Patent CA-2123223-A1 (CA)
Inventor: EVANS RONALD M
IPC: A61K31/20
Filed: 1992-12-18
Abstract: In accordance with the present invention, there are provided methods to modulate processes mediated by retinoid recep-tors, employing high affinity, high specificity ligands for such receptors. In one aspect of the present invention, there are provided ligands which are more selective for the retinoid X receptor than is retinoic acid (i.e., rexoids). In another aspect of the present invention, alternative ligands (other than retinoic acid) have been discovered which are capable of inducing retinoic acid receptor mediated processes. In yet another aspect, methods have been developed for the preparation of such retinoid receptor ligands from readily available compounds.

Abstract: A method of preparing a catalyst particularly useful in the reaction of ethylene, oxygen and acetic acid in the vapor phase to form vinyl acetate comprises impregnating a porous support with water soluble salts of paliadium and gold, fixing the palladium and gold on the support as water insoluble compounds by contacting the salt-impregnated support with a reactive solution in two separate fixing stages wherein the treated support is dried and allowed to stand prior to treatment in the second stage to precipitate the insoluble compounds on the support and reducing the insoluble compounds to free palladium and gold. The catalysts prepared in this manner have been shown to provide improvement with respect to reduced selectivity to CO2 during the vinyl acetate forming reaction.

Abstract: A self-propelled core-cutting apparatus is used to cut circular slots in pavement extending about manhole castings and the like to permit castings and surrounding cores of pavement to be removed quickly and easily for such purposes as elevating the level of manhole castings to align with new pavement.  The appa-ratus has a transport carriage to which are connected 1) a large diameter,  generally  cylindrical  core-cutting  bit,  2)  power-operated support and drive systems mounting the bit for vertical and rotary movement relative to the carriage along and about a vertically extending center axis, and 3)  a power-operated sta-bilization system that makes use of the weight of the apparatus in maintaining desired positioning of the apparatus during cut-ting operations.  Support for the core cutting bit is provided by a telescopically extensible array of cage-like structures that extend substantially concentrically about the center axis, inclu-ding an outer cage that is rigidly connected to the carriage, and an inner cage that is movable vertically relative to both the outer cage and the bit.  Job site positioning of the apparatus is effected by using lever or joystick controls to operate a fluid-motor-driven power-steerable wheel that also serves as one of three vertically movable components of the power-operated stabi-lization system.  Preferred practice of the invention also makes use of other disclosed features.

Title: Frame for agricultural cultivator
Inventor: BALMER CHARLES
IPC: A01B61/04
Filed: 1995-12-20
Abstract: An agricultural cultivator includes a single elongate tubular tool bar of circular cross section which is split into a centre section and two wing sections interconnected with the centre section at outer ends thereof through pivot couplings.  The center section of the tool bar is mounted on two ground wheels and the outer end of each wing section is mounted on a respective one of a pair of ground wheels.  Each ground wheel is connected to the tool bar by a respective brace.  The ground wheels are aligned so that there axes of rotation lie on a common line forwardly of the tool bar. The braces are interconnected with a hitch frame for pivotal movement relative to the hitch frame about pivot pins defining a common pivot axis parallel to the tool bar and located between the tool bar and the common line of the ground wheels so that rotation of the braces causes the tool bar to move forwardly while the ground wheels move rearwardly under the toolbar.  The rotation of the tool bar through approximately 90° lifts the cultivator shanks mounted on individual tool frames carried from the tool bar so that the tool frames stand vertically upwardly from the tool bar in a transport position. In the operating position slight movement of the braces adjust the vertical height of the tool bar from the ground for adjusting the depth setting of the cultivator shanks.
