Title: Slewing bridge material handling apparatus capable of continuous material feeding during moving and slewing
Inventor: SOROS PAUL
IPC: B65G63/00
Filed: 1992-07-07
Abstract: ABSTRACT This  invention  relates  to  a  material handling apparatus,  commonly known as a slewing bridge shiploader or linear shiploader, having front and  rear  pivotal  supports  and  a  movable  boom traversing the bridge.  The front end support of the bridge  is  movable  along  a front  linear  track extending parallel to the ship and the rear support is movable along a rear linear track extending in a direction perpendicular to the front linear track. The bridge contains a conveyor running along its length and also running on the boom, which conveyor is  fed  from the rear end of the bridge.  The conveyor slopes upward from its feed point at the rear of the bridge to the height of the boom, thereby permitting a reduction in bridge span.  As the front end of the bridge moves along the front track,    ?e  rear  end  and  its  support  move longitu   ?lly   along  the   rear  track,   while simultaneously the rear end of the bridge pivots relative to the rear support.   The conveyor feed point is oriented over the rear end pivot point.  A movable trestle carrying a second conveyor is linked to the  rear end of the bridge  for concomitant movement therewith.   The terminating end of the second conveyor is oriented above the feed point of the bridge-mounted conveyor.  As the rear end of the bridge pivots and moves longitudinally, the trestle moves with it, thereby  ensuring continuous feeding of the bridge-mounted conveyor during movement of the bridge.

Abstract: REFRIGERATED DOUGH PACKAGE AND METHOD                 Abstract of the Invention The present invention is directed to a method for making a packaged dough suitable for extended refrigerated storage and to a packaging system for storage of the refrigerated dough. In the packaging system for storage of refrigerated, leavened dough, a substantially rigid tray for receiving a leavened dough product is provided.  The tray has a bottom wall and upstanding peripheral side walls to define at least one well.  At least one leavened dough product is disposed within the well.  The leavening of the dough is at least partially reacted to provide carbon dioxide distributed throughout the dough product.  A hermetically sealed cover, extending at least over the top of the side walls to define a chamber containing the dough product and a headspace surrounding the dough product is provided.  A gas comprising a predetermined amount of carbon dioxide is disposed in the headspace of the chamber in order to create an equilibrium level of carbon dioxide with the carbon dioxide produced in the dough product.  The ambient air is replaced by the gas thereby minimizing the amount of residual oxygen and hence, oxidation of the dough product.

Abstract: A device for controll-ing beams of particles, X-rays  and gamma  rays in-chiding a plurality of chan-nels with total external ref-lection inner surfaces, input butt-ends facing a radiation source and output butt-ends aimed at a radiation receiv-er is taught. Channel-farm-ing elements are in the form of surfaces, tubes, and struc-tures with multiple channels one are rigidly positioned one relative to mother with a spacing between suports such that the sagging of the channel-foaming  elements does  not interfere with beam propagation The de-vice can be used to capture radiation from sources which produce parallel or divergent radiation. The resulting beam or beams can be of a variety of shapes or angular orientations including quasi-parallel, convergent, and split beams.  Energy filtering is accomplished by selective absor-tion of radiation by the channel-forming elements and by selective reflection, by geometrics which cause some energies to be dis-criminated against because of the angle of total external reflection associated with that energy. Also provided are embodiments which use these devices for improved medical imaging, medical therapy, X-ray lithography, and analytic instruments.

Abstract: ABSTRACT OF THE DISCLOSURE      An apparatus for separating material of differing specific gravities while allowing for the collection of graded waste material which includes at least one elongate trough of decreasing volume disposed in a spiral configuration such that the exterior of the trough bottom  forms the interior surface walls of a tubular body.  The trough has a first end, a second end and sidewalls which converge inwardly from the first end toward the second end.  A drive motor is provided for rotating the tubular body such that material is moved along the bottom portion of the trough from the first end toward the second end.  One of the sidewalls diminishes in height from the first end toward the second end, forming a spillway located relative to the lowest point of rotation of the tubular body.  Separation occurs through differing specific gravities with heavier product bearing material remaining in the trough while waste material and waste water is deposited over the spillway in a continuous separation process.  Material is loaded onto the trough by means of a feed channel that is located in the first part of the trough and is part of the trough.  The material may be sorted for size by a series of screens.  Water may be supplied to assist in separation.  Waste is removed from the tubular body and the trough by means of drains.  Product bearing material is collected from the second end of the elongate trough for removal.

Title: Well completions with expandable casing portions
Inventor: SURJAATMADJA JIM B
IPC: E21B17/08
Filed: 1994-04-07
Abstract: Abstract Of The Disclosure Expandable casing portions are provided, such as casing slip joints or expansion joints,  on opposite sides of a fracture  initiation  location  to  accommodate  casing  and formation movement during fracturing of a well.  The fracture initiation  location may be provided by  forming  openings through the well casing and then forming fan-shaped slots in the formation surrounding the casing.   These slots may be formed by a hydraulic jet which is directed through the opening and then pivoted generally about the point of the opening.  These fan-shaped slots circumscribe an angle about the axis of the casing substantially greater than the angle circumscribed by the opening itself through which the slot was formed.   These techniques are particularly applicable to fracturing  of  horizontal  wells,  but  are  also useful  on vertical wells.

Abstract: An improved method for mounting an annular tread 1 onto a tire casing 2 is described. The improved method comprises the steps of expanding the tread 1 radially and encircling the expanded tread with a transfer mechanism 30. The transfer mechanism 30 has a means 90 for holding the lateral edges 5 of the tread 1 in the expanded condition independent of the center 6 of the tread 1. The means 90 for holding the lateral edges 5 of the tread 1 is accomplished without contacting the radially inner surface 7 of the tread 1. The transfer mechanism 30 has a means 92 for circumferentially clamping the central portion of the tread 1 to the casing 2. The transfer mechanism 30 with expanded tread 1 is centered over the casing 2.      The means 92 for clamping the central portion 6 of the tread 1 is actuated while holding the lateral edges 5 of the tread 1 in the transfer mechanism 30. Then the lateral edges 5 of the tread 1 are released from the transfer mechanism 30 thereby transferring the tread 1 to the casing 2 while preventing entrapment of air between the casing 2 and the tread 1.
