Patent CA-2079337-A1 (CA)
Title: Method and device for solid phase microextraction and desorption
Inventor: PAWLISZYN JANUSZ B
IPC: G01N35/04
Filed: 1991-04-02
Abstract: A device for carrying out solid phase microextraction is a fiber (6) contained in a syringe (4). The fiber can be solid or hollow. The syringe has a barrel (8) and a plunger (10) slidable within the barrel, the plunger having a handle (12) extending from one end of the barrel. A hollow needle (18) extends from an end (16) of the barrel opposite to the plunger. The fiber is contained in the needle. When the plung-er is depressed, the fiber extends beyond a free end (28) of the needle and when the plunger is in a withdrawn position, the fiber is located within the needle.  The syringe protects the fiber from damage. When it is desired to analyze a sample in a bottle having a septum, the needle is inserted through the septum and the plunger is de-pressed so that the fiber will extend into the sample. After one or two minutes, the plunger is moved to the withdrawn position so that the fiber will return to the needle and the syringe is withdrawn from the sample bottle. The syringe is then inserted through a septum in a gas injection port of a gas chromatograph. The plunger is again depressed so that the fiber will extend into the gas chromatograph and an an-alysis of the components on the fiber is carried out. Then, the plunger is moved to the withdrawn and the syringe is withdrawn from the injection port.  Previously, sam-ples were analyzed using liquid-liquid extraction or using cartridges. Both of these methods are relatively expensive and time consuming. Both of these methods also require the use of solvents which can be difficult and expenssive to dispose of.

Title: Casing assembly for a down-the-hole drill tool
Inventor: YOUSEF FAISAL J
IPC: E21B17/10
Filed: 1991-11-27
Abstract: A percussion drill includes a reciprocating piston surrounded by a cylindrical casing. Disposed at opposite ends of the cylindrical casing are replaceable hollow cylindrical wear sleeves. The wear sleeves are mounted within recesses formed in the outer surface of the casing. Each wear sleeve has a thickness equal to the depth of its respective recess. A longitudinal inner end of each wear sleeve is spaced longitudinally from an end surface of the recess, and a flexible seal is situated between those opposing ends.  The wear sleeves can be replaced after being worn by the abrasive environment encountered in the hole being drilled. The wear sleeves may be formed of a more wear resistant material than the casing.
Patent CA-2097726-A1 (CA)
Inventor: MUCKENFUHS DELMAR R
IPC: B65D85/07
Filed: 1991-11-29
Abstract: A more environmentally compatible package (10) containing one or more stacks of compressed flexible articles (20). For products such as single use absorbent baby diapers, catamenial pads, incontinent briefs and the like, the degree of compression within the bag may be as much as 50 % or more when compared to the uncompressed thickness of the articles.      In a particularly preferred embodiment, the bag totally encloses a stack of compressed flexible articles and exhibits a substantially rectilinear shape. The bag preferably includes an integral carrying device (71).      The side panels (30 and 31) and the front and back panels (40, 41) of the bag are subject to tension imposed by the stack of compressed flexible articles. A line of weakness at least partially spanning a tensioned side panel of the bag is provided and functions as an opening device. The line of weakness is coated with a layer of reinforcing material preferably comprised of polyvinyl alcohol to prevent premature rupturing of the opening device. The opening device (17) allows the compressive forces acting upon the flexible articles contained in the bag to be at least partially released when the opening feature is activated by the end user. Partial separation or complete removal of a portion of the tensioned side panel (17) of the bag allows the coinciding portion of the stack of compressed articles to project in a fan-like array through the aperture thus created to permit easy one-at-a-time or multiple removal. Polyvinyl alcohol of the type used to reinforce the opening feature may, if desired, also be used as a sealant for assembling the bag and to provide additional support for the carrying device.

Title: Vehicle crash energy absorbing mechanism
Inventor: HANCOCK MICHAEL T
IPC: B62D1/19
Filed: 1993-07-08
Abstract: ABSTRACT            VEHICLE CRASH ENERGY ABSORBING MECHANISM            A vehicle crash energy absorbing mechanism incorporated in a steering column structure mountable to a break away mounting, the structure including an inner steering shaft which is drivably coupled by a splined arrangement to an outer shaft.   The inner shaft has an energy absorption member in the form of a tube which surrounds a pin which is mounted diametrically through the inner shaft.   A crash induced force on the column structure causes the outer shaft to be forced relatively towards the tube, thereby inducing an interaction between the pin and tube,  the latter being deformed thereby to achieve the requisite energy absorption.            In an  alternative embodiment,  the  splined outer shaft itself  acts  as  the  absorption  energy member,  the  pin deforming the splined arrangement.            (Fig. 2)

Title: Sizing separation of sewage particles in an improved automedium cyclone
Inventor: VISMAN JAN
IPC: C02F11/00
Filed: 1994-02-04
Abstract: A method is provided for performing a granulometric separation and recovery of solids from a mixture of solids and water introduced to a modified form of a known Automedium Cyclone apparatus. In particular, the vortex finder of the cyclone is spaced sufficiently above the tri-conical bottom to separate and recover a first fraction of fine particles as an overhead product from the vortex finder, the spacing being required for rejection of the coarser fractions. A second fraction of fine particles is recovered from the lowest conical section of the tri-conical bottom, for transport to the overhead product, resulting in an underflow product substantially devoid of fines. A dense, rapidly circulating bed of solids developed in the middle conical section is utilized to shatter solids agglomerations to liberate contained liquid and variously sized particles and fibers. The method is particularly applicable to the treatment of sewage, acting to separate any fibrous mass into discrete fractions for granulometric separation and recovery.
