Patent CA-2053058-A1 (CA)
Inventor: BRUENING RON
IPC: G01N30/14
Filed: 1991-10-09
Abstract: A method for the removal and concentration of desired ions from a source solution which may contain larger concentrations of other ions including H+ comprises bringing the source solution into contact with a compound comprising a polytetraalkylammonium and/or polytrialkylamine containing ligand covalently bonded through an organic spacer silicon grouping to a solid inorganic support. The polytetraalkylammonium and/or polytrialkylamine portion(s) of the compound has an affinity far the desired ions to forma complex thereby removing the desired ions from the source solution. The desired ions are removed from the compound by contacting the compound with a much smaller volume of a receiving Solution having a greater affinity for the desired ions than does the polytetraalkylammonium and/or polytri-alkyiamine ligand portion of the compound. The concentrated ions thus removed may be recovered by known methods. The process is useful in removing desired or unwanted ions from water streams and in the treatment of waste streams. The invention is also drawn to the polytetraalkylammonium and polytrialkylamine containing ligands covalently bonded through a spacer grouping to a hydrophilic inorganic solid support material.

Title: Hydrocyclone
Inventor: VIKIOE PENTTI
IPC: D21D5/24
Filed: 1991-10-17
Abstract: A hydrocyclone is provided with a wear monitoring element of the type of a tube (24) or the like embedded in the wall section of the shell of the hydrocyclone.  When the furrows worn by abrasive fraction of the cyclone are deep enough to reach the monitoring element, the wear causes a visually observed leak or some other signal alerting the operating personnel to the need of replacing the partly worn hydrocyclone.

Title: Elastomeric triblock copolymer compositions and articles made therewith
Inventor: BUDDENHAGEN DOUGLAS A
IPC: C08L53/02
Filed: 1991-11-21
Abstract: An elastomeric composition is formed of at least two, and preferably three, S-EB-S elastomeric triblock copolymers having different solution viscosity/copolymer concentration relationships, and a sufficient amount of a mineral oil plasticizer to achieve excellent tactility with acceptable strength. To prepare articles such as medical film protective devices, the elastomeric composition is dissolved in a sufficient amount of a solvent to permit dip forming. A form having the shape of the desired product is dipped into the solution to build up a film of the elastomeric composition on the form. The dip-formed elastomeric films are free of pinholes and resistant to oxidative and ozone attack. The films are particularly suitable for use in products such as gloves, condoms, external catheters, catheter balloons, cuffs, dilatation balloons, instrument covers, and drains.

Patent CA-2056728-A1 (CA)
Inventor: SPENCER KEITH L
IPC: B60D1/58
Filed: 1991-11-29
Abstract: An articulated tractor has left and right laterally spaced apart, for-and-aft extending side frame members which are rigidly attached between front and rear drawbar supports. The tractor also includes left and right draft links, each draft link having a front end coupled to a corresponding one of the side frame members and a rear end for coupling to an implement.  A draft force sensing mechanism includes a displacement transducer mounted on one of the side frame members.  A lever is pivotally mounted near the transducer and carries a plunger or shaft which operatively engages the transducer.  A rod has a first end fixed to the other side frame member and a second end coupled to the lever so that changes in draft force cause deflection of the side frame members and movement of the lever relative to the transducer. The transducer responds by generating a signal representing the draft force.  Movement of the rod is amplified by the lever.

Title: Expandable heel shoe cover
Inventor: HIX HENRY M
IPC: A43B3/16
Filed: 1991-12-02
Abstract: ABSTRACT OF THE INVENTION        The present invention is directed to a shoe cover having a generally tube-like shape with an expandable heel portion to allow the shoe cover to better conform to the foot and ankle regions of the wearer despite the simple design of the invention.  The expandable heel portion is created by forming a plurality of folds across the width of the section of the material which forms the bottom portion of the shoe cover.  The folds are made in the general area of the shoe cover where the heel of the wearer would be positioned.   Upon donning of the shoe cover,  the heel portion expands as the folds unfold, thereby changing the generally tubular shape of the shoe cover into a shape which more easily conforms to the human anatomy.

Title: Laser gun ammunition measurement equipment
Inventor: YUHAS BARRY J
IPC: G01P3/68
Filed: 1992-02-20
Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus is described for measuring the velocity of an object by measuring the Doppler frequency shift of a reflected laser beam.  A laser beam is projected onto a target area which is moving with respect to the inertial frame of the laser transmitter and the laser receiver.  The reflected laser energy is mixed with a local oscillator beam and the mixed beam is focused onto a radiation detector.  The Doppler frequency shift is measured, thus indicating the object's velocity.  A sacrificial mirror is employed so that internal projectile velocity measurements may be made on the projectile.  The laser beam permits measurement both external and internal to the barrel for large and small caliber weapons.  Additionally, integration and differentiation means may be provided so that instantaneous position and acceleration data can also be generated for the projectile.

Abstract: Abstract of the Disclosure ANIONIC POLYMERIZATION MODIFIER    It has been unexpectedly discovered that various compounds, such as alkyl tetrahydrofurfuryl ethers, can be used to modify anionic polymerizations of conjugated diene monomers.  These modifiers can be used to polymerize isporene monomer into high 3,4-polyisoprene at excellent polymerization rates.  This is in contrast to the modifiers such as tetramethylethylen diamine which are typically used to modify such polymerizations.  This invention more specifically discloses a process for the synthesis of 3,4-polyisoprene which comprises polymerizing isoprene monomer in an organic solvent in the presence of a catalyst system which is comprised of (a) a lithium initiator and (b) ethyltetrahydrofurfuryl ether.

The instrument (20) includes a tubular carrier (32) storing the closure. The carrier (32) has a distally located free end to be extended through the opening (26). The closure (200, 300. 400, 500, 600, 700) comprises an anchoring portion (202, 302), a sealing portion (204, 304) and a thin filament (206) connected therebetween. The instrument (20) is operated to eject the anchoring portion (202, 302) of the closure through the incision or puncture (26) and to then draw that portion against the free end of the carrier (32). The instrument (20) is then withdrawn to pull the anchoring portion (202, 302) of the closure against the tissue contiguous with the incision or puncture. Further withdrawing of the instrument draws the sealing portion (204, 304) of the closure out of the carrier (32), whereupon it moves with respect to the anchoring portion and into engagement with the tissue contiguous with the open-ing on the opposite side of the anchoring portion to seal it.
