Title: Lock
IPC: E05B37/08
Filed: 1949-09-21
Abstract: 651,187. Permutation locks. SARGENT & GREENLEAF, Inc. Sept. 21,1949, No. 24296. Convention date, March 26. [Class 441 In a permutation lock of the type comprising a series of coaxial discs set to align peripheral notches by movements of a central control knob, a sliding bolt 23, Fig. 2, is adapted to be withdrawn by a lever 24 pivoted thereto, having a nose 28 to engage in a recess 12a in the wheel 12 connected to the control knob 13, Fig. 1, by a sleeve 11 and driving the discs 6, 7 and 8. A cross bar 27 on the lever 24 is arranged to enter the aligned notches in the discs as the nose 28 engages the recess 12a, but this movement can be prevented by displacement of a slider 43 mounted on the face of the driving wheel adapted to bridge the notch 12a in one position and in the other position to project a tail piece 43d outside the circumference of the driver wheel 12 to engage stops 60a, 60b to limit the rotation. The slider is formed with arcuate ends so that when in the bridging position the driver 12 presents a smooth circumference to the nose 28 main taining the bar 27 out of contact with the discs. The slider is displaced by a gear wheel 46 engaging a rack 44 formed in an opening in the slider and controlled through the spindle 47 by a key or permutation lock. In operating the lock, the shaft 47 is first turned, e.g. by the key 53 shown in Fig. 1, to set the slider 43 in the bridging position, withdrawing the end 43d to permit full rotation of the driver 12. A lug on the driver engages a projection on the disc 8 which is similarly connected to the next, 7, and that to the last 6 so that the discs are successively set by to and fro rotation of the knob 13. When the discs and the driver are all correctly set the key is turned to move the slider so that the nose 28 engages in the notch 12a and rotation of the knob will then withdraw the bolt. The distance between the stop faces 60a, 60b is sufficient to allow this rotation when the tail 43d is projected. As a further protection against picking the discs are serrated at 100 and co-operate with serrations 101, Fig. 11, on the bar 27. A slightly flattened portion on the circumference of the driver 12 allows the bar 27 to engage the discs when the nose 28 is in this position. To frustrate any attempt to open the lock by forcing the spindle inwards, a rocker 31, Fig. 2, pivoted at 33 normally to retain a spring plunger 34 retracted, but arranged to release the plunger for engagement in a socket of the bolt on inward displacement of the lock spindle 11. In a modification, Fig. 11, the slider 73 (shown in the bridging position), is mounted between guides on the driver 72 and displaced to either position by a cam member 84 engaging in a shaped opening 83. It is retained in the bridging position by a ball catch 77.

Title: A process for the catalytic alkylation of hydrocarbons, alcohols, organic acids and amines
IPC: C07C15/00
Filed: 1929-08-08
Abstract: 319,205. Rheinische Kampfer Fabrik Ges. Sept. 17, 1928, [Convention date]. Hydrocarbons; alkylated amines, esters, ethers. - Hydrocarbons, alcohols, organic acids and amines are alkylated or aralkylated by reacting with unsaturated hydrocarbons (or bodies capable of yielding such unsaturated hydrocarbons) by the action of activated hydrosilicates or of silica obtained therefrom. The activated hydrosilicates are made by heating with acids, bleaching earths,. clays, kaolin and the like; for instance kaolin may be heated at 100-120‹ C. for several hours with 25 per cent sulphuric acid, or bleaching earth,. kaolin and the like may be treated to produce silica by prolonged heating with strong hydrochloric or sulphuric acid at 100-120‹ C., the product being washed and dried. The hydrocarbons such as propylene mav be united with carboxylic acids such as benzoic acid to produce esters and an alcohol may be converted into an ether by heating with the catalysts; also ammonia, aliphatic and aromatic amines mav be alkylated, for instance bv heating with ethylene, and a migration of the alkyl group to the nucleus in aromatic compounds may take place. Instead of a hydrocarbon, an alcohol or ether such as ethyl or methyl alcohol or ether or cyclohexanol may be used. In the examples (1) naphthalene is heated in an autoclave at 250‹ C. with an activated bleaching earth such as " tonsil " and ethylene is forced in at 20-40 atmos., yielding polyethyl naphthalenes: (2) cyclohexanol and benzene are heated with " tonsil " to yield cyclohexylbenzene; (3) benzyl alcohol and benzene are heated with " tonsil " yielding diphenylmethane and other isomers; (4) ethyl alcohol vapour is passed at 150-200‹ C. over activated bleaching earth such as " tonsil " or frankonite," yielding ethyl ether; (5) benzoic acid and " tonsil " are heated and propylene is passed in at 50-60 atmos., yielding isopropyl benzoate; (6) aniline and methyl alcohol are heated with tonsil " or aniline and methyl alcohol are passed over "tonsil." yielding dimethylaniline. The Specification as open to inspection under Sect. 91 (3) (a) states that the process may be used to alter the position of an alkyl group in the molecule, or that a compound containing more than one alkyl group may be made to part with one or more such groups to another compound containing none. According to examples, anisol and isomeric cresols are obtained from ethyl alcohol and phenol, 6-chlorthymol is obtained by isomerization of the isopropyl ether produced by treating 6-chlor-m-cresol with propylene, and diethyl naphthalenes treated with naphthalene yield monoethyl naphthalene, "tonsil" being the catalyst in each case. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in the chloridising roasting of raw materials containing iron and non-ferrous metals
IPC: C22B1/08
Filed: 1956-08-14
Abstract: In the chloridizing roasting of ferrous raw materials to convert the non-ferrous components to leachable compounds while leaving the iron in the insoluble oxide form, the roasting is carried out in a fluidized bed in the presence of alkali metals salts, under conditions such that the temperature of the bed is between 550 DEG and 650 DEG  C., preferably 610 DEG  to 630 DEG  C., the roaster gas contains between 0.1 per cent and 10 per cent by volume, preferably 0.3 to 2.5 per cent, of sulphur oxides and between 0.1 per cent and 10 per cent by volume, preferably 1 per cent to 5 per cent of chlorine and hydrogen chloride, and that a portion of the fluidized bed, not exceeding 25 per cent by weight, preferably 15 to 20 per cent, is present in the fused state due to the union of alkalimetal salts with non-ferrous metal salts.  As alkali-metal salts there can be added to the initial materials a total of 6 to 15 per cent by weight of sodium chloride, sodium sulphate, or potassium chloride, either singly or together in the form of double salts.  The amount of the bed which is in the fused state is determined by withdrawing a sample from the bed and comparing the conductivity of a portion of this sample at 300 DEG  C. with another portion of the sample at the temperature of the fluidized bed by a Wheatstone bridge method, from which the proportion which is fused may be deduced.  The temperature of the bed may be adjusted by the addition of a carbonaceous fuel to the solid, or by adding steam to the roaster gas.  The roaster gas composition may be adjusted by limiting the supply of oxygen or by adding sulphur dioxide, chlorine, or hydrogen chloride. Specification 668,119, [Group XX], and 696,003 are referred to.
