Abstract: A rapid test apparatus, system, and method of use utilizing lateral flow immunoassay (LFIA) detection of a selected ligand in a liquid sample from a body fluid such as saliva in a pet in which antibodies and their complimentary antigens are used with detection-nanoparticles to provide a visual or measurable end point indicator in which the method measures the exposure to viruses in the canine from Canine Parvovirus (CPV) and/or Canine Distemper virus (CDV).

Abstract: A method for mass rearing of insects. A web including a plurality of wells is provided. Insect eggs or larvae and growth medium are loaded in the wells. The wells are covered. The web is rolled up. The eggs or larvae are incubated during eggs hatch and larval growth. The web is unrolled and the larvae harvested.

Abstract: A method for increasing the floccule size and volume of alumina trihydrate during the Bayer processing of bauxite ore using a flocculant in conjunction with a water continuous polymer. The addition of the flocculant and the water continuous polymer to the alumina trihydrate slurry following the security filtration and settling producing trihydrate that is put through the calcination process to produce purified alumina or used as seed for the precipitation process.

Abstract: An apparatus for calibrating an acoustic sensor. The apparatus includes a transmission material having an acoustic impedance approximately matching the acoustic impedance of the actual acoustic medium existing when the acoustic sensor is applied in actual in-service conditions. An elastic container holds the transmission material. A first sensor is coupled to the container at a first location on the container and a second sensor coupled to the container at a second location on the container, the second location being different from the first location. A sound producing device is coupled to the container and transmits acoustic signals inside the container.

Abstract: In the Bayer process for producing alumina from bauxite of the type wherein the bauxite is added to a caustic solution to produce a soluble aluminate solution and an insoluble red mud fraction which is then subjected to one or more separation steps to produce a thickener overflow which is then subjected to a Kelly Filter Press to polish the thickener overflow the improvement which comprises treating the thickener overflow and the filter aid with a filtration improving amount of dextran.

Abstract: A flexible toy wand having a battery case at its lower end which also serves as the handle of the wand and a decorative lightable end piece at the tip of the wand. The wand is waved in a darkened area and various paths of light are created by the movement of the lighted end piece.

Abstract: A method and composition for producing a more coarse alumina trihydrate crystal in a Bayer process pregnant liquor, involving the addition of approximately 5-400 mg/l of surfactant-oil, the oil dissolving the surfactant which can be selected from a host of surfactants which are stable in (hot) caustic solutions and capable of dispersing hydrophobic liquids in the Bayer liquor. The preferred embodiment involves the use of tall-oil fatty acids; a number of equivalent surfactants are established. The oil or hydrocarbon (hydrophobic) liquid can be selected from paraffinic oils, naphthenic oils, mineral seal oils, fuel oils, and bottoms or residue from a C.sub.10 alcohol distillation.

Abstract: An apparatus and a method is disclosed for correcting on-line error corrections in the digital transmission of voice or data utilizing forward error correction technique which avoids on-line calculations of the Massey or Berlekamp algorithms and the Chien search that it entails, and permits a simple hardware apparatus comprised of a ROM, shift registers, and exclusive OR gates, thus eliminating the requirement of a dedicated massive computer.

Abstract: An indicator for recording the load at which a fatigue specimen breaks during the last cycle of a fatigue test. A load cell is attached to the specimen which is alternately subjected to tension and compression loads. The output of the load cell which is proportional to the load on the specimen is applied to the input of a peak detector. Each time that the specimen is subjected to a compression load, means are provided for appyling a positive voltage to the reset of the peak detector to reset it. Hence, during the last cycle of the tension load the peak detector measures the maximum load on the specimen. Means are also provided for disconnecting the load cell from the peak detector when there is a failure in the specimen.

Abstract: An automatic printed circuit board tester to test printed circuit boards and diagnose faults in digital and analog electrical circuit networks is disclosed. The system is comprised of control, stimuli, and interconnection networks in combination with measuring instrumentation. For automated fault isolation, a moving probe assembly driven by stepping motors controlled by a minicomputer is utilized. The fault isolation system establishes a fault path from an output pin to a terminal point within the network. The location of the terminal point together with a directed graph is utilized to select branches that could cause the failure.
