Title: Hydrostatic propulsion system and method with inching throttle and brake
Inventor: KASSAI DENES P
IPC: F16H61/46
Filed: 1984-05-14
Granted: 1987-02-10
Abstract: ABSTRACT OF THE DISCLOSURE  A hydrostatic propulsion system and method of operation is disclosed for smoothly driving a vehicle, such as a street sweeper.  The system includes a shift lever for selectively moving a pump stroking valve into reverse, neutral, low forward, and fast forward speed positions to prepare the system.  After the shift lever has been placed in a forward or reverse position, an accelerator pedal must be depressed to partially or fully close an inching throttle valve before the pump swash plate moves from its zero piston displacement position and begins to pump fluid to the hydrostatic motors.  Hydrostatic braking forces are applied when the accelerator pedal is released and also in response to initial depression of a brake pedal for providing normal braking to the vehicle.  Further depression of the brake pedal operates a conventional brake system for panic stops.  Movement into the high forward speed range is accomplished by moving the shift lever into "high" which activates a circuit for shifting the swash plates of the hydrostatic motors into high speed positions.

Abstract: ABSTRACT OF THE DISCLOSURE:           A container for storing radioactive materials which includes a closing cover tightly secured to the outer layer of the container vessel by a continuous weld seam. The container includes an annular body which is attached to the outer layer of the vessel.  The annular body has an inwardly directed flange overlapping the weld seam for protecting the latter against external blows which could occur, for example, during transport of the container.  The container also includes two narrow slots formed in the annular body with U-shaped guides disposed therebeneath for receiving transport elements in engagement therewith.  The annular ring therefore also serves as a transport ring for facilitating transport of the container.   Since the container is held at the ring,  tension forces are directed to the outer layer of the vessel and away from the weld seam.

Abstract: Abstract An actuating mechanism is provided for a circuit breaker.  The actuating mechanism includes a frame and a pair of contacts supported relative to the frame. One of the contacts is supported on a contact carrying arm which is displaceable about a contact arm pivot to open and close the contacts.  A cradle arm is rotatably connected to the frame and has latched and unlatched positions.  A releasable latch holds the cradle arm in its latched position against the bias of an over-center spring.  The over-center spring is connected between the contact arm and the cradle arm to bias the contact arm into over-center positions about the contact arm pivot.  An actuating link is pivotably mounted on the frame and is coupled with the contact arm so that when the cradle arm is held in the latched position, movement of the link from a first position to a second position displaces the contact arm pivot over center relative to the connections of the over-center spring on the cradle arm and the contact arm, causing the over center spring to move the contact arm to close the contacts.  An electrically actuated trip mechanism releases the latch under predetermined conditions to permit displacement of the cradle arm under the bias of the over-center spring from the latched position to an unlatched position.  Such movement moves the connection on the cradle arm over center relative to the contact arm pivot, thereby causing the over-center  spring to move the contact arm to open the contacts.  A cradle arm return spring displaces the cradle arm from the unlatched position back to the latched position and causes the link to rotate from the second position back to the first position as the over-center spring continues to bias the contact arm to hold the contacts open.

Abstract: FIBER OPTIC PHASE MODULATOR              Abstract of the Disclosure A fiber optic phase modulator produces a pure phase modulation in a signal propagating along a standard low birefringence optical fiber without producing an accompanying change in the polarization of the signal. A pair of fiber squeezers under the control of an oscillator apply two in-phase perpendicular forces to the fiber.          Changes in length and changes in the refractive indices of the compressed fiber in each squeezer cause a phase difference and a polarization change between the input and output signals. The changes in the phase of the signal caused by the stresses resulting from the perpendicular compressions are cumulative while the polarization changes are equal and opposite. The phase modulator includes a transducer capable of applying forces to the fiber at high frequencies such that the phase modulator is suitable for use in fiber optic systems such as  optical gyroscopes and other interferometric sensors.
