Patent DE-3812815-A1 (DE)
Title: Cheek piece, especially for sporting guns
Inventor: FRANK FRANZ
IPC: F41C23/14
Filed: 1988-04-16
Abstract: The cheek piece, which is detachably connected to the gun stock by means of a fastening screw is adjustable vertically and horizontally with the aid of spacers which are loosely inserted into suitable recesses in the gun stock and the cheek piece. Each spacer consists of a lower cylindrical element and an upper cylindrical element which is screwed by means of a threaded stud into a vertical threaded hole in the lower element. The vertical position of the cheek piece with respect to the gun stock can be varied by screwing the upper element in or out. The threaded hole in the lower element is arranged eccentrically with respect to its longitudinal centre axis. The horizontal position of the cheek piece can be varied, independently of the vertical position, by rotating the lower element.

Title: Process and set of structural elements for producing a cavity floor
Inventor: REIS SIEGFRIED
IPC: E04F15/024
Filed: 1988-11-30
Abstract: For the simple, adaptable and inexpensive production of a cavity floor, individual, stable spacer blocks having mutually parallel, planar upper-side and underside bearing surfaces are arranged, according to the invention, on the underlying surface such that they are distributed over the region of the cavity floor.

Title: Method for controlling a three-point invertor
Inventor: STEINKE JUERGEN DR ING
IPC: H02M7/48
Filed: 1988-12-21
Abstract: A method is put forward for pulse-width modulation control of a three-point invertor. The method is preferably applicable in the case of traction drives in the low-rotational-speed range. A target voltage space vector <IMAGE> defined by a regulating device is used. For forming the switching instants of the invertor valves connected to the terminals or to the mid-point of the intermediate voltage circuit, converter-section phase-voltage target values (easoll1, ebsoll1, ecsoll1, easoll2, ebsoll2, ecsoll2) are intersected by at least partly triangular reference voltages (Uref1, Uref2). The intersection instants represent the switching instants. The amplitude of the reference voltages corresponds to half the theoretically maximum possible output phase voltage. The converter-section phase-voltage target values (easoll1, ebsoll1, ecsoll1, easoll2, ebsoll2, ecsoll2) are formed from the current-voltage target values (easoll, ebsoll, ecsoll). The latter are formed, for each pulse period (TP), by projection of the target voltage space vector <IMAGE>  onto the three stator winding axes (a, b, c). <IMAGE>

Title: Device for saving power in piston compressors, in particular for compressed-air generation in motor vehicles
Inventor: SPURNY DIETER ING GRAD
IPC: F04B49/24
Filed: 1989-03-22
Abstract: In the case of a piston compresser which is regulated by a pressure regulator, it is desired, for the purpose of optimal power saving, to switch the suction valve in the idling phase into an inactive position. For this purpose, the suction lamella (7) of the suction valve is displaced by means of an actuating piston (27), acting on it via a transmission lever (45), from the pumping position into the switched-off position or idling position on the underside of the valve carrier (3), in such a way that the suction orifices (9) of the piston compressor are at least partially open, i.e. are not completely covered by the suction lamella (7). Furthermore, in the idling phase the suction lamella (7) at least partially covers the pressure orifices (11) of the pressure valve of the piston compressor, in order to prevent, in the idling phase, further delivery in the direction of the consumer. In addition, a non-return valve (53), preferably in the form of a non-return lamellar valve, is arranged within the cylinder head (5) between the suction connection (71) of the piston compressor and the valve-carrier plate, carrying the suction valve and the pressure valve, of the piston compressor, said non-return lamellar valve opening in the direction of the suction space (67) and obstructing in the direction of the suction line connected to the suction connection (55; 71). <IMAGE>

Title: Treating combustion gas pollutants in superimposed reaction stages - vertically coupled by guide tubes providing different catalytic reactions
Inventor: STRITTMATTER WINFRIED
IPC: F23J15/02
Filed: 1989-05-02
Abstract: A housing (2) is divided by transverse floors into two or more completely sealed reaction stages (3,4), linked together by catalyser tubes (14) passing through the sepg. floor. Combustion gases charged with a range of solid and gaseous pollutants, e.g. dust, NOX, SO2, SO3, fluorine, chlorine and/or heavy metals have the solid components removed while rising through a layer of adsorbent material, e.g. coke or active carbon, in the tubes, whose walls and contents in the lower reaction stage are charged with catalyst with one or more pollutants, es. SO2. While passing through the following section of catalyser, and after injection of suitable additive, esp. NH3 or urea, in this or a preceding stage, the gases are treated with a catalyst for further pollutants, esp. NOX. Similar sequences may follow in later stages. Fresh catalyst and adsorbent may be added at the heads of the reactor tubes. Finally, treated gas emerges from the vertically uppermost stage. ADVANTAGE -  A range of fume treatments are applied in a single encased unit.
