Abstract: Use of labeled monoclonal antibody 50 H.19 to detect the location and concentration of blood platelets in a host is disclosed. MAb 50 H.19 labeled with a label which can be detected from without the host (e.g. a radiolabel or NMR-label) is intravenously injected to immunoreact with platelets in vivo or is first immunoreacted in vitro with platelets, which are then intravenously injected into the host. By means of the labeled MAb 50 H.19 bound platelets it is possible to detect and locate thrombi, emboli, atherosclerotic obstructions, bacterial endocarditis and to do spleen imaging. In another embodiment of the invention, the MAb 50 H.19 is bound to an enzymatic thrombolytic agent and injected intravenously to permit the therapeutic application of the agent directly to thrombi.

Abstract: A knife having a foldable blade includes a locking bar which holds the blade in an open position. A release lever is provided on the side of the handle for releasing the locking bar and allowing the blade to be moved to a closed position.

Abstract: In a hot-melt adhesive system, a glue stick is provided with a transverse cross section which is acircular. A glue gun is provided with an acircular opening in the gripper housing and an acircular opening in the heating element to accommodate a glue stick. In a preferred embodiment, the major dimension of the glue stick is approximately one-half inch while the smaller dimension is slightly more than one-quarter inch. The acircular glue stick provides excellent heat transfer in the heating chamber and permits a simpler manufacturing process. The gripper housing includes a gripper element which engages a major part of the width of the glue stick and can transmit a large advancing force without becoming embedded in the stick.

Abstract: A power driven nut harvester of the invention is a self-propelled device for sweeping nuts from the ground into a housing by means of a power driven rotary drum equipped with flexible tines or with flexible rubber strip material. The power unit also propels the harvester at a substantially constant speed. The nuts are separated from debris by passing them at high velocity through a stiff bristle brush which repels the debris and directs the nuts for collection into a receiving bin. A spring loaded deflector plate adjacent the sweeper drum is kept in proper alignment by a fifth wheel maintained in constant contact with the ground.

Two track guides parallel to each other are built into or on and encircles the main frame in the lengthwise dimension adjacent to the outer edges. A continuous rubber belt which has a generally flat inner surface and in which a series of belt carriers are fixed. The carriers have bearings adapted to travel in the two track guides, such that the belt can run in guided fashion around the main frame in the lengthwise direction.

Abstract: As for high strength stainless steels and method for manufacturing the high strength stainless steels, the strength of the stainless steels are enhanced by adding an appropriate amount of both nitrogen and niobium to austenitic stainless steels, inhibiting boron, an impure element, and decreasing the carbon content. The strength of the stainless steels are further enhanced by such heat treatment as control rolling and low temperature solution heat treatment applied to the stainless steels after the control rolling.

Abstract: The present invention relates to a process for producing fiber aggregate which comprises a dispersion step of dispersing fibers in the form of short fiber, whisker, or a mixture thereof into a dielectric fluid; an orientation step of placing the dielectric fluid containing said fibers dispersed therein in a space between a positive electrode and a negative electrode across which a high voltage is applied, whereby causing individual fibers in the dielectric fluid to electrostatically orient, with one end pointing to the positive electrode and the other end pointing to the negative electrode; and an aggregating step of aggregating the statically oriented fibers while keeping the oriented step, whereby producing fiber aggregate in which said fibers are mostly one-dimensionally oriented. Small amounts of surface active agent in the dielectric liquid promote fiber orientation in addition to dispersing the fibers.
