Patent DE-2037869-A1 (DE)
Title: Coiler for hot wide strip - using pressure rollers and guides
IPC: B21C47/06
Filed: 1970-07-30
Abstract: Instead of using the transport bogey as part of a strip guide system, three rollers and three guide plates are positioned close to the mandrel so that the leading end of the strip is forced to form a tight coil. The rollers and guides are then withdrawn until the end of the strip approaches when the thre rollers, together with a fourth, are used to support the coil and to slow it down to a standstill. The design is such that there is room for the transport bogey with a 'V' section platform to be placed underneath the coiler during coiling, ready to receive the finally coiled bundle.

Title: Needle bar alignment - using two stepped plates operated by control pads
Inventor: LOOSE GERHARD
IPC: D04B7/28
Filed: 1973-05-18
Abstract: Designed for a flat knitting machine, one stepped plate represents full needle movements, while the steps on the other plate represent shifts at half needle intervals. The plates are adjusted when in the depressed position by a control linkage and control pads so that when they are raised, the steps move operating plungers, this movement being transmitted to alignment bars for the needle beds. This provides an alignment function from the normal movements of the operating slide, to increase pattern ranges without diminishing productivity, and without the need for complex precision components.

The cams can be mounted either on the shaft itself or, preferably, on a separate shaft linked to the main shaft by suitable cog wheels.
Patent DE-2349089-A1 (DE)
Title: Magnetic valve without sealing gland - has union thread segregated from corrosive material e.g. nuclear fuel
Inventor: LEICHSENRING CARL HANS DIPL IN
IPC: F16K27/08
Filed: 1973-09-29
Abstract: In this design the thread of the union is segregated from the main through pipe. The union that holds the valve housing itself has a chamfered edge that is pressed against a correspondingly chamfered face on the main pipe. The angles are different so that a conical shape linear seal is achieved. The entry and exit pipes for the valve have a conical end section. They are tightened into position by external unions that press them against conical spigots pointing outwardly from the valve. By virtue of the inward laying of the gaskets corrosion of the valve threads is avoided. A smooth flow through is assured by the fact that the cone gaskets can seal right to the tips.
