Title: Method of polymerizing substituted butadienes
IPC: C08F36/04
Filed: 1957-01-02
Abstract: Butadiene-1,3 hydrocarbons substituted in the 2-position are polymerised in the presence of a lithium alkyl, cycloalkyl, alkaryl or aryl and metallic lithium.  Specified monomers are isoprene, 2-ethylbutadiene, 2-propylbutadiene and 2-phenylbutadiene ; isoprene may also be copolymerised with butadiene.  The polymers have at least 90% cis-1,4-configuration. The hydrocarbon lithium may be derived from propane, butane, pentane, hexane, octane, propylene, butene, pentene, benzene, toluene or xylene, and hydrocarbon polylithiums may be used.  Up to 0,5 gram mole of hydrocarbon lithium per gram atom of lithium is used, the amount of lithium, which is preferably finely divided, being 0,05-0,3 part per 100 parts of monomer. Temperatures of 5 DEG -70 DEG  C. are specified.  The monomer should be free of oxygen-, sulphur- and nitrogen-containing materials, and polymerisation should be effected in an inert atmosphere. Solvents in amounts of 1/2 to 20 parts by volume per volume of monomer may be used, specified solvents are propane, butane, pentane, hexane, petroleum ether, octane, kerosine, diesel oil fractions, Fischer-Tropsch hydrocarbons, petroleum oils, petrolatum, benzene, toluene, xylene and cyclohexane.  The catalyst may be removed from the polymer by means of a non-solvent for the polymer such as methanol or acetone, and acidic aqueous washes may be applied ; where lithium metal is present this is destroyed by means of an alcohol. Examples illustrate the use of amyl lithium and amyl- or butyl-lithium with lithium metal in polymerising isoprene alone and with butadiene.

Title: Manufacture of halogen alkylamines
Filed: 1936-01-02
Abstract: Halogenalkylamines are manufactured by treating oxyalkylamines or their N- or C-alkylated or arylated derivatives, after conversion into salts, with gaseous hydrogen halide at a temperature above 100 DEG  C.  The process is preferably carried out at atmospheric pressure and with continuous distillation of the water formed.  As starting materials may be employed primary oxyalkylamines, further substituted amines which may contain several oxyalkyl residues or hydroxy groups, also the N- and C-alkylated or arylated derivatives of these amines or their substitution products; e.g. 1 : 2-, 2 : 1 - and 1 : 3-oxypropylamine, triethanolamine, ethylethanolamine, phenylbutanolamine and 1 : 4-dioxy-2-aminobutane.  The products may be employed for introducing aminoalkyl residues into organic compounds or for producing cyclic imines.  In examples: (1) ethanolamine hydrobromide is treated with gaseous hydrogen bromide at 140--190 DEG  C. to yield bromethylamine hydrobromide; (2) chlorethylamine hydrochloride is produced from ethanolamine hydrochloride and gaseous hydrogen chloride at 140--220 DEG  C.; (3) butylethanolamine is converted, by the action of gaseous hydrogen chloride below 80 DEG  C., into its hydrochloride, which is treated with gaseous hydrogen bromide at 130--180 DEG  C.; (4) N-butylethanolamine is treated with gaseous hydrogen iodide while gradually raising the temperature to 150 DEG  C., yielding N-butyliodoethylamine hydriodide; (5) diethanolamine is treated with hydrogen bromide below 100 DEG  C. and the hydrobromide is treated with hydrogen bromide at 160--170 DEG  C. to produce dibromodiethylamine hydrobromide; (6) N-methylethanolamine hydrochloride is treated with hydrogen chloride at 160--180 DEG  C. to yield N-methylchlorethylamine hydrochloride; (7) N-phenylethanolamine is converted, by the action of gaseous hydrogen bromide at 100 DEG  C., into the hydrobromide, and the temperature is then raised to 150--160 DEG  C., producing N-phenylbromethylamine hydrobromide.

Title: Toy vehicles
IPC: A63H17/02
Filed: 1976-01-06
Abstract: 1528841 Toy motor cars, &c. IDEAL TOY CORP 6 Jan 1976 [8 Jan 1975] 00305/76 Heading A6S A toy motor car, &c. comprises a chassis and a body in several parts releasably connected together, impact of the car with an obstruction actuating a latch so that one of the body parts is propelled off the car and the others follow one after the other. As shown, a toy car 10, Fig. 3, consists of a chassis 14, a first body part 28 dropped onto the chassis and frictionally engaging pegs 56, a second body part 30 lying in a recess 58 in the first and having a tab 60 slotted into a hole 62 in the first, and a third body part 32 simulating the car bonnet and similarly lying in a recess 56 in the second with a tab 68 fitted into a slot 70 in the second body part. A downwardly depending latch stud 74 on the third body part is engaged in a keyhole slot 84 on the inner end of a bar 42 axially slidable in the chassis and spring-biassed to a forward, latching position retaining the stud 74, and hence the body parts 32, 30, 28, to the chassis 14. The latch stud 74 includes a spring-biassed sleeve tending to push the third, top body part 32 upwards and away from the chassis 14, &c. If the motor car strikes an obstruction, an angled bumper bar 130 is forced back on impact, sliding the bar 42 with which it is integral towards the rear of the chassis 14 so that the keyhole slot 84 releases the latch stud 74. The spring-biassed sleeve in the latch stud 74 then raises the car bonnet 32, Fig. 2, which in turn raises the second body part 30, in its turn followed by the first, main body part 28. The car thus appears to break up. A pivoted latch 108, Fig. 3, can if desired be turned to retain the bonnet 32 on the car and prevent its release when the car strikes an obstruction. The toy car is powered by an inertia wheel motor driving only the right-hand rear wheel 16, Fig. 1. To rotate the inertia wheel of the motor car 10, it is placed on a hand-cranked winder 22, &c., which drives through gearing to the right-hand rear wheel 16. When the cranking of the winder 22 is stopped the motor car 10 moves rapidly off and, since only its right-hand wheel 16 is powered, turns sharply to the left.

Jan.6, 1966, No.602/66. Heading C7B. A band or foil of copper is formed by electrodeposition on a drum cathode and is then thickened by electro-depositing copper on both sides by passing it between one or more pairs of anodes and agitating the electrolyte by passing air-streams on both sides of the band or foil. Typically a band of thickness 0À04 to 0À08 mm. is formed by electro-deposition from a copper sulphate solution at a current density of 15 to 25 amps/sq. dm, the thickness is increased to 0À4 to 0À8 mm. by passage in a series of loops formed by running alternately over current-carrying contact rollers and immersed insulated rollers at a current density of 7À5 to 15 amps/sq. dm, and finally the thickness is increased, e.g. up to 10mms, by deposition from an alkaline copper electrolyte at a current density of 5 to 10 amps/sq. dm by passage in a straight line between one or more pairs of parallel anodes. If desired passage through the loop-form electrolyzer may be omitted if a final band thickness of only 2 to 4 mms. is required. The copper sulphate electrolyte which may be used at 30 to 70‹ C. may be circulated from the electro-forming drum cathode apparatus to the loop-form electrolyzer from which it is returned to the electro-forming apparatus after replenishment of the copper content.

Title: Improvements in and relating to feed regulators for steam boilers
IPC: F22D5/10
Filed: 1926-01-12
Abstract: 248,335. Torre, E. Feb. 25, 1925, [Convention date]. Feedwater, supplying and controlling. - The feedwater supply of a marine, boiler is controlled automatically by a float located in a water-level vessel which communicates through valve-controlled tubes N, M with the steam and water spaces of the boiler respectively. The bottom of the float is formed with an aperture, while to the top is secured a tube which communicates with the steam space of the boiler and which is connected through links with a needle-valve which controls the escape of water from the space beneath a loosely-fitting piston S forming a continuation of the feed valve D, the space between the valve and the piston communicating with the feed pump. When the water level in the boiler falls, the weight of the float closes the needle valve so that the water is unable to escape from the space beneath the piston, the consequent rise of pressure opening the valve D and forcing the water into the boiler. When the water level rises, the steam enclosed between the vessel and the float condenses and the float rises, thus opening the needle-valve and relieving the pressure beneath the piston and allowing the feed valve D to close. In a modification, the tube secured to the top of the float is continued downwardly and terminates in a balanced valve which controls the pressure beneath the piston. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an automatic feed regulator consisting of a water-level vessel 1, Fig. 3 (Cancelled), communicating with the steam and water spaces of the boiler and having an open-ended pipe 2 one end of which reaches to the normal level of the water in the vessel, while the other communicates with the feed-tank 3. The partial vacuum intermittently produced in the tank by the alternate covering and uncovering of the end of the pipe in the vessel controls the water-level in the boiler. This subject-matter does not appear in the Specification as accepted.
