Abstract: 551,987. Slings: lifting and lowering. STONE & CO., Ltd., J., and HATCHER, E. C. Aug. 15, 1941, No. 10390. Addition to 542,775. [Classes 78 (ii) and 78 (iv)] [Also in Group XXI] An improvement in or modification of the invention of the parent Specification comprises the use of external hand- or power-actuated means other than a spring, for winding in the bomb slings after release of the bombs. The drum b has three grooves for sling cables c, the free ends of which are provided with an eye device c<SP>1</SP> which is engaged by a releasable catch device on the aircraft when the slings are drawn out and passed around a bomb. The drum may be formed in two portions adapted to be fitted together to enclose enlarged portion u on the ends of the cables c and is splined to a shaft e mounted in a bearing f at one end of a casing a, and in a hub-sleeve g<SP>1</SP> of a gear wheel g at its other end. The casing is pivotally mounted on the aeroplane by a pin d. A hand-wheel j is splined to the shaft e at one end for the purpose of rotating the drum to wind in the cables. A clutch ring k is attached to one side of the drum by screws and shear-pins k<SP>2</SP>, and is formed with ratchet recesses k<SP>3</SP> adapted to co-act with dogs g<SP>2</SP> formed on the face of gear g. A compression spring maintains the clutch,in engagement but the clutch may be disengaged by sliding the hub-sleeve and gear outwardly, until a spring stop v in the casing engages w in the sleeve, which retains the clutch against reengagement. In this position, the gear wheel g is also disengaged from a pinion n on a shaft n<SP>1</SP> adapted to be rotated through irreversible screw gearing o, p from a shaft p<SP>1</SP> driven through a pretensioned slip-device t and a friction held hand-wheel q, Fig. 4. When the clutch k is disengaged, the slings may be pulled outwardly of the casing to pass around the bomb as the drum is then free. The slings are then tensioned by re-engaging the clutch and rotating the drum through the gearing and clutch from the hand-wheel q. After release of the bomb, the slings can be rewound by the hand-wheel j, the teeth of the clutch passing over each other by compression of the spring 1. The slings may be rewound automatically by an electric motor and gearing, automatically controlled by the dropping of the bomb or by means of a drum and cord, one end of the cord being attached to the bomb and the cord breaking after the slings are rewound. The clutch may be held in engaged or disengaged position by an electromagnet, in which case the locking pin v can be dispensed with, and with this arrangement the clutch may be disengaged during the rewinding of the slings.

Patent GB-561337-A (GB)
Title: Improvements relating to synthetic resins and their uses
IPC: C08F8/26
Filed: 1942-07-29
Abstract: Modified resins which are thermoplastic are obtained by removing halogen from polymers containing a -chlor or a -brom-acrylic acid units.  Preferably the polymer is heated in the presence of a primary or secondary alcohol.  The process may be carried out by hydrolysis with water in the presence of the alcohol.  A mineral acid catalyst may also be present.  Specified starting materials are homopolymers of a -chlor and a -brom-acrylic acid and copolymers of them with methyl methacrylate or styrene or a vinyl ester, e.g. acetate.  The primary or secondary alcohol is preferably monohydric and specified monohydric alcohols include alcohols of the general formula CnH2n+1CH2OH (n=1 to 5).  Methyl, isopropyl, lauryl and benzyl alcohols are also mentioned.  The modified resins can be formed into films and sheets suitable for use as supports for photographic emulsions or as interlayers for safety glass.  Films may be cast from solutions in acetone, 1.4-dioxane, ethyl acetate, the monoethyl ether of ethylene glycol or mixture of acetone and methyl alcohol or ethylene chloride and acetone or methylene chloride and ethyl alcohol.  The resins are compatible with various plasticisers: a long list is given. Examples are given of the hydrolysis of poly a -chloracrylic acid by means of aqueous n-primary butyl, methyl, ethyl, propyl, hexyl, lauryl, isopropyl and benzyl alcohols. Examples are also given of the treatment of copolymers of a -chloracrylic acid with methyl methacrylate, vinyl acetate and styrene, and of polymers of a -brom-acrylic acid.  An example is given of a film obtained by casting a solution of a resin obtained by hydrolysing poly a -chlor-acrylic acid with aqueous n-primary butyl alcohol, in acetone and di(b -ethoxyethyl) adipate.  This butyl resin dissolved in acetone alone was also spun into filaments.  The lauryl resin was extracted by "Skellysolve G," a mixture of low-boiling saturated hydrocarbons.

Title: Photographic processes and materials therefor
IPC: G03C7/30
Filed: 1944-06-02
Abstract: 581,790. Photographic sensitive material; colour photography; kinematograph pictures and sound films. KODAK, Ltd., KNOTT, E. B., and STEVENS, G. W. W. June 2, 1944, No. 10663. Addition to 581,772. [Class 98 (ii)] The invention of the parent Specification is modified in that a sensitive material comprising silver salt emulsions respectively of the Types I and II specified therein, either coated in superimposed layers or mixed, and having the same gamma, is exposed to produce latent images in both emulsions simultaneously, and is thereafter developed first in a surface-image developer and then in an internal-image developer, such developers being those specified in Formulµ II (b) and III of the parent Specification ; either or both may be colour developers ; and the two developing steps may be controlled so as to give a desired shade in a particular colour range. The invention includes also sensitive material for carrying out the method. Material consisting of, e.g. two red sensitive emulsions may be used to produce a coloured colour-correcting mask for use in colour photographic reproduction as described in Specification 568,440 by exposing it to the multi-colour original, developing one image with a surface developer containing a yellow-forming colour coupler and the other with an internal developer containing a magenta-forming colour coupler, and removing the developed silver from the images. Or the material may be used for producing picture films provided with a marginal sound track of lower gamma than that of the pictures by producing-latent. picture and sound images therein, developing both in a surface developer, and thereafter developing the picture area only as by roller application of an internal developer. The two emulsions may have different speeds to provide greater latitude in exposure. Thus, if the Type I emulsion is the faster, and if under-exposure is found after surface-image development, immersion in an internal developer will further develop the Type I emulsion ; or, if the Type II emulsion is the faster, and if over-exposure is found after surface - image development, the developed image can be removed as in a bichromate bleaching bath and a satisfactory image then developed in the Type I emulsion with an internal developer. Specification 541,510 also is referred to.

Abstract: 169,950. Trent Process Corporation, (Assignees of Trent, W. E.). Oct. 4, 1920, [Convention date]. Dry processes of extracting metals.- In a process for reducing iron and other ores, the ore from a receptacle A is pulverized, either by a wet or a dry process, and fed to a mixer D along with similarly treated coal from a receptacle A<1>, the mixture passing to a lowtemperature chamber E where it is heated to 300-400‹ C. to remove the oil from the coal and reduce partially the iron &c. in the ore. The gases pass through a pipe to a combustion chamber N, the heavier byproducts (oil &c.) passing to a condenser F and the ore &c. to a magnetic or other separator G. The carbonized dust &c. is led by a pipe G' to a mixer 1 where it is mixed with water, the product passing to an amalgamator J where it is intimately mixed with the by-products passing by a pipe F<1> from the condenser F. The amalgam of coal and oil pass into a low temperature retort K, and the carbonized particles are introduced by a pipe K<1> into a mixer H along with the ore &c. from the separator G, passing then into a combustion chamber N having a reducing- flame therein. The molten metal passes on to a hearth O along with the gases, freed from oil &c., in the condenser M, from the retort K and is removed therefrom by a pipe for further treatment if desired. The oil from the condenser M is returned to the amalgamator J. If desired, only a part of the coal may be introduced into the mixer D, the rest being delivered to the mixer I. The waste gases from the chambers E, N or the retort K may be used for other purposes.
