Title: Jet loom weft channel - is structured by blades so that shed size is reduced to lower moving mass
Inventor: SCHEFFEL WALTER
IPC: D03D47/30
Filed: 1978-06-12
Abstract: The weft guide for a jet loom is formed by blades with flow outlets, and solid blades. The channel is vertically tapered from the reed plane with a bowed closure, and enclosed by a web of the blade at the blade side, up to the weft outlet gap. The blades forming the narrowest cross section of the weft channel have upper and lower shell surfaces parallel to the yarn plane of the closed shed when the sley is in the insertion position, so that the channel narrows between two blades with flow outlets. The arrangement of the blades is such that the channel expands in a step formation after a flow outlet in the blade. Each flow outlet is placed near the web on the blade side and is aligned so that outlet flow downstream has an increasing gap from the reed, tapering towards the main axis of the weft channel, with a flow axis which does not intersect with the shell surfaces on each side of the channel. The design allows the size of the shed to be reduced, so that there is a reduced moving mass which allows higher weaving speeds.
Patent DE-2838979-A1 (DE)
Title: Gas pressure measuring device - passes sound signal through measurement path and its velocity is measured
Inventor: THOMA ANDREAS DIPL PHYS DR
IPC: G01L11/04
Filed: 1978-09-07
Abstract: The device can be used for altimeters, speedometers and climb indicators. A sound signal from a transmitter is passed through a measurement path to a receiver. Its velocity of propagation and attenuation are determined by the pressure of gas in the path, and evaluated by an evaluation device. Dependence of the usual pressure measurement methods on temp. is eliminated, since variations of the signal velocity of propagation are compensated by corresponding variations of the gas density and sound absorption. Thus an unambiguous correspondence between sound velocity or attenuation and pressure is achieved.

IPC: H04B17/40
Filed: 1979-10-19
Abstract: 1. A process for address-free (symbolic) fault location by means of a loop closure in a communication transmission link for the transmission of digital communication signals from a locating end station via at least one intermediate regenerator which regenerates and/or amplifies the transmission signals in both directions of transmission and which contains a loop closure switch which serves to connect the output of the regenerator for one direction of transmission to the input of the regenerator for the opposite direction and further contains a change-over switch which connects the input of the regenerator of the opposite direction to the connected loop or to the ouptut of the transmission link of the opposite direction, wherein the locating end station transmits one single locating signal during the entire fault locating process, characterized in that commencing from the operating state, the locating signal transmitted periodically contains a code of short duration, that following a recognition time (T1) all the intermediate regenerators which receive this locating signal assume a preparation state in which a state counter (ZZ) is released and these intermediate regenerators emit a locating signal which has been modified in such a manner that the code which is still contained therein can no longer be recognised as a code by a receiving intermediate regenerator and the latter remains in the equalizer control zone and in the synchronisation zone of the phase control loop, that the intermediate regenerators which have been switched into the preparation state and which receive the modified locating signal switch back to the operating state following a hold time which corresponds approximately to the recognition time (T1), and that at the end of the hold time, in the event of an interruption in the transmission of the locating signal for a step-on time (T2) which is short in comparison to the recognition- and hold time, the intermediate regenerator which has remained in the preparation state is switched into the loop closure state and the input of the regenerator for the opposite direction is cut off from its preceding signal path, and in addition the unchanged locating signal is transmitted to the intermediate regenerator which follows in the locating direction, the state counter (ZZ) is switched on, and the switched loop closure is retained for the duration of the unmodified locating signal, which exceeds the recognition time (T1), that in the event of a further change in the locating signal for the step-on time (T2) the state counter (ZZ) in the intermediate regenerator with loop closure is switched into an end position, the loop closure in this intermediate regenerator is discontinued, and the locating signal is transmitted with its code unchanged to the intermediate regenerator with follows in the locating direction and this intermediate regenerator is switched into the loop closure state.
