Patent GB-1065821-A (GB)
Title: Processing strip material
Inventor: BRITTAIN CHARLES PETER
IPC: C21D9/567
Filed: 1963-01-23
Abstract: <PICT:1065821/C6-C7/1> A method and apparatus for continuous thermal treatment of strip material comprises passing the strip through a fluidized bed of granular material with the strip in a substantially horizontal plane, and directing a stream of gas on to the upper surface of the strip to inhibit the deposit of granular material thereon. The apparatus comprises a container 4 wherein is a bed 5 of granular material, maintained in a fluidized condition by a gas supplied to the container through an inlet conduit 6 and perforated shelf 7.  Positioned above the strip 1 is a duct 13, supplied with gas under pressure via the conduit 14, the gas passing through the perforated base 15 of the duct 13 to impinge on the upper surface of the strip 1. The strip enters and leaves the container 4 by way of gland boxes 10, 11 to which high pressure gas is supplied via inlet pipes 12, thus preventing loss of fluidized material through the slits in the container by which the strip enters and leaves. The gas supplied via the conduits 6 and 14 may be recirculated.  If required the fluidized bed may be heated by placing electrical heaters 16, or oil or gas burners in the fluidized bed.  The fluidized bed may be divided into a number of zones, through which the strip passes consecutively, maintained at various temperatures.

Patent GB-924240-A (GB)
Title: Hydraulic extractor
IPC: D06F15/00
Filed: 1962-01-26
Abstract: 924,240. Wringers. G. N. STRIKE. Jan. 26, 1962, No. 2971/62. Class 138 (2). An hydraulic extractor for drying clothes includes an hydraulic ram 13, the head 14 of which is capable of limited tilting, and which, when the ram is projected, pushes up the movable bottom 55 of a wash-laden truck 21, when this is positioned over it on a platform 22, towards a press-head 47 to express water from the clothes. The water leaves through perforated and grooved liner plates 48, 56 fitted on the press-head 47 and truck bottom 55. The ram head 14 comprises a flat plate 42 fixed on a part-spherical member 41 which rests in the similarly-shaped upper end 39 (Fig. 7), of the ram 13, with a pin 43 fixed in the member 41 fitting in an oversized socket 44 in the upper end 39 to limit tilting of the ram head 14. When the ram head 14 moves upwards (through a hole in the platform 22), a rook arm 74 moves a rod 73 to open a valve 58 which permits pressure air to enter a cylinder 68, projecting a stem 69, thereby lifting the platform 22 by means of a cross-head 67, rods 65 and hanger straps 63, until the truck 21 is pressed up against the press-head 47. Pressing a starter button starts an hydraulic pump and, provided the counterweighted sliding access door 20 in the outer casing 18 has been closed, energizes the solenoid of a valve 82 (Fig. 3, not shown), which allows pressure air to open a valve 25 (Figs. 3, 5, not shown), thereby allowing fluid to pass to project the ram 13. The starter button may be released without breaking the circuit, once a switch 119 has been closed by upward movement of the cross-head 67. Timer means are provided. The ram 13 moves in a cylinder 30, the space between being occupied by a sleeve 34 and above that chevron-type packing 90 topped by a gland ring 91. The gland ring 91 has an inner annular grease chamber 92 for greasing the ram 13 and linked by radial ports 93 to an annular grease chamber 98 outside. Annular felt inserts 99, 102 are provided, to wipe the ram surface, in a retainer ring 94 holding down the gland ring 91 and in a rubber water shedder 100 held around the ram on top of the retainer ring 94. Grease is supplied to the outer annular grease chamber 98 from a tank 103 by a pump 104 which is operated by a link 111 pivoted to and driven by the cross-head 67, or by hand. Oil cups 113 are provided for emergency lubrication.

Title: Manufacture of sulphonamide derivatives
IPC: C07C311/37
Filed: 1940-02-16
Abstract: 538,884. Sulphonamido compounds. GEIGY AKT.-GES., J. R. Feb. 16, 1940, No. 2997. Convention date, Dec. 23, 1939. [Class 2 (iii)] Sulphonamido compounds are prepared by reacting the alkali metal salt of a benzenesulphonamide containing a nitrogen-containing group in p-position with isocyanic esters and halogen carbonic esters or amides and, if necessary, converting the nitrogen-containing group into the amino group. Similar compounds are also obtained by reacting a benzenesulphonic acid halide having a nitrogencontaining group in p-position with a carbamic acid derivative, followed, if necessary, by conversion of the nitrogen-containing group into the amino group. The products are useful therapeutically. According to the examples, (1) sodium p-nitrobenzene-sulphonamide is treated with ethvl isocyanate and the product reduced with hydrogen in the presence of a nickel catalyst to give N-(p-aminobenzenesulphon)-N<SP>1</SP>-monoethyl urea ; the Nl-monomethyl and N<SP>1</SP>-monoisoamyl-ureas are similarly prepared ; sodium p-acetylaminobenzene-sulphonamide may be used as starting material, in which the reaction product is hydrolyzed ; (2) p-nitrobenzene-sulphochloride is heated with urea and the product, p-nitrobenzenesulphone-urea reduced with iron and acid ; (3) sodium p-nitrobenzene-sulphonamide is treated with chlorcarbonic acid ethyl, methyl or benzyl ester and the product catalytically reduced using Raney nickel; alternatively, p-nitrobenzene-sulphochloride is reacted with urethane and the product reduced ; (4) potassium p-nitrobenzene-sulphonamide is treated with diethyl-carbamic acid chloride or methylphenyl-carbamic acid chloride and the product subjected to catalytic hydrogenation with Raney nickel ; (5) sodium p-nitrobenzenesulphonamide is reacted with m- or p-nitrophenyl isocyanate, followed by reduction with hydrogen in the presence of nickel to give N- (aminobenzenesulphon)-N<SP>1</SP>-(m- or p-aminophenyl)-urea. Reference is also made to salts of p-benzylamino- and azo-benzene-sulphonamides as starting materials. The Specification as open to inspection under Sect. 91 also describes the use of reactive carbonic acid derivatives in general, including the halides, esters, amides or anhydrides of carbonic acid and mentions carbonyl chloride. This subject-matter does not appear in the Specification as accepted.

Filed: 1963-01-28
Abstract: 984,198. Pneumatic conveyers; unloading ships. INTERCONSULT A.B. Jan. 28, 1963, No. 3425/63. Headings B8A and B8E. In apparatus for delivering pulverulent material in batches from an open compartment, such as the hold 31, Fig. 1, of a ship, having aerators 13, 39 at the base, the material is drawn by suction through a pipeline 17 into a separator 20 and collected in a tank 10 in which it is subsequently fluidized by aerators 24, 30 and delivered under pressure through a conveyer line 19. The aerators 13, 39, 24, 30 are supplied with air from a pressure pump 11 through lines 14, 15, 16 under the control of valves CV, 1, 2, 3, 4, a by-pass line 41 also being provided to augment the supply of air direct to the delivery line 19. The separator filter 20 is coupled by a line 18 to a vacuum pump 12 through a control valve CV8 and auxiliary filter 21. Pressure gauges PS1, PS2 operate to detect pressure variations due to failures in the filter system and control the opening of a bleed valve BV at the pressure pump 11. This stops the supply of air to the aerators 13 so that no further material is drawn through the suction line 17. Valve controlled by-pass lines 47, 48 provide for the auxiliary supply of conveying air from the pressure side of the suction pump 12 to the delivery line 19. The aerator 13, Fig. 3, of the open compartment may have a central air inlet 38 connected by a line 37 to atmosphere and arranged immediately below the inlet end of the suction line 17 to provide an ejector action for dilution of the suspension. In a modification, Fig. 4 (not shown), the system may be duplicated for alternate operation so that one tank 10 may be filled under suction while the other is being emptied under pressure.
