Title: Improvements in or relating to refractory articles of bonded granular silicon carbide
Inventor: WASHBURN MALCOLM EDWARD
Filed: 1961-07-21
Abstract: In the manufacture of refractory articles comprising at least 65% by weight of a refractory granular silicon carbide material, temperature resistant to at least 1200  DEG C., joined into a unitary article by a silicon nitride bond, a mixture of silicon carbide material, finely divided silicon and a finely divided cyanamide compound, in which the available silicon and available nitrogen in combined form are present in a weight ratio of at least two parts silicon to one part nitrogen, is formed into the shape of the article and fired at a temperature above the decomposition temperature of the cyanamide compound.  The firing may be carried out in electric kilns or fuel-fed periodic or tunnel kilns. Preferably the silicon carbide and bond ingredients are fired in an oxidizing atmosphere at a temperature of from 1200-1500 DEG C. after first being subjected to high pressure, for example 3 tons per square inch, and the rate of firing is controlled to provide a product having a silicon nitride bond at least a portion of which is an oxynitride of silicon having an X-ray pattern with d values of 4.67<\>rA and 4.44<\>rA.  In the mixture, which preferably contains at least 65% by weight of silicon carbide material, the cyanamide compound may be calcium cyanamide or dicyandiamide; other cyanamide compounds which may be used include cyanamide, cyanurotriamide (melamine), sodium cyanamide and lead cyanamide. In the refractory article, the ratio of free silicon to nitrogen is preferably between 1.8 and 10, and the nitrogen content of the bond, which is the reaction product formed upon firing a mixture of particles of silicon and particles of a cyanamide compound at a temperature above the decomposition temperature of the latter, may be higher at the centre of the article than at the surface thereof.  The mixture may also contain small proportions of dextrine, methyl cellulose or other organic temporary binder, powdered bentonite or other plasticizing agent, and water for moistening.  The article is said to be resistant to molten cryolite and may be used for cell linings in aluminium extraction processes.

Title: An improved compound enforced asphalt
IPC: E01C5/12
Filed: 1934-05-22
Abstract: A process for the production of road-making and like compositions of the type comprising a mixture of spent shale with pitch, tar, oil or bitumen is characterized by adding the granulated spent shale to the hot liquid pitch, &c. while mixing slowly and raising the temperature gradually to boiling-e.g. to about 370 DEG  F.-until the pitch, &c. will take up no more shale. The proportion of pitch, &c. in the final mass may be from 5 to 25 per cent.  The mass is then poured into metal moulds and cooled quickly.  The resulting blocks may be used for laying roads or streets, being placed together edge on, the sides being heated with a blowlamp and the blocks thus welded together into a solid mass.

Title: Improvements in or relating to speed governing mechanism
IPC: G05D13/00
Filed: 1930-09-10
Abstract: 351,333. Speed governors ; extraction turbines. WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.-(Assignees of Flanders, W. B. ; 6043, Ellsworth Street, Philadelphia, U.S.A.) Sept. 10, 1930, No. 27004. Convention date, Oct. 4, 1929. [Classes 57 and 110 (iii).] A fluid governor in which fluid pressure from a pump driven by the prime mover acts upon a pressure-responsive device wherein additional fluid pressure, acting in opposition to the governing fluid upon the responsive device, and increasing with increased opening of the throttle valve and decreasing with decreased opening of the throttle valve. The application to an extraction turbine is described. The pressure responsive device 39 is arranged within the power piston 41 fitted in a cylinder 44. The device 39 is arranged with ports 54 to pass fluid pressure through ports 48 to the top of the piston 41 and with recesses 55 for connecting ports 48 to ports 49 allowing exhaust to port 51. The fluid pressure on the device 39 acts against the tension spring 57 attached to a member 58 connected by a follow-up arrangement of links to an extension 46 of the power piston 41. The top 56 of the device 39 is arranged with a small orifice 67 connecting through the chamber 66, port 69 to a spring-loaded valve 71. A weight 72, provided with a dashpot 77, rests upon the spring 73 and is partly supported by a spring 74 connected to an arm 75 attached to the extension 46. The movement of the power piston thus varies the loading on the valve 71, consequently varying the pressure in chamber 66. The device acts so that upon the prime-mover departing from its normal speed, the governor tends to close the throttle valve, causing an increase in pressure in the chamber 66 which slowly returns the device 39 to a position causing further closure of the throttle valve and returning the prime mover to its normal speed. By choosing the scale of the spring 74, the governing range may be reduced, or eliminated as described above, or made negative, i.e. speed increasing as the load increases. The Specification as open to inspection under Sect. 91 (3) (a) comprises also means responsive to pressure in the extraction conduit for operating the extraction valve 13. A pipe 33<1> connects one side of a spring-controlled diaphragm 33 to the extraction conduit 14. The lever 31 is connected in the usual manner to the pilot valve 25 and power piston 16 operating the extraction valve. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,194,253. Electro-photographic materials used for producing printing plates. RANK XEROX Ltd. June 13, 1967 [June 15, 1966], No. 27307/67. Heading G2H. An electro-photographic process comprises imagewise exposing a material consisting of a support bearing a right-reading image on one side and a charged photo-conductive layer on the other to produce a latent electrostatic image which is developed with electroscopic particles and fixed to produce an image complementary to the rightreading image. This image may be built into a relief image by repeating the above steps and then either fixing the developed image and inking it to produce a relief printing plate or not fixing but transferring the image to a support. Alternatively, if the support is hydrophilic acid the particles hydrophilic, this laterally reversed image may be used as a lithographic printing plate without building up the image. In the examples, a polyester support has a right-reading image xerographically transferred thereto and the other side is coated with a selenium layer which is uniformly charged. The material is exposed through the image to produce a latent image on the selenium layer. This latent image is developed with polystyrene toner and fixed. The material is now recharged in the presence of light so that the charge is retained in the non-conductive image areas, redeveloped and fixed to produce a relief image for use in letterpress printing. Alternatively the image is not fixed but transferred by adhesive contact to an adhesive receptor sheet.
