Apparatus for preventing accumulation of strip between stands of a multistand hot or cold reduction mill when a strip breaks includes a curved knife blade of greater width than the strip, means for maintaining the knife in a stand-by position above the path of the strip, and means for moving the knife into contact with the strip to cut and reverse the direction of travel of the strip. The method consists of detecting the strip break, actuating a cutting means, cutting the strip and reversing the...

A microwave oven comprising a door lock key operatively associated with a door handle of a door hermetically sealed to block off the escape of microwave energy, and a door lock switch operated by said door lock key, whereby instantaneous leakage of microwave energy is prevented when said door is opened in the course of heating.

A rust preventive coating composition having a long pot life and providing a coating in which generation of white rust is greatly reduced, said coating composition being obtained by incorporating a small amount of at least one salt selected from the group consisting of molybdate salts, tungstate salts, phosphomolybdate salts and phosphotungstate salts into a coating composition comprising as main components an alkali metal silicate or ammonium silicate and zinc powder.

A concurrent entry preventing system for use in electronic calculating machines capable of preventing the erroneous arithmetic operation performed by the calculating machine. To this end, means is provided for yielding a warning signal indicative of the fact that two or more character keys are concurrently operated in a wrong course. This warning signal comprises the logical product of a signal indicative of operation of one of such characters by a signal indicative of operation of one or more o...

A system for preventing collision wherein a radar system is mounted on a vehicle for generating a relative speed signal and a relative distance signal. There are provided a brake signal generating logical circuit responsive to the relative speed signal and the relative distance signal for actuating a brake actuator, first and second comparators for comparing the relative speed signal and the relative distance signal respectively with reference signals, and an information processing signal respon...

Deposition of ammonium chloride from a gaseous stream as it is passed through a compression means is prevented by recycling to the compression suction a sufficient amount of the compression means discharge that has been heated by the compression operation to maintain the temperature of the gaseous stream above the deposition temperature for ammonium chloride at operating pressure. The invention is particularly useful in hydrocarbon hydrogen treating processes in which hydrogen recycle streams co...

A catheter for the administration of fluids into the body which includes a length of precurved, flexible tubing permanently attached to a gripping member having a winglike structure projecting therefrom. A catheter assembly comprising a catheter having a precurved distal portion and a gripping member permanently attached thereto, an introducer needle disposed partially in the catheter and a sleeve slidably disposed over the catheter tubing, the sleeve being operable to prevent internal skiving o...

An elastic strap for preventing neck injuries used in combination with a head piece and a body harness has fastening members thereon for engagement to a securing member on the head piece and on the body harness to limit the forward movement of the head piece.

A foam-preventing device for automobile hydraulic power units, comprising an intermediate pressure chamber located between an oil tank of the unit and the outlet of a flow-rate control valve of the unit for by-passing excess oil to the oil tank. Excess oil is forced by this arrangement to flow through the intermediate chamber so as to avoid a sudden pressure change and foaming thereof.

A cable to be straightened passes through a rotatably supported split cylinder formed with spiral grooves for mating relationship with the cable. The rotatable cylinder resides within a bearing block that resides in a support block. By pressing opposed support blocks together, pressure may be applied to the cable for straightening it as it translates through the split cylinder to cause the split cylinder to rotate and thereby help prevent kinking of the cable.
