Title: Picker with insert for shuttle beating-up point - with two pins on picker body and mating recesses in insert
Inventor: HAAG WALTER DR ING
IPC: D03D49/36
Filed: 1976-08-20
Abstract: Picker comprises an insert at the shuttle beating-up point, which is connected by a round pin to the picker body. On the picker body are two pin-like projections and in the insert are mating recesses, which are opposite each other or at least mounting on different halves of the insert. Pref. the projections lie vertically one above the other, with max. possible spacing between them. The arrangement with pins on the picker body has the advantage that the insert has recesses which are easy to form even when produced by removal of material. As the two pins are spaced far apart, there is little stress on them, which increases the working life and operational reliability of the picker. Also, this new anti-rotation assembly lies in the cooler edge zone of the picker.

Title: Pipe internal surface treatment process - with hose inflated inside pipe after fluid application and surplus fluid draw off
Inventor: MOLSEN KLAUS DIPL ING
IPC: F16L55/164
Filed: 1976-12-23
Abstract: The process treats the inside of a pipe with a fluid, typically an immersion or sealing medium, by filling it with the fluid and then withdrawing the surplus as necessary. A hose is inserted in the pipe and inflated to an external diameter less than the pipe internal diameter, typically using gas or air to a pressure greater than the static pressure difference in the pipe after filling with the fluid. Alternatively, a fluid can be used, of nearly the same density as the treatment fluid. The fluid can be introduced into the pipe after insertion of the hose, and during or after inflation of the latter. Pressure inside the hose can be such as to cause it to expand for an amount equal to the estimated amount of treatment fluid used.
