Patent DE-3114561-A1 (DE)
Title: Device and method for avoiding collisions in ground transportation
Inventor: HAEFNER KLAUS PROF DR
IPC: G08G1/16
Filed: 1981-04-10
Abstract: The invention has the object of significantly reducing the risk of collision in ground transportation by continuously determining the distance to the other moving vehicles and their speed vectors. As a result, prompt warnings of risks of collisions can be given in the vehicle. The system detects a possible risk of collision by means of a computer from the speed vector of the vehicle and the optically measured movements of other vehicles. The optical measuring process constitutes a sequential viewing on the basis of an observation of light intensities in two batteries by tubes which are arranged in a star shape and have a narrow aperture. The time-dependent intensity distributions are evaluated by means of a computer and permit the necessary speed and distance determinations to be made.

Patent DE-3118618-A1 (DE)
Title: Method and circuit for measuring the time interval between first and second, in particular aperiodic signals
Inventor: WEISSER WERNER ING GRAD
IPC: G01R29/02
Filed: 1981-05-11
Abstract: In a method for measuring the time interval between first and second, in particular aperiodic signals, a clock generator with an adjustable delay time is started up when a threshold value and the instantaneous voltage of the first signal are identical on the leading or trailing edge of the latter and, at the end of the clock generator delay time, the second signal is sampled and its instantaneous voltage stored in a first or second memory depending on whether the clock generator was activated on the leading or the trailing edge. The difference between the stored instantaneous values in the first and second memory is used to control the delay time of the clock generator, which delay time in the steady-state condition is a measure of the time interval between the first and second signal.
Patent DE-3129253-A1 (DE)
Title: Hinged cover for openings in motor vehicle bodies or the like
Inventor: HOELZER EBERHARD
IPC: B60K15/05
Filed: 1981-07-24
Abstract: The invention relates to a hinged cover for openings in motor vehicle bodies, which contain, for example, a tank filler neck. The spring covers are mounted on the vehicle body by means of a hinge plate. The spring force against which the hinged cover can be lifted from its closed position into an opened position and vice versa is produced by a tongue-shaped sprung part (33) of the hinge plate (31). In order to guarantee its ability to function even at extremely high temperatures or to prevent premature fatigue of this sprung part of the hinge plate, the invention proposes to elastically join the tongue-shaped sprung part (33) of the hinge plate (31) to laterally adjacent, essentially rigid parts (41) of the hinge plate (31) by at least one spring steel element (51) arranged parallel to the axis of rotation (17) of the hinged cover (10). The spring steel element (51) reinforces or supports the sprung plastic part (33) without adversely affecting the flat construction of the hinge plate (31). Passenger vehicles are the main sphere of application of the invention. <IMAGE>

Patent DE-3135379-A1 (DE)
Title: Through-passage barrier for doors, staircases and the like
Inventor: BAUER HELMUTH
IPC: E06B9/01
Filed: 1981-09-07
Abstract: The invention provides a through-passage barrier, in particular for protecting children, for doors, staircases and the like. Two lateral, vertical delimiting uprights (4) are provided, between which there is arranged a panel (6) which, by means of lateral grooves (8), is in sliding engagement with sliding guide plates (7) which are welded to the delimiting uprights (4). Each sliding guide plate (7) has at least one spreading slot (11) which runs steeply downwards and diverges downwards, in an oblique manner, away from the associated delimiting upright (4). With each of the spreading slots (11) there engages a spreading pin (15) which runs through the groove (8) of the panel (6) and, on pressing the panel (6) downwards, forces the two delimiting uprights (4) apart laterally and braces them against the side delimitations, here the vertical profiles (2) of a door case, which are fixed to the building. The engagement between the spreading slots (11) and the spreading pins (15) is designed in a self-locking manner. In contrast to the prior art, secure bracing of the delimiting uprights (4) is obtained with respect to the side delimitations, fixed to the building, if the distance therebetween is not constant, it being possible for this to play an important role, for example, when shifting the through-passage barrier from one door case to the other. <IMAGE>
Patent DE-3139743-A1 (DE)
Title: Desk, in particular for office work
Inventor: WAIBEL WALTER
IPC: A47B17/00
Filed: 1981-10-06
Abstract: Transverse frames (7) and longitudinal frames (9) arranged between them are glued on the underside of the work top (1) of a desk on both sides. The longitudinal frames (9) are symmetrical to the longitudinal centre line of the work top (1), but arranged offset inwards from the edge regions of the work top (1) and have guide grooves (9a) for the engagement of bearing elements (19) on the top side of fitted bottom cabinets (18). The fitted bottom cabinets (18) can be displaced laterally in the guide grooves (9a) up to the stop on a vertical limb (7b) of the transverse frame (7) and fixed with their laterally outer wall (18a) to a cross bar (20) which extends between two upright support feet (5) of a support bar (4). The support feet (5) are held with upper fixing portions (6) at the ends of the transverse frames (7). In this manner, an extremely sturdy combination results with a multiplicity of variation possibilities and an attractive visual appearance and functionally appropriate construction of the desk. If no fitted bottom cabinet (18) is provided on one side of the desk, its reinforcement function can be taken over by a bracing device (24) which can be fixed in the guide grooves (9a) of the longitudinal frames (9) and to the cross bar (20) in a corresponding manner like a fitted bottom cabinet arranged there and thus reinforces the angle between the work top (1) and the lateral support bar (4). If the support bar (4) is removed on one side, bearing of the desk can also take place via a holding angle on a shelf wall or the like. <IMAGE>
