Title: Improvements in and relating to electric discharge devices
IPC: H01J13/48
Filed: 1933-02-10
Abstract: 405,460. Discharge apparatus. INTERNATIONAL GENERAL ELECTRIC Co., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Electricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin.) Feb. 10, 1933, No. 4136. Convention date, Feb. 10, 1932. [Class 39 (i).] The ignition device of a discharge vessel such as a metallic-vapour rectifier is protected by means of a thermal switch, which is heated directly, or through a transformer, by the current operating the ignition device to open the ignition circuit after a limited number of operations thereof. A cathode 4 and an ignition electrode 5 are connected to a current supply 6 through a resistance 7 and a switch 9 adapted to be operated by the load current. The electrode 5 is repeatedly brought into contact with the cathode by means of the solenoid 10 until, if the discharge has not started, a bimetallic switch 11 operates to open the ignition circuit. The switch is locked by the latch 12 but may be released by the coil 13. The connection of several vessels in parallel may be prevented in the event of the non- ignition of one vessel.

Title: Differential-pressure cushioning apparatus for colliery jigging conveyors, shaking screens and the like
IPC: B65G27/14
Filed: 1927-02-16
Abstract: 288,772. Norton, G. Feb. 16, 1927. No-'Patent granted (Sealing fee not paid). Pneumatic springs.-A pneumatic cushioning- apparatus for reciprocating apparatus is adapted to exert a greater force in one direction than in the other when used, for instance, with inclined jigging-conveyers or with shaking-screens. This effect is obtained by charging one end, before the compression stroke starts, with air obtained from the other end at a certain part of its compression stroke. In the apparatus shown in Fig. 1 the weight of the inclined apparatus is balanced by the greater average pressure at the lower end of the cylinder. The piston starts its upward movement with port C uncovered so that air at atmospheric pressure is compressed into the end of the cylinder and into the port chamber D, E. When the piston has travelled upwards sufficiently to uncover the port D, the air trapped in the chamber D, E is transferred to the lower end of the cylinder so that the piston on its downward stroke compresses air which is initially at a pressure above atmospheric. A differential ram could be used in place of a piston. Compressed air admitted through a reducing valve could be employed to supplement the charging effect at the lower end.

Class 82. - In a drum-type apparatus for pickling, cleaning, phosphating and dip coating, pockets are formed on the drum periphery by a series of rollers or other elements rotatable about axes parallel to the drum axis and spaced around the drum inwardly of the periphery, and a discharge member such as a rod which extends parallel to the drum axis at the periphery and is adjacent the trailing edge of each pocket is positioned to engage a component in a pocket when said pocket has passed to the highest point of a curved surface associated with the drum so as to encompass part of the lower periphery of the drum, said component then rolling outwards and being discharged. As shown in Fig. 3, the drum is formed of two end plates 7 and two intermediate plates 9 mounted on a hub 8 with ten discharge rods 10 spaced equiangularly around the periphery and secured to the end plates. At each of these ten positions radially inwardly of the rods is mounted a spindle 15 carrying rotatable rollers 16, two rollers being located between each of the plates and spacers 17 maintaining the spacing between the rollers. Rods 18 carrying hollow sleeves 19 are mounted intermediate these ten positions and radially inwardly of the rollers 16. The outer edge 20 of the intermediate plates 9 is scalloped so that the periphery of each roller 16 projects beyond the edge. A drum is mounted in each of a series of pickling or washing tanks 1, 2, 3 (Fig. 1) and a curved plate 21 extends the length of the tanks and conforms to the shape of the immersed outer surface of the drums. Cylindrical components are fed into the drum 4 and on rotation of the drum the components are passed through the liquid and discharged into the next drum 5 and then into drum 6. Alternatively non-cylindrical components are packed in perforated cylindrical containers which are then fed to the drum apparatus.

Filed: 1938-02-18
Abstract: 511,509. Cable end sleeves. SOLUTION TRUST, Ltd. Feb. 18, 1938, Nos. 5109 and 5110. Convention dates, Feb. 18, 1937, and Feb. 12, 1938. Addition to 471,536. [Class 36] In an end fitting of the kind described in the parent Specification for a cable having one or more conductors insulated from a surrounding metal sheath by pulverulent refractory material such as steatite, a deformable insulating body or mass is maintained in compression in the end of the sheath or in a sleeve tightly secured thereto by an axially movable clamping element so as to be pressed tightly into direct contact with the cable insulation and to maintain a fluid-tight joint at the cable end preventing ingress of moisture to the cable insulation. In the construction shown in Fig. 1, a body 3 of rubber, incombustible wax, or asbestos contained within a sleeve 5 secured to the end of the cable sheath 10 is tightly pressed against the end of the cable insulation 2 by an insulating thrust member 4 which is drawn into the end of the sleeve by a nut 6 screwing on the sleeve. The conductor 1 passes from the member 4 through a packing gland 8. Fig. 2 shows an elastic insulating body 5<1> tightly pressed in the splayed out end of the cable sheath 2<1> against the cable insulation 3<1> by an insulating thrust member 4<1> forced against the body 51 by a nut 6<1> into which is screwed a sleeve 71 having a conical surface for engagement with the outer surface of the splayed out end of the cable sheath. In a modified construction, Fig. 8, the splayed out end of the sheath 2<1> is gripped between a conical insulating ring 14 and a conical portion of a sleeve 16<1>, the two being moved into clamping engagement by an externally screwthreaded and internally coned sleeve 18 which screws into the sleeve 16<1>, thereby forcing an externally coned, insulating thrust member 16 against .the ring 14 and also compressing incombustible wax which fills the spaces 5<11>. When the cable contains a plurality of conductors the thrust members may be of the form described in Specification 473,307.

Title: New anthraquinone vat dyestuffs and process for their manufacture
IPC: C09B1/42
Filed: 1962-02-12
Abstract: The invention comprises anthraquinone vat dyes which contain at least one oxdiazole ring and at least one acylamino group, especially an aroylamino group, which is substituted by a sulphohalide group, and particularly dyes of the formula <FORM:0954410/C3/1> where X is a direct bond or an arylene bridge, n is 1 or 2, A is an anthraquinone residue, such as an aminoanthraquinonyl or an anthraquinoneacridone residue, and Y is an aroylamino group containing a sulphohalide group.  The dyes are made by acylating aminoanthraquinones containing at least one oxdiazole ring with a carboxylic acid halide containing a sulphohalide group, by sulphochlorinating an anthraquinone vat dye containing an acylamino group and either an oxdiazole ring or a group of the formula -CO-NH-NH-CO- and when the latter group is present simultaneously forming the oxdiazole ring, by chlorinating the appropriate vat dye sulphonic acid or oxidatively chlorinating the appropriate isothiouronium compound. Aminoanthraquinones which may be acylated are compounds of the above general formula where Y is hydrogen, reaction products of diaminoanthraquinones with reactive derivatives of dicarboxylic acids containing oxdiazole rings and phenyl- or aminophenyl - oxdiazolylanthraquinones containing a -amino groups.  The acylating agents mentioned are derived from the sulphonic acid carboxylic acids of thiophene, naphthalene and substituted and unsubstituted benzene, and from sulphoacetic and sulphochloracetic acids. Examples are given.  The dyes vat-dye and print textiles of natural or regenerated cellulose and the dyeings may be coated with polyvinyl chloride.
