Abstract: Liquid, such as milk, enters the sealed container from an inlet at the top of the container and exits through an outlet at the bottom of the container. The quantity of liquid in the container is sensed and a microprocessor calculates the total volume of liquid. During periods of low flow, such as at the beginning and at the end of the milking cycle, the outlet is automatically closed, partially or completely, by a motorized valve connected to the microprocessor, or by a weighted float situated within the container, so as to accumulate the liquid during those periods thereby enhancing the accuracy of the measurement.

Abstract: The software based interactive system provides accessibility to an institution's own policies via either an internet web site or an intranet home page. Qualified users may search for and access documents related to institution policies for review, including a list of those which the user is required to know. Where required, a test is provided to the user. The responses are scored and the results stored. Administrative users can set and change qualification parameters as to individual, group and/or institution-wide policy access and receive individual, group and/or institution-wide test results. Identification of incomplete, contradictory or obsolete policies, policies awaiting approval, policies due for review and data on user review of policies can be reported.

Abstract: Building bricks and tiles are made by mixing 60% to 75% clay, 20% to 40% sludge and 1% to 10% sand, all percentages being by weight of the total composition. This process utilizes industrial waste products to provide building materials which are lighter and stronger than conventional materials.

Abstract: An advertising display unit has a blind wound between a pair of spaced rollers rotatably mounted for bringing a selected portion of the blind into a display window area. A mechanism for longitudinally moving the blind is provided which is easily accessed and actuated manually. Each roller comprises an assembly having a larger diameter portion onto which the blind is wound and a smaller diameter portion that rotates with it. A cord drive is secured to and wound a number of turns round the smaller diameter portion of one roller. The cord drive follows a path a section of which extends externally of a housing in which the rollers are mounted. The cord drive passes to the other roller where it is wound a number of turns about and secured to the small diameter portion of the other roller. The cord is wound about the small diameter portion so as to wind off one and onto the other with the rollers rotating in the same direction. The blind serves to transmit drive from the wind-up roller to the wind-off roller.

Abstract: The container includes a first chamber connected to the liquid source through an inlet port of a given cross-sectional area and a second chamber connected to a drain through an outlet port of at least equal size. The chambers are separated by a partition having a slot which has an elongated portion extending from the container floor in a direction generally parallel to the container side walls. The area of the elongated slot portion is approximately equal to the area of the inlet port. Liquid level or weight sensors generate signals representative of the quantity of the liquid level in the first chamber to a microprocessor to measure the flow rate. The signals are integrated over time to measure the total volume.

Abstract: A plurality of fasteners are arranged along opposite edges of the shower curtain. Each fastener includes a mounting strip with a body portion which carries a pair of integral suction cups. The strip is heat sealed to the curtain material. In particular, a peripheral edge, thinner than the body portion, is formed during the heat sealing process. A passage or opening through the body portion acts as a guide during the heat sealing process and permits air trapped during sealing or water trapped during use to escape from behind the mounting strip.

Abstract: The clip-on sunglass assembly mounts on eyeglasses and has mirror image frame parts. Each includes a lens retaining frame portion with a set of protruding “L” shaped eyeglass engaging prongs and a bridge element. A mechanism is provided for connecting the bridge elements for movement between a proximate position, where the frame parts are relatively close to each other, and a remote position, where the frame parts are relatively far from each other. The connecting mechanism includes at least one coil spring situated within a cylindrical enclosure. The frame parts are normally biased toward each other by the spring such that the prongs securely engage the eyeglass frame. In one preferred embodiment, the enclosure has an open end which receives the bridge element of one frame part. The spring is operably situated between the enlarged end of the bridge element and the interior wall of the enclosure, adjacent the open end.

Abstract: The simultaneous synthesis of diverse organic compounds is performed in stackable modules which are moveable among nesting sites located on work station platforms. The reactor module includes a heat transfer block adapted to receive an array of reactor vessels, preferrably in the form of solid phase extraction cartridges without sorbent, each with an outlet port. A plurality of valves are located below the vessels. The valves consist of rows of gang-controlled stopcocks which regulate the passage of fluids from the reactor vessel outlet ports into aligned channels, each formed by a pair of threated Leur tip adapters. The reactor module may be situated over a discharge module. The inlet openings in the discharge module accept the threaded ends of the Leur tip adapters. The discharge module may consist of a multi-well collector block or a drain block. An introduction module, which includes a pressure plate having an array of openings and a septum, may be received over the reactor module.

Abstract: The simultaneous synthesis of diverse organic compounds is performed in stackable modules which are moveable among nesting sites located on work station platform. The reactor module includes a block adapted to receive an array of tube-like reactor vessels. The vessels are sized to optionally accept porus polyethelyene microcannisters with radio frequency transmitter tags. Each vessel has a bottom port connected to an outlet tube. A valve block located below the reactor vessels simultaneously controls discharge through the outlet tubes. The valves block includes plates with aligned, relatively moveable sets of rib surfaces which act through Teflon encapsulated silicone O-ring cord sections to simultaneously close rows of outlet tubes.

Abstract: The clip includes a base to which a bistable sunglass lens carrying frame is mounted. The frame is moveable relative to the base between operative and inoperative positions. A “U” shaped spring biases the frame toward each position. First and second parts are mounted on the base for rotation in parallel plans, about a common axis perpendicular to the base, such that clamping arms extending from each of the parts are moved relative to clamping arms fixed to the base, between a position in which the clamping arms are proximate to each other and the eyeglasses are securely clamped therebetween, and a position in which the clamping arms are remote from each other. The spring also biases the parts toward the clamping position. The components are easily assembled, being held together by a single conventional fastener, in the form of a screw or a press-fit pin.

Abstract: Transient voltage suppressor semiconductor devices and other semiconductor devices having rigorous requirements for the diffusion and depth of impurities to produce P-N junctions can be fabricated at surprisingly low costs without sacrifice of functional characteristics by subjecting the substrate to a grinding process resulting in a surface short of polishing perfection, thereby to eliminate the time-consuming and hence costly conventional polishing operation, and then diffusing the desired impurity into the substrate from a solid impurity source.

Abstract: The handle has a blade mounting portion with a raised boss forming a slot. The blade has a boss receiving recess with a portion defined by an edge. The cartridge has a transparent top so that the presence of a blade within the cartridge can be observed and an opening at one end into which the blade mounting portion of the handle can be inserted. The bottom of the cartridge includes a spring platform with a recess into which the blade is received. The platform is integral with the cartridge bottom and is mounted in cantilever-like fashion, by a living hinge, to permit it to flex. When the top and bottom of the cartridge are assembled, ribs on the top cause the platform to move to a spring loaded position, where the forward end of the handle boss can enter the blade recess. As the blade mounting portion of the handle is inserted further into the cartridge, the flexibility of the platform permits the boss to be fully seated within the recess, mounting the blade on the handle.
