Abstract: OUTLET BOX FASTENER                   Abstract of the Disclosure A fastener for securing an electrical switch or outlet box in an opening in a wallboard or similar wall surface.  The fastener can be formed, for example, of metal and includes a first surface adapted to be positioned flush against the interior surface of the wallboard, a second surface which extends rearward-ly from the wallboard substantially perpendicular to the first surface and which is adapted to be positioned against one side of the outlet box, and one or more fingers which initially are substantially coplanar with the first surface and so are adapted initially to extend parallel to the wallboard, into the opening of the wallboard in which the outlet box is fitted.  The fingers are bent outwardly around the side edge of the wallboard created by the outlet box opening.  A fastener is positioned at one, and preferably at each, side of the outlet box opening, and the outlet box is inserted into the opening.  The fingers of each fastener are then bent over the front edge of the outlet box to lie against the interior of the outlet box side surface.  The outlet box is thus retained in the opening by the cooperation of the fasteners first surfaces, which abut the wallboard interior surface, and flanges which conventionally extend vertically from the outlet box top and bottom surfaces and which thus abut the wallboard exterior surface.

Abstract: : Procédé de traitement en continu d'une matière cellulosique en copeaux par passage de copeaux dans une machine comprenant deux vis parallèles à filetages identiques entrainées en rotation dans le même sens à l'intérieur d'un fourreau les enveloppant et dont les filetages comportent des zones sucessives à pas différents.  Selon ce procédé, on fait passer la matière en continu dans une première zone d'alimentation et d'entrainement vers l'aval suivie d'une première zone de freinage provoquant une première compression de la matière, puis dans une seconde zone d'entrainement vers l'aval avec mise au contact d'n réactif introduit dans le fourreau, suivie d'une seconde zone de freinage provoquant une seconde compression de la matière.  Lors de chaque compression, la matière passe par une série de phases alternées de montée en pression dont l'importance relative augmente progressivement et de chute de pression dont l'inportance relative diminue progressivement, et le passage des copeaux dans chaque zone de freinage provoque un simple fractionnement des copeaux susceptibles de favoriser leur tassement dans les filets sans diminuer la longueur des fibres.  La première compression provoque l'expulsion vers l'amont de l'eau contenue dans la matière et chaque compression suivante provoque l'expulsion du réactif usé et des liqueurs résiduelles contenues dans la matière, l'ensemble du traitement provoquant une délignification au moins partielle des copeaux sans véritable défibrage mécanique.

Abstract: ABSTRACT OF THE DISCLOSURE       Crumbled cheese curd is fed into the top of a hollow perforated column in a chamber maintained at a sub-atmospheric pressure so as to form in the column a pillar of curd devoid of air pockets, the curd in the lower portion of the pillar being compressed by the weight of superimposed curd to press out whey therefrom and consolidate the curd, the whey passing through the perforations in the wall of the column, and the pillar of curd is repeatedly lowered, the bottom end of the pillar severed to form a block of cheese, and fresh curd added to the top of the pillar.  During the lowering of the pillar of curd, the gaseous pressure in the space between the column and the wall of the chamber is increased so as to effect a transverse compression of the pillar of curd and thereby reduce the frictional sliding resistance between the pillar of curd and the column.

Abstract: ABSTRACT OF THE DISCLOSURE         A lockable slider fastener of the type including locking mechanism having a drum rotatable about an axis generally perpendicular to the plane defined by the Y-configuration of the slider channels for passage of fastener elements.  One face of the cylindric drum defines a cam surface for actuating one end of a locking lever whose opposite end forms a locking bolt element for engagement with slider elements to lock the fastener, the drum being urged away from the plane of the "Y" by an axial spring.  Contrary to prior art slider wherein the drum engages the locking lever only such as to move same out of locked position, while the elements engaging movement is effected by a separate spring, the invention couples the cam drum engaging end of the lever to the axial spring such that the axial spring is utilized both in urging the drum and the lever into its locked position, either directly or with the drum as an intermediate.  The invention simplifies the structure and provides for a slimmer, more elegant overall configuration of the slider.

Abstract: Mounting Device Abstract A mounting device for anchoring a machine element coaxially on a rotary shaft.  The device fits between the machine element and the shaft and is effective to position the element at any desired position longitudinally of the shaft and at any angular position circumferentially of the shaft.  The device has similarly tapered inner and outer segmented sleeves, so that relative axial displacement of the sleeves effects radial expan-sion and contraction of the combined elements.  At one end the inner sleeve cooperates with a nut to effect the axial displacement of the sleeves.  The outer sleeve has separate segments coupled with said nut to permit limited pivotal move-ment of the segments.  In another embodiment, the sleeves are constructed to avoid relative rotation between the sleeves by a locking portion.  In a third embodiment, the inner sleeve also has separable segments and a tubular element which are interconnected similarly to the interlocking of the outer sleeve segments with the nut.  Improved performance is provided by providing anti friction bearing elements between the nut and the outer sleeve and anti-friction screw threads between the nut and the inner sleeve.  Alternatively, an anti-friction coating may be applied to the nut.

Abstract: ABSTRACT OF THE DISCLOSURE          A continuous process of contacting crude oils, particularly triglyceride oils, with an acid for the purpose of removing phosphatides and trace metals is disclosed. The acid is introduced into a stream of heated oil imme-diately ahead of mixing means, such as a static-mixer, capable of achieving an acid droplet size smaller than 10 microns in diameter.  The interfacial surface provided by these microscopic droplets allows the acid-oil contacting process to occur essentially instantaneously, requiring less acid and less acid-oil residence-time. The process is useful in treating crude oils prior to alkali-refining or prior to a bleaching treatment in preparation for steam-refining.
