Patent CA-2063462-A1 (CA)
Inventor: MAY R ELWIN
IPC: A01B19/08
Filed: 1992-03-19
Abstract: A cart or "caddy" is provided for operation and transport of one or more chain harrows, the cart consisting of a frame running on a pair of road wheels.  Different harrow mountings can be mounted on the frame, all of which include a draw bar to which the harrow is attached for operation.  All of the mountings enable the draw bar to be lifted from the ground and then the body of the harrow to be engaged by one or more spaced cross bars parallel to the draw bar and over which the harrow is draped to store it and permit it to be transported on the cart out of contact with the ground.  Some of the mountings are pivoted to the cart frame about an axis that in the stored position is vertical, so that the mounting and harrow can be turned longitudinally to reduce the effective width and permit the use of harrrows that would otherwise be too wide to be moved over public roads.  Wider arrangements use two harrows that operate side-by-side on mountings that are pivoted individually so that they can be turned to be parallel to one another in the stored transportable position; such mountings employ extra outrigger supporting wheels and tension cables to keep them parallel.

Title: Cdna encoding the rat d1 dopamine receptor linked to adenylyl cyclase activation and expression product
Inventor: SIBLEY DAVID R
IPC: C07K16/00
Filed: 1991-07-02
Abstract: Molecular cloning and expression of the D1 dopamine receptor protein is linked to the activation of adenylyl cyclase activity.  By constructing cell lines that express the D1 receptor, the affinities and efficacies of agonist and antagonist drugs with the receptor can be assessed. A recombinant DNA construct includes a vector and a DNA fragment encoding the D1 receptor. A host cell is transformed with a recombinant DNA construct, so that the DNA  fragment is expressed and the D1 receptor is produced. Suitable expression systems include eukaryotic and procaryotic cells, especially mammalian cells such as rat or human. Additionally, for diagnostic purposes, antibodies to the D1 receptor can be prepared by producing all or a portion of the receptor protein and injecting these into various types of mammals. Using the resulting antibodies, expression of the D1 receptor cDNA in cells can be measured.

Title: Operation of vertical shaft furnaces
Inventor: WESTLEY DAVID R
IPC: F27B1/00
Filed: 1993-01-29
Abstract: ABSTRACT OPERATION OF VERTICAL SHAFT FURNACES   A hot coke bed 32 is established at the bottom of a vertical shaft furnace, e.g. an iron melting cupola 2.  The cupola 2 is then charged with alternate layers 34 and 36 of ferrous metal and coke respectively.  Burners 18 burn hydrocarbon fuel in the presence of a stoichiometric excess of oxygen-enriched air and thus form a hot gas mixture including oxygen.  The hot gas mixture passes upwards through the shaft 4 of the cupola 2 thereby providing sufficient heat to melt the ferrous metal.  Molten ferrous metal flows downwards under gravity into and through the coke bed 32 and may be removed through a tap hole 28.  At least one jet of oxygen is injected into the hot coke bed 32 so as to maintain it at a temperature sufficient to superheat the molten metal.  Preferably a fan 11 is operated to dilute with air the combustion gases above the level of the charge in the shaft 4 and thereby create secondary flames.  No air blast is supplied to the cupola. A significant degree of superheating can be achieved while keeping down the proportion of environmentally undesirable components (i.e. particulates and carbon monoxide) in the gas exhausted from the cupola.
