Nucleic acid fragment capable of hybridizing to rRNA of Listeria monocytogenes and not to rRNA of Bacillus subtilis.

A test fixture for testing a specimen under compressive or tensile load under close, reproducible tolerances and conditions. Confronting platens having surfaces which act against the specimen are provided with an in-line wedge assembly which drives the platens to load the specimen. The platens and wedge assembly are positioned between the top and base of a frame assembly. The top and base are connected by side plate members which are tensioned when the wedge assembly is operated to load the spec...

A test support including an undercarriage and an opening formed therein which is dimensioned for a turret or the like comprises a combat space container interchangeably accommodated in said opening. The combat space container comprises a cage which is detachably joined to said undercarriage, and a roof which is detachably joined to the cage. The cage carries largely invariant components and/or equipment, while the roof carries components and/or equipment which is to be varied more frequently.

A test kit for preparing a chemical test pad used in testing for the presence of occult blood in a specimen. The test kit is a foil package enclosing an absorbant pad bearing a peroxygen agent and a solution of guaiac in alcohol in a separate packet or compartment from the absorbant pad. The separate packet or compartment being rupturable by applying hand pressure to the outside of the foil package to mix the peroxygen agent powder on the test pad and the guaiac solution prior to removing the ab...

A test station for use in evaluating semiconductor chips and the like. The test station has improved components for supporting and adjusting the positions of a microscope and stage relative to a base surface which supports a plurality of probes.

A station for testing electrical devices under elevated and depressed temperature conditions, said devices being transported through and tested in the station while held in coordinated planar sets. The planarly arranged sets of devices are sequentially placed upon a platen movable along three mutually orthogonal axes. A test head has a plurality of electrical device contactors in planar arrangement corresponding to the arrangement of the devices sets. At least one axis along which the platen mov...

This disclosure illustrates and describes a test mold for the quantitative measure of the effects of formulation and/or process variable changes on some kinds of surface problems of a molded part caused by different degrees of imperfection or voiding underneath the part surface. The molded part can be single component or composite, solid or foamed. One example of the surface problem is the so-called "measles or cellulite" problem observed on the vinyl surface of a vinyl/foam composite due to the...

A wire distribution apparatus is disclosed and includes a wire termination module having a cross connect field and a protector field electrically wired to the cross connect field. The cross connect field includes a plurality of electrical contact points arranged in a predetermined array. A test member is provided for accessing test equipment to test signals carried by conductors connected to the cross connect field. The test member includes a housing which is releasably attachable to the module ...

A high pressure fitting for placing on a tubing includes an annular sleeve having sealing rings therein and a collar enclosing a portion of the sleeve to restrain lateral movements of the sleeve with respect to the tubing. The sleeve has an interior threaded region to receive a plug and an interior annular region. A recess in the annular region retains an O ring and two backup rings which contact the tubing. The sleeve does not contact the tubing. The collar includes two members that have a flan...

The present invention is a test valve plug assembly designed to be installed within a drain tee which connects a tub drainage and overflow system to the drainage system of a building. In its closed position, the test valve plug provides a means for closing the drain tee, thereby permitting the drainage system below the drain tee to be filled with water for testing purposes.
