Title: Anticorrosive paint - for metal contains a rapid drying complex catalyst
IPC: C09D5/08
Filed: 1972-03-07
Abstract: Paint compsn. as base for multilayer anticorrosive paint on metal, contains a rapid drying catalyst under ambient temp. and humidity comprising a complex halide, e.g. a chlorostannate or chloroplatinate of multivalent metals (Fe, Zn, Sn or Sb).

Title: Electronic ignition system for automobile engine - has distributer coil signal fed to tachometric generator with integrated output
IPC: F02P5/155
Filed: 1974-01-28
Abstract: A magnetic distributor coil (2) produces a signal dependent on engine speed and engine suction which is passed through a wave shaping circuit (3) to feed a tachometric generator (4). The output of the latter is passed through an integrator (5) which gives an output voltage U proportional to the angular position of the driving shaft. This voltage is compared in a comparator (7) with a reference voltage obtained from a potential divider (6). When the two voltages coincide an output signal magnified by amplifiers (8, 9) interrupts the current through the primary of the ignition coil (10). A three position switch (15a) changes the reference voltage between starting, running and idling conditions. The switch is moved by the combined effect of the accelerator and choke positions.

The extensions are then glued, and the box folded so that the sides (2, 4) adhere to the extensions. When the sides are moved apart before use, the base is formed automatically, the narrower flap supporting the wider.

Title: Automatic smoke generator for foodstuffs - with device for spreading sawdust over electric heating plate and for removing ashes
IPC: A23B4/052
Filed: 1975-11-28
Abstract: Smoke generator, with an automatic device for the distribution of the sawdust and the removal of the ashes, is intended for use in the food industries for the smoking of meat or fish partic. of hams. The sawdust is contained in the hopper; it is pushed into a chute by rotating blades. A constant mass of sawdust, equal to the width of the perforated distribution plate, is obtd. A rake, consisting of washer fixed to the end of an arm itself articulated to the driving chain, draws the sawdust onto the plate through which it falls on the heating plate. When the rake arrives at the position it is stopped by a an electric microswitch for a sufficient time to assure complete combustion of the sawdust on the heating plate to produce smoke for the treatment e.g., of hams. The cycle then starts again. The device is simple and efficient; it distributes the sawdust on the heating plate, by gravity, in a regular manner according to a definite cycle.
