Abstract: A user interface for a thermostat that controls a radiator valve can include a user input member that is movable from a home position to a set point increase or decrease position to increase or decrease a set point temperature of the thermostat. In some embodiments, a return mechanism returns the user input member to the home position after being released from one of the set point increase and decrease positions. The user interface can include an indicator panel and controller that controls the indicator panel to provide an indication of when the set point temperature of the thermostat is being adjusted. The user interface can also include a lockout controller that prevents further set point temperature adjustments using the user interface when the set point temperature differs from the environmental temperature by a specified amount.

Abstract: At least one location on a component is to be inspected by performing non-destructive testing. The components to be tested typically include piping and plate materials or a structural component. The components to be tested are typically storage and transmission components. A guided wave probe is installed on the component at the at least one location. A wave is transmitted a along the component. A reflected wave is analyzed to determine if a fault or damage condition exists or if a specific geometric feature, which is unable to be seen visually, is present. A location of the condition is determined based on the analysis. A localized test at the location is performed to determine structural integrity. The location is marked and its respective condition is recorded for follow-up analysis. The follow-up analysis is performed at the location for the respective condition.

Abstract: The assaying apparatus provides a kit in a collection cup for collecting and analyzing a urine sample for drugs or drug metabolites. In one embodiment, a separator member is disposed in the interior of the cup, separating an isolated liquid sample space from the assay regions of the assay strips. Wicking of the urine sample provides a controlled flow to the assay regions of the assay strips. The cup includes a pair of ribs on the interior surface of the cup forming a slot for receiving and retaining the assay strips and the wick assembly. In a second embodiment, collection cup has a cap with assay strips, and a wick mounted to the cap and extending into the liquid sample space of the collection cup when the cap is placed on the cup, for wicking the liquid sample from the interior of the cup to the assay strips. A transparent cover is provided over the assay strips permitting observation of the results of the assays.

Abstract: A prosthetic foot having a spring assembly with an anterior and posterior component, a snubber for limiting the movement of the spring assembly during assembly, and anterior and posterior shock absorbers provided between the components of the spring assembly and snubber. The arrangement of the posterior shock absorber, the spring assembly, and the snubber is such that ambulation results in the generation of a compressive force in the posterior shock absorber during a heel-strike phase and tensile force in the posterior shock absorber during a toe-off phase.

Abstract: A method and apparatus for inserting a part, such as a spool valve, into a bore of a body, such as a transmission valve body. The apparatus includes a gripper tool that holds the part by use of a light vacuum pressure. The gripper tool is attached to a robotic arm that aligns the part with the bore. Once the part is aligned with the bore, a vacuum pressure is created within the bore that is effective to pull the part from the gripper tool and into the bore.

Abstract: A method and apparatus for assembling a part, such as a spool valve into a bore of a body, such as a transmission valve body. A gripper tool attached to a robotic arm supports the spool valve with a light vacuum pressure and maneuvers the spool valve, aligning it with the valve bore. The gripper vacuum is perturbated to allow the valve to be properly aligned with the bore.

Abstract: A device for performance of ligand-receptor assay methods for determining the presence of a liquid. The preferred ligand-receptor pair are antigen-antibody pairs. The device has a membrane having the receptor physically bound to its surface. The membrane is disposed at the top of a body member, and is affixed thereto by means for attaching, which is preferably a cap with a funnel depression. A porous means is disposed below the membrane to absorb liquid. Substantially all of the top surface of the membrane is exposed. The receptor site typically occupies only a portion of the top of the membrane, and in a preferred embodiment, a funnel member releasably attaches to the cap, thereby conveying the sample through only that area of the membrane having the receptor site. The device has a piston means disposed inside the body member, and in air-tight seal with the body member. Means to actuate the piston means are disposed outside the body member.

Abstract: A new apparatus and method for immunoassays. A gold sol bead is held in a funnel member. First antibodies are associated with the gold sol bead. When the sample contacts the gold sol it dissolves the bead. A second antibody is impregnated on an immunosorbent surface. When the dissolved gold sol passes this surface, any antigen already reacted with the first antibody present reacts with the second antibody forming a gold: first antibody: antigen: second antibody: immunosorbent complex. The gold sol acts as the visible label.

Abstract: A device for performance of ligand-receptor assay methods for determining the presence of a ligand. The preferred ligand-receptor pair are antigen-antibody pairs. The device has a membrane having the receptor physically bound to its surface. A closable gap exists between the membrane and an absorbent means. Substantially all of the top surface of the membrane is exposed. The device has a piston means disposed inside the body member, and in air-tight seal with the body member. Means to actuate the piston means are disposed outside the body member. The piston means creates a region of reduced pressure.

Abstract: Method and apparatus for collecting liquid analytical samples for examination, particularly whole urine and blood samples, and reproducibly separating them into two or more fractions. A sample is disposed within such an apparatus, then staining with dye or reacting with reagent as necessary without dislodging or disturbing the sample within the apparatus, or the arrangement of the apparatus itself. A sample can be transferred from the apparatus which serves as a preparation zone, to a separate analysis zone. An apparatus is shown of a type utilizing a container and a petter, said petter provided with an upper portion which enables attachment to the container, a lower retainer portion including a peripheral aperture, the non-apertured portion of which enables wedge-fit thereof into the container, and a body portion connecting the upper petter portion and lower retainer portion.

Abstract: The disclosure teaches a pipette or petter tube and a system using the pipette to obtain reproducible liquid samples of known small volume. The pipette has an elongate body with one end adapted to be removably engaged by an aspiration device and the other end which is closed is adapted to contact a surface. The body has a spherical portion proximate the closed end. At least one aperture penetrates the wall of the spherical portion. When the petter tube is used in conjunction with a hollow tube having a known volume and of such size that the closed end of the pipette contacts the bottom of the tube a quantity of liquid can be aspirated from the tube leaving only a small predetermined volume behind.

Abstract: Cast members are provided with a liner assembly to protect the cast material from corrosion. The liner assembly is formed of a plurality of curved liner sections having integral joining flanges. A resilient compressible gasket is arranged between opposing flanges and is provided with at least one flange receiving slot for receiving the flange of one of said liner sections to facilitate assembly thereof. Fastening means join the opposing flanges to compress the gasket and thereby provide a liquid-tight joint. Integral flanges are provided at the upper and lower ends of the liner sections to receive a sealant which is squeezed out of the seams formed by the mating sections when joined to protect the cast assembly from corrosion. The liner sections are formed of a material which is inert to the corrosive influences.
