Patent CA-2191808-A1 (CA)
Inventor: ELSINGER HERBERT
IPC: H01R12/62
Filed: 1996-12-02
Abstract: A casing 14 for a junction included in a flat cable 10, e.g  for a trigger stage of a sequential blasting system, consists of two casing portions 12, 13 adapted to be fixed to each other by screwing within the lead-through regions of the cable. The casing portions 12, 13 constitute cramping areas for fixing the cable 10 to the casing 14 in a direct, non-positive way, wherein the screws 23 which interconnect the two casing portions 12, 13 at the same time create the cramp-ing pressure. An additional positive engagement between the cable 10 and the casing 14 is achieved by engagement between a tube 25 which receives the screw 23 and a hole 29 provided in a centre web 28 of the cable. Tensile strain occurring within the cable 10 is thus diverted via the casing 14 around the electrical equipment provided in the casing and soldered to the wires 19 of the cable 10.  Even under high tensile forces,  the soldering points are thus not exposed to any strain.

Title: Paperboard container for fluids having an improved lower fitment restraint structure
Inventor: BENNER CHRISTOPHER T
IPC: B65D77/06
Filed: 1997-02-07
Abstract: A container for fluid material including an upright tubular shell having a top end and a bottom end. The shell includes upright first sidewalls having a first width and an upright second sidewall having a second width that is less than the first width.  The second sidewall is interdisposed between the pair of first sidewalls. The bottom end of the shell is closed, and a flexible impervious liner with a fitment attached for emptying the liner of fluid materials is located within the shell.  A lower portion of the second (narrow) sidewall defines an outer opening with a vertical dimension greater than a cross-sectional portion of the fitment to be inserted therethrough.  The second (narrow) sidewall has greater resistance than the first (wide) sidewall to transverse motion, which decreases the likelihood of structural failure of the container as a result of transverse motion of fitment and associated sidewall.  Accordingly, locating the outer opening in the second (narrow) sidewall decreases the likelihood that the container will fail.  A bottom cap covers the bottom of the container and includes a tab constructed of solid fiberboard with an inner opening having a horizontal dimension substantially greater than the cross-sectional portion of the fitment.  The vertical dimension of the inner opening is less than the vertical dimension of the outer opening so that as the fitment moves in a vertical direction it will strike the top and bottom periphery of the inner opening, instead of the outer opening, thereby reducing damage to the outer opening.

Inventor: STOLARSKI EBERHARD
IPC: C22B11/00
Filed: 1997-03-07
Abstract: The ore which contains gold and at least one of the metals silver, copper, nickel, zinc or iron is calcined at temperatures in the range from 500 to 900°C with the addition of oxygen-containing gas, thereby producing a metal-oxide-containing solids mixture and a SO2-containing exhaust gas. The SO2-containing exhaust gas is brought in contact with aqueous solution, thereby producing a sulfite-containing solution. The solids mixture from the calcination is cooled to temperatures in the range from 50 to 300°C and is stirred up with the sulfite-containing solution. Metal oxides are dissolved, and a sulfate-containing solution is formed. In a first separating zone, the sulfate-containing solution is separated from the solids, and either the solids are supplied to a gold leaching or the sulfate-containing solution is subjected to a further treatment for the separation of non-ferrous metals.

Abstract: In a safety device for containing broken wheels, it is known that a cable system wrapped around the wheels will stop them from  leaving the undercarriage. These cables will be guided by fixed rigid supports, stationary to the equipment. The cables will have secure eyelets on each measured to a pre-determined length. Turnbuckles will be required to tighten the cables and have adaquate thead length to compensate for cable sag. The application of this WHEELTAINER will vary on equipment, being that all equipment is not a standard size throughout the industry. The cables will have sufficient tire clearance to avoid either cable or tire damage. Cables should be manufactured from a non-corrosive type material such as stainless steel and installed at equal spacing on the side of the wheel (see drawing). The corner supports will be round pipe, half-round guides will be welded to them where the cable turns the corner. The guides will hold the cable in place and prevent it from sliding up and down pipe. The other fixed supports can be square pipe with drilled holes to guide the cables and will be located between the wheels.

Title: Dilution system for filling spray bottles
Inventor: MCCALL JOHN E JR
IPC: B65D1/02
Filed: 1995-12-18
Abstract: The invention relates to an apparatus far diluting liquid concentrate materials to liquid use solutions. An aspirator system (16) is adapted to receive a container (11a) of liquid concentrate in a reservoir (10). The reservoir contains means (13) to open the liquid concentrate.      Additionally the reservoir contains means to support the liquid concentrate during addition of concentrate to the reservoir. When empty, the liquid concentrate bottle can be placed in a reservoir for the empty container (11b).      The receiver has filling means for the container that can deliver dilute use solution to the container. The liquid concentrate container and the dilute use solution container are substantially identical. The apparatus is controlled using a flow controller (14) that activates liquid diluent causing the liquid diluent to pass through the aspirator drawing concentrate at a fixed dilution ratio. The aspirator can be used in a station with multiple apparatus, each adapted to a particular liquid concentrate and dilute use solution. The typical container for such a station comprises a plastic bottle (11) having a fitment adapted to the receiver opening means.      The preferred container for the liquid concentrate contains a fitment comprising a closure for the bottle opening having impressed into the closure a circular indent operatively connected with a thick hinge member. When inserted into the reservoir, the opening means causes the fitment to fail at the circular indent resulting in a clean separation of the circular portion from the closure permitting the contents of the concentrate container to drain into the reservoir.
