Title: Drying apparatus for drying paper-and pulp-webs
IPC: D21F5/02
Filed: 1964-03-18
Abstract: 1,059,410. Drying cylinders. WARTSILA-YHTYMA OY WARTSILA-KONGERNEN AB. March 18, 1964 [March 19, 1963], No. 11373/64. Heading F2U. In a rotating steam-heated drying cylinder for drying paper and pulp webs, wherein steam is introduced through an inlet pipe 15 and condensate is removed by syphon pipes 23 connected to an outlet pipe 10, the inlet pipe 15 feeds a single longitudinal or, as shown, several equally spaced adjustable nozzles 21 which extend over substantially the entire cylinder drying width and discharge steam in a direction opposite to that of the cylinder rotation at high velocity so as to obtain an effective heat transmission to the cylinder shell 2 and loosen the rimming condensate. The cylinder is mounted by trunnions 5, 6 integral with the cylinder ends 3, 4. The internal surface of the shell is machined rough or grooved to increase internal surface area. To regulate the drying effect across the cylinder the nozzles 21 are adjustable or closable by pneumatic or hydraulic membrane or plunger servomotors controlled outside the cylinder when the machine is running, or, as shown, by needles 22 when the machine is stopped. When the nozzles are closed at some part the condensate forms an unbroken ring locally preventing effective heat transmission. The nozzles are arranged on a longitudinal duct 20 connected to branch pipes 19. The branch pipes 19 and the syphon pipes 23 are respectively connected to compartments 13, 14 of a divided chest 7 which is stationarily supported by a pipe 8 and the outlet pipe 10 in bearing housings 9, 11. Alternatively, the chest 7 may be supported from outside the cylinder at one end only, its other end being supported by a bearing inside the cylinder, thereby providing for steam inlet and condensate outlet through the same trunnion. The inlet pipe 15 is connected to the compartment 13 through an injector 16, 17  by which remaining uncondensed steam may be re-circulated, to reduce pressure, through holes 18 in the pipe 8. Alternatively, the remaining steam may be led away with the condensate for use with reduced pressure parts of the system.

Abstract: A linear copolyester is derived from a glycol of formula HO(CH2)nOH, where n is 2-6, terephthalic acid, isophthalic acid and at least one pair of acyclic dicarboxylic in the molar ratio 0.5 to 2.0 and each having the formula HOOC-CH2-X-CH2-COOH where X is a divalent radical containing in the chain of atoms linking the two -CH2-COOH groups 2 to 8 atoms of which not more than 2 atoms are oxygen atoms and the rest are hydrocarbon carbon atoms and having from 0 to 3 hydrocarbon carbon atoms in side-chain substituents, the acyclic dicarboxylic acids of said pair (or each pair if there be more than one) differing from one another by at least 3 atoms in the chain of atoms linking the -CH2-COOH groups, the molar proportions of the acid components of said copolyester being within the following ranges: terephthalic acid 20 to 60 per cent, isophthalic acid 15 to 50 per cent and acyclic dicarboxylic acids 10 to 50 per cent.  The copolyesters are made by the melt polymerization of a mixture of bis-(hydroxyalkyl esters of the acids.  They are used as adhesives for joining a lamina of a polyalkylene terephthalate to another lamina (see Group VIII) or as a binding agent for a mat of non-woven fibres or as an adhesive for replacing solder in fabricating metal containers.  To this end they may be used dissolved in a solvent (e.g. butyrolactone, benzyl alcohol, dimethyl sulphoxide, dioxane, dimethyl formamide, diacetone alcohol, chloroform, cyclohexane, methyl ethyl ketone preferably in admixture with toluene or dioxane, methylene chloride, nitromethane, tetrahydrofurane, toluene or carbitol acetate) or admixed with a plasticizer (e.g. chlorinated diphenyl or an alkyl or aryl phosphate).  In examples copolyesters were prepared by polycondensing the bis-(hydroxyethyl) esters of terephthalic, isophthalic, adipic and sebacic acids in presence of ethylene glycol and antimony oxide; the bis-(hydroxyethyl) esters of terephthalic, isophthalic and sebacic acids being prepared by reacting the dimethyl esters of the acids with ethylene glycol in presence of calcium acetate and the bis-(hydroxyethyl) ester of adipic acid being prepared by reacting the free acid with ethylene glycol.  Specification 578,079, [Group IV], is referred to.

Title: Improvements in or relating to mechanisms for discharging articles from a conveyor
Inventor: SUTCLIFFE THOMAS DESMOND
IPC: B65G47/84
Filed: 1950-05-09
Abstract: 703,063. Endless belt conveyers. SUTCLIFFE, Ltd., R. April 16, 1951 [May 9, 1950], No. 11575/50. Class 78 (1) A mechanism for discharging articles from a conveyer such as a belt conveyer, comprises a framework supporting at least one article receiving member and releasable means for locking the member or each member in turn in a loading position over the conveyer, the means being released by the article when it has been received by the member to allow the latter and the article to be moved into a position in which the article is discharged from the conveyer and the member. Fig. 1 shows an arrangement for discharging unfired green bricks from a conveyer belt 7 comprising article receiving members 1 secured to arms 2 mounted on a central member 3 rotatable about a spindle 4 supported between a bracket 5 and a base 6. The end wall 12 of each member 1 has a tubular extension 13 in which slides a plunger 14 controlled by a compression spring 17 engaging the wall and the plunger head 15, the plunger head carrying a buffer plate 16. The initial position of the plate 16 is selected so that a brick will protrude slightly from the open end of the member 1. This member 1 is normally locked in its loading position by a lever 18, pivotally mounted at 20, having a hookshaped arm 19 engaging a catch 24 secured to the bracket 5. A member 26 slidable in a sleeve 27 secured to the bracket 5 prevents the arm 19 bouncing off the catch 24 when a member 1 reaches the loading position. When a brick moves into the member 1, it engages the buffer plate 16 and through a link 22 disengages the arm 19 from the catch 24 whereby the member 1 rotates clockwise to a position above a shoot 6a where the brick being only partially supported by the belt, overbalances and slides down the shoot. At the same time, another member 1 has been brought into a loading position in which it is locked, to be unlocked eventually by the next brick on the belt 7. When the bricks are placed in rows on the belt, a number of discharge mechanisms are arranged along the length of the belt, each to discharge bricks from a particular row.

Abstract: 492,093. Wire resistances. PONT, J. S., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Jan. 3, 1938, No. 118/37. [Class 37] A resistance thermometer for use at high temperatures such as 500- 1000‹ C. consists of an open helix 2 of platinum or other resistance wire housed in a refractory sheath 8, the ends of the helix being attached to thicker lead-in wires. 5, 6. The resistance wire is first closely wound on a former ; it is then removed from the former and its ends are attached to the lead-in wires. The helix is then inserted into a refractory sheath, which is of material having little or no free silica, such as sillimanite, porcelain, or recrystallized alumina. The helix is stretched during or after introduction into the sheath, so as to separate the turns, and may then be annealed. The interior of the sheath is then packed with a refractory cement which does not attack the resistance wire at high temperatures, for example alumina or zirconia cement. The refractory sheath may have a single channel as shown in Fig. 2 or two parallel channels as shown in Fig. 4, the middle portion of the helix being pulled out as shown at 11. Alternatively this portion may remain undistorted or the helix may be divided and the portions joined by a thicker wire.

Abstract: 662,673. Jet propulsion plant. BRISTOL AEROPLANE CO., Ltd. April 25, 1950 [May 4, 1949], No. 11949/49. Class 110(iii) [Also in Groups XXIX and XXXIII] A gas turbine power plant having a turbine rotor 13, Fig. 1, driving the compressor 14 and a rotor 11 driving a variable-pitch propeller 10, has the latter so controlled that the speeds of the two rotors are maintained in a required ratio. The casing 20 of a differential hydraulic pump is driven by the rotor 11 whilst a gear wheel 22 of the pump is driven by the rotor 13 so that when the rotors are running at the required speed ratio, the pump discharges sufficient liquid to a chamber 33, Fig. 2, to make up for leakage through an outlet 41 and to balance a spring 31 acting on a control valve 28 so that the latter is maintained in a position in which the propeller pitchchanging motor 25, which is supplied by a pump 27, is stationary. A second liquid at constant pressure is delivered through a pipe 35 and a valve member 39 to the chamber 33 and the arrangement is such that a change of delivery pressure from the differential pump due to a variation in viscosity of the liquid acts on a piston portion 37 of the valve member 39 to vary the flow of the second liquid to compensate for the change in viscosity . The valve member 39 also checks hunting when the control valve 28 is operated since any change of pressure in the chamber 33, consequent upon a variation in output of the differential pump, causes actuation of the valve member 39 such as to lessen the change of pressure in the chamber. The control valve is surrounded by an adjustable sleeve 29 by which the propeller may be feathered or,reversed in pitch. The speed of the turbine rotor 13 is controlled by a governor 16 which regulates the quantity of fuel supplied to the combustion equipment and whose datum is adjustable by a hand lever 18.
