Patent CA-2050223-A1 (CA)
Inventor: WALTZ RICHARD W
IPC: H02H6/00
Filed: 1991-08-29
Abstract: A device protects an electric load, such as a motor, from excessive current levels.  The current flows from a source to the load through a switch and a primary winding of a current sensing transformer.  The voltage across a secondary winding of the current sensing transformer is rectified to produce a voltage which is measured to determine the level of current through the load.  The voltage across the secondary winding also powers components of the device.  In a first mode of operation, current from the secondary winding is applied to charge a power supply capacitor.  In a second mode of operation the level of the rectified voltage is sensed to produce a sample of the level of the current flowing through the load.  From this sample the change in temperature of the load since a previous sample is calculated and used to derive the present load temperature.  When the present load temperature exceeds a defined threshold level, the switch is opened to disconnect the load from the electricity source.

Title: Control of sex differentiation in fish
Inventor: ELBRECHT ALEX
IPC: A61K31/445
Filed: 1992-04-16
Abstract: TITLE OF THE INVENTION CONTROL OF SEX DIFFERENTIATION IN FISH            ABSTRACT OF THE INVENTION      Fish or shellfish eggs, fertilized embryos or hatched fry or shellfish are treated with steroid biosynthesis inhibitors or antagonists which prevents the conversion of androgens to estrogens. By blocking the production of estergens the genotypic female is converted into a phenotypic male. The phenotypic conversion of females to males gives the treated fish the advantage of male growth characteristics. Such treatment will also allow the production of monosex populations of fish which can be used to limit reproduction and control overpopulation of specific aquatic environments. Steroid biosynthesis inhibitors and/or antagonists will also induce smoltification in salmon species.

Abstract: 2067824 9105643 PCTABScor01 Confident that, when cracks occur in a piece of timber due to the heat treatment of the timber, an acoustic emission (AE) should occur, an effective AE signal directly involved with the cracks is discriminated and detected, and, in addition to this, the total (integrated) number of events and the rate of occurrences of AE  are monitored while the drying treatment process and the high temperature treatment process are discriminated to thereby put all above evidences together to predict cracks occurring during the processes of the drying treatment and the high temperature treatment, whereby the temperature and humidity are controlled on the basis of the predicted information to thereby control the atmosphere such that the cracks will not occur. Furthermore, in that case, the timber is impregnated with a specific organic solvent medium to conduct the impregnating treatment where the water and the heat react chemically with each other, whereby the interior of the piece of timber is plasticized and the cracks due to the heating treatment are prevented from occurring and the brittleness in the quality of timber due to the high temperature treatment is greatly bettered, thus improving the workability of the timber.

Patent CA-2078173-A1 (CA)
Inventor: MCNAUGHTON JAMES
IPC: F16L37/098
Filed: 1992-09-14
Abstract: A  unique  retainer  is  disclosed  having  a  plurality  of resilient arms securing a tube within a housing bore.  The arms include a radially inner section having a pair of circumferentially extending braces which increase the strength of the arms.  The braces have axial ends which are bent radially outwardly and increase the strength of the arms, and also result in a more consistent, predictable buckling force for the retainer.  Arm bends are formed between the arm radially inner section and a radially outer section.  The axially outer bends of the braces are generally axially aligned with these arm bends, such that the bends provide a planer surface for positioning the retainer within the housing.   Also,  "bumps" are defined at a radially inner face of  the radially inner sections of the arms to create a high force resisting tube insertion.  The bumps are at an angle relative to a central axis that is greater than the angle of the remainder of the radially inner section of  the arms.   Thus,  the retainer arms may extend at a first angle which is relatively small relative to the axis and can provide a great force resisting tube removal, while the bumps are at the greater angle, and can provide a relatively great force resisting tube insertion.

Filed: 1992-10-19
Abstract: ABSTRACT            A triaxial multioscillator for operation in accordance with a mode of operation requiring the imposition of a substantially uniform axial magnetic field on the gain region of each lasing cavity.  An integral frame of glass ceramic material has a rhombic dodecahedral shape and includes three closed lasing cavities, each formed of four straight segments.          The cavities include three mutually parallel segments, one from each cavity, that are regularly spaced on a circle perpendicular to the axis of the frame.  An internal cathode and six anodes are associated with the frame to provide gain in each of such three segments.  The frame is positioned within a closed cylindrical element of soft iron composition by means of a fixture.  The fixture positions magnets adjacent the top and bottom of the element to generate parallel lines of magnetic flux therein.  The frame is positioned within the container in such a way that the cavity segments containing the three gain regions are aligned with the parallel lines of flux to produce the requisite axial fields in the three gain regions.

Filed: 1992-10-20
Abstract: An apparatus and method therefor substantially reducing the interference of a harmonic frequency component (301) of a clock signal with a filtered received signal (302), comprises a frequency spreading signal generator (127) and a signal modulator (125). The frequency spreading signal generator (127) produces a frequency spreading signal (130). The signal modulator (125) modulates the clock signal, produced by a clock signal generator (129), with the frequency spreading signal (130) to produce a modulated clock signal (131) including a modulated harmonic frequency component (303). The power level of a modulated harmonic frequency component (303), corresponding to the harmonic frequency component interfering with the filtered signal (202-204), is spread over a frequency bandwidth (f6-f7) greater than the predetermined frequency bandwidth (f4-f5) causing the power level of the modulated harmonic frequency component (303) within the predetermined frequency bandwidth (f4-f5) to decrease.

Title: Metal carbides and derived composites
Inventor: NINHAM BARRY W
IPC: C04B35/65
Filed: 1991-06-12
Abstract: Metal carbides may be formed by mixing metal powder with a stoichiometric amount of graphite, compressing the same in a mould/die and then sintering. High temperatures (and may be a bonding agent) are required to effect the final step and finished product.  These disadvantages are overcome by exploiting dry high energy milling to bring the starting materials into a very finely divided and reactive state, with regions of metal, carbon and metal based solid solution ranging from 3 to 100 nanometres in diameter. As an alternative source of carbon, cationic organic surfactants may be used instead of graphite in the appropriate proportion.  Compacting the milled mixture, followed by sintering at lower temperatures by a margin of at least 400 ·C, will produce very strong dense carbides at low cost. The method may be extended to include metal based composites, which also includes cermets, by incorporating an appropriate excess of metal powder(s) in the starting materials. The carbides and their metal based composites have applications in the field of abrasives, cutting tips for lathe tools, masonry drills and master alloys for steels.
