Abstract: A cover assembly is provided which is adapted for use on a receptacle transporting vehicle having a receptacle supporting scull frame swingable from a receptacle transport position to a dumping position for discharging molten contents of the receptacle. Included in the assembly is an insulated lid member for opening and closing the receptacle, the closure position retarding heat loss from the molten contents to preclude solidification during transport thereof between spaced locations. A pair of laterally spaced-apart support arms, mounted so as to move concurrently with the swingable scull frame, position the lid member adjacent the top of the receptacle during scull frame movement and especially during transport of the receptacle from one location to another. A pivot assembly rotates the support arms for similar movement of the attached lid between receptacle opening and closure positions, such movement being independent of the scull frame movement.

Also, in the preferred embodiment, the electrodes are connected across the high voltage ignition circuit of a motor, such a motor thereafter consuming the treated fuel, to thereby establish a high intensity electric field within the treater region.

Abstract: A sprayer boom assembly comprises an elongate spray boom having outwardly foldable wing sections with a center portion pivotally mounted to an upstanding support frame of a transport vehicle for vertical swinging movement as the vehicle traverses uneven terrain. A biasing frame is pivotally mounted to the vehicle frame and the spray boom center section and connected to the spray boom through shock absorbers to dampen shocks and oscillatory movement of the spray boom. The biasing frame is tiltable about the pivot so that the spray boom can be selectively tilted to one side or another while retaining shock absorbing capability in any position. The wing sections include outer and inner wing sections of which the outer wing is automatically foldable against the inner wing through a translational to rotational movement arrangement which is actuated upon folding of the inner wing relative to the center section.

Abstract: A control system for an overpressure relief arrangement includes a valve providing selective communication between a pressure passage connected to a pressure vessel and a pair of relief passages, each relief passage having an overpressure relief device therein; sensors for monitoring the pressure in the pressure passage, the status of the relief devices, and the position of the valve; an actuator to move the valve; and a computer to make decisions concerning the placement of the valve based upon the data derived from the sensors. The valve normally provides communication between the pressure passage and first relief passage preferably having a rupture disc therein. Upon rupture of the disc, the system pressure is monitored until it is safe to switch to the second relief passage without overpressuring the relief device therein.

The lactylate salt is thermally mixed with from about 2% to about 30% (by weight) of hydrogenated stearin which has from about 50% to 100% (by weight of fatty acid) C.sub.18 fatty acid and an iodine value of less than 7.

Abstract: A control circuit for an ultrasonic dental scaler, comprising a transducer driven by a frequency-controlled oscillator, is disclosed. The control circuit is operable for continuously regulating the oscillator frequency at substantially the same value as the resonant frequency of the transducer with a dental tool attached to it and for controlling the mechanical power output of the transducer. The transducer can be drivingly connected to a work tool for transmitting mechanical energy thereto. The regulation of the oscillator frequency is accomplished by simultaneously applied control signals derived from the current passing through the transducer and from the voltage across the transducer, to compensate for supply voltage variations. Moreover, the mechanical power output of the transducer is controlled such that it is reduced whenever the contact pressure of the work tool exceeds a predetermined maximum value.

Abstract: A universal auxiliary implement mount for agricultural implements utilizes spaced, parallel, triangular plate members for attachment and selective positioning on respective tool bars of different main implements. A draw tongue is pivotally attached to one pair of a pair of mounting apertures extending through central portions of the triangular plate members. A biasing rod has one end which is pivotally attached to the draw tongue and extends in an upward angle with the other end thereof received in an apex portion of the triangular plate members. The biasing rod has a spring therewith which selectively exerts downward pressure on the draw tongue while allowing vertical movement over rough ground surfaces.

Abstract: A removable gooseneck for detachably connecting a tractor and trailer utilizes an elongate beam member attached to the hitch of the tractor and having an upstanding frame member depending from a rear end of the beam member. A foot is pivotally mounted at a lower end of the upstanding frame member for engagement with a front end portion of the trailer. A guide pin and link arrangement detachably connects the foot at a front end to the trailer and a locking pin and bushing arrangement detachably connects the rear end of the foot to the trailer at a location spaced from the guide pin and link arrangement. A power fluid ram extends between an upper portion of the upstanding frame member and the foot to selectively cause the foot member to swing upwardly and tilt the trailer downwardly for detachment of the gooseneck from the trailer and swing the foot downwardly to tilt the trailer upwardly for drafting.

Abstract: A damper assembly is provided which comprises a duct having an opening and a blade movable between a closed position in covering relation to a portion of the opening and an open position. A fusible retainer holds the blade in its open position and releases the blade when the retainer is sufficiently heated. When released, the blade is urged to its closed position by a hinge member which connects the blade to the duct. The blade in its closed position cooperates with the hinge member to substantially prevent flow of fluid through the opening.
