Patent FR-2324972-A1 (FR)
Title: Ultrasonic soldering two aluminium tubes using lap joint - where one tube is coaxially located in the other tube
Inventor: WENDT MICHAEL ERIC
IPC: F16L13/08
Filed: 1976-09-22
Abstract: Tubes are joined together in an ultrasonic bath contg. molten solder. The end of one tube (1) is inserted in the end of a larger tube (2) with a prescribed amt. of radial play; a forming tool is then employed to produce radial projections in the bore of tube (2) which accurately centre tube (1) in tube (2), leaving gaps through which air can escape from the joint surfaces when the tubes (1,2) are immersed in the solder. At least one tube is pref. made of Al, and the solder pref. consists of 92-98% Zn and 2-8% Al. The top end of tube (1) is pref. kept above the surface of the molten bath so no solder flows into tube (1). Air can escape from the annular gap between the tubes during soldering, and an excellent joint is obtd.

Title: Vehicle headlamp monitoring circuit - has threshold switch coupled to reference circuit which with differential amplifier is connected to alarm signal generator
Inventor: LUMBROSO SYLVAIN JOSEPH
IPC: H05B37/03
Filed: 1976-10-06
Abstract: The incandescent filament lamp of a motor vehicle is monitored for its power supply failure. The lamp is connected between earth and the measuring resistor whose resistance is lower than that of the lamp filament. Two or more parallel connected lamps can be monitored by a single measuring resistor, and an alarm signal is generated when one of these lamps fails. The resistor and earth are connected by a compensation circuit whose current and voltage relationship is approximately equal to that of the lamp. The alarm signal circuit is additionally connected to the output of the compensation circuit, and has, on its input, a reference circuit and preferably a differential amplifier. A threshold value switch is connected to the reference circuit for producing preferably an optical alarm signal.

Title: Continuous operation veneer peeling machine - has blade cutting angle continuously altered to suit reduced dia. of wood
IPC: B23B1/00
Filed: 1976-11-15
Abstract: The process is for continuous variation of the cutting angle on wood veneer paring machines. A continuous movement is imposed on the carriage, with the blade and pressure bar set so that, for any given type of wood, the angle diminishes to zero or less than zero as the trunk dia. grows smaller. The movement of the carriage (5) is exclusively straight. During its course the cutting plane (c) on the front of the blade (1) remains parallel to itself and at right angels to the horizontal diametral plane (D) of the trunk (B). The blade cutting edge moves in a fixed plane (A), cutting the diametral plane at an angle (beta) with the edge initially below the diametral plane, then at the level of this (E), and finally, if necessary, rising above it.
