Abstract: ABSTRACT OF THE DISCLOSURE    A tower crane is carried on a platform rotatably mounted on a large ring with the tower pivotally mounted on the forward portion of the platform above the ring and a mast mounted on the platform adjacent the boom and extending upwardly and rearwardly therefrom.  A counterweight support at the rear end of the platform also rides on the ring and is connected to the top of the mast by a backstay.  At the top of the tower is a pivotally mounted, forwardly projecting boom and an upwardly and rearwardly inclined boom strut whose upper end is pin-connected to the top of the mast by a backstay strut.  A tower backstay is connected to an upper part of the tower and extends generally horizontally rearwardly to the top of the mast where it is also pin-connected.          By removing the pin-connections at the top of the mast, the tower, boom, boom strut, backstay strut and tower backstay can be pivotally raised and lowered as a unit by powered erection rigging mounted on the platform.  A pendant is connected between an intermediate point on the tower backstay and a lower point on the tower to insure that the openings for the pin-connections at the top of the mast are properly aligned when the tower is erected.  Additional hoist mechanisms and rigging are carried on the platform for adjusting the boom angle and for raising and lowering a load.  In the preferred embodiment, the crane includes two laterally spaced towers, booms, masts, backstays and struts interconnected as described above.

Abstract: PROCESS FOR REGENERATING SULFUR DIOXIDE GAS SCRUBBING SOLUTIONS           Abstract of the Disclosure It is known to remove sulfur dioxide from gas streams, particularly waste or flue gases, by contact with aqueous scrubbing solutions con-taining a metal salt, such as ferric sulfate, in which the valence of the metal is reduced by the sulfur dioxide.  It is also known that such scrubbing solutions can be regenerated by oxi-dizing the reduced metal salt, such as ferrous sulfate, back to the higher valence for further use in removing sulfur dioxide.  According to the invention, the regeneration of the scrub-bing solution is advantageously effected by electrolytic or anodic oxidation, rather than air oxidation, of the reduced metal salt, since anodic oxidation is not adversely affected by the increase in sulfuric acid content of the scrubbing solution which results from the con-version of the sulfur dioxide absorbed in the scrubbing solution.

Abstract: ABSTRACT Disclosed is a mechanical/electrical control device for displacing an item to a desired position, the device including at least one proportional transmitter which is able to be deflected by hand out of a rest position and which produces a deflection signal corresponding to the deflection.  Each transmitter is associated with a position signal transmitter connected to be controlled by the deflection signal of the proportional transmitter for producing a position signal for displacing the item.  Between each proportional transmitter and the associated position signal transmitter there is an associated arresting device for arresting the deflection signal due to a deflection of the proportional transmitter which occurs in response to the point of reversal before the proportional transmitter is restored to its rest position.  The device is useful for displacing a marker on the screen of a picture tube.

Abstract: ABSTRACT There is provided an apparatus and method for selectively coiling a transfer bar or allowing the bar to pass uncoiled through the apparatus.  A frame supports a number of rollers which can transfer a bar in one direction, and conventional bend roller means are located above the rollers, adapted to apply a down curvature to a transfer bar.  Pivotal ramp means upstream of the bend roller means can either direct a transfer bar through the bend roller means, or allow the transfer bar to pass along the rollers under the bend roller means. A displaceable roller downstream of the bend roller means and parallel with the rest of the rollers is provided, and is mounted for displacement normal to its axis in a direction having a vertical component, whereby the roller may be moved between a first position in which it lies even with the rest of the rollers, and a second position in which it is raised above the level of the rest of the rollers.  The displaceable roller defines an angle with two rollers sequentially downstream from it, the vertex of the angle being at the adjacent downstream roller, whereby the angle changes from 180° to an obtuse angle as the displaceable roller moves from its first to its second position.  The displaceable roller in the second position defines, with the two sequentially downstream rollers, a cradle in which the convolutions of a coiling transfer bar can be contained.  This cradle is capable of enlargement to accommodate the expanding coil, by lowering the displaceable roller toward its first position.

Abstract: Fiber Optic Strain Sensor Abstract An optical fiber having at least two cores posi-tioned in a common cladding can be fabricated to be responsive to strain or hydrostatic pressure but not to temperature through the selection of materials, spacing and shape of the cores and cladding in the fiber.  Accordingly, the cross-talk between adjacent cores in the optical waveguide can be optimized to respond to a change in hydrostatic pressure or in unidirectional strain along the length of the fiber. The strain or pressure change, can be determined by measuring the relative intensity of light emerging from the different cores of the fiber.  A larger unambiguous range for strain or hydrostatic pressure changes can be provided by a multi-core optical fiber embodiment.
