Title: Improvements in or relating to apparatus for use in carrying out exotheric chemical reactions under high temperatures and pressures
IPC: C01C1/04
Filed: 1920-03-09
Abstract: 140,089. L'Air Liquide, Soc. Anon. pour l'Etude et l'Exploitation des ProcÚdÚs G. Claude. Dec. 24, 1918, [Convention date]. Ammonia, catalytic production of from nitrogen and hydrogen; catalytic apparatus. - In apparatus for effecting exothermic reactions in gases under high pressures and at high temperatures, the gases are led into the apparatus through a tube embedded in the catalyst, and which also serves.to convey electric current into the apparatus for starting or promoting the reaction, the tube itself acting as the heating- element and also as a heat-interchanger between the products of the reaction and the incoming gas. The invention relates particularly to apparatus for use in the synthesis of ammonia. In the apparatus shown, the reaction tube T' containing the catalyst is enclosed in a pressure-sustaining tube T, and the latter is protected by molten material in which are immersed a pile of rings of heat-insulating material. The reaction gases are led in through the tube t, which forms the heating-element and is provided with a series of barbs to support the catalyst and with earthenware or china disks D to obviate short-circuiting; the gases pass through the whole length of the tube and escape through an opening O at its lower end. In the free space above the catalyst the tube is coiled to provide a heat-interchanger, and to prevent undue rise in temperature, this part of the tube is thicker and of a better conductor, or the spirals are short-circuited. In use, a heavy current of low voltage is passed through the tube in order to produce a temperature gradient between the reaction-tube and the outer wall T comparable with that obtaining during the normal working of the apparatus; by this, the protective material is fused regularly, and undue strains on the tube T' are obviated. Specifications 140,083 and 158,593 are referred to.

Title: Improvements in and relating to paper winding machines
IPC: B65H19/22
Filed: 1947-03-19
Abstract: 626,758. Feeding webs. ROEN, G. March 19, 1947, No. 7620. Convention date, March 23, 1946. [Class 100 (i)] In a winding machine for winding paper sheets unwound from a supply roll on a rotating spindle which carries the roll during its rotation, the drive of the spindle is disconnected automatically dependant on the quantity of paper rewound, the spindle is withdrawn axially from the rewound roll which is then received on a displacing means and the end of the web is cut by a movable member which engages the web between the roll and spindle to move the web into contact with the spindle for a new rewinding operation. A paper web 30 is wound on a spindle 6 from a supply roll 29 over guide rollers 3, 4, 5; the spindle 6 is driven intermittently by a motor 7 through a clutch 8, pulleys 12, 13 and 14, belt 11 and a further clutch 51, 51<SP>1</SP>. When each roll is complete the spindle 6 is moved axially by a piston 46 within a cylinder 45. The piston 46 is moved by a control valve 41 operated by compressed air or fluid. The control valve 41 is actuated by a lever 39 moved by an electromagnet 35 operated by a switch 31 which is moved to operative position when the roll reaches a predetermined diameter. The completed roll 29 drops on to supporting rollers 55 and 56 causing a lever 59 to move downwards so that a cam roller 66 engages a cam 67 and a further cam 62 on the lever 59 operates a switch 69 which through a magnet 80 closes a clutch 85 to drive a cam-shaft 68 through a worm gear 86 driven by pulleys 8 and 87. An electromagnet 35 connected in parallel with an electromagnet 34 actuates a brake lever 26 and band 25 through a wire 36 to brake the supply roll 29. The spindle 6 is returned to its initial position by actuation of the plunger 40 of the control device to the left by a spring 38. A cam 93 on the cam-shaft 68 engages a roller 94 and causes movement of levers 98-99 from the position shown in Fig. 1 towards the spindle 6. Levers 98-99 are connected by a slotted tube 100 which during the movement inwards will push the web 30 inwards to form a loop which partially encloses the spindle 6 and also presses the web against the knife 102 to cut the web; rubber rollers 113 and 114 carried by the levers 98-99 hold the web resiliently against the spindle 6. A glue roller 103 is driven from the cam-shaft 68 to apply glue to the extremity of the roll 28 which then rolls down the table 104 while the extremity is glued to the surface of the roll. The spindle 6 is then rotated slowly and the sequence of operations repeated. Instead of one winding spindle, two spindles may be supported coaxially opposite each other.

Abstract: 542,959. Coating surfaces; coated fabrics; compound fabrics ; cellulosic compositions. KODAK, Ltd. (Eastman Kodak Co.). May 1, 1940, No. 7830. Drawings to Specification. [Class 95] [Also in Groups IV and VIII] A process for coating surfaces consists of applying a layer of a cellulose ester having a melting point of not more than 230‹ C. and a charring point at least 40‹ C. above the melting point, and then heating the layer to such a temperature that it fuses on the surface being coated without becoming charred. The layer initially applied is preferably formed by coating the surface with a solution of the cellulose ester, and drying. The process is particularly applicable to the coating of the surfaces of metals, glass, wood, paper, fabric and leather, and to the coating of sheets of glass which are to be united by an intermediate cellulose ester lamina in the manufacture of safety glass. Specified esters are certain cellulose propionates, butyrates, acetatepropionates, acetate-butyrates, acetate-propionate-butyrates and propionate-butyrates, and these may contain also a proportion of higher acyl radicals, e.g. valeryl, caproyl, lauryl or stearyl. Pigments, dyestuffs, anti-oxidants, waxes and resins may be added to the cellulose esters, preferably in small amounts. Plasticizers are preferably absent, but may be added in small amounts. Specified plasticizers include diamyl and dibutyl phthalates, dibutyl sebacate, methyl, ethyl, butyl and methoxyethyl stearates, cetyl acetate, propionate and lactate, and esters of sugars with monobasic acids, e.g. sucrose octaacetate and octapropionate. An overcoating may be applied to the basic coating, e.g. by applying a solution of, or a molten, cellulose ester. This overcoating is preferably compatible with the initial coating, though one or more intermediate layers may be used, each being reasonably compatible with its adjacent layers. Examples are given.

Abstract: 711,996. Fluid-pressure servomotor-control systems; valves. BENDIX AVIATION CORPORATION. April 1, 1952 [April 7, 1951], No. 8293/52. Class 135 A control device for a fluid-pressure actuator comprises a spring-loaded plunger with a passageway therethrough affording communication between the pressure and working ports, a first valve spring-loaded to the position closing off communication between the working and reservoir ports, a tappet between this valve and a ball valve normally closing off the passageway through the plunger, and a condition-responsive device acting on that end of the plunger opposite the valves. In an embodiment, applicable to a system for actuating hinged flaps controlling the flow of cooling air through a radiator in the cooling system of an internal combustion engine, the valves comprise two balls 76, 96, spaced apart by a grooved pin 110, and controlling the flow of a hydraulic medium from an accumulator port 66 to a port 68 connected to a servo-cylinder, or from the port 68 to an exhaust or reservoir port 70. The temperature of the water jacket of the engine is detected by a thermal bulb and the resultant pressure produced in the thermal liquid is applied to the inside of a bellows 112. When pressure increases in the bellows, a rod 62 is moved to the left to abut against ball 76 so that the passage 78 through the rod connecting ports 66, 68 is shut off, and the continued movement of the rod will cause ball 96 to be pushed off its seat in a partition 84 in the casing of the device and allow the liquid in the servo-cylinder to exhaust from port 68 to port 70. The datum temperature is varied by adjusting the relative positions of a screwed sleeve 54 and a bushing 114.
