Title: Springs of iron-nickel-cobalt alloys and more particularly stainless springs for watches
IPC: C22C19/05
Filed: 1948-04-19
Abstract: Butadiene is separated from hydrocarbon mixtures which may also contain compounds such as hydrogen sulphide and mercaptans by washing with a cuprous salt solution, and thereafter heating the solution in three stages at successively increased temperatures, hydrocarbons released in the first and second stages being returned to the washing zone, and butadiene collected from the third stage.  A C4 fraction is freed from acetylene and fed upwardly in liquid phase against a downward stream of a cuprous salt solution, such as cuprous chloride and hydrochloric acid, cooled to about 10 DEG  F. although temperatures of 0-75 DEG  F. may be used.  Pressures up to 30 lbs./sq. in. are maintained.  The solution passes to a partial desorber at 30-60, preferably 47 DEG  F., and a pressure such that no condensation of hydrocarbons occurs.  The freed gases consisting of butenes and butadiene are washed to remove ammonia or other impurity, and are returned to the absorber.  The cuprous solution passes to a second desorber at a temperature of 40-75, preferably 54 DEG  F.  The liberated gases are returned to the absorber after washing as before, while the solution is heated to 100-250, generally 160 DEG  F., and passed to the final desorber.  Substantially pure butadiene is evolved, and the solution is returned to the absorber.  The absorption solution may alternatively consist of cuprous chloride, monoethanolamine, the hydrochloride of the base, and water cooled to 0-90, preferably 50 DEG  F.  The desorption is effected at 60-90, 100-150 and 150-180, or as high as 200 DEG  F.  Pressures may be up to 4 atm. during absorption and 2-0.2 atm. for desorption.  Other absorbent solutions specified comprise cuprous chloride with monoethanolamine and ethylene glycol, monoethanolamine, ammonium chloride and water, or formamide, hydrochloric acid and water, the same temperatures being used in the desorption stages. Specification 547,730 is referred to.ALSO:Stainless springs, particularly for watches, are made of an alloy of the following composition:-Fe 10.0-20.0 per cent, Ni 10.0-47.6 per cent, Co 21.0-50.0 per cent, Mo 6.1-10.0 per cent, Cr 10.0-18.0 per cent, W 4.0-10.0 per cent, Be 0.05-3.0 per cent, Ti 0.1-3.0 per cent, C 0.05-0.6 per cent, Mn 1.0-6.0 per cent, Si 0.1-1.0 per cent, V 0-6.0 per cent, Cu 0-6.0 per cent, Al 0-6.5 per cent, the total of Cr, Mo and W not exceeding 30 per cent, the total of Be, Ti and C not exceeding 5 per cent and the total of Mn, Si, V, Cu and Al not exceeding 8 per cent.

Title: Production of phenolic compounds
IPC: C07C37/50
Filed: 1943-07-05
Abstract: Mono- or poly-hydroxy phenolic compounds are obtained by pyrolysing a ketone containing at least one cyclic non-aromatic nucleus of six carbon atoms in the vapour phase in the absence of a catalyst at a temperature below that at which excessive nuclear degradation of the ketone occurs, preferably one between 575 DEG  C. to 750 DEG  C. and for a contact time not exceeding 10 seconds. Advantageously; isophorone is pyrolysed to 3,5-dimethyl phenol at 640 DEG  C. to 675 DEG  C.

The homo-isophorones are converted into phenols containing at least two alkyl groups, viz., those in the 3- and 5-positions, although other alkyl groups may also be present according to the starting material chosen.  Other specified conversions are: pulegone to thymol, isopulegone to 5-methyl-2-isopropenyl phenol, carvenone to 2 - methyl - 5 - isopropyl phenol and o-cresol, carvone to 2-methyl-5-isopropyl phenol, 2-methyl-5-isopropenyl phenol and o-cresol, methone to 2-methyl-5-isopropyl phenol and o-cresol, cyclohexanone to phenol, a , g -bis-(2-keto-4-methylcyclohexyl)-propane to a , g -bis-(2-hydroxy-4-methylphenyl)-pro-pane, 1.5-diketo-1.2.3.4.5.6.7.8-octahydronaphthalene to 1.5-dihydroxy-naphthalene diketotetrahydro-naphthalenes to dihydroxy naphthalenes, g -dicarvelone to g -dicarvacrol (i.e. 2.21-bis-carvacrol), Bucco camphor to 3-methyl-6-isopropyl catechol. Other specified starting materials are diosphenols in general, their homologues and substituted derivatives.  The methyl groups in isophorone and similar substances may be substituted by any alkyl radicals such as ethyl, propyl, isopropyl, butyl, isobutyl, amyl, hexyl and heptyl.

A blow-moulding apparatus includes two movable moulds 5, 6 arranged so that one mould is in a charging position 7 in which it can be charged with a material to be moulded from above whilst the other mould is in a discharge position 8 in which the formed article can be discharged and which is inverted with relation to and substantially vertically beneath the mould in the charging position and means for moving the moulds between the charging and discharging positions. The moulds 5, 6, which may be multi-cavity, comprises mould halves 5<SP>1</SP>, 5<SP>2</SP>, 6<SP>1</SP>, 6<SP>2</SP> associated with double-acting fluid pressure motors 5<SP>3</SP>, 5<SP>4</SP>, 6<SP>3</SP>, 6<SP>4</SP> for opening and closing the moulds, the operation of the motors being so synchronized that the discharge of fluid from one motor is used to operate another. The moulds with their motors are mounted on a carrier, formed of side plates 1, 2 on a horizontal spindle 3, supported for oscillatory movement of 180 degrees between charging and discharging positions. The carrier is moved by power-operated means controlled by a photo-sensitive device which responds to the movement of the charging material when entering the mould. The spindle 3 has a boss 10 which carries a double-ended blowing nozzle 11 which is arranged to move such that whilst one end is in a closed mould blow moulding an article, the other end is retracted from an open mould and may be being used in ejecting the finished article by blowing it out of the mould, and may also be rotated and fixed at any angle independently of the moulds for use with bottles with angled or offset necks.

Title: Process for the purification of alkaline-earth metals by distillation at reduced pressure
IPC: C22B26/20
Filed: 1957-04-09
Abstract: Alkaline-earth metals are distilled by forming a liquid layer of an alloy of lower melting point than the metal to be purified on the outside of a solid lump of the metal in a vessel under vacuum (10-1 to 10-3 mm. Hg.).  Vaporization under reduced pressure then occurs from the superficial molten alloy layer above which the vapour pressure of the alkaline-earth constituent is greater than that of the alloying constituents, most of the metal to be purified remaining solid beneath the thin liquid alloy layer.  The alloying constituent may be in the form of foil which is wrapped round the lumps of alkaline-earth metal or as a powder applied to the surface of the lumps Suitable alloying metals are aluminium, copper, tin, lead, nickel and cobalt or mixtures of these and are added in amounts up to 5 per cent. of the weight of the alkaline-earth metal.  In an example, 20 kg. of crude calcium were alloyed with 0.5 kg. of aluminium and distilled at a temperature of 750/800 DEG C. and a pressure of 10-2 to 10-3 mm. Hg.

[Class 27] Coin-action, thrust, with delivery proportionate to value of coin. -The mechanism described in the parent Specification is modified by the provision of a stopmember mounted on the coin-pocket for limiting the first movement of the coin actuated element k when a coin smaller than that for which the slot is intended is inserted, so that full insertion of the coin is prevented. The stop member may, as shown, comprise a plate m pivoted at d<3> to the pocket, and have abutments m<2> engaging the carrier plate b for limiting its movement. When an undersized coin is inserted, a hooked part m<1> on the plate m engages a pin k<8> on the element k so that full insertion is prevented, and the coin is ejected as described in the parent Specification. When a correct coin is inserted, the element k is engaged by the coin near its pivot point k<1> and slides vertically, carrying with it the striker g, so that the pin k<8> clears the hook m<1> permitting the element k to turn about its pivot k<1> and receive the coin wholly within the pocket, and in a position in which it is not ejected. The stop member m is moved about its axis by the pin k<8> against the action of a spring m<3> to permit return of the element k after the coin is discharged. Modifications are referred to in which the stop m takes the form of a spring-actuated plunger or a slotted plate. Specification 400,636 is referred to.
