Title: Improvements in or relating to the clarification of fermented beverages
Inventor: WALLES WILHELM EGBERT
IPC: C12H1/052
Filed: 1963-02-13
Abstract: Fermented beverages are clarified by adding a minor proportion, preferably from 0.0007-1.4% by weight based on the weight of the beverage, of animal blood albumin which has not previously been irreversibly coagulated, and subsequently removing the precipitate formed. The clarification is carried out at a temperature within the range of from the freezing point of the beverage up to 80  DEG C. Beverages mentioned are beer, ale, porter, grape and other fruit or berry wines, champagne, sake, brandy, whisky, gin, vodka, tequila and cider.  The animal blood albumin may be added in the form of natural blood plasma, as water-soluble dried blood, or as an aqueous solution or dispersion of the dried blood.  According to an example, to 100 ml. of a commercially available bottled beer having an alcohol content of about 3.5%, there was added at room temperature 1 ml. of bovine blood plasma that had not been irreversibly coagulated containing 7.1% blood albumin, 91.3% water and 1.6% fats, sugars and salts.  In less than an hour a fine, distinct precipitate had settled out at the bottom of the beer. The treated beer was then filtered rapidly through ordinary filter paper to yield a clear beer.

Abstract: 253,174. Copeman, L. G. March 6, 1925. Casting refrigerators.-Comprises moulds for the inner and outer cement shells of the domestic refrigerator described in Specification 253,175, which may be separate structures or combined in one. The mould for the inner shell comprises a base a, Fig. 1, a dowelled outer wall e<2> with de tachable cover f, and readily removable box cores c, d, e centred in the base bv dowels. A dovetailed wood strip 20. Fig. 6, placed at the bottom of the space between the cores and mould, is - cast in the material and forms an insulated contact between the shells at the front when they are assembled one inside the other. The core j, Fig. 2, to form the opening in the horizontal partition is a dovetailed wedge-shaped member driven into a corresponding socket formed on the face of the core e. It is provided with a groove k to form a rib around the opening. Internally-threaded bushings p, with their ends flattened to prevent turning, are held in suitable positions in the mould by means of screws o, and are cast in the shells to receive screws for fastening the shells together. The cement material is poured into the mould through a tube g, Fig. 6, and after setting the mould is turned over on to the cover j, when the base a, cores c, d, e, and wall e<2> are removed, allowing the core j to be withdrawn by a lateral movement. The mould for the outer shell, Figs. 9 and 13, comprises a base and wall member open at the top, and a core q having stiffening-ribs t. The core and base are provided with complementary grooves r, s of a shape to form stepped door frames in the casting, and a perforated metal strip reinforcement u may be held in the grooves by removable bushings v and screws w. The side of the mould is provided with a laterally removable core z to form leg parts for castors. The cement is first poured into the grooves r, s through a tube y and then the bulk is poured into the open top of the mould until the material rises in the tube y, which may be closed. The mould for the inner shell may be inserted or embodied in the core q of the outer mould so that the two shells may be cast together. An inner cast-in core of wood, such as California red wood, may be embodied in the walls of the shells, to lessen the weight of the structure.

Title: Improvements in apparatus for the exploration of the ground by alternating currents
IPC: G01V3/06
Filed: 1927-03-04
Abstract: 267,501. Ambronn, R. March 11, 1926, [Convention date]. Prospecting for minerals; magnetic tests. -In prospecting for ores by passing an alternating current through the ground by direct or inductive connection and plotting the equipotential curves or the magnetic lines of force caused thereby, the effect of dephased components of the earth current is corrected for by passing an auxiliary current of the same frequency through the testing circuit. In the arrangement shown in Fig. 1, a non-inductive resistance W1 is inserted in the lead L conveying alternating current to conductors in the ground. Across an adjustable portion of this resistance are connected variable non-inductive resistances W2, W3, which are connected to a variable part of a resistance W4 in the circuit of a pair of testing-probes S1, S2 and an amplifier v to which is connected a telephone T, or a rectifier R and galvanometer G, or both. The probe S2 is arranged at a normal distance from the probe S1, and the resistances W2, W3, W4 are adjusted until a minimum sound is produced in the telephone T or a minimum deflection is obtained on the galvanometer G. The probe S2 is then moved until a zero indication is obtained, an equipotential line S1, S2 being thereby determined. In a modification, Fig. 3, the compensating current from the lead L to the testing- circuit is transmitted through transformers U1, U2, between which is a -phase displacer PhS. The compensating current may alternatively be derived from probes in the ground or by induction from a coil on the surface of the ground. The testing-circuit may contain a search coil instead of the probes S1, S2, the magnetic lines of force due to the current passing through the ground being determined in this case.

Title: Improvements in or relating to briquetting
IPC: C10L5/16
Filed: 1953-03-06
Abstract: In a process for briquetting particulate moist or moistened material such as fuels, ores and fuel/ore mixtures the base material is mixed with a binding agent and the resulting mixture shaped, the binding agent being a hot tar pitch melt comprising (1) a coal tar pitch/"solubiized" coal mixture, or a coal tar pitch made by blowing with oxygen or an oxygen containing gas but in the absence of both steam and air together and (2) an aromatic compound constituted by two or three rings in an amount up to 40 per cent, by weight of the pitch tar melt.  Suitable aromatic compounds are crude naphthalene, anthracene or phenanthrene.  The binding agent may also contain a fluxing agent such as anthracene oil or pitch redistillate.  The material to be briquetted may if dry be treated with a wetting agent such as gas condensate or it may be mixed with sulphite waste liquor, the sulphite waste liquor being mixed with the material either before or simultaneously with the tar pitch melt.  In a modification the coal tar or coal tar pitch used for the production of the tar pitch melt may be partly or wholly replaced by other pitches which contain aromatic hydrocarbons, for example wash oil pitch or brown coal tar pitch. The materials which may be briquetted include dry ores and moist ores, e.g. iron ore, a mixture of chalk and iron ore, blast furnace dust, ore dust, blast furnace dust sludge, or flotation sludge, alone or in admixture with fuels, e.g. coke slack sludge, coke slack, coal sludge, coal or anthracite dust.  The briquettes may be calcined and/or sintered when containing e.g. materials which are hydroxides or oxides of alkaline earth metals such as magnesium hydroxide or oxide, calcium hydroxide, sludge resulting from the production of acetylene from calcium carbide, or chalk. In an example a fine grain magnesium hydroxide containing 40 per cent of water is mixed with 7 per cent of a tar pitch melt consisting of 25 per cent of anthracene and 75 per cent of hard pitch blown with air is shaped and dried at 80 DEG C.  The dried pieces are calcined and sintered in a kiln while raising the temperature up to about 1600 DEG C. Specifications 237,959 and 239,474 [both in Class 50] are referred to.
