Abstract: 461,669. Automatic exchange apparatus. RANGABE, A. R. Aug. 17, 1935, No., 23148. [Class 103 (iii)] [Also in Group XXXIII] A method of towing into the air an advertising device consisting of an elongated banner sign 10, Fig. 1, consists in attaching a loop of cord 18 to one end of the device which is spread flat upon the ground, supporting a length 24 of the loop horizontally above the ground on temporary supports 20, Fig. 4, so as to extend transversely to the longitudinal direction of the advertising device, and collecting the length of cord 24 by means of a collecting device, for example a grapnel 26, suspended from an aeroplane flown across the length of cord towards the advertising device so as to strip the latter from the ground. The banner sign, of the kind comprising a number of cord or tape stringers connected transversely and secured to a spreader bar 12, is attached by shroud lines 14 to a ring or eye 6 through which is threaded the cord 18, adapted to be engaged by the grapnel 26 comprising a shank and forwardly-curved arms and secured to a cable 32 which during take-off is maintained coiled on an upwardly and rearwardly inclined arm 34 pivoted at 36 to an undercarriage or other strut. Arm 34 is held in place by a withdrawable catch 42. The banner may be caused to fly in an upright position by weighting one end of spacer bar 12.

IPC: C09D101/18
Filed: 1939-08-11
Abstract: 533,639. Lake pigments; finger nail enamels. DU PONT DE NEMOURS & CO., E. I. Aug. 11, 1939, No. 23264. Convention date, Aug. 16, 1938. [Classes 2 (ii) and 2 (iii)] A pigmented finger nail or like enamel composition is produced by bringing into direct contact with a solution of a dye particles of zinc oxide, of such small particle size as to be non settling in a cellulose derivative enamel vehicle, chemically precipitating the dye on the particles of zinc oxide to produce a lake pigment and thereafter incorporating the pigment in a cellulose derivative enamel vehicle. The diameter of the zinc oxide particles is preferably of the order of 0.12 to 0.18 microns. In examples of the preliminary production of the lake pigments, (1) an aqueous solution of the dyestuff, 2-chloro-4-aminotoluene-5-sulphonic acid - 2 : 3 : 6 - naphthol - disulphonic acid, is mixed with an aqueous suspension of the finely divided zinc oxide known under the trade name " Kadox," the mixture is brought to the boil, an aqueous solution of barium chloride is added and the whole further boiled for 10 minutes, whereupon the lake pigment is filtered off, washed free from chlorides and dried at 65‹C. ; (2) a solution in dilute acetic acid of the dyestuff, 2-chloro-4-aminotoluene-5-sulphonic acid # 2 : 3 - hydroxynaphthoic acid, is mixed with a similar suspension of zinc oxide with addition of calcium chloride, the mixture is boiled for 20 minutes and the lake pigment separated as in (1). In an example (3) of the preparation of a finger nail enamel, the lake pigment obtained as in (1) or (2) above is milled into a solution of cellulose nitrate in alcohol and dibutyl phthalate, the whole is dissolved in a mixture of ethyl acetate, butyl acetate and alcohol and the solution is mixed into a solution of cellulose nitrate in ethyl acetate, alcohol and dibutyl phthalate. The Specification as open to inspection under Sect. 91 (4) (a) comprises also an example of the use of a basic dye, viz. Basic brown G or BR, from which a lake pigment is prepared by mixing it with a suspension of the zinc oxide, heating the mixture to 60‹C., adding an aqueous solution of barium chloride and separating the product as in (1) above. The use of the pigments in cellulose ester enamels, dopes and plastics generally is also specified. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in or relating to the polymerisation of olefines
Inventor: WRIGHT BERNARD
IPC: C08F10/00
Filed: 1956-07-31
Abstract: Olefins, e.g. ethylene, are polymerized by the Zeigler low-pressure method in the presence of a liquid having the catalyst suspended and/or dissolved therein and under such conditions that the olefine or olefins are supplied to the liquid in the gaseous or vapour phase under a pressure which is varied during the polymerization so that a substantially constant rate of polymerization is maintained.  The polymerization may be effected continuously and the catalyst may be added portionwise. The temperature of the polymerizable mix may be used as a measure of the rate of polymerization.  The Zeigler low-pressure method is described.  Specifications 799,392, 799,823, 801,031 and 803,557.  In the present process the catalyst is made by reacting aluminium diethylmonochloride and titanium tetrachloride and the liquid in which it is dissolved is isooctane.

Abstract: 1,009,295. Centrifugal fans. ROTRON MANUFACTURING CO. INC. June 8, 1964 [June 20, 1963], No. 23634/64. Heading F1C. [Also in Divisions E2, F2 and H2] A centrifugal fan has a tubular outlet of circular cross-section provided with a number of keys angularly spaced around its outer periphery by means of which the fan can be mounted on a support at its outlet in any one of a number of angularly spaced positions. The fan outlet having four keys 24, Fig. 4, is mounted to a support 38 having at least two key receiving slots 40. An air hose may be connected to the outlet. The fan housing, Figs. 4, 5 and 7, which is in two parts aligned by a pin and may be of plastics material, may be secured to a support (not shown) in any one of three angular positions by self-tapping screws engaging plain holes around the axial inlet 25, or by screws engaging threaded bushes received in holes adjacent the plain holes. Additionally, these screws may connect to the inlet an L- shaped bracket carrying an air hose. The fan may be supported in any angular position by clamps bolted to a support (not shown) and engaging a peripheral slot 64 in a base 50 cemented or press-fitted over an electric motor 46. When the fan is supported in this manner the housing 21 may be replaced or removed and not used. The assembly of impeller 47, motor 46 and base 50 is fitted to the housing 21 by passing three radial tongues 52 on the base 50 through cut-outs 32 in the inner periphery of housing flange 56 and then rotating the assembly relative to the housing 21 to sandwich the flange 56 between the tongues 52 and a peripheral flange 54 on the base 50. A flat resilient member 58 is secured to the housing 21, with cut-outs 60 aligned with cut-outs 32, by clips 59 and depressed portions which engage depressions 61 in the housing wall. Three raised portions 62 on the member 58 are, on relative rotation of the housing and assembly, engaged by the tongues 52 to secure the assembly axially. The assembly may be arranged in any one of three angular positions relative to the housing, for example for improving access to the motor leads. Pads 34 extending axially from the housing 21 are of such length as to engage notches 72 in the periphery of flange 54 and secure the assembly and housing against relative rotation, but are capable of being forced manually out of the notches to allow the flange 54 to ride over them.

Pulveruient-fuel furnaces; casings and walls; regenerators.-In a furnace for the reduction of iron and other ores of the kind comprising a reduction shaft 6<1> communicating with a combustion chamber 6, the combustion chamber is fired by powdered fuel and high-temperature air and the hot gases from the combustion chamber, passing first through a heat interchanger, are drawn upwards through the reduction shaft under a sub-atmospheric pressure. The combustion chamber walls are strengthened by inclined water-cooled tubes 28 (which constitute a boiler supplying power for the furnace machinery) and the furnace comprises also special constructions of heat interchanger, and fuel dust supply means. The fuel is delivered by a conveyer 3, Fig. 11, to a shoot 4 containing guides 4<1> arranged fanwise, Fig. 9, which distributes it along a delivery brush 5, Fig. 1. The resulting jet of fuel is met by highly heated air from the nozzle 20 at a slight inclination to it and the flame produced, giving mainly carbon monoxide, is directed slightly downwardly 'against the wall 9 of partially reduced ore which is thereby melted into the well 2. The heat interchanger through which the gases now pass comprises parallel air aud gas passages, the gas passages being lined with refractory cement such as Arcorundum retained in place by steel members of U-section formed with staggered snags 34, Fig. 7. An auxiliary independently fired air heater may be employed in addition when poor fuel is used. The partially cooled gases after passing through a dust trap are admitted by flues 13 and inlets 26 to the base of the reduction shaft.
