Title: Improvements in coke oven battery
IPC: C10B21/20
Filed: 1946-02-26
Abstract: 608,555. Coke ovens. WILPUTTE COKE OVEN CORPORATION. Feb. 26,1946, No. 6040. Convention date, March 28, 1945. [Class 51(ii)] In a coke oven battery, the coking-chambers 1 are separated by heating-walls A each comprising two rows of vertical flues 3, 4 and a massive wall 5, e.g. sixteen inches or more in thickness, which strengthens the chamber walls to minimize the risk of warping under the expansive force of the coal being coked. The individual flues of the rows 3, 4, are separated by walls, e.g. six inches thick, which stiffen the outer walls against the pressure of the coke. The individual flues 3, 4 are grouped in known manner, in two sets by top headers 14, and are associated with rows of inner and outer regenerators 46, 47 which are so arranged that alternate regenerators are under the chambers 1 and walls 5, the intervening pillars 45 being under the rows of flues. The battery is provided with the usual basement through which air is supplied to the regenerators and in which supply pipes for rich and lean gas and the usual reversal arrangements are accommodated. When rich gas is used for heating the oven, air for combustion is preheated in all the inflow regenerators of all the regenerator rows, but when lean gas is used, it is preheated in the inflow regenerators of alternate rows, air being preheated in the inflow regenerators of the remaining rows. Specification 238,367 [Class 51(ii)], and U.S.A. Specification 1,832,613 are referred to.

Title: Improvements in the production of poly-amide-sulphones
Inventor: FISHER JAMES WOTHERSPOON
IPC: C08G69/48
Filed: 1949-03-07
Abstract: Polyamides containing sulphone groups are prepared by oxidizing the corresponding thioether polyamide with hydrogen peroxide in a fatty acid containing not more than three carbon atoms and having a concentration of at least 70 per cent reckoned on the water and fatty acid initially present in the mixture.  Formic acid is prepared or a mixture of formic and acetic produced, e.g. by adding to 85 per cent formic acid the required quantity of acetic anhydride to combine with the water present.  The polythiotheramide is dissolved in the acid and the required amount of hydrogen peroxide added either as an aqueous solution or in solid form, e.g. the solid sodium carbonate addition product.  The polysulphone-amide may precipitate from the mixture or if not, may be precipitated by adding water or other non-solvent immiscible with the acid.  In examples: (1) 50 parts of a polymer made by heating under nitrogen and then under vacuum hexamethylene diamine and 4-thia-pimelic acid were dissolved in 500 parts of 85 per cent aqueous formic acid and 90 parts 30 per cent aqueous hydrogen peroxide added.  The sulphone polymer precipitated on standing.  The product was diluted with water, filtered, washed with acetone and dried.  Both the thio-ether and sulphone polymers gave fibres from the melt.  An unsuccessful attempt to condense hexamethylene diamine with 3,31-sulphone-dipropionic acid to give a polymer is referred to; (2) as in (1) with heating to 40 DEG  C. before the addition of the peroxide, and subsequent cooling; (3) as in (1) but using a polymer from hexamethylene diamine and 5-thia-azelaic acid with heating to 50 DEG  C. before addition of hydrogen peroxide; (4) as in (1) but using a polymer from hexamethylene diamine and 5-thia-nonane-1.9-dicarboxylic acid dissolved in an acid mixture made by adding to 5 per cent formic acid the required quantity of acetic anhydride to combine with the water present, and twice the theoretical quantity of peroxide, with heating to 60 DEG  C.  The sulphone polymer was soluble in cresol and formic acid and insoluble in water, acetone and methanol; (5) 47 parts of 5-thianonane-1.9-dicarboylic acid in dioxane were added to 20 parts of 60 per cent ethylene diamine in dioxane.  The salt precipitated and after recrystallization from methanol was heated as in (1) to give the polymer which was oxidized as in (4) to give the sulphone polymer; (6) the salt of 7-thia-tridecane-1.13-dicarboxylic acid and hexamethylene diamine was precipitated from dioxane and heated as in (1) to give a polymer which was oxidized as in (4) to give the sulphone polymer. The Specification lists a number of other di-carboxylic acids and diamines from which poly-thioetheramides may be prepared.ALSO:Carboxycyclohexyl-thioglycollic acid may be obtained by the addition of thioglycollic acid to D 3-tetrahydrobenzonitrile, followed by saponification.

Abstract: 1,063,765. Veneering. HARRIS LEBUS Ltd. Jan. 17, 1966 [Feb. 12, 1965], No. 6216/65. Heading B5L. A method of veneering comprises using an adhesive containing water and closing the platens of a press and then momentarily opening and closing the platens at least once during the pressing operation before the adhesive is fully cured, the platens being heated to a temperature such that the water in the adhesive boils and steam and volatile substances escape when the platens are opened, curing of the adhesive continuing during the open period and on closing the platens again. The platens may be heated to only 250‹ F. or to at least 275‹ F. and up to 300‹ F. or higher and be opened at least twice or reciprocated so as to open and close a large number of times. The veneer may be applied to both sides of a core or to one side only, the other side being damped so that the resulting veneered panel is substantially flat or slightly convex; without damping, the panel may be slightly concave. The veneer may be of wood, impregnated paper or metal foil and the core may be cheap wood or compressed fibrous vegetable material such as plywood, blockboard, hardboard or particle board. In one example, the core consists of 5/ 8  inch thick multi-plywood and the veneer is of sapele 0À6 mm. thick applied to one side of the core using an aqueous urea-formaldehyde adhesive at 2 1b. per 100 square feet of core. The temperature of the platens was 300‹ F. and the total time of pressing was 24 seconds with the platens being opened and closed twice at 8 and 16 seconds.

Abstract: 212,916. Trewhella, W. March 14, 1923, [Convention date]. Pneumatic - tyre pressure gauges.-A pair of contact buttons mounted on a tyre straddling member are adapted to engage the tyre at diametrically opposite positions transversely, and means are provided to apply a force to said buttons whereby the tyre is compressed and a resilient element stressed to give by its flexure the pressure indication. Two bowed leaf springs 6, 7 joined at the ends carry at one join a button 1 and in a bracket 10 at the other join a freely sliding screw 3 carrying the other button 2. A bifurcated lever 11 engages by screws 14 a nut 15 on the screw 3 and carries a pivot pin 13 engaging a recess in the bracket 10. The device is placed over the tyre and the button 2 moved by the nut 15 to engage the tyre snugly. The lever is now moved about its pivot 13 until a pivoted indicating member 8 can just move under a stop 9 carried by the outer leaf spring 7. The indication of the pointer 16 on a. graduated plate 17 carried at the end of the springs gives the pressure in the tyre. In Figs. 3 and 4 two curved leaf springs 18 are fixed together at their ends and joined at one end by rivets 19 to one end of a rigid arm 20 interposed between the springs. The other ends are secured by a bracket 23. A pin 24 with a head at each end passes through holes 25, 26 in the leaves and rigid arm respectively, the hole 26 being enlarged to admit of a certain flexure of the spring. In this form, the device is operated until the pin binds when the index 27 will show the pressure on the graduated plate 28. In the form shown in Fig. 7, the bar 29 is rigid and the lever is formed in two parts, a spring 30 secured to a rigid arm 40 pivoted to the nut 32, both spring and arm being bifurcated. The spring 30 is provided with a pivot pin 34 engaging a recess 35 in the bracket 36 and it has a finger 37 engaging a recess 38 in an indicator pawl 39 pivoted to the arm 40.

IPC: F16J15/18
Filed: 1917-05-04
Abstract: 111,081. Heane, A. Jan. 11, 1917, [Convention date]. Boxes; connected to source of high pressure.-Relates to gas-compression plants for refrigerating &c., such as those using ammonia and other volatile gases, of the type provided with lanterns in their stuffing-boxes to prevent the escape of gas into the atmosphere and the entrance of air through the various stuffing-boxes, and consists in maintaining sufficient pressure in the lanterns to prevent escape of gas or entrance of air. In the example shown, 5 is the main comprising cylinder and 6 its stuffing-box containing two sets of packing separated by a lantern 20, which is connected by a pipe 15 with an auxiliary compressor 12 driven in any convenient way. A similar lantern in the stuffing-box of the main regulating valve is counected by a pipe 17<a> to a valve-chamber 26 with which the pipe 15 also is connected. Any gas escaping into the lanterns is withdrawn by the auxiliary compressor and returned to the system through the valve chamber 29. The pressure in the lanterns is thus maintained slightly above that of the atmosphere so as to exclude air from the system. Should the pressure in the lanterns fall, the atmospheric pressure acting on the diaphragm 24 opens the valve 27 to allow gas from the auxiliary compressor to return to the lanterns and thus exclude air from them. Gas from the crank casing of the main compressor may be withdrawn in a similar way.

Title: Improvements in and relating to dynamic coders
IPC: G01D5/347
Filed: 1960-02-24
Abstract: 933,013. Electric selective signalling systems. SOC. GENEVOISE D'INSTRUMENTS DE PHYSIQUE. Feb. 24, 1960 [March 6, 1959], No. 6449/60. Class 40 (1). In a device for converting a physical displacement into corresponding electric signals the tracks of a coded scale are scanned transversely and a pulse is produced each time a " mark " is passed. As described, resiliently mounted photo-electric cells are oscillated across the tracks of a coded scale. The coded scale, Fig. 8, comprises three concentric groups 6, 7, 8, each of nine tracks. The first group of tracks 6 (the hundreds) are marked, as shown, so that each of the ten segments into which the disc is divided contain a different number of marks and thus radial scanning of this group of tracks will produce a group of pulses corresponding in number to the particular sector scanned. The second 7 and third 8 groups of tracks are similarly marked to give units and tens respectively. Each group of tracks is scanned by a single photo-electric cell 20, Fig. 2, the three cells being mounted side-by-side on a resiliently mounted member 18. This member 18 is caused to oscillate by a coil 21 carrying 50 c/s. mains current and a permanent magnet 22, and is so constrained by stops that each cell only scans its associated group of tracks. Two methods of preventing ambiguity errors are described. In the first the scale is resiliently coupled to the shaft and is caused to progress step-by-step by teeth on its rim which cooperate magnetically with a fixed toothed permanent magnet and in the second an additional track on the scale is used to control the position of a scanning slot.
