Abstract: Abstract of the Disclosure A machine for stiffening and forming a selected area of flexible sheet material, for instance an end portion of a shoe upper, comprises work support mechanism including a universal female preformer having work-accommodating dihedral surfaces, an applicator for depositing on a portion of the selected area a predetermined volume of molten resin substantially in proportion to that area, and a presser complemental to the cavity defined by said surfaces and relatively movable into and out of cooperative work-pressing relation with respect to the work support to spread the molten resin and impart appropriate thickness gradient thereto throughout the selected area whereby, upon cooling, it is formed three-dimensionally and stiffened a desired degree in different portions.           For forming in-place end portions subsequently to be lasted, such as backparts of shoe uppers, pincers suitably  control spreading and tensioning of the work and then relatively move with respect to the applicator to partially distribute the resin extruded in parallel arrangement within the area prior to shut-off of resin flow directed at an angle on the order of about 45° to the area.  Thereupon, the applicator being retracted, the molten resin is fully distributed throughout the selected area by mechanism closing the dihedral surfaces normal to the adjacent presser thus avoiding wrinkling and/or scuffing of the shoe upper and disturbing the distribution, in thickness and laterally, of the still molten resin.

Abstract: IMPROVED HIGH PRESSURE PROCESS FOR PREPARING DIAMOND WIRE DIE COMPACTS             ABSTRACT OF THE DISCLOSURE A process improvement is disclosed for making diamond wire die compacts of the type which are generally described as an inner polycrystalline diamond mass surrounded by and bonded to a mass of metal bonded carbide, such as cobalt cemented tungsten carbide.  It is known to make these dies by high pressure-high temperature processes, typical conditions being 50 kbar and temperatures in excess of 1300°C.  The improvement comprises disposing within the reaction sub-assembly (e.g. metal carbide and diamond within a zirconium cup) a set of discs of specific materials of a specific thickness range and in specified arrangements.  On one side of the mass of metal carbide and diamond is disposed one disc of a diamond catalyst/solvent and one disc of a refractory metal such as molybdenum, and on the other side are disposed at least two discs of one or more transition metals such as zirconium.  These discs are generally placed inside the sub-assembly cup and have a thickness range of 25-102 microns.  By means of this process modification, process yields have been significantly improved through decreasing the occurrence of defects in the dies and by decreasing the reaction time.

Abstract: A B S T R A C T          A method of enhancing the naturally developed colour of an anodic oxidation coat chemically produced on an Al alloy in which the coat is formed by electrolysis employing a warmed electrolyte of sulphuric acid and an alternating current the polarity of which is periodically reversed to be negative for a period of 10-20% of each cycle while being applied to the Al alloy dipped in the electrolyte as an anode for 20 to 40 minutes.  The thus coated Al alloy is subjected to a heat treatment in a boiling sealing liquid for 20 minutes.  During each negative polarity period of the current, electrolytic reduction takes place on the Al alloy (which is acting as a cathode), whereby sulphur in the electrolyte reacts with the added alloy element of the Al alloy to form a sulphide of the alloy element.  The alloy metal sulphide thus formed is accumulated in the coat and, during the heat treatment, the alloy metal sulphide accumulated is further combined with the alloy element in the form of metallic ion to further develop the colour of the coat.

Abstract: ABSTRACT OF THE DISCLOSURE The invention provides a multiple coin detecting apparatus for use in coin-operated machines for discrimin-ating between denominations of coins and genuiness of coins, so as to exclude from operation of the machines any coins which have not been specifically selected for acceptance. Essentially, the apparatus consists of a coin receiving and guiding free-fall chute of insulating material having a hollow core for receiving coins. An instantaneous analysis is made of the material of the coin near the entry of the chute and the apparatus im-mediately directs predetermined acceptable coins to an acceptance slot, and all other unacceptable coins are directed to the rejection slot. The analysis is made by a coil which surrounds the hollow chute and comprises a primary coil and a secondary coil. The secondary coil has windings protruding a specified distance over the edges of the primary coil and at a predetermined angle in relation to the windings of the primary coil, and provides a secondary coil voltage fluctuation in con-junction with the primary coil voltage fluctuation, to give separate indications of the exact metal contents of the coins being evaluated. These two independent voltages are each connected to a chain of comparator gates whose outputs are subsequently rendered high in direct proportion to the magnitude of voltage appearing at their input, forming a direct analog to a digital converter. Selective acceptance of each coin is therefore possible by decoding its exclusive digital code.

Abstract: Electromagnetic Fuel Injector with Improved Discharge Structure Abstract An electromagnetically actuated fuel injector is provided with a discharge region of improved con-struction.  The injector discharge region includes a central flow axis and, sequentially in the down-stream direction, a simple metering orifice symmetri-cal with the axis, and flow patterning structure in-cluding a diverging flow director for directing the flow of fuel issuing from the metering orifice ra-dially outward relative to the axis to an annular region about the axis and a converging flow director for directing the fuel radially inward relative to the axis from a position radially outward thereof for direct "transparent" discharge thereafter from the injector.  A discrete exit nozzle may be shaped to effect the requisite flow convergence, and the angle of that convergence affects the geometry of the final spray pattern.  A swirl disc may be positioned intermediate the other two flow directors.  By pre-selecting the angle at which channels in the swirl disc are skewed to the axis, it is possible to obtain respective ones of a variety of fuel spray patterns ranging from a wide angle hollow cone for an acute angle of tangentiality to a string of fuel droplets substantially along the axis when the swirl channels are substantially parallel  the axis.  The upper and lower ends of the swirl disc may be tapered.
