Title: Casting of ingots, esp. by electroslag remelting - where mould is rotated in alternate directions round its longitudinal axis
IPC: B22D23/10
Filed: 1974-05-16
Abstract: Ingots are mfr. from a liq. metal obtd. by melting a semi-finished metal product or a consumable electrode and filling the cavity in a cooled ingot mould which is rotated round its longitudinal axis during the growth and solidification of the ingot. The novelty is that the mould and the solidified skin it contains are rotated through an angle of 5-180 degrees with the direction alternating at 1-300 cycles per minute. The process is pref. applied in electroslag remelting. The oscillation of the mould produces a fine, dense, cast structure which improves the workability of alloys which are difficult to deform; casting speeds can be increased in electroslag remelting and the ingots can be successfully inspected ultrasonically. The oscillation of the mould breaks up the coarse dendrites and increases the number of nuclei from which solidification proceeds.

They are also effective against tarsonemes and eriophydes, but are harmless to useful insects and have low toxicity o homeothermes. They are useful in forestry and with vegetables, citrus fruits, vines and cotton.

Title: Magnetic head for reading information codes - uses double gap to sense binary interval between magnetic print bars
Inventor: DROUOT JEAN-MAX
IPC: G06K7/016
Filed: 1974-10-22
Abstract: Machine-readable documents are coded with strips of magnetic ink bars, the interval between bars corresponding to either 0 to 1. The strip is magnetically saturated and then read by the double head (11) which has gaps (14, 15) in its magnetic circuits.

IPC: C02F1/58
Filed: 1975-01-02
Abstract: Ammonia is removed from aq. effluents by stripping with air, then ammonia is removed from the sir stream by absorption in an acid soln. (pref. pH 6.5) contg. H2SO4 or HCl; the air is recycled; (NH4)2SO4 or NH4Cl are recovered. The aq. effluent is preliminarily treated with an alkali to adjust the pH to a value above (pref. >11).

The air cycle is closed, whereby CO2 is not supplemental and precipitation of CaCO3 from the alkali-treated effluents is avoided. NH4Cl and (NH4)2SO4 can be recovered and utilised (the latter as a fertiliser).

Title: Tyres with a compressed rubber lining on the sidewalls - to increase matrix modulus without higher hysteresis effects
IPC: B60C13/00
Filed: 1975-02-25
Abstract: Tyres have the sidewalls lined internally with an ancillary layer of rubber which is in compression when the tyre stands in an inflated but unloaded state. The design is esp. intended for radial ply carcass tyres. The compression stresses in the side walls generate a tension in the carcass which relieves and can even supercede internal pneumatic pressure for sustaining the inflated shape of the tyre. The sidewall stresses generate a circumferential stress in the sub-tread reinforcement which inhibits radial distension. As the tyre flexes during cornering the compressive stresses, are enhanced and self correcting for maintaining the proper carcass shape. Precompression increases the modulus of the rubber, hence its load bearing capacity, without increasing the hysteresis losses, and hence overheating, when flexing under high loads or speeds.

Title: Fused glass furnace - with transformers for separate electrode pairs, having cross-connecting controllers for low-impedance inter electrode path
IPC: H05B3/00
Filed: 1975-05-29
Abstract: Fused glass can be heated at a faster rate by the Joule effect by using several pairs of electrodes, each with its own AC supply transformer and control unit. In addition, an electrode of one gp. can be connected to an electrode of another gp. vai a current path of low impedance to that the individual transformer and control unit. In addition, amelectrode of one gp. can be connected to an electrode of another gp. via a current path of low impedance so that the individual transformers act in series on a selected portion of the fused glass mass. The glass surface thus need not be kept hot by additional sources of heat, directed on the surface. No transformers of higher tension are required and if the glass temp. rises beyond a threshold, the extra heat input is cut off.

Patent FR-2399066-A1 (FR)
IPC: D06B23/28
Filed: 1976-03-19
Abstract: The process permits the process course when dyeing or optically brightening textile material according to the exhaust method, - e.g. with respect to the quality of the dyeing or the brightening effect and/or to the minimisation of the expenditure of time, energy or auxiliary chemicals to be consumed -, to be conducted optimally. For the determination of the concentration change of the dyestuffs or optical brighteners in the dyestuff or optical brightener single- or multi-component system employed, this system is considered on the basis of the empirical values in the immediate past using a model in order to determine the optimal control parameters which are used as discrete operating or control values for the self-adjusting direct digital control of the course of the process. Using this process, the course of the process when dyeing using dyestuffs or brighteners which in solution do not obey Lambert-Beer's law can be optimally conducted.

Title: Extn. of red wine anthocyanin(s) from grapes - without destruction from oxidase(s) which are eliminated by high temp.
IPC: C12G1/028
Filed: 1976-05-28
Abstract: Predrained crushed grapes are raised from ambient to 65-75 degrees C, such that rise through the zone of 40-60 degrees C is almost instantaneous. The grapes are then steeped in wine in a closed chamber, to dissolve out the colouring matters (anthocyanins, etc.) from the grapes. In the through stage, wine still permeating the marc after fermentation and pressing is washed out with water to provide a second grade wine for distillation. A pref. first stage comprises pre-heating the grapes to below 40 degrees C and mixing them with a pressurised stream of must supplied at 90-95 degrees C. The proportion of must to grapes is such that the temp. of the mixt. settles almost instantly at 65-75 degrees C. The process is pref. carried out in screw press extractors in series, the screws having perforated, hollow shafts through which heated must (stage 1) and washing water (stage 3) are brought into contact with the marc. Oxidases on the skin of the grapes destroy colouring matteres in a few seconds at 40-60 degrees C. This is not allowed to happen as this zone is passed through too quickly and the temp. continues to rise to 65-70 degrees C which eliminates the oxidases.
