Patent CA-2123673-A1 (CA)
Inventor: YAMADA MITSUO
IPC: C09D175/04
Filed: 1994-05-16
Abstract: Diglycidyl ether epoxy resins are reacted with a prepolymer  produced  from  an  organic  diisocyanate  and  a bifunctional active hydrogen compound having a soft segment whose terminal isocyanate groups have been blocked to chain-extend the epoxy resin with the prepolymer.   The chain-extended epoxy resin is then reacted with a cationic active hydrogen compound alone or in combination with an aliphatic monoalcohol, alkylphenol, glycol monoether or bisphenol to open the terminal epoxy rings of the chain-extended epoxy resin.  The modified epoxy resin thus produced is dispersed in an aqueous medium containing a neutralizing agent together with a crosslinker to give a cathodic electrodeposition paint having improved impact strength and other properties.

Title: Method and apparatus for securing a flexible sheet to a rotatable supporting surface
Inventor: WHITESIDE GEORGE D
IPC: B65H5/12
Filed: 1995-05-03
Abstract: In high speed laser imaging, it is important to ensure that the film medium is properly aligned on the rotary support drum to prevent errors in the images obtained.  This is achieved in one embodiment by a clamping mechanism which includes a pivotal clamp that has a center of gravity which pivots as the drum is rotated to drive the clamping edge thereof against the medium and the drum with a force which corresponds to the centrifugal acceleration of the drum.  The centrifugal clamp is constructed so that it will not bend or push the medium away from the clamp's pivot axis to thereby cause the medium to otherwise buckle or bulge from its precision wrapped position.  In another embodiment, the clamp is constructed to pull the edge of the medium toward its pivot axis so as to cinch the sheet on the drum surface and thereby even more securely wrap the medium on the drum.

Patent CA-2171216-A1 (CA)
Title: Laser sensor capable of measuring distance, velocity, and acceleration
Inventor: WILSON MARK L
IPC: G01S7/491
Filed: 1994-09-28
Abstract: A light based distance, velocity and acceleration sensor which uses phase difference to determine the desired measurement.  A laser signal is modulated by an oscillator signal and reflected off an object to a signal receiver. The reflected laser signal and the oscillator signal then pass through a dual path conditioning circuit, where the path lengths and circuit elements of the two paths are identical to cancel the effets of propagation delays in an output signal. The conditioned signals are passed through a phase comparator, to produce a signal indicative of the phase difference between the oscillator signal and the reflected laser signal. The phase difference is directly proportional to the distance between the sensor and the object.

Abstract: A bucket-angle controlling method which is capable of automatically turning off the bucket-angle-maintaining control to maintain the bucket of a hydraulic shovel (12) at a specified position. When the open surface of the bucket (15bk) comes close to the horizontal plane bucket angle (.theta. bk), which is an angle of the bucket (15bk) open surface with respect to the horizontal plane, is maintained constant in order to prevent load from being spilled at the time of unloading and so forth. When bucket angle (.theta. bk) is greater than a preset standard value (.theta. bkset), a controller judges that bucket (15bk) is performing excavation. Then, the bucket-angle-maintaining control is temporarily deactivated to permit excavation to be performed through manual control.
