Title: Pressure vessel
IPC: F15B1/10
Filed: 1956-03-02
Abstract: 826,571. Hydraulic accumulators; pressurerelieving devices for fluids. MERCIER, J. March 2, 1956 [March 2, 1955], No. 6670/56. Classes 69 (2) and 135. An hydraulic accumulator comprises an outer casing 11, a deformable resilient partition 15, and a perforated core member 14, the core enclosing a cavity the volume of which is less than the volume of a body of revolution having the same external dimensions as the core. The core, in cross-section, may be shaped as shown in Figs. 2 or 4. Alternatively, the core may be elliptical and comprise a close coiled spring. To prevent the partition 15 distending through the perforations of the core member when a pressure difference exists in the accumulator, inlet and outlet connections at the top and bottom of the accumulator may be joined by piping containing one-way valves so that excess liquid can pass to the air containing portion and excess air can pass to the liquid-containing portion. The accumulator may be designed to take up surges in a pipe and for this purpose is of tubular form. In a further embodiment, Fig. 10, the accumulator 101 comprises a perforated core 111, a partition 115, and a rigid perforated sleeve 116, these members being mounted in end plugs 104, 108. Air is supplied through a pipe 103 and a pump 148 supplies liquid from a tank 149 to a member 121 connected to the bottom of the accumulator. Oneway valves 154, 155 are provided to allow the liquid or the gas to pass from one side to the other of the partition to relieve excess pressure and prevent distension of the partition 115. A valve 131 is provided in the member 121 and is acted on by a spring 135 and by the pump pressure via a pipe 142. When a valve 138 is opened, liquid is drawn from the accumulator until a predetermined pressure is reached when the spring 135 closes the valve. In a modification, the left-hand end of the valve 131 is connected by a pipe to the air supply pipe 103 and a second spring is provided in the right-hand end of the valve.

IPC: G21C19/02
Filed: 1959-02-27
Abstract: 923,442. Servicing reactors. ROLLS-ROYCE Ltd. Jan. 4, 1960 [Feb. 27, 1959], No. 7033/59. Class 39 (4). [Also in Group XXX] A grab for handling fuel elements comprises a pair of chains 18 (Fig. 2) formed with abutments 18d so that they can bend in one direction only, the chains being fed into a side-by-side position in which each chain opposes bending of the other chain so that together they form a rigid probe. In the form shown, the chains have rollers 22 passing over driven sprockets 17 by which they can be retracted into housings 19 (Fig. 1). The links of the chains are of U-section, the ends of the webs 18c (Fig. 4) forming the abutments 18d. Channel rollers 23 engage guides 24, 15. The chains terminate in a castellated sleeve 20d located inside a sleeve 20k which can be rotated so that dogs 20m hold portions of an engaged fuel element captive in the slots between the castellations 20d. Rotation of the sleeve 20k is effected by independent movement of one of the chains 18 which carries a spindle 20g engaging a helical slot 20j in the sleeve 20k. The drives to the sprockets 17 carrying the chains may be from a front wheel through a differential gear which includes a brake applied when only one of the chains is to be moved. The grab is employed to withdraw fuel elements from a reactor 10 into a removable coffin 13 formed with a slide valve 15 and a rotary valve 14. The aperture 11 may be formed in a member which is adjustable to enable it to be alinged with fuel element bores in the reactor.

IPC: C01B17/60
Filed: 1967-02-14
Abstract: 1,143,847. Recovering sulphur dioxide. PROGIL. 14 Feb., 1967 [14 Feb., 1966], No. 7061/67. Heading C1A. Sulphur dioxide is recovered from a mixture thereof with one or more gases, particularly the gaseous effluent from the manufacture of sulphuric acid by the "contact" process, by reacting the mixture with an aqueous solution comprising one or more alkali metal phosphates. Preferably the aqueous solution contains di- and trialkali metal phosphates and comprises the mother liquor remaining after crystallization of alkali metal phosphate from the reaction mass resulting from the reaction of phosphoric acid with at least one alkali metal hydroxide or carbonate: it may also contain wash solutions resulting from washing the crystallized phosphate, and also at least one alkali metal carbonate or hydroxide. The solution so obtained, comprising alkali metal sulphite and bisulphite, may be converted into sulphate by treatment with oxygen, conveniently in the form of air, sulphur dioxide being released in the case of bisulphite. A bisulphite solution may be treated with sulphuric acid to produce sulphur dioxide, which may be removed by passing air through the solution at a rate such that the effluent gases may be used in the "contact" process for the manufacture of sulphuric acid. The residual alkali metal sulphate solution may be used in conjunction with sulphuric acid for the manufacture of phosphoric acid by reaction with naturally occuring phosphate ore.

Title: Improvements in or relating to Twin Lens Cameras with Interchangeable Objectives.
IPC: G03B17/14
Filed: 1968-02-13
Abstract: 1,193,535. Parallax indicators. KONICA CAMERA CORP. Feb. 13, 1968 [Feb. 17, 1967; Nov. 10, 1967], No. 7155/68. Heading G2A. A twin lens reflex camera having inter-changeable lenses has means for indicating the amount of parallax, which means is visible in the view-finder, and which automatically adjusts itself to the focal length of the particular lens attached. As shown, a viewing lens 2 and taking lens 2<SP>1</SP> are carried on a board 1 mounted on a plate 3. The system can be adjusted axially for focusing by a rack and pinion arrangement 4, 5. A pin 9 is secured to the board 1, and against the pin rests one end 7 of a cam 6 which is attached to the plate 3 by a pivot 8. A lever 10 is pivoted to the camera body at 12, and spring-urged so that a pin 11 at its lower end bears against a bar portion of cam 6, so holding the cam firmly against pin 9. The slotted upper end of lever 10 slidably engages a needle 14 which is visible in the viewing screen 13 and indicates the amount of parallax. As the lenses are moved axially for focusing adjustment, cam 6 causes corresponding movement of pin 11 and lever 10, and hence of indicator needle 14. When board 1 is replaced by another board carrying lenses 2, 2<SP>1</SP> of a different focal length, the pin 9 has a correspondingly different length, so giving cam 6 a different inclination. Fig. 3 (not shown) is a modification in which the parallax indicator is a frame sliding parallel to the plane of the viewing screen.

Title: A method for the preparation of alkali metal salts of lactams
IPC: C08G69/20
Filed: 1963-02-22
Abstract: Alkali metal salts of lactams containing at least 4 carbon atoms in the ring or mixtures of such lactam salts with lactams are prepared by causing or allowing an alkali metal hydroxide to react with an excess of a molten lactam containing at least 4 carbon atoms in the ring, removing the water formed during the reaction from the molten reaction mixture, and thereafter pouring the molten reaction mixture into a dry organic liquid, which is inert to lactams and alkali metal salts of lactams, in which alkali metal salts of lactams are insoluble and which has a boiling point of at least 30 DEG C. and a melting point of not more than 15 DEG C., and separating the precipitate so formed. Several suitable liquids are specified and the precipitate formed is preferably washed with dry ether.  The reaction is preferably conducted at a temperature within the range 95 DEG C. to 160 DEG C. and at a pressure corresponding to the vapour pressure of the lactam at the temperature employed. Examples are given.  The salts are used as catalysts in the alkaline polymerization of lactams (see Division C3).ALSO:Alkali metal salts of lactams containing at least 4 carbon atoms in the ring (see Division C2) are used as catalysts for the alkaline polymerization of lactams.  Examples describe the polymerization of (4) a mixture of e -caprolactam and sodium caprolactam in a mould to which is added a mixture of caprolactam and acetyl caprolactam; (5) a mixture of dodecanolactam and sodium caprolactam to which, when molten, is added a molten mixture of dodecanolactam and N-aryl caprolactam.
