Abstract: A slide fastener slider is assembled from a stock of slider bodies, pull tabs and springs with apparatus which loads a body on an anvil at a loading station, moves the anvil to an assembly station and at the assembly station positions a pull tab to receive the lugs on the body therein, inserts a spring over the pull tab trunnion and between the lugs, the tip ends of the lugs thereafter being clenched to fixedly secure the spring to the body. The assembled slider is then ejected from the anvil to a collection point. In a further embodiment, the slider body instead of having lugs between which the spring is received and the tip ends of which are clenched to hold the spring, has lugs with recesses at the outer side surfaces thereof. The wing-like sides of the spring are inserted over the tip ends of such lugs with a spreading action until the spring sides snap into the recesses to secure the spring to the body.

Abstract: This invention relates to smoking articles, such as cigarettes, little cigars and the like, having a novel wrapper or outer covering and to a method for producing the same. More particularly, the invention relates to smoking articles comprising tobacco and a novel wrapper comprising a film having certain specified properties. The film preferably comprises a natural polysaccharide component which is preferably combined with an alkaline earth metal component. The wrapper possesses a unique appearance and other physical characteristics which are distinct from those of conventional wrappers for tobacco products, such as cigarette papers and tobacco leaves, as well as being distinct from the various modified tobacco products which have been taught as wrappers for smoking products.

Abstract: The spatial locations of points defining a specular surface are determined by disposing the specular surface in the field of view of a lens and by using the specular surface to view by reflection an irradiated reference surface disposed successively in different positions. Reference surface indicia viewed in common line of sight relation to each specular surface point in such different positions of the reference surface are identified. Radiant energy reflected by a specular surface point through the lens node and the location of the lens node defines a further line in space. The intersection of this further line and such line of sight defines the spatial location of such specular surface point. Photographic records made with the reference surface in such different positions contain representations of reflected radiant energy for all specular surface points in the field of view of the lens and in line of sight relation to the reference surface.

Abstract: Containers having top head openings are inserted axially without prealignment into a test chamber which houses a sealing member having a sealing surface radially continuous about the container insertion axis. The container interior and the extent of the test chamber encircling the container are commonly pressurized and the sealing device is displaced to seal the container openings. The encircling test chamber extent is then vented to atmospheric pressure and pressure change in the test chamber is monitored.

Abstract: A process for isolating a protein fraction from an aqueous solution or suspension containing the said fraction in admixture with other substances, which comprises subjecting the aqueous solution or suspension to ultrafiltration to obtain a retentate, diluting the retentate, subjecting the diluted retentate to at least one further ultrafiltration treatment and recovering a retentate containing the protein fraction.

Abstract: A heat exchange element for a rotary regenerative heat exchanger has corrugations of a wave-form conformation which include portions, extending between 10% and 50% of the wave length, which are parallel to the direction of flow of medium through the pack. Comparative data are given showing better efficiency in terms of heat-exchange effectiveness versus pressure loss than for apparently analogous prior art elements.

Abstract: A double action hammer for a revolver including a link pivotably mounted off center in a groove in the top of the hammer so that when pivoted from the groove to an exterior position relative to the groove it will be locked in place and will move the hammer to cock the trigger of the revolver for quick action. A leaf spring is embedded in the hammer between a wall of the groove and the bottom of the link to aid in pivoting the link to a closed position. In its closed position in the groove, the link has an outer surface contiguous with the outer edge of the hammer so that when the revolver is placed in a pocket, it will not snag on the clothes of the user enabling ready removal of the revolver.

Abstract: Stable cellulosic products containing releasable flavorant are described. These products are produced by impregnating a dry cellulosic substrate with an essentially anhydrous ammonia solution of a volatile flavorant and then subjecting the impregnated substrate to conditions of temperature and pressure sufficient to effect evaporation of essentially all of the impregnated solvent.

In one embodiment, a top octave generator operates responsively to an input signal having a characteristic which is variable in accordance with the relative positioning of visual display components of the apparatus. In a second embodiment a tone generator provides top octave and lower octave signals and selection is made for audible reproduction by a switching arrangement responsive to relative positioning of visual display components.

Abstract: A stationary-mass rotary regenerative air preheater uses a single regenerative mass for the separately controllable heating of different streams of air. This is achieved by providing at each axial end face of the mass rotating cowls divided into rotationally symmetrical hoods each of which is sub-divided into sector-shaped compartments which have the same radial extent as the mass. A given compartment of one hood on one end face is angularly of the same extent as the corresponding compartment of the other hood on that end face. The compartments are brought to coaxial connecting ducts at the neck of each cowl. Separation of media flows even under temperature or pressure differences is assured by sealing strips at each of the radially extending walls of each hood; these are automatically operated, and those on internal (sub-dividing) walls may be operatively linked to those on external walls.
