Abstract: A method and device for pressurizing the flow of venous blood in the portal vein to a diseased liver. The method comprises introducing arterial blood into the flow path of the venous blood in the portal vein. The device comprises an elongate chamber, the ends of which are adapted to be connected to the ends of the portal vein from which a section has been removed to provide a substitute flow path for the removed section, interiorly thereof a nozzle facing in the direction of flow and a conductor, one end of which is connected to the nozzle and the other end of which is connected to an arterial vein.

Abstract: A police stick comprising an elongate metal tube closed at its opposite ends and filled with a cellulose polystyrene and a rigid handle fixed to the tube nearer one end than the other such as to divide the stick into a short portion which, in conjunction with a handle, facilitates manipulation of the stick and a long portion at the other side by means of which the execution of the maneuver is accomplished.

Abstract: A work table for use in occupational therapy comprising a table top supported on a platform for adjustment of its working surface from a horizontal to an angular position relative to the horizontal, one or more flexible cords entrained about pulleys rotatably mounted at the far or upper edge of the table top with respect to a person using the same with one end resting on the surface of the table top and the other end hanging downwardly from the table top over the pulley, with implement holders attached to the ends resting on the table top and weights or springs attached to the overhanging portions of the cords.

Abstract: A paint stirrer paddle comprising a long, narrow, corrosion-resistant metal blade having lengthwise thereof portions displaced from the plane of the blade, said portions being concavo-convex in transverse sections, of different length and of different width, and the part of the blade containing the displaced portion of lesser width and length constituting the handle of the paddle.

Abstract: Headgear comprising a head-encircling band of extruded or molded thermoplastic having a channel formed along one edge and a transparent crescent-shaped plastic visor attached at its concave edge to the band within the channel so that said edge is concealed within the channel and said transparent visor, embodying within its diameter a pocket provided by a layer of plastic welded thereto within which is sealed a logo or emblem.

Abstract: A mixing valve comprising a rigid structure containing an interior recess and inlet and discharge ports in communication therewith, and weir plates and a slide plate confined in the recess for movement of the weir plates transversely of the recess with respect to the ports and for movement of the slide plate longitudinally of the recess with respect to the ports, said weir plates and slide plate containing openings which in predetermined positions of the plates are aligned in exact registration with the ports, and which can be moved relative to each other and to the ports to vary both the ratio of the fluids to be mixed to each other and the total flow of the fluids through the mixing valve.

Abstract: A reactor for generating combustible fuel gases comprising a chamber, an inclined grate extending from adjacent the top of the chamber to near the bottom and sloping forwardly within the chamber from the top to the bottom, said grate dividing the chamber into a primary chamber at the forward side of the grate and an antechamber at the rear side, a conveyor for delivering a solid fuel such as wood chips and other chopped-up woody material to the upper end of the grate at a rate to maintain a continuous bed of fuel from top to bottom, a blower for delivering primary air to a plenum chamber at the downwardly facing side of the grate to sustain combustion of the fuel at the lower end of the bed and to generate sufficient heat above the place of combustion to effect destructive distillation of a portion of the fuel in the bed above the place of combustion said primary air at said place of combustion converting the charcoal remaining after distillates have passed off descending from the place of distillation to CO

Abstract: A combination tension and slub catching device wherein there are relatively fixed and movable members disposed in confronting relation to each other which define a narrow yarn passage, one of which is comprised of a plurality of narrow bars disposed transversely of the path of movement of the yarn and which are individually yieldable as an enlargement passes through the yarn passage and the other which is a rigid bar disposed longitudinally of the path of movement of the yarn, and wherein there is linkage which supports the rigid bar for movement rectilinearly relative to the narrow bars to vary the width of the yarn passage and a device responsive to changes in tension in the yarn connected to the linkage for adjusting the width of the yarn passage with changes in the tension of the yarn.

Abstract: A bleacher stand of the telescoping kind, wherein a plurality of sections each including a platform and a seat are arranged to be stacked for storage in a vertical column, with the sections situated one above another and to be withdrawn from said stacked position to an extended position wherein the sections are stepped, characterized in that there are guard rails fastened to the ends of the platform portions of the sections which slope upwardly and outwardly therefrom so that when the sections are stacked the guard rails nest one within another.

Abstract: A spring assembly comprising, spaced pairs of crossing wires welded at their intersections such as to form a dimensionally stable structure wherein the pairs of crossing wires define seats for attachment thereto of the end loops of coiled springs, characterized in that at least two of the wires of the seats are spaced apart a distance less than the distance of the diameter of the end loops and contain deviations perpendicular to the plane of the structure providing longitudinal downwardly facing openings and an upwardly facing opening between the downwardly facing openings and wherein the end loops have arcuate portions which pass through the downwardly facing openings from the inner side outwardly and deviating portions which pass through the upwardly facing openings from the outer side inwardly and wherein the distance between the deviating portions and the end loops is less than the distance between the wires.

Abstract: Apparatus for removing waste, lint, dust, dirt and other accumulations of solid matter from the underside of machinery, especially textile machinery such as carding machines while the latter is in operation or not, comprising a frame designed to be installed beneath the machine on the floor on which there is reciprocally mounted a wiper arranged to travel over the floor in reciprocation so as to traverse the entire area beneath the machine, vacuum chambers at two of the opposite ends of the frame having open sides parallel to the wiper which are closed by the wiper when the latter reaches an end position and a timer operable to connect the chambers to a vacuum source as the wipers are moved to a position closing them to remove the waste swept into the chambers by the wiper.

Abstract: An adhesive tape dispenser provided with finger gripping openings for mounting the dispenser on the back of the hand so as to enable holding the dispenser on one hand while pulling the tape from the dispenser with the other hand and severing it so that the fingers of both hands can be employed to apply the severed tape.
