Title: Method for end point determination in the production of thixotropic polyamide-modified vehicles
IPC: C09D167/08
Filed: 1958-08-27
Abstract: Vehicle bases suitable for formulation with predetermined vehicle solvents for the production of thixotropic coating compositions are made by reacting with heat a polyamide resin derived from polymeric fatty acids and alkylene polyamines, and, if required another substance such as an aliphatic dicarboxylic acid with a vehicle base until a test solution of the reaction product in said vehicle solvent, wherein said test solution contains said reaction product in an amount at least 25% by weight, is clear at room temperature. Various graphical methods are disclosed of determining the end point such that any colour produced during the reaction and any initial cloudiness are allowed for.  Specified initial vehicle bases are the reaction products of monohydric or polyhydric alcohols with polybasic acids, which reaction products may be oil modified, the reaction products of fatty acids with polyhydric alcohols, alkyds and the reaction products of oils with oil soluble resins, e.g. phenolic resins, maleic resins, epoxy resins and polymerised hydrocarbons. Specified vehicle solvents are mineral spirits, aromatic hydrocarbons, paraffins and low boiling naphthas.  Specified solvents in which the reactants and products are soluble, used in the graphical methods are esters, alcohols and ketones.  Specified vehicle bases are made by reacting the polyamides with alkyds made by reacting (a) soya bean oil or linseed oil, refined or distilled tall oil, maleic anhydride, phthalic anhydride and pentaerythritol in the presence of lime hydrate or litharge; (b) refined soya or linseed oil, pentaerythritol and phthalic anhydride in the presence of lime hydrate and (c) dehydrated castor oil fatty acids, dehydrated castor oil, phthalic anhydride, benzoic acid, pentaerythriol and ethylene glycol.  Exemplified vehicle solvents are mineral spirits and xylol. U.S.A. Specification 2,663,649 is referred to.
Patent GB-1072172-A (GB)
Title: Composite catalysts
IPC: B01J23/89
Filed: 1965-06-11
Abstract: Carbon monoxide is methanated and hydrocarbons steam reformed in the presence of a catalyst comprising 0.1 to 2% Pt and 8 to 50% Ni and/or Co, the remainder being an aluminous and/or MgO support. In an example a light naphtha is steam reformed at 770 DEG  C. and a pressure of 20 kg/cm.2 and a steam/carbon ratio of 3.5 to yield a gaseous mixture of CO2-16.2%; Co-9.8%; H2-67.0% and CH4-7.0%.  This gas was dried and fed to a methanation reactor maintained at 440 DEG C. which reduced the Co content to 0.5% and the H2 content to 9.3% and increased the CH4 content to 70.4%.  The catalysts in the steam reforming zone and methanation zone contained different proportions of Pt and Ni.ALSO:Hydrogenation catalysts contain 0.1 to 2% of Pt and 8-50% of Ni anc/or Co, the remainder being an aluminous and/or magnesia support.  Additionally the support may include Si)2, or a hydraulic binder, e.g. lime water or an aluminous cement.  In an example the catalyst is soaked in KOH solution.

Title: Improvement in and relating to the manufacture and manipulation of colloidal or semi-colloidal substances, precipitates or sediments and the separation and recovery of the liquid or solid components
IPC: C22B34/12
Filed: 1924-10-20
Abstract: Solutions containing oxides or salts of titanium, thorium, and rare earths are clarified by adding a small quantity of a gelatinous substance such as glue, gelatin, albumen or casein. The colloidal suspended matter in a solution obtained by the treatment of ilmenite or monazite with sulphuric acid may be separated in this manner.  In the case of ilmenite, the iron is reduced for instance by iron borings as described in Specification 1835/03 before or after the clarification, the ferrous sulphate being then removed by crystallization.  The separated colloidal matter may be dried to form a red-brown pigment.  The titanium sulphate solution is boiled and poured into boiling water to precipitate titanium oxide.  The gelatinous substance that was added for the clarification assists the precipitation, and a further small quantity may be added for this purpose.  Reference has been directed by the Comptroller to Specification 228,814.

Abstract: 1497569 Automatic control of tension CONTINENTAL OIL Co 11 June 1975 [4 Nov 1974] 25070/75 Heading G3R Tension in a pipe-line is kept constant by automatically controlling the position of a "turn vehicle" 30, round which a 180 degrees loop is formed, in response to an electrical signal indicative of the pipe-line tension exceeding prescribed limits. The limits may be selected according to whether the end of the line is advancing, stationary, or withdrawing. The "vehicle" may be self powered but as shown it is moved by a winch 64 and the tension is measured by a transducer responsive to the pressure in an hydraulic piston and cylinder 68 connected in the winch cable. Similar transducers may be positioned at bends as at 60 to give an alarm and immobilize the control if tension bÞcomes excessive. The complete system comprises an hydraulic slurry transport pipe 26 and its supply 27, with pneumatic and electrical control lines 48, used in a mine with a work face 18.

Abstract: 388,098. Kinematograph apparatus. VICTOR, A. F., 242, West 55th Street, New York, U.S.A. Sept. 8, 1931, No. 25229. [Class 97 (i):] A speed-controlling mechanism of the type in which a rotatable member is actuated in conjunction with film feeding means and limited in its centrifugal movement by a brake adapted to control the speed of rotation of the rotatable member is characterized in that the rotatable member is a shoe pivotally supported on a rotatable carrier, the brake normally engaging the shoe to arrest the movement thereof and being movable to selective positions to vary the speed of the shoe. As shown in Fig. 1, the clockwork-actuated gear 12 drives pinion 13 which is integral with the cam-shaped hub 14 of a gear 15 rotatable on spindle 16, secured to which parts are the shutter 17 and the cam that reciprocates the claw plate 20. The claw 22, Fig. 11, is one arm of an inverted U- shaped wire the transverse portion of which is rockably mounted on the slide so that the other arm is urged by spring 24 to press claw 22 towards the film. A pinion 28 meshing with gear 15 is mounted on a sleeve 29 rotatable on a stud 30, Fig. 4, and having a flange 31 pivotally mounted on which are shoes 32 forming a conical surface secured to which by pins 38 are friction members 37. Stops 39, Fig. 6, limit centrifugal movement of the shoes by engagement with openings 40. The engagement of springs 41 with studs 42 constitutes a positive return. Coacting with the outer conical surfaces of the shoes is a brake ring 43 of interior frusto-conical shape and having ears 44 the lower engaging a guide 45, and the upper provided with a tubular extension 46 slidably mounted on a guide 47, which is surrounded by spring 48 engaging a stop-pin 49. A cam 50 on a spindle 51 carries a roller 53 engaging the upper ear 44 of brake ring 43. A plunger 55 extending through a bushing 57 and surrounded by a spring 59 engages a pin 54 on cam 50. The plunger 55 carries a radially. projecting pin 61 adapted to enter slots 62 .. 65, Fig. 9, for locking, normal speed, ultra-speed and half-speed respectively. The slot 63 is L-shaped to permit the plunger 55 to be turned to hold the mechanism at the normal speed position. The gate plate is provided with a stamped-out spur to prevent backward movement of the film.
