An angle cock having a rotatable cylindrical plug valve carrying a plurality of sealing members each fitted within a double recess on the periphery of the plug. A sealing member is urged by air pressure into a sealing position when the angle cock is in the closed position.

A surgical instrument formed by a handpiece assembly and a removable tool assembly. The handpiece assembly includes a housing having integrally interconnected grip and nose portions which are of tubular construction and are positionally related so that the longitudinal direction of the nose portion extends at an angle of 40.degree. with respect to the longitudinal direction of the grip portion. The grip portion contains first and second removable cartridge units, with one cartridge unit containi...

An angle detector for determining a transducer's angular disposition to a capacitive pickup element. The transducer comprises a pendulum mounted inductive element moving past the capacitive pickup element. The capacitive pickup element divides the inductive element into two parts L.sub.1 and L.sub.2 which form the arms of one side of an a-c bridge. Two networks R.sub.1 and R.sub.2 having a plurality of binary weighted resistors and an equal number of digitally controlled switches for removing re...

A device capable of gauging angles in the full range from 0.degree. to 360.degree.. The angle gauge has a pair of pivotally connected gauging arms. Each gauging arm is formed by a generally radially outwardly extending leg connected at one end to the pivot axis and a radially offset straight edge leg extending generally laterally from the opposite end of the radial leg. A full 360.degree. angle scale is fixed relative to one of the gauging arms coaxially with the pivot axis and extends radially ...

1. For use in a guided missile system of the conical scanning type an angle ating system comprising: A. a first input terminal for receiving a sine wave signal generated by the conical scanning of the seeker antenna in the direction of a target to be tracked, B. a second input terminal for receiving a sine wave reference signal representating the instantaneous position of the scanning device, C. a third input terminal for receiving a sine wave reference signal shifted ninety degrees in phase fro...

Transparent plastic T-square and other devices for performing geometrical and trigonometrical measurements with particular emphasis on trisecting angles and dividing angles into a plurality of equal segments.

An angle valve is provided which is mountable on the exterior of a container having a container valve disposed therein and which includes a valve housing composed of a container-side connecting member having a front face and a channel formed therein opening onto the front face for communication with the container and a loading-side connecting member disposed at an angle to the container-side connecting member, which has a channel formed therethrough and which is capable of communication with a l...

An angle digitizer receives signal representing the sine and cosine of the angle to be digitized. The voltages are fed to orthogonal pairs of input terminals. Between each two input terminals is a set of equivalued resistors to form a resistor ring. At the junction of each pair of resistors is an output terminal. Each pair of output terminals is connected to the input terminals of a signal amplitude comparator which compares the magnitude of the signals at its inputs to give a digital signal in ...

An angle cock has a body provided with a chamber into which opens an inlet port, a delivery port and an exhaust port. A ball-type valve disposed in the chamber is formed intermediate the ends of a valve stem rotatably mounted in a bore provided therefor in the body. A passageway extends through the ball to provide communication either between the inlet and delivery ports or between the delivery and exhaust ports. A valve cover member carried on the end of a pipe has two concentric skirts the lar...
