Abstract: 627,564. Two-part couplings. CITROEN, A., and' MINVIELLE, C. G. E. L. April 8, 1946, No. 10802. Convention date, March 8. [Class 38 (i)] Prepared lengths of sheathed mineral insulated conductor are provided at each end with a ferrule coupling and are joined to one another or to other apparatus by intermediate male connectors. The conductors 3 of a sheathed cable 1 protrude through an insulated sealing plug 5 and are soldered into recesses 8 in one end of connector. pins 9. These pins are housed in longitudinal bored holes in an insulating cylinder 13 which is located in a metal sleeve 15 secured to the sheath of. the cable 1. The male connector consists of conductors 21 held in an insulating cylinder 22 located within a metal tube 23. Nuts 24 are held captive on each end of the tube by flanges 25. On assembly, the conductors 24 are gripped by the resilient sockets 11 of the connector pins 9, and the nuts 24 are screwed home on the co-operating flanges 16. The lengths of the prepared elements and of the intermediate connectors are graded so that any desired total length can be built up. Half couplings of the male type may be secured to electrical apparatus to join in this system. The intermediate connector may be modified to provide " Tee " or branched couplings. The Specification as open to inspection under Sect. 91 also discloses a wiring installation built up from the units previously described. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to mining machine cutter chains
IPC: E21C25/28
Filed: 1942-08-04
Abstract: 561,499. Mining-machine cutter-chains. RAMSEY, A. R. J. (Bowdil Co.). Aug. 4, 1942, No. 10857. [Class 24] [Also in Groups XXI and XXII] A mining-machine cutter-chain is formed of links or lugs each comprising two matching parts 20 having an eye portion 21 and a yoke portion 22 with a lateral flange 25 on the top edge and a laterally-extending curved jib portion 26 on the lower edge, the eye and yoke portions being connected by an-inclined offset portion such that the sprocket-engaging surface 27, Fig. 3, is nearer the centre of the eye portion than are the external shoulders 28 of the offset portion; the eye portions 21 are welded together, the welds extending between-points 35, 36, 39, 40, Fig. 3. A bit-carrying body 41, Fig. 4, with its base cut along any one of the planes 44 ... 47 is then welded between the parts 22 of some or all the links ; adjacent bodies 41 are staggered laterally so as to give clearance for bit-holding screws inserted in apertures 43. Links carrying no bit-holder 41 are reinforced by welding a bridge plate 49, Fig. 7, between the parts 22. Reverse bending of the chain may be prevented by contact of the flanges 25 of adjacent links, or by contact of a bridge plate 49 of one link with the bit carrier 41 of an adjacent link, or both. The links are connected together by pins 52 each with a flat face 53, the ends of the pins engaging corresponding apertures 24 in the yoke portions 22, while the centres of the pins engage corresponding bores of bushes 51, Fig. 12, which fit in openings 23 in the eye portions 21 ; the bushes 51 and pins 52 have respectively an internal groove 55 and an external groove 57, the grooves 55, 57 being engaged by a spring ring to prevent relative axial movement. The width of the cutter chain may be varied by welding a spacer between the eye portions 21.

Title: Improved method of treating magnesium-base alloys
IPC: C22C1/02
Filed: 1949-04-25
Abstract: A flux for use in cooling magnesium-base alloys to obtain a fine grain structure comprises mixtures of chlorides of alkali and alkaline earth metals and 0.1-5 per cent of the weight of the alloy of a carbide of an alkaline earth metal, preferably calcium.  In one example, an alloy of 10 per cent Al., 0.1 per cent Mn., 0.3 per cent Zn. and the balance Mg was added to a molten flux of 35 per cent magnesium chloride, 55 per cent potassium chloride, 2 per cent calcium fluoride and 9 per cent barium fluoride and the temperature raised to 1400 DEG F.  Commercial calcium carbide was thrown into the melt causing refinement of the grain of the resultant castings.  In another example, an alloy of 9 per cent Al, 0.1 per cent Mn, 2 per cent Zn and the balance Mg was treated similarly.  Specification 608,942 is referred to.

[Class 44) A mortice lock comprising two parallel spaced locking bars 2 with rack teeth 4 on their inner ends engaging a pinion 5 mounted in the casing, has a key-lock 10 on each side of the door. Preferably both locks are operated by a single key 12 and are of the type having revolving barrels 11 controlled by pin tumblers. The inner ends of the bars 2 are supported between guides 3 in the open-ended casing 1 ; the outer ends are guided in slots 7 which form part of the recess in the door. When the bars are extended by clockwise rotation of the pinion 5 their outer ends engage in recesses 8 in the door frame.

[Class 66] A can or like metal container is provided below the end seam 3 with a score or weakening 2, Fig. 2, extending wholly or partially around the perimeter of the can, and intended to enable opening to be effected by forming, by means of a tool, an incision at a given point of the score and thereafter using the tool to apply leverage upwardly to break open the end by applying tension across the score. To avoid buckling-in the can at the point where the incision is made a second short score 2b, Fig. 4, may be provided above the main one at the place of opening. The can may be provided with an internal collar 12, Fig. 6, which may be movably engaged in a bead 10 on the body so that it can be raised above the severed edge of the can after opening. A re-closure cover may be provided which may seat on the rim 3 before opening and engage a bead such as 10 thereafter, or a cover having parts of stepped diameters adapted to engage in the recessed end and either externally or internally of the opened can may be provided. Several forms of tools for effecting the opening are described.

Abstract: 559,787. Treating wool; resinous condensation &c. products. SPEAKMAN, J. B., BARR,. T., and IMPERIAL CHEMICAL INDUSTRIES Ltd. Aug. 21, 1942, No. 11780. [Classes 2 (iii) and 15 (ii)] Wool fibres, yarns, or fabrics are stiffened ; rendered resistant to felting or shrinking, and rendered less readily absorbent of water vapour,. by exposing them at elevated temperature but below 100‹C. to the combined action of water vapour and the vapour of a volatile vinyl orvinylidene compound, e.g. an ester of acrylic or methacrylic acid, styrene, or a vinyl ester,. so that the vinyl or vinylidene compound undergoes polymerization within the wool fibres. Preferably the wool material is wetted out with water before exposure to the mixed vapours. It may be immersed in water or water containing a wetting agent or a polymerization catalyst such as ammonium persulphate. or it may be exposed to water vapour alone before exposure to the mixed vapours. The proportion of vinyl or vinylidene compound incorporated may be 40-200 per cent. of thewool. In an example, wool fabric is wetted out in water, wrung until about 100 per cent. of water remains, and wound in open width into a loose roll which is suspended above a mixture of methyl methacrylate and water contained in a water-jacketed vessel fitted with a reflux condenser, the fabric being placed so that it is not contaminated with condensate. The space around the wool is heated to 90-95‹C. A little ammonium persulphate may be added to the wetting-out water, and a little copper rosinate, to act as a non-volatile polymerization inhibitor, may be added to the liquid mixture of water and methyl methacrylate. Specification 418,449 is referred to.
