Abstract: An apparatus includes a tool body including first and second overlapping body members that are joined together by a first linear slide establishing a first coordinate axis, wherein the first body member has a first planar region that is perpendicular to the first coordinate axis and faces away from the second body member, and wherein the second body member has a second planar region that is perpendicular to the first coordinate axis and faces away from the first body member. The apparatus further includes a latch secured to the first body member and selectively engageable with the second body member to prevent relative movement of the body members along the first coordinate axis. The apparatus also includes planar elongate arms having a distal end forming a hook, the elongate arms being selectively securable to the planar regions at a plurality of positions along a length of the elongate arms.

Abstract: A workpiece deflector shield includes a flexible web arranged for extension and retraction relative to separable mold halves that are arranged in operative relationship relative to one another from a first engaged positioned to a second spaced relationship, wherein in the spaced relationship, the flexible shield structure provides for deflection of a workpiece ejected from the separated mold members.

Abstract: A new drug delivery system, which gives sustained release properties is made by combining certain cellulosic polymers with cellulose in a binder system.

Abstract: Drug delivery systems which exhibit sustained release properties when administered are produced using a "dual control" system which employs polymeric agents in core and membrane portions.

Abstract: A unique sustained release dosage form which prevents the tendency of an initial surge of medicament in the first hour of administration. The control is by a porous membrane coating. The amount of initial release can be varied by varying the proportions of the components of the coatings.

Abstract: A pressure fluid operated impact type tool having cyclic pressure fluid operation of a reciprocable hammer piston, and for which there is provided accumulator means connected directly to pressure fluid supply and/or return of the tool.

Abstract: A mining machine having a mineral winning head mount including a plurality of links pivotted successively one to another and powered means for pivotting the successive links about their pivot axes and whereon said links and powered means allow the mineral winning head to be retracted at least partially into an angled configuration of the links.
