An elongated handle is provided including an endwise outwardly projecting elongated permanent magnet embedded in and projecting lengthwise outwardly from one end of the handle. A hollow cap is provided and is removably telescopingly engageable over the end of the handle from which the permanent magnet projects and the cap loosely encloses the outwardly projecting end of the magnet. The cap is removable from the end of the handle from which the magnet projects and is, alternately, removably teles...

An apparatus for analyzing certain properties of an object with a beam of radiation capable of emitting fluorescent x-rays by (1) aligning a pivotally mounted radiation-emitting generator with a pivotally mounted radiation detector relative to a specific point on the object by providing for a beam of visible light to be separately directed from the generator and detector, (2) generating and projecting a beam of radiation against a selected portion of the object, which includes the points to be a...

A method and an apparatus are provided for ultrasonically inspecting a cylindrical object. The object is placed between the poles of a magnet to create a circumferential magnetic field in the object. A group of electromagnetic transducers (EMAT's) are placed adjacent the material so that the transducers scan the entire object when it is rotated. When an RF signal is applied to the transducers, elastic waves are generated in the material. These elastic waves reflect from defects in the material a...

Pellicles of para-xylylene polymers are used as the sole support media for masses of objects supported thereon. The supported objects can be combined with the pellicle either during the formation of the pellicle or after the pellicle has been manufactured. The composite article is used wherever it is desirable to provide a support media which has as little detrimental influence as possible on the intended function of the supported object.

A method for packaging an object, in particular a root ball of a tree, shrub or plant. The object to be packaged is placed in a socket which is surrounded by an elastic reticulate hose, whereupon the object is removed from the socket, during which operation the hose is carried along, this hose subsequently being severed beyond the object. An apparatus used for packaging an object, in particular a root ball of a tree, shrub or plant. This apparatus comprises a socket into which the object to be p...

An arrangement using C-shaped track having inwardly directed flanges and mounted upon a rotatable base is provided such that objects conveyed in the track can be separated, fixed in position, rotated or indexed, and recombined in the track.

A method of and an apparatus for the cooling of an object, such as a superconductive magnet, superconductive cable system or the like, wherein the liquid cryogen (e.g. a liquified gas such as helium) is passed continuously through or in heat-exchanging relationship with the object from a supply reservoir. After traversing the object or a cryostat therefor, the liquid cryogen is partially expanded to form a gas/liquid phase mixture which is passed in heat-exchanging relationship with previously w...

The profile of a surface of an object is determined by scanning the line of intersection of this surface and a given plane transverse to the object. A radiation transmitter provides a transmitting beam, and a radiation receiver provides a receiving beam. Deflection means causes scanning movement of one or both of the beams so that a zone of intersection of the beams scans along a predetermined line and a detector in the receiver receives radiation transmitted from a source in the transmitter and...

This invention relates to a detection system for detecting presence of moving objects such as vehicles, etc. through utilization of ultrasonic energy which includes a predetermined location provided in memory unit and having stored therein time from transmission of ultrasonic energy till reception of reflected energy corresponding thereto from a road surface, circuitry for computing difference a between immediately preceding time from transmission of ultrasonic energy till reception of reflected...

An object, such as a superconductive magnet or a super-conductor cable in a housing or cryostat, is cooled with a cryogenic fluid passed continuously from one vessel into the housing or cryostat and then conducted after expansion into a second vessel where part of the cryogenic liquid is converted to vapor by expansion. A vapor/liquid separation is carried out in the second vessel and the liquid phase is delivered to a third vessel serving as a storage reservoir and intermittently connected to t...
