Title: Gasification of solid carbonaceous  materials
Inventor: TANOUE TOYOSUKE
IPC: C10J3/46
Filed: 1979-12-27
Granted: 1983-08-16
Abstract: Abstract This invention relates to a method of and apparatus for the gasification of powdered carbonaceous materials e.g. coal, coke, pitch or coal tar, wherein a hot spot is formed on a bath of molten iron by blowing a group of oxygen-containing jets onto the surface of the iron, and the powdered carbonaceous material with carrier gas is simultaneously blown onto the hot spot.  By the practice of the invention the efficiency of gasification is increased over previously-known methods of gasification, and impurities particularly CO2 in the produced gas may significantly be reduced.

Abstract: ABSTRACT OF THE DISCLOSURE     A system which processes menus on which food items have been selected.  The menu is encoded to have a plurality of detecting paths, with a first transverse row of preassigned markings in selected areas of the paths.  Additionally, there are provided uniform indicated spaces arranged in a subsequent transverse row on the menu.  Each indicating space is associated with a respective food item.  The user selectively places marks in the indicating spaces indicating desired food items.  The system detects the preassigned markings in the first row and in reponse thereto initializes circuitry to register information identifying the menu, specifically the menu diet and meal.  The system then detects the additional markings placed in the indi-cating spaces, and a recording circuit responds to these additional markings to record a count for each food item selected for that particular identified menu diet.  The system then tallies the total count for each food item of all the different types of menus.

Abstract: A B S T R A C T      The present invention relates to a method wherein solid organic material, originating from plants or animals or both, is converted by an anaerobic fermentation, that is less labour, time and space consuming than the conventional aerobic fermentation method, and may be performed with an organic material that has not to be subjected to a pre-treatment wherein a slurry having a rather low solids content is prepared. According to the present method a solid organic material originating from plants or animals or both is subjected to a treatment that consists of at least 2 steps, in the first step of which, that is performed under known anaerobic conditions in at least one primary reactor, a break down to water soluble product and low molecular weight fatty acids occurs, while in the next step(s) under anaerobic conditions methane is generated from said organic compounds. The water soluble fatty acids and other water soluble organic and inorganic materials that have been generated in the first step of the reaction, in a reaction space, are removed by rinsing with an aqueous liquid and fed to at least one auxiliary reactor while the water insoluble materials that are still present in the reaction space are left in said reaction space, while in said auxiliary reactor the organic material of said aqueous solution is converted into a mixture of carbon dioxide and methane, and subsequently the residue formed in said reaction space, that has the properties of a stabilized compost, is removed therefrom.

Abstract: A B S T R A C T          A retaining wall is constructed from concrete slabs laid in horizontal courses, in half-lapped relationship.  The slabs are of uniform length and thickness, but of differing widths.  The bottom, middle, and top thirds (approximately) of the wall are constructed respectively of relatively wide slabs, of slabs of intermediate width, and of relatively narrow slabs.  A course of extra-wide anchoring slabs is provided about half-way up the wall.  The front face of the wall defines a substantially planar surface, while the rear face of the wall is stepped, and the extra width of the anchoring slabs projects from the rear face of the wall.  The slabs are provided with apertures, so arranged as to be in alignment when the slabs are assembled into a wall structure, forming continuous apertures extending from top to bottom of the wall.  Dowell rods of metal or other suitable material, are disposed in these continuous apertures; the rods are of such dimensions as to fit inside the apertures with appreciable clearance.  The completed structure is fully interlocked, since all structural slabs are locked into this structure by the dowell rods, and the structure is sufficiently flexible to be capable of substantial deformation, in response to land subsidence, frost heaving, thermal expansion and contraction, and the like, without breakage of structural elements, or loss of structural integrity.

Abstract: ABSTRACT             A raster output scanner having a movable imaging member and high intensity imaging beam for exposing the imaging member to create images thereon. A rotating polygon scans the beam across the imaging member in line by line fashion while a modulator astride the beam path modulates the beam in accordance with image signals or pixels input thereto. A clock provides clock pulses for clocking the image pixels to the modulator. To assure uniform image size despite variations in the velocity of the imaging member, a control signal representative of imaging member velocity is used to control polygon velocity and maintain a predetermined velocity relationship between imaging member and polygon. Means are provided to servo clock frequency with polygon rotation, with a control to shift the clock servo midpoint frequency in response to changes in imaging member velocity.
