Abstract: Elongated loads, such as rolls of materials, conveyor rollers or drums are movable by a five-wheel carrier apparatus comprising an elongated frame with rear wheels for carrying the load and a tow dolly which comprises a single front wheel and a pair of swivelling rear wheels which seat under the front end of the carrier frame.

Abstract: A sound reducing enclosure for a vibratory feeder includes a cylindrical base assembly which may be in one piece, or alternatively in two halves for ease of installation and maintenance of the equipment within the enclosure. The cylindrical base assembly rests upon a base plate comprising two flat half circles of 1/4 inch aluminum with the space between at right angles to the split between the cylinder halves and bounding a square hole for mounting clearance of vibratory feeder bowl equipment. A transparent generally hemispherical dome assembly of 1/4 inch plexiglass is hingedly secured to the top of the cylinder base assembly for trapping sound within the enclosure while allowing observation of the machine operations.

Abstract: A tape switch near the edge of a bed frame closes a warning signal circuit when the weight of a patient near the edge of the bed presses on an actuating switch arm that is cantilevered from the bed frame.

Abstract: Substituted quinones are catalytically hydrogenated in the presence of a mixture of (1) low unbranched alcohols and (2) hydrocarbons which are inert and fluid under the conditions of the hydrogenation reaction and which may be aromatic, aliphatic or cycloaliphatic to economically produce corresponding substituted hydroquinones of high purity and low discoloration and in high yields thereof.

Abstract: A sequence of light emitting diodes are progressively illuminated with progressively increasing instantaneous amplifier output signal amplitude with the last pair of light emitting diodes illuminated simultaneously to indicate amplifier clipping.

Abstract: A waveguide for submillimeter and infrared wavelength range electromagnetic radiation comprises a metal grating with a grating constant criterion: ##EQU1## BEING GREATER THAN (2/.lambda.).sup.2, WHERE .lambda. IS WAVELENGTH OF AN ELECTROMAGNETIC WAVE PROPAGATING FREELY IN THE SURROUNDING MEDIUM AND G.sub.X, G.sub.Y ARE GRATING CONSTANTS IN ORTHOGONAL DIRECTIONS. The constants g.sub.x, g.sub.y may be equal to each other or different.

Abstract: An electronic voting machine includes a number of terminals to facilitate accommodating virtually any ballot with nearly the minimum amount of apparatus for the particular ballot. A display lists the candidates for each office beside an identifying tag. A poll worker actuates a switch which enables the apparatus to receive vote selection indicated on a keyboard by the voter. The voter operates a switch to identify the office or issue being voted and then enters his choice on a keyboard to cause a signal representative of his selection to enter a temporary storage means and be illuminated on a display means. The voter turns a switch to the office or issue voted upon, enters a number representative of the candidate or issue decision selected and sees his vote displayed as it enters storage.

Abstract: An intense light source, preferably of high monochromaticity, having its beam modulated at a frequency corresponding to an acoustical resonant frequency of a sample chamber energizes the sample chamber along its axis. A photoelectric detector provides a signal related to this modulation for comparison with an acoustical signal provided by a microphone in the sample chamber. Means are provided for adjusting the modulation frequency so that it corresponds to the acoustical resonant frequency of the sample chamber as determined by a maximum in the amplitude of the amplified acoustical signal. An integrator may respond to the amplified acoustical signal to provide an indication of the energy absorbed by the medium in the sample chamber at the light wavelength and thereby the concentration of certain species in the sample chamber.

Abstract: Noise generation by machines having cam driven reciprocating elements is reduced in a machine wherein the cam-follower linkage comprises a double walled cam slot, a follower roller within the slot and spring means for moving the follower from the trailing wall to the leading wall of the cam slot.

Abstract: A plastic or clay drain system includes porous plastic or clay pipes at least partially covered with filter material and a dispenser of tannin for introducing tannin into the drain flow.

Abstract: A whole body imaging system rapidly forms a quality image of the bony structure, soft tissue or specific organs of a patient who has been injected with a suitable radioactive tracer chemical. A radiation detector head assembly includes a number of detector subassemblies, each having a lead collimator with tapered holes for admitting gamma radiation from a small area of the patient to a scintillation crystal that converts the gamma rays admitted by the collimator into visible or ultraviolet energy pulses. A photomultiplier converts these pulses into electrical pulses. A row of equally spaced detector subassemblies reciprocate within a nonreciprocating lead shield along the long axis of the array over a distance substantially equal to the separation between adjacent ones of the small areas.

Abstract: A stable, high field, high current conductor is produced by packing multiple, multi-layer rods of a bronze core and niobium or vanadium inner jacket and copper outer jacket into a pure copper tube or other means for forming a pure copper matrix, sealing, working the packed tube to a wire, and by diffusion, heat treating to form a type II superconducting, Beta-Wolfram structure, intermetallic compound as a layer within each of several filaments derived from the rods. The layer of Beta-Wolfram structure compound may be formed in less than 2 hours of diffusion heat treatment in a thickness of 0.5-2 microns.
