Patent GB-909960-A (GB)
Title: Processes for preparing refined silica
IPC: C01B33/18
Filed: 1960-10-31
Abstract: Pure, fine grained silica is produced by reacting impure and coarse silica, e.g. sand, with a boiling aqueous solution of fluosilicic acid to produce water, and silicon tetrafluoride which is then hydrolysed by another solution containing fluosilicic acid, which may be at 40 DEG -80 DEG C., to precipitate pure fine silica. The fluosilicic acid content of the solutions may be from 20 to 60% by weight and the solution may contain sufficient silica dissolved to saturate the solution when at the temperature of stage 2.  The residual solution from the first stage may be used as the solution in the second stage.  The impure silica stock before treatment is ground or screened preferably to pass a screen of mesh size 0,15 to 0,06 mm. The silica precipitate is separated by filtration and may be washed with water to recover fluosilicic acid which is then recycled. Alternatively, the silica may be drained and dried at 100 DEG -300 DEG C. to remove fluosilic acid as silicon tetrafluoride, which is recycled.  A batch process is described in which, after treatment of one batch of sand, the aqueous fluosilicic acid used for the hydrolysis step is used in the first stage of treatment of a second batch, and the aqueous fluosilicic acid used for the first stage is used in the hydrolysis step of the second batch.  A continuous process is also described in which aqueous fluosilicic acid is circulated between the first and second stages, with intermediate filtering.ALSO:Ultra-fine silica, which may have a specific surface area of 250 sq. m./g., is used as a reinforcing filler in smoked sheet rubber material.  It may be used in the proportion 55 parts by weight silica per 100 parts rubber, and cured at 143 DEG C. for 15 minutes.

Title: Improvements in or relating to radiation indicators
Inventor: VALE RAYMOND LESTER
IPC: G01T1/04
Filed: 1960-11-02
Abstract: 920,689. Radiation indicators. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Oct. 26, 1961 [Nov. 2, 1960; Aug. 14, 1961], Nos. 37652/60 and 29240/61. Class 98 (1). A radiation indicator comprises a film deposited from an aqueous emulsion of a halogen-containing polymer composition, the aqueous phase of the emulsion having incorporated therein an acid-sensitive dye which gives a colour change when the film is exposed to radiation. Suitable compositions are polymers and copolymers of vinyl and vinylidene chlorides, and suitable dyes are Dimethyl Yellow, Waxoline Yellow (Trade Mark), Meta Methyl Red, Congo Red, Thymol Blue and Xylene Cyanol. When the film is exposed to radiation, the hydrogen halo-acid (e.g. hydrochloric acid) is liberated, and affects the colour of the acid-sensitive dye with which it comes into contact. The said dye may be a watersoluble dye dissolved in the aqueous phase, or an oil-soluble dye emulsified in the aqueous phase. Indicators of the above type require protection against visible and ultra-violet light, to which they are sensitive. Protection against ultraviolet is afforded by the incorporation of ultraviolet absorbers such as benzophenone derivatives, either in the film itself, or in a coating, or by coating with a layer of common rosin or colophony. Protection against visible light is afforded by incorporating in the coating a dye having similar absorbtion characteristics to those of the dye in the film itself. The sensitivity of the indicator may be reduced by adding an organic water-soluble base such as triethanolamine. The indicator film may be painted, printed, or applied in any other suitable way, on to a package, label, tape, &c. Three specific examples are given.

Title: Method of and apparatus for supporting material in sheet form
IPC: C21D9/63
Filed: 1965-09-07
Abstract: A method of supporting a glass sheet on a cushion of gas comprises, admitting a combustible fluid to a plurality of chambers which are open at the top and arranged to form a blowing surface, burning at least part of the fluid within the chambers and supporting the sheet by means of the emerging gases, these latter being allowed to escape between the chambers.  Combustible gases are fed into a water cooled chest 6 from where they pass up tubes 9 (Fig. 1, not shown) emerging through restricted openings 11 and distributer grids 5 into combustion chambers 2 where the gases burn.  The burnt gases support the glass sheet 1 and exhaust down the spaces 3 between the chambers. The tubes 9 are made of material which is a poor conductor of heat and the space between them is filled. with refractory heat insulation.  In alternative forms of chamber 2 (Figs. 2 and 4, not shown) an annular space 24 is formed between the wall 4 of the chamber and a cylindrical partition 12 above the grid 5.  A diluting gas, e.g. air, is fed from nozzles 13 in the tops of the partitions 12 to mix with the combusted gases which have burnt in a lower chamber 14 bounded by the portion 12 and the grid 5, the nozzles being so positioned that the ensuing gases cause turbulence.  This enables the temperature of the supporting gases to be controlled.  In a further embodiment (Fig. 6, not shown) a support bed is made up from a series of units each comprising six combustion chambers, similar to those described in Figs. 2 and 4, connected to a common frame having a lower chest 21 from which the combustible gases are fed, and a small upper one 20 supplying the diluting gases.

Title: Improvements in or relating to lithographic printing machines
IPC: B41L19/00
Filed: 1959-11-11
Abstract: 876,838. Printing machines. RITZERFELD, W., and RITZERFELD, G. Nov. 11, 1959 [Nov. 26, 1958], No. 38182/59. Classes 100(1) and 100(2) In a lithographic offset printing machine the offset cylinder is moved into contact and away from the forme cylinder during a first rotation of the latter, the timing of these movements being determined by setting means to correspond with selected lines or text portions on the printing plate, and during a further rotation of the forme cylinder the offset cylinder and an impression cylinder co-operate to effect printing on a sheet in a closed up manner of the selected lines or text portions. As shown, the power-driven shaft 1 of the forme cylinder 2 carrying a printing master sheet 23 is coupled by gears directly to the impression cylinder 7, and indirectly through a magnetic clutch 13 to the offset cylinder 14. Associated with the cylinder 2 there is an electric contact for each line on the master sheet 23 and settable from a keyboard, and a contact arm rotates with the cylinder to engage those contacts which are set up and thus cause an electromagnet 17 to act through a linkage 18, 19 to draw the offset cylinder 14 into contact with the sheet 23. In the engaged positions of the cylinders 2, 14, gears 22, 21 thereon are in mesh. After each line is transferred to the cylinder 14 the latter is spring-urged away from the cylinder 2 so that the gear 21 is engaged by a spring-loaded rack 43 which arrests the cylinder 14. When the forme cylinder 2 has completed one rotation, a contact is operated to cause an electromagnet 45 and link 46 to draw the rack 43 away from the offset cylinder, and a further electromagnet 148 is de-energized. A spring-urged arm 50 can now urge the offset cylinder 14 against the impression cylinder 7, and the magnetic clutch 13 is, operated to cause the cylinder 14 to be power-driven to print on a copy sheet on the cylinder 7. The printing master sheet 23 is inked by apparatus 78-82, and damped by apparatus 73-77. Feeding sheets:-Sheets 24 are fed from a pile by a sucker 25 and an oscillating sucker arm 31 on each third rotation of the forme cylinder 2, the arm 31 being connected by a resilient link 57. to a rotating crank plate 16. The sheets are taken by grippers 52 on the cylinder 7, and delivered to a rotating sucker arm 10 which drops them on to a pile at 55. If a sheet is not accurately registered against a sheet holder 29, operable by an electromagnet 59, two photo-cells 32 cause suction to be cut off from the arm 31, and also start a motor 33 to drive a cam disc 36 for one revolution only, which through a link and roller 37, retracts the cylinder 7 from the offset cylinder 14. Set-off, preventing.-After each printing rotation of the cylinder 14, the electromagnets 17, 45 and magnetic clutch 13 are controlled to allow a free running of the cylinder 14 for cleaning. This cleaning is effected by a cam controlled roller supplied with a liquid from a bath.

In a recording circuit for converting a single marking on one of a plurality of leads into a combination of markings on a second plurality of leads by means of electromagnetic devices each having a plurality of windings, the windings are so polarized as to cause spurious inductively induced pulses to cancel each other out. In the simplest embodiment, Fig. 1A, a single earth marking on one of three leads 1, 2, 3 is converted into a two-out-of-three marking on three leads a, b, c, in accordance with the illustrated table, by means of three relays R 1 , R 2 , R 3 , each having two windings. When, for example. lead 1 is earthed to energize the X windings of relays R 1  and R 2 , and hence to mark leads a and b, inductive " kicks " are induced in the Y windings of relays R 1  and R 2  which pass through the windings of relay R 3 , but as these windings are oppositely polarized these " kicks " cancel each other out and there is no risk of relay R 3  picking up spuriously as there would be if its windings were not oppositely polarized. Six other embodiments using this principle are described. It is stated that transformers or magnetic amplifiers could be used in place of the relays.
