Abstract: SPECTACLE FRAME FOR MULTIFOCAL LENSES     Abstract of the Disclosure:      A frame for multifocal spectacles in which a side piece is attached to each of a pair of lens rims through a hinge mechanism which permits downward rotation of said side piece relative to said rim through a prescribed angle, and a nosepad is mounted on each of the lens rims through a level adjusting mechanism by which the nosepad is vertically moved causing the level of said lens rims to be altered in correspondence to the change of inclination of said side piece.      By means of the hinge mechanism, through a simple operation, each lens segment of the multifocal lens can be used at the optimum angle with respect to the line of vision, and by means of the level adjusting mechanism for moving the nosepad vertically, each lens segment is moved vertically to the level most suitable relative to the line of vision and at the same time neatness of appearance and decrease of fatigue are obtained whichever pair of lens segments is used.

Abstract: ABSTRACT OF THE DISCLOSURE      An improved drag string unit is shown for use with well bore drill stem test tools of the type which have an inflatable packer and an integral pump.  The drag spring unit has an outer drag spring housing and an inner man-drel slidably received within the drag spring housing.          Ratchet surfaces associated with the outer housing and inner mandrel are positionable between an engaged posi-tion which allows the pump to be activated to pump up the packers and a disengaged position which prevents activation of the pump.  Vent means are alignable be tween the inner mandrel and outer housing when the rat-chet surfaces are disengaged allowing the packers to vent to the well bore.

Abstract: ABSTRACT           The invention is concerned with a method of manufacturing a composite refractory article having a flow passage through which a molten metal stream may be conducted and comprising a first body of refrac-tory material which defines a surface of that passage, the first body being bonded to a second body of re-fractory material.  The method of the invention is characterized in that the second body defines a passage-way of greater cross-sectional dimensions than the flow passage and that the first body of refractory material is provided within such passageway for defining the flow passage surface, the first body being formed in the larger passageway by causing its refractory material to cohere and bond to the second body by fusion or partial fusion in situ.  The composite refractory article thus obtained has the first body located within a passageway formed in the second body, such passageway being of greater cross-sectional dimensions than the flow passage so that the first body coheres and bonds to the second body by fusion or partial fusion of those bodies at least at their joint.  The first re-fractory body may be composed of fused or partially fused refractory material and it may be a relatively high grade refractory body while the second body is a lower grade refractory body.

Abstract: A seal for use around a rod electrode passing along an axis through a hole in the wall of a furnace into the interior of the furnace has an annular and at least limitedly flexible seal ring fitted snugly around the electrode in the hole and a holder carrying the seal ring and sealingly engaged with the furnace wall. Thus gas flow through the wall at the hole past the seal ring is substantially blocked. The seal assembly has structure forming with the electrode and seal ring a substantially closed chamber surrounding the electrode axially inward into the furnace from the ring. This chamber is pressurized at superatmospheric pressure with an inert gas and the electrode is cooled inward of the furnace from the seal ring. The seal ring is compressed axially by a packing assembly so it is pressed radially against the electrode. The packing includes rigid split compression rings bearing axially on the seal ring.

Abstract: Stock Feeder With Adjustable Width Feed Path Abstract A stock feeder for repetitively feeding uniform segments of a continuous web of stock material from a roll to a production machine.  The feeder comprises a frame, a pair of hold clamps located on the front portion of the frame, and a movable feed block which carries a pair of feed clamps that grips and pulls the stock material to a position which is held by the hold clamps.  To obviate the necessity to reposition the clamps when changing the width of stock material, the frame includes first and second pairs of laterally adjustable stock roller guides located, respectively, on its front and rear portions.  Also, to enable the feeder to operate faster without destruction or dete-rioration, and yet still attain good positioning accuracy of the stock material, the movable carriage includes a double acting hydraulic shock absorber rod which engages, respectively, at its forward and rearward stroke limits, an adjustable stud in the front portion of the frame and a fine adjustment stop bar disposed at the rearward portion of the frame.  A pad of elastomer material also is used to cushion and reduce impact noise of the shock absorber.
