Abstract: FLUID PRESSURE AND VELOCITY      SENSING APPARATUS              ABSTRACT            Apparatus for measuring fluid pressure and velocity, and in particular for maintaining an aspirator air velocity constant under varying atmospheric conditions. A precisely controlled air velocity is provided by a reference air source whose frequency is derived from a crystal oscillator.  The total air pressure from the aspirator wind tunnel is compared with the total air pressure from the reference air source using a matched thermistor pair technique to convert the pressure difference into an electrical error signal which is used to control the main air source for the aspirator wind tunnel such that the error signal is maintained at zero, thereby maintaining the air velocity in the aspirator constant.

Abstract: HAY STACKER            Inventor:  Leroy Staffanson ABSTRACT OF THE DISCLOSURE       An agricultural implement, such as a hay rake, may be easily and quickly connected to our disconnected from the tow bar of a tractor.  The apparatus features a large main frame assembly which extends over top of the tractor to a gound-engaging position in front of the tractor.  The hay basket or other implement is connected to an end of an auxiliary lift frame which is pivotally coupled to the main frame by a hydraulic lift cylinder which permits the implement to be raised from its normal, ground-engaging position to a position far above the top of the tractor for unloading or transport.  A second, tilt cylinder controls the level of the implement during lifting and transport, while a third hydraulic cylinder serves to operate a push-off mechanism for unloading the hay rake.  The apparatus also features a quick-connect-disconnect hitch for coupling to the draw bar of the tractor, and an integrally formed stand for supporting the main frame when uncoupled from the tractor.

Abstract: SPECIFICATION       SECURITY DEVICES FOR ROTATABLE MEMBERS AND FLUID  FLOW CONTROL VALVES INCORPORATING SUCH DEVICES   ABSTRACT OF THE DISCLOSURE    A security device for a rotatable member of a machine element, such as the spindle or  nut of a fluid-flow control valve, to prevent the unauthorised operation thereof.  A turning member having a cylindrical surface is fitted to the valve spindle and a shroud is rotatably mounted on the member, the shroud having lugs which engage parts of the valve to prevent rotation of the shroud when the device is fitted to the valve.  Projections upstand from the cylindrical surface and the turning member can be operated only by a key able to fit within the shroud and over the cylindrical surface, with recesses appropriately positioned to accommodate the projections, such that torque can be imparted to the turning member through the interengagement of at least one projection with a wall of the key defining the associated recess.     A locking device including a pin spring-urged out of a bore in the base of the shroud may engage an appropriate recess in the turning member, further to enhance security.  Such a lock may only be released by use of the appropriate key, to press the pin downwardly to move free of the turning member.    The security device m y be modified for use with a rising stem fluid-flow control valve, and furthermore may be arranged to hold the key in the shroud until the valve has been set to one extreme position -either fully open or fully closed.

Abstract: GROUND-RAKING, ROCK-GATHERING ATTACHMENTS FOR TRACTORS                  Abstract of the Disclosure A bucket mounted ground-raking and rock-gathering attachment is picked up off the ground following rock-gathering, by operation of hydraulic cylinders on the tractor provided for lifting and lowering the bucket.  The tractor is then driven to a dumping site whereat the outer end of the attachment is set down onto a pile of debris or other elevated surface to be supported thereby.  Then, hydraulic cylinders on the tractor are operated to rotate the bucket, for dumping the debris, while the attachment is substantially maintained in position.  A passive tension strap, inter-connected between the top of the bucket and the top of the attachment to limit the extent of downward pivotal movement of the attachment relative to the bucket, bends to permit such dumping rotation of the bucket.  In a second embodiment, a second passive tension strap, interconnected between a top portion of the attachment and an upper portion of the bucket support frame, holds the attachment in a substantially level position while the bucket is rotated to dump debris.

Abstract: Abstract The control circuit arrangement comprises a plant, a controller (3) having an I-member (7) and a servo motor (15) whose rate of adjustment is limited and which is associated with a follow-up (22).   The follow-up enables the operative movement of the servo motor (15) to act on a comparator (11) disposed in the control circuit between the output of the controller (3) and the input of the servo motor (15).   The output of the comparator (11) is also connected to attenuating means (34, 36) which are operative in the entry path of the I-member (7).   The attenuating means comprise a functions pickoff(34) and a multiplier element (36).   The functions pickoff(34) delivers an output signal which is lower for a high absolute value of its input signal than for a low absolute value thereof.   The functions pickoff output signal acts by way of a multiplier element (36) on the entry path of the I-member (7).   Control oscillations of the control circuit operation are therefore obviated, more particularly in the case of periodically occurring abrupt variations.

Abstract: ABSTRACT OF THE DISCLOSURE A fluid pressure proportioning valve, particularly of the type which is used in the hydraulic braking systems of auto-motive vehicles, includes a plug member movably carrying a piston member. The piston member defines a through bore communicating pressurized fluid to an outlet on the plug member. The piston member also carries a valve member opening and closing the through bore in response to reciprocation of the piston mem-ber. A lip seal, spring seat, and a coil spring are carried by the piston member. The plug member, piston member, valve member, lip seal, spring seat 100, and coil spring 110, comprise a unitary subassembly which may be assembled with a housing providing a bore for receiving the coil spring and lip seal and providing an inlet communicating pressurized fluid from a master cylinder. The unitary subassem-bly incorporates virtually all component parts, the dimension of which affect the proper operation of the fluid pressure propor-tioning valve. As a result, the dimensional tolerances of the housing may be relaxed without adverse effect upon the proportioning valve.
