| 263 | Data transmission in radiographic apparatus | US942373 | 1978-09-14 | US4181850A | 1980-01-01 | Ian A. Fairbairn |
| In radiographic apparatus in which a source of radiation and detectors receiving the radiation are orbited about a position for locating a patient, the examination can be carried out using a rotation through 360.degree. or more. This arrangement uses slip rings for carrying data, including the output of the detectors and provides a slip ring arrangement suitable for high speed use. The slip rings can have capacitative coupling to avoid data loss if the brushes are allowed to bounce and for use therewith the data should be encoded in a D.C.-component-removing digital code. | ||||||

| 265 | Microwave oven with food temperature-sensing means | US794090 | 1977-05-05 | US4149056A | 1979-04-10 | Tetuya Kaneshiro; Takeshi Tanabe |
| A food temperature-sensing probe is included within a microwave oven for monitoring an internal temperature of the food while it is being cooked therein. A probe jack inserted into a slipping connector transmits a food temperature signal detected by the food temperature-sensing probe to monitor the internal temperature of the food. The slipping connector is arranged on a top wall of the microwave oven cavity. More particularly, on the top wall at the position approximately corresponding to the center of a turntable when a turntable is positioned within the microwave oven. In a preferred form, the connector is so constructed as to permit the rotation of the temperature-sensing probe in unison with the rotation of the turntable. | ||||||
| 266 | Swivel assembly | US852295 | 1977-11-17 | US4142767A | 1979-03-06 | Robert D. Karl; Ian B. Engh; Harry Bennison |
| A multi-product swivel assembly for carrying oil or other cargo and transmitting electrical power and signal currents, between a ship and stationary oil wells or other installations. The swivel assembly includes a non-rotating or stationary unit, a large upper unit that rotates about the stationary unit, and a center unit that rotates with the upper unit and which extends down within the stationary unit. The center unit includes a large vertical cylinder which surrounds a group of vertical pipes carrying inflammable fluids, and a vertical pipe filled with inert gas and surrounding a conduit that carries an electrical cable. In order to repair the upper rotating unit, as to replace one of the muliple seals thereon, bolts can be loosened to separate it from the center rotating unit. When the bolts are loosened, a shoulder on the stationary unit prevents the center unit from dropping, so that during later reassembly, the bolts will lift up the center unit to its rotating position. To permit access to the bottom of the center rotating unit, jacking bolts are turned to allow the lower portion of the stationary unit to drop down until the seals and the like on the center unit are exposed, the stationary unit being lifted back into place by turning the jacking bolts. | ||||||

| 272 | Electrical brush sensor apparatus useful for analog-to-digital converters | US505670 | 1974-09-13 | US3999022A | 1976-12-21 | John Henry Hosemann |
| An analog-to-digital converter or encoder utilizes a combination of a standard photoelectric encoder and improved slow-friction long-lasting brush-type encoder which together with the necessary code conversion circuitry will produce an absolute unambiguous decimal digital readout and a visual display of the readout all contained in a single compact housing which can be mounted in direct association to the object being measured. The encoder circuit also has an internal clutch arrangement whereby the encoder systems can be selectively disconnected from the input to allow the encoder to remain at zero or some other reference point while the relative positions of the encoder and the object whose position is being measured are changed. The unambiguous output is generated by sensing the position of the first order, or least significant readout digit and utilizing the position to selectively control energization of a preselected one of a pair of sensors associated with the next higher order digit both in the same encoder system and between the systems. | ||||||
