Patent CA-2130391-A1 (CA)
Inventor: SIMARD JOSEPH E L
IPC: F42D3/04
Filed: 1994-08-18
Abstract: ABSTRACT OF THE DISCLOSURE    In a method of mining ore by drilling boreholes in a section of  ore-bearing  rock,  detonating  charges  in  the  boreholes, excavating the ore-bearing material, backfilling the section with debris and cement,  and repeating the exercise for the next section, the drilling of more than one blast expansion pocket is avoided by installing a blast expansion tube against the exposed end face of the vein, before backfilling the cavity.  For ease of installation, the column is formed by a plurality of tubular segments. Each tubular segment comprises a flat panel to face the end face of the vein and a curved panel to extend into the cavity.  The segments fit together in spigot and socket fashion to give a relatively rigid tube.  The rigidity may be increased by internal bracing struts.  The tubular segments have pivotal couplings so that each segment after the first can be coupled to its predecessor before being lifted into the vertical position and  slotted  into  it.    Each  segment  has  a  pair  of  cable attachments in the form of shackles or other suitable devices enabling the column of segments to be suspended by cables during installation.  With the column of segments installed, the cavity is backfilled, the charge boreholes drilled, and the next section blasted.  The blast expansion tube is destroyed by the blast and removed with the debris.   Each segment may comprise a closed compartment formed by means of a pair of closure plates secured across end portions of the segment.

Title: Welding process and mixture of reactants for use in such process
Inventor: ASSEL MARK
IPC: B23K23/00
Filed: 1994-12-06
Abstract: The invention provides a new and improved process and exothermic reaction mixture for use in the process for producing molten weld metal. The molten weld metal is used in joining one non-ferrous metal piece with at least one other metal piece. The process and exothermic reaction mixture have distinct advantages over the prior art. These advantages include a higher filler metal yield, reduction of odor, and a higher quality corrosion resistant weld. These advantages are accomplished by a process wherein a reactant mixture is provided which has a reducing agent, a filler metal which does not react with any of the compounds of the mixture, and two or more metallic compounds which are exothermically reduced by the reducing agent. The metallic compounds subsequently form a compound, with the reducing agent, having a high heat of formation which provides an exothermic reaction with sufficient heat to melt the filler metal. The reactant mixture is exothermically reacted to release heat and melt the filler metal and provide a flow of filler metal from the reactant and product mixture which may be contacted with objects to be welded by the filler metal.

Title: Gas Flow Control Assembly for a Gas-Saving Oxy/Fuel Cutting Torch
Inventor: BISSONNETTE CLAUDE
IPC: B23K7/10
Filed: 1995-01-25
Abstract: A novel gas flow control assembly for a gas fuel cutting torch is disclosed. The gas flow control assembly provides a gas-saving oxy/fuel cutting torch which may be operated in a pilot mode when the torch is not in active use.The gas flow control assembly includes an inlet end and an outlet end. The inletend is adapted for the attachment of a fuel gas conduit and an oxygen conduit. The outlet end is adapted for the attachment of a fuel gas tube, a preheat oxygen tube and a cutting oxygen tube which provide fluid communication of fuel gas, preheat oxygen and cutting oxygen from the control body to a torch head. Passages through the control body are normally closed by biased valves having stems which extend through fluid tight seals in a top of the control body. A lever pivotally connected to the control body is arranged to simultaneously depress the stems of the valves which normally close the preheat oxygen and the fuel gas passages when the lever is manually operated to a first position. Further operation of the lever depresses the stem of the valve which normally closes the cutting oxygen passage. A small orifice, preferably bored through each of the valves in the preheat oxygen and the fuel gas passages permits a controlled flow of fuel and oxygen gases through the gas flow control assembly to permit the torch to operate in the pilot mode wherein a small flame is sustained at a nozzle installed in the torch head. The advantage is that a cutting torch is provided which saves significant quantities of fuel gas and oxygen because it may be instantly switched between pilot mode and preheat/cutting mode.

Patent CA-2149896-A1 (CA)
Title: A radar-based method of level measurement
Inventor: BURGER STEFAN
IPC: G01S13/88
Filed: 1994-09-20
Abstract: In a method of level measurement on a radar basis, microwaves are emitted by means of an antenna to the surface of a material in a container and the echo waves reflected from the surface thereof are received. An actual echo function representing the echo amplitudes as a function of the distance is formed from the echo waves received by the antenna for each measurement, the probable useful  echo  and the transit time thereof  are established from the actual echo function, and the distance of the material surface from the antenna is determined therefrom. To recognize the formation of a deposit and/or other trouble, such as e.g. damage to or loss of the antenna, an undisturbed echo function corresponding to an undisturbed measurement is obtained and stored prior to performing the measurements.  In each measurement the actual echo function is compared to the stored undisturbed echo function. When due to the comparison, deviations between the two functions are found in the antenna region and the proximity zone, these deviations are evaluated to recognize the formation of a material deposit and/or other trouble.
Patent CA-2153142-A1 (CA)
Title: Slick line casing and tubing joint locator apparatus and associated methods
Inventor: KILGORE MARION DEWEY
IPC: E21B47/09
Filed: 1995-06-30
Abstract: A detector structure is used to sense and log the joints in a downhole jointed tubular structure, such as a well bore casing or production tubing, in a subterranean well. The detector is moved through the jointed tubular structure on an elongated positioning member, representatively a slick line, through a series of joints to be logged. As the detector passes through each joint it electromagnetically senses the joint and responsively generates an electric output signal. The output signal is used to momentarily cause a drag structure portion of the detector, in cooperation with the interior side surface of the tubular structure, to momentarily create a detectable tension change in the elongated positioning member. Alternatively, a pyrotechnic or compressed gas device may be used to create the detectable changes in response to the generation of the electrical output signals. These tension changes, which may be either tension increases or tension decreases, serve as mechanical output signals transmitted upwardly through the positioning member, and may be plotted on a strip chart recorder at the surface to record the joint locations and correlate them to the lowered depth odometer readings of the detection system. Using this joint detection apparatus, correlative joint logging procedures may be carried out for tool setting purposes without the necessity of utilizing an electrical conductor line.

Abstract: Ce procédé de fabrication de la silice utilise une technique dont les principales opérations sont le lessivage des silicates naturels au moyen d'acide chlorhydrique ou d'autres acides minéraux, l'essorage, le séchage et le cas échéant un broyage des restes du produit ainsi obtenu. Pour obtenir des billes de silice caractérisées par une granulométrie contrôlée et des propriétés de surface, la matière première employée est une olivine minérale du plus haut degré possible de pureté. Cette matière première est broyée en grains d'un calibre compris entre 0,05 mm et 5 mm. Les particules sont prétraitées et lavées pour éliminer sur leur surface la poussière et les produits lourds tels que le spinelle et une partie au moins des minéraux en forme de feuille et de tige tels que la serpentine, le talc et le pyroxène. Les particules d'olivine subissent ensuite un lessivage contrôlé jusqu'à obtenir la granulométrie primaire voulue, des propriétés de surface spécifique et un volume des pores dont on s'assure qu'il est conforme aux spécifications par une mesure selon la méthode BET appliquée à la silice extraite. L'agglomérat ainsi formé est constitué de billes d'un calibre compris entre 30 et 70 nanomètres. Après lavage et séchage traditionnel, les billes constituant l'agglomérat se séparent les unes des autres.
