Title: Knitted tights made on machine with oscillated cylinder - using auxiliary jacks moved by switchable cams into idling track
Inventor: BONO RENATO
IPC: D04B9/46
Filed: 1978-01-19
Abstract: During predetermined working phases in the operation of a circular knitting machine, the end needles of an arc of needles, are put separately and consecutively out of action and/or are again brought back into action. The needles put out of action being brought into a lowered position of rest. Whilst the needles are being put out of action and/or are being brought back into action, they are at least once, brought into an intermediate leve. In this position the stitches formed previously are still in the proximity of the needle opening, and they have not yet slipped over the latch on to the shaft. The end needles are consequently able to take the thread from the guide in the zone into which they are pushed, without the previous old stitches being drawn down. The needles to be put out of action are raised to the intermediate level mentioned, twice, before being lowered to their position of rest. The quality of the goods is improved and productivity is increased.

Title: Leak detection for nuclear plant heat exchanger - by activation to non-active substance leaking from secondary to primary circuit
Inventor: TSU DAVID DIPL ING
IPC: G21C17/00
Filed: 1978-03-11
Abstract: A method of detecting a leak in a heat exchanger between the primary and secondary circuits of a nuclear power plant is intended esp. where the pressure in the secondary circuit is higher than that in the primary circuit. A radiologically non-active tracer substance, which becomes activated when irradiated, is introduced into the secondary cooling circuit of if there is a leak between the two circuits, this substance then enters the primary circuit, becomes activated and is detected by monitoring. Pref. the method is used for a helium-cooled reactor with helium in the secondary circuit. The tracer substance is argon 40 in the unactivated state and argon 41 after activation. Used for a helium-cooled reactor with helium at a higher pressure in the secondary circuit. No active material is introduced into the secondary circuit, since the argon is inactive in this initial state. However, the argon after activation in the primary circuit can be easily detected even from a very small gas sample, and is readily removed in the standard purification loop. Thus no argon remains to disturb future readings of the primary circuit.
