Patent DE-3124899-A1 (DE)
Title: Safety brake light system for motor vehicles
Inventor: QUAAS JUERGEN DIPL ING
IPC: B60Q1/44
Filed: 1981-06-25
Abstract: The invention relates to brake light systems in motor vehicles. It indicates the possibilities of improving, by means of an additional device in the vehicle, the properties of the brake light systems currently in use, in particular with the use of additional brake lights. An increase in traffic safety is the objective of these improvements which can be described by three properties:   1) elimination of the technical deficiencies with regard to safety of the brake light systems currently in use; 2) elimination of the deficiencies and irritations of additional brake light systems; 3) the braking process is made clearer to traffic travelling behind by the use of additional brake lights as a hazard indicator and thus permits rapid and reliable reaction. The method of operation of the device is mainly characterised in that   1) the main brake lights light up even if the vehicle is braked heavily in some way but the foot brake is not actuated, 2) the additional brake lights first light up with an initially reduced brightness when heavy braking occurs and then light up completely in the event of dangerous braking. The automatic triggering of the brake lights is determined here by the deceleration (= negative acceleration) of the vehicle. Since the fierce controversy surrounding the general introduction or prohibition of additional brake lights centres mainly on their technical inadequacies, this invention provides a realistic possibility of coming to a satisfactory agreement for all involved. a

Title: Predominantly non-locking hydraulic single wheel brake system for wheeled vehicles of all types
Inventor: BECKER EWALD DIPL ING
IPC: B60T8/40
Filed: 1981-08-19
Abstract: In contrast to conventional brake systems a small high-pressure pump is here flange mounted directly on the brake anchor plate. The pump is operated by an eccentric, which is turned by a friction wheel, which can be pressed against the brake surface. A small servo piston, which is connected to a master piston on the brake pedal, serves for applying the pressure. The contact pressure in drastic braking is only approximately 1.5 bar. Brake fluid or air can be used as control medium. Any servo assistance is dispensed with. The unit functions entirely without electrical components. All lines carrying high pressure are bores or rigid pipes. the contact pressure of the friction wheel is proportional to the pressure on the brake pedal and thereby also to the high pressure generated for the brake cylinder. Once the required brake pressure is attained, the friction wheel begins to slide on the brake surface. A leakage restrictor allows brake fluid to flow back to the intake side. The braking effect declines steadily only below a delivery rate corresponding to approximately 10km/h. Braking to a halt is rendered possible by additional blocking of the restrictor outflow. <IMAGE>

Title: Braking device for the draw-off of winding material from stock rolls
Inventor: REICHWEIN BERNHARD
IPC: B65H23/06
Filed: 1981-10-30
Abstract: In a braking device for the draw-off of winding material in the form of webs, strands or the like from stock rolls, a braking disc is connected fixedly in terms of rotation to the stock roll locatable as a function of the draw-off. It is located between a stationary end plate and a non-corotatable pressure plate spring-loaded axially towards the latter. To design the device so as to be space-saving and, at the same time, use it as a holding brake, it is proposed additionally to arrange on the plate side of the pressure plate located opposite the braking disc a non-corotatable thrust plate which has passages for the spring loads acting on the pressure plate in the manner of a slipping brake. The thrust plate is itself equipped with its own strong axial springing which loads the thrust plate towards the pressure plate and which, in the effective position, activates the thereby loaded pressure plate as a holding brake. However, the thrust plate is equipped at the same time with a restoring device which is directed counter to its axial springing and which normally keeps the thrust plate in ineffective ventilation contact with the pressure plate, but if required can be cut out.
