Patent DE-4304212-A1 (DE)
Inventor: LAPPE KURT
IPC: B44C1/17
Filed: 1993-02-12
Abstract: A transfer sheet for printing a substrate comprises a base film (1), a detachable release layer (2) arranged thereunder, a varnish layer (3) of a transluscent structure, a preferably vapour-deposited metal layer (4) arranged thereunder and also an external layer facing away from the base film (1).

To provide a sheet for printing a substrate which is easier to process than known embossing foils, it is proposed to form the external layer as a sealant (5) which does not have any adhesiveness of its own. Only in combination with an adhesive, which itself is not a component part of the transfer sheet, does the sealant (5) cause the transfer sheet to be bonded to the substrate to be printed.

Title: Diameter and profile pick-up (sensing device, probe)
Inventor: RIETH MICHAEL
IPC: G01B11/08
Filed: 1993-02-27
Abstract: The invention relates to a diameter and profile pick-up whose measuring device consists of a laser light source which emits a highly parallel, ribbonlike light beam of predetermined height and thickness of ribbon. A detector is aligned on the laser light source. An object to be measured (sample, test specimen) is located in the ribbonlike beam and partially shades (occludes) the latter. The remaining beam intensity is detected and assigned to the sample diameter or to its surface roughness. Apart from the specimen, the beam path possibly also includes windows, transparent to the laser light, of a possibly required, hermetically sealable processing room.   Depending on the measurement task, the specimen is guided through the laser beam, or the measuring device is guided parallel to the axis of the specimen. The entire test stand is constructed from commercially available components.

Title: Power supply device for operating a DC gas-discharge lamp
Inventor: REINEFELD ARNO
IPC: H05B41/392
Filed: 1993-05-17
Abstract: The known power supply devices for DC gas-discharge lamps are not able to provide the lamp, in all possible operating states, with the operating parameters, prescribed by the manufacturer, with high precision. The novel power supply device is intended to maintain the required operating parameters with high precision under all conditions and thereby to achieve for the lamps the longest possible service life and an emission which is as constant as possible. The problem is solved in essence in that the operating parameters of the lamp are constantly measured by suitable devices (2), (3) and (4), and in that a power supply unit (6) is controlled by linear and non-linear processing of these measured values in the devices (4) and (5) in such a way that the operating parameters correspond precisely to the preset specifications. The power supply device is particularly suitable for supplying DC gas-discharge lamps and other loads which require a specific characteristic which cannot be generated by conventional power supply units. <IMAGE>

Title: Process for plasma coating solid substrates by means of a gas capable of deposition
Inventor: SOEDER BERNHARD DR
IPC: H01J37/32
Filed: 1993-10-22
Abstract: For plasma coating, a solid substrate and a flowing gas capable of deposition are exposed to a plasma in a plasma flame space and the gas is conveyed to the substrate at such a flow rate that its residence time from entering the plasma flame space to impinging on the substrate lies in the range of the deposition maximum. The deposition of a layer from the gas activated in the plasma goes through a strongly pronounced maximum, which is known as the deposition maximum, at a certain, narrowly delimited residence time in the plasma flame space.
