Title: Kit for converting a motorcycle to a tricycle
Inventor: LEHMAN JOHN
IPC: B62K11/00
Filed: 1993-12-10
Abstract: An improvement in a kit for converting a motorcycle to a tricycle is described.  The kit includes a pair of swing arms having a first end and a second end.   Axle couplings are provided at the first end of each swing arm whereby the swing arms are secured to an axle which supports two wheels.  Pin receiving couplings are provided at the second end of each swing arm whereby the swing arms are pivotally secured by pins to a motorcycle frame.  The improvement is characterized by swing arms having a top surface and a bottom surface.  The axle coupling and the pin receiving coupling extend vertically from the top surface of the swing arms. The top positioning of the axle couplings and the pin receiving couplings leaves the majority of the top surface of the swing arms dropped below the level of the original floor boards of the motorcycle.  The swing arms can pivot as intended without their movement being impeded by the original floor boards.
Patent CA-2112609-A1 (CA)
Inventor: DESROCHERS EDDY
IPC: F16D67/02
Filed: 1993-12-30
Abstract: A brake and clutch assembly for electric motors  is  mounted  to  a  drive  shaft  of  such  an electric  motor.   The  drive  shaft  includes  a pin extending diametrically therethrough.   A brake pad provided around the motor shaft abuts on the motor side a fixed plate with the  following components being  provided  also  around  the  motor  shaft  in succession outwardly from the brake pad:  a drive disk, a clutch plate, a pulley, a compression spring and an end cap.   The drive disk includes a sleeve extending around the motor shaft.   The clutch plate and  the  pulley  are  slidably  mounted  around  the sleeve of the drive disk.  The drive disk defines a diametrical V-shaped recess which faces towards the brake pad with the pin extending in this recess. The spring biases the pulley and thus  the clutch plate  and the  disk drive  towards  the brake pad. Therefore,  when  the  motor  is  not  operating,  the drive disk is  frictionally retained into position against the brake pad.  The force of the spring and the friction between the pulley,  the clutch plate and the drive disk, in addition to the gearing-down mechanism between the pulley and the equipment end driven by the motor, prevent these components from rotating when the motor is not operating.  When the motor is  started,  the pin will climb out of  the bottom of the recess defined in the drive disk by pushing  the  drive  disk  against  the  compression spring, thereby axially also displacing slightly the clutch plate and the pulley, whereby the disk drive becomes spaced apart from the brake pad and can thus rotate  with  the  motor  shaft  while  frictionally rotatably driving the clutch plate and the pulley. During operation of the motor, the rotation of the pin drives the drive disk and of the components in frictional   engagement   therewith.      If   outside resistance forces are applied against the rotation of the pulley,  the clutch plate will slip thereby allowing the pulley to slow down or even stop while the clutch plate, the disk drive and the motor shaft continue to rotate thereby preventing damage to the motor.  The friction forces between the clutch plate and the pulley are sufficient in -order to operate the   pulley   under   normal   conditions   but   are insufficient to stop the clutch plate and thus the drive disk and the motor  shaft  if the pulley is forced to stop rotating.

Title: Oil Sand Extraction Process
Inventor: STRAND WILLIAM L
IPC: C10G1/04
Filed: 1994-05-06
Abstract: A method for processing lumps of oil sand containing bitumen to produce a bitumen froth and non segregating tailings of a solid material and a sludge. The method includes depositing the lumps of oil sand into a bath of warm water. The lumps are then conditioned by gently contacting them with the warm water to liberate and separate bitumen from the oil sand while minimizing the dispersal into the bath of fine material contained in the oil sand. Following conditioning, the solid material remaining after the liberation and separation of the bitumen from the oil sand is removed from the bath and collected for further processing. The warm water containing bitumen and dispersed fine material is also removed from the bath andcollected for further processing. Following removal from the bath, the warm water containing bitumen and dispersed fine material is separated into the bitumen froth and a suspension of dispersed fine material. The suspension of dispersed fine material is dewatered to produce the sludge, which is combined with the solid material to produce the tailings.

Inventor: BROWN ANTHONY K D
IPC: H03B27/00
Filed: 1992-12-09
Abstract: A resonant circuit comprises first (600) and second (600') amplifiers.  An input of the second amplifier is coupled to an out-put of the first amplifier, and an output of the second amplifier is cross-coupled to an input of the first amplifier. The first ampli-fier has a first gain and a 90 degree phase shift between its input and its output at a resonant frequency of the resonant circuit. The second amplifier has a second gain and a 90 degree phase shift between its input and its output at the resonant frequency of the resonant circuit.  The second gain is different from the first gain.  The resonant circuit can have a first port (Ap, An) and sec-ond ports (Bp, Bn) coupled to an input and an output respectively of one of the first and second amplifiers.  Because the gains of the first and second amplifiers differ, the gain from the first port to the second port of the resonant circuit will dif-fer from the gain from the second port to the first port.  This gain difference is useful for enhancing the quality factor Q of multiple resonator circuits constructed from such resonant circuits.
