Title: Self-closing valve for shower head - has elastic material valve stem to exert sufficient force to close valve even under low flow conditions
Inventor: STRANGFELD REINER DIPL ING
IPC: F16K31/40
Filed: 1977-05-20
Abstract: The self-closing valve has a piston moving backwards and forwards in a cylindrical housing with a lateral water inlet. An overflow channel passes through the piston, with a pressure discharge valve, and a shaft projecting into the water outlet connections of the housing.

Title: Twist detecting device - using pair of grooved drums to monitor twist in roped fabric web and actuate a detwister
Inventor: KURODA MITURU
IPC: D06B23/08
Filed: 1978-04-27
Abstract: A twist detecting device is used in detwisting appts for roped web or woven fabric. The appts. has a pair of sensing drums each with axial grooves formed on at least part of the surface. A rod is fixed to another portion of the drum and extends laterally and perpendicular to the axis. The drums are arranged side by side in parallel between which the roped web passes parallel with the grooves. The drums are supported and as the web passes through the drums rotate and the rods swing. An actuating bar is pivotally connected to the rods and moves axially in either direction. Hence the direction of the twist is indicated by movement of the bar which is made to produce an electrical signal by the interaction of the bar with two prepositioned switches. Used for detecting the direction of the twist in a roped web after processing and then quickly and accurately sending a signal to detwisting appts. to remove the twist.

Title: Spot welding gun - with pressure compensating line joining piston actuators for each electrode
Inventor: ERMERT WILHELM
IPC: B23K11/31
Filed: 1978-08-09
Abstract: Spotwelding gun has a fluid-pressure actuator for each of the two electrodes. The pistons operating the electrodes move in the opposite direction and their approach stroke chambers are connected to a common pressure medium source to compensate the pressure exerted by them. Arrangement saves the additional weight of mechanical compensating devices to absorb any uneven surfaces on a workpiece. This extra weight is important if the gun is used by a robot. It automatically compensates irregularities in any welding position.
