Patent CA-2056316-A1 (CA)
Inventor: SHIMAMURA TAKEO
IPC: H02P9/00
Filed: 1991-11-27
Abstract: This invention proposes an operating control device and method for a winding type induction machine that ensures that the harmonic components naturally present in the primary voltage of a winding type induction machine, do not correspond to the antiresonance point of the impedance characteristic of the transmission system to which the winding type induction machine is connected. Those corresponding harmonic components are eliminated from the primary winding of the winding type induction machine by applying appropriate voltage command values to a PWM controlled inverter if there is distortion of the primary voltage or if the transmission system is being changed over.

Title: Fluidic actuator scraper seal
Inventor: ELLIOT ROBERT A
IPC: F15B15/14
Filed: 1991-11-28
Abstract: Dual "U" cup seals are utilized in conjunction with conventional seals as fluidic actuator shaft scrapers for actuators operating in contaminated environments. The seals are installed in serial spaced relation on the low pressure side of the conventional seals such that they scrape contaminants off of the shaft as well as seal against the ingress of contaminants to the high pressure seal area. The scraper configuration may also be of benefit in piston bore seal systems which operate in contaminated fluid environments.

Inventor: PIKE CLINTON W
IPC: E04D5/02
Filed: 1992-05-11
Abstract: Abstract of the Disclosure Asphaltic roofing material, such as roll or shingle roofing, employs Class F fly ash as the filler to the asphaltic base material.  The fly ash is more readily heated than conventional crushed limestone which has been used as a filler, and further promotes a more rapid cooling of the composite asphaltic web prior to rolling or cutting into shingles.  The Class F fly ash comprises between 40% and 70% of the hot asphaltic mixture, by weight.  It may be delivered to the roofing plant in a state of elevated temperature from the fly ash source to reduce the requirement for preheating the fly ash or eliminating the preheating step altogether.  The slightly acidic content of fly ash discourages the growth of fungus and mold on the roofing material in hot and humid climates, and the resulting shingle has greater overall flexibility and resistance to cracking at low temperatures, as compared to a shingle in which crushed limestone is used as the inert filler.

The boron compound and the inorganic phosphorus acid are preferably co-present during the heating. However either such substance can be added and subjected to the heating step after the other provided that the conditions used result in the formation of a clear, liquid composition.
