Title: A device for combining a plurality of fluid streams, particularly streams of spinning compositions in a spinning apparatus
IPC: B01F5/04
Filed: 1963-06-24
Abstract: 986,246. Mixing fluids in conduits. MONSANTO CO. June 24, 1963 [June 25, 1962], No. 24994/63. Heading BIC. [Also in Division B5] In a device for mixing liquids, a first liquid from a source 14 flows through pipe 13 and chamber 12 in housing 11, passing through the grooves 20, Fig. 3, between the flanges 19 of the insert 18. A second liquid from a source 24 flows through pipe 25 to a circular manifold 28 mounted in the housing 11 and encircling the cylindrical central portion of the insert 18. The manifold has a plurality of orifices 29, each of which is aligned with one of the grooves 20 in the insert 18. Hence the liquids join, but owing to their high viscosities and low rates of flow, the flow of the combined streams is laminar and they do not mix. In Fig. 4, area 30 is liquid from source 14 and area 31 is liquid from source 24. A liquid (e.g. a spinning composition) entering at 13 may be coloured by injection of a pigment through the manifold 28, the coloured streams then being fed to a mixer which disperses the pigment in the liquid. As a number of small streams of pigment, rather than one large stream, are injected into the spinning composition, dispersion in the subsequent mixing operation is enhanced. For the application of the invention to the coloration of spinning solutions and the manufacture of conjugate filaments, see Division B5.

Abstract: 644,756. Load-handling trucks. COVENTRY CLIMAX ENGINES, Ltd. Sept. 24, 1948, No. 25032. [Class 78 (iii)] [Also in Group XXXI] In a load-handling truck the load is counterbalanced by a solid block 16 which is rotatable about a central longitudinal axis of the truck and carries a pair of road-wheels. Projecting from the rear of the truck is a boom 17 on which the block is pivotally mounted by means of a bore 161 therethrough, and along which said block is free to slide, to vary its counterbalancing moment, after a locking member (not shown) has been released. Excess rocking of the block is prevented by stabilizing springs 34 connected between the chassis and the block, but in a modification damping is effected by inserting rubber bushes 50, Fig. 3, between the block and boom, said bushes each comprising a rubber bush 44 bonded to metal bushes 42, 43 secured to the boom and bore 16<1> respectively. Bores 19 in the block form bearings for wheelsupporting shafts 21 which are coupled by a connecting-rod 26 and cranks 25, and are rotated to steer the truck by a hydraulic motor 27. In a modification (not shown), the hydraulic steering is replaced by a linkage mechanism.

Title: Improvements in the manufacture and production of metallic masses from pulverulent initial materials
IPC: B22F3/10
Filed: 1930-08-22
Abstract: In the manufacture of porous or non-poroussintered metallic masses by heating with or without pressing but without melting, pulverulent initial materials which contain impurities or are liable to take up impurities during the working up, additions are made to the initial materials of small amounts, not exceeding 1 per cent by weight, of such metals, including silicon, or compounds thereof, as are capable of forming slags with the impurities, are not volatilized and do not form volatile compounds with the impurities during sintering.  Excess of the impurities that are not slagged by up to 1 per cent of added material are removed by a purification treatment previous to or simultaneous with the sintering, for example by treatment with a reducing gas while heating, or if carbon and oxygen are present together by their interaction of during heating.  Oxygen is readily removed by the addition of known deoxidizing agents such as manganese, aluminium, silicon, vanadium, or compounds such as clay, lime, fluorspar, &c.  Sulphur and phosphorus are readily rendered non-injurious.  In the examples described, iron powder obtained by the decomposition of iron carbonyl is treated with an alloy containing 3 parts of aluminium to 1 of iron, manganese carbonate or aluminium nitrate, and a powder comprising 33 parts of cement copper and 67 parts of nickel is treated with manganese carbonate at 1000 DEG  C.  Specification 8702/15, [Class 82 (i), Metals, Extracting &c.], is referred to.

Title: Improvements relating to the opening of folded or composite paper sheets or signatures in paper handling machines
IPC: B65H5/30
Filed: 1931-09-08
Abstract: 389,468. Stitching book signatures. POLLAK, J. E., 20, Holborn, London.- (Brehmer Maschinen-Fabrik, Geb. ; Plagwitz, Leipsic, Germany.) Sept. 8, 1931, No. 25234. [Classes 89 (iii) and 112.] Folded sheets or signatures are opened so as to engage straddlewise over the saddle or conveyer of a stitching-machine, gathering- machine, or the like by applying pressure along the fold, whilst the signature is moving towards the stitching or other machine in a direction parallel to the fold. The signatures S are fed from a pile 10 with the fold uppermost, by endless-conveyer bands 23, 24 which are carried by pulleys 25, 26 on vertical stub-shafts on a table 16 and grip the signature some distance from the fold. Adjustable brackets 28 on the table carry a spindle 29 on which is adjustably fixed an inclined V-shaped member 30 adapted to exert pressure on the folded edge of the signature as the signature is fed forward by the belts 23, 24. The oscillating saddle 12 of the stitching-machine is formed with a tapering nose 12a which engages the bulged-out fold in the signature and completes the opening of the signature. A bracket 32 fixed to the table 16 carries a series of rubber-faced, replaceable rollers 33 geared together and driven from the driving-gear 27 of the belts 23, 24, the rollers 33 co-operating with rollers 34 carried by the saddle and projecting through slots therein so as to complete the forwarding of the signature. An adjustable stop 37 limits the movement of the signature. The table 16 is carried by arms 17 fixed to a shaft 18 coaxial with the shaft 14 about which the saddle 12 oscillates, the shaft 18 being operated by an eccentric 22 so that it partakes of part of the movement of the saddle 12 thus allowing signatures to be fed more quickly. Further, the table 16 may be adjustable vertically so as to vary the distance from the fold to the point where the conveyers 23, 24 grip the signature. In a modification, the table 16 is fixed and an auxiliary saddle separate from but coaxial with the saddle 12 is provided, the auxiliary saddle being either movable partly with the main saddle or, if feeding to the carrier saddle of a rotary-wing stitching-machine, fixed. The table 16 may be reciprocated vertically so as to raise the signature until its fold abuts against a horizontal bar adapted to press open the fold, a stitching-bar or other member being then introduced into the fold space to carry the signature to the stitching or other machine. In a further modification, particularly for use with a signature-gathering conveyer, the fixed member 30 may be replaced by an oscillating-member operated electromagnetically by the engagement of the front edge of signature with a spring-controlled lever which closes an electric contact.

Title: Process for the conversion of hydrocarbon oils
Filed: 1938-08-30
Abstract: 507,389. Cracking acid coking oils. UNIVERSAL, OIL PRODUCTS CO. Aug. 30, 1938, No. 25432. Convention date, Sept. 13, 1937. [Class 32] In a multi stage process for cracking and optionally coking oils, the gasoline produced in the process is stabilized, a cooled condensate produced in the fractionation of the cracked vapours, is used to absorb rich gases set free in the stabilization and the thus enriched condensate is fed as cooling medium to one or more points in the cracking system between. the conversion zone and the fractionation zone. Crude oil is fed by a pump 54, according to its character, direct to coil 1, coil 6 or into the tower 30 where the vapour products of the process are fractionated to recover (a) gasoline fractions fed through line 61 and cooler 63 to receiver 60; (b) a side cut taken off through line 36 and flashed in tower 38 ; (c) reflux collected at the bottom of tower 30. Fractions (b) and (c) are cracked in coils 1 and 6 respectively and the products passed in part into the top of reactor 5 from the bottom of which the cracked products pass through lines 13, 17 into the coking vessel 19 and/or into the evaporator 16. The materials in the vessel 19 are reduced to coke with the aid of part of the hot vapours from coil 6 fed through line 10 and the vapours thus formed are passed into the evaporator 16 where they are cooled and freed from entrained particles by a portion of condensate (b) from tower 38. This condensate is first used as absorbent oil in tower 69 to which the gases separated in the receiver 66 are led for absorption, the condensate being fed through lines 47, 100 to the tower 69 and thence through lines 111, 113, 115 to the evaporator 16 and in part to the line 13. Residues from the evaporator 16 are removed for use as fuel oil or recycled to the coking vessel 19, while the vapours formed pass through line 28 into the tower 30. The gasoline collected in receiver 66 is stabilized by heating it in heat-exchanger 77 and passing it into stabilizer tower 80, the stabilized products being removed at the bottom of the tower through line 82 and passed through the heat-exchanger 77 to storage. Volatile fractions removed from the top of the tower 80 through line 84 are passed through a cooler 86 into a separator 89 from which gases are passed through line 95 to the absorber tower 69 while condensate is recycled to the tower 80, which may be heated by passing condensate from the tower 38 through a coil 81. The products from the coils 1, 6 are injected into the reactor 5 so as to spray the walls.

Title: Diazotisation method for the esters of aminobenzoic acids
Filed: 1948-09-30
Abstract: Diazotized esters of aminobenzoic acids are produced by diazotizing an amine salt (preferably the sulphate) of the aminobenzoic ester in a substantially non-alcoholic aqueous solution at a starting temperature of -18 DEG  C. or below produced by means of an internal refrigerating mixture.  The diazotization is advantageously effected by mixing the amine salt with ice and an acid, and then adding a nitrite, while stirring the mixture and in as short a time as possible consistent with not allowing the temperature of the final diazotized mixture to rise above 0 DEG  C. In an example, methyl anthranilate sulphate is stirred with a mixture of ice and dilute sulphuric acid, an aqueous solution of sodium nitrite is added, stirring is continued, and, if necessary, precipitated sodium sulphate is separated by centrifuging.
