Abstract: ABSTRACT OF THE DISCLOSURE A multi-layer information recording medium for storing large amounts of information in a prescribed pattern of microscopic pits, formed by focusing onto the medium a beam of radiation having a prescribed wave-length and having an intensity modulated by the infor-mation to be recorded.  The record medium includes a substrate having a light-reflective surface on its upper side, a light-absorptive dielectric layer overlaying the substrata and having a thickness approximately equal to an odd integral multiple of one fourth the wavelength of the beam of radiation in the dielectric material, and a thin metallic layer overlaying the dielectric layer and having a light-reflective surface on its lower side. During recording of the information, a substantial propor-tion of the intensity-modulated beam of radiation is transmitted through the metallic layer to the dielectric layer where it is confined,due to multiple internal reflections by the light-reflective surfaces of the substrate and the metallic layer, until it is finally absorbed by the dielectric material.  This causes an evaporation of the dielectric material whenever the inten-sity of the beam exceeds a predetermined threshold, such evaporation carrying away the overlaying portions of the metallic layer and creating the prescribed pattern of microscopic information-bearing pits.

Abstract: ABSTRACT OF THE DISCLOSURE         When the slide gate of a hopper car is across the discharge opening and against the part of the frame that de-fines that opening, each of one pair of abutments below the gate and secured thereto is resting on a respective lever, which lever is generally vertical and secured to the rotatable shaft employed as a part of the mechanism for opening and closing of the gate.  At the opposite side of the discharge opening from the shaft, the gate has another pair of down-wardly facing abutments each of which then is resting on a respective generally vertical lever pivotally secured to the frame.  As the gate is initially moved horizontally away from that position the levers pivot to permit the gate to descend. In addition to forming the downwardly facing abutments, the parts that form those abutments also form abutments which engage the lever and pivot it to an upright position as the gate is being closed.

Abstract: TITLE: PRODUCTION OF METHANOL            ABSTRACT         In the production of methanol from a methane-containing gaseous feedstock such as natural gas by steam reforming the gas and treating the reformate to produce methanol by inter-reaction of the hydrogen and oxides of carbon in the reformate, the use of part of the feedstock to fire the reformer is avoided by immersing the reformer reactor tubes in a fluidised bed heated by the combustion of a low grade,solid, fossil-based fuel such as coal, lignite,oil shale or asphaltic residues from oil refining.  By pressurising the fluidised bed, all the power requirements of the process can be obtained by expansion of the flue gas, which can also provide the CO2 balance for the methanol synthesis, and a compressor can be omitted.

Abstract: ABSTRACT           An electrolysis cell is provided having an anode and cathode separated by an ion permeable membrane or dia-phragm wherein porous electrodes are pressed in direct con-tact with one or both sides of the membrane or diaphragm which porous electrodes are each comprised of or are associated with  a wrinkled resiliently compressible layer of an open metal fabric which presses the electrodes toward the membrane or diaphragm.  The fabric is substantially coextensive with the extent of the opposite electrode and/or the electrode active area of the diaphragm or membrane and is constructed so that when compressed, it exerts a substantially uniform elastic reaction pressure against the membrane over the major part or all of the area thereof opposite the counter electrode.  The cell may advantageoulsy comprise a pliable, foraminous, electroconductive fine mesh sheet, i.e. screen, interposed between the membrane and the resiliently compres-sible fabric which resiliently compressible fabric has the ability of also transmitting pressure laterally so that the applied pressure may be distributed across the entire active area of the membrane or diaphragm and the tendency to have local areas of too low or too high pressure is minimized or reduced.  Chlorine or other halogens may be produced by feeding an aqueous alkali metal halide or aqueous hydrogen halide into the anode chamber and alkali is produced in the cathode chamber and withdrawn.  The invention also includes an electrolysis cell, wherein at least one of the two electrodes is a resiliently compressible layer of an open mesh metal fabric, which is compressed against the diaphragm.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of treating biomass having fermentable material is provided utilizing acid hydrolysis in a countercurrent diffusion treatment structure.  By practicing the invention acid usage is minimized, pentose concentration in the hydrolysate solution is maximized, and ethanol can be produced without the input of any external energy whatsoever into the production method.  Biomass is particlized and slurried, and then is continuously subjected to acid hydrolysis at temperature, acid concentration, and residence time conditions sufficient to effect hydrolysis of the hemicellulose in the biomass to effect separation of pentose and hexose sugars into a hydrolysate having insufficient furfural to substan-tially inhibit fermentation microorganism growth, while not substantially hydrolyzing the cellulose in the biomass.  Fermentation of the pentose and hexose sugars in the hydrolysate may then be effected, and ethanol produced from the fermented pentose and hexose sugars utilizing conventional techniques.  Hydrolysis is practiced in an upright diffusion vessel with countercurrent flow, the acid concentration being about 2 to 10%, the temperature in the vessel being about 120°C or less, the residence time of the biomass in the vessel being about 1 to 3 hours, the biomass solids to liquid ratio being about 20/100 to 40/100 on a volume basis, and the particle size of the biomass being about 1-4 mm.
