A thermoluminescence dosimeter is integrated with a dosimeter-holding member to simplify and assure its handling as well as to prevent the generation of miscellaneous luminescences, for example, a luminescence due to the heat of friction. The reliability of the thermoluminescence dosimeter is thereby greatly improved in measuring dose.

A tray is provided having a peripheral frame of extruded plastic material. The frame includes an upwardly and outwardly inclined wall provided with a vertical wall near its lower extremity spaced upper and lower flanges define an inwardly opening channel which engages the marginal edges of a bottom panel. The extrusions forming the side and end walls are secured together at the corners.

In microscopes having a photometer device disposed at or in an intermediate tube, wherein the tube is provided on one of its ends, or in the proximity thereof, at the underside with a coupling device for attachment to the stand and, on the opposite side, with a coupling device for the attachment of an ocular, the improvement comprising inserting the photometer, via a beam splitter, a tripple mirror connected thereafter, as well as an ocular, into the light flux of the intermediate tube. Other im...

An improved fishing sinker having an elongated cylindrical-shaped body of hollow construction is closed-off at its ends to define an air space therein, and carries weight or ballast means at its lower end. A ringlike connector is mounted on the body for up and down movement therealong, and latching finger means is provided for retaining the ring in one of a selected group of positions to provide different points of connection of a fishing line thereto. Ballast means of different characteristics ...

A plurality of spherical supports are held in place on a vehicle frame by a pair of lower rollers which engage opposite sides of each spherical support below the center thereof and a pair of upper spaced apart rollers which engage each spherical support above the center thereof. The upper and lower rollers are carried by the vehicle frame and are adapted for rotation about horizontal axis parallel to each other. Lateral movement of each spherical support is limited by laterally disposed rollers ...

Pipe having coupling elements enable lengths of the pipe to be joined end-to-end without the use of additional components. The pipe design uses a tubular body which may be extruded from clay or the like, to which mating coupling elements are affixed.

The present invention provides a member having a cutting edge with a boron-containing coating thereon, the coating being up to 600 Angstroms thick. The member may be a razor blade. The invention also provides a method of manufacturing a member having a cutting edge which includes the step of coating the cutting edge with boron to a thickness up to 600 Angstroms.

A flexible bearing is constructed of layers of elastomer and rigid shims, alternately stacked and bonded together. At least some of the rigid shims are replaced with flexible reinforcements of refractory cloth or wire screen. The reinforcing material minimizes the number of rigid shims required. In some applications, the rigid shims may be completely eliminated.

A technique for adapting an existing connector of the type having conductive pins or sockets therein to accommodate sleeve form electrical filters. A conducting shell within which filters and pins or sockets are secured is adapted for mounting to an existing connector. Any combination of one circuit to a full compliment of circuits within the connector configuration can be filtered. Those circuits not filtered will have pins or sockets which are conductive. The filtered pins or sockets are secur...

A seat assembly has a seat frame tiltably supporting a back frame for movement about an axis parallel to the intersection of planes parallel to the seat and back frames, and has an adjusting mechanism for controlling the degree of tilt from a position to the side of and exterior to the seat frame. The adjusting mechanism includes a tilt adjustment slide movable in a channel provided in the side of the seat frame and having a groove therein oblique to the direction of movement of the slide. The s...
