Title: Method of dimming fluorescent lamp in secondary circuit of transformer
Inventor: BIRK BERTHOLD
IPC: H05B41/38
Filed: 1997-04-24
Granted: 1998-07-30
Abstract: A procedure for dimming a fluorescent lamp located in the secondary circuit of a transformer has the primary side of the transformer controlled with pulse sequences of adjustable duration in push-pull. An oscillatory circuit containing the fluorescent lamp before the beginning of each pulse sequence is temporarily set into oscillation to ionise the lamp gas so that lighting of the lamp is securely prevented.  After ionisation, the conventional forced control of the fluorescent lamp takes place. The transformer is controlled by single impulses which can be varied with regard to number and/or frequency and/or amplitude as well as the DC component.

Title: Plastic pipe cutting machine parting e.g. lengths of corrugated cable wiring duct and slitting it for use in automobiles
Inventor: ZINKL WOLFGANG
IPC: B26D3/16
Filed: 1997-12-18
Granted: 1999-05-20
Abstract: Cylindrical passage (4) in the body (5) of this cutting machine, guides the pipe. Rings (7, 8) concentric with the pipe carry a guide unit for the knife (6). When the rings are rotated relative to each other, the knife is advanced into the pipe, cutting into its wall. Drive is reversed to retract the knife. Cylindrical passage (4) in the body (5) of this cutting machine, guides the pipe. Rings (7, 8) concentric with the pipe carry a guide unit for the knife (6). When the rings are rotated relative to each other, the knife is advanced into the pipe, cutting into its wall. This relative rotation is achieved by accelerating the second ring (8), as the first freewheels. The rings are then coupled in rotation to complete cutting around the pipe. Drive is reversed to retract the knife, allowing the pipe to be advanced for the next cut. An Independent claim is also included for the corresponding pipe cutting equipment. Preferred Features: The guide unit has a holder (9) to which the knife is detachably fastened. This holder pivots on the first ring (7), to make the cut, controlled by a sliding linkage cam on the second. The pipe has corrugations (22, 24). Projections (23) parallel to the knife and moving with it, limit the depth of cut and control its location. The knife is aligned by the projections to cut only the corrugation peak. In a development, the pipe is longitudinally slitted, driving with the central mandrel (18) and internal drive wheel (20). The equipment is further detailed. The rotors run on ball bearings. Knife cutting angle lies at approximately 80 deg  to the pipe surface tangent, at the point of cutting (6).
