Abstract: A method of making three-dimensional simulated stained glass objects from resins. A sheet of resin having the ornamental pattern of the object printed on it is preformed substantially to the shape of the object. The preform is inserted in an injection mold for being reinforced on one side or another with a thicker resin layer. Mounting flanges, bosses, ribs, interlocking joints and other mating configurations are formed with the reinforcing layer to enable combining a molded three-dimensional section with other three-dimensional sections to form more complex objects. The printing on the flat resin sheet is pre-distorted, as required, so that when it is formed to the contours of the object the printing will assume a proper undistorted form.

Abstract: In dental x-ray apparatus a control is provided for driving the high voltage transformer in the tube head at a frequency far above power line frequency. The transformer is driven with an inverter. A precision d-c voltage regulator that operates in an "add-on" mode and thus only handles a portion of the output current controls the voltage supplied to the inverter. The d-c voltage regulator is supplied a voltage by a transformerless a-c/d-c converter whose output is proportional to the 60 Hz power line voltage that supplies it. The x-ray tube filament transformer is also driven at a frequency above power line frequency. Means are provided to cut off power to the x-ray tube if its current does not reach a certain value within a short time after an exposure is initiated. Means are provided for isolating high voltage power circuits from low voltage control circuits.

Abstract: A low thermally conductive columbium metal stem has a heavy refractory metal x-ray target disk fastened to one end. A high thermal conductivity rotor hub comprising a cup-shaped element is fastened to the other end of the stem and the rotor hub is fastened to the end of an induction motor cylinder or liner which is coated to enhance heat emission and is induced to rotate by being coupled to a rotating magnetic field. A low thermally conductive bearing hub is fastened to the inside of the rotor hub and to a shaft which is journaled for rotation in bearings. The bearing hub enhances thermal isolation of the bearings from the hot rotor hub and hot target.

Abstract: Article orientation determining apparatus is exemplified in apparatus for determining if the tip ends of corn cobs are leading or trailing as they advance toward a kernel cutter head. The cobs pass between a column of sequentially pulsed radiation emitters and corresponding detectors which scan successive slices of the article and develop binary data indicative of the number of emitters that are unblocked during each scan. A computer uses the data to determine orientation and provides signals for controlling devices that act on misoriented articles. Means are provided for reversing the machine to clear a jam condition, for setting the number of reversals, for setting minimum acceptable cob length, for testing operation and for performing other functions. The scanner head is constructed to resist hostile environmental conditions.

Abstract: An anode assembly for a stationary anode x-ray tube wherein a tungsten target insert and an anode supporting metal sleeve are brazed simultaneously to the anode body. An axially tapered metal ferrule having a larger diameter than the sleeve is sealed into the end of a cylindrical glass envelope and the sleeve is inserted concentrically into the smaller end of the ferrule. The joint at the coterminous outside ends of the sleeve and ferrule is welded so as to seal and support the anode assembly in the tube envelope.

Abstract: In a gamma camera system, means are provided for correcting nonuniformity or lack of correspondence between the positions of scintillations and their calculated and displayed x-y coordinates. In an accumulation mode, pulse counts corresponding with scintillations in various areas of the radiation field are stored in memory locations corresponding with their locations in the radiation field. A uniform radiation source is presented to the detectors during the accumulation mode. When a predetermined maximum number of counts is reached in several memory locations, accumulation is interrupted at which time other locations have fewer counts in them. In the run mode, counts are stored in corresponding locations of a memory and these counts are compared continuously with those stored in the accumulation mode.

Abstract: An array of electrode plates are arranged in parallel and spaced apart relationship to define ionization cells in a channel within a housing that is occupied by high pressured gas. A broad beam of x-ray photons penetrates a window in the housing and produces ionization events that result in analog signals corresponding with photon energies and intensities. Conduction of the signals from the interior to the exterior of the detector housing is accomplished with a printed circuit board assembly that is sealed between the housing and its cover.

Abstract: A control console has a small and compact array of twenty-seven illuminable push buttons arranged in three continuous groups of nine each. The buttons in the upper group relate to anatomical areas in upper parts of the body, and the buttons in the lower group relate to areas in the lower parts of the body and the extremities. The middle group are control and x-ray technic variation buttons. Different anatomical regions are indicated by pictographs on the push buttons in an organized array in the upper and lower groups. Pressing at least one push button in the middle group and one in the other groups sets up and displays the x-ray exposure parameters corresponding with the equivalent of the user's priority technic, including safe patient exposure and safe x-ray tube operating time, which has been stored in a memory, for the particular anatomical region. The programmed values for tube kV, mA, mAs and time are displayed.

The shield casing and liner are comprised of resin which is impregnated with barium sulphate.

Abstract: An x-ray source, whose output is collimated into a thin fan-shaped beam, and detector means spaced from the source are mounted for scanning and orbiting jointly about a body in a partial or complete revolution to provide x-ray intensity data for reconstructing an image. The detector and source combination and the body are moved relative to each other in an axial direction for scanning the body layers in sequence. In one embodiment the x-ray source is pulsed as it scans and in another the fan-shaped beam is on continuously and readout is done sequentially so in either case a large number of intensities for each layer are obtained. A high precision encoder system is used to synchronize x-ray pulses and readouts spatially and with line frequency. Means are provided for storing the cables which lead to the rotatable source, and the detectors and other moveable components. An embodiment for scanning a body part such as a breast has means for conditioning and controlling water in which the part is immersed.

Abstract: A weather seal for the bottom edge of a swinging door comprises a roller covered with a compressible material such as carpeting. The roller is supported for rotation on spring biased arms that are attached to the door. The arms press the roller into sealing relationship with the door and doorsill when the door is closed and permit the roller to rise and fall as required to clear obstructions or irregularities in the surface over which the door swings as it is being opened. At least one end of the roller which is at the hinge edge of the door is made as a flexible tube so it will bend if it is obstructed by a wall as the door is swung open.
