Title: Control and monitoring system for signal train flow - uses incorporated test of memory region state to determine output and input addresses coincidence
Inventor: SCHNABEL HARALD DIPL ING
IPC: H04L25/52
Filed: 1977-08-13
Abstract: The system is intended for telecommunications, in order to process a signal train using a dwelling period in a functional unit. A buffer store receives the individual signals of the train. The functional procedure for the control, monitoring and processing is regulated by a programmable circuit, following a basic cycle in response to decision signals. The occupation of a preset memory region by addresses forms a criterion for at least temporary function termination. The determination of the memory region (XO/70-77) occupation is carried out by at least one test incorporated into the functional cycle. This test also indicates a coincidence of an input (E/74) and output (A/72-A/74) address in a variable region of the memory.

Title: Continuous transfer printing of textiles - using jets of heated air to achieve adequate film-to-fabric pressure
Inventor: MEISEN KLAUS
IPC: B41M5/035
Filed: 1978-08-25
Abstract: In the continuous transfer printing of textiles, partic. where the foundation for the material and the overlying printing film is flat or only slightly rounded, the printing film is pressed into close contact with the material by one or several streams of air directed perpendicularly against the back of the printing film, to give a pressure between film and fabric which is within the range 2-300 mm of water. The air-stream, which may be heated above ambient temperature, issues from rows of jets or from transverse slits between which are exhaust vents by means of which the air is collected for re-circulation. The pressure and the heat content of the streams of air may vary along the length of the plant. The process provides an effective means of applying pressure to an extended flat surface, which can be easily varied to suit the nature of the fabric surface.

Title: Film threader for cassette - has concentric spool shells and self-aligning threading slot
Inventor: GOETZE CHRISTIAN
IPC: G03B27/58
Filed: 1978-10-27
Abstract: The automatic threader for a light proof fikm cassette in which the spool is formed by two concentric shells, one (14) to fit over the driv drive spindle, and the other to rotate about the first one. The space between the shells takes the film leader, via a slot (21) in the outer shell. A pivoted catch (18) at the end of the film guide (6) grips a notch (17) in the outer shell to line up the slot with the film.
