Abstract: An electronic circuit for energizing an electric lamp associated with an alarm clock. Alarm circuitry within the clock energizes an electronic flasher that delivers a control signal to a bidirectional switch means in an A.C. circuit containing the lamp. The switch means triggers a two direction silicon controlled switch means in the lamp circuit. The lamp provides an optical alarm that can be used as a wake-up signal by persons who are deaf but who can see.

Abstract: A removable, reuseable holding jig for a locking plate associated with the end cap of a railroad truck bearing in which the locking plate provides a plurality of cap screw head apertures through which the end cap holding screws project when threaded into the axle end cap of the railroad bearing. The holding jig is of the same configuration of such locking plate but of a larger size so as to overlap the edges of such plate and to be confined in the well provided by the axle roller bearings. The holding jig will position, and by a series of lugs engage the sides of the locking plate so as to prevent rotational movement thereof resulting from the rotational torque of the cap screws as they are threaded into the axle bearing.

Abstract: An apparatus for the deep heating of cancers employing two single turn coaxial coils of varying diameter ranging from 2 inches to 6 inches which rotate synchronously in planes which are parallel to each other with the central axis of each coil lying in exactly the same line which is perpendicular to the plane of the coil. When the two coils are at 180.degree. from each other a line drawn through the central axes of both coils traverses the center of a tumor in the body which is to be heated and is not perpendicular to the two planes of rotation. The coils are placed so that the inner curvature of the rotating coil is tangential to the center of the tumor mass with the summated magnetic field of the rotating coils continuously heating the tumor with the maximum number of lines of magnetic force.

Abstract: An end plug for a semiconductor device shipping rail has a unitary tolerance compensating portion. The tolerance compensating portion is preferably an end of the end plug which comes in contact with semiconductor devices located within a shipping rail or carrier. The end plug is dimensioned in a manner to provide a friction fit within the shipping rail, and in a preferred embodiment the tolerance compensating end has a hollow portion so that the end of the end plug that contacts the semiconductor devices can easily flex to compensate for stacking tolerance buildup and to act as a shock absorber.

Abstract: The Raman scattering detector of this invention includes a source of collimated monochromatic illumination, a cube formed of two right angle prisms, a holographic optical element disposed between the prisms, a concentrating lens, a focusing lens and one or more photo detectors. The illuminating beam passes through the cube and is concentrated by the concentrating leans to a sample. Scattered light returned to the concentrating lens is substantially collimated upon return to the cube. The holographic optical element diffracts light at desired Raman wavelengths approximately 90 degrees without substantially affecting the original wavelength. The holographic optical element further disperses light at desired Raman wavelengths permitting them to be separated. The diffracted and dispersed wavelengths are focused on one or more detectors by the focusing lens.

Abstract: An equilibrium growth dispersion for use in liquid epitaxial growth at a predetermined growth temperature of a compound including at least two constituents. Predetermined quantities each of the constituents are placed in a container, the predetermined quantities being such that the total relative proportions of constituents will provide a saturated solution of one of the constituents in another of the constituents at the growth temperature, and the container with the predetermined quantities therein is heated to a temperature not less than the growth temperature to dissolve the constituents and is maintained at such a temperature for a period of time sufficient to produce a solution of one of the constituents in the other. The solution is then rapidly solidified, typically by quenching, to form the equilibrium growth dispersion which comprises an essentially homogeneous dispersion of particles of the one constituent (the solute) in the other (the solvent).

Abstract: A trocar sleeve characterized by an annular flange adjacent a proximal end, a disc-shaped annular stop spaced from the annular flange in a distal direction and helically extending thread extending from said annular disc-shaped stop toward the distal end to prevent the removal of the sleeve from a puncture. The sleeve is used in conjunction with the trocar, which is provided with a disc-shaped annular stop between its ends, which engages the proximal end of the sleeve as the trocar is inserted therethrough and with cutting edges of the trocar being exposed to the distal end of the sleeve. The sleeve and trocar form a device which is used to form a puncture in the wall of a patient and then, after the distal end of the sleeve has been inserted in the puncture, the sleeve is rotated to thread the sleeve into the puncture to a position to prevent its removal.

Abstract: A power transmission has a housing comprised of an end support, a casing, an end cover, a converter housing, an input shaft, an output shaft and a pair of identically dimensional countershafts. A bushing and oil feed sleeve are positioned on each end of each countershaft for cooperating with the end support connecting the housing for alignment therebetween and with the casing for alignment therebetween. Each countershaft has a pair of ratio gears rotatably disposed thereon and meshing with respective output gears rotatable with the output shaft and a friction clutch is provided for each ratio gear. Four of the friction clutches which are disposed on the countershafts are identical in construction. A fifth clutch assembly, in line with the input shaft, can be shortened, if desired, by the elimination of one friction plate and one reaction plate.
