Abstract: Method of and apparatus for forming (casting) closed-ended hollow tanks of preferably circular or modified circular section and of diameter and height (length) ranging from small up to one hundred feet in diameter, a thousand feet in length and weighing one hundred million pounds, such as are suitable for under polar-ice transport and thereafter storage of petroleum, and for other uses as well. Forming and casting of such tanks is achieved preferably by slip-forming walls of concrete tanks (although conventional concrete forming and casting procedures and apparatus may also be employed), in ocean-depth water in which the tank is progressively submerged as forming and casting proceeds.

Abstract: An angle-dressing tool for dressing angular surfaces on rotating grinding wheels and the like characterized by a dovetail way member and means for setting same in a selected one of a plurality of angular positions about a horizontal axis, leadscrew and nut means operative in a hollowed-out longitudinal recess provided in the way portion of said dovetail way member, said nut being actuable linearly in opposite directions with rotation of the leadscrew, a dovetail slide member having ways complemental to the ways of the way member and being affixed to said nut for linear motion therewith and being further movable to angular positions in accordance with the angular setting of the dovetail way member, a block affixed directly to the dovetail slide member and partaking of linear and angular motion therewith, and an uprightly extending diamond-tipped shaftform member mounted in said block for movement therewith.

Abstract: A scheduling board providing for the orderly listing of jobs or operations scheduled and/or contracted to be performed and the progress thereof in relation to the time allotted to each for their completion, said board incorporating an elongate, relatively narrow-width slideway extending along one side edge thereof for the reception of a plurality of discrete "day-date" tabs arranged in column formation therein, and further incorporating a wider channel disposed to the side of said slideway adapted to be filled with a multiplicity of transversely extending semi-rigid strips inscribed on their face with job or operation data, the vertical height of each of said strips being a known fraction of the vertical height of the day-date tabs, said column of day-date tabs being slidable upwardly in response to upward push force applied to the lowermost or lower tabs upon each uppermost tab having been removed from the slideway, and said topmost strip(s) being manually liftable from said channel by bowing force applied f

Abstract: A parenteral fluid administration set comprising a plastic bag adapted to be supplied with a predetermined quantity of the parenteral fluid, said bag being foldable over on itself about a transverse fold-over line, a floating siphon enclosed within the plastic bag adapted to follow the level of the parenteral fluid supplied thereto, said floating siphon being adapted to be forced relatively downwardly to substantially its lowermost position in the plastic bag responsive to folding over of the upper portion of said bag on its lower end portion about said fold-over line, thereby immersing the float of the floating siphon in fluid contained in its lower end, as effects conditioning of the floating siphon for operation, the outlet leg of the siphon terminating in a fluid outlet end, said floating siphon being rendered operative to dispense fluid from the plastic bag through said siphon outlet end upon the plastic bag being unfolded and suspended from its upper end.

Abstract: The combination of a grooveless cylindrical shaft-form member and an open-ended friction-grip ring of the external form and of the general type disclosed in Heimann U.S. Pat. No. 2,574,034, dated Nov. 16, 1951, but which rather than being designed to grip the shaft surface on which it is assembled all around its arcuate inner edge, as per said Heimann patent, is instead provided with illustratively three inner-edge planar prongs whose inner ends or tips lie on a circle which is concentric with the circle of the outer-edge circle of the ring body and which is eccentric by a predetermined amount to the inner edge of said ring body, such eccentricity being in the direction of the ring ends. One said prong extends inwardly from the middle section of the ring body having maximum section height and two of said prongs extends inwardly from end sections of the ring body having minimum section height.
