Title: Delayed, exothermic, alkaline sterilization method for treating wastewater sludges
Inventor: WURTZ WILLIAM O
IPC: C02F11/13
Filed: 1992-12-08
Abstract: A method and product for sterilizing and drying waste products such as plant sludge, animal excrement and process wastes wherein the waste material is first settled or dewatered to a moisture content between 4% to 60% and then blended in blender (1) and reacted in reaction chamber (3) with alkaline earth metal oxides in the presence of an atmosphere of carbon dioxide, and in the absence of the oxygen. After the sludge is blended with the alkaline earth oxides, the carbon dioxide is removed so that air or oxygen will contact the blended constituents. A violent exothermic reaction takes place between the water in the constituents and the alkaline earth oxides, causing a rapid rise in temperature of the constituents and thus sterilizing the constituents to produce a safe and usable end product.

Title: Face plate
Inventor: STEWART IAN
IPC: E21D11/00
Filed: 1993-01-04
Abstract: ABSTRACT     A generally square face plate (1) for use with a 16 mm threaded rockbolt (2) includes a centrally located generally hemispherical raised portion (3), a top surface (4) and a curved engagement surface (5) for abutting an excavated surface into which a rockbolt is to be installed.  An aperture (6) is centrally disposed in portion (3) for receiving the threaded end of rockbolt (2) for allowing tensioning of the rockbolt.     A circumferential corrugation (10) is adjacent to and surrounds portion (3).  Four radially corrugations (11,12,13,14) extend from portions (3), through corrugation (10), two respective corners (15,16,17,18) of plate (1).  The corrugations co-operate to allow plate (1) to be effective when used on uneven surfaces, as the plate will progressively deform to accommodate the surface contour and increase the area of contact between plate (1) and the excavated surface.  During any subsequent movement of rock restrained by rockbolt (2), face plate (1) will continue to compensate for changes in rockbolt tension.

Title: Fiber optic sensor system for strain and temperature measurement
Inventor: LU ZHUO J
IPC: G01D5/26
Filed: 1993-09-07
Abstract: Abstract of the Disclosure Three  types  of  temperature  compensated fiber  optic  external  cavity  strain  sensors  and methods of operation thereof are disclosed as well as an intensity-based fiber optic external  cavity sensor and system.  The fiber optic external cavity sensors each comprise  an input optical fiber and a wire bonded together in spaced axial alignment by a connecting  sleeve wherein  respective  ends  of  the fiber and the wire face one another and are spaced apart a predetermined distance to define an air gap. The  ends  of  the  input  fiber  and  wire  form  two reflective surfaces.   The temperature compensation methods involve either keeping the air gap unchanged with respect to temperature variations or having a temperature sensitive reflector at the tip of the wire.   An  intensity-based  external  cavity  sensor comprises  an input  fiber which  is  a  single mode fiber.  An optical bandpass filter is deposited at the end of the single mode fiber.   A reflector is also provided at  the  end of  the  wire.    In  the intensity-based sensor system, an LED, two couplers, and a pair of photodetectors are used.   There is also a bandpass filter, which is similar to the one in the sensor, in front of the photodetectors.  The spectrum of the  return  light  from the  sensor  is modified  as  the  air  gap  changes.    The  spectral changes   are   detected   by a   simple   spectral ratiometric method, which ratio the signals of the two detectors.

Abstract: A PROCESS FOR THE PREPARATION OF TRANS,TRANS-4,4'-DIAMINO-DICYCLOHEXYLMETHANE            ABSTRACT OF THE DISCLOSURE     The present invention relates to a new and easier process for the preparation of 4,4'-diaminodicyclohexylmethane having a high content of the trans,trans-isomer. This process comprises 1) condensing an isomeric mixture of 4,4'-diamino-dicyclohexylmethane with carbonyl compounds in the presence of a non-polar organic solvent which forms an azeotrope with water, which is heated to remove the reaction water and form the corresponding diimine, 2) isomerizing the solution of diimine by adding at least one base, and at least one polyether and/or c) a crown ether, to the diimine solution and allowing these to act on the diimine for at least 3 hours at room temperature or at an elevated temperature, 3) separating the trans,trans-4,4'-diaminodicyclohexylmethane diimine which crystallizes out of the solution, and 4) hydrolyzing it in a known manner to yield trans,trans-4,4'-diaminodicyclohexylmethane. It is also possible to add seed crystals of the corresponding trans,trans-4,4'-diaminodicyclohexylmethane diimine to the isomerized solution of diimine, or simultaneously while separating the diimine which crystallizes out of the solution.      Other variations of the process are also disclosed.
Patent CA-2121878-A1 (CA)
Inventor: HAIGHT EHRICK K
IPC: B01J8/08
Filed: 1994-04-21
Abstract: A system for heat exchange processing of particulate solid material is disclosed.  The particulate solids are flowed by gravity through a housing packed with flat, internally cooled (or heated) heat exchange panels spaced apart to define generally vertical channels for the passage of the solid particulate.  The panels are formed of opposed metal  sheets,  sealed  around  their  edges,  spot  welded together in limited areas of joinder, in a predetermined pattern over their surfaces, and hydrostatically expanded in the areas between to form surfaces that are quilt-like in appearance.  The panels are configured in two alternate forms such that, when a plurality of panels are assembled in a stack, the hydrostatically expanded portions of one panel are disposed opposite the areas of joinder of an adjacent panel  of  alternate  configuration,  creating  a sinuous, but relatively uniform flow path for the flow of particulate solids between panels.  High system efficiency is achieved by enabling adjacent panels to be spaced closer together while still avoiding the problem of "bridging" of the solid particulate material between panels.
