Patent CA-2013089-C (CA)
Inventor: OGISHI HIDEO
IPC: B32B15/08
Filed: 1990-03-26
Granted: 1994-04-05
Abstract: ABSTRACT OF THE INVENTION The improved corrosion-resistant steel plate with an organic coating comprises a steel plate having a zinc or zinc alloy plate layer which is overlaid with a chromate film which in turn is coated with an organic resin paint film. The organic resin coat comprises an epoxy resin which is prepared by reacting with an isocyanate compound and has a dialkanolamine incorporated into its bisphenol A skeleton, and silica.  The dialkanolamine combines with a urethane-modified epoxy resin to provide satisfactory curability at low temperatures; at the same time, it combines with the silica to provide a satisfactory film reinforcing effect. The organic coat formed of this composition can be effectively cured at low temperatures and yet it will neither dissolve nor soften upon swelling under the action of the alkali that is generated during cationic electrodeposition at the interface between the electrodeposited film and the organic coat.  Thus, the organic coat has good paint adhesion, high corrosion resistance, as well as good workability and as-worked corrosion resistance and makes the steel plate suitable for use as an automotive part after painting.

Granted: 1995-04-18
Abstract: A seed distribution system includes an upright main hopper for containing a mass of seeds.  The input end of a seed tube projects into the lower portion of the hopper near the bottom of the seed mass.  The input end of the seed tube is located within the output end of an air supply tube and terminates inwardly of the supply tube. The seeds in the main hopper are pneumatically captured by creating a generally dome-shaped area in the seeds adjacent the input end and sweeping seeds from the area into the input end.  The captured seeds are propelled through the seed tube to a secondary hopper adjacent a seed metering device.  To provide automatic level control, the delivery end of the seed tube is supported within the secondary hopper so that, as the seed level rises in the hopper, air flow and thus seed delivery rate will decrease.  Automatic seed distribution from the bottom of the central hopper to the secondary hopper is accomplished simply and reliably with no moving parts other than those associated with the source of air.

Title: Process for extending the life of a displacement plating bath
Inventor: VITALE AMERICUS C
IPC: C23C18/31
Filed: 1992-11-18
Granted: 1998-02-17
Abstract: A stabilized spray displacement tin plating process of copper printed circuit innerlayers is disclosed for the manufacture of multilayer printed circuit boards. During prolonged use of spray tin plating, the plating solution becomes saturated with cupurous thiourea complex which precipitates interfering with spray nozzles and other mechanical components.  The tin plating solution is stabilized by removing portions from the reservoir before saturation is reached, selectively precipitating the thiourea complex, and returning the remaining solution back to the reservoir.  The precipitated cupurous thiourea complex is redissolved in acid and either disposed of by conventional waste treatment or the acid solution can be electrowinned to reclaim copper and oxidize thiourea to form a more acceptable acid solution for waste treatment. Preferably, the thiourea is isolated from the anode during electrowinning, so that the acid thiourea solution formed may be used to partially replenish the tin plating solution in the reservoir.  By such periodic removal of the complex, the plating bath is stabilized and its useful life is extended dramatically.

Granted: 2001-02-20
Abstract: According to the cellular mobile radiotelephone call access method of the present invention, a directed retry message is sent in response to an attempted call access in a first cell experiencing congestion. A subsequent retry and a second cell of the attempted call access is detected, and, if a traffic channel allocated to the first cell is then available, a traffic channel allocated to the first cell is assigned from the second cell. The call is therefore established in the original cell more often, and interference is reduced.
