Patent DE-3144159-A1 (DE)
Title: Universal amplification circuit
Inventor: GOERTH JOACHIM PROF DIPL ING
IPC: H03F1/08
Filed: 1981-11-06
Abstract: The universal amplification circuit is a universally applicable amplification circuit similar to the operational amplifier, but requiring no external negative feedback in order to adjust the amplification factor. The amplification factor is determined via an internal resistance ratio and the operating voltage. The bandwidth obtainable with the normal bipolar process ranges from zero to above 20 MHz, the transit frequency to over 2 GHz. Due to the absence of external negative feedback, this bandwidth can be exploited with no stability problems. The dependence of the amplification factor on the operating voltage permits use as a control amplifier. The internal structure of the basic circuit consists according to Fig. 1 of a differential amplifier T1, T2, with signal output coupling via a current mirror circuit T3, T4 of vertical pnp-transistors with a free collector connected to the load resistance R1. R2 sets the working point. In the standard setting, the initial open-circuit voltage Uao = UB/2. <IMAGE>

Title: Exhaust gas purification device
Inventor: AOI KATASHI
IPC: F01N3/038
Filed: 1982-04-06
Abstract: The present invention relates to an exhaust gas device for a vehicle engine. The device has a cylindrical housing, through one end of which the exhaust gas is introduced and through the other end of which the exhaust gas is discharged again. The housing contains at least one restriction block lying transversely to the longitudinal direction of the housing and having restriction bores. The exhaust gas flowing through the restriction apertures expands and, in the process, is cooled, with the result that part of the exhaust gas is liquified and small solids particles and small water droplets form relatively coarse particles or exhaust-gas products. These exhaust-gas products are collected by retention means situated in the housing. Finally, the device contains purification means, which are integrated into the retention means, allowing the exhaust-gas products collected by the retention means to be removed from them and sucked off.

Title: Sheet-metal V-belt pulley of welded construction
Inventor: SCHULZE MANFRED DIPL ING
IPC: F16H55/44
Filed: 1982-08-27
Abstract: The invention relates to a sheet-metal V-belt pulley of welded construction for transmitting torque on engines, machines and motor vehicles, in particular in agricultural and general machine construction. Its object is to allow a number of different uses, to achieve as great as possible a relief of the weld seam and to allow rapid replacement in the event of wear on the flank or hub of the V-belt pulley. According to the invention, the object is achieved by virtue of the fact that specific forming into a cup shape or bending into a S-shape or shaping in some other way is used to give profiled carrier elements which are joined so snugly together by means of pressure that a wedge-shaped groove is formed for accommodating the V belt, their mutually parallel abutting faces being firmly connected to one another by spot welding underneath the deformation which arises, and mounted on the hub with a clearance fit and fastened to the collar of the latter by means of releasable connection elements. Multi-groove V-belt pulleys can be produced by arranging a plurality of single-groove V-belt pulleys next to one another.

Title: Method and hollow body for producing a sliding guide between two components which move relative to one another
Inventor: JACOBS HELMUT
IPC: E06B3/267
Filed: 1983-09-22
Abstract: The invention relates to a sliding guide for two components (2, 3) which can be displaced with respect to one another, which guide requires no treatment of the sliding surfaces. Both components (2, 3) are initially produced as an integral hollow body (1), the components (2, 3) being held together by wall sections (4) which can be removed later. The cavity thus formed is filled with plastic, primarily in the form of thermosetting polyurethane, which is then allowed to cure. After this, the wall sections (4) are removed. The plastic shrinks during curing, engaging like a claw in a positively locking manner on the component (3) as a consequence of shrinking head strips (4), while play (16) is formed, in contrast, on the other component (2) as a consequence of the domed wall surfaces (11, 13). After this, the component (2) can be displaced with respect to the component (3) and the plastic body (15). <IMAGE>
