Abstract: 1,054,863. Annealing glassware. EMHART CORPORATION. Jan. 28. 1964 [Feb. 28, 1963], No. 3569/64. Heading C1M. [Also in Division F4] Glassware is annealed by heating to a temperature near to the annealing temperature, cooling initially at a rapid rate and then more slowly to the strain point, the rate approaching zero as the temperature nears the strain point. and finally cooling further. The process is carried out in a lehr in which at least three temperature zones, through which the ware is carried, are provided. The ware is supported in upright position on the perforated conveyer 10 and is heated first by heaters 20 beneath the belt. It then passes into the heating section wherein it is heated to annealing temperature by gas heaters 18 located in the roof 52. It then passes to the annealing section over a base constituted by a number of chambers 90 to which cooling air is supplied by a blower via channels 112, 114. In the chambers 90, the air is directed by baffles to pass along in the direction of movement of the conveyer while moving in zigzag fashion across the belt. The air leaving the first chamber can be diverted to the front of the apparatus through the passage 120 to assist in the initial heating of the ware; alternatively, the air is diverted through channels 122 to the second chamber 90 and thence through the remaining chambers so that its temperature increases while the ware temperature decreases at a diminishing rate. On leaving the annealing section, the ware passes into a cooling section where cool air is circulated through the hollow roof 174, Fig. 4 (not shown), and through chambers 194 beneath the conveyer, then into a further section where air at room temperature passes through chambers with perforated tops so that the air can escape into contact with the ware, and finally to a delivery section.

Abstract: 1,238,090. Gas turbine rotors. WESTINGHOUSE ELECTRIC CORP. Nov. 19, 1969 [Jan. 17, 1969], No.56650/69. Headings F1G and F1T. A gas turbine rotor has arcuate sealing and locking plates 50 disposed on the upstream side of the blade roots 26 and engaging circumferential grooves 42, 48 in the rotor disc 12 and roots 26, respectively. The groove 42 has a circumferential ledge 44 with an inclined surface 46 and angularly spaced slots 45. Each plate 50 has a foot portion 53 with an inclined surface 56 and a slot 55 arranged so that, prior to insertion of the blade roots 26 in their axial mounting slots in the disc 12, each foot 53 can be inserted radially into the groove 42 to assume the position shown in Fig.4B. The foot is temporarily retained in this position by a clip 61 secured to the disc 12 by a pin 63. When several feet 53 have been inserted in the groove 42 they are slid circumferentially into the Fig.4C position. The blades roots 26 are then inserted in their mounting slots from the downstream side of the disc 12, the clips 61 removed and the plates 50 moved radially outwards to engage grooves 48 in roots 26. Locating bolts 58 are inserted in the disc to engage openings 57 in the plates 50 and prevent inwards movement of the latter. During turbine operation centrifugal force urges inclined surfaces 56, 46 into firm engagement so that the plate feet 53 are forced axially into sealing engagement with the left side of groove 42. Leakage of cooling air supplied through holes 40 and via slots 45, 55 to annular chamber 52 adjacent the roots 26 is thus prevented. This cooling air flows axially past the roots 26 and escapes through an apertured plate (65), Fig.1 (not shown), on the downstream side of the roots. Some cooling air may also flow through holes (30) is disc 12 to cool downstream discs when the rotor has several stages.

A composition for rendering a fabric waterproof and flame resistant consists of an aqueous dispersion containing antimony trioxide in an amount of 5-30% and a polychloroprene latex, emulsified by an alkali metal soap, in an amount of 24-55% solids content by weight of the dispersion. A dispersion stabiliser such as a protein type stabiliser, e.g. casein or a cellulose based stabiliser, e.g. sodium carboxymethyl cellulose may be included. This dispersion is effective to render waterproof fabric treated, prior to or after application of the dispersion, with an aqueous solution of a salt of Al or Zr (e.g. aluminium formate or zirconium acetate), which reacts with the alkali metal soap. The polychloroprene and antimony trioxide serve to render the fabric flame resistant. A further emulsifying agent may be included in addition to that present in the polychloroprene latex, which agent may be formed in situ by separate incorporation in the dispersion of an hydroxide of an alkali metal or ammonium and a hydrophobic organic acid, e.g. naphthenic acid, ricinoleic acid or oleic acid, these reacting to form an alkali metal or ammonium soap of the acid which, as with the soap present in the polychloroprene latex, reacts with the Al or Zr salts. Preferably the dispersion also includes a plasticiser, e.g. petroleum oil, an organic ester such as dioctyl sebacate, a resin such as styrene/ butadiene copolymer, a vegetable oil plasticiser or chlorinated paraffin. Additional compounds which may be included in the dispersion are reactive resins (with a catalyst), rot proofing agents such as pentachlorophenyl laurate, and pigments. Fabrics to be treated include cotton and cotton/terylene (Registered Trade Mark).

Abstract: 1289431 Transferring articles in presses L SCHULER GmbH 19 April 1971 [31 Jan 1970] 20718/71 Heading B3Q In a press in which a cup-shaped workpiece 3 is conveyed from one tool to the next by grippers 12, 13, opening and closing in a direction transverse to that in which they convey the workpiece, a suction member 6 lifts the workpiece from each tool and continues its lifting movement until the grippers have moved into close proximity with or into sliding engagement with the workpiece. Means such as a shoulder 20, Fig. 4, ultimately prevents further upward movement of the workpiece whilst continued upward movement of the suction member 6 detaches it from the workpiece. Then the grippers grip the workpiece and convey it to the next tool in the press. In Fig. 3, the suction member 6 has descended on to the base portion of the inverted workpiece 3 and is lifting the workpiece from the tool 1. In Fig. 4 the gripper members (only the gripper 12 being shown) have approached the workpiece so that as the latter is lifted upwardly by the sucker 6 a flange 14 on the workpiece engages the shoulder 20 on the gripper assembly so preventing further upward movement of the workpiece and causing the sucker to disengage, whereupon the workpiece falls until it engages a stop surface 22 on the gripper. The grippers then grip the workpiece and convey it to the next tool. The surface 22 may be provided with a protective lining material, e.g. foam rubber, to prevent damage to the workpiece. The sucker 6 is one which is operative without a source of vacuum. The link motions providing the movement of the gripper arms are described (Fig. 7).
