Title: Combination mechanism for locks
IPC: E05B37/16
Filed: 1945-10-19
Abstract: 601,185. Permutation locks. KETNER, L. P. G. Oct. 19, 1945, No. 27527. Convention date, Nov. 14, 1944. [Class 44] Permutation lock mechanism of the kind in which each of a number of push rods 2 carrying pins 3 have to be set in predetermined positions, comprises a series of plates 4 . . . 8 sliding laterally in guides in the casing, and actuated to operate the lock by means of a member 22 pivoted at 21. The plates 4 and 8 are plain; plate 5 has openings 24 through which the pins 3 pass, with slots 25 extending therefrom which permit movement of the plate when the pins are opposite the slots ; the plate 6 has openings 26, each having three (or more) incisions 27 corresponding to the possible positions of the pins, which during initial movement of the plates lock the pins to prevent further manipulation to open the lock by feeling. Plate 4 is a cancellation plate in which the openings 28 are shaped as shown to bring all pins to the central position on locking. The plates are moved by the member 22 through cam surfaces thereon acting on projections 19, 29, 30 on the plates. To unlock after setting the push rods, the member 22 is. turned anti-clockwise, when the plate 5 is moved to the left by contact of the ledge 20 with the projection 19 on plate 5, carrying plate 4 with it through contact of a flange 13 on the latter with the end of the plate 5. At the same time the locking plate 6 is allowed to move under the influence of a spring 17. Plates 7 and 8 remain stationary during unlocking. When the member 22 is released, it is turned counter-clockwise by pressure of the projection 19 against the edge 20, and the plates 7, 8 and 9 are then free to move to the left under the influence of a spring 40 ; the cancellation plate 7 then centralises the pins. The plate 9 is pulled to the right by the latch when the lock is again closed, and the spring 36 causes the plate 7 to move to the right and return the member 22 to the central position through the action of projections 29, 30 on the cam surfaces 31, 32. To prevent setting of the push rods by feeling, the pins 3 may be loosely fitted in the push rods 2, and guided at each end between the plates 4 and 8, and further, those parts of the push rods which project from the casing may be reduced in diameter to avoid showing wear marks that might reveal the correct setting. In a modified construction, the plates 4 ... 8 are curved to the form of concentric circles, and move in part-circular guide-ways around their common centre.

Title: Improvements in foils resisting electrification
IPC: C08J7/044
Filed: 1946-09-13
Abstract: Colourless, transparent compositions comprising polyvinyl alcohol or a water-soluble partially saponified polyvinyl carboxylic ester and an electrolyte are used to coat foils of hydrophobic film-forming material to reduce their tendency to electrify by friction (see Group VIII).  The electrolyte may be a salt of an amine such as the diethylene diamine salt of dodecyl acid sulphate, salts of triethanolamine or dimethyl-cyclohexylamine or alkylol amine salts of soap forming fatty acids such as lauric, palmitic, oleic and stearic acid, or those described in Specification 542,501.  If desired the amine salts may be used in conjunction with an aliphatic or cyclo-aliphatic alcohol containing at least six carbon atoms, such as octadecenyl alcohol, dodecyl alcohol, cyclohexanol, methyl cyclohexanol, benzyl alcohol and the mono-butyl ether of diethylene glycol.  The polyvinyl alcohols or partially saponified polyvinyl esters may be obtained by the saponification of polyvinyl esters of carboxylic acids using a process such as that described in Specifications 454,425 or 563,991.  The polyvinyl esters include copolymers such as those obtained by polymerizing a mixture of vinyl esters or mixtures of vinyl esters with vinyl chloride or acrylonitrile.  The coating composition may be applied as an aqueous solution.

Title: Wood-pulping process
Inventor: MOYE JULIUS DUCWORTH ROBERTSON
IPC: D21C3/26
Filed: 1964-07-04
Abstract: 1, 035, 397. Treating wood pulp. SONOCO PRODUCTS CO. July 4, 1964, No. 27655/64. Heading D2W. Wood chips are pulped by cooking them in a digester with a chemical liquor, conducting the free liquor to a separate tank, evaporating volatile components, e.g. water from the liquor, condensing them, returning the condensate to the digester to further treat the chips, and returning this liquor to the tank. As shown, wood chips are cooked in digester 7, using liquid, originally from tank 64, circulated through lines 19, 22 and 46, heat-exchanger 47 and line 53. After a sufficient time, the liquor is blown down lines 19 and 28 to tank 29. Vapour from the ullage 37 is withdrawn and compressed by a centrifugal compressor 39, and passed through coil 41, immersed in the tank to condense it, and then passes through lines 42, 44 and 46, heat-exchange 47 and line 53 to the digester to further hydrolyze and wash its contents. The washing liquor returns by lines 19 and 28 to tank 29 forming a closed system. When the washing is complete, the pulp can be blown down the line 17 to, e.g., paper-making machinery, and the black liquor blown up lines 28 and 26 to, e.g., storage or a burner supply. Values are installed where shown to permit the necessary connections to be made. In modifications: (1) part of the condensate is bled off at 48 to concentrate the black liquor; (2) second or subsequent cooking stages are carried out in the same digester, using liquor from tank 65, having composition different from that in tank 64, this second cook being followed by a second blow-down of black liquor and wash as before, the black liquors from the two stages being collected separately or together as desired; (3) the second cook is carried out using only condensate from the liquor from the first cook; and (4) chemical for a second cook is introduced through line 48 and carried into the digester by condensate from the liquor from the first cook. The chemicals used may be: in a single-stage process a neutral sulphite liquor containing sodium sulphite and sodium bicarbonate; or in a two-stage process first an alkaline liquor such as NaOH, Na 2 CO 3 , Na 2 SO 3  or NaHSO 3  or mixtures thereof, followed by an acid liquor in the second stage, or an acid liquor such as NaHSO 3  plus free H 2 SO 3  in the first stage, followed by an alkaline liquor in the second stage.

In a brake of the kind comprising a brake cylinder 1 arranged to apply braking effort to a vehicle brake rigging 5 through brake levers 3, 4 provided with two tie-rods 6, 7, the ends of which are pivotally connected to the levers at different points in their length, one or other of the rods being rendered operative so as to provide fulcrums for the levers to vary the leverage according to whether the vehicle is loaded or empty, the transfer from the load pivot 11 to the empty pivot 9 during braking application under empty vehicle conditions is arranged to be effected automatically when a predetermined force is exerted on the brake rigging, by the displacement of a spring-loaded abutment 31 by the load pivot 11. Fig. 1 shows the mechanism in the empty condition, an abutment 14 being arranged to contact the empty pivot 9 before the spring 12 is fully compressed. In the loaded condition (Fig. 2, not shown), the abutment 14 is pivoted to one side allowing free motion of the pivot 9 whilst an abutment 13 is pivoted into the path of the member 31 to preclude compression of the spring 12 and thus ensure use of the pivot 11 and the consequent highest leverage during load braking. Spring-loaded, toggle-acting operating levers for the abutments 13, 14 are provided, the adjustment of which may be effected manually or automatically.

Title: New unsaturated aliphatic amino-diols and pharmaceutical preparations containing them
IPC: C07C29/42
Filed: 1959-08-13
Abstract: Alkynes of the formula CH3(CH2)n-C­CH wherein n is an integer greater than 12, used as intermediates in the preparation of amini-diols (see Group IV(b)), are made by condensing an alkyl bromide CH3(CH2)nBr with sodium acetylide.  Specification 884,461 is referred to.ALSO:The invention comprises amino-diols of the formula: CH3(CH2)n-A-CH(OH-CH(NH2)-CH2OH and acid addition salts thereof, in which A is a cis or trans -CH=CH- or a -C­C-group and n is a whole number greater than 12, especially 13, 15 and 17, in the form of their threo, erythro and optical isomers and acyl derivatives for example N-acyl and N-, O-, O-triacyl derivatives thereof, wherein the acyl radical may suitably be an aliphatic carboxylic radical such as acetic or propionic.  The compounds are prepared by condensing an aldehyde CH3-(CH2)n-C­C-CHO with b -nitroethanol and reducing the resulting nitro-compound CH3(CH2)n-C­C-CH(OH) -CH(NO2)-CH2OH3 if desired after resolving into steroisomers; converting the triple bond to a double bond if desired and/or acylating and/or converting into salts and/or resolving into optical antipodes.  The reduction of the nitro group is preferably effected by treatment with zinc and hydrochloric acid or iron and acetic acid.  Conversion of the triple bond to a double bond is carried out by hydrogenation with a Lindlar catalyst or a poisoned palladium catalyst or with a di-metal hydride such as lithium aluminium hydride.  Alkyn-1-als of the formula CH3-(CH2)n-C­C-CHO are made by condensing an alkyl bromide with sodium acetylide, converting the resulting alkyne (see Group III) to its metal derivative, e.g. with ethyl magnesium bromide, treating with an orthoformic ester to give an acetal of the desired alkynal and hydrolysing.  Pharmaceutical preparations having antithrush action, fungicidal and coronary dilating properties and capable of delaying the clotting of blood, comprise the above amino-alkyne-diols or acyl derivatives thereof of the invention, or their salts such as the hydrohalide, sulphate, phosphate, perchlorate, acetate, citrate, oxalate, tartrate, ascorbate, methanesulphonate, hydroxyethanesulphonate, p-toluenesulphonate, salicylate, p-amino-salicylate or acetylsalicylate, and a pharmaceutical carrier. The products suitably take the form of tablets, dragees, powders, suppositories, solutions, suspensions or emulsions.  Specification 884,461 is referred to.
