  • Patent number: 4744017
    Abstract: A high tension power supply for use in an x-ray tube drive circuit which uses a step-up transformer to raise an input line signal to the desired voltage level. A partially open bridge or other suitable means permits only half cycles, for example positive half cycles, of the transformer output to be applied to fire the x-ray tube. Saturation of the transformer core during unused half cycles, for example negative half cycles, is prevented by adding a compensating impedance in series with the circuit passing the unused half cycle to the transformer primary, the increased voltage drop across this impedance as current increases in response to the transformer approaching saturation reducing the voltage across the transformer so as to maintain the average voltage across the windings during both half cycles substantially equal. This achieves "constant phase" exposures without transformer saturation.

  • Patent number: 4729238
    Abstract: A device for measuring the volume of a gas comprises a cylinder and a piston movably mounted in the cylinder. A first membrane sealingly connects the piston with the inner wall of the cylinder. The cylinder, the piston and the first membrane determine a measuring space in which a measuring conduit for the gas to be measured debouches. A second membrane also sealingly connects the piston with the cylinder inner wall. The first and second membranes determine an intermediate space in which an underpressure is generated during operation.

  • Patent number: 4655393
    Abstract: An ultrasonic liquid atomizer particularly for high volume flow rates is disclosed. An enlarged tip with a plurality of orifices is provided to increase the flow rate. A gradual transition to the enlarged atomizer tip is provided to enhance performance. The atomizer provides a substantially cylindrical or slightly conical spray pattern and is particularly suited for use in a vertical orientation with the tip facing upwardly or in horizontal orientations. Titanium alloy bolts are used to clamp the front and rear sections of the atomizer together resulting in significant energy reduction and essentially eliminating bolt shearing.

  • Patent number: 4654019
    Abstract: A new toy is provided which, because its topology is that of an inverted toroid, can present multiple appearances and can rapidly change appearances. The toy may be continually manipulated, in a motion similar to turning a pair of socks inside-out, to present a new surface and thus a new appearance with each such action. In a preferred embodiment, the toy is composed of several segments of cloth with elastic and two cloth tabs with grommets at each junction of two segments. The outer surface of the toy is typically formed by a single segment of the cloth with the other segments enclosed. When the segments are distinguished from one another such that each has a different appearance, manipulating the toy so as to bring another segment to the outer surface causes the toy to present a new appearance. Two constraining loops, each going through a set of the aforementioned grommets, act to limit the overall exterior dimension of the toy and facilitate smooth functioning of the toy.

  • Patent number: 4622627
    Abstract: Electrical switching power supply for microprocessors and the like comprising a high voltage d.c. source (30, 34, 32, 50) resonant circuit (38, 51, 42, 52) including a switching transistor (52) which is operated in Megahertz range and provides pulses, via a transformer (40), rectifier (56), smoothing choke (62) to a d.c. low voltage output terminal (66). The rate of switching is controlled by a pulse generator (54) which pulses variably in response to output voltage to thereby vary switching repetition rate and hold to a predetermined output voltage. The inductive elements use spirals (12A and 12A') of thin lines on the surface of a substrate board and ferrite plugs (20) passing through holes (22) in the board to provide miniature inductive elements built into the substrate for effective use in a microprocessor power supply, or the like, and in other applications.

  • Patent number: 4591482
    Abstract: Pressure assisted sintering achieves full densification in short sinter times with low grain growth. This result is enabled by a stage of sintering to a condition of closed porosity (14) followed by a pressure assisted sinter (PAS) stage (16) carried out at a temperature close to, but just below, sinter temperature. Advantageously a small melt formation is induced by a brief temperature spiking (18) during the PAS stage to enable collapse of voids.
