Title: Brazing metal application process and applic - ator
IPC: B23K3/03
Filed: 1969-02-11
Abstract: Brazing metal piece is applied to the parts to be assembled and is maintained in position on the electrode of an applicator; it is fixed in this position by welding by means of a high intensity electric charge of short duration. The charge passes through the piece of brazing metal from the electrode to a counter electrode in contact with the parts to be assembled. The brazing metal piece is maintained on the electrode by mechanical clamping means or by suction; the electrode is integral with a handle and holds the metal and allows it to be placed in position. When the brazing metal is welded against the joint between the parts to be welded the latter are through to a high temperature in a brazing furnace; the brazing metal melts and flows through the joint, assuring a solid fixation of the two parts.

Title: Video recording system - compares consecutive frames for information changes and only records when threshold is exceeded
Inventor: BIED-CHARRETON PHILIPPE
IPC: H04N7/088
Filed: 1974-12-17
Abstract: This recording system uses the facility of a video disc recorder to repeat or hold one frame. If two similar films are compared on two telecine machines, a tape can be recorded that identifies when there has been no significant change of information between frames. This tape (32) can subsequently be used to control a video disc recorder (35) so that as the film is replayed by one telecine (31), the recording head only responds when there has been significant change between frames. The sound is continuously recorded by using a system of delays (36) and switching of sub-carriers. This method of recording ensures that only useful information is recorded thus, at least, economising on recording medium.
