Title: HALOGEN-CONTAINING PHOSPHONIC ACID DERIVATIVES AND THEIR CONVERSION TO (Cis-1,2-EPOXYPROPYL) PHOSPHONIC ACID AND DERIVATIVES THEREOF
Inventor: GLAMKOWSKI EDWARD JOSEPH
IPC: C07F9/655
Filed: 1969-05-12
Abstract: 1,244,557. Phosphonic acid derivatives. MERCK & CO. Inc. 12 May, 1969 [15 May, 1968], No. 23966/69. Heading C2C. (Cis - 1,2 - epoxypropyl)phosphonic acid or a salt or ester thereof is obtained by treating a [(1 - haloethoxy)halomethyl] phosphonic acid or salt or ester thereof with a reagent that releases iodide ions in solution, e.g. KI, and/or with a coupling agent comprising one or more metals of Groups I A , IB, II A  or IIB of the Periodic Table capable of effecting epoxide-type ring closure. Specified 1-haloethoxyhalomethyl phosphonic compounds are novel compounds of the formula where X and X<SP>1</SP> are halogen and R is hydrogen, alkyl, C 2 -C 5  alkenyl, aryl or aralkyl or an alkali metal, alkaline earth metal, magnesium or amine cation. The latter may be obtained by reacting a corresponding compound with acetaldehyde in the presence of a gaseous hydrogen halide and then subjecting the product to free radical halogenation, e.g. by treating with a tert.butyl hypohalite and with an azo bisisobutyronitrile initiator. Specified coupling agents for use in the main process are Li, Na and Mg and Zn-Cu couples. When an ionizable metal such as Li, Na or Mg is used the product may be the corresponding metal salt of the phosphonic acid and this salt may be converted to the free acid by passing an aqueous solution thereof through a cation exchange column on the hydrogen cycle. When R is alkyl, C 2 -C 5  alkenyl, aryl, aralkyl or the cation derived from Mg or an alkali metal or alkaline earth metal, ring closure is preferably effected in the presence of crystalline iodine and/or either Li, Na, Mg or Zn-Cu couple and when R is other than hydrogen the salt or ester product can be converted to the free acid by various defined methods and the free acid can be converted to a salt by treatment with a suitable base. The main process is generally carried out in a solvent e.g. an ether and if desired may be conducted in an inert atmosphere e.g. of nitrogen or argon. The product may be obtained either as a racemic mixture or as an optically active isomer and the () and (-) acid and salts thereof have antimicrobial properties. Diethyl hydrozymethylphosphonate is obtained by reacting diethyl phosphite with a slight molar excess of formaldehyde at 5 C. and then distilling the reaction mixture.

Title: Improvements in or relating to roll carriers for photographic strip film
IPC: G03B21/32
Filed: 1935-08-29
Abstract: 461,993. Kinematographic and rollfilm spools. KODAK, Ltd. Aug. 29, 1935, No. 24130. Convention date, Oct. 25, 1934. [Classes 97 (i) and 98 (i)] A roll carrier for strip film comprises at least one aperture in the hub upon which the film is wound and a latch or trigger which is automatically acted upon by the hub support or a part of the same to obstruct the said aperture and prevent re-exposure of the film. The reel comprises a hub, two flanges 2, 3 and a disc 5, the flange 3 having a keyhole aperture 7 which co-operates with the driving member 8 on the take-up spindle 6. A pivoted shutter 10 is locked against the action of spring 11 by a trigger 9. When the reel is mounted on the take-up spindle 6 the latter engages the trigger 9, and the shutter is turned across the aperture 12 and prevents the reel from being mounted in a spindle for supply. The aperture 21 may be of different shape from the aperture 7 and the supply spindle of the camera is provided with projections for co-operation with the aperture 12. In Fig. 6, the pivoted shutter is held by the nose 22 of a pawl 20 which is liberated by a push-button 21 when the reel is mounted on the supply spindle. The push.button is actuated by a portion of the camera and the shutter swung into engagement with the spindle. When the film has been unwound and the reel is withdrawn the shutter swings across the opening so that the reel cannot be replaced on the supply spindle, e.g after use on the take-up spindle. When the kinematograph magazine is of the reversible type, i.e. for taking two rows of images, each aperture may be provided with an obstructing device as described. In a modification (not shown) a sliding shutter plate is restrained by catches operated by a push button, the latter preventing full movement of the shutter plate. When the magazine is removed after exposure the push button moves back under spring action to liberate a catch and allow the shutter plate to slide into the obstructing position.

Filed: 1926-09-30
Abstract: 264,763. Siebenmann, D. Sept. 30, 1926. Fire-extinguishing by gases or solutions; sprinkling-apparatus. - The valve-lever 3 of a bottle or pipe 2 for extinguishing gas or liquid is opened by the pull of a falling weight 9 when the latter is released by hand or electro-magnetically. The weight is held raised by a cord 5 con. nected to the lever 3 by a cord 4 and wound on a winding drum 10. The latter is held from rotation by pins 19 on a sleeve 16. The sleeve is slidable, to release the drum 10, by means of a hand lever 18, or automatically by means of an electro-magnet 22 which is energized by heat acting on a thermal device 26 operating through a cross-coil 25 and relay 24. The circuit can also be closed by a hand-switch 23. If the place to be protected has an aperture 29, the falling weight may also close a flap or valve 30. A pointer 32 on the cord indicates the position of the weight 9. In a modification, the movement of the sleeve 16 is arranged to move, through a lever, a contact device which operates to interrupt the electro-magnet circuit as soon as the core of the latter has completed its working stroke, and to close a second circuit which may, for example, initiate the weakening of the field of an electric generator, or actuate any other protective device for such machinery. The contact device is so linked with the sleeve as to be quickacting. The electro-magnet may be in circuit with several different hand or thermal switch devices.

Abstract: 493,528. Treating rice. HUZENLAUB, E. G., and ROGERS, J. H. April 8, 1937, No. 24360/38. Divided out of 494,085. [Class 58] Paddy or dehusked rice is soaked by steeping it in water and subsequently dried, the soaking process being accelerated by subjecting the steeping water to a pressure above the pressure of the atmosphere and above the vapour pressure of the steeping water. The paddy or dehusked rice is fed into a digester 1 the cap 2 then being closed; a partial vacuum is produced in the digester and water between 60 and 90‹ C. added through a cock 23 and a hollow trunnion 6a. The digester is then rotated in its bearings 7 and air or gas admitted through a valve 26 so that the pressure rises to 100 lb. per square inch ; the digester may be heated by a steaming jacket. After about one hour the pressure is released, excess water drained away and steam admitted to raise the pressure to 181b. for three to four minutes and then suddenly blown off. A steam treatment with blowing off may take place before the remainder of the treatment. The digester may be discharged on a conveyer leading to a drying machine or sun floor or the digester may be subjected to vacuum to lower the water content. The steeping water may be comparatively cold, e.g. between 16 and 30‹ C.

Filed: 1926-10-04
Abstract: 265,492. Worsley Mesnes Ironworks, Ltd., and Bedford, W. H. Oct. 4. 1926. No Patent granted (Sealing fee not paid). Cataracts.-The rate of movement of a piston in a cylinder may be limited by adjustable valves, or it may be locked hydraulically, the looking or the release being controlled by a piston valve. The piston c may be connected to an auxiliary mine cage which is lowered within limits by the weight of loaded trams or is raised when unloaded by balance weights. Above the cylinder and valves is arranged a liquid reservoir d with a protected air vent f, the level of the liquid being such that all the valves and pipes are submerged or filled. When the hand-controlled piston valve m, n is in the central position shown, liquid cannot escape from either end of the cylinder and the piston is therefore locked. When the valve is adjusted downwardly, the piston is free to move downwards, its rate of movement being regulated by the adjustable valve 6. Liquid then flows from the bottom of the cylinder through pipe p, valve 6, passage g, and passage h to the reservoir d, while liquid enters the upper part of the cylinders through the non-return lift valve t. Similarly when the piston value m, n is adjusted upwardly, the piston c is free to move upward, its rate of movement being regulated by the adjustable valve 5. Liquid then flows from the top of the cylinder to the tank d by the passage p, valve 5, pipe q, passage j, and passage h, while liquid enters the lower part of the cylinder from the tank d through the one-way valve u, passage s and pipe p. Air may be withdrawn from the top of the cylinder through the plug v and from below the piston c by a vent 2, passage 1 and valve 3.
