Title: Parallel microprocessor architecture
Inventor: SAVARIA YVON
IPC: G06F15/80
Filed: 1990-02-07
Abstract: ABSTRACT         A multicomputer chip has a common bus and up to ten microcomputers connected in parallel to the common bus via routers contained in the microcomputers.  The common bus can be connected to an external bus by means of a router mounted on or off the chip.  Any defective computer found during testing can be rendered inactive by assigning it an unused address and, in this way, the remaining computers are unaffected.  Instead of providing each multicomputer on a separate chip, a complete wafer may be manufactured so that it contains many of the multicomputers.  A hierarchical bus system interconnects the multicomputers so as to permit efficient routing of data between the various computers.

Abstract: ABSTRACT     "Method of Repairing or Modifying Turbine Blades"        A method of repairing or modifying a turbine blade wherein damage or erosion has occurred to the end part of a turbine blade or it is required to remove the end part so as to improve the efficiency of the blade as a whole comprises the steps of removing the damaged end part or a part  requiring  replacement,  securing  a  new  piece  of material to the blade which may or may not be partly preformed, and after securing of the new piece of material to the blade and heat treatment processes, subsequently working the new piece of material so that it conforms to the desired shape.   The working of the new piece of material only after securement and heat treatment ensures that discontinuities such as lacing wire holes, shroud band apertures, tenons etc., are not left with concentrations of inbuilt stress due to the welding or heat treatment operations and if required the new part may be oversize material which ensures that if slight misalignment occurs between the blade and the new piece of material there is sufficient material to enable the part to be worked to the correct shape.

Patent CA-2016624-A1 (CA)
Title: Load bearing concrete panel construction
Inventor: ALLEN JOHN H
IPC: E04C2/06
Filed: 1990-05-11
Abstract: ABSTRACT As presently designed, reinforced load bearing concrete panels 12, which are intended to be supported between at least two separated supports 14, are over-designed by the inclusion of more flexural reinforcing material then is required to provide adequate structural strength.  It has been determined that panel 12 deterioration and top surface 16 cracking are increased by flexural reinforcing materials 34 and 38 which are located within the top half of the concrete panel 12 in accordance with current practice.  This is due to the fact that flexural reinforcing materials which are in the top half of the panel are subject to corrosion, thereby accelerating degradation, of the panel and increasing the severity of cracks in the top surface.  Therefore, it is now taught that flexural reinforcing material in the top half of existing panels can be entirely removed, and that flexural reinforcing material 20 may be confined to the lower half of the panel, without reducing the strength of the panel below what is required to provide adequate structural strength, and that such panels will in fact exhibit improved durability and reduced top surface cracking.  Various practices to control development of cracking at the top surface due to temperature change and concrete shrinking are employed at the upper half of the panel, other than the use of standard flexural reinforcing material.  The removal of flexural reinforcing material from the top half of the panel results in fewer production steps and in reductions in the cost of construction materials.

Title: Method and apparatus for beneficiating waste-waters
Inventor: TORREGROSSA LOUIS O
IPC: C02F1/78
Filed: 1991-05-15
Abstract: ABSTRACT      Organic constituents in a liquid, such as a waste water from a municipal or industrial process (e.g. bleach plant extraction liquor from the bleaching of paper pulp) may proceed effectively without the addition of alkali.  When the organic constituents are reacted with an oxygen containing gas at appropriate pressure and temperature conditions, oxidized organics and gaseous acidic products of oxidation (e.g. CO2) that are produced are continuously and immediately removed from the liquid so that they do not significantly contribute to lowering of the pH of the liquid, so that the reaction may proceed and the liquid remain alkaline. This may be accomplished in a gas sparged hydrocyclone in which the liquid is introduced into the first end of a vortex while oxygen is introduced from exteriorly of the vortex into contact with the liquid, or may be accomplished by causing the liquid to flow in a thin film in a downwardly extending spiral path and removing the acidic gases from a center portion of the spiral path.  A reactor for effecting the last mentioned specific procedure includes a pressurized vertical vessel having a downwardly extending stationary spiral surface mounted in the vessel substantially concentric With it. Surface manifestations may be provided on the spiral surface for enhancing mixing of liquid with surrounding gas.

Title: Electromedical apparatus for generating low-frequency magnetic field
Inventor: KRAUS WERNER
IPC: A61N2/02
Filed: 1991-05-24
Abstract: ABSTRACT            An electromedical apparatus for generating low-frequency magnetic fields for magnetic field therapy or treatments by the Kraus & Lechner method includes a means (10, 12) for generating low-frequency electrical oscillations of adjustable frequency and amplitude, and at least one applicator coil (32) for generating a low-frequency magnetic field corresponding to the electrical oscillations.  Switching on of the apparatus and initiation of a treatment cycle is by actuating a single key switch (56, 58).  The apparatus is normally switched off after expiry of a treatment period by a time switching device (80) but it can also be switched off by a fault detection circuit (88) which automatically switches the apparatus off on occurrence of disturbances.  With this step operating errors and damage to the apparatus by disturbances are avoided even when the apparatus is used by laymen at home without supervision.
