Title: Process for crystallizing urea
Inventor: ROSENBLOOM WILLIAM JACOB
IPC: C05C9/00
Filed: 1966-03-28
Abstract: Crystalline urea of low biuret content is obtained by removing urea crystals from a crystallization zone in a slurry having a mother liquor high in biuret content, passing the slurry vertically downward in an elutriator in countercurrent flow to an upward flow of an aqueous solution of urea of low biuret content, separating the crystals from the mother liquor and passing the slurry after the countercurrent flow from the upper portion of the elutriator to the crystallization step.  A subatmospheric pressure may be maintained over said aqueous solution containing urea and biuret during the crystallization which may be effected at 130-160 DEG  F., and the rising liquid phase during countercurrent flow is suitably maintained at 130-200 DEG  F. The mother liquor of the slurry from the initial separation may be combined with make-up urea solution low in biuret content and recycled to the countercurrent flow.

Title: Improvements relating to shock absorbers for the forks of cycles or like vehicles
IPC: B62K25/24
Filed: 1951-06-08
Abstract: 720,093. Cycle fork shock absorbers; mud guards. SOC. FRANCAIS DE MECANIQUE ET PIECES DETACHEES, S.F.M.P.D. June 8, 1951 [Aug. 8, 1950], No. 13714/51. Classes 136(1) and 136(3). A shock absorber assembly for the forks of cycles or like vehicles consists of a link pivotally connected between its ends to the fork head and at one end to the frame, at least one casing in which the fork head can freely slide and which is pivotally mounted on another point on the frame, so as to take up variable inclinations as a function of the reactions of the fork, and at least one bi-directional shock absorber connected between the other end of the link and a lug fixed at the lower end of the casing. As shown, a bicycle front fork consists of a pair of tubes 20 each slidable in a casing 22. The two casings 22 are bridged by cross-pieces 23, 24 to the lower of which is welded a pair of oppositelyextending lugs 25, 26, lug 25 being pivoted to the steering column 1 at 7. A bracket 4 on the upper part of column 1 supports pivoted to it at 5 a pair of co-extending links 8 joined at their outer ends by a pin 9. The tops of fork tubes 20 are pivoted to links 8 at 34. A shock absorber is connected between the pin 9 and a pin 19 on lug 26 and consists of a piston 11 working in a sealed cylinder 12 and damped pneumatically, having springs 15, 16 on either side for urging it to a neutral position in the cylinder, spring 15 being stronger than spring 16. In operation the fork tubes slide in the casings 22 so as to act on the shock absorber and since this alters the angle between the links 8 and lugs 25, 26 the casings tilt towards and away from the steering column during such sliding. Forward and rearward shocks on the fork consequently cause sliding of the tubes 20 in casings 22 and are thus damped in addition to vertical shocks. Mud-guards. These are attached to the fork by a bridge piece 29 secured by a long bolt 27 between lugs 28 on the tubes 20. A lug 30 welded on the piece 29 is drilled for reception of a bolt for securing the mudguard to it.

Title: Improvements in or relating to the manufacture of combustible gas
Inventor: HAWES JACK MALCOLM
IPC: C01B3/40
Filed: 1961-04-18
Abstract: A process for maintaining the activity level of a nickel catalyst bed when used for catalytic cracking of gaseous or liquid hydrocarbons with steam or with steam and air, especially in cyclic processes, comprises feeding a hydrocarbon solution of a hydrocarbon-soluble salt of an organic acid into the plant during gas-making simultaneously with the injection of the hydrocarbon feedstock, the said introduction being carried out either continuously throughout all periods of injection, or intermittently during part of each or any period of injection of the feedstock.  The salt is decomposable under the operating conditions to produce nickel or nickel oxide together with other compounds similar to those produced by cracking the feedstock. The nickel salt may be the nickel salt of a fatty acid having from 7 to 17 carbon atoms in the hydrocarbon chain or of an alicyclic carboxylic acid having 5 carbon atoms in the ring, e.g. nickel oleate, nickel myristate, nickel linoleate, or a nickel salt of a naphthenic acid.  The nickel salt may be dissolved in the feedstock or added thereto in solution, or may be separately injected as a solution on to the catalyst.  The amount of nickel added amounts to 0.002% to 0.05% by weight of the feedstock in a given phase, and delivery of the solution may be automatically controlled from the gas-making plant.  Specification 772,787 is referred to.

Abstract: 1,087,115. Spray-producers. REGIE NATIONALE DES USINES RENAULT. April 2, 1965[April 3, 1964], No. 14023/65. Heading B2F. [Also in Division F1] An oil atomising apparatus for blowing intermittently and alternately onto the place where a cutting tool of a metal working machine attacks the metal, first a mixture of air and oil and then air alone comprises a compressed air supply conduit 3 adapted to be connected to an intermittent compressed air source 27 and communicating with a conduit 5, for discharging atomised oil and air, through a passageway 4 of reduced section. A pneumatically-controlled valve 6 has a control chamber 14 which communicates with the conduit 3 and is closed by part of a rubber diaphragm 26. The latter cooperates with a seat 17 formed within an oil-passing chamber 15 the diaphragm being biased into a position such that a passageway 9 through the seat 17 and communicating with a working chamber 19 of a pneumatically-controlled reciprocating pump 8 is normally open. The oil-passing chamber 15 is adapted to be connected to an oil supply source through a conduit 7 whilst a control chamber 18 of the valve 8 is connected to the air supply conduit 3 through a conduit 20. The chambers 19 and 18 are separated by part of the rubber diaphragm 26 and a spring 21 continuously urges such diaphragm part towards the chamber 18. Through the medium of a conduit 11, a delivery valve 10, and a conduit 13 the chamber 19 communicates with an oil spray nozzle 12 disposed in the conduit 5. In operation, the intermittent compressed air supply to the conduit 3 causes the pump 8 to reciprocate thereby sucking oil into the working chamber 19 during one cycle and ejecting it into the air stream in the conduit 5 during the next cycle. When all the oil in the chamber 19 has been atomised compressed air continues to be ejected for a time dependent upon the actuation of the mechanism causing cut-off of the compressed air supply. By this means swarf produced by the cutting is cleared away. The apparatus is constructed of two moulded and machined plastic or metal units 1, 2 clamped together by blots with the diaphragm 26 therebetween.
