Title: Improvements in or relating to the pasteurisation of beverages in bottles
IPC: A23L3/02
Filed: 1960-07-14
Abstract: 897,770. Pasteurizing foods in sealed containers. BARRY - WEHMILLER MACHINERY CO. July 14,. 1960 [July 23, 1959], No. 24525/60. Class 49. [Also in Group XIII] In the pasteurizing of products such as alcoholic or non-alcoholic foods packaged in closed containers, involving the steps of raising the product temperature in a first zone followed by product cooling in a subsequent zone, a refrigerating medium is circulated between the zones to provide in the first zone heat of condensation which is transferred to the product to induce the rise in product temperature. Bottles of products P, conveyed on a load-carrying grate or walking-beam platform 73 of the character described in Specification 690,181 (see Group XXX), are pre-heated by warm water sprays issuing from a header 84, are pasteurized by hot water sprays from the header 91 and the pasteurized products are cooled by sprays of water from headers 97 and 101; the sprayed water is continuously recirculated in the respective zones by pumps 86, 92, 98 and 103. The refrigerating system includes a compressor 85, condenser coils 88, a receiver 107, a high-temperature evaporator 100 and a low-temperature evaporator 104. Undue variations in the temperature of the pre-heating water in the reservoir 74, normally maintained constant by the condensation of the refrigerating medium in the coils 88, may be remedied, for example at the commencement and termination of operations by the provision of a temperaturecontrolled steam-heating coil 81 and a supply of cooling water through a temperature-controlled valve 89; an overflow 90 prevents excess filling of the reservoir. The water in reservoir 75 for effecting pasteurization is heated by steam supplied to a coil 94 through a temperatureactuated valve 96. The temperature of the cooling water in the reservoir 77 is kept constant by the controlled evaporation in the evaporator 104 of refrigerating medium snifted through a thermostatic expansion-valve 109; a control switch 120 causes the compressor 85 to be stopped or unloaded when excessive suction pressures arise from the closure of valve 109. Pre-cooling by water from the reservoir 76 may be similarly effected by evaporating refrigerating medium in the evaporator 100 under the control of a water temperature-actuated expansion valve 113; a further valve 116, solenoidoperated in response to the water temperature, is incorporated to allow the two evaporators to operate at different temperatures from the same compressor, condenser coils and receiver. It is stated that when products in metal containers are being processed, this pre-cooling may be omitted. Figs. 4, 5 and 6 (not shown), depict conventional systems of pasteurizing apparatus.

Abstract: 1,212,124. Recovering metal salts. MALLINCKRODT CHEMICAL WORKS. 23 May, 1968, No. 24770/68. Heading C1A. [Also in Division B1] An aqueous solution of a non-volatile metal compound is obtained from a solution of the compound in an organic solvent by submitting the organic solution to steam distillation until all the organic solvent has evaporated and the required aqueous solution of the metal compound remains in the distillation vessel. In an example, a solution of fluotantalic acid in methyl isobutyl ketone (obtained by solvent extraction of an aqueous solution resulting from the cracking of columbium/tantalum ore) is submitted to steam distillation in a polyethylene bottle provided with a polyethylene sparge tube. On a larger scale, the process may be carried out in a packed distillation column. An organic solution of fluocolumbic acid may be treated in the same way. The process may be used for the purification of uranyl nitrate, and to recover hafnium thiocyanate from an organic extract separated from an aqueous feed containing hafnium and zirconium compounds. The separation of cobalt and nickel by solvent extraction with a solution of tri-isooctylamine in xylene or kerosene, followed by steam-distillation of the extract of the cobalt-amine complex, is referred to.

Title: Manufacture of sulphamic acids of 2-aminoanthrahydroquinone-disulphuric acid esters
IPC: C07C307/10
Filed: 1931-09-04
Abstract: Sulphamic acids of 2-aminoanthrahydroquinone disulphuric acid esters are prepared by subjecting a 2-aminoanthraquinone or a derivative thereof containing a free b -amino group or groups to reduction and to treatment, in presence of a tertiary base, with sulphur trioxide or an esterifying agent which yields sulphur trioxide whereby sulphuric acid residues are introduced in one operation both into the enol-groups and the free b -amino group or groups of the anthrahydroquinone residue.  Reduction of the aminoanthraquinone can be effected for example by alkaline vatting, catalytic hydrogenation, or by the use of a metal, and the crude solution of the sulphamic acid compound can be used directly for diazotization, the products being useful as intermediates for azo dyes.  In examples, (1) 2-aminoanthraquinone is treated in pyridine with chlorsulphonic acid and copper powder at about 40 DEG  C.; analysis indicates a sulphamic acid of 2-aminoanthrahydroquinone disulphuric acid ester: (2) 2-aminoanthraquinone is treated with hydrogen in pyridine and in presence of a nickel catalyst and the resulting solution introduced into the addition product of pyridine and chlorsulphonic acid: (3) 2-aminoanthraquinone is vatted by means of alkaline hydrosulphite, the leuco compound precipitated by addition of sulphuric acid and heated with dimethylaniline to remove water; the suspension is then introduced into a chlorbenzene suspension of the addition product of dimethylaniline and chlorsulphonic acid: (4) 2,6-diaminoanthraquinone is treated as in (1).  The treatment of 1-chlor-2-aminoanthraquinone and 2-amino-3-bromanthraquinone is also mentioned.  Specifications 186,057, 202,630, 202,632, 261,139, 312,243, [all in Class 2 (iii), Dyes &c.], and 372,562 are referred to.  The Specification as open to inspection under Sect. 91 (3) (a) relates to the above treatment applied to aminoanthraquinones generally, and to the manufacture of azo compounds by diazotizing the resulting sulphamic acid, coupling with an azo component and, if required, eliminating the sulphuric acid residue from the product.  It is stated that diazotization by means of nitrite and acid yields the diazo compounds of aminoanthrahydroquinone disulphuric acid esters which couple to form easily soluble azo compounds from which sulphuric acid residues can be split off by acid oxidation.  Such azo compounds can also be obtained from aminoanthrahydroquinone disulphuric acid esters, the latter being obtainable by saponification of the corresponding acylamino derivatives.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1,064,664. Aerials. SPERRY RAND CORPORATION. June 17, 1964 [June 17, 1963], No. 25023/64. Heading H4A. In a microwave aerial system comprising a paraboloidal reflector and a focally-located feed horn, the concave surface of the reflector is made optically reflective and is provided with a bonded layer of optically transparent beads so that any unwanted energy picked up in the optical wavelength range is scattered and neither causes the reflector to heat up nor is concentrated on the feed horn, whilst energy in the microwave range is focused normally. As described, a layer of optically reflective material 17, such as glossy white enamel, is first applied to the reflector surface 15. A bonding coat 19, which may be a clear urethane resin of refractive index about 1À5, is next applied to a thickness of from 0À002-0À003 inches. Then a single layer of lead glass beads 21 of refractive index 1À91, whose diameter is chosen as suitable for the working frequency, and may be from 0À007-0À011 inches for the 4000-8000 Mc/s. band, is dry-sprayed on and, finally, a protective coating 23 of a translucent synthetic rubber of refractive index 1À52 is applied. If the surface of the reflector is naturally lustrous the reflective coating 17 may be omitted. The beads may be made of other materials of higher refractive indexes than glass, such as quartz or synthetic resin, and may be pre-treated with cellulose acetate butyrate, vinyl butyrate resin &c. before application to the reflector. The finishing coating 23 may be omitted if environmental conditions are not severe. The reflector may form part of a Cassegrain type aerial and in this, and other complex aerial systems, the surfaces of secondary reflecting elements may also be coated with similar light scattering layers.
