Title: Improvements in and relating to the production of catalysts
IPC: B01J23/90
Filed: 1921-05-09
Abstract: A catalyst for such reaction as the oxidation of ammonia, methyl alcohol, or methane, or for the preferential combustion of carbon monoxide in presence of hydrogen by reaction with steam, is prepared by heating silver or copper cyanamide, or a mixture of these, in the presence of air to the point where puffing occurs.  By incorporating a ferro- or ferricyanide, e.g. bismuth ferrocyanide, bismuth ferricyanide, calcium cerium ferrocyanide, cerium cobalt ferrocyanide, vanadium ferrocyanide, or molybdenum ferrocyanide, with the starting material, an activated product is obtained.  The silver and copper cyanamides are prepared by precipitating a dissolved cyanamide with silver nitrate and cupric chloride respectively; the calcium cerium ferrocyanide is obtained by adding calcium ferrocyanide to cerium chloride solution; and cerium cobalt ferrocyanide is prepared by the interaction of cerium chloride, potassium ferrocyanide, and a soluble cobalt salt.ALSO:A catalyst for the oxidation of methyl alcohol or methane to formaldehyde is prepared by heating silver or copper cyanamide, or a mixture of them, in the presence of air to the point where puffing occurs.

Title: Improvements in or relating to the distillation of coal
IPC: C10B7/02
Filed: 1930-04-30
Abstract: 348,361. Carbonizing apparatus; charging and discharging retorts. PUENING, F., Koppers Building, Pittsburg, U.S.A. April 30, 1930, No. 13278. Convention date, April 30, 1929. Addition to 312,238, [Class 55 (i), Coking &c.]. [Classes 51 (ii) and 55 (i).] In a coking apparatus comprising annular concentric chambers formed by walls suspended from head plates, as described in the parent Specification, a gastight separating wall or head plate is provided between the coking chamber and the heating gas conduits, the plate having folds to permit of expansion. The fuel chambers are charged from above, and the charge is levelled by a displacing bar, and may be compacted by a stamping device. The head plate 1 is in sections 1<1> having flanges 3, which may be bolted together, and has folds 4, 5, to give resilience, a layer 6 of firebrick resting on the plate 1. The heating gas flows from a duct 8, Fig. 4, down into the heating chambers 9 in which it is spread by guide-plates 10, and then through tubes 11 into an outlet duct 12, the inlet duct decreasing and the outlet duct increasing in section. To prevent one wall element springing against the other, the elements 2 have projections held by a locking plate 15 mounted on a base 16. The fuel chambers 26 are charged by a thrower 21 having a mouthpiece 24, a valve 33 cutting off the fuel supply when the conduit 24 does not register with a space 25. Excess coal is returned by an elevator 35 to the fuel pipe 31. A displacing bar 37 carried by a rotating mounting 40 extends along the upper part of each fuel chamber, and has an opening 38 through which the fuel enters. When a surplus of fuel has been supplied, this bar is retracted, and its place occupied by the fuel, so that a constant level is maintained, and a space 25 left, into which the distillates pass on their way to the outlet 68. A hand- or machineoperated scraper 44 removes small accumulations of coal, and a guard 48 on the bar 37 prevents coal being thrown past the last fuel chamber. A stamping device comprising an oscillating arm 50 having fingers 51, causes the coal to settle to a greater density than usual. The forward end 59 of the arm 40 discharges the coke from chamber 26<111>, the flap doors 57 having been dropped.

Abstract: 143,719. Hargreaves, J. May 29, 1919. Mules and twiners.-In a nosing-motion for a mule &c., the winding-on chain is attached to a cam or like member pivoted to the quadrant arm and connected by a chain or cord to a member adapted, at the end of the inward run, to exert a pull on the chain &c. and to rock the cam &c. about its pivot, to exert an additional pull on the chain and accelerate the spindles. The winding- chain e is secured to one part a<1> of a double cam a. The other part a<2> has attached to it a cord g which passes over pulleys g<1>, g<2> and is secured to a ratchet-toothed rack f sliding in a guide h.. A pawl j pivoted to the carriage is adapted to engage the rack and move it at the end of the inward run. The time of engagement of the pawl with the rack is regulated by a slide l working in conjunction with the copping-plates. A pin p on the pawl moves over the slide. The parts are returned to their original position by the rewinding of the chain on the winding-drum. The cord g may be attached to a slide adapted to be engaged and moved by a nut on a screw in the carriage. The position of the nut on the screw is regulated during the building of the cop by a ratchet-feed operated each time the carriage approaches the quadrant. The cord g may be attached directly to the nut and lie slack during the outward and the major part of the inward run. According to the Provisional Specification, the winding-on chain is wrapped round both portions of the cam, and is attached to the sliding rack, a separate cord g being dispensed with.

Title: Stack stabilizer for papaer stacking machine
IPC: B65H29/18
Filed: 1974-03-28
Abstract: 1462811 Sheet stacking apparatus GRAPHIC ENGS Inc 28 March 1974 [29 March 1973] 13752/74 Heading B8R Sheet stacking apparatus comprises conveyer belts 14 arranged to transport an overlapping stream of sheets up to a retractable stop 22 to build up a stack from the bottom and a pressure wheel 28 arranged to press relatively lightly on the stack until the last few sheets are to be added and then to press relatively heavily on the stack during the addition of these last few sheets and during the retraction of the stop. This prevents slippage as the stack is accelerated away from the stacking location by the belts 14. The wheel is carried on an arm 30 pivoted at 32 to a slotted arm 34. The arm 34 is pivoted at 36 and is biased downwardly towards a rest stop 48 by coil torsion springs around shaft 36. A lost motion device 70 comprising an elongated loop is attached to the end of arm 30 beyond the pivot point 32. The loop encircles arm 34. During stacking the arm 30 is free to move relative to arm 34 until the top of the loop engages the arm 34 whereupon arm 34 is raised against the spring bias. There may be a plurality of wheels 28 and arms are 30 and 34 spaced laterally across the stack. The pivot 32 may be adjustable along slot 58. The lower surface of the loop may act as a stop to prevent arm 30 falling too far when the stack is removed, thus preventing wheel 28 from engaging the conveyer belts 14. Air blast from a nozzle 26 helps to guide the sheets into stacked position and relieves the weight of the stack on the bottom sheet.
