Abstract: An adjustable flood light enclosed in a waterproof casing is mounted for unlimited rotation between spaced support legs fixed to a base. The light source within the enclosure is carried by a support leg through which its wiring passes and it does not rotate with the enclosure. The enclosure may be clamped to one or both support legs to secure it in any desired angular adjustment.

Abstract: A partition formed of two spaced panels forming outer wall surfaces. The partitions are spaced by a paper honeycomb structure, passages in the honeycomb being substantially perpendicular to the panels. There are elongated H-shaped members fitted on each of two opposite ends of the panels, the H-bar of the members being adjacent the panel end edges. There is a partition stabilizing bar extending centrally between the panels and extending through a space between two sections of the honeycomb. The stabilizing bar is threaded at both ends and secured to and through the H-bars of the H-shaped members so as to prevent bowing or collapse of the partition in the direction of the bar.The method includes the steps of putting the partition together, particularly the steps of inserting the stabilizing bar between the honeycomb sections after they have been secured between the panels and of securing the stabilizing bar to the H-shaped members.

Abstract: The method of making lenses for the eyes from an improved modified polymerization product of methyl methacrylate. The product is in the as-cast form from which satisfactory lenses can be made, but is improved in optical clarity and wetability by heat treating and shrinking the product in a linear direction and thickening the product in another direction prior to cutting the product for making the lenses. After cooling the lens blanks are cut and the lenses are made by conventional grinding.

Abstract: Disclosed is a table-easel which supports a working surface in such a manner that it is readily movable in three directions, height, tilt, and rotation. The height adjustment is achieved by means of a pair of telescopically assembled uprights on a base and support frame which are raised and lowered by a double action turnscrew. The working surface is provided by a tabletop mounted on a cross shaft rotatably supported between the upper ends of the support frame, and tilt is achieved by rotating the cross shaft about its substantially horizontal axis. A locking structure is provided at one end of the cross shaft to lock the shaft in a particular tilt position. To permit rotation of the tabletop about a central axis normal to its surface, a pair of trunnion plates are provided. The tabletop is attached to one of the plates, and the other is attached to the cross shaft.

Abstract: A machine characterized by a horizontally oriented conveyor for transporting an open-sided wall panel, a chute having a discharge orifice at its lower end for filling the panel with pulverized cellulose fibers, and a series of roller brushes transversely related to the path of the panel for alternately packing the cellulose in the panel and sweeping excess material therefrom.

Abstract: A system and apparatus employs a photo sensor moving relatively to specially configured garment hangers to register electronically the number of garment hangers and in turn the garments suspended therefrom. The light source may be fixed at a specific location and the hangers movable with respect thereto or the light source may be movable with respect to stationary hangers.

Abstract: A prefabricated consumable assembly for forming a concrete wall structure includes a pair of spaced apart side plates interconnected on their ends by transverse tie members. A single or a pair of insulating panels is positioned within the side plates and structure is associated with each tie member which defines grooves for receiving and holding the side edges of the insulating panel or panels. The groove defining structure may be formed by a detachable clip mounted on the tie members or entirely or in part integral with the tie members. Mechanism is provided for interlocking assembled ones of the prefabricated assemblies to form a wall structure including an inside corner. The side plates may be arranged for bending to form corners.

Abstract: The device is comprised of a guide tube having an inner end cutting edge and during insertion, carries a stylet to prevent the collection of blood and skin tissue. Adjustable guard means are on the tube for predetermining and limiting the depth of entry. After the tube has been inserted to the proper depth, the stylet is removed and a hollow needle is inserted through the tube and the bone structure into the marrow cavity to obtain a marrow sample. There are means on the needle to provide for the predetermined and limited depth of entry of the needle and motor means are provided to rotate the needle to cut through the bone and enter the marrow cavity to obtain a marrow sample. In addition after the needle has been removed, the guide tube is adapted to penetrate the bone and be moved into the marrow cavity, at which time aspiration means are connected to the outer end of the tube to aspirate marrow into the aspiration means.
