The sides of the squeeze chute have front and back pairs of bracket plates for receiving the front and back edges of the side panels. As the panels are dropped into place, a cam located between the back pair of bracket plates shifts the panels forwardly to position their forward edges between the front pair of bracket plates.

Abstract: For an automobile with a gasoline fuel system wherein fuel is delivered by a fuel pump from the gas tank to a carburetor and on to the engine through an intake manifold, a substitute non-petroleum fuel system including a storage tank from which liquid fuel is pumped to an atmospherically maintained vaporization tank fitted with a heating coil. Mixed air and fuel vapors, the flow being regulated through a second accelerator, are fed directly from the vaporization tank to the intake manifold of the engine. The vapor tank is also equipped with an electrical resistance heater to facilitate engine starts. An alternative embodiment teaches mechanical linkage and circuitry for selectively operating either the gas or substitute fuel system through a single accelerator pedal.

Abstract: A switch which is actuated when a preselected fluid pressure differential is exceeded. A piston exposed to the pressure differential carries a plunger which contacts a lever arm mounted on a shaft. A spring normally prevents the shaft from turning but is overcome when an excessive pressure differential is applied across the piston. A switch arm mounted on the shaft actuates the switch in response to turning of the shaft.

Abstract: This invention relates in general to a universal frequency synthesizer which is suitable for use in a phase-locked loop frequency synthesizer system comprising a voltage controlled oscillator, a reference oscillator and a low pass filter. The universal frequency synthesizer of the present invention is basically comprised of programmable divider circuitry and a phase detector.The universal frequency synthesizer is arranged to receive tuning data in serial format from an external source. The received tuning data is permanently stored within the universal frequency synthesizer and is used to establish the division ratio by which the output signal produced by the synthesizer's attendant voltage controlled oscillator and the reference signal produced by the synthesizer's attendant reference oscillator are divided before being provided to the signal and comparison inputs of the phase detector, respectively.

Abstract: An agricultural tool bar having a main beam and a pair of tool supporting side wings which fold forwardly from an extended operating position to a folded transport position. The inner ends of the wings are attached to hinges which are pivoted to a carriage mounted for rolling movement along the main beam. Hydraulic cylinders pivot the hinges relative to the carriage as diagonal links cause the carriage to roll along the beam in a manner to fold and unfold the side wings. Additional hydraulic cylinders act to raise the main beam to the transport position wherein the side wings are wholly supported on the main beam which is in turn supported on a wheel assembly having a sturdy axle underlying it.

Abstract: An accessory for facilitating the accurate cutting of holes with a cutting torch. A die is attached to the workpiece by legs and presents a die opening which controls the size and shape of the hole. A bridge piece fits against the die and maintains the cutting torch tip perpendicular to the surface of the workpiece as the torch is guided around the edge of the die opening to form the hole.

Abstract: A rock picker of the floating rotating reel type has the following features: (1) An intermediate pinion is provided for the drive of the reel at the pivot point for the reel assembly. This enables the reel to pivot to clear obstacles without per se changing the relative driving relationships; center-to-center distances can remain constant regardless of the pivoting of the reel. (2) Loosely attached grille teeth permit rocks to wiggle out from between grille teeth. Each grille tooth is provided with a receptacle and shoulder which bears against an angle-iron transversely located on the frame. Clearance between the receptacle and the angle iron permits wiggling of the teeth to occur. A bolt passing through a spacer flange attached to each tooth prevents the tooth from sliding off the angle iron.

Abstract: The present invention encompasses a novel spring construction and a method of application of the spring in the field of orthodontics. A tension spring member is at least partially surrounded by a tension releasable component of larger diameter. The tension spring will normally be a coil spring adapted to be placed under tension between two points. The tension releasable component will normally comprise either a closed coil spring or an open coil spring. In either case, the tension releasable portion comprises an integral extension of the tension spring member and is designed to deform in response to a predetermined force thereby releasing the device from its tension exerting position. The orthodontic method of the invention comprises anchoring one end of the novel tensioning device to a tooth to be moved and the other end to an anchor point. The device is then placed under tension and the tension releasable means is used to hold one end of the device.

Abstract: A feed trough attachment for converting a grain wagon into a portable cattle feeder. The trough is equipped with a pair of mounting arms which are bolted to the frame of the grain wagon to mount the trough below the gravity discharge outlet opening of the grain box.

Abstract: A device which attaches to a motorcycle or bicycle handlebar to hold a beverage can.

The lid can be raised for removal of the can from the body.

Abstract: An adjustment mechanism for adjusting the maximum flow rate of conditioned air in an air distribution system controlled by a pneumatic control circuit. An air bladder controls the distribution of air, and the pressure is bled from the bladder under the control of a diaphragm against which pressure is fed back from the downstream side of the bladder. The control orifice through which the bladder pressure is exhausted is formed in the end of an exhaust tube that is axially adjustable. A cam and set screw arrangement serves to extend and retract the exhaust tube to move the control orifice toward and away from the diaphragm for adjustment of the maximum flow rate.

Abstract: A two point hitch for a mowing implement towed by a two point hitch tractor. The hitch structure includes a pair of upstanding plates which are pivotally pinned to the hitch arms of the tractor. A pair of support arms projecting from the implement underlie the hitch arms. When the hitch arms are raised, the support arms come into contact with them and the implement is thereafter raised in unison with the hitch arms to an elevated transport position.
