Abstract: 1,021,771. Electromagnetic relays; electrically released switches. AUTOMATIC TELEPHONE & ELECTRIC CO Ltd. Jan. 8, 1963 [Jan. 23, 1962], No. 2408/62. Heading H2B. In a relay retained set by remanent magnetism a plurality of sealed magnetic contact units 5, 5<SP>1</SP> are mounted between the polepieces 3, 4 of a highly remanent core 2 carrying a winding 1 and a permanent magnet 6 is placed adjacent the units with its magnetic axis parallel to the core. One row of contact units is mounted above the core and another below it. A nickel-silver spring 7 is welded to one terminal of each unit and extends to the other terminal so that all the electrical connections can be made at one end. A ceramic permanent magnet, 6 or 21 (Fig. 2, not shown), is held between the springs 7 and glass envelopes of the units of each row. The terminals of the units are provided with insulating sleeves 11, 12 and the springs 7 are located in slots 10 in a spacer 9 which is interposed between the springs 7 and adjacent terminals. The units are secured to the polepieces by spring clips 13, 14. Covers 16, 16<SP>1</SP> of nylon or ebonite are screwed to the polepieces, the screws passing through holes 18 in spacer 9 and 19 in clip 3. Projections, such as 15, of the covers 16, 16<SP>1</SP> co-operate with recesses in the respective permanent magnets to locate them in position. Assuming that both permanent magnets 6, 21 are polarized in the same sense, Fig. 2 (not shown), and the core is polarized in the opposite sense by its remanent magnetism, all the contact sets will be open. When the polarity of the core is reversed by energizing the coil 1, the contacts close, and remain closed due to the remanent magnetism of the core. The polepieces may be made from an insulating ferrite.

Abstract: 731,152. Treating pig-iron. ALEXANDROVSKY, G. Feb. 1, 1951 [Feb. 2, 1950], No. 2567/51. Class 72. Pig iron from a blast furnace or mixer is subjected to blowing for a time long enough to remove the whole of the silicon and raise the temperature of the metal to a degree at which absorption of nitrogen would commence while it is flowing from the blast furnace or mixer to the conversion apparatus. As shown, the molten metal 4 flowing out of a mixer 1 is subjected to a jet of air from a flat nozzle 5 arranged transversely to the flow of metal. In a modification, Fig. 8, the metal traverses a deepened portion 12 of a trough in which are set pipes 13 through which jets of air, oxygen-enriched air, or oxygen may be blown into the metal. In another modification, Fig. 4 (not shown), the trough may he in the form of steps and the oxidizing gas injected through pipes set in the risers of the steps, the jets being parallel to or obliquely of the flow of metal. The trough may be covered and may be arranged to have a rocking movement so that slag may be removed from the surface of the metal.

Patent GB-230029-A (GB)
Filed: 1925-02-02
Abstract: In developing ice colours with diazo solutions which are neutral or alkaline with sodium carbonate there is added to the said solution a substance which will destroy the caustic alkali present in the padded material without acidifying the bath; such a substance is an alkali bicarbonate or a suitable metal salt or the two together; decomposition of the diazo bath is thus diminished, especially in continuous dyeing or when using tetrazo compounds. According to examples the following shades are produced on cotton (1) bluish red by padding with an alkaline solution of 2 : 3-oxynaphthoic-p-chloranilide and developing with diazotized m-xylidine containing sodium bicarbonate; (2) black by padding with 2 : 3-oxynaphthoic anilide and developing with tetrazotized 4 : 41-diaminodiphenylamine neutralized with chalk and to which magnesium sulphate is added; (3) dark blue by padding with 2 : 3-oxynaphthoic-a -naphthalide and developing with tetrazotized dianisidine neutralized with chalk and to which sodium bicarbonate and zinc chloride are added; the tetrazo solution in the latter case is made up to strength after development of each bath of cotton.

Abstract: 1281862 Stripping waste from cut blanks K W JONES 22 Jan 1970 3138/70 Heading B4B A device for stripping scrap material from e.g. box blanks 4 comprises a stripping disc 3 having tooth-like projections 3a and mounted on a shaft 2 and an annular stripping comb 7 having an outside diameter at least as great as the outside diameter of the stripping disc measured over the teeth and mounted for limited movement relative to the stripping disc and in a plane paralleled to the plane of the stripping disc. As shown several toothed discs 3 are spaced apart by segmental spacers 6 so as to allow the annular combs to slide freely therebetween. The discs are arranged to co-operate with pressure pads 5 e.g. of cork, rubber or brushes mounted on a rotatable drum 1 such that, as shown in Figs 1 and 2, the pads force a scrap portion 5a on to the teeth. The outer surface of the annular comb is forced by the scrap piece below the level of the teeth thereby causing the diametrically opposed surface of the comb to be raised above the level of the teeth (see Figs. 2 and 4). As the shaft 2 and the drum continue to rotate the surface of the comb rides against the drum via the blank 4 thereby forcing the scrap off the teeth. The sawtooth shaped teeth may be replaced by pin-like members.
