Title: Weaving loom - having dobby mechanism with no under-motion
IPC: D03C1/14
Filed: 1971-03-09

Title: Adjustable metal or plastics door frame - giving tight fitting for mass produced doors using lipped packing for frame sections
Inventor: BOCK GUENTER
IPC: E06B7/23
Filed: 1973-07-03
Abstract: The bottom cross beam of the door frame is 'U' shaped and fits over a height adjustable box beam through adjusting bolt, thus moving up or down inside the bottom cross beam. The box beam has a lip fitted with a packing. Equally the 2 vertical side frames are fitted with lip and packing.

Title: Sealing and cooling system for pipe repairs - avoids fire risk when handling in flammable gases or liquids
Inventor: SOMMER PAUL
IPC: F16L55/132
Filed: 1973-07-16
Abstract: The pipe sealing device consists of two discs with bevelled outer edges forming a V groove for an O ring and held together with a long bar screwed at each end. One end of the bar screws into the end disc and the other end carries a nut which pushes a disc against a spacer tube to compress the O ring against the pipe wall. Holes in the disc allow the inlet and escape of CO2 supplied from a high pressure bottle. The cooling due to the expansion of the CO2 forms an ice film inside the pipe. Non-ferrous or plastic materials are used to prevent sparks.
