Title: Preparation of artificial white of egg from whey
IPC: A23C21/00
Filed: 1951-12-07
Abstract: The filter cake, containing lactose crystals, proteins, phosphates and calcium salts, produced in the manufacture of artificial white of egg from whey (see Group VI), is used as a fodder.ALSO:Artificial white of egg is made by raising the pH of whey or concentrated whey to between 9 and 10.5 and removing, e.g. by filtration, the precipitate which forms.  The pH may be arised initially to 11-12 and then reduced to 9-10.5 adding carbon dioxide or a bicarbonate). Raising of the pH should preferably be done quickly, e.g. in 15 minutes.  The whey may be concentrated to contain at least 55 per cent solids, preferably 65 per cent, so that some lactose crystals form and may then be diluted to contain about 50 per cent solids.  At least 10 per cent of lactose crystals based on the weight of the concentrated whey may be allowed to form on cooling.  The size of these crystals should preferably be about 10 to 100 microns.  The pH may be raised by adding an alkali metal hydroxide, e.g. sodium hydroxide, or a basic salt, e.g. sodium carbonate, or an amine.  The salt content of the white of egg may be reduced at pHvalues between 6 and 8 by electrodialysis, e.g. by the method described in Specification 679,338, [Group XXXVI].  Powdered artificial white of egg may be obtained by drying the liquid white at temperatures below its coagulation point.  Saccharose or a saccharose solution may be added to the liquid white of egg and the mixture may be concentrated, e.g. in vacuo, to give a product resembling condensed milk.  Examples are given of the production of meringues and almond paste for macaroon biscuits using the artificial white of egg.

Title: A process for the preparation of barium amalgam and barium compounds
Inventor: HOLMES WILLIAM RAYMOND
IPC: C25C1/04
Filed: 1960-08-23
Abstract: Barium amalgam, produced by electrolysis of barium chloride solution using a flowing mercury cathode, is treated to prepare barium oxide or barium hydroxide.  The amalgam contains preferably 0.1 to 0.2% of barium by weight and is free of other alkaline earth metals, V, Cr, Fe, Ni, and Mo. The amalgam at about 80 DEG C. may be distilled to produce barium oxide, or treated with sufficient pre-heated water to produce a 50% solution of barium hydroxides at 80 DEG  to 90 DEG C.ALSO:Barium amalgam is prepared by flowing a stream of barium chloride solution in contact with an anode over a flowing mercury cathode, and adjusting the contact time and current density so that the amalgam contains less than 1% of barium and preferably 0.1-0.2%. The barium chloride solution is concentrated near to saturation (about 350-400 g. per litre at 50  DEG C.), and the exhaust solution still contains 325 g. per litre, the solution being maintained at about 75  DEG C.  The barium chloride solution may be formed by treating barium sulphide clinker with HCl and maintaining the pH at 7-9 by retaining excess of the sulphide, whereby detrimental metals are precipitated, e.g. other alkaline earth metals, V. Cr. Fe, Ni, and Mo.  After filtration, the sulphides are removed by HCl, and a filtrate of pH 3-5 is obtained.  The amalgam produced is freed from barium which may be converted into oxide by distilling the amalgam, or by treating with water to form barium hydroxide.  The mercury is then recycled.

Title: Improvements in or relating to systems for determining the radio-activity of gas sols
IPC: G01T7/04
Filed: 1959-08-28
Abstract: 927,225. Measuring radio-activity. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 28, 1959 [Sept. 2, 1958], No. 29449/59. Class 40 (3). In a system for determining the radio-activity of a gas sol comprising a first device for determining the intensity of alpha-radiation and a second device for determining the intensity of betaradiation and wherein the system also includes absorption means through which the radiation passes prior to detection, it is arranged that the absorption is such that the ratio between detected beta-particles and detected alpha-particles for the natural radio active series based on radon is the same as the ratio for the natural radio-active series based on thoron, whereby any departure of the measured radio-activity from this ratio indicates the presence of other than natural radio activity in the gas sol. Gas to be tested is pumped through inlet 1 and passes through a filter paper 3 to an outlet 5 leaving a deposit 8. Above the paper is an alpha-particle counter 2 comprising a photo-multiplier tube 9 facing a luminescent layer of zinc sulphidesilver crystals carried by a light conductor formed of acrylic resin, and below the paper is a beta-particle counter comprised of a Geiger counter tube 15 with a mica window 16. In carrying out the invention, one or more thin sheets 17 of paper are provided over the window 16. Beta radiation from the thoron series is more readily absorbed than that from the radon series, the thickness of the paper sheet(s) being chosen having regard to the other absorbing elements in the radiation path, i.e. mica window 16, filter paper 3 and air, that the detected beta to alpha ratio for the thoron series corresponds to that for the radon series. In operation of the apparatus, the filter paper is subjected to step-by-step movement between feed and takeup rolls 35, 36. During movement of the paper, alpha-particle counter 2, which is normally pressed into gas-tight contact with the paper by springs 13, is lifted out of contact with the paper by displacement to the right of a bar 27 which rides upwards on supports 30, 31. Provision is also made to switch off the high-voltage supply to the photo-multiplier and to stop the gas pump. To permit a measurement to be made after natural radio-activity has decayed for a number of hours, there is provided a second pair of detectors 21, 40 disposed an appropriate (and adjustable) distance along the filter paper from the first pair 2, 15. In carrying out the invention, the beta-particle counter 40 of this second pair is also provided with paper sheet(s) 42.

Filed: 1960-08-26
Abstract: 913,780. Electric tests. T.I. (GROUP SERVICES) Ltd. Sept. 13, 1961 [Aug. 26, 1960], No. 29495/60. Class 37. The cross-sectional area of a magnetic tube or rod 1 is determined by passing it through a coil 3 which saturates it magnetically and then amplifying, integrating and measuring at 6 the E.M.F. in a further coil 5 surrounding the rod. The Specification explains that the output of the coil consists of three terms, one dependent on the coil area, one on the saturating field and the other a constant. The integration is set so that with no tube present the second and third terms cancel each other so that the instrument indicates tube area directly. In a further embodiment a pair of detecting coils are provided whose areas are inversely proportional to the turns ratio and the difference is a measure of tube area. If an alternating saturating field is used the maximum values of each half-cycle are constant but of opposite polarity. These values are subtracted so that double the first and second terms referred to above and no constant appear in the output. The meter is initially set to read double the second so that the first is indicated directly.
