Patent GB-911599-A (GB)
Title: Improvements in apparatus for the heat treatment of sheet materials
Inventor: BENNETT WILLIAM DOUGLAS
IPC: D06B19/00
Filed: 1958-02-07
Abstract: <PICT:0911599/IV(a)/1> <PICT:0911599/IV(a)/2> Sheet material 36 to be heated or cooled, such as textiles, nylon or polyester or polyvinyl resins to be heated for stretching, is passed up between two rollers 34 (rubber-coated or yieldably mounted) through a slot 32 into a bed of fluidized sand or ballotini which bed, in the apparatus shown, is heated by electrical elements 15.  The sheet 36 passes from feeding and stretching rollers through the apparatus to upper feeding and stretching rollers and the movement causes the sealing rollers 34 to rotate, or one or both may be driven.  One of the rollers has a handle for manual operation.  The bed container 10 is surrounded by glass wool 13 and there are pipes 38 in the rollers 34 for supplying cooling water.  The fluidizing gas, such as air, passes from an inlet 26 to a ring passage 21 around the apparatus and thence through holes 28 to passages 23 from which it passes through the porous floor 30, of sintered stainless steel, of the bed container 10.  Gas is also fed, to prevent leakage of particles from the bed, to the space 43 between the sealing rollers 34 and concave members 39 adjacent to the rollers and at the ends of the rollers to the space 41 between and above the rollers and the space between the roller ends and a plate 70 urged by springs 72 against the roller ends adjacent the bearings 80. This sealing gas enters through pipes 47, chambers 49 and sintered steel plates 51 and, at the ends, through a pipe 69 and ducts 74, 76, Fig. 2, in the end plate 70.  Its passage from the space 41 is controlled by two slides 56 which can be moved to expose more or less of sintered steel plates 52 through which some of the gas may pass to breather passages 25 which pass it outside the apparatus or to the ring passage 21 instead of up the slot 32. Slidable plates 44 have edges close to and shaped to the rollers for closing the space between the rollers and the concave members 39. In a modification, Figs. 3 and 4 (not shown), the sealing gas passes through the spaces over the rollers from the chambers 49 through a porous layer of each of two composite plates almost contacting the outside edges of the rollers for sealing purposes. The spaces over the rollers contain sealing rods (which may be in separated lengths to allow for expansion) which are parallel with the rollers and are lifted by the gas to contact the concave members 39.  This modification has no breather passages 25 and the ends of the rollers have sleeves spring-urged outwardly against end plates of polytetrafluorethylene for sealing.  Barrier rings of greater diameter than the shaft are mounted on the roller shafts between the bearings 80 and the rollers and there may be wear collars at the roller ends.  Figures are given for temperatures, gas pressures, particle sizes and stretch of sheet.

Filed: 1942-03-31
Abstract: 556,434. X-ray apparatus. GOLDFIELD, E. R. March 31, 1942, No. 4287. [Class 98 (i)] [Also in Group XXXVII] A fluid tight housing 14 for an X-ray tube has a flexible bellows 19 to accommodate expansion of the contained fluid under temperature changes. A switch, of the snap-action toggle type, is operated by the relative movement of sleeves attached to the bellows and casing to cut off the current to the tube on undue heating. As shown on heating, the bellows head 19a moves to the left, taking with it the switch body 33, sleeves 31 and 38, causing a button 25 to project from the end of the casing. After a certain distance, a flange 25a meets an inturned part 26 of the end plate and movement of the button and sleeve 38 is arrested. Further expansion causes a bell-crank 36a, 36b to turn on its pivot, snapping over contacts 35. The operation is reversed on cooling down. The button may have a distinctive band 30 marked on it to show that the switching point is nearly reached.

Title: Method and arrangement for obtaining and utilizing sulphur dioxide from blast furnace slag
IPC: C01B17/50
Filed: 1920-02-16
Abstract: Sulphur dioxide sufficiently concentrated for the production of sulphuric acid is obtained by oxidizing the sulphides in liquid blast-furnace slag by passing a limited amount of air or oxygenated air over or through the slag, or both, or by adding an oxidizing-agent such as calcium or magnesium sulphate to the slag, or by both adding such an agent and treating with air.  The oxidizing-agent may be preheated and may be used in molten condition. For this purpose, calcium sulphate may be fused with a small proportion of a flux such as sodium chloride or calcium fluoride. The treatment of the slag is such as not to cause solidification; for instance, the air may be blown through the slag, and the hot air arising therefrom may be passed over the slag as it runs along a covered channel in counter-current.  The liberation of the sulphur dioxide may be facilitated by stirring or by blowing in heated air, but the quantity of air should not in any case be such as to yield a product containing less than 2 per cent of sulphur dioxide by volume. The slag may be treated in a slag-pan provided with a hood, dip-pipe, and gas outlet, or in one or several covered slag sumps disposed in the slag-run.  The treated slag is suitable for the manufacture of slag cement, slag wool, &c.  Reference has been directed by the Comptroller to Specifications 11544/99 and 2405/08, [both in Class 22, Cements &c.]
