Patent DE-3020720-A1 (DE)
Title: Servo-assisted braking system for motor vehicle - uses hydraulic path simulator for making pedal pressure proportional to pedal travel
Inventor: STEFFES HELMUT
IPC: B60T8/44
Filed: 1980-05-31
Abstract: When the brake pedal is depressed it moves a control rod inside a piston to a point where pressurised hydraulic fluid passes up the bore of the rod through control openings. This fluid enters the end chamber of the assembly and then passes to the brake cylinder circuits on the wheels. At the same time the piston moves in the same direction as the rod. The piston movement compresses oil in a chamber and also sets, through an extension, the travel and operating pressure of a relief valve connected to the compression chamber. The greater the pedal travel the higher the relief pressure becomes thus appearing to simulate the braking effort required on the pedal. The resetting springs for piston and rod have relatively light forces and play no significant part in simulating breaking effort. If hydraulic power is lost the compressed oil from the compression chamber can provide some braking effort on the wheel cylinders.

Title: Tar-bitumen road surfacing binder - contg. a thermoplastic polymeric modifier contg. gps. to render it compatible with the tar-bitumen mixt.
Inventor: BACH HANS VAN DEN
IPC: C08L95/00
Filed: 1980-10-02
Abstract: Binder compsn. comprises (a) coal tar, (b) bitumen and (c) a thermoplastic polymer contg. elements from the lower periods of gps. V, VI and VII of the periodic system or gps. contg. one or more of these elements and/or aromatic gps. contg. these elements or gps., such that the total number of these gps. w.r.t. the number of C atoms in the polymer chain is chosen to make the thermoplastic polymer wll compatible with the tar/bitumen mixt. Typical polymers contain O, N, S, P, F, Cl and/or Br atoms or gps. such as OH, carbonyl, carboxyl, alkoxy, CN, -NH-CO-, hydrosulphide, sulphochloride and/or sulphonic acid gps. The aromatic gps. may be phenyl or polynuclear aromatic gps. Specific polymers are e.g. copolymers of ethylene with vinyl esters and/or acrylic cpd. esp. EVA with a melt index of 1-100; and thermoplastic rubbers such as copolymers of a monovinylaromatic cpd. and an alkaldiene.

The thermoplastic-modified binders provide a strong bond for the chippings, do not soften unduly at high temps. and become brittle at low temps., have good mechanical strength and are resistant to oil, weathering, petrol, salt, etc.
Patent DE-3042694-A1 (DE)
Inventor: BERNEY JEAN-CLAUDE
IPC: G04C3/14
Filed: 1980-11-12
Abstract: The device comprises a stepper motor (20, 21, 22) controlling, through intermediate wheelwork, a wheel (23) carrying at least one soft-iron cam (24) of triangular shape. On each wheel revolution, this cam passes in front of a fixed permanent magnet (25) which exerts a force of attraction on the cam. In a first phase, the attraction acts in the direction of motion of the wheel (23), this being equivalent to a reduction in the load of the motor, hence to a reduction in the time taken by the rotor (20) to perform its step. Then, when the cam moves past the magnet, the attraction acts in the direction opposite to the rotation of the wheel, this tending to increase the time taken by the rotor to perform its step. An electronic circuit detects these variations in duration of the steps of the rotor and delivers information characterising the position of the cam with respect to the magnet. <IMAGE>

Title: Shutter time control device for a photographic camera having a flash unit
Inventor: KILLGUSS HEINRICH
IPC: G03B15/04
Filed: 1981-03-27
Abstract: Provided on a photographic camera are a plug-in mount (3) for flash lamps (6), a blade shutter (1) and a lever (2) which is mounted swivellably and slideably on an elongated hole (2c). A first arm (2a) of the lever (2) projects into the plug-in mount (3), and when the flash lamp (6) is lacking a projection (2e) of a second arm (2b) limits the extent to which the blade shutter (1) can swing out in order to form a shorter shutter time. Arranged directly adjacent to the projection (2e) is a rigid stop (5a) which limits the motion of the lever (2) when the blade shutter (1) stops against the projection (2e) during its action. The projection (2e), the rigid stop (5a) and the elongated hole (2c) are located on a common, essentially straight line, with the result that when the blade shutter (1, 1a) is stopped the lever (2) and its projection (2e) are subjected neither to a noticeable elastic deformation nor to a movement caused by tolerances, bearing play or torque. Highly constant shutter times are achieved in this way. <IMAGE>

Title: Contact arrangement in automatic firing systems
Inventor: VERLAGE OTTO
IPC: F41J5/04
Filed: 1981-06-30
Abstract: As an extension to Patent Application (P 2935527.9), where the bullet briefly connects current-conducting rings which are arranged in an insulated manner one behind the other, during the impact, in order to evaluate the shot, the contact arrangement is hereby applied for as a patent. Normally, in the case of this system, two rings are required for evaluation of a ring number which has been shot. One ring is in this case live and the other ring passes on this control pulse to the electronics after being briefly connected by the bullet. This construction is not suitable, particularly in the case of small designs (air guns). As a result of the new contact arrangement, only one ring is required per ring number. While the first ring carries voltage B, voltage A is applied to the third ring. The ring which is in each case located in between supplies both control pulses to the electronics when it is connected by the bullet. In consequence, one ring has in each case been saved, improved service life is ensured and a display is ensured which is resistant to short-circuits. This contact arrangement is illustrated in the drawing. <IMAGE>

Title: Process for the production of fibre nonwoven
IPC: D04H1/492
Filed: 1981-08-19
Abstract: A process for the treatment of a nonwoven with water nozzle jets is disclosed. A water-impermeable part is used as the supporting part for the nonwoven during the water-jet treatment. The nonwoven is treated on a plurality of water-impermeable rollers arranged in a multi-stage and parallel manner, in order to achieve an effective drainage and effective felting of the fibres after these have been treated on a water-impermeable band, in order to provide necessary strength for further transport to the said rollers. The fibre nonwoven produced by this process has essentially no orifices, and the fibres are tangled and securely felted in a three-dimensional direction.
