Title: Facades of rubber profile networks - with vulcanisation by sprayed intersections(AT 15.1.81)
Inventor: DEUTSCH HEINZ
IPC: E04F13/08
Filed: 1980-11-24
Abstract: Facades or other linings are made with networks of rubber profiles for sealing glass panes and panels which are produced by vulcanisation of injection moulded cross, T or K-shaped sections. The vulcanisation of the network is achieved by direct spraying of the intersections on the prefabricated profiles so that the network is mounted on the building site as a whole This eliminates the vulcanisation at the building site and makes the operations independent of the weather. The direct spraying of intersections on the profiles results in good strength of all butt joints. The vulcanisation is completed with a plus tolerance so that on the building site the profile must be compressed and no undue reductions of cross sectional area are enforced by attempts to stretch the lining.

Patent DE-3123670-A1 (DE)
Title: Friction false twister
Inventor: BAUER KARL DR ING
IPC: D02G1/08
Filed: 1981-06-15
Abstract: A friction false twister consists of two discs moved relative to one another in the overlap region and having parallel or slightly staggered axes of rotation. The discs are so arranged with their axles in mountings that the distance between the two discs and/or their position in relation to the yarn running through between them is variable. The discs form a twisting region on the side facing the yarn running through. For this, at least one of the two discs is movable in a cardanic manner on its axle, in that it consists, for example of a flexible or pliable, but tension-resistant material. A pressing-down device serves for ensuring a good yarn contact. As a result of the geometrical positioning of the pressing-down device, on the one hand, and of the disc mountings, on the other hand, in relation to one another and by the adjustment of other operating parameters, such as the yarn, rotational speed of the discs and pressing force of the pressing-down device, the best possible operating conditions, including the twisting direction, can be set.

Title: Movable device for removing ferromagnetic particles
Inventor: BAERMANN HORST
IPC: A47L13/41
Filed: 1981-07-30
Abstract: In the case of a movable device for removing ferromagnetic particles, which is provided with two or four running wheels (2), one or more magnetic strips (4) are arranged inside the casing (1) transverse to the direction of movement. The magnetic strip is composed of a permanent-magnetic strip (5, 13) or of individual permanent magnets (12) which are arranged at intervals and are magnetised in such a way that the pole faces exhibit a north pole and a south pole. To the two pole faces (6) there are fastened iron pole shoes (7), the pole faces (9) of which are situated at a short distance from the ground (10). The pole shoes (7) between adjacent permanent magnets (12) have deflections (14, 15), causing the polar distances on the pole faces (9) of the pole shoes respectively to increase or decrease in a continuous manner. To permit removal of the collected material (16), a profiled rail (8) made of a nonmagnetic material is arranged beneath the magnetic strip (4) so as to be movable with respect to the latter. An actuating device causes either the profile rail (8) to be lowered towards the ground (10) or the magnetic strip (4) to be raised so that the profile rail is no longer acted upon by the magnetic field, causing the collected material to fall off. <IMAGE>

Title: Method and device for producing concrete shapes using a motor-driven unbalance-type vibrator
Inventor: PAPPERS RUDOLF
IPC: B06B1/16
Filed: 1981-10-06
Abstract: The invention relates to an unbalance-type vibrator. Vibrators of this kind with a sinusoidal vibration characteristic are known. However, optimum density of the energy to be introduced into the vibrated material is not achieved with a sinusoidal vibration. It is the object of the invention to provide an unbalance-type vibrator which releases a considerably higher vibration energy to the vibrated material per unit time. This is achieved by virtue of the fact that the unbalance components (6, 9) are arranged around a common axis (34) of rotation and have different amplitudes and frequencies, the resulting vibration pattern having a non-sinusoidal characteristic. Fig. 1 shows the unbalance-type vibrator (1) with its housing (2), which, at its ends, has the bearings (3 and 4) in which the outer unbalanced-weight shaft (5) with the unbalance weight (6) secured on it is rotatably mounted. The outer unbalanced-weight shaft (5) is designed as a hollow shaft in which the inner unbalanced-weight shaft (10) with the unbalance weight (9), designed as an eccentric, is rotatably mounted via the bearings (11 and 12). On the left-hand side, the V-belt or toothed-belt pulley (13) is firmly connected to the outer unbalanced-weight shaft (5). On the other side, the V-belt or toothed-belt pulley (14) is firmly connected to the end of the inner unbalanced-weight shaft (10). <IMAGE>

IPC: B62J99/00
Filed: 1981-11-25
Abstract: System for signalling a change in driving direction for a vehicle in which the driving direction indicator is automatically switched off by the steering device of the vehicle when the latter is moved back to a predetermined position. The system can be used in particular on motorbikes. It contains a sensor which is realised as a potentiometer (6) and generates a signal which represents a steering movement angle which corresponds to the actuation of the steering device of the vehicle, and an interference signal suppression circuit (A) which receives the signal of the sensor and eliminates interference portions which are contained in the signal as a function of the travel speed of the vehicle. The peak value holding circuit (B) receives the output signal of the interference signal suppression circuit (A) and holds the peak value of the signal. A comparator (C) receives both the output signal of the interference signal suppression circuit (A) and the output signal of the peak value holding circuit (B) and compares these signals with one another in order to bring about a clearing signal for the driving direction indicator when the steering device has been moved back by a predetermined amount in the direction of its normal position. <IMAGE>
