Abstract: A valve installation for a flume wherein a preinstalled liner is cast in place at the time of flume construction. The valve body with sealing gasket is later installed within the liner. Wedge plates and associated force-applying bevelled washers are installed around the periphery of the valve body within the cast groove which receives the liner. The bevelled washer can be actuated to force the valve body against a gasket compressing the gasket to form a seal and for locking the valve body in the liner. Removal for servicing is easily accomplished by the removal of the bevelled washers.

Abstract: A positive-acting mechanical device to constantly monitor the amount of thrust force on the bearing housing end plate of a roller support for a rotary kiln.

Abstract: A high density, high lift storage loader having facilities for sideloading, floor loading and front loading a standard beam-type pallet rack and also having a capability of providing means for order picking adjacent the operation. The arrangement provides a straddle-type high-lift apparatus provided with straddles which are located at the height of the first shelve of the storage structure. The load is carried on a chain-type mechanism and is rotatably mounted to the lifting carriage of the machine by a drive ring. The drive ring is movable longitudinally along the carriage support arms and is coordinated with locating and reaching movements. An operator carriage moves with the load carrier so that the operator controls the apparatus at all times with the load in view. Floor loading is accomplished without the necessity of a counterbalance.

Abstract: An air disconnect switch incorporates a unique arrangement of an ice breaking self-polishing current transfer horn arrangement which transfers the current to a puffer-type interrupter to effect circuit interruption prior to the disconnect switch being fully opened; the puffer-type interrupter is a dielectric insulated device which has its operating mechanism disposed within the dielectric insulating medium so that the system has no fast-moving external parts and provides a direct drive with minimum maintenance of the mechanism parts. The porcelain tube serves both as the interrupter housing and as the mechanism housing.

Abstract: Sulfur oxides have a strong affinity for free lime and readily form gypsum anhydrite. By utilizing 2200.degree. F or higher on-gas containing reduced quantities of sulfur to the preheat zone of a material treating apparatus, large quantities of sulfur can be removed from gases evolved in the rotary kiln. Utilizing lower sulfur content on-gas to preheat will substantially improve the ability of the system to lower both sulfur and alkali levels in the clinker. Substantially free lime in the form of fines is introduced into the kiln off-gas stream to form gypsum anhydrite which is removed and has the potential to be utilized as a by-product. Essentially all of the remaining gaseous sulfur that has not been absorbed by the lime bearing dust is absorbed by the free lime in the pellets in the preheat zone of a material treating apparatus.

Abstract: A strategically located series of spaced apart classifiers set at varying depths within a pelletizer pan operated to classify the forming pellets and also impart controlled energy into the forming pellets producing pellets of improved quality. Controlled classifying of the forming pellets stabilizes pellet output. With a stabilized pellet output obtained the need for driving the pellet pan with a variable speed device can be eliminated since pan rotation can be maintained at a constant speed.

Abstract: A service stand integral with the rotary kiln carrying mechanism to facilitate field maintenance of the kiln roller supports and eliminate the danger inherent in field constructed blocking.

Abstract: A radially extending scoop is fastened internally to the discharge end wall of a ball mill structure for rotation with the mill; rotation of the mill will cause the grinding media and pulp to cascade and the scoop will fill and direct the material inwardly toward the mill center and discharge it into a conical cylinder in the mill trunnion which directs the discharge into a receptacle.

Abstract: A feeder distributor is mounted above an annular crushing chamber of a gyratory crusher and operates to distribute feed uniformly around the entire circumference rather than at one revolving point. A rotating cylinder has a rotating bottom plate of larger diameter connected to it by ribs leaving a circumferential opening between the cylinder and the plate. The circumferential opening is sized to prevent the flow of material when the cylinder and plate are not rotating. When rotating, the material is thrown off of the plate around the entire circumference of the plate by centrifugal force. This provides good continuous distribution of material around the entire crusher chamber regardless of the feed rate into the cylinder.

Abstract: Apparatus for removing solids such as iron oxide pellets and fines from the rotating water seal trough of an annular material cooler by periodically operating an air ejector pump, which is suspended in the trough and operated at predetermined intervals and for a predetermined time; the ejector pump has associated with it a sensing apparatus both being pivotally mounted and suspended within the trough; an abnormal build-up of pellets and fines in the trough or large foreign bodies within the trough is sensed by the sensing means which actuates emergency means to override the normal pump operating cycle and maintain the pump operating and simultaneously alerting personnel to the emergency condition.

Abstract: A support for a rear mounted flexible grass catcher container is mounted directly to the mower body and is free to pivot back for clearing the container from the mower shroud, when necessary for service purposes, without disconnecting the support from the mower. The support pivot is disposed in a manner that the applied load from the grass catcher container causes a resulting moment which tends to hold the container rear support in operative position without the necessity of providing clamps or catches. In addition, the rear support serves as a barrier for the container preventing its engagement with the adjacent rear wheels of the mower.

Abstract: Electrical potentials are induced in the rotating shaft of many rotary electrical machines because of stray flux that exists in the machines. Unless provided with adequate ground insulation to interrupt the circuit, currents can flow through the machine bearings and other parts to ground and thereby expose the machine to severe damage. The device of this invention provides a sandwich-like ground insulation with a conductor therebetween and measures the voltage across that portion of the insulation between the conductor and either the bearing housing or ground to indicate if there is a circuit for excessive current leakage from the bearing to ground.

Abstract: A gas insulated circuit breaker arrangement incorporating a modular interrupter structure and having a centrally disposed single opening pull-rod and stopping means for both ends of the pull-rod stroke for controlling the movement of all of the masses of the moving parts. The acceleration spring always opposes the closing force thereby insuring that the pull-rod is in tension. Compression structure is provided to resist the tension force applied by the pull-rod and also to stabilize the interrupter structure.

Abstract: The gas-on pipe is supported independently of the firing hood to provide for a greater length of the gas-on pipe thereby reducing the deflection stress in the gas-on pipe to acceptable values; adjustments to the end of the gas-on pipe is facilitated during kiln operation to obtain low stress values; the location of the end of the gas-on pipe is not affected by thermal expansion of the firing hood; and cooling process air leakage into the firing hood which causes overheating or process complications is eliminated.

Abstract: A high voltage center break disconnect switch assembly having an integrally cast aluminum base usable as cast with provisions for shaft and gear adjustments without disassembling the switch and utilizing open stainless steel bearings.

Abstract: Centerline of the pinion and gear is offset from the centerline of the bore in which the pinion bearing housing is contained. A change holds the bearing housing in operating position and is also operable to rotatably adjust the pinion housing, the O.D. of which is eccentric relative to its I.D. Thus rotation of the bearing housing within the bore effects the adjustment of the vertical height of the pinion relative to the driving gear.

Abstract: A shell gas burner is provided to preheat a kiln wherein the burner can be also used for process axial air and has provisions for retracting the burner for protection from high heat source or extending the burner for ease of replacement.

Abstract: A high voltage gas insulated circuit breaker in which a resistance shunts the main interrupter contacts to control the magnitude of the surge voltage experienced when the interrupter is closing. The resistance includes a resistor switch comprising a plurality of stacks of resistor segments connected in parallel. The smaller surface area of the segments tends to resist cracking due to mechanical thermal stresses and provides a higher resistivity thereby being capable of withstanding more voltage. The parallel stacks of resistor segments provides for a more compact resistor switch without sacrificing the basic operational requirement.
