Filed: 1948-06-30
Abstract: 653,103. Moulding by dipping. ABREY, M. June 30, 1948, No. 17613. [Class 87 (ii)] Formers are supported during their immersion by a tray comprising a series of channelsection elements A supported on a frame A<SP>1</SP> (Fig. 5), each element having therein a series of apertures of a contour shown in Fig. 1, the apertures B, B<SP>1</SP> forming an anchorage position for a former support. Each such support comprises a base-plate C carrying screws C<SP>1</SP> engaging holes in a plate C<SP>2</SP> lying in a slot in the former so that on tightening the screws the upper end of the former (which is shown in broken lines in Fig. 4), is clamped to the underface of the base-plate C at C<SP>3</SP>. Base-plate C has distancepiece D and retaining plate E secured to it by rivets F which also secure to plate E a leaf-spring G, the ends of which bear on balls H freely disposed in holes in the retaining-plate E. Parts H<SP>1</SP> pressed out of the trays A constitute stops which limit the rotational movement of the supports and at the end of the rotation the balls H are pressed slightly upwards to form a frictional lock. In a modification (not illustrated), the base C, C<SP>1</SP>, C<SP>2</SP> is replaced by a body to which the assembly D, E, G is secured by screws.

Abstract: 476,922. Facsimile printing telegraphs. STANDARD TELEPHONES & CABLES, Ltd. June 25, 1937, No. 17722. Convention date, June 29, 1936. [Classes 40 (iii) and 40 (v)] The printing hammer 9, Fig. 1, of a facsimile printing telegraph is actuated by a piezo-electric crystal 1, which is preferably composed of laminations so that the assembly bends under the action of picture signals applied at 3, 4, and so actuates a lever 7 carrying the hammer 9. The crystal assembly 1 is supported at three corners by elastic plates 2, e.g. rubber. The crystal 20, Fig. 2, is preferably connected in one diagonal of a bridge comprising valves 24, 25. Valve 24 is biassed to have a high resistance so that the bridge is unbalanced. A received impulse is applied through the diodes 26, 27 in such a way that the bias on valve 24 is rendered negative so that the bridge is unbalanced in the reverse direction and the potential applied to the crystal is thus reversed for each signal.

Title: Improvements in or relating to the production of titanium dioxide
IPC: C22B34/12
Filed: 1962-05-09
Abstract: Titanium dioxide is obtained by treating an iron- and titanium-containing material with concentrated sulphuric acid, hydrolysing, separating the dioxide from the mother liquor and concentrating the latter to at least 60% H2SO4, separating precipitated salts and dissolving them at elevated temperature in a sulphuric acid-titanium sulphate solution having a H2SO4 concentration not exceeding 30% by wt., cooling and separating precipitated iron sulphate heptahydrate from solution, recycling at least a part of said solution to dissolve more of said salts and/or hydrolysing at least part of the solution to form titanium dioxide. The whole of the solution remaining after separation of the heptahydrate may be recycled until its titanium content is from 50 to 200 g./l. expressed as TiO2. The ratio of Fe : TiO2 in the solution remaining after separation of the heptahydrate may be from 0.25 : 1 to 1 : 1, and the ratio of H2SO4: TiO2 in the salts precipitated from the mother liquor should be less than 4 : 1.  A temperature above room temperature and not higher than the boiling point of the sulphuric acid-titanium sulphate solution, preferably between 50 DEG and 80 DEG  C., is used to dissolve the salts in the acid titanium sulphate solution.

Patent GB-629468-A (GB)
Title: Improved process of manufacturing iodinated proteins and cattle-food containing the same
IPC: A23K1/175
Filed: 1946-01-14
Abstract: Iodinated protein is produced by treating protein with iodine in an acid aqueous medium, preferably at a pH of not less than 4.5, in the presence of an oxidising agent capable of liberating iodine from the hydriodic acid formed in the reaction.  Specified oxidising agents are hydrogen peroxide, potassium iodate, potassium bromate and ozone. The iodinated protein obtained may be added to cattle meal which is then added to cattle food, thus increasing the production of milk when fed to milch cattle.  In an example, casein is dissolved in water to which sodium bicarbonate is added and the mixture stirred at 40 DEG  C.  Pulverised iodine is then added at intervals and the mass stirred at 40 DEG  C.  When the uncombined iodine has disappeared a solution of hydrogen peroxide is added at intervals.  When the solution is cool, the iodinated casein is precipitated by the addition of dilute acid, e.g. hydrochloric, sulphuric or acetic acid, and the precipitate separated, washed with weakly acidified water and dried.  The iodinated protein obtained may be added to cattle meal (15 gram to 1 kg. of cattle meal) which is then added to the amount of cattle food intended for 24 hours.  The Specification as open to inspection under Sect. 91 includes an additional example in which the iodinated casein obtained as above is pressed after filtration from the mixture until it contains about 30 per cent dry material and is then mixed with compound feed.  This subject-matter does not appear in the Specification as accepted.ALSO:Iodinated protein produced by treating protein with iodine in an acid aqueous medium, preferably at a pH of not less than 4.5 in the presence of an oxidizing agent capable of liberating iodine from the hydriodic acid formed in the reaction (see Group IVb) is added to cattle-meal which may then be mixed with cattle-food for feeding to milch cattle so as to increase the production of milk.

Abstract: 438,533. Television. WILSON, J. C., and BAIRD TELEVISION, Ltd., 58, Victoria Street, Westminster. June 18, 1934, No. 17994. [Class 40 (iii)] According to one aspect of the invention, two objects 1, 7, Fig. 1, are scanned by separate beams, and masks are interposed as indicated, the signals generated in the cells 8, 9 being mixed for transmission so that at the receiver, the area 7 is inset to the area 1 on the viewing screen. According to another aspect of the invention, a " ghost " image is produced by scanning a translucent film 13, Fig. 2, and the object 12 with the same beam, so that at the receiver the view recorded on the film is seen through the object 12. Alternatively, a semitransparent mirror 25, Fig. 3, may be used to deflect the scanning beam to scan a desired portion of the object 24 which will appear as a " ghost " at the receiver. By making the mirror 25 opaque, any portion of the object 24 may be inset to the object 23. According to a further aspect of the invention, an object coloured, e.g. blue and yellow, is scanned by white light co-operating with blue and yellow sensitive cells whose outputs are mixed in a fading device, so that the blue or yelllow portions may be made to disappear by fading out the blue or yellow cell output, Fig. 4 (not shown). The effect known in cinematography as " a rolling out " may be produced by using two transmitters of the "focal plane" type as disclosed in Specification 358,916 and arranging two shutters to reveal one object and occult the other in unison. Specification 323,818, [Class 40 (iii)], also is referred to.
