Abstract: 1366895 Shaft seals WEIR PUMPS Ltd 31 July 1972 [26 Aug 1971] 40030/71 Heading F2B The rotary shaft 3 of, for example, a boiler feed pump is sealed by passing the pressurized liquid from the pump casing through a radial labyrinth of axial passages 12, 13, 14 and radial chambers 15A, 15B, at least part of the liquid being vaporized in at least the final chamber 15B so as to inhibit the leakage through the labyrinth before flowing out of this chamber with any liquid through the final passage 14. Leakage progresses radially outwards through the labyrinth to a chamber 17 from which a combined vapour and drain 24 is led to either a flash chamber 25 or to a quenching device 28; alternatively, the labyrinth may be arranged so that the leakage progresses radially inwards instead, Fig. 3 (not shown). A packing 6 may be provided on the impeller 2 and a balance chamber 16 connected to the pump suction 4 provided to control the leakage flow to the labyrinth packing. For sealing the rotary shaft of a horizontal pump, Fig. 4 (not shown), the chamber (17) at the outlet from the labyrinth seal may be provided with separate vapour and drain outlets (31, 30).

Abstract: 948,357. Rotary brushes. HOOVER Ltd. Nov. 22, 1960 [Dec. 1, 1959], No. 40172/60. Heading A4K. A rotary shampoo brush includes a body 10 having means 20 for attaching it to a vertical driving shaft or hub and a ring of bristles 30. The bottom wall 16 of the body within the ring of bristles is brought down to a level only slightly above the tips of the bristles, so as to not only afford a substantially rigid skid surface to take the load from the bristles when the body is pressed down but also to form the bottom of an upwardly opening annular trough 17 for liquid which has holes 21 therein to dispense the liquid on to the supporting surface within the ring of bristles. As shown the bristles 30 are stapled into a groove 29 in an annular back 27 which is retained in the body 16 by means of pimples 28 and shoulders 24. Driving keys 31 fitting in key holes in the body 16 are provided. A ring 22 which slopes downwardly and outwardly prevents liquid being thrown out by centrifugal force and lugs 33 cause the liquid to rotate with the brush. Specification 948,356 is referred to.

The metal may be amalgamated or alloyed with Li, Ca, Mg, Al, Sn, Sb or Zn. It may be in the form of an etched foil. A single cell may contain more than one anode. The halogen may be Cl 2 , Br 2  or I 2  and may be introduced through a current collector of 30-80% porosity made from tantalum or carbon, e.g. graphite, powder, fibre or cloth, with or without a binder. The electrolyte may contain a 0À25M to 2M concentration of a chloride, bromide, iodide, tetrachloroaluminate, perchlorate, tetrafluoroborate or hexafluorophosphate of Li, Na, K, Mg or A1.

Abstract: 1,243,813. Labelling machines. N. W. C. J. NOODER. 5 Sept., 1968 [13 Sept., 1967], No. 42271/68. Heading B8F. An " ironing " machine for heat sealing thermoplastic labels 71 which may be marked, to articles 8 comprises an upper clamping jaw 2, pivotable about a shaft 4 in a double arm lever 41, 42 having a knife edge 22 (Fig. 2) and heating elements 23, and a lower clamping jaw 3, pivoted on a shaft 31 of a piston 52 in a support 5, itself pivotable horizontally to allow the article 8 to be placed on a surface 33 of the jaw 3, the upper and lower jaws being laterally movable relative to each other. A resiliently and adjustably mounted knife edge 11 coacts with the knife edge 22 to provide a scissors action. In operation tape 7, Fig. 2, is fed between the knife edges 11, 22 and is cut as the jaw 2 pivots clockwise about the swivel shaft 4 and then falls free or under the action of an air jet, onto the article 8 on the lower clamping jaw 3 which is now in a raised position so clamping the article between itself and projections 19 on a bracket 18. The heated jaw 2 initiates the adhesion process whilst further clockwise motion of the jaw 2 causes it to move from right to left relative to the label and article so effecting an ironing motion to eliminate any creases in the label. The surfaces 21, 23 are now parallel due to the pivoting action of the jaw 3. The tape 7 may have the thermoplastic material formed as a layer on it or incorporated as threads within it, or the material may be fed jointly with the tape as a foil assisted by spot adhesion or, finally the tape may be formed entirely of thermoplastic threads.
