Patent DE-3100483-A1 (DE)
Title: Supplementary flashing system for motor vehicles
Inventor: UENALDILAR SOEZERI
IPC: B60Q1/30
Filed: 1981-01-09
Abstract: This invention provides the innovation that, as well as the brake lights which are already commercially available, additional hazard flashing light systems or travel direction indicators are attached in the rear window of motor vehicles. These additional hazard flashing lights and travel direction indicators are connected to the upper brake lights (on the rear window) with a supplementary cable. As a result it is ensured that the traffic travelling behind can detect promptly, and above all earlier than previously, the changed direction of the vehicle in front. Also, when there is a risk that the conventional flashing lights which are attached at a low point on the vehicle may become soiled, it is ensured that the flashing lights attached to the interior of the rear window can be clearly seen by the traffic travelling behind and perceived so that as a result a considerable reduction in the risk of accidents can be achieved.

Patent DE-3200505-A1 (DE)
Title: Anchorage for a strand of steel wire as reinforcing element for concrete
IPC: E04C5/12
Filed: 1982-01-11
Abstract: The strand end is bent approximately in the form of an approximately U-shaped hook (3) having two approximately mutually parallel legs (3a, 3b) and a curved joining piece (3c), the axis of symmetry S-S of the hook (3) running obliquely with respect to the strand axis L and the hook (3) passing, via a region (4) of opposite curvature, into the adjoining part of the strand (1). Consequently, a simple and economical alternative to a wedge anchorage is provided, which has the added advantage that a large part of the force to be anchored is transmitted to the concrete already in the region (4) of opposite curvature, having a larger radius of curvature than the joining piece (3c) of the hook (3), so that the region of the hook (3) in which the smaller radius of curvature of the joining piece begins is then subjected to only a small part of the load. <IMAGE>

Title: DC motor without a commutator
Inventor: SCHAUB GERHARD DIPL ING
IPC: H02P6/22
Filed: 1982-03-15
Abstract: The invention relates to a DC motor without a commutator, having a permanent magnet rotor and a stationary multi-pole armature winding with a plurality of winding strands which are staggered uniformly around the circumference and can be connected to a DC voltage source via a digital drive circuit which provides position control of the rotor. According to the invention, in order to ensure that the motor moves as quickly as possible into the desired position-control operation, said drive circuit has a first comparator circuit which, once the DC voltage source has initially been connected to a first winding strand of the motor, tests whether, after this, the position signal occurs which is expected in the correct rotation direction and is derived from the voltages induced in the motor and, if this is the case, applies current to the winding strand adjacent to the first winding strand in the desired rotation direction. Otherwise, a second comparator circuit uses the received position signal to test the angle sector in which the rotor is located, after a predetermined time. After this, it connects the winding strand which has accelerated in the desired rotation direction to the supply voltage, current being applied to the winding strand which is adjacent to the first winding strand in the desired rotation direction in the absence of a signal which can be evaluated. <IMAGE>

Title: Photographic camera having an exposure control device
Inventor: ENGELSMANN DIETER
IPC: G03B7/081
Filed: 1982-07-29
Abstract: A photographic camera has an exposure control device which contains a single magnet. The magnet controls both the exposure time and the camera aperture as a function of a signal of a light-dependent measuring circuit. A shutter element has a prescribed opening which can be moved past the shutter aperture. A trigger can be used both to close the exposure measuring circuit and actuate a drive part. The drive part releases a single armature lever in a preparatory fashion and subsequently activates the shutter element. The single armature lever interacts with lugs on the shutter element and the aperture element. Both can be moved jointly from an initial position into a working position. The shutter element and the aperture element cover their openings reciprocally in a light-tight fashion in each case, before and after the formation of the exposure period, by interacting with the armature lever. <IMAGE>
