Abstract: 939,153. Continuous metal-heating furnaces; skid rails. HUTTENWERK OBERHAUSEN A.G. April 17, 1962 [May 23, 1961], No. 14720/62. Class 51 (2). A pusher type furnace for ingots, blooms or slabs comprises a succession of heating zones starting with a preheating zone and ending with a heating zone adjacent to which is the furnace discharge point, each zone having lower and upper combustion chambers below and above water-cooled slide rails that extend through the zones to the discharge point, the rails being provided with metal saddles from which uncooled ribs project upwardly to provide the carrying surfaces for the material to be heated. In the form shown, the furnace has two successive zones, a preheating zone I and a single heating zone II. Slide rails 2 run through the zones from the inlet to the discharge point 7. In each zone combustion chambers 3, 4 are respectively located above and below the rails, the material 1 on the rails being top and bottom heated throughout its travel. The slide rails 2 consist of rectangular, water-cooled tubes 13 carrying, with an interposed air gap, saddles 5 each having a central longitudinal rib 6 the upper surface of which forms the carrying surface for the material. The saddles may have side insulation 5a and the rails 2 may be supported where they pass over the lower combustion chambers 4 by water-cooled transverse tubes as described in Specification 859,901. The rails, which in a modification may be set at an angle across the furnace, are arranged so that they may be withdrawn and replaced without shutting-down the furnace. In operation the formation of " black streaks " is avoided since the ribs 6 attain the same temperature as the furnace gases.

Title: Improvements in dishwashing apparatus
IPC: C02F1/461
Filed: 1956-05-11
Abstract: 831,687. Purifying and importing special properties to water. GENERAL ELECTRIC CO. May 11, 1956 [May 12, 1955], No. 14730/56. Class 46. [Also in Groups XXIII and XXXVI] Relates to a water demineralizing unit in a dishwashing apparatus (see Group XXIII). The water demineralising unit 30, Fig. 4, comprises a stainless steel outer tubular casing 31 constituting a cathode earthed at 96 and a carbon or graphite rod 32 constituting an anode connected at 95 to the positive conductor of a D.C. electric supply and supported axially within the casing 31 by means of insulating discs 63, 64. An insulating sleeve 74 surrounds the rod 32, the lower end of the sleeve, within the casing 31, being perforated as at 76. The inner forces of the discs 63, 64 are provided with annular grooves 68, 69 and gaskets 70, 71, to receive and support the ends of a porous ceramic tubular barrier 33, coaxial with the rod 32 and casing 31, the discs being held in a liquid-tight manner in the casing 31 through the agency of a flange 61, gaskets 65, 67 and a clamping ring 66 operable by screws 72 and nuts 73. The annular space between the perforations in the sleeve 74 and barrier 33 constitutes an anolyte chamber 36 whilst the annular space between the barrier 33 and the casing 31 constitutes a catholyte chamber 35. Spaced from the discs 63, 64 by rings 80, 83, within the chamber 36 are perforated discs or screws 78, 79 and the space between the latter is filled with a heterogeneous mixture 34 of about 50% porous cation exchange material and about 50% porous anion exchange material. The cation material is formed from a strong acid resin e.g. phenol-aldehyde resins whilst the anion material is formed from a strong basic resin e.g. urea-formaldehyde resins. Water can be passed downwardly through the resin exchange bed 34, the water entering, at 41, a small orifice 98 in a resilient flow control plug 97 into a tubular member 86 fitted in the disc 64 and thence through passages 88 in the disc into a chamber 84 above the screen 79. On passing through the bed 34 the water enters a chamber 81 below the screen 78 and then passes through passages 87 in the disc 63 to a tubular outlet 40 fitted in the disc 63. Water can be passed from an inlet 37 upwardly through the catholyte chamber 35 to an outlet 38. The arrangement of the unit 30 is such that water is passed continuously through the catholyte chamber 35 at the slow rate of about 45 litres per month whilst water is supplied intermittently to the anolyte chamber 36, e.g. once a day for a short period at the rate of about 11 litres per minute, an electric potential of 7 volts D.C. being continuously applied across the anode 32 and cathode 31. Water passing through the unit 30 is thus treated by ion exchange and electrodialysis to convert hard water into soft aqueous acid rinse solution to eliminate deposits of mineral salts on the dishes which latter when washed and dried have unusual brilliance and sparkle.

Title: Process for extraction of certain vitamins from materials containing the same, and of increasing the potency of the extracted vitamins
IPC: A61K31/525
Filed: 1930-05-20
Abstract: Water-soluble vitamins, particularly vitamins B and G, are obtained by subjecting suitable parent materials such as rice polishings, wheat embryo, or yeast to an extracting action, and treating the extract with a glacial acetic acid and acetone to produce a concentrate by precipitating admixed impurities.  In an example, rice polishings are treated for 48 hours with agitation with aqueous ethyl alcohol acidulated with acetic acid.  The residue is treated with the same solvent for 24 hours, and the combined extracts after filtration are distilled under reduced pressure.  The viscous residue is dissolved in glacial acetic acid, anhydrous acetone is added, and the granular precipitate which forms is separated and washed with acetone.  The washings and solution are combined, and the acetone and most of the acetic acid successively distilled off at reduced pressure.  The acetic acid remaining in the viscous residue may be neutralized with alkali, but preferably distilled water is added, and the resulting liquid spread in a thin film is allowed to evaporate under ordinary conditions, with the aid of a current of air if desired. Alternatively, the residue remaining after distilling off the acetone and most of the acetic acid is diluted with water, and the vitamin content thereof selectively adsorbed with suitable adsorbents such as active carbon or silica gel, after adjusting the hydrogen ion concentration of the liquid with the aid of acids, alkalis, or buffer salts to a predetermined optimum value. When the starting material is rice polishings and active carbon is used as the adsorbent, a pH value of 4-5 is suitable.  The vitamins are subsequently set free from the active carbon by washing twice with decinormal hydrochloric acid, followed by two extractions with aqueous ethyl alcohol.  The acid washings and alcohol extract are distilled under reduced pressure, leaving the vitamin concentrate as a gummy residue.  Prior to setting free the vitamins from the active carbon, the latter may be washed with 90-95 per cent ethyl alcohol, the washings added to the liquid residue of the adsorbtion treatment, and any unadsorbed vitamin suitably recovered from the combined liquids.
