Title: Lifting apparatus
IPC: B66C23/06
Filed: 1976-04-30
Abstract: 1536279 Unloading modules from barges; engaging floating modules REDPATH DORMAN LONG (NORTH SEA) Ltd 30 April 1976 [31 Jan 1975 10 March 1976] 4353/75 09556/76 Headings B8E and B8H Apparatus for transferring large modules 124 from a barge 125 or other floating vessel subject to wave action comprises jibs 126 spaced apart by more than the width of the module which are luffable by wires 128 and have winch and tackle lifting gear. The jibs 126 are pivoted at 127 on a drilling or like platform provided with a cantilever section 134 having slots to accommodate the jibs as they are raised into contact with buffers 176 so that in the fully raised position a module can be lowered on to the platform with its centre of gravity over it. The platform has skid beams which allow the module to be moved into position and skidways can be mounted on top of a lower layer of modules to allow positioning of a second layer. Gripper assemblies 162 are provided on a portal frame 126, 165, Fig. 11, and comprise grippers 162A, Fig. 12, slidable on a tube 170 provided with flanges 171, 172 which are emergency stops engageable by buffers 173. Long travel rams in the tube 170 are connected to the lifting beam 168 by a wire strap. In use the tubes 170 are lowered by the lifting winches until their underside is just above bell assemblies 166 engageable with mushroom attachments 159 on the module and then actuation of the rams lowers the tube over the assembly 166 allowing the engagement of the attachment 159. The tube 170 now rides up and down within the grippers 162A until at the top of a large wave lift they are engaged with the tube and lifting is started. As there is a delay before the next large wave a slower lifting speed is acceptable allowing a smaller winch to lift the module clear of the barge safely.

Abstract: 5 - Alkoxy - 6 - methyl - 7 - chlor or 5-alkoxy-6 - chlor - 7 - methyl - hydroxythionaphthenes or reactive 2-derivatives thereof are condensed with isatins of the benzene or naphthalene series or reactive 2-derivatives thereof or hydroxythionaphthenes other than alkoxychlormethylhydroxythionaphthenes or reactive 2-derivatives thereof, the two components being in different states of oxidation. In examples: (1) 5-methoxy-6-methyl-7-chlorhydroxythionaphthene is condensed with 4-methyl-6-chlor-2 : 3-diketodihydrothionaphthene-2-p-dimethylaminoanil or the p-dimethylaminoanil of the former is condensed with 4-methyl-6-chlorhydroxythionaphthene; 2 : 3-naphthoxythiophen may be used as the second component; (2) 2 : 1-naphthisatin-a -chloride, prepared in situ, is condensed with 5-methoxy-6-methyl-7-chlorhydroxythionaphthene; (3) 5-methoxy-6-chlor - 7 - methylhydroxythionaphthene is condensed with 2 : 1 - naphthoxythiophen p - dimethylaminoanil or 8 - chlor-1 : 2 - naphthoxythiophen-p-dimethylaminoanil.  5 - Alkoxy - 6 - methyl - 7 - chlor and 5-alkoxy-6-chlor-7-methylhydroxythionaphthenes may be prepared from the corresponding alkoxychlormethylbenzenesulphonic acids by way of the sulphochlorides, mercaptans and thioglycollic acids. Thus, 5 - methoxy - 6 - methyl - 7 - chlorhydroxythionaphthene of example 1 may be made from 1-methyl-2-methoxy-6-chlorbenzene by treating with chlorsulphonic acid, reducing, condensing with chloracetic acid and effecting ring closure after conversion into the acid chloride. 5-Methoxy-6-chlor-7-methylhydroxythionaphthene may be made in a similar manner from 2-amino-3-methoxy-1-methylbenzene-6-sulphonic acid after replacing the amino group by chlorine.

Title: Improvements in or relating to process and apparatus for annealing sheet glass
IPC: C03B25/08
Filed: 1926-02-16
Abstract: 262,629. White, A. E., (Pittsburgh Plate Glass Co.). Feb. 16, 1926. Glass annealing leers.-Relates to a method of, and apparatus for, annealing sheet glass formed in a continuous ribbon, and consists in providing means for preventing the sheet from " bowing " or warping as it passes through the leer. The glass sheet 3, Fig. 2, passes through a leer 9 on rollers 12 which are arranged at a distance above the. floor. The glass passes through three temperature zones 5, 6, 7, Fig. 1, which may be respectively 25 feet, 40 feet, and 250 feet long. In the first zone, 5, the sheet is re-heated and softened so that it becomes flattened by its own weight. In the second zone, 6, the glass is annealed, and in the third zone, 7, it cools to a temperature at which it can be handled. Hot gases may be passed through flues 15, Fig. 3, in the bottom of the leer to assist in maintaining the temperature, but the principal heating effect is secured by longitudinal gas burners 17 arranged along the sides of the tunnels below the sheet in sections 5 and 6, the flames being directed downwards toward the centre of the tunnel. The hot gases pass upwards around the edges of the sheet and diminish the tendency of the sheet to warp and break and to turn up at the edges, due to unequal cooling. In order further to reduce the tendency of the sheet to bow, a pair of burners 27, 28 are arranged below the centre line of the sheet at about the middle and at the end respectively of the annealing zone 6.

Title: Improvements relating to the production of seamless rolled tubes
IPC: B21B23/00
Filed: 1925-02-18
Abstract: 250,712. Rheinische Apparatebau Ges., and Peters, M. Feb. 18, 1925. Tubes.-Seamless rolled tubes are produced by casting in a rotating mould and then rolling the casting, the heat of the casting being sufficient for the subsequent rolling. The mould a rotated by gearing d, f, and partially closed at its lower end by an annulus b receives a charge of molten metal from the ladle h and trough g. The hollow billet i so formed is passed by a conveyer (not shown) to rolling-mechanism k. In a modification a horizontal mould mounted on a truck is employed. The mould may be fitted with closing rings to produce a casting with tapered ends. The tube i passes from the mould along driven conveyer rollers 3, Fig. 9, and is raked by reciprocating arms 9 to conveyer chains 11, whence it passes, if desired, through a soaking pit 12 to the rolling-mill. The conveyer rollers 4 may be adjusted for height by a plunger and cylinder. If the ingot is too hot for rolling, cooling air may be passed through the soaking pit.
