pretensioned pull rope (22), of which the engagement points (30, 50) of the actuating elements are located one behind the other in the longitudinal direction of the rope and are designed in such a way that the pull rope, whilst maintaining a tension, increased during the unlocking of the door, over the entire effective rope length, can be adjusted in the unlocking direction of the door by means of each individual actuating element, with the result that a constructively very simple, functionally reliable and, above all, light-weight design of the door-locking system is achieved, the said design being protected against disturbing rattling movements. <IMAGE>

Title: Stope support for pneumatic stowing
Inventor: PAWELSKI LUDWIG
IPC: E21F15/08
Filed: 1987-03-21
Abstract: A stope support suitable for pneumatic stowing and having a backward-projecting roof member and a follow-up pneumatic-stowing line as well as a stowing wall supporting the stowing remains readily accessible and nevertheless protected against stowing running in, since the individual sections of the stowing wall can be extended as far as the floor. They can be stabilised and reliably guided in the region of the floor via guiding drag runners and actuating cylinders and in the upper region by the displacement cylinders, in such a way that the stowing face is held reliably in each case until the blowing of the next blowing field, specifically even below the natural slope angle, so as to obtain an advantageously closely packed stowing which cannot slip. In the longitudinal direction of the longwall, the sections of the stowing wall overlap one another, so as to obtain an advantageously continuous supporting surface, behind which, in relation to the coal face, the blowing pipeline and the specially designed blowing-pipe couplings as well as the straightening, lifting, bracing and adjusting cylinders are accommodated in a protected manner. As a result of the stabilised stowing wall, there is no need for closable hatch plates and screening plates on the actual stope. The construction is thereby simplified substantially. <IMAGE>

Title: Method for detecting moving targets by means of an optronic (electrooptic) image recording device (camera)
Inventor: ROHLING HERMANN DR RER NAT
IPC: G01V8/10
Filed: 1987-04-15
Abstract: It is proposed for an optronic image recording device to produce and store an expected value, in the form of pixels, from successive values of the same pixel in time by recursive mean value formation and to produce and store a type of background image from the totality of pixels in this way. Each new brightness value for a pixel is compared with a threshold value which is derived from the expected value stored for this pixel. Only measurements which exceed the threshold value are interpreted as target reports and are passed onto downstream processing devices.

Filed: 1987-05-04
Abstract: In the case of the known optical storage discs, an information track is in each case assigned a neighbouring intermediate area as a guide track. This area cannot be used for the storage of information. Between two neighbouring guide tracks (32) there is in each case arranged an information area (35), which is suitable for receiving a plurality of mutually parallel information tracks (36). A guide track (32) may consequently be assigned in each case a plurality of closely neighbouring information tracks. By this measure, the storage density of optical information storage discs can be increased. Optical information storage discs. <IMAGE>
Patent DE-3726956-A1 (DE)
Title: Coating composition
Inventor: KRUEGER ALFRED
IPC: C09D133/04
Filed: 1987-08-13
Abstract: The known coating compositions based on hydroxyl group-containing acrylate resins or copolymers and/or hydroxyl group-containing polyesters and wholly or partially etherified amino resins and/or their carboxyl group-containing derivatives, are improved by containing urea and/dicyandiamide. It is also possible to use homogenous mixtures or solutions of urea and/or dicyandiamide with etherified amino resins. Instead of the acrylate resins or copolymers and/or polyesters, it is also possible to use the reaction products of these compounds with urea and/or dicyandiamide, which should be understood as low molecular weight precursors of urethane resins or as solid or liquid solutions of urea and/or dicyandiamide. The excellent properties of coatings produced from the coating compositions according to the invention are attributed to the isocyanate-free formation of polyurethanes in the film.

Patent DE-3734595-A1 (DE)
Title: Plug connection for electrical cables
Inventor: SCHEKALLA PETER
IPC: H01R13/28
Filed: 1987-10-13
Abstract: Until now, contact elements have been used in the coupling halves, which contact elements have in their engagement region male longitudinal folded parts on one side and female longitudinal folded parts on the other side, which parts form contact zones parallel to the axis. This necessitates a specific rotational position of the mating contact element with respect to the contact element. In addition, the longitudinal folded parts which engage over one another stick to one another and are mutually deformed. It is proposed to arrange all the contact zones in axial planes which intersect on the centre axis. Apex angles (which are located diametrically opposite with respect to the centre axis) of angle regions which are enclosed between two axial planes are designed to be identical to one another. Finally, the individual longitudinally folded parts of the contact element are arranged only in every other angle region. For making contact with electrical cables, especially in the field of motor vehicles.

Title: Combined apparatus for improved vegetation conditions and long-term tending of earth-culture plants
Inventor: BLOCK HUBERT K
IPC: A01G27/02
Filed: 1988-02-10
Abstract: Ceramic outer pots are often unsealed and cannot be used for the storage of water. Furthermore, enough importance is often not attached to the necessity of good root aeration. The object is solved by the invention, on the one hand, by providing a water-tight outer pot (1) which forms an annular-space reservoir (10, 14). On the other hand, provision is made, for existing, unsealed outer pots, for a plastic double-walled tank sleeve (11) which forms an annular space reservoir, is flexible in its diameter and is accommodated approximately in the lower third between the outer pot (1) and the clay plant pot (2). A water-level indicator (8) with a supplementary shaft (8<e>, 8<f>) curved in a flat and parallel manner serves as a monitoring and charging element. By a capillary granulate (6) which is introduced in the reservoir and the annular space located thereabove and/or (corresponding to a parallel application) by a lengthening in the clay shaft which runs downwards from the stacking border of the plant pots and stands in the reservoir (10), the entire clay plant pot (2) is permanently moistened and the soil (3) and plant are thus watered. Through-passages (1<b>, 1<c>) on the base side in the special outer pot (1/Fig. 1) ensure a good CO2 exchange and against a negative inversion effect, while maintaining a small plant-pot base trough (1<e>). In variation, a granulate duct (5, 6<a>) is provided in the plant-pot shaft region (on the inside). In each case a draw-off-hole sleeve (7) together with an identical-format earth-viewing element (4) round off the apparatus. <IMAGE>

Title: Device for monitoring the level of a liquid
Inventor: RUETTEL MARTIN DIPL ING
IPC: G01F23/296
Filed: 1988-03-29
Abstract: A piezoelectric oscillator (1) is periodically loaded with a wobble frequency (e.g. from 100 to 120 kHz). In this case, the frequency (f) sweeps across the resonant frequency (fr) of the oscillator (1). The RF-signal (U) fed to the oscillator (1) is tapped off at a bias resistor (54) and fed to differentiating element (59) via a rectifier (56). In the region of the resonant frequency (fr), this output signal (D) contains impressed pulses (see Fig. 3) if the oscillator (1) is not damped. If, on the contrary, the oscillator (1) is immersed in the liquid (44) to be monitored, i.e. the oscillator (1) is damped, the pulses are then missing from the output signal (D) (see Fig. 4). The output signal (D) is preferably fed to a shut-off valve (64) for the liquid (44) via a monostable element (60) used for lengthening the pulses. The device is particularly used for liquid gas monitoring. <IMAGE>

IPC: H03K5/08
Filed: 1988-07-20
Abstract: An output signal of a magnetoelectrical transducer of a capstan DC motor used in a magnetic tape recorder includes a DC offset voltage. The output signal of the transducer is coupled to a non-inverting input of a first operational amplifier. The output signal is also coupled to an inverting input of a second operational amplifier, operating as a comparator. The non-inverting input of the second operational amplifier is coupled to an output terminal of the first operational amplifier that amplifies an AC voltage component of the transducer output signal. By means of two anti-parallel coupled diodes in a negative feedback branch of the first operational amplifier, a DC amplification of unity is obtained as soon as a first peak of the output signal of the transducer is reached.
