Title: Method for transferring motifs from a motif carrier to a substrate
Inventor: ALBIEZ ERWIN
IPC: G03G7/00
Filed: 1984-07-11
Abstract: In the course of the transfer method, the motif is detached from the motif carrier by overlaying and transferred to the substrate by way of wetting the substrate with a dye-dissolving liquid and subsequently laying the motif carrier, with the side containing the motif to be transferred, onto the wetted face of the substrate, pressing it onto the latter and then peeling it from the substrate. The dye-dissolving liquid can be a solvent, which is neutral, nonalkaline and does not contain any ionogenic surfactants or oils and/or hydrocarbons. The invention is characterised in that the motif carrier containing the motif to be transferred onto the substrate is produced as a photocopy of an original according to the electrostatic thermographic copying process using dry toner and heat-fixing.

Title: Cold pilger rolling process
Inventor: SCHAFFRIN ALFRED
IPC: B21B21/06
Filed: 1984-08-31
Abstract: The invention relates to a process for the section-by-section rolling of elongate workpieces on a cold pilger rolling mill with a reciprocating roll stand and a synchronously operating rotation and feed device for the starting workpiece. The proposal is to feed the workpiece forwards cyclically as usual but to operate the rotation device continuously. Such a method of operation is possible within certain boundary conditions because the workpiece obviously undergoes a certain elastic torsion and a torsional slip occurs in the region of engagement of the work rolls.

Patent DE-3438184-A1 (DE)
Title: Device for measuring rotational speeds
Inventor: SCHWARZ KARL-HANS DIPL ING
IPC: G01C19/72
Filed: 1984-10-18
Abstract: In a ring resonator (50), a laser (52) couples in two counterrotating component light bundles which are essentially in resonance with the ring resonator. The component light bundles are brought into interference with the reference light bundles. The interfering bundles each impinge on a detector (84, 86). In the event of the occurrence of a rotational speed, the phase shift occurring in the two component bundles due to deviation from the resonance is observed, e.g. as a change in the intensities of the interfering light bundles. The component light bundles are preferably phase-modulated by phase modulators (88, 90), and the optical phase differences caused by rotations are converted by control loops into electrical phases. An output signal proportional to the rotational speed is obtained from the control loops. <IMAGE>

Patent DE-3447329-A1 (DE)
Title: Diaphragm valve
Inventor: LASER WOLFGANG
IPC: F16K7/12
Filed: 1984-12-24
Abstract: In a diaphragm valve for aggressive media, the shut-off diaphragm of which consists of a sealing diaphragm resistant to the medium flowing through, in particular one composed of PTFE, and of a supporting diaphragm supporting the latter and composed of elastomeric material, and which is clamped by a fixing rim between the bottom part and the top part of the housing of the diaphragm valve, there is a problem which has an unfavourable influence on the life of the diaphragm in that, in particular, the inward-directed tensile force gradually widens the holes in the sealing diaphragm and thus makes the diaphragm leaky. According to the invention, this problem is remedied by the fact that a part of the sealing diaphragm which projects beyond the diameter of the supporting diaphragm forms the fixing rim of the shut-off diaphragm, which is clamped by virtue of force and by positive engagement between the bottom part of the housing and a clamping ring arranged on the top part of the housing.
