Title: Aluminium alloy mfr. using prealloyed briquettes - contg. flux which evolves gas, ensuring uniform distribution of alloys in melt
Inventor: GUERIT PIERRE
IPC: C22B21/06
Filed: 1975-05-28
Abstract: Pellets or briquettes contg. a pre-alloy or metal and employed in the prodn. of aluminium alloys contain in addn. to the finely divided metal or pre-alloy, a flux which evolves gas when placed in the molten bath of metal. The wt. ratio of metal to flux is pref. between 1:1 and 20:1, and the pref. flux is eiher (a) a halo-hydrocarbon which is solid at room temp. esp. hexachloroethane; or (b) a salt mixt. of alkali (ne earth) metal(s) and/or aluminium, at least one salt evolving gas in the molten bath. Simplifies the addn. and dissolution of alloying elements such as Mn, Cu, Fe, Si, Ni, Zn, Co, Cr, Bi, Cd, Zr, Be or B in molten aluminium to obtain the correct compsn. prior to casting despite differences in density and/or slow dissolution speeds. The rapid and uniform distribution of the allowing element(s) throughout the bath, obviates the slow and arduous hand stirring previously necessary.

Title: Matrix printer with e.g. wire printing head - distance between wires and line of print equal to at least line pitch
IPC: B41J2/505
Filed: 1975-07-23
Abstract: The printing wires are so positioned on their carrier that the spacing of the wires in the line direction amounts to at least two column pitches. More specifically the spacing of the wires at right angles to the printed lines corresponds to a two line pitch while the spacing in the line direction corresponds to a three column pitch. The printing mechanism can be controlled to vary the size of the printed symbols. By spacing the printing wires in the way indicated allows 'micro-lines' in different lines to be printed e.g. the micro-lines MZI to MZ9. Ink jet printing heads can be employed in place of the wire printing heads.

Title: Flour temp. adjuster for bread-making dough - whilst spread in thin layer in a closed circuit, heated or cooled air flow
IPC: A21D6/00
Filed: 1977-03-30
Abstract: Kneading process and plant for bread-making dough comprises a tank in which the flour is treated, before mixing with water, so that its temp. is such that the bakehouse temp. plus the water temp. plus the temp. of the flour is 56 degrees C. The flour is subjected to the action of the closed circuit air current inside a tank to control its temp. The plant consists of a fixed tank inside an insulated chest the flour is poured into the hopper and is carried by the endless screw to the foot of a vertical screw. This raises the flour to the top of the tank where it is poured over the conical surface where it meets a downward current of air, from the fan, which has passed over exchange surfaces to heat or cool it as required. The blades ensure that the flour is distributed in a thin layer so that thermal exchanges are effected rapidly between the air and the flour. The treated flour falls back into the tank while the used air passes along the channel and is drawn up the vertical return channel to complete the closed circuit. A well-oxygenated flour is obtd. which improves the quality of the bread produced from the flour. The process ensures that the flour temp. is equal to that of the water.
