Title: An improved apparatus for electrode cooking and heating
IPC: F24C7/00
Filed: 1945-01-16
Abstract: 589,363. Liquid resistances ; current measurements. ARNOLD, C. (Therma Electric Heating Manufacturing Co., Ltd.). Jan. 16, 1945, No. 1337. [Class 37] In electrode cooking and heating apparatus the load of a phase supply line is distributed over at least two electrodes, one of which is more deeply immersed, and a measuring instrument with a small range is arranged in this current circuit so that the smaller loads are accurately readable and fine adjustment is facilitated. As shown in section in Fig. 1 and plan in Fig. 2, a threephase electrode heating apparatus comprises an electrode vessel 1 in which smaller electrodes 2 are arranged in a group separately from the main electrodes 3, the bottom 4 of the vessel 1 having a sump or lower part 5 into which the smaller electrodes 2 extend. In one of the supply lines 6 is a working ammeter 7 and in a branch connecting line 8 to the smaller electrodes 2 is a small range ammeter 9 for facilitating fine adjustment. The electrodes 2 may alternatively be arranged in a separate electrode vessel communicating with the vessel 1. The main ammeter 7 may be dispensed with by calibrating the small-range ammeter 9 in terms of total load. A common device may vary the depth of immersion of all the electrodes.

Abstract: 631,022. Stuffing-box substitutes. BYRON JACKSON CO., and STEVENS, A. H. Feb. 12, 1946, No. 1587/48. Divided out of 630,958. [A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 1, 1947.] [Class 122(v)] In a rubber-collar sealing device, a stationary ring 23 is seated in a wall and backed by a resilient ring 25 and is engaged by a ring 24 backed by a resilient ring 26 on the shaft 7. The pressure above the wall is greater than that below and the ring 23 is grooved so that the area of the face 29 exceeds that of the face 30 so that the pressure above the wall serves tc hold the ring 23 on to its seating. For sealing a shaft arranged as described in Specification 630,958 wherein the shaft passes through a liquid seal, a second rubbing collar 24a is arranged to engage a stationary ring 23a seated in a lower wall; a spring 27 is arranged between the rings 24, 24a. Should the pressure outside the liquid seal rise above that of the seal then it will raise the ring 24 from the ring 23' or raise both rings 23a, 24a so that the pressures will tend to equalise.

Title: Improvements in the production of porous sintered metal bodies
IPC: H01M4/80
Filed: 1951-01-24
Abstract: 694,384. Powder metallurgy. BADISCHE ANILIN- & SODA-FABRIK. Jan. 24, 1951 [Jan. 31, 1950; March 21, 1950], No. 1810/51. Classes 83 (ii) and 83 (iv). In a process for making porous sintered metal bodies such as accumulator plates or filters, the powder mass either before, during or after sintering is subjected to local pressure treatment whereby there are formed in the body compacted parts of increased strength of grid or netlike structure, whereupon the body is again sintered, preferably at a higher temperature. In an example, a layer of fine nickel powder 1.5 mms. thick is spread in a narrow elongated mould and sintered in hydrogen at 800‹ C. The sintered band is stamped with perpendicular grooves and re-sintered in hydrogen at 1000‹ C., the powder in the region of the grooves having the density of solid nickel. In a modification, after a first sintering at 950‹ C., depressions in the form of a grating are stamped in the band so that 30 per cent of the pore volume is lost. A further layer of nickel powder is then applied so as to fill the depressions and cover the entire surface to a depth of 0.5 mm., the whole being sintered in hydrogen at 1000‹ C. The grooves may be formed by rolling instead of by stamping. The parts to be compacted may have a greater initial thickness than the other parts. Filler cylinders may be made by bending a strip made as above or by moulding the metal powder to cylindrical form in the first instance.

Abstract: 606,658. Welded pipe-joints. AKT.-GES. BROWN, BOVERI, & CIE. Jan. 23, 1945, No. 1824. Convention date, Dec. 20, 1943. [Class 99 (i)] A universal pipe fitting for connection by welding between pipe ends of the same or different diameters has a number of branches, Figs. 2 and 4, each comprising an extension nipple of tapering form adapted to be cut off at a point appropriate to the diameter of the pipe to be welded. Grooves a of round or other shape may be provided to indicate cut-off points corresponding to various standard pipe diameters. In one form the extensions may be stepped as at b, Fig. 6. The wall thickness may be either constant or decreasing towards the ends of the extensions. For welding a pipe of non-standard diameter to the fitting, the extension may be cut-off between adjoining grooves. In some cases the grooves may be dispensed with. The Specification as open to inspection under Sect. 91 describes also a modification on which a single branch member, Fig. 2 (Cancelled), is used. This subject-matter does not appear in the Specification as accepted.
Patent GB-570205-A (GB)
Title: Improvements in the manufacture and production of artificial filaments, threads and the like
IPC: D01F4/00
Filed: 1942-02-12
Abstract: Artificial filaments are obtained by extruding a solution of casein or similar protein, e.g. protein from soya beans, peanuts, sesame or flax seeds, through a single- or multiple-hole jet or jets into a coagulating liquid, treating the filaments so formed with a hardening liquid containing formaldehyde and ammonia, stretching the so-treated filaments, and then treating them for a second time with a hardening agent without allowing them to contract.  Contraction may be prevented by tensioning the filaments or by effecting the hardening in the presence of salts, e.g. sodium sulphate or calcium chloride. Instead of mixing formaldehyde and ammonia for the preliminary hardening, the compound hexamethylene tetramine may be used.  If desired, the preliminary hardening may be carried out simultaneously with coagulation by adding the hardening agent to the coagulating liquid or by adding hexamethylene tetramine to the casein solution before it is extruded.  In an example, a solution of casein in dilute caustic soda solution is extruded into a coagulating bath containing sulphuric acid and sodium sulphate in aqueous solution at a temperature of 55 DEG  C.  The resulting thread is subjected for 30 minutes while passing over rollers to the action of a solution containing aluminium sulphate, soda ash, hexamethylene tetramine, the synthetic tanning agent of the sulphonated phenolformaldehyde type, "Nerodol" (Registered Trade Mark), and sodium sulphate.  The thread is then stretched in a hot solution of sodium sulphate and wound on to a drum.  It is cut off into staple fibres and then hardened by treatment with a solution made by mixing aluminium sulphate, soda ash, formaldehyde and water.  The cut material is further hardened by immersion in a solution of sodium bisulphate and formaldehyde. Specifications 502,710, 525,158 and 549,642 are referred to.

At points in the track switch where an electromagnet arrangement changes its engagement from a rail on one side to one on the other the rails, as 110, 116, may recede upwardly to their ends in the region of overlap.
