Abstract: CUT-OFF PROTECTION SYSTEM      FOR ELECTRICAL DISCHARGE MACHINING APPARATUS         Abstract A programmable system for controlling machining current magnitude and reducing it in a step function as gap voltage (10) falls indicating gap short circuit condition. A set of off-time numbers are computed and stored in an off-time counter. These numbers are recomputed each time a new on or off time is entered in the pulse generator (18). The original off time is the normal cutting parameter. As the gap voltage drops, indicating problems, the off-time starts doubling or increasing in a like manner until it has reached many times its normal duration.

Abstract: Method for Making a Shear Blade Abstract A shear blade assembly on, for example, a tree harvester has first and second blade portions which are urged into opposite portions of a tree circumference to cut the tree.  A desirable shape of the blade assembly is a concave configuration which minimizes tree damage and efficiently distributes loads through the shear blade assembly.  An improved method for making the con-cave shear blade assembly includes cutting blade surfaces on a blank and leaving a web between the sur-faces, then depressing the blank to form the desired shape and dividing the blank along the web to form the first and second blade portions.  Making the surfaces before shaping and dividing the blade portions over-comes problems stemming from distortion of blades which are cut along a curvature following the step of obtaining the desired shape in the blade assembly.

Abstract: ABSTRACT      A process for recovery of platinum group metals (PGMs) from refractory ceramic substrates containing an aluminium silicate and/ or alumina, for example, wash-coated auto emission control catalysts and Pt reforming catalysts.  A charge, in divided form, containing the substrate, one or fluxes and a collector is heated in a high heat intensity furnace, to a temperature of at least 1420°C to produce a molten metallic phase including a substantial proportion of the said metals and a molten slag phase.  These are then separated and the platinum group metals subsequently extracted from the metallic phase.  By choice of suitable fluxes, at least some alumina can be converted to an aluminium silicate which becomes molten at the operating temperature.  Further, the ability to use high temperature fluxes avoids the need for an excessive slag which is normally required to dissolve the high alumina content of such catalysts and which normally gives rise to unacceptable losses of the metals to be recovered when applying conventional pyro-metallurgical techniques.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention provides a novel and very economical method for the industrial production of ethyleneglycol starting with formaldehyde and synthesis gas, i.e. a gaseous mixture of carbon monoxide and hydrogen.  The method utilizes the synthetic route in which a formaldehyde di-sec-alkyl acetal, which is obtained from formaldehyde and a sec-alcohol, with carbon monoxide and hydrogen to form an ethyleneglycol mono-sec-alkyl ether which is then hydrolyzed with water into the desired ethyleneglycol.   The first step reaction of the acetal compound is catalyzed with a single component catalyst of cobalt carbonyl while the hydrolysis reaction proceeds with an acidic catalyst in a high yield unexpected from the similar reaction of ethyleneglycol mono-primary-alkyl-ethers.

Abstract: ABSTRACT   An electro-optical measuring system in a photogrammetric comparator or stereocompiler comprises a visible light transparent phase grating which is carried upon a surface of the photo support plate of the device. The grating is formed as a composite layer of .lambda./4 films of at least two dielectric materials of different refractive index which are deposited on the support in such a manner as to yield parallel bands in which the two film materials are in alter-nating sequence from band to band. As a result of this structure which ensures a constant physical and optical thickness with respect to transmitted imaging light over the whole grating pattern, image-degrading diffraction of the trans-mitted visible light is avoided, yet the grating pattern provides interfering diffraction in reflection which may be utilized in a precise displacement measuring system.
