Title: Method of, and apparatus for making galvanic anodes for use in the cathodic protection of metallic structures
IPC: C23F13/02
Filed: 1955-03-16
Abstract: 777,815. Continuous-casting machines; casting composite articles. DOW CHEMICAL CO. March 16, 1955 [May 19, 1954], No. 7717/55. Class 83 (1). Galvanic-anodes having a core disposed within the consumable part thereof, are made by introducing molten-metal into one end of a continuous-casting mould, feeding a continuous length of metal core into the mould and continuously withdrawing solid - metal which is bonded to the core from the other end of the mould. The melt, magnesium, aluminium or alloys thereof, is fed through pipes 26, 28 directed so that the melt impinges on and tends to clean the steel-core 30, which is fed to the mould by rollers 36. The surface of the melt may be protected by directing SO 2  gas thereon. In a modification, the molten-metal is directed into the mould from one pipe dipping below the surface of the melt in the mould, and in a further modification the melt is directed from a pipe on to the core.above the surface of the melt. The core may be galvanized or aluminized. Specification 777,816, [Group XVIII], is referred to.

Title: Improvements in or relating to operating mechanism for electrical circuit breakers
IPC: H01H3/30
Filed: 1956-03-16
Abstract: 856,874. Actuation of switches; automatic circuit-breakers. YORKSHIRE SWITCHGEAR & ENGINEERING CO. Ltd., and CATON, G. March 13, 1957 [March 16, 1956], No. 8321/56. Class 38 (5). A circuit-breaker operating mechanism comprises an operating element 26 with a fixed pivot 24, a spring unit 36 pivoted at one end 42 to the element 26, and a link 22 for linking the other end of the spring unit 36 to the circuitbreaker operating linkage 3, the link 22 being mounted on the pivot 24 so as to be capable of liner movement. When the element 26 is turned anticlockwise to stress the spring unit 36, a small initial downward movement of the link 22 occurs until a stop pin 34 engages the end of a catch 31, the movement taking up any play between the parts of the mechanism. Thereafter the link is latched as the movement of the element 26 continues to stress the spring unit. When the spring unit is fully stressed, a projection 29 on the element 26 moves the catch 31 so as to release the stop pin 34. The link 22 is now moved downwardly by the spring unit 36 to actuate the linkage 3. The element 26 may be operated by a handle 28 or by power means. The operating element 26 and the spring unit may be readily detachable, Fig. 3 (not shown). For maintenance purposes the spring may be held in its unstressed state by reversing a cover-plate 44.

A grinding or polishing body or band comprises a carrier having an applied layer of steel wool secured to the carrier by an adhesive, the steel wool having a plaited, woven, braided or like structure formed of interwoven steel wool fibres. The carrier may be a knitted fabric, a rubber band or be cut from a sheet of resilient artificial material. The adhesive may be such as to wet the steel wool fibres so as to encase the base of the fibres, and to be elastic when dry, cold or otherwise set. The steel wool plaits &c. may run non-parallel to the longitudinal direction of the carrier, as shown in Figs. 3-7. The body or band may be reinforced at its edges, as by a member secured along the carrier edge, Figs. 8 and 9, or by doubling over the carrier at its edge, Fig. 10. A band polishing machine having a band as described above passing round rollers may be provided in the region of the direction-changing rollers with belts engaging the steel wool layer from the outside so as to prevent loosening of the layer due to centrifugal force as the band passes round a roller. The external belt may extend over the entire width of the band or may comprise narrow belts side by side. The belts may be of open-work form to permit the removal of abraded particles or dust by the centrifugal force.

Abstract: 593,409. Moulding concrete flags &c. HOPPERTON, J. E. May 6, 1944, No. 8637. [Class 87 (ii)] A machine for manufacturing pressed concrete flags of different sizes without the need for adjusting the mould and changing the diehead of the press for each size, comprises a centrally situated hydraulic press A having a ram B surrounded by a series (e.g., four, two being shown in the drawing) of die-heads and mould-handling mechanisms, one for each size of mould used. Each mould-handling mechanism comprises a mould-charging table C, a hydraulic hoist D, a die-head K and a radially acting hydraulic mould-sliding ram E, the sequence of operations being as follows:- a bottomless mould F is placed on one of the tables C and a loose bottom plate M inserted and covered with a sheet of paper. The mould is then charged with concrete which is covered with another sheet of paper. A die-head K of the corresponding size held by a pair of hooks G on the hydraulic hoist D is lowered on to the concrete in the mould and the mould and diehead pushed into the press by the ram E. After pressing, the mould and die-head are withdrawn by the ram E, the mould engaged by a second pair of hooks I on the hoist D, and the mould raised a few inches, the weight of the die-head K stripping the pressed flag from the mould. The first pair of hooks then engages the die-head and this and the mould are raised clear. The flag on its plate may then be removed by an elevating platform truck the arms of which can enter slots M in the table C. The mould F is then lowered and the process repeated. The rams and hoists may be operated mechanically or electrically instead of hydraulically.

Title: Improvements in or relating to films, filaments and other shaped articles made by hardening proteins coagulated from their solutions
IPC: D01F4/00
Filed: 1937-03-24
Abstract: Artificial filaments, films, and other shaped articles made by coagulating protein solutions, and hardened by treatment with p formaldehyde or other hardening agent, are subjected to the action of sulphur dioxide.  The treatment renders the materials more water-repellent and increases their resistance to hot acids particularly hot acid dye liquids.  The sulphur dioxide may be in gaseous form and the treatment may be at elevated temperature, and at reduced or increased pressure.  If desired, the sulphur dioxide may be employed in an aqueous or non-aqueous solvent. Benzene, toluene, ligroin, and trichlorethylene may be used as solvent.  In an example, protein extracted from ground-nuts by treatment with a saline or alkaline solution and precipitation with sulphur dioxide or sulphurous acid, is dissolved in an aqueous solution of urea.  The solution is aged and extruded into a solution of sulphuric acid, ammonium sulphate, zinc chloride, glycerine, and water.  The filaments are hardened with formaldehyde, and then treated with sulphur dioxide gas.  In another example, casein filaments are treated with sulphur dioxide gas.  In another example, filaments produced from ground-nut protein are immersed in a solution of sulphur dioxide in benzene. Specification 467,704 is referred to.
