Abstract:

In a mechanical cell for blending elastomer particles and solution into uniform mixtures, a solid core with an entrance surface, an exit surface spaced apart from and substantially parallel to the entrance surface, and a plurality of minute core passageways therebetween for flow of an elastomer-containing hydrocarbon solution from the entrance surface to the exit surface, the passageways have a characteristic dimension of predetermined size to reduce globules of elastomer to small particles distributed evenly in liquid hydrocarbon solution without plugging the passageways. Typically the passageways have a characteristic dimension of predetermined size to reduce globules of elastomer selected from the group consisting of natural rubber, styrene-butadiene rubber, polybutadiene rubber, polyisoprene, a nitrile rubber, and a copolymer of a 1,4-conjugated diene and a vinyl aromatic monomer, to small particles distributed evenly in liquid hydrocarbon solution comprising a vinyl aromatic monomer. Preferably the passageways have a characteristic dimension of predetermined size to reduce globules of elastomer to small particles having diameters in a range downward from about 200 micrometers.

International Classification:

B01L 300
G01N 2101

US Classification:

422 99

Abstract:

A diagnostic testing device is disclosed. The testing device includes a base member and a cover member which defines an opening for the reception of a liquid specimen. A distribution wheel delivers portions of the specimen to antibiotic units which are circumferentially spaced. Indicator units are in communication with the cover member. A delivery cylinder extends upwardly from each of the antibiotic units toward a respective one of the indicator units. Relative vertical movement between the delivery cylinder and the indicator unit places the cylinder and the indicator unit into an engaging relationship. A change in coloration at an indicator unit indicates a positive reaction.

Abstract:

A device for performing agglutination immunoassay reactions and the like is disclosed. The device includes a first hydrophilic layer, a second liquid-occlusive layer parallel to and overlying the first layer, and a third layer parallel to and overlying the second layer. The third layer has a transparent opening for observing particles. The second layer is interposed between and in adherent relationship to the first and third layers. The second layer has at least one slot defining a channel for directing liquid conducted by capillary action through the chamber defined in conjunction with the first and third layers. This chamber has a proximate zone and a distal zone. The geometry of the chamber is modified to provide preferably outwardly diverging walls and provide a flowpath having different rates of flow per unit area along the paths. This arrangement of different paths in the chamber allows agglutination reactions in the chamber to result in the formation of a non-random pattern of aggregated particles in the distal zone of the chamber. Such a non-random pattern is more readily observable than a random pattern of aggregated particles.

International Classification:

H01R 1101

US Classification:

439210

Abstract:

A wiring harness is disclosed for deploying electrical wires along a wall such as in a modular wall panel system for separating work areas. The wall has an elongate compartment defining a raceway for housing the wires. A first power block is positioned in the raceway at a first location and includes a given number of wires extending therefrom into the raceway. A second power block is positioned in the raceway at a second location longitudinally spaced from the first power block. The second power block has a different number of wires extending therefrom into the raceway toward the first power block. Splicing connectors electrically couple at least some of the wires between the two power blocks.

US Classification:

439596

Abstract:

A cable tap system is disclosed for selectively connecting a plurality of tap terminals to a plurality of conductors in either a continuous multi-conductor electrical cable or in two ends of two such cables butt up to one another. A closable cable clamp assembly clamps onto the continuous cable or cable ends. A terminal holder is positionable against one side of the cable clamp assembly and mounts a plurality of tap terminals for interconnection to the conductors of the cable. A backing member is positionable against an opposite side of the cable clamp assembly. A plurality of rotatable fasteners are operatively associated between the terminal holder and the backing member for sandwiching the cable clamp assembly therebetween and maintaining the tap terminals interconnected with the conductors of the cable. A tool is provided for simultaneously rotating the fasteners to close the terminal holder and the backing member in a uniform action.

US Classification:

422 73

Abstract:

An improved device for performing agglutination reactions is disclosed. The device has at least one chamber with a proximate zone and a distal zone in which chamber agglutination reactions can be performed. The improvement comprises utilization in the device of a layer of liquid absorbent material for controlling overall rate of liquid flow through the chamber. The layer of liquid absorbent material is selectively impregnated with a substance to form an impregnated region and a non-impregnated region wherein the non-impregnated region is liquid absorbent and the impregnated region is liquid-occlusive. A portion of the non-impregnated region is positioned within the distal zone of the chamber so that the non-impregnated region is in liquid communication with that zone.

US Classification:

439107

Abstract:

An electrical connector assembly includes a pair of spaced receptacle modules mounted to a first printed circuit board which is electrically coupled to a second printed circuit board spaced from and generally parallel to the first printed circuit board. A conductive ground plate is electrically coupled between the printed circuit boards and mechanically supports the circuit boards in their spaced generally parallel relationship. The ground plate is disposed perpendicular to the first and second printed circuit boards forming two separate compartments between the first and second printed circuit boards to provide electromagnetic interference isolation between the compartments. An electrical component such as transformer may be mounted on one side of the ground plate between the spaced generally parallel printed circuit boards, and the ground plate provides a heat sink for the transformer. A third printed circuit board may be mounted on the side of the ground plate opposite the transformer and electrically coupled to the transformer through the ground plate.
