Abstract: TWO STAGE HYDRAULIC GOVERNOR     ABSTRACT OF THE DISCLOSURE         A pair of piston valve members are slidably mounted in a housing rotatably engaging the output shaft of the automatic transmission.  A first piston valve moves freely under the influence of centrifugal force within the housing to throttle line pressure from a pump in the transmission to a governed pressure level used for performing shifting functions within the transmission and the second piston valve member is spring biased against the influence of centrifugal force to prevent its movement under the influence thereof until a predetermined output shaft speed is reached whereupon it throttles the line pressure supplied by the transmission pump and directs it to a portion of the first piston valve to vary the operation thereof upon further increases in output shaft speed.  The piston valves are arranged so that no mechanical connection between them is required to effect the two-stage operation and venting of fluid from each of the valves is effected in an outward direction to permit discharge of the contaminants under the influence of centrifugal force.

Abstract: ABSTRACT OF THE DISCLOSURE                      A flow distributor for a fluid bed reactor includes means for decreasing velocity of incoming streams in a uniform, non-turbulent fashion.  Inlet ports communicate with fluid portals having divergent walls to slow incoming flow.  The fluid portals feed liquid flow to a plurality of diffusing flow paths provided between diffusion baffles positioned at the bottom of the reactor.  The diffusion baffles may be priamatic shapes which are trapezoidal in cross-section with the broadest horizontal dimension at the bottom thereof.               The diffusion flow paths therefore have divergent walls and act to further slow the liquid flow passing there-through.

Dividers (24) are spaced along the feed direction and are mounted, pre-ferably on the compartment floor (28), for movement between first positions extending across the feed direction and second positions extending along the feed direction.  In the first positions, the dividers allow storage of the ammunition belt in a serpentine config-uration.  Movement of the dividers to the second posi-tions allows the ammunition belt to pass thereby upon movement to the gun.  Each divider is mounted by a pivotal support (26) having a detent which initially locates the divider in the first position thereof during loading of the belt and which allows subsequent movement to the second position thereof after closing of a compartment closure.  The preferred construction of the dividers includes a shaft (40) with a blade (38) secured thereto and the preferred construction of the pivotal supports includes a pair of bearings that receive shaft ends which extend from the divider blade.

The rays pass over the playing surfaces of the court at a height lower than the height of a tennis ball and when a plurality of rays are employed they are spaced so that a ball in play striking the ground in a monitored area will interrupt the passage of at least one of the rays, thereby actuating a signal.   If the rays are monitoring an area just outside a critical line, i.e. an area in which a ball striking in it would be a 'faint', the signal can be an alarm and an additional independant master ray may be provided to monitor the area just inside the critical line and which, if it is interrupted by the passage of a ball, negatives any subsequent signal.
