Patent DE-3200160-A1 (DE)
Title: Design for a low-type, preferably two-wheeled, land vehicle driven by muscular force
Inventor: VIERGUTZ WERNER
IPC: B62M1/00
Filed: 1982-01-07
Abstract: The design is changed with respect to the known two-wheel design to the extent that a steerable rear wheel, whose oscillations follow the direction of travel, is steerable by means of a device which completes a change in the direction of travel in the direction of the respective steering lock as a precondition for the possibility, for the purpose of optimising the application of force within the scope of a two-wheeled design, of permitting the vehicle drive to be capable of being effected from a seating position, supported in the back, to act on the front wheel, whilst the steering system which is designed as a rear-wheel steering system acts with the effect that the vehicle is held in its track and in balance, without steering aids, starting from an uninfluenced inertia force of the centrifugal mass, in that the rear wheel to be steered follows the travelling track in an oscillating fashion and thus ensures the progress of a linear travel movement.
Patent DE-3202600-A1 (DE)
Title: Inductive voltage or current limiter
Inventor: WIESNER ERNST ING
IPC: H02H9/02
Filed: 1982-01-27
Abstract: In inductive voltage and current limiters which have at least one iron core (1) and at least one wire winding (2) it is required that their characteristic can be set and influenced within relatively wide limits so that originally sinusoidal characteristics can be converted in the extreme case as far as a rectangular waveform. This is possible on the one hand by the selection of special material properties, ferromagnetic materials of high remanence and/or high coercive force with a very low permeability being selected, or, on the other hand, by design measures in that expediently the part of the iron core having the high remanence and/or the high coercive force is dimensioned to be so small in the direction of the magnetic magnetomotive force that the magnetic gap produced determines the effective impedance of the inductance. <IMAGE>

Title: Method for the rapid erection of rolls delivered horizontally in the axial direction on a transport belt and device for implementing the method
Inventor: LANGHAMMER HEINRICH ING GRAD
IPC: B65G47/252
Filed: 1982-08-31
Abstract: The present invention relates to a method for the rapid erection of rolls of wound web material delivered horizontally in the axial direction on a transport belt, and to a device for implementing this method. The invention teaches that the device consists of two belts, the first of which is the transport belt, on which the horizontal rolls of paper are delivered, and the second of which is an upper belt with a gripping surface arranged above the transport belt which is driven by two drive shafts and whose lower side sags down to the rolls, the speed of the upper belt being different from that of the transport belt. The method according to the invention is to erect the rolls by tipping them about one of their lower edges, and this is achieved by making the lower side of the upper belt grab one of the upper edges of the rolls, which are erected because of the greater rotational speed of the upper belt.

Title: Circuit arrangement for automatic offset voltage correction
Inventor: KUEHNEL CLAUS
IPC: G06G7/24
Filed: 1982-10-04
Abstract: The invention relates to a circuit arrangement for automatic offset voltage correction. The object of the invention is to improve the exposure accuracy by designing a circuit which ensures that the exposure measurement voltage to be processed by a downstream exposure control circuit is free of any offset voltage component irrespective of the long-term, temperature and operating voltage response of an operational amplifier which forms a logarithm. According to the invention, a subtracting amplifier is used, which is connected via its output to an exposure control circuit, one input of which subtracting amplifier is supplied with the output voltage of the operational amplifier together with an additive component of the offset voltage and the other input of which subtracting amplifier is supplied with the offset voltage which is written into a memory. <IMAGE>
Patent DE-3236978-A1 (DE)
Title: Cutter knives having chopping zones and emulsifying zones for butchery requirements.
Inventor: STIMPFL CHRISTOPH
IPC: B02C18/20
Filed: 1982-10-06
Abstract: The cutter knives are used in cutters of a useful capacity of from 50 to 750 litres in the butchery trade and meat industry. This results in large differences in the size of the knives, which are, however, always shaped in the same proportions. By means of the invention, the handling of the cutter knives is not made more difficult, but the operational safety is increased. Many trials have confirmed the commercial applicability, since sausagemeat production costs are reduced by up to 40%, and this with substantially improved sausagemeat quality. The specific knowledge and feeling of a skilled worker is no longer decisive for the sausagemeat quality. Finally, knife breakages are avoided, which frequently cause severe to fatal injuries.
