Title: Hot asphalt transfer and application device
Inventor: CRISPINO LOUIS T
IPC: E04D15/07
Filed: 1994-04-11
Abstract: ABSTRACT     The present invention provides a machine for automating the transferral and application of hot asphalt material to roof surfaces. The machine includes a number of reels attached to an outer shell contained on a cart. Each reel contains roughly five-hundred feet of hose and attaches to one of two types of hand-held applicator devices. An electric generator, a storage tank assembly, and a pump assembly are contained within the outer shell. The combination of heating elements disposed within the storage tank and heating wires wrapped around the inner tube members of the hoses keeps the asphalt material in a liquified form during operation of the device. Compared to other conventional methods and apparatus, the present device greatly enhances the safety and efficiency associated with hot asphalt roofing.
Patent CA-2123719-A1 (CA)
Title: Bitumen up-grading
Inventor: JONES MANSEL E
IPC: B03B9/02
Filed: 1994-05-17
Abstract: Bitumen (heavy oil) deposits are found in many countries but particularly in Northern Alberta and Saskatchewan.     Many of these deposits contain oil so heavy that only a small fraction  (or none)   of the oil can be recovered by conventional drilling: oil from these deposits are high in carbon and sulfur and low in hydrogen content; the cost to  recover  the  bitumen  product  and  up-grade  it  into marketable liquid fuels for modern transportation has been very high. It is an object of this invention to introduce new up-grading methods  that will simplify up-grading and substantially reduce the costs;  also to introduce methods to treat the coke content so it can become an environmentaly acceptable fuel for the production of energy.     Two  well  developed  methods  are  used  to  up-grade bitumen!   Suncor  uses DELAYED COKING,  while Syncrude has adopted a method known as FLUID COKINGg; these 2 systems are  known  as  carbon  deletion,  removing  coke  from  the volatile  liquid content  of  the bitumen:  the coke  being removed from the bitumen has a high sulphur content (+-8%) making  it  unacceptable  as  a  fuel;  Syncrude  stock piles their coke, choosing rather  to use natural  gas as fuel, Suncor uses some of the coke as fuel for its operations but must lime treat the flue gases to remove SO2 to make the  fuel  environmentaly acceptable,  the remainder of the coke  is  stock  piled.  A May  issue  of  the Times  Herald reported that   Suncor plans  to  spend  $175 mm over the next several years to up-grade their flue  gas treatment facilities,  to make  their flue gases more environmentaly acceptable.

Title: Insulated dryer drum
Inventor: TIMM GERALD L
IPC: F26B13/18
Filed: 1994-08-25
Abstract: The invention pertains to apparatus for thermally insulating selected portions of a cylindrical dryer drum, usually  adjacent  the  drum  ends, for  the  purpose  of obtaining a substantially uniform drum shell temperature throughout its length to obtain a uniform moisture profile throughout the width of the web being dried.  A plurality of cylindrical segments are bolted together within the drum interior  to  define  a  circumferential  assembly biased against the drum inner surface.  The segments each include a thermal insulation material engaging the drum shell preventing direct access of that engaged portion of the shell with the steam within the drum thereby reducing the exterior temperature of the drum shell at the location of the thermally insulated segment.   The segments may be bolted together, widthwise, to increase the axial dimension of the temperature controlling segment assembly.

A backing sheet is formed in such a structure that an elastic nonwoven fabric is laminated with a film having water vapor permeability and water proofing property, whereby sufficient flexibility and excellent water vapor permeability are provided and help to keep skin respiration and not only to prevent skin irritation caused by stickiness with perspiration or the like but also to completely prevent permeation of water, a detergent aqueous solution or the like into a pad portion or an affected part and further to prevent infection of a wound with bacteria. The preventions can be more completed by sealing the edge portion of the adhesive bandage via heat-sealing or the like. Further, the use of the laminating film can realize improvement in break strengths and abrasion resistance of the adhesive bandage, and improve handling characteristics in adhering the adhesive bandage to the affected part.

Abstract: A method for mitigating crack initiation and propagation on the surface of metal components in a watercooled nuclear reactor. An electrically insulating coating is applied on the surfaces of IGSCC-susceptible reactor components. The preferred electrically insulating material is yttria-stabilized zirconia. The presence of an electrically insulating coating on the surface of the metal components shifts the corrosion potential in the negative direction without the addition of hydrogen and in the absence of noble metal catalyst. Corrosion potentials ?-0.5 Vshe can be achieved even at high oxidant concentrations and in the absence of hydrogen.
