Patent FR-2393947-A1 (FR)
Title: IC engine preheater control - has electronic coupling to energise heater when starter is operated
IPC: F02P19/02
Filed: 1977-06-07
Abstract: A starting switch connects a supply to a timing circuit which energises a Schmitt trigger. This operates a relay which energises the preheating circuit. At the end of the set time the trigger operates and the preheating stops. A further position of the starter switch energises the starter motor. In this position a supply is put on the trigger circuit through a diode so as to block the trigger action. The preheating circuit is thus energised regardless of the state of the timer.

Title: Metallurgical furnace wall plate cooler - esp. for blast furnaces used in ferrous and non-ferrous metallurgy
Inventor: BINEVSKY V N
IPC: F27D1/12
Filed: 1977-11-22
Abstract: A furnace wall cooler for a metallurgical furnace comprises a metal plate having at least two pipes formed in the plate with end portions of the pipes bent aside in the same direction. The end portions extend from the plate and are connected with end portions of pipes arranged outside the plate to form closed coolant circuits. Each of the pipes arranged outside of the plate are mounted in a chamber having in inlet and an outlet for coolant.

Title: Ferromagnetic wall surface for magnetically mounting displays - is made by mixing metallic particles with wall surfacing mix
IPC: E04C2/04
Filed: 1978-03-20
Abstract: A ferromagnetic surface is produced by mixing ferromagnetic particles with e.g. a plastic or cement mix before applying the mix to a wall or partition. The particles are between 0.01mm and 1mm in size and take up to 50% vol. of the mix. The particles are formed e.g. by atomising a molten metal normally ferromagnetic at ambient temperatures, pulverising metal shavings or by abrasion or from a metallic oxide. Such a surface allows the magnetic mounting of displays such as advertising displays without damaging the surface as occurs with normal fixing methods and provides an easily renewable surface.
