A device is provided for preventing accidental locking of the steering shaft of a motor vehicle of the type having an ignition lock, operable by rotation of an ignition key. A locking bolt, which is engageable with the steering shaft only upon the rotation of the ignition lock to ignition-off position, and withdrawal of the key from the ignition lock, is prevented from engaging the steering shaft during the running of the vehicle by means which is electrically actuated and which will permit with...

A method of treating or preventing coccidiosis in poultry which comprises orally administering to poultry an effective coccidiosis treatment or preventing amount of a compound of the Formula (I) or a pharmacologically acceptable acid addition salt thereof wherein R and R' are the same or different and each is a hydrogen atom, loweralkyl, cyclohexyl, benzyl, phenyl, halogen substituted phenyl, or loweralkoxyloweralkyl, R.sup.2 is lower alkyl and n has an integral value from 1 to 8. A composition ...

This valve is constructed of a multiplicity of molded parts joined by a variable number of bolts into a body with an inlet passage opening to an intermediate chamber via an inlet check valve with wedging sealing action; with the intermediate chamber opening to an outlet passage via an outlet check valve with wedging sealing action; with a diaphragm chamber having a diaphragm therein to divide the chamber into an inlet pressure portion opening to the inlet passage via a interconnecting passage, a...

A device for preventing meandering or free running of a web on a roll supported on a shaft on a machine, like a thermal printer. A stationary shaft is fixed to the frame. A core is rotatably mounted around the shaft. A reel mounted around the core has a carbon ribbon that is to be wound on it or unwound from it when the reel is rotated. A leaf spring between the core and the inner circumference of the reel frictionally connects the reel and the core so that the reel does not rotate idly of the c...

A corrosion-preventing structure for protecting reinforcing bars in reinforced concrete from corrosion. This corrosion-preventing structure comprises an adhesive layer, a swelling agent layer with a water-absorbing polymer blended therein, and a protective cover layer which layers are successively formed onto the surface of the reinforced concrete to be protected from corrosion.

A wheel lock prevention apparatus for use in a motor vehicle includes a main passage connected between a master cylinder and a brake unit for transmitting a brake fluid pressure, a first normally-open solenoid-operated valve disposed in the main passage, a reservoir mechanism for storing a brake fluid, a second normally-closed solenoid-operated valve having one end connected to the main passage between the brake unit and the first normally-open solenoid-operated valve and an opposite end to the ...

A toilet backflow preventing valve and toilet bowl support for mounting between a standard soil pipe mounting flange and drain horn of a standard toilet bowl supports the toilet bowl closely adjacent the floor level, receives standard toilet bolts clamping the valve between the toilet bowl and the soil pipe and has a manually actuated slide with an open position that does not obstruct flow and a closed position sealing the soil pipe to prevent blackflow into the toilet bowl. A feature includes O...

A method of preventing "compromising radiation" when processing and transmitting secret data information in data processing and long-distance data transmission systems. In addition to direct, physical shielding and/or decoupling of the data signals, a code converter of per se known construction is employed which acts indirectly in the plane of the logic processing or coding of the information and which additionally processes the secret data in such a manner that at any point in time during furth...

A theft preventing device comprising a lock body, a cable member having one end fixed to the lock body and the other end fastenable to the lock body to bring the device into a locking position, and an alarm system contained in the lock body. The alarm system includes an alarm device, a drive circuit for the alarm device, and an inhibiting circuit for the drive circuit. The inhibiting circuit is completed by means of a light-conducting member extending through and along the cable member. Maximize...

A device for preventing error or misreading in a marine compass fastened to a sloping plane, the compass being provided with a pendulum (9) mounted for limited pivoting movement inside its spherical casing (1), the pendulum having rotatably and pivotably mounted on it a compass disk (16) with a scale (18), which is intended to be read against a co-called steering line (12) on the pendulum (9) at an angle of 0.degree. to about 45.degree. relative the horizontal plane. The pendulum is pivotably mo...
