  • Patent number: 4203322
    Abstract: In an ultrasonic flowmeter ultrasonic signals are transmitted alternately upstream and downstream of a fluent media whose flow velocity is to be ascertained. The repetition rate at which signals are transmitted is controlled by a voltage controlled oscillator. To increase the sensitivity of the meter, the frequency of the voltage controlled oscillator, which is related to sound speed through the fluent media, is increased.

  • Patent number: 4203673
    Abstract: The inspection of a cylindrical article is accomplished by scanning the surface of the article in a plane transverse to its longitudinal axis with a light beam sequentially reflected from mirrors spaced about the periphery of the article. Light that is reflected or scattered from the article's surface is detected by sensors which are symmetrically positioned on either side of the scanning plane. Intensity variations and time variations of the sensor signals thus produced are processed to extract information concerning the article's surface uniformity, cross sectional shape, longitudinal shape and length as the article is moved along its longitudinal axis through the inspection plane.An apparatus is also described for effecting such a method. The apparatus uses a rotating polygonal mirror scanner, a plurality of fixed mirrors positioned in the scanning plane peripherally around the article to be inspected and annular sensors positioned fore and aft of the scanning plane through which the articles pass.

  • Patent number: 4202204
    Abstract: The coagulation of blood is measured by introducing the blood into an annular gap in a beaker formed between the inner surface of the beaker and a cylindrical member depending into the beaker. The beaker is mounted on the upper end of a rod-like support. A coil arrangement about the lower part of the rod-like support impresses a circular orbiting motion on the support and beaker. Another core associated with the rod-like support measures changes in amplitude of the support produced by the development of fibrin in the blood sample in the annular gap.

  • Patent number: 4202679
    Abstract: An elongate light conductor of circular or other cross-section is continuously produced by depositing, in a vacuum chamber, a powdered glassy (i.e. vitreous or vitrifiable) material upon the upper end of a descending rod of like material while training a stream of doping ions upon the same end. Vitrification may be assisted by an electron beam, also trained upon the powder-receiving rod end, and/or by thermal treatment of the rod leaving the vacuum chamber. The lower end of the rod is softened in a furnace from which a vitreous strand of reduced cross-section is continuously drawn through an orifice and wound upon a mandrel.

  • Patent number: 4202209
    Abstract: A test system and method for in line testing of shock suppressor shut-off valves is provided. Vacuum and fluid canisters are mounted to a backpack that can be carried by maintenance personnel to the operating locations of shock suppressors. The fluid canister contains a fluid for being driven through the shut-off valves of the shock suppressor during testing. Fluid lines interconnect the canisters and the shock suppressor. A valve assembly is disposed within the fluid lines for regulating the rate of flow of the fluid from the fluid canister to the shock suppressor. The system further includes structure disposed within the fluid lines for evacuating the fluid lines and the valve assembly prior to testing of the shut-off valves.

  • Patent number: 4201919
    Abstract: Apparatus for loading a single sheet of X-ray film into a cassette, from a plastic lighttight envelope containing a stack of such sheets, all in a daylight environment. A receiver for holding the envelope containing the sheets includes a clip at the top that holds one end of the envelope and a groove at the bottom into which the lower end of the envelope can be laid. A rod lies in the groove over the envelope, so that when the lower envelope end is cut, no light leaks in. However, when the receiver is placed on a dispenser, the rod can be withdrawn from outside the receiver to open the envelope and allow the stack of film to fall out into the dispenser which can feed one sheet at a time into the cassette.

  • Patent number: RE30276
    Abstract: Stoppers are separated from tubes they close by suspending a stoppered tube by its stopper, placing the suspended tube in a swinging bucket centrifuge, subjecting the suspended tube to centrifugal force.This may be accomplished by adapting a test tube rack to be placed in a centrifuge's swinging bucket type carrier. The rack is a two piece unit having upper and lower members that are separable. The test tubes use stoppers having an enlarged portion with a diameter which exceeds that of the test tube such that the tubes may be suspended from the upper member by their stoppers. The rack has a height which exceeds that of the test tubes such that when the rack with the tubes suspended therein are subjected to centrifugal force, the tubes withdraw from the stoppers. This leaves the stoppers positioned on the upper surface of the upper member. If now the upper member is lifted away, the stoppers are removed leaving the unstoppered test tubes positioned in the lower member of the rack.
