Title: Method of preparing the surface of a transparent body so as to prevent or reduce the formation thereon of drops of water
IPC: C09K3/18
Filed: 1939-01-10
Abstract: 536,048. Treating glass to disperse water drops falling thereon. CURRAN, W. E. Jan. 10, 1939, No. 35252/38. [Class 20 (iii)] [Also in Group XVI] In order that the surface of glass, films, and other transparent bodies may disperse drops of water falling on it into films and without impairing the transparency, substantially the entire surface has formed in or on it irregularities. These latter are stated to be of the order of .0001 millimetre and are formed for example on windscreens or respirator eyepieces. The surface may be etched by hydrofluoric acid gas, e.g., gas from a 40 to 50 per cent. concentrated solution of hydrogen fluoride attacking the surface for two to three minutes. An aqueous solution of hydrogen flouride ammonium fluoride and sodium fluoride may be used; or a solution of hydrogen fluoride, with an inhibitor added. The etching may be achieved by sandblasting. If the sheet of glass is immersed in a bath of boric acid or sodium silicate and the solution evaported by a high temperature (500‹C. to 600‹C.), transparent particles fuse to the surface to give the desired irregularities.

Abstract: 1,101,759. Photo-electric turbidometers. CKD DUKLA, NARODNI PODNIK. Aug.18, 1965 [Oct.22, 1964], No.35401/65. Heading G1A. [Also in Division G2]  An opacimeter comprises a funnel-shaped container 12 through which a constant-head test liquid flows and a covering chamber 9 having one or more selenium cells 10 located on its inner wall and a light-source e.g. filament lamp 1 arranged so as to project a light beam normal to the liquid surface. The zero reading on the meter 11 is arranged to correspond to substantially zero opacity, by painting the internal surfaces white, and by utilizing masks 7, 8, converging lens 2 and a reflecting surface 14 to ensure that only a well-defined beam enters and leaves the liquid so that the dispersion is effectively all due to the liquids opacity. The opacimeter may be dipped into a flowing stream in which case compressed air is pumped into it through the upper opening in tube 6 so as to prevent liquid penetration into the upper compartments of the meter and the lower end 15 of the container is left open.

Title: Improvements in or relating to straight-bar knitting machines which are electricallydriven
IPC: D04B15/99
Filed: 1938-12-06
Abstract: 523,596. Knitting-machines. BLACKBURN & SONS, Ltd., G., START, H. W., and START, E. Dec. 6, 1938. No. 35480. [Class 74 (ii)] Automatic speed control mechanism for electrically driven straight - bar knitting-machines comprises three parallel slides A, B, C. Slide A is connected to the manually operated control rod F of the machine. Slide B is connected to the motor speed regulator, which may be of the induction type. Slide C is connected to slowing-down mechanism associated with the knitting-machine. Slide B carries a plate E with two pivoted hooks G, H by which the slides A, B, or, alternatively, the slides B, C can be coupled together. The hooks carry striking parts, G', H<SP>3</SP> engageable by spring tappets K<SP>1</SP>, L<SP>1</SP> on the slides A, C and are linked together at J. When one tappet K' or L' engages the part G' or -H<SP>3</SP>, the corresponding hook G or H is hooked on to a stud K or L, while the other hook is released. Assuming that the slides A, B are coupled and have been moved far enough .to the left to give the machine the maximum speed required and are left in this position, the speed can be reduced by moving the slowing-down slide C to the right until the slides B, C are coupled and the slides A, B uncoupled. The slides B, C can now be moved further to the right to reduce the speed of the machine to the required extent, leaving the slide A in its maximum speed position. When the maximum speed is again required, slides B and C move to the left, until at the completion of this movement, slides B C are uncoupled and slides A, B are coupled: The slide C is connected by a link to arms M<SP>1</SP>, M<SP>2</SP> on a rocking shaft M which is angularly adjusted by a lever N. A stop N' releases lever N at intervals as determined by studs on the controlling chain, or holds lever N out of action. A second stop N<SP>2</SP> limits the movement of lever N towards its cam, when released by stop N<SP>1</SP>. The lever N when released by stop N' will follow its cam until cheeked by stop N<SP>2</SP> and this movement will be communicated to slide B and the speed of the machine slowed down. The.inductor regulator P is fitted with rotary switch gear on the axle of which is a pinion P' engaging a toothed segment Q mounted on an arm Q<SP>1</SP> connected to slide B so that movement of slide B rotates pinion P' and adjusts regulator P.

Title: Improvements relating to processes for the purification and/or decolourisation of oils and fats
IPC: C11B3/00
Filed: 1936-12-31
Abstract: Oils, fats, and fatty acids, especially of animal or vegetable origin, are purified and decolorized by dehydrating and freeing the oil from solid impurities, then suspending in it in the absence of water and at normal temperatures, a small amount (between 0,1 and ,5 per cent) of a metal, metal oxide or salt in the form of a dry powder, and stirring the mixture until colour disappears, thereupon adding a small amount of an acid and heating to a temperature not exceeding 90 DEG  C., and adding a powdered adsorbent.  The oil is then filtered.  The purification may be effected in a vacuum.  The decolorized and filtered oil may be further treated at elevated temperatures and in vacuo with fuller's earth.  Metal, metal oxides and salts specified are, pulverized nickel, cobalt, zinc, manganese or copper, oxides of copper, cobalt, manganese or nickel, or salts of these metals, e.g. manganate, benzoate, bichromate or chlorate.  In an example, peanut, olive or palm oil is freed from solid impurities and 0,4 per cent by weight of manganese dioxide is stirred in.  When free from colour, 0,2 per cent of sulphuric acid is added, and slowly heated to 90 DEG C. with addition of 3 to 4 per cent of fuller's earth and charcoal.  The mixture is then filtered.  The oil is free from colour, albumins and mucins, and soaps formed therefrom do not develop any colour.  Petroleum oils may also be treated.
