Patent CA-2136856-A1 (CA)
Title: Sensor devices
Inventor: VADGAMA PANKAJ M
IPC: G01N27/26
Filed: 1993-05-13
Abstract: Sensor devices comprising enzyme electrodes incorporating a microporous membrane coated with the carbonaceous material known as "diamond-like carbon" (most conveniently deposited by decomposition of a hydrocarbon, induced by radiation or a high electric field). The membrane material is preferably a polycarbonate and its thickness preferably less than 10 microns, and the coating is preferably 0.01 to 5 µm thick. The preferred porosity is provided by pores of the order of 0.05 to 0.01 microns. The coated membrane imparts high resistance to fouling by contact with whole blood, extends the linearity of the electrode response over a substantially greater range, e.g. in the analytical determination of glucose in blood, and combines a high degree of restriction to passage of interferents while retaining high permeability to hydrogen peroxide and oxygen. Most conveniently used for amperometric measurements, especially using a Clark electrode pair, with an "active"  anode of platinum.

Title: High efficiency power supply and control brushless permanent magnet motor
Inventor: HOEMANN KEITH I
IPC: H02P6/08
Filed: 1995-05-03
Abstract: A simplified motor control for a brushless permanent magnet motor enables a relatively low voltage, high efficiency motor to operate from a high voltage source.  A capacitor is connected to the input side of the power supply portion of the motor control.  The capacitor acts as a lossless impedance and permits low voltage operation for the motor control.  In the preferred embodiment, the motor is connected to an H bridge controller output stage.  Rotor position is sensed by at least one Hall effect device.  The Hall effect device output is used to gate conduction of control transistors, depending upon rotor position.  The control transistors, in turn, control base drive to pairs of transistors of the H bridge output stage.          Preferably, the motor control input is a full wave bridge rectifier connected to an output capacitor.  The output capacitor provides dc bus voltage to the motor control.  Additional control devices may be employed on the input side of the rectifier to vary the voltage on the output side of the rectifier.  The design gives a very low cost motor and motor control combination, the combination having high reliability in applicational use.

Title: Method for multi-lateral completion and cementing the juncture with lateral wellbores
Inventor: JORDAN HENRY JOE JR
IPC: E21B43/10
Filed: 1995-09-14
Abstract: The present invention relates to two improved methods for multilateral completion and cementing (e. g. sealing) the juncture between primary and lateral wellbores. These two completion methods of the present invention address the issue of cementation of the lateral wellbores for the purpose of zonal isolation. It is desirable to have the ability to re-enter each lateral wellbore as well as maintain the option to perform any function that could be done in a single wellbore.      For this reason, cemented lateral wellbores are desirable so that normal isolation, stimulation or any other operation can be achieved.      The methods allow sealing and reworking of either wellbores with single laterals or multiple laterals and provide safe durable junctions therebetween.

Title: Bee disease control device
Inventor: POPODI JOHANN SR
IPC: A01K51/00
Filed: 1995-12-18
Abstract: Parasitic mites kill a large number of honey bees each year.  It is possible to destroy such mites using a miticide such as formic acid.  However, presently available methods of applying the miticide are unsatisfactory. This problem is overcome by a relatively simple box for receiving formic acid impregnated sawdust.  An air inlet opening is provided in one end of the box, and air outlets are provided in the top or cover of the box.  The box is placed in a hive opening.  The natural draft in the hive results in the flow of air through the box to pick up acid vapour for flow throughout the hive.  The outlet openings can be varied to control the quantity of acid entering the hive.

Title: Manicure machine
Inventor: JOSEPH JAMES R
IPC: A45D29/05
Filed: 1996-05-22
Abstract: A manicure device which is well suited for filing or buffing the convex top surfaces and the outer convex edges of fingernails and toenails includes a flexible, textured belt disposed in a cartridge which is detachably secured to a housing containing a high speed electric motor. The casing includes bearings over which the belt passes when the device is being used, and a belt opening which exposes a portion of the textured surface of the belt so that a fingernail can be pressed thereto. The manicure allows the belt to be pressed against a convex surface or edge of a fingernail or toenail, so that the belt will conform to the convex shape thereof and provide uniformly smooth filing or buffing. The cartridges are relatively inexpensive and easily replaced, which facilitates and promotes replacement of the cartridge whenever the machine is being used to file or buff the fingernails or toenails of a different person, whereby better hygiene is achieved.
