Abstract: ABSTRACT:         A camera tube target which to be scanned on one side by an electron beam comprises a selenium-con-taining vitreous layer also containing tellurium and arsenic.  In order to improve the sensitivity and reduce dark current various target characteristics in accord-ance with the invention, the concentration of at least one of the elements tellurium and arsenic in a first layer portion of the selenium-containing layer on the side to be scanned increases in the direction of thick-ness towards the side to be scanned to a value at which the sum of the concentrations of tellurium and arsenic on the side to be scanned is at most 30 at.%; the arsenic concentration everywhere in the selenium-con-taining layer exceeds 1.5 at.%; and in a second layer portion adjoining the first layer portion the concen-tration of at least one of the elements arsenic and tellurium has a minimum value with respect to an adjoin-ing third layer portion.  A fourth layer portion may also be present between the third layer portion and the signal electrode, and the concentration of arsenic and/ or tellurium in the third layer portion may have a max-imum value with respect to the fourth layer portion.

Abstract: ABSTRACT OF THE DISCLOSURE         An automatic table height control for a combine harvester including a height sensing assembly and a control system.  The height sensing assembly includes a finger support shaft rotatably journaled on the bottom of the table.  A spring is provided to rotate the shaft in one direction.  A plurality of ground engaging fingers are pivotally connected to the finger support shaft.  A lost motion connection is provided to limit rotation of the finger support shaft relative to each finger.  An iron vane is attached to one end of the finger support shaft.  A pair of proximity switches are mounted on the crop harvesting table adjacent the path of movement of the iron vane.  When the vane is close to both proximity switches, they are open.       When one of the ground engaging fingers rotates the iron vane away from one proximity switch that switch closes and energizes a relay in the control system that energizes a solenoid on the header height control valve to raise or lower the table.  The position of the proximity switches on the table is adjustable to set the height at which the system holds the table above the ground.  The control system includes a switch and timer which automatically raise the table for a given period of time when the ground drive is reversed.  The control system also includes a latching relay that deenergizes the automatic control when the combine is reversed and energizes the automatic control when the manual height switch is moved to the position for lowering the table.

Abstract: A system for the rapid dewatering of sludge in large quantities makes use of a filter plate of design and construction capable of supporting heavy mechanized mobile equipment without damage to the filter media. The filter plate features a monolithic plate of granular filter material used as the filtering medium in sludge beds for dewatering or reducing residual solids or sludge of potable water treatment systems. The filter material is made structurally rugged and with a smooth hard surface for the retention of sludge solids. The filter material is supported upon a substructure of aggregate providing approximately 40% internal voids for the gravity flow or drainage of filtrate and the back flow of chemicals and gases used in the rapid water reduction process. The assemblage is constructed of such strength as to allow for use of heavy handling equipment such as front end loaders in the removal of the dried sludge or cake upon the completion of the rapid water reduction process. The process follows a cyclical pattern or adjacent sludge beds where raw sewage is pretreated with a polymer coagulant to break up solids and/or to flocculate the sludge particles and then spread on the filter bed as the filter bed is being filled. Large coagulated sludge particles gain weight as they settle, and water is drawn off by gravity while a bed is being filled to the desired designed level. Smaller sludge particles pass to the voids below by a vacumm of 10 to 15 inches when the vacuum is applied, to start the rapid dewatering process through the larger flocculated sludge particles. The mass may be periodically moved and heated while dewatering progresses. Upon completion of dewatering, one or more units of front and loading equipment is used to move the dried sludge cake into heaps and load it into trucks for transport to disposal sites.

Abstract: ABSTRACT         The invention relates to a tube clamp, such as a weasand clamp, wherein there are means for locking the clamp in its closed position. The clamp comprises a quasi-tubular member having in its side wall a slot extending from one end of the clamp to the other, so that the clamp may be fitted to a flexible tube at a position between its opposite ends. Within the tubular member is a hinged flap adapted to press upon the flexible tube, and close it, when there is pressure to move the clamp rearwardly, the hinged flap being arranged to permit the clamp to be moved forwardly.  Moulded integrally with the clamp is a flexible strap having at about its free end a stud or bead which is engageable in a recess or opening provided in the outer wall of the clamp so as to thereby hold the clamp from inadvertent removal from the tube once it has been fitted in position.

Abstract: ABSTRACT OF THE DISCLOSURE            A clamp for handling slabs formed of an assembly of loose concrete blocks has jaws engaging opposite sides of the slab, one of the jaws forming the shorter arm of a lever providing substantial mechanical advantage, the longer arm being moved to a position in which it locks the jaw by almost straightening a toggle linkage.  A lifting force may be applied to the clamp through the toggle linkage so as to generate clamping forces, and a latch may be provided to prevent the linkage from straightening, thus allowing the clamp to be lifted from a slab without clamping the slab.  The clamp enables the slab to be clamped sufficiently powerfully to lock the blocks together.

Abstract: 49,235 ABSTRACT OF THE DISCLOSURE An elevator system including an elevator  car, and control apparatus for controlling its speed, including a speed pattern generator.  The  speed pattern generator provides a running speed pattern,  and a slowdown speed pattern,  wherein the deceleration rate  of  the  slowdown speed pattern may be different than the acceleration and deceleration rates of the running speed pattern.  Bumpless transfer from the running speed pattern to the slowdown speed pattern is achieved by forcing the slowdown speed pattern to match the magnitude of the running speed pat-tern just prior to transfer,  and by initiating transfer when the  rate  of  change  of  the  running  speed pattern equals the rate of change to be followed by the slowdown speed pattern after it is no longer forced to match the magnitude of the running speed pattern.
