Patent CA-2051171-A1 (CA)
Title: Lipase-surface complex and methods of formation and use
Inventor: MIZUSAWA EUGENE A
IPC: C12S11/00
Filed: 1991-09-11
Abstract: ABSTRACT           Methods for treating surfaces with lipase to provide  an  enzyme-surface  complex  and  surfaces  so treated  facilitate  oil  removal.    One  such  treated surface is a fabric with lipase sorbed onto the surface. A  preferred  sorbed  lipase  is  isolatable  from  a Pseudomonas organism or clone.   Treated fabrics have substantial  hydrolysis  activity  for  oil  stains  and perhydrolytic activity  for oil stains,  have altered surface wettability, and retard oil and hydrolysis by-produce  redeposition  in  the  presence  of  aqueous solutions.  The sorbed lipase is resistant to removal during  fabric  laundering  and  retains  substantial hydrolytic activity even with exposure to drying at elevated temperature.  The hydrolytic activity of the lipase-fabric complex persists during storage or wear. Hydrolysis by-products are removable during laundering at basic pH or in the presence of surfactant.
Patent CA-2051263-A1 (CA)
Title: Interrupter switch with coordination of disconnect and interrupter linkage
Inventor: ROGERS EDWARD J
IPC: H01H33/12
Filed: 1991-09-12
Abstract: An arrangement is provided that includes a coordinating input for a mechanism of an interrupter switch; the coordinating input being derived from sensed movement of an element away from a first position and toward a second position. The coordinating input is utilized to trip the interrupters if they are closed. In a specific arrangement, a stored-energy mechanism is tripped to provide opening and closing of the interrupters via a high-speed interrupter drive train. The tripping arrangement is operable via a first input to cause movement of a latch member to release the stored-energy mechanism to operate the interrupter drive train. The first input may be actuated via open or close instructions, including both local and remote capabilities. The latch for the stored-energy mechanism is reset after each actuation. An output shaft of the mechanism is connected to drive the interrupter drive train. Both opening and closing are accomplished via rotation of the output shaft in the same direction. An open/close sensing input for the interrupter drive train is derived from the position of the output shaft. In a specific embodiment, the sensed movement of the element corresponds to the movement of a disconnect linkage away from a closed position.

Title: Direct current motor utilizing back electromotive force
Inventor: NAHIRNEY PETER MICHAEL
IPC: H02K29/00
Filed: 1991-06-11
Abstract: A dual voltage direct current permanent magnet brushless motor operated by sequential and alternate pulses to two rows of stator coils (3, 9) radially and equally positioned in the stator (5) assembly to interact with two rows of permanent magnets (7, 10) equally spaced on the rotor (1). All the permanent magnets in one row are poled opposite to all the permanent magnets in the other row and total one less than the number of stator coils in each row.  The reversal of poles of one row of permanent magnets on the rotor (1), along with the equal and opposite voltage permits the back electromotive force from a de-energizing stator coil in the first row to feed energy to the next stator coil positioned on the opposite site of the rotor (and vice versa) which interact with the reverse poled permanent magnet to produce only useful torque.  Additional energy will be drawn from the battery as required to maintain the speed and torque requirement of the motor. The pulse to each stator is controlled by individual photocell detectors or Hall effect devices. The arrangement and control of the stator coils also permits power generation in the braking mode. The dual equal and opposite drive voltage permits the use of identical solid state switching devices in each side of the circuitry as well as utilization of the lowest possible peak inverse voltage rated devices as a result of the connection used between the stator coils.
