Title: Improvements in or relating to coating metals
Inventor: SAMUEL ROBERT LIONEL
IPC: C23C6/00
Filed: 1954-03-09
Abstract: 776,865. Casting composite articles. DIFFUSION ALLOYS, Ltd. Feb. 28, 1955 [March 9, 1954], No. 6857/54. Class 83 (1). 'Metals are coated with another metal or alloy by casting in a mould which has been provided with a coating of a powder containing or consisting of the coating-metal or alloy, and a fluxing medium. The coating metal, e.g. chromium aluminium, zirconium, nickel, cobalt, copper, alloys thereof and silicon, is preferably applied to the mould in powder form by spraying, dipping or painting, and is preferably suspended in a liquid, e.g. water, alcohol, or an organic composition such as a varnish. A flux may be added, such as salts of the coating metal or other metals such as halides, or organic silicates or borates. The coating may be localized to selected places on the casting, which may be iron, steel, aluminium, zinc and alloys thereof, whilst molybdenum, tungsten, titanium, and alloys thereof may be vacuum-cast. In an example, a sand-mould was sprayed with a suspension of 100 parts, 300 mesh, ferrochrome powder, 2 parts. of sodium chloride and 25 parts of ethyl silicate dissolved in alcohol, and a steel bar was cast in the mould and provided with a coating of chromium. A number of other specific examples are quoted. The mould may be a resin-bonded shell-mould.

Title: Improvements relating to telephone systems
IPC: H04M3/523
Filed: 1933-03-07
Abstract: 411,461. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and HUMPHRIES, H. E., 61, Rochester Way, Blackheath, both in London. March 7, 1933, No. 6885. Drawings to Specification. [Class 40 (iv).] In a system in which an allotting switch is associated with a plurality of groups of callfinders allotting an idle one in any required group as the occasion arises and in which each group comprises ungraded finders (each individual to a group selector) followed by graded finders (sharing a group selector), the arrangement is such that if at the end of a call there is still a calling signal in the same subgroup of calling lines, the allotter is only able to allot a new finder by a direct-hunting operation over the remainder of the group if the previously-used finder was an ungraded one. If it was a graded one the allotter is driven right round its bank to the beginning of the group in order that the ungraded finders may be tested first. The invention is described with reference to a system substantially identical with that described in Specification 400,733, but with the following additions : (1), each sub-group starting-wire contains jack contacts at which a statistical meter in series with a removable wire-link may be inserted, and (2), in the case of graded finders a permanent-glow lamp indicates which of the finders sharing a group selector is in use when a permanent loop occurs. Specifications 381,995, 408,439, and 411,463 also are referred to.

Patent GB-796817-A (GB)
Title: Improvements in or relating to the preparation of 2-keto-úý-gulonic acid
IPC: C12P7/60
Filed: 1955-03-16
Abstract: 2-Keto-l-gulonic acid is prepared by subjecting l-idonic acid or a non-toxic l-idonate to the oxidizing system produced by cultivating a colourless strain of Micrococcus aurantiacus, e.g. ATCC 11731, under aerobic conditions on an otherwise sterile nutrient medium.  The micro-organism may be grown under aerobic conditions on an otherwise sterile neutrient medium containing l-idonic acid or an l-idonate. Alternatively, l-idonic acid or an l-idonate may be added to such a medium in which growth has been established for a period not in excess of about one day.  The l-idonic acid or l-idonate may also be subjected under aerobic conditions to a fresh suspension of cells so grown, or to a cell-free both in which the micro-organism has been grown, or to an extract of the cells so grown.  The micro-organism may readily be grown on standard neutrient media, an example being a liquid medium containing a source of carbohydrate such as dextrose, inorganic salts such as potassium phosphate and magnesium sulphate, a protein source such as peptone, growth promoting substances such as yeast, and l-idonic acid or a non-toxic l-idonate.  The term non-toxic l-idonate includes salts of metals, ammonia and amines which will not interfere with the metabolism of the micro-organism, and esters of simple alcohols.  If the micro-organism, once established, is transferred daily to a fresh culture medium, or if 18-24 hour old cultures are refrigerated, the micro-organism will propagate itself in the colourless form and successfully carry out the process.  If allowed to remain in the same medium for periods in excess of one day, however, the micro-organism tends to reproduce itself in a yellow form not conducive to effecting the preparation. One method of operation comprises charging a liquid nutrient medium with sodium-i-idonate in an amount up to 30 per cent, inoculating the medium with 1 to 20 per cent by volume of a liquid, l-idonate-containing broth in which the micro-organism has been growing for 24 hours, and shaking the mixture under aerobic conditions at 25 DEG  to 40 DEG  C. for 5 to 1 days depending upon the amount of inoculum as above.  In an example, an aqueous nutrient medium containing dextrose, sodium l-idonate, monopotassium phosphate, magnesium sulphate, peptone, yeast extract and sodium hydroxide to give a pH of 7.2, is inoculated with a colourless strain of Micrococcus aurantiacus; the micro-organism is transferred daily to a similar medium from which dextrose is omitted and 10 c.c. of such a medium is inoculated into 100 ml. of a similar medium containing sodium l-idonate and the mixture is maintained at 28 DEG C. under aerobic conditions with shaking for 3 days and then 2-keto-l-gulonic acid is isolated.
