Title: Brake booster
Inventor: MUELLER KARL-HEINZ DR
IPC: B60T13/14
Filed: 1986-07-11
Abstract: In a brake booster for a motor vehicle brake system with wheel slip control, a housing (1) defines a pressure chamber (2), into which a housing bore opens, which receives a booster piston (28) which actuates a brake master cylinder piston. A pushrod (26), which can be actuated by foot pressure and acts on the booster piston (28), passes through the wall of the pressure chamber forming a seal. Hydraulic fluid can be admitted into the pressure chamber (2) by way of a control valve (3) as a function of the position of the pushrod (26) and the booster piston (28) until such time as the pressure in the pressure chamber (2) has a value proportional to the actuating foot pressure, which value extends by way of a brake circuit connection aperture (33) in the pressure chamber wall. In order to simplify the construction and the manufacture of the control valve (3), it has two rotary slide valves (4, 5), bearing on one another with plane-ground surfaces (6, 7), with valve openings (11 to 14), which overlap one another as a function of the angle of rotation of the rotary slide valves. <IMAGE>

Title: Injection pump for internal combustion engines with acceleration-controlled injection timing (BAS) especially in vehicle engines
Inventor: HAAS ECKHARD DIPL ING
IPC: F02D1/18
Filed: 1986-12-16
Abstract: A fuel injection pump for internal combustion engines with acceleration-controlled injection timing (BAS) is proposed. The pressure in the injection pump internal chamber (1') is lowered in the event of sudden acceleration, thereby producing a "retarding" adjustment of the injection pump. During acceleration, the piston-spring system (15, 18 and 19) inside the timing device (9) is moved by operation of the pedal (24) by way of the linkages (21, 22 and 23), and with the pin (16) strikes the ball (10) against the force of the spring (12), so that the fuel flows out of the internal chamber (1') by way of the throttle bore (8) into the return (3). The order of magnitude of the required retarding adjustment can be individually fixed by the cross-section of the throttle bore (8). In the case of slow acceleration, fuel escapes by way of the bore (17), so that the non-return valve (13) does not open. On reaching the 3/4 load limit, the connection bore (6) is covered by the piston (15), so that the timing device is rendered inoperative (Fig. 1). <IMAGE>

Title: Method for stabilising the frequency of a laser diode independently of the diode current
Inventor: ABOU-ZEID AHMED DIPL PHYS DR
IPC: H01S5/0683
Filed: 1987-03-02
Abstract: A method for stabilising the frequency of a laser diode, in which the temperature of the housing (12) of the laser diode (8) is measured and is kept constant for heat supply or dissipation. When the current which is required to operate the laser diode (8) is switched on, the current intensity is slowly increased from an initial value to a required value. The actual temperature (12) of the housing of the laser diode (8) is changed as a function of the current intensity supplied to the laser diode (8), in such a manner that the laser diode (8) emits light at a constant wavelength at any desired current intensity. The temperature control of the laser diode (8) is carried out in accordanc with the current intensity, by means of a stabilisation factor  alpha  = d lambda /(di)/d lambda /(dT). The method is also used in the event of voltage or temperature fluctuations after reaching the operating conditions of the laser diode (8). <IMAGE>

Title: Heat exchanger designed as a shell-type cooler
Inventor: STEFFEN FRANZ-JOSEF
IPC: F28F9/007
Filed: 1987-12-11
Abstract: Shell-type coolers are used, for example, on air-cooled internal combustion engines for recooling the oil. In particular in the case of cold oil, the shell-type cooler is subjected to a high pressure loading. The novel design of the shell-type cooler is intended to provide selected reinforcement of the areas of the cooler which are at risk. In order to prevent expansion at the corner regions of the shell-type cooler (1, 30), supporting shells (6, 7, 33, 4, 35) are inserted between the shell segments (4, 43). The supporting shells are advantageously adapted to the shape of the shell segments. <IMAGE>

Patent DE-3903889-A1 (DE)
Inventor: MARK FRITZ
IPC: B23B51/00
Filed: 1989-02-10
Abstract: The drilling device for making undercut drill holes in subsoil has a guide sleeve (2) and an eccentric bush (4) rotatable relative to the guide sleeve. A torsion spring (6) is arranged between the guide sleeve (2) and the eccentric bush (4). When the eccentric bush (4) rotates relative to the guide bush (2), the torsion spring (6) is tensioned. As a result, the drive shaft (8) with the cutting head (9) is at the same time put into an eccentric position and a recess is produced in the wall of the drill hole. In the process, a locking mechanism acting on a tooth system (2a) prevents the guide sleeve (2) from rotating with the eccentric bush (4). Once the maximum eccentricity of the drive shaft (8) is reached, the locking mechanism is released and the guide sleeve (2) is rotated together with the eccentric bush (4) via an eccentric drive. As a result, the cutting head (9) creates an encircling undercut in the wall of the drill hole. After a complete revolution, the torsion spring (6) can be relieved again and the guide sleeve (2) can rotate relative to the eccentric bush (4) so that the drive shaft (8) again moves into the concentric position.
