Title: Pyrometer sheath and method of making the same
IPC: G01K1/08
Filed: 1925-04-04
Abstract: 251,750. Johnson, W. C. April 4, 1925. Tubes. - A tubular pyrometer sheath is made from sheet chromium steel having at least 15 per cent of chromium by rolling the sheet into tube form and electrically arc welding the edges with a welding-material of substantially the same composition as the material of the tubes. The welding-material 12, Fig. 5, is permitted to flow through the seam to form a rib 13 which is stated, when a mandrel is not used, to cause the cooling by the air inside the tube to be such that blowholes are eliminated. A grooved mandrel 14 of brass or copper may be used, such mandrel forming a chill for the inner side of the welding-material. In the joint shown in Fig. 7 the edges are scarfed to form a V-shaped opening into which the welding-material flows. The end of the tube may be closed as shown in Fig. 6 by forging it down to a point, thus increasing, the wall thickness, the end opening 21 being closed by welding material 22 of the same composition as before, electric arc welding being preferably employed. The end may also be closed as shown in Fig. 8, the tube being in this Figure shown in position in the wall of a furnace and containing a thermocouple 20. Pyrometer sheaths of cast chromium steel are referred to.

Title: Method of producing nodular cast iron
IPC: C21C1/10
Filed: 1949-04-04
Abstract: Nodular-graphite cast iron is produced by melting a charge of iron having carbon and silicon contents which would produce gray iron, adding a carbide metastabilizing agent to the melt, graphitizing the melt and finally pouring.  The carbide metastabilizer may be lithium, calcium, barium, magnesium, strontium, or cadmium alloyed or not with iron, copper, zinc or manganese.  A wedge test, as described in Specification 590,344 may be made on the "as melted" charge and metastabilizer added, after which a wedge test should have a minimum value of more than five times the "as melted" test and a maximum value of twice the thickness of the casting to be made.  After graphitizing a further wedge test should have a maximum value equal to the thickness of the casting and a minimum value of 3/32 for 1 inch thick castings, 6/32 for 2 inches thick castings and 8/32 for castings of thickness 3 inches or more.  The graphitizer should be added during the "life" of the metastabilizer and the temperature range in which additions should be made should be between 15 per cent and 20 per cent superheat over the melting temperature.

Abstract: Pentaenes are obtained by condensing b -ionone and an ether of 1-hydroxy-3-methyl-6-halogeno-hexene-(2)-yne-(4) in the presence of zinc, cadmium or magnesium, subjecting the ether of 1-hydroxy-3 : 7-dimethyl-7-hydroxy-9 - (21 : 61 : 61 - trimethyl - cyclohexene - (11)-yl) - nonadiene - (2 : 8) - yne - (4) obtained to hydrogenation until one mole of hydrogen has been added to the triple bond of said hydroxy compound and subjecting the hydrogenation product to treatment with a dehydrating agent.  Alternatively, the ether of 1-hydroxy-3 : 7-dimethyl - 7 - hydroxy - 9 - (21 : 61 : 61 - tri methyl - cyclohexene - (11) - yl) - nonadine-(2 : 8)-yne-(4) may be subjected to dehydration before hydrogenation. The dehydration may be effected in the presence of a diluent by esterifying with an organic acylating agent and splitting off acid by heating, preferably in the presence of an alkaline agent or by treatment with phosphorous halide and splitting of hydrogen halide from the halogeno compound so formed.  The hydrogenation may be effected in the presence of a palladium catalyst. Detailed examples are given.  A sample has been furnished under Sect. 2 (5) of Vitamin A-methyl ether made by the alternative method above.

Title: Improvements in or relating to degumming vegetable fibres
IPC: D01C1/02
Filed: 1934-03-28
Abstract: Vegetable fibres such as sisal, hemp, ramie, flax, jute, manila, or china grass are degummed by treating them with a bath containing sodium and/or potassium caseinate, washing them to remove saponified and emulsified gums and pectins, and treating the washed fibres with acid to restore the colour and strength of the fibres by fixing any gums and resins left in them and finally washing the fibres free from acid and drying them.  The caseinate is made by boiling 10 parts of casein with 90 parts of caustic soda or potash and 100 parts of water until the casein is degraded.  A proportion of caustic alkali may be substituted for some of the caseinate in the bath.  The decorticated or retted fibres may be boiled for 1--3 hours or steeped for 12 hours in a bath containing 8--20 per cent sodium and/or potassium caseinate, and if desired 8--20 per cent caustic soda or potash. After separation from the bath and washing the fibres may be steeped for about half an hour in a bath containing about 1--5 per cent acetic acid.  For rapid degumming the fibres may be boiled for 1 hour in a bath containing 10 per cent sodium and/or potassium caseinate with 5 per cent caustic alkali.

[Also in Group XXV] A coffee-maker of the pressure type comprises an open top boiler 10 communicating through a lift pipe 32 with a ground coffee receptacle 26, which is located above the liquid level and communicates through a second lift pipe 66 with the interior of a collecting vessel 12 detachably engaged with the upper edge of the boiler 10, the first lift pipe 32 being rigidly attached to a partition member i.e. the base of the receptacle 26, part of which abuts or engages in an annular packing between the boiler and collecting vessel, and the second lift pipe 66 being rigidly attached to the base of the collecting vessel 12, removal of which uncovers the receptacle 26 for filling. A flange 24 of the receptacle 26 fits removably in a recess 20 in the thickened top edge 18 of the boiler 10. The perforated upper end of the pipe 32 extends into the receptacle 26 to receive perforated, central, tubular projections 41, 43 of curved screen members 40, 42. By using one or both screens, which are of different volumes, and by interchanging and reversing them or removing both, varying quantities of coffee may be placed in the receptacle 26, which is then covered by a filter paper 44. The collecting vessel 12 comprises an outer wall 52 spaced from an inner vessel 54, the outer wall 52 having a downwardly extending flange 50, between which and an annular shoulder of a perforated curved plate 48 secured to the base 58 of the inner vessel 54 a rubber gasket 46 is compressed. The vessels 10, 12 are releasably held together by diametrically opposed pins 98 on the vessel 12 each being forced into one of two slots 94, 96 in opposed discs 90 pivoted on the boiler 10. The slots extend symmetrically round, but eccentrically with respect to, the pivots 88 of the discs from a common opening 92, so that locking is effected whichever way the handles 108, in which the discs are embedded, are turned. The locking results in compression of the gasket 46 to form a fluid- and gas-tight seal. An outlet 68 from the collecting vessel 12 is opened by pressing down a spring-controlled valve member 74. In a modification, Fig. 3, the lower edge of the outer wall 52 of the vessel 12 is extended to form first a shoulder 132 surrounding a gasket 134 which encases the rim of a ground coffee receptacle 136, and then a cam lug 124 of a bayonet coupling, the co-operating cam lug 122 being secured to the top edge of the boiler beneath an outwardly turned flange thereof on which the gasket rests.
