Title: Master cylinder for a motor vehicle brake system
Inventor: HAYN HOLGER VON
IPC: B60T17/22
Filed: 1988-05-25
Abstract: A master cylinder has a divided pushrod piston (2) and a directional control switch (11). For actuating the said switch the pushrod piston carries a switch ramp (9), which for setting the assembly preloading according to a setting standard (E) in the housing (1) is positioned relative to a reference point (B) on the housing (1). Between the two parts (15, 16) of the pushrod piston (2) the setting elements (17) are inserted, this setting or the insertion of the setting elements having no influence on the position of the switch ramp (9). In most cases, readjustment of the directional control switch (11) for determining its response or switch-over point is thereby unnecessary.   <IMAGE>

Title: Gas burner
Inventor: JANNEMANN THEO DIPL PHYS
IPC: F23D14/34
Filed: 1988-09-17
Abstract: The gas burner consists essentially of a mixer 12, an adjoining, conical transition piece 13, on which is built a cylindrical burner casing 5 which is closed off at the top by a burner cover 6 and has passage openings 4. Clamped in between the burner cover 6 and the transition piece 13 is a throttling cylinder 1 which is filled by the hyperstoichiometric gas mixture at excess pressure.

The throttle openings 2 lie in a plurality of circular rows 3 one above the other in such a way that they are each located on a vertical line. Situated opposite these lines are vertical, non-perforated sections 7b of the burner casing 5, so that the mixture jets from the throttle openings 2 do not directly strike the passage openings 4. The cylinder 1 is provided at a coaxial distance of 5 mm from the burner casing 5. <IMAGE>

Title: Impact-protection device for motor-vehicle occupants
Inventor: STELZER HEINZ
IPC: B60R21/16
Filed: 1988-10-05
Abstract: A description is given of an impact-protection device (1) for motor-vehicle occupants, in the case of which two gas-inflatable air bags (7a, 8a) are provided on a steering wheel (2). Each of these air bags (7a, 8a) is assigned to a housing half (3a) of a gas generator (3) fastened on the steering-wheel hub (2a). By virtue of different quantities of propellants (5, 6) within the gas generator (3), the air bags (7a, 8a) fill in different, short periods of time and with different internal pressures, with simultaneous triggering of the propellant (5, 6). The air bag (7a) with a high internal pressure is located within the air bag (8a). Consequently, the outer air bag (8a) between the steering wheel (2) and the inner air bag (7a) is largely stabilised in its position against being forced away laterally. <IMAGE>

Title: Underpart of a pivoting table which can be fixed to a vertical surface
Inventor: STEENKEN BERNHARD
IPC: A47B5/00
Filed: 1988-12-03
Abstract: The invention relates to an underpart of a pivoting table which can be fixed to a vertical surface, on which underpart a table top can be arranged and which has a supporting profile with fastening means for fastening it to the vertical surface and to permit the supporting profile to pivot about a vertical axis and which in the region of its free end has a mounting element for mounting the table top. The object of the invention is, therefore, to further develop an underpart of the said generic type such that the table top which can be mounted on said underpart can be brought into the position desired by the user in as individual a manner as possible. The object has been achieved according to the invention by an underpart which is distinguished by an intermediate region between the mounting element for the table top and the actual supporting profile, and which is constructed double-jointedly with mutually parallel, vertical axes.
Patent DE-3842316-A1 (DE)
Title: Self-monitoring start-up circuit for electrical loads
Inventor: LIESKE MARTIN ING GRAD
IPC: G05B9/02
Filed: 1988-12-16
Abstract: A circuit arrangement of timers, the first timer being variable within predetermined limits (start-up time). Within this time, a capacitor C1 of an intrinsically safe timer is charged. After the passage of the first time the pause time begins, exclusively determined by the capacitor charge and the relay data. This pause time is monitored by a second intrinsically safe timer. The operating condition is initiated only after the activation of this last-named timer. Simultaneous switching on or overlapping of the start-up protection and of the operating protection is thus reliably prevented, even in the case of possible defects such as interruptions or short circuit of the components.

Patent DE-3900800-A1 (DE)
Title: Opposed-piston internal combustion engine
Inventor: KLUG ELMAR
IPC: F02B33/22
Filed: 1989-01-13
Abstract: To avoid troublesome vibrations, as for instance those which occur in standard Otto engines, the new internal combustion engine operates on the opposed-piston principle. The opposed pistons produce complete mass balancing, giving absolutely smooth running of the engine. Moreover, the pre-compression piston and the two-stroke timing eliminate the need for unnecessary and fault-prone timing mechanisms such as valves and cam shafts. As a result, higher reliability and efficiency of the internal combustion engine is achieved. By virtue of the spherical combustion chambers and the controlled diaphragm in the fresh-air duct, combustion can be optimised in all engine-speed and load ranges, thereby reducing pollutant emissions to the minimum. The main application will be to use the engine to drive passenger vehicles and lorries or commercial vehicles.

Filed: 1989-02-07
Abstract: A method and a peeling machine (10) are described, in which, to prevent damage to the peeling knife (30, 32), the surface of the log (12) is continuously examined during the peeling operation for the presence of metal inclusions (83) in the interior of the log. This is performed by scanning the surface of the log (12) along one generating line thereof by means of a searching probe arrangement (62), so that the regions of the surface of the log (12) which come into engagement with the peeling knife (30, 32) are in each case examined in layers before the regions reach the peeling knife (30, 32). <IMAGE>
