Blowing.-Relates to machines for making glass bottles &c. and of the type having a revolving frame or plate carrying a parison mould on opposite sides of its horizontal axis and two sets of neck or mouth moulds carried on the terminals of a hollow double arm. The machine is constructed so as to have a vacuum and a positive) air pressure in the neck or mouth mould parts alternately while in their opposite positions, and air is constantly blown on to the parison moulds for cooling them. The neck-rings 2, Fig. 1, are carried by a hollow double arm 3 on the revolving frame 4, which is mounted on a stationary hollow shaft 6 within bearings 5. The parison moulds 1 are mounted by arms 7 on pins 8 carried by the frame 4, and are opened and closed by arms 10 mounted on pivots 11. Tubes 13, 14 extending through the shaft 6 into a ported plug 15 at the end of the shaft supply suction and compressed air to the passages 3<x> in the arms 3 when the latter are in the upper and lower positions respectively. Air for cooling the moulds is supplied by a pipe 17 to the shaft 6 and passes by a port 18 into an annular port 19 in the frame 4, whence pipes 21 lead to double articulated pipes 22 with nozzles 26. The joints 23, 24 of the pipes 22 are axially in line with the pivots 11 and the joints 25 of the arms 10 respectively. In a modification, Fig. 4, a circular ported plate 30 attached to the swing frame 4 is formed with annular recesses 31, 32 in its face to work over stationary rings 33, 34. Compressed air passes from a connexion 17 to an annular port 35 in the meeting faces of the recesses 31 and ring 33, and then by ports 36 to the joints 23 of the cooling air-blast pipes 22. The vacuum pipe 13 is connected to the upper part of the ring 34, and pipes 37 on opposite sides of the axis of the plate'30 lead to the passages 3<x> of the arms 3 so that, when an arm is in the upper position, its passage 3x communicates with vacuum.

Abstract: 557,107. Lowering apparatus. MORRISON, J. L. April 28, 1942, No. 5670. [Classes 78 (ii) and 78 (v)] Means for dismantling and lowering thwarts or staging 1 suspended in a ship's hold by hangers 3 or other means from deck beams 4 comprise bolts 10 for temporarily suspending the thwarts, the bolts being secured against accidental removal by split pins 14 which can be withdrawn by a remote-control cord 15 when the staging has been lowered and it is desired to withdraw the bolts. The bolts 10 are inserted in existing holes 6 in the deck beams which they fit loosely and are formed with eyes 12 to act as guides for ropes 9 which are secured at 9a and 9b to the hangers 3 and thwarts 1. The weight of the thwarts is then taken by men hauling on the free ends of the ropes 9, the hangers 3 are unbolted at 5 from the deck beams by a person or persons on the thwarts, and the latter are then lowered to the bottom of the hold by paying out the ropes 9. Each split pin 14 is connected by a pin 16 and a link 17 to a cord 15, so that by pulling on the cord 15 the bolt 10 can be rotated through 180 degrees and the split pin withdrawn, after which the bolt 10 can be withdrawn from the hole 6 by pulling on the rope 9. Alternatively the bolt 10 can first be partly rotated by knotting one end of rope 9, drawing this knot up to the eye 12 and pulling on the rope.

Title: New acylating agents and process for their manufacture
IPC: D06M13/358
Filed: 1960-02-17
Abstract: 896,814. Mono-metal salts of cyanuric acid monohalides. CIBA Ltd. Feb. 17, 1960 [Feb. 18, 1959], No. 5685/60. Class 1(2) [Also in Groups IV(a), IV(c) and VIII] A water-soluble mono-metal salt of a 6- halogen - 2:4 - dihydroxy - 1:3:5 - triazine (cyanuric acid monohalide) is prepared by reacting a cyanuric halide, e.g. chloride or bromide, with a water-soluble metal salt of an acid weaker than formic acid, or a hydroxide or an oxide of a metal to form a dimetal salt of cyanuric acid monohalide and neutralizing the dimetal salt with an acid, e.g. HCI. Alternatively, the cyanuric halide and the metal compound are reacted in the correct molecular ratio to form the mono-metal salt directly. Alkali or alkaline earth metal hydroxides or: carbonates may be used, e.g. LiOH, NaOH, or KOH, and the first stage of the two-stage process may be carried out in two stages, by reacting first with weak alkali, e.g. NaHCO 3 , and secondly with strong alkali, e.g. NaOH. The reaction may be effected in aqueous or aqueous-organic liquid (e.g. aqueous acetone) media. The mono-metal salt may be isolated as solid by filtering with, or without, addition of a salting- out agent, e.g. NaCl, or by evaporating, e.g. under reduced pressure at 40‹-80‹C, The mono-alkali metal salts may be reacted with water-soluble salts, e.g. chloride or sulphate, of nickel, cobalt, or copper, or alkaline earth metal, e.g. magnesium, calcium, or barium, to form the corresponding mono-metal salts. Polyhydroxylated fibrous materials, e.g. polyvinyl alcohol, cellulose, regenerated cellulose, linen, or cotton, may be acylated by impregnation with aqueous or aqueous-organic liquid solutions of the mono-metal salts to improve swelling capacity, wet crease resistance, dyestuff affinity, and pest and rot resistance. The solutions may contain buffer agents, e.g. mono- or di-sodium phosphates or alkali metal borates, acid-binding agents, e.g. alkali metal hydroxide, carbonate, or bicarbonate, electrolytes, e.g. NaCl, or Na 2 SO 4 , or non-electrolytes, e.g. urea, or the impregnated material may be subsequently steamed, or subjected to dry heat, in the presence of these agents.
