Title: Improvements in multi-way valves for liquids, specially applicable for use with water softening apparatus
IPC: C02F1/42
Filed: 1938-07-29
Abstract: 516,906. Multi-way valves. MARSHALL, C. G. July 29, 1938, Nos. 22556 and 26878. [Class 135] A valve, particularly for water-softeners, comprises a casing 2, Figs. 2 and 3, provided with five branches HI .. HO, and a conical plug 4 or other rotary valve-member such as a disc which is formed with two cross-passages 13, 14 and a branch 15 and can be set in five different positions to determine five different paths of flow. Provision may also be made for setting the plug in a sixth position in which all the ports are cut off. As applied to a water-softener, the ports HO and SI are connected to the inlet and outlet thereof. Normally the flow from the inlet HI is through the ports HO, SI, and soft water is delivered through the port SO. For backflushing. the flow is through the ports HI, SI, HO, and the drain port D. For regeneration, the flow is directed through the ports SI, D, then through the ports HI, HO, SI, D, next all the ports are cut-off, and then is again directed through the ports HI, SI, HO, D. If hard water is required, the flow is directed from the port HI to the port SO. The spindle 6 of the plug passes through a gland 7 and is provided with a spring-washer 17 for holding the plug in engagement with the casing. A pivoted, spring- pressed handle 5 on the spindle is set with reference to marks on a cover 3, and co-operates with pairs of retaining-lugs 9. When a discvalve is employed, the passages open into ports in the flat face of a disc which co-operates with a flat face in a ported casing.

Title: Improvements in or relating to methods of and devices for forming supporting wires for filaments of incandescent lamps and the like
IPC: H01K1/18
Filed: 1931-08-11
Abstract: 381,655. Making electric lamps. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D. Emmasingel, Eindhoven, Holland. Aug. 11, 1931, No. 22675. Convention date, Aug. 13, 1930. [Classes 83 (ii) and 83 (iv).] Angular bending; dies.-The mounting- wires for the filaments of an electric incandescent lamp are so arranged that the filament is solely supported intermediate its ends by means of eyelets formed by a single helical turn at the ends of a series of mounting-wires secured substantially in the same horizontal plane at the top of a supporting stem, the forms of the mounting-wires b, Fig. 3, being such that in any position of the lamp the filament a<1> is supported by one point only of each eyelet d<1> and has a tendency to bear on a point p<1> at the side of the eyelet adjacent to the support for the mounting-wires. As shown in Fig. 3 the result is obtained by giving the mounting- wires each a substantially right-angle bend. An apparatus for bending the end portions of the mounting-wires at right-angles to the main portions thereof comprises a receiving- head 1, Fig. 5, with a central aperture 2<B> to receive the central glass stem, and an upper portion 2 formed with an upwardly flanged edge 2<A> across which the straight wires radiating from the stem are laid. Mounted above the head 1 is a vertically movable plunger 6 which is arranged within a cylindrical casing 7 provided at its lower end with three jaws 3 mounted thereon on pivots 8 and held normally towards one another by an encircling spring 26. The casing 7 is slidably mounted within a guide 24, its movement being restrained by laterally disposed spring-pressed plungers 18 bearing upon its periphery. During the downward movement of the plunger 6 a collar 9 thereon engages an internal shoulder 25 on the casing 7, thereby depressing the latter and forcing the jaws 3 on to the filamentmounting wires, which are bent upwardly by the flanged edge 2<A> of the head 2. The lower end 16 of the plunger 6 is shaped conically so that when the plunger begins to rise the jaws 3 can be pulled inwardly away from the bends in the wires by the spring 26, the member 7 meanwhile being held stationary by the plungers 18 until a collar 10 on the plunger 6 strikes a cap 11 at the upper end of the casing 7, causing the latter to be raised to its highest position.

Title: Improvements in and relating to furnace grates
IPC: F23H9/00
Filed: 1924-09-27
Abstract: 244,845. Marks, E. C. R., (Soc. Anon. des Brevets Titan). Sept. 27, 1924. Grates.-In furnace grates, of the kind having a fixed part 1 and an eccentrically pivoted dumping-portion 6, the pivotal shaft 7 is arranged below the level of the grate 6 so that only a small movement of the latter is necessary in order to cause its centre of gravity to shift from one to the other side of the shaft 7. A rod 8, secured in the fixed part of the grate and passing through a curved slot 9 in the grate 6, serves as a guide for the latter and also acts as a stop to limit the movement in either direction. The rod 8 and/or the shaft 7 may be mounted in the walls of the ash-pan and the greater weight of one arm of the grate 6 may be ensured by the provision of a fixed or adjustable weight. The dumping-grate 6 may be U-shaped in plan or may be arranged so that the two arms are staggered longitudinally. In another construction two dumping-grates 6 are provided, one on each side of a fixed part of the grate. In the modification shown in Fig. 6, the grates 6 are arc-shaped, the inner ends of the fixed bars 1 being correspondingly curved as shown at 1<1>. Specification 134,533 is referred to.

Title: Improvements in and relating to the manufacture of printing plates
IPC: B41D3/00
Filed: 1925-09-14
Abstract: 262,852. Marks, E. C. R., (Wood Newspaper Machinery Corporation). Sept. 14, 1925. Stereotype, casting.-In a mould for casting stereotype plates without a riser, an ejecting- device is provided for separating the casting from the riser or metal supply in such a way that some of the displaced metal tends to flow into the mould to compensate for shrinkage of the plate during cooling, the ejecting-device being arranged to move in a direction radial or perpendicular to the mould core, or transverse to the cast plate. In addition, a gate for controlling the supply of metal to the mould is provided, the ejecting- device being adapted to eject the metal between the edge of the plate proper and the gate. The mould is formed by a semicylindrical back 10 capable of vertical movement for stripping the matrix, and a rotatable cylindrical core 11 having two casting-surfaces. The matrix 14 is held on the back 10 by clips 13. Molten metal is supplied to a hopper 15 provided with a heating- device and mounted directly above the mould. The metal enters the mould through an aperture 16 in the bottom of the wall 17 of the hopper, the wall being provided with a part fitting closely against the core 11 to prevent escape of the metal. When a plate has been cast and before it has finally solidified, a plunger 24, of a width equal to the distance between the lower edge of the aperture 16 and the lower edge of the matrixclip 13, is moved into the mould cavity to eject the metal above the type edge of the plate. As shown, the plunger 24 is mounted in the core 11 and is operated by a slide 25. The slide and plunger are connected together by a tongue and groove which are out at an angle to the face of the core so that operation of the slide moves the plunger into or out of the mould cavity. Alternatively, the plunger 24 may be pushed into the cavity from one end. After the plunger has closed the cavity, a gate 20, operated in timed relation with the plunger, is moved into the aperture 16 to cut off the supply of metal and to force any metal in the aperture back into the hopper 15. Grooves 23 in the upper surface of the gate facilitate the return of metal to the hopper.

Title: Improvements relating to fire-extinguishing apparatus
Inventor: HENSHAW THOMAS ANTHONY
IPC: A62C13/00
Filed: 1955-08-10
Abstract: 807.919. Fire extinguishing apparatus. PYRENE CO. Ltd. Aug. 10, 1956 [Aug. 10, 1955], No. 23071/55. Class 47 An assembly of a gas bottle and piercer or valve mechanism is carried, in a readily removable manner, outside the wall of the container for the fire extinguishing medium in a holder, the assembly and the holder each having a passage, these passages registering with one another in a gas-tight relationship when the assembly is positioned in the holder, to provide a connection from the gas bottle to the interior of the container. In Fig. 1 a gas bottle holder 11 closes the neck 7 of the container 1 and forms part of the wall of the container. The gas bottle 13 is screwed into a piston-like flange 26 which forms part of a piercer mechanism 14, the flange having an inner space 28 and a radial passage 27 with which the gas bottle communicates. The flange 26 is a sliding fit within a cylindrical part of the holder so that the assembly of the gas bottle and piercer mechanism is readily removable from the holder and is circumferentially located therein by a key 34 and keyway 35 so that the passage 27 registers with a passage 24 in the holder opening into the container 1. An O-ring 21 surrounding the passage 24 ensures gas tight communication between the passages 24, 27. When the apparatus is out of use the container 1 can "breathe" because the piercer plunger 38 is held slightly depressed by the normally closed cap 44, thereby holding a sealing ring 31 away from a flange 37. When the apparatus is operated the cap 24 has to be opened thereby allowing the plunger 38 to rise under the action of the spring 42 so that the seal 31 engages the flange 37 preventing escape of gas after the seal 32 of the bottle 13 has been broken by depressing the plunger 38. The gas passes into the container 1 through the space 28, and passages 27, 24 and expels fire extinguishing liquid through a dip tube 3, discharge hose 5 and nozzle 6. In a modification, Fig. 3 (not shown) the O- ring 21 is replaced by two O-rings around the circumference of the flange 26 and the passages are modified so that the flange 26 need not be circumferentially located in the holder 11. In Fig. 4 and also in Fig. 6 (not shown) the assembly of the gas bottle and piercer mechanism is mounted at the side of the container of a powder fire extinguishing medium, the holder being formed by a bracket 56 recessed to receive a lug 47 on the assembly and carrying an O-ring 51 to form a gas tight connection between passages 48, 49 in the bracket 56 and lug 47 providing the communication between the gas bottle and the container. Specification 807,920 is referred to.

Title: Process for the separation of mixtures of 4- and 5-nitroanthranilic acids and their salts
Inventor: BAXTER RICHARD ALLEN
Filed: 1953-08-21
Abstract: 4-Nitroanthranilic acid is isolated as such or in the form of a derivative by treating a mixture of 4- and 5-nitroanthranilic acids or their salts with an acylating agent, whereby preferential acylation of the 4-nitroanthranilic acid or its salt takes place to give a 2-acylamino-4-nitrobenzoic acid or its salt, which is isolated as such or in the form of 4-nitroanthranilic acid or another of its derivatives.  Specified acylating agents are acetic and propionic anhydrides and acetyl chloride.  Usually a mixture of the sodium or potassium salts of the 4-and 5-nitroanthranilic acids is used.  The acylated acid, i.e. 2-acylamino-4-nitrobenzoic acid can be separated from the unchanged 5-nitroanthranilic acid by fractional crystallization or by adjusting the pH of a solution thereof until the 5-nitroanthranilic acid, being the weaker acid, is precipitated (e.g. at pH 4.5).  The 2-acylamino-4-nitrobenzoic acid may be precipitated from the resultant solution with mineral acid and hydrolysed (preferably with acids) to give 4-nitroanthranilic acid. The mixture of 2-acylamino-4-nitrobenzoic acid and 5-nitroanthranilic acid, or the salts thereof may be reacted with other reagents (for example, free carboxy groups can be esterified) before the separation.  In Examples: (1) a mixture of 4-and 5-nitroanthranilic acids obtained from 4-nitrophthalimide by treatment with sodium hypochlorite, is dissolved in sodium hydroxide, acetylated with acetic anhydride to give a reaction mixture of pH 4.5, the residue of 5-nitroanthranilic acid being filtered off and the filtrate being acidified to precipitate 2-acetylamino-4-nitrobenzoic acid which is hydrolysed with hydrochloric acid to 4-nitroanthranilic acid; (2) the mixture of sodium salts of 4- and 5-nitroanthranilic acids obtained by treating 4-nitrophthalimide with alkaline sodium hypochlorite is treated as in (1).
