Inventor: DUCKWORTH WILLIAM P
IPC: H04L15/34
Filed: 1976-11-24
Abstract: The Morse-code converter for direction finding receivers consists of a signal processing stage fed from the LF output of a receiver (1). A control stage comprises a mark and space channel (3, 4) connected to a symbol counter (6) and bit processor (7). The processor is connected to a three-stage buffer store (8), each stage having three sections (A, B, C). The output buffer is connected to an output unit (14) which drives a display (15).

Title: TIG butt welding long corrugated stainless steel pipes - using flexible chamber to feed inert gas onto interior of joint
Inventor: SCHIMMEL PETER DIPL ING
IPC: B23K9/028
Filed: 1977-01-14
Abstract: Long stainless steel pipes, esp. corrugated pipes (a,b) are joined by TIG but welding, while the bore and possibly the outside dia. of the seam is supplied with inert gas. A strong core i s used to pull a strong, flexible, inert gas tube (c) through one pipe (a,b), tube (c) being attached to a tube (d) with several peripheral outlet holes for the gas. Several flexible disks are fitted on tube (d); and at least one disk enters each pipe (a,b) to form a chamber fed with inert gas during welding. The tubes (c, d) are then drawn out of the pipes (a,b). In the pref. appts., a Cu tube (d) is fitted with interchangeable rubber disks. Process prevents oxidn. forming e.g. temper colours, on the welded zone. Such oxidn. reduces the corrosion resistance of the welded joint to liq. or gaseous media flowing through the pipes (a,b).

Title: Dowel with tapered plug for fixing objects to walls - is expanded radially by shank of bolt engaging internal ridge
Inventor: KOENIGER RUDOLF ING GRAD
IPC: F16B13/06
Filed: 1977-01-15
Abstract: The dowel (2) has a tapered bore at one end to receive a tapered plug (3) which has an internal screw thread (90). The other end of the dowel (2) has an internal helical ridge (45) and short external ribs (6).
