Abstract: "STEERING CLUTCH ASSEMBLY AND DISASSEMBLY"     ABSTRACT OF THE DISCLOSURE           A steering clutch and brake power drive assembly wherein a clutch pack and a brake pack formed of a plurality of facially engageable plates are respectively retained be-tween a retaining plate and a housing portion of the assembly by a plurality of bolts which, in the assembled arrangement, provide a preselected stress in biasing springs acting on the clutch plates and brake plates, respectively.  A novel arrange-ment of bolts is provided wherein different size bolts are utilized for facilitating the assembly and disassembly.  A small number of the bolts is made to be sufficiently large so that the assembly may be maintained by a single one thereof notwithstand-ing a high biasing force generated by the spring in the assem-bled arrangement.  An improved lubrication oil transfer struc-ture is further provided to the plate stack from a pressurized oil supply defined by a lubricating oil cavity adjacent the plate stack.  Relatively movable wall portions defining the cavity are effectively sealed to cause substantially all of the oil delivery to the plate stack to be through the transfer pas-sages.

Abstract: ABSTRACT    Aqueous alkaline desulfurization treating units for combustion gases generate as a product an aqueous sludge containing sulfur compounds of calcium.  Many such sludge products contain more than 30 percent by weight (of the solids) of calcium sulfite hemihydrate.  These waste products are in part calcined at a temperature from 250°C to 650°C to produce a moisture-free, cementitious product which is thereafter recombined with uncalcined aqueous sludge to produce a cementitious product which can be profitably utilized or which may be conveniently discarded as a land fill.  If desired, fly ash or bottom ash produced in the combustion process can be combined with the cementitious product.

Abstract: ABSTRACT OF THE DISCLOSURE               For feeding logs to a sawing machine, two parallel horizontal I-beams, at a level above the sawing machine, guidingly support an inner and an outer feed carriage.  From each carriage pincers-like log supporting jaws extend obliquely downwardly and in the feed direction.          The I-beams provide an inner track that has its rails between the rails of an outer track.  The inner carriage is wholly between the rails of the inner track and rides thereon.  The outer carriage bridges over both tracks and rides on the outer one, and its jaw operating mechanism has portions above the level of the inner track and other portions extending down from said level that are laterally outside the outer track.  The carriages can therefore pass one another and exchange leading/trailing relationship for each successive log.  Mechanism is disclosed for causing carriage jaws to close on a positioned log without shifting it but by which the closed jaws can be laterally shifted as desired.

Abstract: ABSTRACT      An apparatus for cutting vegetation wherein at least one line member protrudes exteriorly of the sidewall of a housing which is rotatable about a rotating axis.  The line member is a tape and is wound upon a spool, which is mounted within the housing so that the width, which is greater than the thickness, is perpendicular to the plane of the spool.  The flat tape line member is formed of a flexible band of material which extends exteriorly of the housing in a trailing position.  Cutting means are incorporated to effect cut off of the line member during rotation of the housing and dis-pensing means are provided to extend additional line member a controlled increment of length during rotation of the housing.  The cutting means is provided to cut off the excess end of the worn or broken line member.  A clamping device clamps the line member to the housing when it is not rotating to prevent retraction of the line member into the housing.

Abstract: Abstract of the Disclosure An automatic attitude control system is disclosed for a harvester having a crop pickup connected for pivoting about a transverse axis near the forward end of a crop-gathering head.  The system automatically raises or lowers the crop-gathering head to maintain the angle between the upper run of the pickup belt or conveyor and the head within preselected angular limits to assure proper feeding of the crop from the pickup to a transverse auger or the like on the head.  Two sensors are provided, each with a plurality of reed switches, including a group of parallel "raise" switches and a group of parallel "lower" switches, and a magnetic actuator mounted for relative movement with respect to the switches as the pickup pivots with respect to the head.  The sensor switches are connected to a circuit for activating a control valve for the head cylinders to raise the head when one or more of the switches in either of the "raise" groups are closed by the actuator.  The control valve is actuated to lower the head when at least one of the switches in each of the "lower" groups is closed.  A magnetic shorting bar is positioned between the "raise" and "lower" groups to prevent actuation of any of the switches by the magnetic actuator when the angle between the head and the pickup is within the preselected limits.

Abstract: BRAKE ADJUSTER HAVING MULTI-SIDED INTERNAL BROACH       ABSTRACT OF THE DISCLOSURE A brake adjuster for implementation between the brake housing and pressure plate of a brake disk stack.  A casing is fixedly secured to the brake housing and receives therein a spring follower.  Maintained within the spring follower and engaged at one end thereof is a tubular member. Passing through the tubular member and through the casing is a shaft, the shaft being fixedly secured to the pressure plate at a first end thereof and maintaining a multi-sided broach on the other end thereof.  The broach is of such geometry as to make contacting engagement with the interior surface of the tube.  Upon successive brake applications, the broaching or cutting surfaces of the broach cut portions of the inner wall of the tube, allowing the shaft to telescope from the casing in order to maintain a fixed built-in clearance among the disks of the brake disk stack.  There is no frictional engagement between the broach and the inner walls of the tube and, consequently, no difference in the static and dynamic load characteristics of the adjuster.

Abstract: ABSTRACT OF THE DISCLOSURE         A power shear has a pair of parallel frame plates spaced apart to either side of a fixed blade and a movable blade.  The movable blade can be displaced past the fixed blade to shear a workpiece extending across the plane and resting on the fixed blade.

These edges of the holddown plate are formed with notches that can be aligned with the teeth to allow removal of the holddown plate in a direction perpendicular to its plane.  A positioning spindle threaded through a nut fixed on the one frame plate can have an enlarged head engaged in a T-shaped cutout of the holddown plate so that when the holddown plate is lifted perpendicularly off the frame it is also disengaged from the positioning spindle.

Abstract: (Case No. 7011) ABSTRACT OF THE DISCLOSURE    A varistor disc is press-fitted into recesses formed in opposite surfaces of two metal electrodes, its length selected so that a predetermined air gap remains between the electrode surfaces in parallel to the varistor path.  The assembly is held by a vivet inserted through the three elements with a spring cup washer under the peened rivet end to absorb dynamic discharge forces.  The rivet is insulated by a nylon tube integral with a dust and moisture cover, held at one end by the rivet head and open at its other end for release of gas and particles upon discharge.  The varistor dissipates static voltage buildup and low voltage surges.  High voltage causes arcing between varistor and electrodes within the air gap, which creates a surge discharge across the air gap between electrodes to dissipate surge energy and protect the varistor element.
