Title: Process for producing food protein from green leafy vegetably material
IPC: A23K1/14
Filed: 1972-05-23
Abstract: 1377438 Animal feed G O KOHLER and E M BICKOFF 23 May 1972 [28 May 1971] 24135/72 Heading A2B [Also in Division C3] A process for fractionating juice derived from alfalfa or other green, leafy vegetable material (specified) involves heating the juice (denoted by L-1 on the Fig.) and then cooling it to form an agglomerate containing chloro plastic proteins, chlorophyll, carotenoids and lipids while retaining cytoplasmic proteins in solution, removing the agglomerate (fraction B) from the residual juice and separating from the resulting clear juice (L-2) a protein-containing fraction (fraction C) substantially free from chlorophyll, carotenoids and lipids. According to preferred features, the vegetable material is disintegrated while in contact with an alkaline aqueous medium to which sulphite, ascorbic acid or ethoxyquin may have been added. The green juice L-1 obtained by pressing is brought to pH 5-6 (if adjustment is necessary) and then heated either at 50C for 1-5 minutes or at 60-70C for not more than 20 seconds to agglomerate the chloroplastic fraction. This is heat-treated to 80C for 1 minute, after separation, and then dried. It is stated to be particularly useful in animal feeding because it is low in fibre and high in protein, carotene and xanthophyll. Fraction A (as depicted on the Fig.) is also useful for animal feeding. The cytoplasmic fraction, stated to be particularly desirable for human use, is then precipitated out of the clear juice L-2 by acidifying it to pH 3-4.8 and/or by heating to a temperature of 55-80C. Successive treatments at lower pH and higher temperatures may be made.

Abstract: 1464863 Image converter tubes AGFAGEVAERT 8 May 1974 [21 May 1973] 24167/73 Heading H1D An electron discharge image in an evacuated envelop-produced, for example, by the incidence of an X-ray, ultra-violet, visible, or infrared image, corresponding to scanned information, on a photocathode 50-is recorded as an electrostatic charge image by accelerating it through a channel electron multiplier 51 on to the inner surface of a conductive pin matrix 56 forming part of the envelope, to be transferred thereby to the outer side of the envelope, which at the exterior ends of the pins contacts, or is in close proximity to, an insulating surface of a receiving material which is moved in synchronism with the information scanning. The channel multiplier is mounted by members 60 in close proximity to the lead or uranium photocathode 50, to obviate the need for focusing elements, and may have its channels tilted at an angle of up to 10 degrees with respect to the normal to the photocathode surface, to increase multiplication. The photocathode may contact a fluorescent screen (63, Fig. 4, not shown), sensitive to an incident X-ray, gamma ray, beta ray, or neutron image. A modified arrangement (Fig. 2, not shown), for document reproduction employs a strip photocathode 36, a multiplier having a single row of channels 35, and a single row of pins 33, the charge pattern being produced line-wise by progressive line-wise exposure of the photocathode with visible light. A variety of known methods for effecting the development of the electrostatic charge pattern are referred to.

Abstract: 1451106 Recovery of chromium from slags UDDEHOLMS AB 23 May 1974 [25 May 1973] 25050/73 Heading C7D Oxidized chromium in the slag from the refining of a Cr-containing melt may be recovered by separating the slag from the refined melt and reducing the Cr oxides with silicon, into the next charge of Crcontaining material. The preferred process involves the steps of (a) refining by blowing a Cr-containing melt in a converter (b) removing the metal (c) adding a fresh charge, containing sufficient silicon to reduce the Cr oxides, to the slag remaining in the converter (d) removing the depleted slag after reaction, (e) refine the new charge by blowing and forming a new slag (f) removing the metal, leaving a Cr-oxide rich slag which is treated as in (c). A modification which separately removes both slag and metal after blowing as in (a) above, is described wherein the slag is treated with a part of the new charge which contains the bulk of the Si required for reduction, the depleted slag being removed prior to returning the metal to the converter where the remainder of the charge is added and the whole melt refined. The process requires slags with a minimum of 10 wt. per cent of Cr oxide, and since other elements present in the oxide form i.e. Ni, Mn, Mo etc, will be reduced back by the silicon addition, the process is suitable for making alloy steels as well as stainless steels containing chromium. The silicon content required is calculated, and in the case of Cr should preferably be at least one-half the Cr content of the slag, with more if other oxides are to be reduced, extra silicon being added as ferrosilicon if necessary.
