Title: Improvements in and relating to shaft furnaces
Inventor: ARCHIBALD WILLIAM ANDERSON
IPC: F27B1/12
Filed: 1955-03-29
Abstract: 835,731. Shaft furnaces. BRITISH IRON & STEEL RESEARCH ASSOCIATION. March 26, 1956 [March 29, 1955], No. 9134/55. Class 51 (2). In a shaft furnace, e.g. a cupola or a blast furnace, a number of substantially annular watercooled shelves 13 extend inwardly of the metal shell 12 for a distance of nine inches to three feet, preferably 1¢ feet, so that, in operation, a protective layer 20 of charge material is formed in contact with said shell. The vertical spacing of the shelves is 5-20 feet, preferably 10 feet, and they comprise a number of sections formed of plates 15, 16 and 17 welded together and welded to the shell. Cooling water is continuously passed through said sections, and the shell is cooled by water sprays or other devices. Damaged sections may be removed by cutting away the effected section, and welding over the gap a plate carrying the new section, or the sections may be secured to cover plates riveted or bolted to the shell. A lining of carbon bricks may be fitted in the bosh or the whole shaft may be initially lined with refractory bricks, which are replaced by charge material as they wear. Accretions forming on the lining may be burnt away by admitting air or oxygen through tuyeres spaced around the shaft, or through holes cut in the shell. Specification 299,941 is referred to.
Patent GB-611244-A (GB)
Title: Manufacture and use of resinous condensation products
IPC: C08G12/40
Filed: 1946-03-25
Abstract: Aminotriazine-aldehyde condensation products for impregnating paper and textiles to improve their wet strength and water resistance are prepared by causing an aminotriazine to react with an aldehyde and a bisulphite of an alkali metal or of an alkaline earth metal such as lithium, sodium, potassium, barium, calcium and strontium.  The use of aminotriazines containing at least two free amino groups is disclaimed.  The aminotriazine may be substituted melamines, such as chlorinated, alkylated or phenylated melamines or ammelide.  Di-or tri-alkyl aryl or aralkyl melamines mentioned are 2 : 4 : 6 - triethyltriamino-1 : 3 : 5 - triazines, 2 : 4 : 6 - triphenyltriamino - 1 : 3 : 5 - triazine, 2 : 4 : 6 - trihydrazino-1 : 3 : 5-triazine, 2-amino-1 : 3 : 5-triazine, and 2-phenyl-4-amino-6-hydroxy-1 : 3 : 5-triazine.  Mixtures of triazines may be used.  The aldehyde may be an aliphatic aldehyde such as formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, heptaldehyde, hexaldehyde, furfural or an unsaturated aldehyde such as acrolein or methacrolein, or an aromatic aldehyde such as benzaldehyde and cinnamaldehyde, and the quantity may be 1-6 mols. per mol. of triazine, although an excess of up to 20 mols. per mol. of aminotriazine may be employed.  The resin solutions are kept alkaline during the formation of the resin so that a water-soluble product results.  In the example, 2 : 4 : 6-triphenyl-triamino-1 : 3 : 5-triazine, formaldehyde and sodium bisulphite were refluxed at atmospheric pressure.  An aqueous solution of resin with pH 8.5 was formed.  The product may be recovered by spray or oven drying of the solutions.  They may be dried by heating with or without an acid catalyst.  They may be precipitated from solution by addition of acid, then dried and cured by heating.  They may be precipitated on to paper fibres or textile materials. Specifications 595,366 and 595,367, [Group VIII], are referred to.  The Specification as open to inspection under Sect. 91, the invention includes the use of any aminotriazine, and mentions melamine, ammeline, melam, melem or the like, monoalkyl, aryl- or aralkyl-melamines, 2-chloro-4,6-diamino-1,3,5-triazine, and 6-methyl-2,4-diamino-1,3,5-triazine.  This subject-matter forms no part of the Specification as accepted.

Patent GB-855360-A (GB)
Title: Improvements in hydraulic presses with valves operated by servo-motors
IPC: B30B15/16
Filed: 1958-03-21
Abstract: 855,360. Hydraulic presses. SCHLOEMANN A.G. March 21, 1958 [April 20, 1957], No. 9179/58. Class 69 (2). In a fine control for an hydraulic press, the pressure and exhaust pipes 18 and 19 are connected to the withdrawal cylinder 10 by pairs of valves RES, REL, RAS, RAL in parallel, the valves RES, RAS permitting a quick flow of liquid relative to valves REL, RAL. When the press ram 1 nears one of its required final positions, the corresponding quick flow valve is closed, enabling the ram to be positioned accurately with the use of the low flow valve. Valves PE, PA control the pressure and exhaust pipes to the working cylinder 4. The hydraulic circuit which controls the various valves is shown in Fig. 3. Each valve is connected to a servomotor 30 PE, for example, to which corresponds a slide valve 32 PE, which can be shifted in an upward direction by an electromagnet 34 PE. In order to start the pressing operation, magnets 34 PE, 34 RAL, 34 RAS are energized by manually closing switches and valves 32 PE, 32 RAL, 32 RAS are therefore lifted. Pressure liquid flows from line 75 to servomotors 30 REL, 30 RES. It then passes via valves 32 RAS, 32 RAL to the underneath of servomotors 30 RAS, 30 RAL which rise to open valves RAS, RAL. Since the pressure liquid can only pass servomotors 30 REL, 30 RES when they are in their lowest position, valves RAS, RAL cannot be opened unless valves RES, REL are both closed. The pressure liquid then flows via the open valve RAS and valve 32 PE to the underneath of the servomotor 30 PE to open valve PE. Pressing then commences under the control of throttle valve DR. After the pressing operation is complete, the magnets 34 PE, 34 RAS, 34 RAL are manually de-energized, and the underneaths of servomotors 30 PE, 30 RAS, 30 RAL are connected to exhaust via lines 61, 57, 64, closing valves PE, RAS, RAL. If fine control is required, the switches S/RAS, S/RAL are used (see below). In order to withdraw the press, magnets 34 PA, 34 REL, 34 RES are manually energized. Pressure liquid flows via servomotor 30 PE and valve 32 PA to raise servomotor 30 PA. Since the liquid can only pass servomotor 30 PE when it is in its lowest position, valve PA can only be opened when valve PE is closed. Liquid then flows via the raised servomotor 30 PA and valves 32 REL, 32 RES to the underneath of servomotors 30 REL, 30 RES to open valves REL, RES. At the end of the withdrawal stroke, abutment 11 actuates switch S/RES and magnet 34 RES is de-energized, closing valve RES. Withdrawal then continues at a reduced speed, pressure liquid flowing to withdrawal cylinder 10 via low flow valve REL, until abutment 11 actuates switch S/REL, closing valve REL. The stopping of the pressing stroke may also be effected in two stages in this way by automatic actuation of the switches S/RAS, S/RAL. Specification 838,740 is referred to.

March 23, 1956, No. 9233/56. Class 94(1). [Also in Groups XXI and XXX] In apparatus as in Specification 826,636 comprising a hopper 1 from which explosive is fed to a nozzle by a conveyer screw 2 having a continuation 11 extending through the nozzle, the drive of the screw 11 can be reversed to cut off the supply of explosive to a cartridge case 8 pushed over the nozzle by a ram 10. The spindle of screw 2 may be hollow and may house the drive end of spindle 11 so that the two spindles can be driven independently. As the case fills it moves back into a pocket 7 of a rotary conveyer 5 and when filling is completed the screw 11 is reversed to produce a sudden separation of the main body of explosive from the cartridge, the leading end of the screw being provided with a cutting edge 13. This edge is transverse to the axis of the screw for powder fillings. For plastic charges the edge may be inclined at 15 degrees to the transverse plane.

Title: Improvements in rotary compressors for use with internal-combustion engines
IPC: F02B33/00
Filed: 1926-04-08
Abstract: 250,601. Oesterreichische Daimler Motoren Akt.-Ges., and Raab, L., (Assignees of Kolowat, A.). April 8, 1925, [Convention date]. Movable-abutment type; discharge and suction pipes; back-pressure, reducing. - The air for charging and scavenging an internal-combustion engine is supplied from separate compression chambers in the same rotary compressor. The compressor is of the sliding abutment type with a stationary, eccentrically-arranged, two-part drum 12, 13 a receiving channel 19 being formed at one side of the drum. There are two outlet passages 20, 21 to this channel which communicate in turn with a port 11 in the engine cylinder. A four-cylinder engine is shown, the cylinders 7 revolving about the stationary crank shaft with the outer casing 9 of the compressor. Air enters through a throttled pipe 33 in the crank shaft into the crank case, and passes from these through holes 35 into the interior of the two-part drum. Holes 36 in the drum allow the air to enter the compression chambers between the abutments 17. The pistons control the inlet ports 11 and the exhaust ports in the cylinders, the exhaust ports opening after and closing before the inlet. As the engine revolves, the port 11 of a cylinder first registers with the passage 20 in the channel 19; a compression chamber, say the chamber b, then delivers a charge of scavenging air to the channel which air enters the cylinder. On continued movement, and just before the closing of the exhaust ports, the inlet port 11 registers with the passage 21 and the compression chamber c delivers the charging air. The heads of the abutments 17 have channels 17<a> to allow air to pass freely in and out of the recesses 9<a>. The air may be compressed in the engine crank case before admission to the rotary compressor. The engine and compressor is enclosed in a casing 2 with a detachable cover 32.
