A strain meter includes first and second blocks clamped to a rotating shaft with a linear variable differential transformer (LVDT) rigidly affixed to the first block and a displacement arm rigidly affixed to the second block. A LVDT core is attached to one end of the displacement arm and disposed to be movable without contact through the center of the LVDT. A flexible cable is connected between the displacement arm and the LVDT to control the radial position of the LVDT core. A vertical stabiliz...

A strain relief for electrical cords wherein the flexible characteristics of the end of the tail portion are improved.

A strain multiplier is provided which is designed to be firmly attached to both a structural surface and a sensing gage at all points of contact between the multiplier and the structural surface and the multiplier and the sensing gage while preventing direct contact between the sensing gage and the structural surface.

In an improved strain gage for measuring pressure differentials within areas of varying pressure there is provided a flexible sapphire diaphragm having disposed thereon a Wheatstone bridge. The diaphragm being attached to a base portion by way of a glass bonding material. The base portion's function being to support the flexible diaphragm without interfering with the measurement of strain. The diaphragm having a recess extending to a predetermined depth thereby defining a recessed area having a ...

A strain gauge comprised of a premagnetized ferromagnetic film wherein any change in length of the film is converted into a planar Hall voltage by employing the property of magnetostriction and the planar Hall effect. Alternately, a change in the length of the film can also be measured as a change in electric conductivity by employing the properties of magnetostriction and magnetoresistance. The strain gauge is deposited on a substrate by thin-film techniques and has a very high sensitivity.

A strain gauge has two metallic resistance layers, contact layers associated therewith, and a support for holding the strain gauge. A partially conductive insulation layer is disposed between the two resistance layers.

A one-piece plastic strain relief bushing for power line cords comprises a main body portion with a pivoted locking portion at one end thereof. The main body portion includes spaced-apart parallel walls which grip the line cord such that the line cord in the bushing is in a predetermined serpentine path. The pivoted locking portion snaps fits with an end section of the main body portion to form a slot which completely circumscribes the line cord.

A strain gauge or transducer is provided incorporating a supported film electrical resistance element whose electrical resistance varies as a function of applied mechanical strain and is provided with electrically conductive terminals. The resistance element comprises a dispersion of electrically conductive or resistive particles in an organic polymer together with an optional electrically insulating filler material. In a particular embodiment, the resistance element is supported on a member of ...

A new device and method for providing strain relief to a cable including a base with a tubular extension, the tubular extension having a plurality of deflectable arms, each of which are radially converged and constricted about a cable under a compression force caused by the tightening of a nut having a tapered region formed in an inner nut channel.

The novel strain JHCC 4279 of Bacillus thuringiensis and insecticidal compositions containing insecticidal protein endotoxin produced by the strain JHCC 4279 which protects plants from Diabrotica by exposing larvae to the insecticidal protein endotoxin produced by the strain. Novel genes for insecticidal proteins may be isolated from strain JHCC 4279.
