  • Patent number: 3991912
    Abstract: A package includes a sealed collapsible container of puncturable film material with liquid contents. One portion of the container is formed into a pocket. The container is also provided with structure for attachable receiving a dispenser which is adapted to be secured to the receiving structure. The dispenser may be a cannula with an insert or penetration conduit. When the insert conduit is placed in the pocket and forced to penetrate the innermost portion thereof, the body of the dispenser is secured to the receiving structure of the container. Pressure may be applied to the container and contents to dispense the contents through the attached cannula; and this pressure forces the inner folds of the gusset into progressive sealing engagement with the insert conduit of the cannula to prevent spillage or seepage of the liquid contents.

  • Patent number: 3988541
    Abstract: The inherent dependency upon frequency of the response of an electro-mechanical transducer is compensated over a wide frequency range by driving the transducer with a current source, the signal of which is modified to have a frequency characteristic which is the complement of the frequency characteristic of the mechanical response parameters of the transducer.

  • Patent number: 3987788
    Abstract: A thermistor is used to sense the temperature of blood at a location downstream of a point at which a small quantity of liquid (indicator) having a temperature lower than the blood is introduced. Circuitry is used to compute the flow measurement from the sensed blood temperature according to the Stewart-Hamilton dilution equation for a thermal indicator. Values are manually entered into the system for a computation constant, the temperature of the body and the temperature of the indicator. The thermodilution curve sensed by the thermistor is integrated through the peak value to a predetermined per cent of the peak value and increased by a predetermined per cent to generate an estimated integral value. The flow value is computed in a dual slope ratiometric analog-to-digital converter by taking the ratio of the product of the temperature difference times the computation constant to the estimated integral value.

  • Patent number: 3982364
    Abstract: A floor structure includes a plurality of height-adjustable ground pad or anchor assemblies which either rest on or are embedded in the ground and which are laid out to define a grid. The top of each ground pad and anchor assembly is provided with a casting which includes laterally extending support flanges to which floor panel receivers are pinned to the ground pads and anchor assemblies along the grid pattern. The floor panel receivers include elongated horizontal channels, open at the top for receiving tongues on the peripheral framework of individual floor panels. Floor joints fill the openings between panels. A separate peripheral wall support base provides a channel for receiving a wall panel, and it is tied to the ground pads or anchors.

  • Patent number: 3977394
    Abstract: A programmable digital computer receives an electrical signal from a spirometer into which a person under test breathes. The signal is representative of the volume of air expired by the person. The computer controls a matrix printer. Data may be entered into the computer via a keyboard. The computer instructs the operator as to when identification data may be entered via the keyboard. The operator indicates which test is to be conducted by actuating the keyboard; and the computer receives the data and indicates whether acquired test data is acceptable. The operator tells the test subject which breathing maneuver he must follow for a desired test. The computer stores the test results and the operator may then have the measurement test results analyzed by the computer, compared with standardized predicted values, and printed on a permanent record.

  • Patent number: 3977432
    Abstract: An improved oxygen mask, particularly useful for treating patients requiring inhalation therapy, wherein the extent of oxygen dilution with room air may be selectively controlled to provide different predetermined oxygen concentrations. The diluter is interposed in the line between the inlet hose of the mask and the oxygen supply tube and essentially comprises two closely-fitting parts: a tapered tubular body which houses an integral ejector nozzle, and a tapered tubular sleeve which is fitted upon the body for rotational movement into any of a plurality of selected positions but is securely locked against axial movement upon that body. The parts have apertures which are moved into or out of alignment as the sleeve is rotated into different angular positions of adjustment. An aerosol adapter may be removably mounted upon a projecting end portion of the body for directing vapors towards the inlet apertures of the diluter.
