Patent DE-3149099-A1 (DE)
Title: Brush holder for an electrical machine
Inventor: SCHNEIDER THEODOR
IPC: H01R39/38
Filed: 1981-12-11
Abstract: By means of the invention, a brush holder for an electrical machine, having a sleeve holding a carbon brush and having at least one attachment tongue, which projects essentially at right angles to the sleeve axis, is folded as one piece with the sleeve out of a flat material, and can be inserted into a support, is intended to be developed further such that it can be assembled in a simple manner. This is achieved in that the attachment tongue is arranged at a lateral distance from the sleeve and an intermediate piece is inserted between it and the sleeve, from which intermediate piece the attachment tongue projects approximately at right angles. In such a design, the forces which are required for assembly can be introduced into the attachment tongues via the intermediate pieces. In this case, the sleeve is not stressed so that it is no longer necessary to stabilise its shape in a special manner during assembly.

Title: Stand for setting up pole-shaped objects, in particular Christmas trees
Inventor: MEYER JUERGEN DIPL ING
IPC: A47G33/12
Filed: 1982-01-20
Abstract: The stand serves the purpose of guaranteeing that upright objects stand securely, combined with simple handling. The technical problem was to eliminate deficiencies, such as the alignment, the attachment, the considerable effort and the manual skills required, and to gain additional advantages. The solution consists in the fact that an expandable inside part can be pumped up in an outer housing. The expansion of the inside part causes an even, all-round pressure over a large area. As a result, maximum stability, adaptation to irregularities, automatic vertical positioning, coverage of any cross-section, handling by one person, setting-up in a standing position, a simple solution, non-requirement of manual skills, non-requirement of effort, automatic adaptation of the cross-section, even in the case of drying-out (shrinkage) are achieved without effort. The primary use will be the "setting-up" of Christmas trees.

Title: Return-flow injection nozzle for the atomisation of liquids
Inventor: BECKER BERNARD DR ING
IPC: F23D11/38
Filed: 1982-09-22
Abstract: A return-flow injection nozzle comprises a swirl space (2) with tangential liquid feed, a controllable liquid return connected to the swirl space (2) and an injection channel (8) leading out of the swirl space (2). To ensure that the cone angle of the injection cone (9) emerging from the injection channel (8) remains virtually constant irrespective of the particular injection rate, according to the invention the injection channel (8) comprises an elongate, cylindrical or slightly tapered first channel portion (81) and a second channel portion (82) of smaller diameter starting immediately upstream of the outlet. In the first channel portion (81), the angular momentum imparted to the liquid is reduced by friction, the angular momentum being greatly reduced in the case of low injection rates and affected only slightly in the case of high injection rates. In the second channel portion (82), the axial velocity is then increased. Return-flow injection nozzles according to the invention are particularly suitable for the atomisation of liquid fuels in combustion chambers of gas turbines. <IMAGE>

Title: Device for damping rotary and bending vibrations of the crankshaft of an internal combustion engine
Inventor: BOISCH RICHARD DR
IPC: F16C3/06
Filed: 1982-09-24
Abstract: With the crankshaft of a reciprocating-piston internal combustion engine, where rotary and bending vibrations are damped by securing a counterweight elastically on a crank web in order to compensate inertia forces by forming a gap, the splash oil present in the crankcase is used as damping means. Collecting devices collect the splash oil, which, under the action of the centrifugal force, is forced into the gap between those parts of the crank web and the counterweight which are capable of moving relative to one another.

Title: Test filter for the non-invasive testing of the tube high-tension on X-ray apparatuses
Inventor: EDER HEINRICH DR ING
IPC: G21K1/10
Filed: 1982-12-31
Abstract: For rapid, non-invasive testing of the tube high-tension, a test filter is moved into the beam path, which filter consists of two materials having different K-absorption edges and thicknesses, the K-edge of the one material being somewhat below the limiting energy of the X-ray spectrum to be tested. At a specific tube voltage, the two filters show equal transparency to the X-ray radiation, while on the other hand they have different permeability at deviating voltages. In consequence, direct visual evaluation is possible on the test photograph or on the fluorescent screen. A plurality of filter materials with different K-absorption edges can be used for testing a relatively large voltage range. Finally, tolerance bands for the voltage to be tested can be defined by different filter thicknesses.

Patent DE-3313660-A1 (DE)
Title: Flame tube boiler with preheating system for the combustion air
Inventor: WIESER RUDOLF DR
IPC: F22D1/36
Filed: 1983-04-15
Abstract: The invention relates to a flame tube boiler with a hydraulically coupled preheating system for the combustion air. With this system, it is possible to achieve exhaust gas temperatures of 100 DEG C - possibly even 90 DEG C - when using natural gas for firing and thus to save an additional 2 to 3 percent of fuel. If the boiler is fired exclusively using natural gas, the heat exchangers of the preheating system for the combustion air are expediently formed by ribbed tubes, which have a low draught loss on the flue-gas side or combustion-air side and take up less space. If the boiler is fired alternately with natural gas and heavy oil, the primary heat exchanger (that supplied with flue gas) is designed as a double-tube or bare-tube construction (tube coil construction) because of the greater risk of fouling and only the secondary heat exchanger (supplied with combustion air) consists of ribbed tubes. The preheating system for the combustion air can also be designed as a multi-part system, each subsystem of which operates on the heat pipe principle. <IMAGE>
