Patent CA-2132060-A1 (CA)
Title: Wheel-load sensor with piezoelectronical measuring element
Inventor: GASSNER SIEGFRIED
IPC: G01G19/02
Filed: 1994-09-14
Abstract: A wheel load sensor (10) designed to be installed in a recess in the surface of a roadway and used for the selective detection of the vertical directional component of a pressure emanating from a wheel load; said sensor comprises a piezoelectric measuring element (11), a conductor acting as an inner electrode (12) and a hollow conductor (13') acting as the outer electrode and serving to define a measuring axis, which is necessary for the selective directional detection of the pressure, by clamping wall sections (16) of the piezoelectric measuring element oriented approximately parallel to the plane of the road surface, while the remaining wall sections (16') of the piezoelectric measuring element are arranged in the hollow conductor (13') at a distance from the other walls of this conductor. In the installed position, the measuring axis, which coincides with the clamping axis (P), is oriented perpendicular to the surface of the roadway. Since the wall sections (16') of the piezoelectric measuring element (11) located at a distance from the hollow conductor (13') are oriented approximately transversely to the measuring axis, this design substantially eliminates the transmission of horizontal pressure components from incoming pressure waves to the piezoelement (11).

Title: Method and Apparatus for Acquiring and Identifying Sidewall Core Samples
Inventor: MAISSA JACQUES
IPC: E21B49/06
Filed: 1994-10-26
Abstract: A method and apparatus for acquiring a plurality of sidewall cores from an earth formation intersected by a wellbore while a coring tool is located downhole. A sidewall coring tool is provided having an internal core receptacle for receiving and storing sidewall cores in serial orientation. The coring tool incorporates a movable bit box providing rotary support and linear coring and retracting movement of a rotary coring bit. A bit box tilting and rotation actuator is incorporated within the coring tool for achieving breaking at the core sample from the formation and forselectively positioning of the bit box and rotary coring bit at a coring position where the bit is oriented in normal relation with the axis of the wellbore and a core ejecting position where the rotary coring bit is positioned in registry with the internal core receptacle for deposit of cores in serially oriented relation therein. Another actuator is provided for accomplishing lateral coring and retracting movement of the rotary coring bit for acquiring a core and for retracting the bit and core within the coring tool. A third actuator is provided within the coring tool for displacing cores from the rotary coring bit into the core receptacle after the rotary coring bit has been positioned in registry with the core receptacle. A mechanism is also provided for locking the coring bit against inadvertent extension during bit box rotation. The sidewall coring mechanism further incorporates a reduction gear transmission permitting slow speed, high torque rotation of the coring bit, which transmission is automatically disengaged when the bit box is rotated from the coring position.

Patent CA-2139760-A1 (CA)
Title: Coating process and compositions
Inventor: JONES IAN THOMAS NISBET
IPC: B29C47/86
Filed: 1993-07-06
Abstract: A process for coating a metal substrate for packaging end use comprises applying to a primary substrate a suitable, substantially solvent-free thermosettable composition. The composition is applied as a thermosettable film by extrusion in melt (including plastified) form through an extrusion coating die onto a substrate, and there is relative movement between the die and the substrate so that successive areas on the substrate are coated with the thermosettable composition, so as to form a film. The primary substrate is the metal substrate for packaging end use or an intermediate temporary support from which the applied coating is transferred onto the metal substrate for packaging end use, and the applied coating is thermally cured after extrusion through the extrusion coating die. Compositions suitable for use in this and other coating processes are described.

Filed: 1995-02-16
Abstract: La présente invention se rapporte à une fixation permettant de fixer rapidement deux pièces ensemble sans l'aide d'outil ou avec des outils simples et de les démonter simplement en débloquant la fixation. Elle comprend une tête ayant une prise pour un outil approprié, un corps cylindrique, une extrémité fendue pour former deux pattes pouvant se rapprocher quand on enfonce la fixation dans un trou, avec des épaulements pour l'empêcher de ressortir du trou lors d'une traction longitudinale sur la tête de la fixation.

Abstract: A process of recycling used sulphur-cured elastomeric materials comprising masticating the said elastomeric materials at temperatures below 50°C with a novel chemical mixture which is capable of initiating proton exchange in a controlled manner and thereby open up or delink the vulcanised network of the elastomeric materials. The novel chemical mixture is made from one or more compounds which are capable of performing rubber accelerator function and one or more activators capable of initiating proton exchange at temperatures below 70°C and thereby open up or delink the vulcanised network of the sulphur-cured elastomeric material to provide sulphur-curable reclaimed elastomeric material.            The preferred mixture comprises zinc salt of dimethydithiocarbamate andmercaptobenzothiazole in the molar ratio in the range of 1:1 to 1:12, preferably dispersed in diols, and activated in the presence of stearic acid, zinc oxide and sulphur. This mixture when blended with vulcanised elastomeric crumbs in concentrations of 6 parts binder per 100 parts of rubber crumbs on a mill effectively delinks the vulcanised network and renders the compound ready for moulding and vulcanization. The obtained recycled rubber compounds display satisfactory level of physical and dynamic characteristics. Such compounds can be directly used in moulded goods or in admixture with fresh compounds in tyres and related areas.

Title: Power supply to a stator of a polyphase reluctance machine
Inventor: DAVIS REX MOUNTFORD
IPC: H02P9/40
Filed: 1995-07-10
Abstract: A polyphase switched reluctance machine has only n power cable connections  for n phases.   Each phase winding includes a series connected diode  and the phase windings and their diodes are arranged in a conducting ring. Alternating  currents  are  fed  to  the  nodes  of  the conducting ring from an inverter.  The nodal connections between the phases allows the alternating current to energise the windings where previously only a greater number of cables and a unidirectional current would have been  required.   Due  to  the presence of  alternating current,  a transformer may be interposed between the inverter and the nodes of the conducting ring to allow a boosted voltage to be delivered over long distances.

Abstract: The present invention provides a method and apparatus for automated DNA sequencing. The method of the invention includes the steps of: a) using a processive exonuclease to cleave from a single DNA strand the next available single nucleotide of the strand; b) transporting the single nucleotide away from the DNA strand; c) incorporating the single nucleotide in a fluorescence-enhancing matrix; d) irradiating the single nucleotide to cause it to fluoresce; e) detecting the fluorescence; f) identifying the single nucleotide by its fluorescence; and g) repeating steps a) to f) indefinitely (e.g., until the DNA strand is fully cleaved or until a desired length of the DNA is sequenced). The nucleotides are advantageously detected by irradiating the nucleotides with a laser to stimulate their natural fluorescence.

Title: Method and apparatus for controlling an electro-optical switch
Inventor: PAGE JERRY L
IPC: H04B10/29
Filed: 1994-01-25
Abstract: A control arrangement for minimizing optical leakage in a time-division, multi-stage electro-optical switch by the periodic adjustment of switching voltage levels.  An optical detector connected to an idle port of the switch transmits a leakage signal which represents optical leakage in the switch in various configurations of the switch.  The leakage signal is filtered by a low pass filter and sampled at a low rate. A processor stores the sampled data and periodically analyzes the data to determine the appropriate changes in the switching voltage levels for each of the stages of the switch to minimize optical leakage.  An output circuit connected to the processor and the switch modifies a previously determined base voltage signal for each of the stages to incorporate the voltage level changes and applies the modified signals to the switch in the appropriate time slots.
