Title: Appts. for repair welding of the tips of guide vanes and runner blades of turbomachines - incorporating notched jaws with an adjustable gap
Inventor: MERZ JOSEF
IPC: F01D5/00
Filed: 1992-11-03
Abstract: The appts. for repair welding of turbine blades (1) incorporates cooled jaws (2,3) clamping the blade so that the worn blade tip protrudes above the jaws. The appts. is characterised in that the entry and exit edges (A1, A2) of the blade body (5) engage in the respective bearing notches (K1,K2) of the jaws (2,3), with one jaw (2) fixed and the other (3) movable against the blade edge (A2). The notches (K1,K2) are located at the vertices of cutouts in the jaw faces. These cutouts have diverging shape, so that their side surfaces do not contact the blade sides. The fixed jaw (2) carries an adjustable plate (6) forming a stop for the blade end. Such a plate is attachable/releasable by magnetic means. The blade is pressed against the plate (6) by means of a thrust element (7). The jaws (2,3) are made of copper, and are cooled by circulation of a cooling agent (water, for example). USE/ADVANTAGE - For repair of worn turbine blades. The relatively simple appts. enables blades with different geometries to be welded under precisely predeterminable local cooling conditions.

Patent DE-4311663-A1 (DE)
Title: Method and devices for softly switching on filament lamps
Inventor: BROICHER HERIBERT F DR ING
IPC: H01K1/64
Filed: 1993-04-08
Abstract: When filament lamps are cold on switching on, a high current which damages the filament lamp flows for a brief time. Known electronic devices for softly switching on electric apparatuses (appliances) cannot be used economically for normal filament lamps (incandescent lamps). The object of the invention is to provide, with simple components, a cost-effective device for soft switching-on. A bimetallic strip, acting as a switch, utilises the heat emitted by a series resistor to bridge precisely this resistor with delay in terms of time, the heat generated by the filament lamp subsequently defining the switch position. A device of this type is preferably fitted in the cap of the filament lamp itself. Different devices are based on this method. A particularly suitable device comprises a spiral-shaped bimetallic strip, acting as series resistor, which, during heating, rolls off on the inside against the conductive cap of the filament lamp and thereby reduces its effective resistance. The advantages of the method and of the devices reside in the fact that the life of filament lamps is increased with simple means, which, fitted in the filament lamp, require no adaptation on the part of the user. <IMAGE>

Title: Classifying joint parts equipped with ball races
Inventor: KRAMER HORST W DIPL ING
IPC: G01M13/04
Filed: 1994-03-22
Abstract: In a method of classifying ball race-equipped joint parts for assembly of synchronised rotary joints, in order to associate suitable pairings of joint outer and inner parts, the novelty is that (a) the joint part (3a) is held so that it is in an axially defined position w.r.t. its longitudinal axis but is freely movable perpendicularly to this axis in a gauge ring (2); (b) measuring balls (4), which are held in a number of gauge ring apertures (13) corresponding to the number of ball race tracks (6), are seated in the respective races (6) by axial displacement of a measuring cone (10) relative to the gauge ring (2); and (c) the axial position assumed by the measuring cone (10) relative to the gauge ring (2) is used as the reference size for the classification. For classification of an outer part, the balls (4) are caused to seat in the races (6) of the outer part (3a) by outward movement in the apertures (13) resulting from spring-biased axial motion of the cone (10) in the direction towards its smallest diameter. For classification of an inner part, the balls are caused to seat in the races of the inner part by radial inward movement resulting from spring-biased conformal axial motion of the gauge ring and the inner part in the direction towards the smallest diameter of the cone.
