Abstract: Abstract of the Disclosure The weld-cladding apparatus includes a turntable which is rotatably mounted in a yoke about a horixontal axis.          An outrigger is mounted on the yoke and has a curvature co-incident to the curvature of the torus-to-be-cladded and a center of curvature on the axis of the turntable.  The weld-cladding means is rotatably mounted at the end of the out-rigger in a vertical plane common to the plane in which the pivot axis of the turntable moves during rotation of the yoke.          During use, the weld-cladding means remains vertical while the turntable pivots on the horizontal axis.  In order to form a weld, the turntable is oscillated back and forth about the pivot axis over an arcuate length equal to the length of the torus.  The turntable is tilted incrementally a dis-tance equal to the width of a weld.

Abstract: Method and Apparatus for Lens Turning ABSTRACT OF THE DISCLOSURE       Apparatus for and method Or forming a surface on, for instance, a contact lens.  The apparatus includes first and second movable members.  The first member is pivotally connected to suitable support structure for rotation about a first axis.  The second member, which supports a cutting tool, is pivotally connected to the first member for rotation about a second axis.  This second axis is offset from the first axis so that it (the second axis) rotates or pivots about the first axis when the first member is rotated.  The apparatus also includes a cam surface and a cam follower.  In the first embodiment the cam follower is located on the second member and the cam surface is located on a cam or third member which is pivotally connected to the support struc-ture for rotation about a third axis.  This third member is also interconnected with the first member so that rotation of the third member rotates or pivots the rirst member about the first axis.  In an alternate embodiment, the cam follower is secured to the support structure and the cam surface ls provided on the sesond member.  In operation, the second member is rotated about the second axis until relative movement of the first member about the cam surface induces movement of the first member about the first axis to therby continuously shift the position of the second axis.  With the first member in motion, a suitable cutting tool secured to the second member under-does a dual movement (rotation about the second axis plus simultaneous movement with the second axis as it pivots relative to the first axis) to form an aspheric surface on the contact lens.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus and a method is described for smoothing the acceleration and deceleration of an electric motor.  This is accomplished by using a pair of brush springs (strong and weak) for each brush of an electric motor.  At low speeds, the strong spring is retracted so that the force with which the brush is applied to the motor commutator is greatly reduced.           This reduced frictional force improves the smoothness of the acceleration and deceleration characteristics of the motor at low speeds.

Abstract: PILOT VALVE               Abstract of the Disclosure A monitor-actuator pilot valve operable with a safety valve in a fluid flow system such as oil and gas wells responsive to either a low fluid flow pressure or electrical failure for closing the safety valve.  The safety valve is held open by a control fluid pressure supplied into an actuator cylinder from the line pressure protected by the safety valve.  The pilot valve includes a body having a first flow passage communicating with the line pressure, a second flow passage communicating with the safety valve actuator cylinder, a third exhaust flow passage open to the atmosphere, and a fourth flow passage connectable with fluid pressure reset means.  A valve assembly positioned in the pilot valve body operates in response to a low pressure in the first passage or electrical failure to connect the second and third passages for exhausting the fluid pressure from the safety valve cylinder to close the safety valve.          An electromagnet is secured with the valve body and mechanically coupled by a trigger assembly with the pilot valve assembly for opening the pilot valve assembly in response to a power failure to exhaust the safety valve actuator cylinder allowing the safety valve to close.  A reset member in the valve body is operable with the valve assembly for restoring the pilot valve to operation either manually or hydraulically.  A hydraulic piston connected with the reset member responds to hydraulic pressure in the fourth passage for resetting the pilot valve.  A manually operable override sleeve is connected   with the hydraulic reset piston and the electro-magnet coupling for manually resetting the pilot valve and the electromagnet coupling assembly.  The pilot valve is thus operable to close the safety valve in response to either a low pressure or an electrical failure.  The low pressure response mechanism is reset hydraulically or manually.   The electrical response mechanism is reset only manually.

Abstract: VAPORIZATION COOLED ELECTRICAL INDUCTIVE APPARATUS   ABSTRACT OF THE DISCLOSURE         Electrical inductive apparatus cooled by a two-phase dielectric fluid which vaporizes within the normal operating temperature range of the apparatus.  The electri-cal inductive apparatus consists of a sealed enclosure sur-rounding a magnetic core and electrical winding assembly.        A non-condensable gas fills a major portion of the enclosure at no-load conditions to provide adequate dielectric strength around the apparatus and is substantially removed to a storage tank when the apparatus reaches normal operating conditions.  The required volume of the storage reservoir is proportional to the free volume of the enclosure and the volume of liquid dielectric disposed therein.  The bottom surface of the enclosure includes a recessed channel portion configured to closely surround the lower yoke of the mag-netic core and which serves to reduce the amount of liquid dielectric utilized and the free volume of the enclosure thereby minimizing the required volume of the storage re-servoir for the non-condensable gas.

Abstract: Abstract A digital transmission system for television video signals is described.  The transmitter is of the type which has several input terminals for receiving respective television video signals to be transmitted, several encoding units for encoding the respective video signals into digitized video signals, and multiplexers for multiplexing the respective digitized video signals in a time division manner.  The receiver is of the type which has a demultiplexer for receiving the multiplexed video signal from the multiplexer and for separating the multiplexed video signal into the digitized video signals, and several decoding units for decod-ing the digitized video signals into the respective television video signals.  The improvement of the invention involves the use of a sync pulse separator for separating sync pulses in the video signal, an encoder responsive to the separated pulses for encoding the video signal into predetermined codes and a generator for generating video-frame-sync codes each indicative of the end of one picture frame.  The two coded signals are multiplexed and stored temporarily in a buffer memory.  The buffer occupancy rate is measured and a corresponding code generated.  The time interval during which the video-frame-sync code is in the buffer is measured.          A second buffer is provided and in the same way as before, the time interval for the second buffer is measured and compared with that for the first buffer.  A read-out address signal is controlled according to the result of the comparison.
