Abstract: ABSTRACT A pull-top container comprises a preformed opening with sub-stantially paralled lateral edges in the container top, and a closure pro-vided with a grip and guided slidably along the lateral  edges of the opening. The closure is provided with an uninterrupted peripheral groove matching the shape of the preformed opening.  A stop is provided on the closure to limit its sliding travel on the container top.  The peripheral groove has a reduced depth in the area of the grip, as compared with the remaining periphery.  The margin al area of the preformed opening, adjacent the junction between the closure and the grip, is provided with scored lines that radiate from the periphery, and that are adapted to rupture to permit passage of the adjacent end of the closure when the container is to be opened.

Abstract: Abstract Disclosed is a system for precisely locating a cambered ceramic core within the cavity of an injection molding die, such as is used to form patterns for lost wax method casting of gas turbine airfoils.  A combina-tion of at least two independent sets of locators are used:  one set of at least three is fixed and contacts the periphery of the core while the other set of at least two is movable and engages the centerline of the core.  The two sets independently limit the various degrees of core freedom and maintain its position during injection molding.  The concave side of the core is pre-ferably contacted by the fixed locators since this biases deviations into the convex side of the part from which excess deviant material is more readily moved.

Abstract: ABSTRACT OF THE DISCLOSURE         The use of a flat perforated plate anode having openings of which the circumferential lengths in total are 3 m/dm2 or more in combination with a cation exchange mem-brane has been found to be extremely effective for rendering the current distribution in the cation exchange membrane uniform in practice of the ion exchange membrane process for the electrolysis of an aqueous solution of an alkali metal chloride so that not only elevation of the electrolytic voltage but also accelerated deterioration of the cation exchange membrane can be avoided.  Such use also has been found to have the effect that the voltage drop at the cation exchange membrane is decreased as compared with the case where an expanded metal anode is used.  Further, when the coating of the flat perforated plate anode on its front sur-face and the inner wall surfaces of the openings has a thick-ness larger than that of the coating on the back surface, the perforated plate anode has high durability and exhibits low electrolytic voltage for a long time as compared with the perforated plate anode which has, on each surface, a coating with the same thickness.

Abstract: ABSTRACT         A method and composition for non-destructive testing using the dye penetrant technique, and adapting the use of this technique at high temperatures.  The invention is involved with using a marking crayon which includes a carrier composed of a solid which melts at a temperature below the temperature at which the workpiece is to be inspected and a visible or fluorescent dye.          Upon application of the crayon to a hot workpiece, the solid penetrant composition becomes molten and the visible or fluorescent dye penetrates into any flaws in the surface in the usual manner.          A remover, also consisting of a crayon composition, is used to remove excess penetrant, leaving only penetrant entrapped in the flaws.  Upon removal of the excess penetrant and remover, the entrapped penetrant deposits are drawn to surface by the applica-tion of a finely divided developer either in dry form or as an aerosol.  Inspection of the piece is then carried out under visible or ultraviolet light, depending upon the nature of the penetrant.

Abstract: Liquid Fuel System Method and Apparatus Abstract A system is described for improving perform-ance of spark ignition, internal combustion engines using fuels such as liquified petroleum gas (LP-gas), which have conventionally been stored as a liquid and delivered to the engine as a vapor.  This system stores such fuels as liquids (10) and delivers the fuel to the engine inlet air stream as a liquid.  The absorption of heat by the vaporizing fuel lowers engine inlet air temperature, increasing its density and permitting more fuel to be burned in each cycle.  Vaporizing heat in a pilot line (17) provides the cooling to the liquid fuel in the main fuel line (20) and provides fuel to maintain the engine idling.  A member (27) slides within a fuel delivery chamber (25) for covering or uncovering a series of orifices (26) through which the liquid fuel passes into the inlet air stream of the engine.

A controllable circuit element is connected between the charge current source and the battery. This element is caused to modulate the charge curren in a manner so as to initially fast charge the sealed battery, but to limit its subsequent rise in temperature above the ambient to a predetermined small differential and to maintain that differential. This temperature rise limit brings about a reduction of charge rate as the battery approaches the full charge condition resulting in an acceptable current level for long term overcharge operation.

Abstract: IMPROVED STEAM STERILIZATION INDICATOR     ABSTRACT     A steam sterilization indicator comprising a tablet including a fusible material and an amount of binder, with a steam permeable membrane covering at least a part of the indicator.  The fusible material is meltable at and above a predetermined temperature in the presence of substantially saturated steam.  The melting point of the fusible material is substantially lower in the presence of saturated steam than when dry.          A wicking strip having one end in  close proximity to the tablet is provided whereby upon the attainment of the predetermined temperature, or above, the fusible material melts and moves along the strip at a rate proportional to the temperature of the saturated steam.          The binder holds the fusible material in tablet form prior to the attainment of the predetermined temperature or above and further provides a  mechanism for altering the rate movement of the fusible material along the strip as a function of the amount of binder used for certain temperature ranges, such rate of movement being similar to spore death kinetics.
