Patent CA-2081429-A1 (CA)
Inventor: KACZMARCZYK EDWARD T
IPC: E02F3/36
Filed: 1992-10-26
Abstract: A tractor-mounted loader has a quick coupler mounted to forward ends of the boom arms thereof.  The quick coupler includes a pair of attachment holders having their lower ends respectively pivotally connected to the pair of arms and selectively pivotable by a pair of attachment tilt cylinders. An attachment in the form of a bucket includes a pair of connecting brackets including pins engageable by recesses in the upper ends of the holders and receptacles for receiving coupler elements carried by the holders.  A pair of latch mechanisms are respectively carried by the pair of brackets and include spring-loaded latch pins which normally assume a latch position blocking passage of the coupler elements to or from the receptacles but which include ramp surfaces that cooperate with ramp surfaces of the coupler elements to cause the pins to be automatically moved from their latch positions to permit passage of the coupler elements into the receptacles during mounting of the attachment to the attachment holders. The latch pins may be manually moved to an unlatch position from which they are automatically released by being contacted by wedges carried by the holders when the latter are moved to a position disposing the coupler elements free of the receptacles during detachment of the attachment from the holders.  An alternate embodiment shows the coupler elements formed by the mounting brackets and the receptacles formed by the holders with the latch mechanisms being mounted to the holders.

Title: Low-sulfur diesel fuels containing organometallic complexes
Inventor: DALY DANIEL T
IPC: C10L1/18
Filed: 1992-04-15
Abstract: This invention relates to low-sulfur diesel fuels which are useful with diesel engines equipped with exhaust system particulate traps. These fuels contain an effective amount of an organometallic complex to lower the ignition temperature of exhaust particles collected in the trap. The sulfur content of these diesel fuels is no more than about 0.1 % by weight, preferably no more than about 0.05 % by weight. The organometallic complex is soluble or stably dispersible in the diesel fuel and is derived from (i) an organic compound containing at least two functional groups attached to a hydrocarbon linkage, and (ii) a metal reactant capable of forming a complex with the organic compound (i), the metal being any metal capable of reducing the ignition temperature of the exhaust particles. The functional groups include =X, -XR, -NR2, -NO2, =NR, =NXR, =N-R*-XR, (I), (II), (III), -CN, -N=NR and -N=CR2; wherein X is O or S, R is H or hydrocarbyl, R* is hydrocarbylene or hydrocarbylidene, and a is a number (e.g., zero to about 10). Useful metals include Na, K, Mg, Ca, Sr, Ba, Ti, Zr, V, Cr, Mo, Mn, Fe, Co, Cu, Zn, B, Pb, Sb, and mixtures of two or more thereof. This invention is also directed to methods of operating a diesel engine equipped with an exhaust system particulate trap using the foregoing low-sulfur diesel fuels.

Abstract: Microcapsules, a process for their preparation and their use Abstract This invention relates to a process for encapsulation and particularly for the preparation of microcapsules having a capsule wall of a solid polymeric substance enclosing a water-immiscible material, which process comprises preparing a solution of a first reactive component required to form the capsule wall in the water-immiscible material, then dispersing the mixture in an aqueous medium containing a surfactant which is a salt of a partial ester of a styrene-maleic anhydride copolymer, to form an oil-in-water emulsion, and subsequently adding a second reactive component required to form the capsule wall which is complementary to the first one and reacts with it under the mixing conditions, whereby a solid polymeric wall is formed about the dispersed water-immiscible material. The resulting stable aqueous suspension of microcapsules can either be used directly or after dilution with water, or the microcapsules can be separated from the aqueous phase.

Patent CA-2093590-A1 (CA)
Inventor: BARWICK ELVIN F
IPC: D03D37/00
Filed: 1993-04-07
Abstract: The present invention entails a method and apparatus for weaving an indicia such as a trademark, symbol or design into a tubular fabric. About a selected warp yarn segment of the tubular fabric, for each warp yarn increment, two warp yarns are actually directed into the loom, one warp yarn being a base yarn while the other warp yarn is an indicia forming yarn. The loom is provided with a warp yarn selector that for each pair of base and indicia forming yarns, it selects one and only one of the pair to be interwoven with a weft yarn. The non-selected yarn is essentially positioned such that it is not woven with the weft yarn and runs in a floating or unwoven fashion along the inside wall of the tubular fabric being woven. To provide a selected indicia interwoven in the tubular fabric, the selector is controlled in such a fashion that it causes indicia forming yarns to be woven in areas. calling for the indicia background and base warp yarns to be woven in areas that call for the base yarn as a background. As noted, in all cases the non-selected warp yarn of the pair will be floated to run along the inside wall of the tubular fabric.

IPC: A61L27/36
Filed: 1992-05-14
Abstract: A method is disclosed for preparing a transplantable tissue which has been cryopreserved with an intracellular cryoprotect-ant and then thawed. After thawing, the tissue is treated with a diluent (or eluent) solution to reduce the level of cryoprotectant in the cells to a substantially non-toxic level. This is conducted using a single dilution step. Cryoprotectants which are removable in this manner include dimethylsulfoxide, glycerol, propanediol and other compounds which penetrate the cells. The dilution step does not require end point titration and can be conducted over a time period greater than about 5 minutes.

Abstract: A polymeric composite structure having a polymeric shell layer with a finish-side and a non-finish side and a cross-linked thermosetting polymeric backing layer and method of manufacturing thereof is provided. The cross-linked thermosetting polym-eric backing layer is simultaneously molded to conform to the shape of and bonded directly to essentially the entire non-finish side of the polymeric shell layer. The method includes forming the polymeric shell having a finish-side and non-finish side into a suitable shape, placing the shell into a mold, and introducing an uncured blended mixture of unsaturated thermosetting polymer-ic backing material and cross-linking promoter into the mold to force the backing material to directly coat the non-finish side of the shell. Curing the molded thermosetting polymeric backing material at a suitable temperature and sufficient time allows hard-ening and cross-linking of the thermosetting polymeric material and bonding directly to the non-finish side of the polymeric shell to permit demolding of the composite structure without damage.
