Title: Metal screw cap - spring loaded insert inside hollow upper portion
IPC: F16J13/12
Filed: 1973-07-18
Abstract: Screw cap for containers or as pipe connection fitment, particularly made of metal, comprising two cover parts, movable relative to each other on their circumference, and between these a coupling bridge part under pressure spring force in a perpendicular axis direction to the cover, is inserted by means of a bearing location in groove guides of the lower threaded cover part, to form a connection with the upper rotary cap part with the aid of inclined surfaces and friction force transmission.

Title: Tungsten inert gas welding machine - with auxiliary current source for arc striking parallel to triac controlled main source
Inventor: ENSIKAT ERICH
IPC: B23K9/10
Filed: 1973-08-09
Abstract: A d.c. arc welding machine for inert-gas welding method using a non-consumable tungsten electrode (TIG-process) has an auxiliary current source to supply the additional arc striking energy at the start, and a main current source. The latter supplies the power required for quasistationary operation by absorbing from a transformer just the current to be fed into the arc. This current is adjusted by a triac on the primary side of the welding transformer or by antiparallel thyristors. This machine has a lower power rating for the same energy supplied to the welding arc than conventional machines. The reactive power load on the mains is lower and no additional power factor compensation by capacitors is required.
