Abstract: LANTHANUM-GADOLINIUM PHOSPHATE X-RAY PHOSPHORS     ABSTRACT OF THE DISCLOSURE   X-ray phosphor compositions of the formula:             La1-XGdxPO4 wherein x is from about 0.01 to about 0.5, when incorporated into conventional x-ray intensifying screen, improve the resolution, of the image in the resulting film. The lanthanum gadolinium phosphate under x-ray excitation has a line emission with a peak at about 312 nanometers. A solid state process wherein the respective rare earth oxides and ammonium orthophosphate are first heated together under controlled temperature conditions and then reheated with a suitable alkali metal phosphate flux', followed by a nitric acid treatment, enables the production of materials having particle sizes suitable for x-ray screens . Use of the lanthanum-gadolinium phosphate in screens in conjunction with conventional base films effectively eliminates distortion resulting from cross-over.

Abstract: PROTECTIVE CASE FOR ELECTRICAL INSTRUMENTS             ON CIRCUIT BOARDS                  ABSTRACT OF THE DISCLOUSURE A protective case for an electrical instrument on a circuit board, arranged to mount the instrument upon a panel in an opening provided therein.  The case is character-ized by a housing having an end opening for introduction of the circuit board therein and a snap-in mounting structure for automatically and securely mounting a circuit board with in the housing.  The mounting structure includes means forming a ledge, provided for example by four corner platforms molded into the housing, for supporting one side of the circuit board.  Two pairs of opposed resilient fingers, pref-erably molded integrally with the walls of the housing, extend with an inward cant along the path of the circuit board from opposite interior sides of the housing to be flexed outwardly by the edges of the circuit board as it is introduced into the housing.  The resilient fingers terminate in front faces, preferably formed with beveled stepped surfaces, which are spaced from the ledges to allow the resilient fingers to flex inwardly to fit their front faces against the opposite side  of the circuit board when it is positioned with its one side in contact with the ledge.  The circuit board thus becomes securely mounted in the housing automatically upon its introduction therein, without resort to separate fasten-ing means or tools.  The case further has a back wall aper-tured to receive connector pins on the circuit board, a front cover, and resilient catches extending outwardly from other side walls of the housing for attachment of the housing to an instrument panel.

Abstract: ABSTRACT OF THE DISCLOSURE Photographic apparatus for use with film units of the self-developing type.  The apparatus includes a coil of opaque sheet material mounted adjacent an exit slot of the apparatus in position to be engaged by a leading edge of an exposed film unit as it is being advanced to the exterior of the apparatus by a pair of pressure-applying members.  The sheet material is uncoiled by the advancing film unit so as to progressively cover, in lighttight relation, por-tions of the film unit which have been treated with a processing composition so as to prevent further exposure of untreated portions of the film unit by ambient light being transmitted lengthwise along the film unit.  After the sheet material has been completely uncoiled, it is adapted to return towards its coiled configuration where it cooperates with other structure for releas-ably retaining the film unit in engagement with the apparatus after the latter has moved out of engagement with the pressure-applying members.

Abstract: TITLE: REAMER          ABSTRACT OF DISCLOSURE:     A roller reamer for boring holes in the earth is useful for both well drilling and in mining.  The reamer rollers are replaceably mounted on the reamer body in a manner that facilitates easy replacement so that the body can be reused after its initial comple-ment of rollers is worn out.  To that end, the rollers are rotatably mounted on shafts whose ends are support-ed by blocks inserted in the reamer body.  To prevent shaft rotation, one end of each shaft is welded, pinned, or otherwise nonrotatably anchored to its mounting block.          Each block makes an interference fit with the body socket in which it is disposed.  The blocks are stepped for quick release.  Access openings to the backs of the blocks facilitates knockout.  Knockout of the stepped blocks is achieved by wedge means.   Drilling mud may have access to contacting surfaces of rollers and shafts to lubricate same.          Protective seal means may be provided between each roller and shaft at the upper ends thereof so that the mud must flow upwardly to reach the space between shaft and roller and dense solids will be excluded by gravity.          Grease lubrication may be provided, the rollers being sealed to the shafts at both ends.         With mud lubrication, axial loads on the rollers may be taken by the ends of the rollers bearing on the blocks.  With protected mud lubricaticn and grease lubrication, thrust may be taken by thrust bearins surfaces provided within the protected or sealed zone, e.g. by a flange on each shaft engaging an internal groove formed by a two piece roller, or a ball lock between opposed annular grooves in shaft and roller.

Abstract: ABSTRACT OF THE DISCLOSURE         A compressor-expander having a vaned rotor in which the vanes rotate about an axis which is canted with respect to the rotor axis.  The housing of the device has a disc-shaped main cavity having adjacent hub recesses which are concentrically spherical.  The cavity is in the form of a doubly truncated sphere canted with respect to the shaft axis.  The rotor has a central spherical portion for mating with the recesses and includes an integral Saturn-like ring extending to the outer wall of the cavity to divide the cavity into compressor and expander sides of complimentary circular wedge shape.  The vanes occupy radially extending slots in the rotor and serve to separate each side into successive chambers which vary cyclically in volume as the shaft rotates without requiring the vanes to bodily reciprocate either radially or axially.  The cavity is provided with compressor and expander inlet and outlet ports, a primary heat exchanger being connected between the compressor outlet port and the expander inlet port, so that air entering the compressor inlet is compressed and heated, the heat of compression being removed in the heat exchanger, following which the air is expanded and cooled for discharge in the cooled state.  Preferably a secondary heat exchanger is connected between the expander outlet and the compressor inlet to form a closed system operated at a pressure above atmospheric.  By appropriate location and connection of the ports, the device may be utilized as a two-stage compressor or expander.
