Title: Auger boot
Inventor: STARK LARRY
IPC: B65G33/24
Filed: 1996-01-19
Abstract: The present invention provides an auger boot for use with a grain auger particularly of the type for use when manually delivering grain to the inlet of a grain auger. The auger boot delivers grain to the inlet of a grain auger, can be easily placed in position and be removed when not needed. Use of the auger boot does not require modification of the grain auger. The auger boot is well suited for use when manually loading grain into the auger, and is well suited for use inside of grain bins. The auger boot comprises a grain accumulator and a grain hopper.  The grain accumulator is adapted to slide over and to surround the inlet end of the grain auger and a grain hopper is attached to the grain accumulator for delivering grain to the grain accumulator.
Patent CA-2170831-A1 (CA)
Title: Submersible canned motor mixer pump
Inventor: GUARDIANI RICHARD F
IPC: F04D29/04
Filed: 1996-03-01
Abstract: A mixer pump used in a waste tank for mobilizing high-level radioactive liquid waste having a column assembly containing power cables, a motor housing with electric motor means which includes a stator can of a stator assembly and a rotor can of a rotor assembly, and an impeller assembly with an impeller connected to a shaft of the rotor assembly. The column assembly locates the motor housing with the electric motor means adjacent to the impeller which creates an hydraulic head, and which forces the liquid waste into the motor housing to cool the electric motor means and to lubricate radial and thrust bearing assemblies. Hard-on-hard bearing surfaces of the bearing assemblies and a ring assembly between the impeller and electric motor means act to grind down large particles in the liquid waste flow. These larger particles are received in slots in the static bearing members of the radial bearing assemblies. Only solid waste particles smaller than the clearances in the system can pass therethrough, thereby resisting damage to and the interruption of the operation of the mixer pump.
Patent CA-2171135-A1 (CA)
Title: Bank note discriminator
Inventor: SCHWARTZ VLADIMIR A
IPC: G07D7/00
Filed: 1996-03-06
Abstract: The present invention is directed to a bank note discriminator having certain design features to make unauthorized withdrawal of an accepted bank note difficult. The passageway along which a bank note is processed includes a series of fixed blocking members with a camming surface one side and an undercut on the opposite side. Some of the blocking members are aligned with latches and others are located between latches. A bank note passing over the latches is deformed in a series of 'S' shapes across the bank note to clear the blocking members. It is difficult to impart this shape to a bank note once it has cleared the blocking members, thereby making unauthorized withdrawal difficult.
