Abstract: ABSTRACT A heat exchanger (10) comprises a matrix made up of alternate  layers  of  generally  planar  sheets  (16)  and generally corrugated sheets (17) which cooperate to define a plurality of parallel passages  (19,20)  for first and second heat exchange fluids.  Alternate of the passages (2) defined by each of the corrugated sheets (17) and its adjacent planar sheets (16) are adapted for the passage of a first heat exchange fluid and the remainder (19) adapted for the passage of a second heat exchange fluid.  The only bonding together of the planar sheets (16) and corrugated sheets (17) is along those portions of their peripheries which are parallel with the defined passages (19,20).

Granted: 1993-09-07
Abstract: Abstract A method for handling, treating, heating and incinerating, on-site, liquid waste, sewage, sludge, cakes or solid waste.  The primary treatment process utilizes a 0.1-50% powder of plastic clay and may include separation, absorption, precipitation, neutralization, sedimentation, flocculation, coagulation, filtration or dewatering.  The residue remaining after the primary treatment is mixed with additional clay or silicates and a suitable absorbent for either organic or inorganic, liquid material, to form a solid mixture of approximately 5-50% clay or silicates and 0.1-10% absorbent.  The solidified mixture is formed into granules or other shapes having large surface area.  The stable, solid granules are transferred to a conveyorized oven, dried and pyrolized or fired.  Resulting organic gases may be condensed to oil or exhaust gases may be vented into a secondary incineration unit.  The resulting product is composed of stable granules, detoxified of organic waste and with all inorganic waste converted into silicate form.

Abstract: ABSTRACT OF THE DISCLOSURE      An expanding nipple, externally mounted packer has a body which mounts onto a stack of blowout preventers or a casing head and tubing spool or the like.  The body contains an external locking mechanism and the upper ends of a pair of concentric mandrels which are lowered into the well casing, through the blowout preventer stack or other configuration of well head equipment.  The outer mandrel has a deformable seal on its lower end and the inner mandrel has an expander on its lower end.  Piston means on the inner mandrel responsive to hydraulic pressure, raises the inner mandrel with respect to the outer mandrel so that the expander forces the seal outwards against the casing wall.  The locking mechanism allows the seal to be locked in place.  The hydraulic pressure on the piston is reversed to unseal the nipple.

Abstract: ABSTRACT OF THE DISCLOSURE         A light source module 100 for use with a multi-camera array 130 in a video surface inspection system includes a first light emitter 104 which extends lengthwise across the entire width of a sheet 106 to be inspected.  Light from the first light emitter 104, which preferably comprises one or more fluorescent lamps, is received by a light guide 110 and carried by the guide to uniformly illuminate a band extending entirely across the width of the moving sheet.  The light guide comprises a transparent thermoplastic such that the light receiving end 118 of the guide can be bent to define a plurality of sections which can be axially aligned with a corresponding plurality of fluorescent lamps.  The light source module can also assist the inspection system in overcoming redundant data processing problems by providing second light emitters 134 which illuminate the sheet in overlapping portions 132 of the fields of view of adjacent cameras of the multi-camera array 130 to define data dividing points.  Accordingly, duplicated data generated by the video cameras can be divided among the cameras at the defined data dividing points such that duplicated data is only processed once by the video surface inspection system.

Title: Methods of and systems for optical fiber sensing
Inventor: DUNN LAWRENCE R
IPC: H04B10/12
Filed: 1989-08-24
Granted: 1993-04-13
Abstract: Abstract An optical fiber sensing system for detecting intrusion of optical fiber or optical fiber cables includes an interferometric arrangement. Two ports of a four port splitter are connected to a source of optical power such as a laser, for example, and to a detector. The other two ports are connected to ends of a length of monitoring optical fiber. An input signal to the splitter is split with one subsignal being directed in one direction around the length of optical fiber which serves as a common path between the two ports. The other signal is caused to travel around the common path in an opposite direction. The split signals are recombined in the splitter and their phase difference measured as a detectable pattern by the detector. Should there be intrusion of the optical fiber or a cable containing the monitoring optical fiber, the pattern which is detected will change a significant amount.

Abstract: ABSTRACT OF THE DISCLOSURE    Hazardous waste is formed into non-hazardous non-leaching aggregate by introducing the material to a rotary kiln where the large solids are at least partially combusted to form a primary aggregate.  Gaseous combustion by-products and waste fines from the waste materials are introduced into at least one oxidizer operating at a temperature in the range of from about 1800°F to 2500°F.  Under such conditions, some of the waste fines are melted to form a slag-like material that is cooled to form the non-hazardous aggregate.  The portion of the material in the ox-idizer that is not melted, is cooled, neutralized and subjected to a solid gas separation.  The solid is reintroduced to the ox-idizer with the primary aggregate where they are either melted or entrained within the molten material and become an integral part of the non-hazardous aggregate.
