Title: Straightening die for round stock - has stock passed through die and simultaneously rotated longitudinally and deflected in straightening arc
Inventor: BOCK ERWIN
IPC: B21C19/00
Filed: 1980-05-30
Abstract: Round drawn material is straightened by passing it through straightening dies and at the same time rotating it about its longitudinal axis. The material is temporarily deflected in a straightening arc so that the yield point of the material is exceeded. To prevent the stress relief produced giving rise to a change in dimensions of the feedstock, the surface of the material is subjected to frictional forces acting along the direction of its longitudinal axis. It has at least one pair of driving discs (2,2) and rotatably supported straightener dies (6,7,10) in close succession one behind the other along one or more straightening arcs. These have an alignment in the longitudinal direction, so that material passing through the dies is subjected to frictional forces acting along the direction of its longitudinal axis.

Title: Hinge with a device for damping the closing movement of doors or the like, especially of fire doors
Inventor: SLOGSNAT UDO
IPC: E05F3/20
Filed: 1981-05-05
Abstract: In a hinge with a device for damping the closing movement of doors or the like, especially of fire doors, with at least one pivotable door-hinge sleeve and fixed frame-hinge sleeves, there is provided a tubular hinge pin which passes jointly through all the sleeves and is connected fixedly in terms of rotation to a door-hinge sleeve and in which is firmly inserted axis-parallel a piston strip provided with overflow bores (?) which, in the event of a rotational movement, slides the pin in a corresponding fixed counter-bearing by means of a front, preferably cylindrical strip portion. By means of this counter-bearing, two axis-parallel pressure spaces are formed in the pin. In the remaining angular sector of the closing movement, a recess in the cylindrical strip portion takes effect and makes a virtually non-throttled connection between the two pressure spaces. In such a construction according to the invention, no movement deflection is necessary for damping in the closing direction. The damping occurs as a result of the fact that the hinge-pin interior is divided into two pressure chambers by the piston strip and the counter-strip. These chambers vary during the pin movement.

Title: Method for converting a band-limited 16-QAM signal into an 8-QAM signal for the purpose of carrier recovery
Inventor: BESSAI HORST DIPL ING
IPC: H04L27/38
Filed: 1981-09-10
Abstract: In the conversion of a band-limited 16-QAM signal into an 8-QAM signal, it is necessary to blank the middle amplitude level out of the 16-QAM signal. According to the invention, this is done firstly by approximating the envelope of the 16-QAM signal (35 MHz) to a square-wave signal by supplying the third (105 MHz) and fifth (175 MHZ) harmonics. The middle amplitude level is discriminated from the square-wave signal by the comparator using adjustable thresholds and corresponding logic combination. Thereafter, a 16-QAM signal is superimposed on the output signal of the comparator. The middle amplitude level thus receives a boosted average DC voltage. An overproportionally high downstream amplification of the middle amplitude level suppresses the remaining two amplitude levels. Finally, the compensation signal thus obtained is combined in antiphase with the input signal, and the middle amplitude level is thereby eliminated. <IMAGE>

Title: Arrangement on a combustion engine, especially for motor vehicles
Inventor: UTILI CLODOVEO
IPC: F02M21/02
Filed: 1981-10-26
Abstract: A combustion engine which can be operated either with liquefied gaseous or with liquid hydrocarbons as fuel and in which air and hydrocarbons are introduced separately from one another into the combustion chambers of the engine when operating with liquid hydrocarbons (injection system) has a reducing evaporator for operation with liquefied gaseous hydrocarbons, which is connected by way of a gas line to a device for producing a gas-air mixture, a so-called mixer, preconnected to the throttle valve. The engine also has a back pressure valve for closing the air intake line. For starting the engine and for maintaining the idling speed when the suction exerted by the engine is not sufficient to open the back pressure valve far enough, an additional gas feed line (20) with a nozzle (21) directly into the intake pipe (18) of the engine is provided below the throttle valve. As a result a quantity of gas sufficient for idling is fed uniformly to the engine even when the back pressure valve is fully or partially closed. <IMAGE>
