Title: Process for preparing composites based on oriented mesogenic thermoset resins
Inventor: JONES ROBERT E JR
IPC: C08J5/24
Filed: 1993-07-15
Abstract: Continuous fiber reinforced oriented mesogen-containing resin matrix composites are prepared by (A) saturating a continuous fiber substrate material with a curable composition comprising (1) at least one mesogen-containing resin which contains an average of more than one vicinal epoxide group, thiirane group, cyanate group or vinyl ester group per molecule; and, optionally, (2) a curing amount of at least one curing agent and/or curing catalyst therefor, (B) arranging one or more saturated continuous fiber substrate material(s) formed in step (A) into a desired configuration; (C) subjecting the arranged saturated continuous fiber substrate material(s) from step (B) to a temperature which causes the mesogen-containing resin to convert to a liquid crystalline state; (D) subjecting the heated arranged saturated continuous fiber substrate material(s) from step (C) to a pressure sufficient to cause flow induced shear in the interstices of said continuous fiber substrate; (E) subjecting the continuous fiber substrate material of step (D) to curing conditions either simultaneously with the application of pressure in step (D) and/or subsequent to said application of pressure; and (F) permitting the cured continuous fiber reinforced composite of step (E) to cool to room temperature; thereby forming a cured continuous fiber reinforced composite containing an oriented mesogen-containing resin matrix. These composites have improved properties as compared to composites which are not oriented.

Title: Fluid activated detonating system
Inventor: YUNAN MALAK E
IPC: F42D1/04
Filed: 1993-10-07

Patent CA-2181094-A1 (CA)
Inventor: DAHLER PETER
IPC: H02M7/155
Filed: 1996-07-12
Abstract: A common  turn-off  circuit  for  a  thyristor power  converter  is  specified.    The  common  turn-off circuit is particularly suitable for AC converters such as, for example, railway grid couplings.  The turn-off thyristors  are directly connected   to the  secondary transformer  windings.    Additionally  provided  is  a special freewheeling path via which the energy stored, in particular,  in the transformer inductors or other relevant  inductors  can  be  drawn  away.    What  is advantageous is the fact that all of the thyristors of the  power converter can be turned off  reliably and without any special precautions, since the common turn-off circuit is  automatically ready for turning off. Overvoltages  are  avoided,  moreover,  by  the  special freewheeling path.

Title: Method of treating waste water to remove harmful ion by coagulating sedimentation
Inventor: IKEDA KENICHI
IPC: C02F1/58
Filed: 1996-07-30
Abstract: The invention relates to the treatment of waste water containing a harmful ion such as a heavy metal ion or fluorine ion by the coagulating sedimentation method using an inorganic coagulant such as an iron compound or an aluminum compound. After separating treated water from the sediment (sludge) in which the harmful ion is incorporated in insoluble form, the pH of a mixture of the sediment and water is suitably adjusted to cause elution of the harmful ion from the sediment. Then the sediment is separated from the eluate and reused as an inorganic coagulant. By reusing the sediment in this manner, the waste water treatment is accomplished without producing a large quantity of sludge and the consumption of inorganic coagulant and auxiliary chemicals can be greatly reduced, while the concentration of the harmful ion in the treated water becomes sufficiently low.

Patent CA-2184765-A1 (CA)
Inventor: DOMANIK RICHARD A
IPC: G05B19/10
Filed: 1996-09-04
Abstract: A machine, method and medium for implementing functions using an input device in a manner that enhances efficient operation of a mechanism capable of operating in at least two states. The functions are implemented via a convenient input device, such as a mouse. One or more specified actuators of the input device implement a given function when the mechanism is in a first state, while at least one of those actuators implements a different function when the mechanism is in a second state. In embodiments of the present invention contemplating that the mechanism is a microscope system, two states in which the microscope system is envisioned to operate are a scan state and a pause state. The scan state allows the microscope system to execute a predefined scan sequence, while the pause state allows the microscope system to pause from that sequence.

Title: Method of preserving plywood and particle board against decay and mould
Inventor: LEHTONEN MARKKU
IPC: B27K3/34
Filed: 1996-12-17
Abstract: The present invention is related to a method of preserving plywood, particle board and similar wood composite products made from wood pieces/particles and a binder used to adhere such wood pieces/particle together against rot and mould decay.  According to the invention, the preservative of the wood material is a complexing agent which is capable of binding transition group metals and is admixed into the binder used in the manufacture of said wood composite products prior to the formation of said product.  The invention also concerns a binder composition, which contains a polymer resin as its adhesive component and a complexing agent, particularly an aminotetracarboxylic acid or a salt thereof, by approx. 1-30 wt.-% as the preservative of the wood material, and a method of producing said binder composition.  Tests performed on faced plywood indicated that a water-soluble, environmentally safe complexing agent offers a white rot resistance which is superior to conventional preservatives commonly used today.

Title: Method of increasing coagulation efficiency during electrocoagulation printing
Inventor: CASTEGNIER ADRIEN
IPC: B41C1/10
Filed: 1996-12-30
Abstract: An improved electrocoagulation printing method comprising the steps of (a) providing a positive electrolytically inert electrode capable of releasing trivalent metal ions and having a continuous passivated surface moving at substantially constant speed along a predetermined path, the passivated surface defining a positive electrode active surface; (b) forming on the positive electrode active surface a plurality of dots of colored, coagulated colloid representative of a desired image, by electrocoagulation of an electrolytically coagulable colloid present in an electrocoagulation printing ink comprising a liquid colloidal dispersion containing the electrolytically coagulable colloid, a dispersing medium, a soluble electrolyte and a coloring agent; and (c) bringing a substrate into contact with the dots of colored, coagulated colloid to cause transfer of the colored, coagulated colloid from the positive electrode active surface onto the substrate and thereby imprint the substrate with the image. The improvement resides in maintaining the positive electrode active surface and the ink at a temperature of about 35°C to about 60°C to increase the conductivity of the ink and the release of trivalent metal ions from the passivated surface into the ink in step (b) so that the trivalent metal ions initiate coagulation of the electrolytically coagulable colloid and are released in a quantity sufficient to increase the optical density of the coagulated colloid, thereby increasing coagulation efficiency in step (b).
