Title: Manufacture of agents for wetting, dispersing or emulsifying
IPC: C07C303/06
Filed: 1930-09-10
Abstract: Soluble condensation products which may be used as solvents for extracting oils and fats and also as emulsifying agents, are obtained by treating a solution in sulphuric acid or oleum of a chlorinated polynuclear aromatic hydrocarbon, prepared under conditions whereby sulphonation is avoided, with 10 per cent or less of formaldehyde, the reaction being effected at a temperature p  below that at which the chlorinated polynuclear hydrocarbon is ordinarily sulphonated. Preferably, naphthalene or its alkyl derivatives are employed as the polynuclear hydrocarbon and instead of formaldehyde, compounds yielding the same way be used. In examples: (1) a -chlor-naphthalene or a chlorinated anthracene prepared by treating anthracene with chlorine in a solvent until 100 per cent has been absorbed, is dissolved in hot sulphuric acid and treated with a 30 per cent formaldehyde solution: (2) a -chlornaphthalene is dissolved in hot sulphuric acid after being mixed with ethyl or butyl alcohol, and is then condensed with formaldehyde; (3) a mixture of a - and b -chlormethylnaphthalenes together with some dichlormethylnaphthalenes prepared by chlorinating commercial methylnaphthalene is similarly dissolved in sulphuric acid and condensed with formaldehyde solution.ALSO:Soluble condensation products which are wetting, dispersing and emulsifying agents, are obtained by treating a solution in sulphuric acid or oleum of a chlorinated polynuclear aromatic hydrocarbon, prepared under conditions whereby sulphonation is avoided, with 10 per cent or less of formaldehyde, the reaction being effected at a temperature below that at which the chlorinated polynuclear hydrocarbon is ordinarily sulphonated. The reaction is facilitated by adding active carbon which acts as a catalyst. Preferably, naphthalene or its alkyl derivatives are employed as the polynuclear hydrocarbon and instead of formaldehyde, compounds yielding the same may be used.  The products readily wet powders and oily or greasy surfaces and may thus be used in the textile industry, e.g. in dyeing, spinning, bowking, washing and bleaching.  They also exterminate bacteria, fungi and insects and may be used as solvents for extracting oils and fats.  In examples: (1) a -chlornaphthalene or a chlorinated anthracene prepared by treating anthracene with chlorine in a solvent until 100 per cent has been absorbed, is dissolved in hot sulphuric acid and treated with a 30 per cent formaldehyde solution; (2) a -chlornaphthalene is dissolved in hot sulphuric acid after being mixed with ethyl or butyl alcohol, and is then condensed with formaldehyde; (3) a mixture of a -and-b -chlormethylnaphthalenes together with some dichlormethylnaphthalenes prepared by chlorinating commercial methylnaphthalene is similarly dissolved in sulphuric acid and condensed with formaldehyde solution.

Abstract: 455,254. Wadding. VOSS, J. A., 201, Denver Theatre Building, Denver, Colorado, U.S.A. Oct. 4, 1935, Nos. 27409 and 27410. Convention dates, Oct. 5, 1934 and May 3, 1935. [Class 142 (iv)] [See also Group VI] Fibrous material, such as cotton, is compressed into selfsustaining wads, such as the catamenial devices, described in Specification 394,571, [Group VI], in a machine comprising a compression chamber having side dies moving laterally into it, and. an end plunger entering the chamber longitudinally to compress the material and expel it into a receiving chamber longitudinally aligned with the compression chamber. The cotton is tucked by a blade 12 into the compression chamber 14 which is covered by a glass plate 15 beneath which reciprocate the side dies 16 having semi-cylindrical faces. The compressed core is expelled by the plunger 17 through a guide block 18 into one of a number of chambers 19 in a wheel 20. The plunger passes sufficiently into the chamber 19 to give a secondary compression to the cotton core so as to force it against a head-forming die 21 mounted in a reciprocating die block 69, thus producing a mushroom-like head upon the wad. Each wad is held in the wheel until it has rotated about of a revolution and the wad is then expelled by a plunger 22 into a receiver. A spring 35, adjusted by a screw 36, determines the pressure exerted on the wad by the plunger 17 which is screw-threaded into a block 32 tied to a slide block 30 which is operated by a cam-actuated lever 27. The side dies 16 are operated from cams 44 on a shaft 39 and the ejection plunger 22 is actuated through the lever 49 and link 51, Fig. 4, from a further cam 40 on the same shaft. A blade 58, which reciprocates in the space between the block 18 and the wheel 20, is provided to withdraw the strings 57 from the compression chamber. The wheel 20 is rotated by a sliding pawl 65, Fig. 6, a spring-pressed ball 84, Fig. 14, engaging recesses 83 to ensure alignment of the chambers 19 with the plunger 17.

Title: Improvements in or relating to electric discharge tubes
IPC: C09K11/02
Filed: 1937-10-09
Abstract: 503,616. Luminescent material; coating surfaces. LAISE, C. A. Oct. 9, 1937, No. 24780. [Class 39 (i)] [Also in Group III] The envelope of an electric discharge tube is provided with a coating of particles of luminescent material bonded to the surface by a material including an alkaline silicate and the coating is then treated with an ammonium salt, preferably ammonium chloride. The luminescent material may comprise sharp edged particles and is preferably sufficiently fine to pass through a 200 mesh sieve. The material may be applied by coating the interior of the envelope with the bonding medium and applying the material thereto or by applying an emulsion of particles and bonding medium to the envelope, the latter being subsequently heated. The emulsion may be applied by spraying or centrifugal action. In examples: (1) infusorial or diatomaceous earth is mixed with zinc oxide and a manganese salt, as activator, ground, heated to 1000- 1250‹ C., crushed, and sieved. The envelope, which may be clear or frosted internally, is coated internally with a solution of an alkaline silicate to which alkaline borates or tungstates may be added and the powdered material sprayed or blown thereon. The tubes are then allowed to dry and baked; (2) material prepared as above is mixed with the liquid bonding material and sprayed on the tube ; and (3) the emulsion' as prepared above is applied to the tube by centrifugal action. In all cases the coating is treated after baking with a hot concentrated solution of ammonium chloride. The tubes may be used for gas discharges, e.g. by using a filling of helium, neon, or argon and mercury. In place of manganese salts, the salts of cerium, vanadium or uranium may be used as activators.

Title: Improvements in or relating to stereoscopic telemeters
IPC: G01C3/14
Filed: 1934-09-25
Abstract: 428,759. Range - finders. GRANAT, E., 10, Rue Caumartin, and COMPAGNIE DES FORGES ET ACIERIES DE LA MARINE ET D'HOMECOURT, 12, Rue de la Rochefoucauld, both in Paris. Sept. 25, 1934, No. 27496. Convention date, Dec. 28, 1933. [Class 97 (i)] A stereoscopic range-finder is adapted for estimating the speed and direction of travel of an observed object such as an aeroplane, by providing a scale mounted so as to be adjustable in direction, an image of this scale being formed in each eyepiece and means being provided for obtaining coincidence as regards distance and orientation of the stereoscopic image of the scale with that of the object. The rate of displacement of the object along the scale, in conjunction with the ascertained range of the object enables the speed of the object to be ascertained. The scale 13 is mounted in a cardan support 17 in a casing 10 extending from the range-finder casing 1 and is illuminated from the rear by a lamp 14. Rays from the scale, after traversing a lens 19 are received by rhomboidal reflecting prisms 21, 22 and then pass through adjustable deviating devices 25, 26 to transparent reflectors 23, 24 on the axes of the range-finder objectives 7. The reflectors direct the rays to the eye-piece prism systems 8. The deviating devices 25, 26 are coupled together to give equal deviations in opposite directions and are operated by a graduated head 27. With this arrangement, operation of the head 27 causes variation in the apparent distance of the image of the scale 13 without any transverse movement of the image in the field of view. This distance is adjusted so as to be equal to that of the observed object, and the range is then read off on the head 27. Additional measuring-marks 11 may be provided in the eyepieces 12. The cardan suspension 17 is adjusted by a handle 18 to orient the scale so that its direction coincides with the direction of travel of the observed object. One of the deviating-devices 25, 26 may be omitted, in which case adjustment of the single deviating device causes the scale image to move across the field in addition to altering its apparent distance.
