Title: Improvements in and relating to water cooling systems associated with cooling towers
Inventor: DALTRY JOHN HAROLD
IPC: F01K9/00
Filed: 1961-02-09
Abstract: 1,001,101. Water cooling systems for steam condensers. ENGLISH ELECTRIC CO. Ltd. Feb. 6, 1962 [Feb. 9, 1961], No. 4831/61. Addition to 905,924. Heading BIB. The system for cooling condenser-water, claimed in the parent Specification, is modified by connecting a plurality of air-water heat exchange elements 42 to the ports 6, 9 of a single six-way plug valve 3 via mains 56 and 59, and by connecting the tops of the sectors to a conduit 70 which is itself connected, via fall pipe 72 and two valves 73 and 74 arranged in parallel, to the port 6 of the plug valve. For double pass operation, valves 74 and 75 are closed and the water to be cooled, conveyed from the condenser through pipe 35, flows through port 8 into and through port 9 out of plug valve 3 ; the water then flows through mains 59 and pipes 49 into the elements 42. After being cooled, the water leaves the sectors via pipes 46, flows through main 56 and valve 76, passes through the plug valve via ports 6 and 5, and returns to the condenser through pipe 40. For single pass operation, valves 74 and 75 are opened and valve 76 is closed, and the water to be cooled, leaving port 9 of the plug valve, is divided into two streams, one stream flowing to the heat exchange elements via main 59 and pipes 49, and the other stream flowing to the elements via valve 75, main 56 and pipes 46. The cooled water leaves the elements at the top, and flows to port 6 of the plug valve via conduit 70, fall pipe 72 and valve 74. The valve 73 is always kept open to a pre-set extent so as to allow draining of the conduit 70 and fall pipe 72, thereby preventing. their freezing-up. Conduit 70 is provided with automatic air vent valves 71.

Title: Improvements in the manufacture of water-soluble filaments, films and the like from cellulose ethers
Inventor: JOHNSON EDGAR BERT
IPC: D01F2/28
Filed: 1949-02-23
Abstract: Spinning solutions of water-soluble cellulose ethers in a solvent mixture consisting of water and a water-miscible organic liquid or liquids are extruded into a coagulating bath consisting essentially of an organic liquid or liquids miscible in all proportions with the mixture of water and organic liquid or liquids used as the solvent in the spinning solution.  The process is applicable to water-soluble methyl cellulose, hydroxy-ethyl cellulose, carboxymethyl cellulose, and hydroxyethyl ethyl cellulose and hydroxyethyl cellulose. Filaments, films and foils may be produced.  Preferably methyl cellulose as a 15-25 per cent solution in 60-80 per cent by volume aqueous acetic acid is extruded into a bath of acetone, which may contain up to 5 or 7 per cent of water.  The extrusion is preferably carried out at room temperature, but higher or lower temperatures may be used. Other suitable solvents are propionic acid, or other lower fatty acids, methyl alcohol, ethyl alcohol, monoethyl or other lower alkyl mono-ether of ethylene glycol and dioxane.  The coagulating bath may be methyl ethyl ketone, diethyl ketone or other lower aliphatic ketone, octyl or other normally liquid alcohol containing more than five carbon atoms, or a normally liquid hydroxy ether. "Lower" compounds are defined as containing not more than five carbon atoms.  The filaments may be stretched preferably immediately on leaving the bath while still wet with the bath liquid; alternatively they may be stretched while in the bath or at a later stage while softened, e.g. at 290-310 DEG  C.  In an example a water-soluble methyl cellulose of methoxyl content 28.0 per cent and viscosity 15.3 centipoises (2 per cent aqueous solution at 20 DEG  C.) is dissolved in 70 or 80 per cent (by volume) aqueous acetic acid to give a 20 per cent solution.  After filtration and de-aeration it is extruded into a bath of acetone at room temperature.  The filaments are stretched on leaving the bath by 50 per cent of their original length and wound as yarns. The yarns are substantially completely water-soluble and have a dry tenacity of about 1.25 g./denier or more.

Abstract: 648,471. Conveyers; feeding and discharging cans. CHISHOLM-RYDER.CO., Inc. Feb. 21, 1948, No. 5223. Convention date, July 15,1940. [Class 78 (i)] Cans are transferred individually to can carriers on a conveyer in timed relation to the conveyer movement by means of a screw angularly disposed to the conveyer and having. an enlarging spiral thread leading to an enlarged portion provided with a groove continuing the thread but rapidly diminishing in depth for discharging articles radially into the can carriers. Can carriers 25 are mounted on an endless chain 26 carried by sprockets 27 and 28, Fig. 4, sprocket 27 being mounted on a driven shaft 29. A feed conveyer comprises slats 56 on an endless chain 55 disposed parallel to chain 26 and carried by sprockets, one end sprocket 53 being attached to shaft 29. On rotation of shaft 29 chain 55 travels faster than chain 26 owing to the larger sprocket 53. Slats 56 are guided on horizontal rails 57 and 58. Chain 55 moves towards the right,. Fig. 2. The cans 50 are pressed into engagement with the enlarging thread 70 of the screw 60 by a leaf-spring 75 and on reaching the enlarged portion 71 are thrust by the pushing action of the rapidly diminishing groove 73 into the can carriers. The screw shaft, 72 is mounted in fixed bearings 63, 64 and is driven through bevel gears 65, 66 from a shaft 38 having a sprocket 40 driven from a motor, not shown. Shaft 29 is driven through gears 35, 37 from shaft 38 so that carriers 25 move in synchronism with the screw 60. Carriers, attaching to chains.-Each carrier comprises a base plate 85, Fig. 5, having a downwardly projecting lug 86 pivoted to ears 88 projecting outwardly from alternate links of chain 26. Feeding &c.-The receiving edge of the plate 85 is bevelled at 89 to assist smooth transfer from conveyer slats 56 and the opposite edge is indented at 90 and bevelled underneath at 91 to provide a recess to accommodate a transfer wheel 116 having a bevelled edge 123 for transferring cans from the carriers. Front and rear walls 92, 93 of the carriers are shaped to assist transfer and from these on the discharge side rise two posts 95, 96 supporting a swinging top member 98 having a smooth bottom 99 to engage the upper run of a can and an undercut bevel 101 to assist transfer. A lip 103 overbalances the top member but is supported by a lug 106 engaging a guide rail 107. At the transfer point from the screw a depression in rail 107 assists the cans sliding into the carriers after which rail 107 is discontinued as the top is firm on the can. The cans are inverted on the lower run of carriers 25 and then reach the discharge point where rail 107 again engages lug 106 while a cam 115, Fig. 2, pushes the cans on to wheel 116. Guides 162, 163 prevent tilting of the can carriers and similar guides, Fig. 3, are placed around the track to guide the carriers. A set of guards 190, 189 and 78 prevents the cans slipping from the carriers.

Piston packing.-Relates to segmental packing of the type in which parallel grooves c, Fig. 1, with inclined bottoms, are formed in each packing segment C, the grooves being engaged by the heads of inclined spring-pressed plungers, and consists in arranging the plungers B axially and forming them with wedge-shaped heads. The plungers may be arranged in pairs in holes in the piston body A and are positioned by lips z engaging grooves in the piston body. The wedgeshaped joint pieces d between the ends of the segments are also formed with grooves engaged by plungers. The packing may be secured by split junk rings E, formed with flanges D engaging grooves in the piston and each secured by a screw G at the split having an under-cut head engaging a conical seating in the ends of the ring. Alternatively one ring E may be replaced by a flange on the piston. To retain the packing in position when the piston is removed from the cylinder, the segments may carry pins engaging holes or slots in the rings E. In a modification the packing is secured in grooves at the sides of a bull ring by end plates. A separate hole is formed in the bull ring for each plunger. The wedge-shaped joint pieces are not acted on by the plungers, but are pressed outwards by radial springs. The packing for an internal-combustion engine may be arranged in a similar manner, or the plungers B, Fig. 18, housed in holes in the end of the piston skirt, may be retained by a split ring L sprung over lugs in the piston skirt. Alternatively the plungers may be housed in a segmental ring M, Fig. 19, both the ring M and the packing segments C being formed with flanges engaging an undercut groove in the piston body.
