Abstract: 1,066,598. Transverse-flow fans. K. ZENKNER. May 1, 1964 [May 2, 1963], No.18279/64. Heading F1C. In a transverse-flow fan in which the position of the vortex is stabilized by a tongue 27, Fig. 5, separating the inlet from the outlet, the angle # subtended by the sides 6, 13 of the tongue lies within the range 20‹-60‹, and the angle α between the diameter 26 tangential to the leading end 10 of a flow guide wall 5 and the diameter 11 of symmetry of the flow when the flow is not throttled lies within the range 20‹-40‹. The diameter 11 also passes through the point 29 at which the angle # is subtended and through the point 25 of inflexion at which the outwardly flared leading end 10 joins the main part of the wall 5. The outwardly flared inlet ends (16), Fig. 6 (not shown), of the two side walls (17) of the fan casing are aligned with the side plates (18) of the rotor to prevent flow separation.

Title: Improvements in or relating to the production of sound-record cinematograph films in natural colours
IPC: G03C7/06
Filed: 1930-06-14
Abstract: 356,817. Combined sound record and coloured picture films. BAKER, T. T., The Hut, Hatch End, Middlesex, and SPICERS, Ltd., 19, New Bridge Street, London. June 14, 1930, No. 18306. [Class 40 (ii).] In a method such as described in Specification 322,432, [Class 98 (ii), Photographic processes &c.], for the production of kinematograph films in natural colours wherein the film is first dved in one colour, then a series of lines or a pattern in resist material is applied, and the film bleached to remove the dye from the unprotected parts prior to dyeing in another colour and subsequent removal of the resist material resulting in a dye-reseau on the film, provision is made so that a sound track free from the reseau is left on the film by arranging that the resist is applied only to the picture portion. The lines of resist material, such as greasy ink, may be printed by rollers which are circumferentially recessed opposite to the sound tracks on the film which may be wide enough to cut up longitudinally into several standard width films. As an example the film may be first dyed green, then printed with lines of resist over the picture parts only, after which it is bleached and then passed through a bath of red dye prior to removal of the resist. The picture part of the film which is now covered with alternate green and red lines is again printed in a resist with lines transverse to the previous lines by another recessed roller registering with the first one, and the film is then bleached, passed through a bath of violet dye and the resist removed, leaving a reseau of green, red, and violet elements on the picture portion and the sound track dyed violet, which colour does not interfere with the recording and reproduction of sound. The film is next coated with a panchromatic emulsion and cut up or slit to the desired width. Specification 335,899, [Class 40 (ii), Phonographs &c.], also is referred to.

Title: Phototypography
IPC: B41B17/30
Filed: 1955-06-27
Abstract: 800,235. Photographic type-composing. RONDTHALER, E. and HORMAN, H. June 27, 1955 [July 21, 1954], No. 18558/55. Class98(1) A matrix for photographic type composing comprises a base sheet bearing opaque and transparent areas defining at least one series of alphabetic characters, wherein each character has a pair of convergent indicia between it and the edge of the sheet, which serves, during composition, to define the inter-character spacing. As shown in Fig. 1, the characters 14 are arranged in two lines equally spaced from the margins 18 of the matrix, which carry pairs of sloping lines 24, 26, each pair of lines corresponding with one of the characters. One line contains the most frequently occurring characters, the other, the least frequently occurring characters. The matrix is used with a movable indexing member, Fig. 2, which consists of a magnetic metallic member 31 to which a transparent member 32 is secured. Member 32 carries three sighting apertures 36, 37, 38. In use, the indexing member is placed on a steel base, on which the photographic material is also placed. The stencil is slid along the part 31 of the indexing member to bring a selected character into the exposure position, with the leading sloping line 24 corresponding to the character registering with one of the sighting apertures. After exposure of the selected character, the indexing member is slid along the edge of the matrix until the sighting member registers with the following sloping line 26 corresponding to the character. The matrix is kept stationary during this movement. A further character is then brought into exposure position, with its leading sloping line 24 in, register with the sighting aperture. The spacing between the letters is governed by the position of the sloping lines 24, 26 and may be varied by a choice of the sighting aperture 36, 37 or 38. Where a number of matrices are used for characters of different sizes, the vertical height of the index lines 24, 26 is maintained the same for all matrices, so that the spacing of the letters is proportionately increased as character size decreases. The slope of the spacing lines may be varied in order to provide variable spacing between the curved or straight parts of certain characters. The arrangement of the characters in the two rows of the matrix is alphabetical, and if the alphabet has to be divided between two or more matrices, the arrangement in each part remains alphabetical.

Title: Process for the demineralisation of bones
IPC: C09H1/02
Filed: 1930-06-20
Abstract: A process for the demineralization of bones is characterized in that the acid employed is regenerated by introducing the liquor from the demineralization vats into a determined quantity of sulphuric acid until the whole of the acid is precipitated as calcium sulphate.  The demineralizing acid used is such as will give a soluble calcium salt, as phosphoric acid.  In carrying out the process, bones are treated in wooden vats in counter-current to the regenerated acid.  Dicalcium phosphate is precipitated from the liquor by lime; in the case where phosphoric acid is employed, one-third of the liquor is so treated, but with an acid other than phosphoric acid, the whole of the liquor is acted upon. The filtrate is then added to 53-60 DEG  B<\>ae sulphuric acid in a vat fitted with a stirring device until there is a slight excess of monocalcium phosphate or other soluble calcium salt as denoted by methyl orange and phenol phthalein, or until the addition of sulphuric acid to a sample of the liquid gives an immediate baze. The liquor is then stirred for an hour to agglomerate the precipitated calcium sulphate, and after being filtered through coke, granular bone black and porous slabs, is returned to the demineralizing vats.  By thus precipitating the gypsum and filtering, it is stated that the bones do not become logged therewith, as is otherwise the case.
