摘要:
A connector for making electrical connection between an externally jacketed conductive shield on a communication cable and a conductor. The vise-like connector includes a pair of resilient opposed plate-like jaws formed with barbs along tapered projecting portions and adapted to be clamped in engagement with an end of the externally jacketed shield.

NOVEL SUBSTITUTED N-CYANOPHOSPHORUS IMIDES HAVING A RELATIVELY HIGH DEGREE OF HYDRLYTIC STABILITY ARE PREPARED BY REACTING A TRIVALENT PHOSPHORUS COMPOUND WITH DIFLUORODIAZIRINE IN THE PRESENCE OF AN INERT SOLVENT. SUCH COMPOUNDS HAVE UTILITY AS PEST CONTROL AGENTS, CORROSION INHIBITORS, PLASTICIZERS, FLOTATION AGENTS AND PETROLEUM ADDITIVES.
摘要:
A composite film having a flexible heat-resistant base layer, a heat softenable pressure formable adherent intermediate layer, and a conformable upper layer of a magnetic powder oxide dispersed in a non-magnetic binder. The film can be permanently embossed in its upper surface upon pressure contact with a suitable heated die to provide thereon a guide pattern such as a spiral groove, and is thereafter useful as a sound disc.
摘要:
Copy-sheets containing heavy metal azolates, such as silver imidazolates, are imaged by heating with a reducing agent applied in image-forming pattern. Colored images are then produced in base-sensitive copy-sheets by heating the imaged azolate sheet thereagainst.
摘要:
A mechanism for transferring predetermined lengths of pressuresensitive strip adhesive to objects from a supply of strip adhesive carried on a releasable liner. The device includes means for severing the supply of strip adhesive to form a predetermined length of adhesive, for positioning the length of adhesive on an application surface of a pressure foot, for providing relative movement between the pressure foot and a support surface to press the length of adhesive into contact with an object positioned on the support surface, and for transferring the length of adhesive from the liner to the object.
摘要:
A series of graduated-size sphygmomanometer cuffs are provided, each being adapted to be used by encompassing a limb of a size related to such cuff, and each having a distinctive color corresponding to its individual size. Each cuff has a pointer index on an edge of the cuff, and a size index spaced longitudinally from the pointer index and adapted to be in substantial registered relation with the pointer index when the cuff is in limb encompassing position.
摘要:
Electrically conductive adhesive tapes in which the layer of adhesive is made conductive by the inclusion of small, complex metal particles having a low apparent density.
摘要:
A method and a device for internally locating leaks in a pipeline and sealing the leak without interrupting the normal use of the pipe. The device has a tubular rigid body which is open at both ends and is covered on the outside by an inflatable sleeve which can be pressurized to seal off a liquid-tight cavity between the pipe wall and the sleeve surface. The pipe is tested for leaks by pressurizing the cavity with a test liquid and thereafter observing the pressure drop to determine if a leak is present. If a leak is discovered, a settable liquid sealant is forced into the cavity filling the leak.
