  • Patent number: 5193547
    Abstract: A system for monitoring physiological conditions in humans and other animals includes a transducer for monitoring such conditions as blood pressure, a monitor for displaying or recording signals from such transducers, or both, and a connector for linking the transducer to the monitor and for transforming the impedance level of signals from such transducer to levels appropriate for such monitors and for drawing and adapting power from the monitor for effecting this impedance transformation. The connector may also include a mechanism for adjusting the offset or sensitivity of the signal from the transducer, a mechanism for detecting the absence of the transducer, and a mechanism for detecting an open circuit between the monitor and the transducer.

  • Patent number: 4720351
    Abstract: The invention relates generally to products useful for home laundering, and more particularly to a product which incorporates a prespotter with a detergent and having one or more of the following separate functions: detergency, fabric softening, stain removal, bleaching, and bluing; with the advantage being that both the detergent and the prespotter are uniquely packaged together as one product, negating the need to purchase and store separate products for each end use function, and also, unavoidably providing presentation of the prespotter to the detergent user at the time of laundering. The invention also concerns methods of use of such products during laundering.

  • Patent number: 4667818
    Abstract: An adapter is provided in the form of a holder into which a fitment dispenser is removably received; the adapter is removably mounted on the neck of a capped container for removably suspending the dispenser within that neck. The adapter typically has frictional interfit with the dispenser which may be tubular. The container typically contains a first composition, and the fitment dispenser typically contains a second composition which is to be dispensed at the time access is gained to the first composition in the container via its neck, for use in cleaning process.

  • Patent number: 4648868
    Abstract: An apparatus comprising a valve body having first, second and vent ports and a generally tubular valve element having a peripheral wall with first, second and vent openings in the peripheral wall leading to the interior of the tubular valve element. The valve element is mounted in the valve body for rotational movement between first and second rotational positions and for axial movement between first and second axial positions. A pressure sensor is exposed to the fluid pressure within the valve body. In the first rotational position of the valve element, drip flow is provided between the first and second ports, and in the second rotational position, the vent port is open to provide communication between the pressure sensor and the atmosphere. To provide flush flow between the first and second ports, the valve element is moved to the second axial position.

  • Patent number: 4606775
    Abstract: The method of washing articles in an automatic dishwasher includes the steps:(a) providing a first volume of a first treating component for use in the dishwasher,(b) providing a second volume of a second treating component in close transported association with the first volume, but isolated therefrom, for presentation at the time of use of said first component,(c) one of said first and second components consisting essentially of nonionic surfactant, and the other of said first and second components consisting essentially of chlorine release agent, and(d) separating some of said second component from said close association with the first component and employing same in the dishwasher at the time of adding said first component to the dishwasher.
