Patent DE-3310594-A1 (DE)
Title: Motor vehicle with an audible reverse-travel warning system
Inventor: HAGEN WOLFGANG DIPL ING
IPC: B60Q5/00
Filed: 1983-03-23
Abstract: The invention relates to a motor vehicle with an audible reverse-travel warning system, composed of a signal generator and of a sound source. Reverse travel movements can considerably increase the operational risk of a motor vehicle. In some countries, such as for example Australia, it is therefore stipulated that an audible warning should be issued when travelling in reverse in order to catch the attention of passers-by. However, a warning system with its sound signals directed outwards is prohibited in many countries and therefore cannot be used. It is also disadvantageous that the warning signals may be submerged in the noise of road traffic and thus lose their warning effect. Finally, it is also not possible to issue a warning to the driver in the passenger compartment if he has inadvertently selected the reverse gear. According to the invention, these advantages are avoided in that the sound source is arranged in the passenger compartment of the motor vehicle. It is particularly advantageous if the signal generator is constructed as an electronic gong and the sound source is constructed as a loudspeaker.
Patent DE-3312887-A1 (DE)
Title: Overpressure valve for a packaging container
Inventor: BRAUN HARALD
IPC: B65D77/22
Filed: 1983-04-11
Abstract: A film (1) (valve plate) and a covering film (2) are attached to a container wall (W) by bonding or welding. Inserted between the valve plate (1) and the container wall (W) is an elastic filter body (3). Between the films (1) and (2) there is a viscous layer (11). In the case of slight overpressure on the side (12) of the wall (W), the films (1, 2) are pressed apart and gas flows from the inside of the container via the opening (6), the filter body (3), the opening (7) and the openings (8) and (9) into the atmosphere. The filter body (3) prevents particles of the product touching the mutually sealing surfaces of the films (1, 2). The elastic filter body also brings about a reliable upholding of the closed position of the valve. The valve is primarily intended for packaging bags for food and semi-luxury products. <IMAGE>

Title: Solid-state circuit (IC)
Inventor: CLEMENS BERND DIPL ING
IPC: H01L25/16
Filed: 1983-06-09
Abstract: Solid-state circuits (IC) are used on printed-circuit boards and in each case consist of an insulating body (1) on which active and passive components are arranged which form a complete electronic circuit, based on semiconductors, in a very small space (chip 3) and have connecting conductors (4), which are passed to the exterior and are connected to terminal legs (3), and furthermore require a capacitor which is allocated to the solid-state circuit, filters the supply voltage (VCC) and whose connections are connected to the supply voltage and to earth. In such solid-state circuits, voltage surges on the power supply leads, which are caused by current pulses with steep rising edges, are damaging to the components which are used on the chip, for example transistors, diodes and the like. In addition, the remote arrangement of such blocking capacitors leads to disadvantages in the interception of voltage surges. In order to allocate the blocking capacitor with an improved mechanical effect, in a less costly manner in production-engineering terms, and with an improved electronic effect of the solid-state circuit, it is proposed that at least one capacitor (6) be enclosed within the insulating body (1) which supports the active and passive components, and that said capacitor (6) be arranged at the minimum possible distance, in terms of line technology, from the integrated circuit (chip 3). In this case, the capacitor (6) is advantageously fused into the insulating body (1). <IMAGE>

Title: Chain connecting link for round-steel chains
IPC: F16G15/02
Filed: 1983-09-21
Abstract: The chain connecting link consists of two J-shaped link halves (1) which engage in one another and have limb ends (2) which are like hammer heads and in each case engage in a correspondingly formed-out pocket (3) on the opposite longer limb end (4) of the respectively other link half (1) in a positively-locking manner, and are held together in a transverse hole (6) by means of a securing pin (5). The transverse hole (6) and a groove (7) on the opposite limb end run obliquely with respect to the longitudinal symmetry plane (8) of the chain connecting link and, in addition, each of the two J-shaped link halves (1) has, in the region of the longer limb (4) and in the transition region form the shorter limb into the bracket region (11), a material projection (10 or 12 respectively) which expands in the form of a wedge from the outside to the inside, as a result of which on the one hand assembly and dismantling of such chain connecting links with the chains remaining in guides and the like is simplified, and as a result of which, on the other hand, increased fatigue strength and load capability of such chain connecting links also result. <IMAGE>

Title: Inverted-tooth-type-chain cycle with adjustable saddle
Inventor: SIEBKER THOMAS
IPC: B62M1/24
Filed: 1984-03-21
Abstract: Field: mechanics, transport. In a conventional cycle, the force is only fully utilised if the pedal lever is horizontal. In the inverted-tooth-type-chain cycle, on the one hand, unused forces acting counter to the pedal axle are avoided and on the other hand the weight of the leg is utilised. Together with the up-hill saddle, it is superior to a conventional cycle by virtue of the performance and even more so when going up hills.

Title: Locking mechanism for a solar-cell generator which can be unfolded
Inventor: KIENDL HELMUT
IPC: E05D11/10
Filed: 1984-05-17
Abstract: The invention relates to a locking mechanism for panels, which can be unfolded, of solar-cell generators. In this case, a plurality of solar-cell panels are connected to one another by means of hinges. One hinge part of each hinge carries a locking arm which is mounted on a shaft of the hinge part and carries a locking pin at its free end. A semicircular guide track (10) for the locking pin is provided on the other hinge part. During unfolding, the locking pin remains along the guide track, a spring (11) being provided which pulls the locking pin in the direction of the hinge bolt (5) of the hinge. After the end of the pivoting movement, the locking pin latches into a locking slot (H) in the second hinge part (4). In order that the unfolded final position is no longer dependent on the manufacturing tolerances of the elements which are involved in the unfolding and locking, it is proposed according to the invention that the shaft (7) carrying the locking arm (8) have an axis which is eccentric with respect to the locking arm. If the shaft (9) is rotated, then the position of the locking arm changes in consequence. In this way, after completion of the unfolding and locking process, a panel (1) can be adjusted into a final position with respect to the other panel by rotating the shaft (9), in which final position both panels lie in the same plane. <IMAGE>

Patent DE-3432296-A1 (DE)
Title: Rotating threaded tube as a drive and for industrial processes
IPC: F04D3/00
Filed: 1984-09-03
Abstract: The object of this additional application is to convert smooth-walled tubes, which thus are not threaded, in such a way that these too force gases and liquids to flow. This is achieved, on the one hand, by incorporating propeller blades in the tube in order to impose, by means of rotation of the tube about its theoretical longitudinal axis, a flow on the gases and liquids. If funnels or tapering tubes are used, it is possible to compress gases in this simple manner. This compression can be so strong that the compression heat of the emerging gases is sufficient to enable welding, preferably of plastics. Said gases can also have a flow imposed on them by means of a helical thread which is smaller than the diameter of the tube but which is fastened to the tube with tie rods and thus co-rotates therewith. A metal sheet twisted in a corkscrew-like manner or a twisted square piece of metal, a rod, which co-rotate with the tube could likewise force gases and liquids to flow.
