Title: Label printing device - roller for advancing and supporting printed labels coupled with label lifting device
Inventor: FURTWAENGLER WALTER
IPC: B65C9/18
Filed: 1973-07-20
Abstract: A printing device with an arrangement for intermittently advancing a label supporting strip, includes a roller supporting the printed label and fitted with teeth round its circumference engaging perforations in the strip edge to advance the strip. Coupled to the roller is a device by which printed labels are lifted off the supporting strip, consisting of a spring loaded arm in which are mounted three spaced shafts round which the strip is guided to release the printed labels. The position of the arm relative to the roller is adjusted by an eccentric cam and rigid stop in order to equalise dimensional tolerances of the perforated strip in relation to the strip advancing roller.

Title: Automatic telephone trunk dialling system - has cct. transmitting confirmation signals back to exchange form of A.F. signals
Inventor: DIRR JOSEF
IPC: H04Q3/62
Filed: 1973-08-21
Abstract: All elements in long distance traffic controlling connections in the direction from the initiating switching means, or carrying out the counting, contain means which send back all the confirmation signals. These switching means have AF signals evaluators, and further means for regeneration and/or retransmission of these confirmation signals, also serving as audible signals. The confirmation signals which are not used as audible signals are AF marked in the last incoming trunk dialling translation, so that the last generating build-up element transmits them as d.c. signals up to the last translation, where the d.c. criteria are converted into AF signals.

Title: Hot pressure flat shapes from powders, esp. silicon nitride - using graphite die design for uniform temp. distribution
Inventor: APPLIN MICHAEL
IPC: B28B3/02
Filed: 1973-08-30
Abstract: Flat mouldings are mfd. from powders or granules using hot pressing, esp. the prodn. of Si3N4 or other ceramic compacts. The heating is applied solely by the punches in the die, and in such a way that a uniform temp. is obtd. over the entire cross-section of the compact. Heating is pref. applied by graphite elements located in cavities in graphite punches, using graphite plates of high thermal conductivity, and contg. cavities, on both sides of the compact for better heat-distribution; plates of loose graphite felt are also used between the graphite punches and the punches on press. The uniform temp. obtd. by this process produces uniform mechanical properties right across the cross-section of the compacts.
