Abstract: A reflector which particularly reflects light at a selected peak wavelength in the vacuum ultraviolet (VUV) region and which absorbs light outside the VUV, particularly in the visible light region consists of a reflective surfaced substrate such as polished aluminum, a dielectric layer over the reflective surface, and a thin film of one or more of the six, non-radioactive metals tungsten, rhenium, osmium, iridium, platinum and gold. The thickness of the dielectric spacer layer is approximately one fifth that of the selected peak wavelength, and a second dielectric layer of the same thickness may be applied over the metallic thin film.

Abstract: An X-ray tube including a chamber enclosing an anode disc rotatable about an axis, and movable transversely with respect to that axis, the tube also enclosing an electron beam source for projecting electrons along a beam directed towards a planar surface of the anode disc. The beam source is disposed so as to direct its beam at an acute angle of incidence to the planar surface of the anode disc and produce X-rays which are thereupon reflected from the anode disc through a window in the chamber.

Abstract: An artificial decorative rock of foamed synthetic plastic having a body with an outer surface resembling the concavities and convexities of a natural rock has its outer surface coated with a strengthening layer of epoxy resin filled with hard sand-like particles which give the outer surface a rock simulating, grained texture. By forming a hollow within the surface of one body to complimentarily accommodate the outer surface of another body, one or more artificial decorative rocks can be nested, one within the other. By further shaping the uppermost outer surface of such hollow body to provide a stable support base, the body with the hollow extending upwardly can serve as a container.

Abstract: X-ray apparatus comprises a U-shaped support having two hollow, horizontal arms. On the end of one arm is mounted an X-ray tube and on the other an X-radiation receptor both guided for movement on a radiation axis.A counterweight within one hollow, horizontal arm is guided for movement parallel to the X-ray tube, transversely of the arm. To counterbalance the X-ray tube a lever attached to the tube has sliding pivots at a fulcrum and the counterweight allowing the lever arm to change its length without changing the leverage ratio.

Abstract: An X-ray apparatus has a moveable support on which are slidingly mounted an X-ray tube, an image intensifier and a film holder, these radiation components defining a common radiation axis. By including a reversible motor connected to a system of clutch operated drive linkages the X-ray tube and receptors can be selectively and reciprocally moved along the radiation axis in either an independent or interdependent manner so as to preserve a radiologically desirable Source to Image Distance (SID) while simultaneously accommodating other X-ray examination requirements such as patient comfort, safety, and desired examining position. The X-ray tube is attached to a lever arm and the image intensifier and film holder are each moved by respective cables travelling around respective drive pulleys and idler pulleys. Both the X-ray tube and receptors are closely counterbalanced by counterweights respectively moved by the cables.

Abstract: An energy conserving circuit for controlling supply of electrical power to various loads such as a street lamp or a hot water heater comprises a photoelectric device for starting a timer when a change from daylight to dark is sensed at sundown, and a load power control responsive to the timer to switch between power-off and power-on states. With a street lamp the timer and power control means are connected to switch the power control means to power-on state at the beginning of the delay period at sundown and later, well before sunrise, to switch to power-off state. In the case of a household hot water heater the switching of the power control to power-on state is delayed until the peak demand hours have ended after sundown. The photoelectric device will normally cause the power control to switch to power-off state at sunrise.

Abstract: A jig with multiple units each for assembling and slicing two sandwiches at a time has a base with four upstanding walls for each unit surrounding a generally rectangular volume shaped to receive two pairs of bread slices and a filling between each pair. At two diagonal corners of the walls there are narrow, aligned slits receiving and guiding a knife for slicing the two sandwiches into two symmetrical pairs of stacked halves. The other diagonal corners are relatively widely spaced to form finger accesses for gripping the sliced sandwiches. A hollow in the base at these other corners further facilitates finger access. A removable cutting slab lying between the walls permits lifting both sandwiches at once.

Abstract: Encapsulation of electrical circuitry by high pressure injection molding of an insulative thermoplastic material about electrical components supported in a pre-formed carrier which is itself supported in an outer mold. The carrier has an internal configuration of lands and grooves which facilitates circuit insertion, the walls of which carrier are yieldable to flex inwardly to permit registration of the carrier walls with the outer mold and to securely hold the circuit during the injection process during which both the mold and the carrier are filled. The carrier is vented to insure complete encapsulation throughout the circuitry therein.

Abstract: Apparatus for making the finishing cut on the internal outline of a rough cut female die has two carriages one sliding in one direction upon the other, and the other carriage sliding upon a base at right angles to the first. A male punch comprising a template of the outline to which the die is to be finish cut is mounted on one carriage and the die or workpiece is mounted in an indexing work holder on the other carriage. The template engages a tracer finger fixed relative to the base and to a hacksaw blade which finish cuts the die or workpiece by strokes with the plane of the blade perpendicular to the die surface being cut. The tracer and blade are in common planes to which one carriage moves perpendicularly and the other parallel. The cutter blade and tracer respectively engage the die or workpiece and punch or template in the same direction so that cutting action urges the template and tracer into engagement.

Abstract: A X-ray tube is mounted on the same mobile base as its power supply which includes a pair of motor driven flywheels. The motors can be run from 120 volt outlets to bring the flywheels to a predetermined speed. The motors are then shut off and the flywheels drive electric generators. A motor controlled variac maintains the power output of the generators constant as energy is drawn from the flywheels and they slow down. The power output is switched through a step-up transformer and a rectifier to the load of the X-ray tube. The two flywheels are equal and opposite in angular momentum by counterrotation and therefore cancel the effect precessional or other movement to the mobile base when energy is drawn from them.

Abstract: Facsimile apparatus for line by line recording of different kinds of weather map, satellite and other graphic data distinguishes the different characteristics of the transmitted electrical data signals and records them in suitable aspect ratio, despite the fact that the various signals are transmitted at different line rates and are intended for recording at different line densities. The apparatus also enhances the contrast of the recording and can enlarge the original graphic information.

Abstract: A camera for taking a plurality of photographic images utilizing a single focal plane, usually a plate or a sheet of film, which is fixedly disposed with relation to the lens. The camera is divided into a plurality of focal locations arranged about a rotatable mirror associated with the lens and one or more additional mirrors which reflect an image from the rotatable mirror to a portion of the plane. The camera is capable of taking a succession of pictures and displaying them in a tightly packed, rectangular and non-overlapping array around the perimeter of the focal plane. The image beam from the lens is directed at each successive focal location by the rotatable mirror and the additional mirror which reflect the beam to image at the focal plane. To obtain the desired arrangements of the plurality of images on the fixedly disposed focal plane, the image centers are disposed at different length radii from the lens and rotating mirror axis.

Abstract: A clip for engaging through an aperture in an ID card is molded of one unitary body of plastic comprises two elongate stiff parallel members joined at their middle by a flexible web forming a hinge. On one side of the hinge the members form opposed jaws and at the other side of the hinge one member forms a spring biased toward the other member to urge the jaws closed. The spring forms a loop capable of engaging through an aperture in an ID card. The loop is offset from the hinged members to allow the card to hang parallel alongside the hinged members.

Abstract: A waste gas recovery system employs a compressor which takes in raw waste gas from an inlet knock-out drum and passes compressed gas through a heat exchanger to an outlet knock-out drum. The temperature at the outlet of the compressor is sensed by a device which operates valves to inject liquid coolant into the compressor inlet and to re-circulate gas back from the outlet of the outlet knock-out drum to inhibit an excessive temperature rise. A pressure-sensing device senses the pressure of the gas passing into the compressor and controls both the speed of the compressor and an adjustable throttle valve to regulate the gas flow. The throttle valve is closed automatically should there be a fall in the pressure of the gas at the inlet below a safe level. In this event, further pressure-sensing devices act additionally to close the recirculating gas valve and a further valve in the main inlet flow path to reliably isolate the compressor.

Abstract: A monochromator has three ports or slits including two entrance slits and an exit slit. A single mirror and a diffraction grating define a first, folded path between an entrance slit on one side of the housing and an exit slit on the opposite side of the housing. The mirror is movable in and out of a second path between the second entrance slit and the grating so that a second path may be completed from the second entrance slit to the grating and thence to the exit slit. Alternatively two of the ports may be used as exit slits and one as an entrance slit.

Abstract: A facsimile recorder has a motor driving a scanning element and also generating recorder pulses occurring proportionally to the recorder scanning speed. A circuit for synchronizing the scanning motor with incoming framing pulses of a facsimile signal comprises a first dual data type flip flop with a first output, a first input receiving the framing pulses and a second input receiving the recorder pulses. The flip flop produces a gating pulse of duration corresponding to the interval between asynchronous occurrence of framing and recorder pulses which causes transmission of power to the recorder motor during the asynchronous interval. Consequently the motor speed and hence the period of the recorder pulses are varied in proportion to asynchronism until the framing and recorder pulses are coincident when the motor is synchronous with the framing pulses.Power is transmitted to the recorder motor at a particular frequency derived from a frequency standard.
