Patent CA-2113101-A1 (CA)
Inventor: GOUMENIOUK ALEXANDER
IPC: C12Q1/06
Filed: 1992-07-08
Abstract: Methods for detecting granulocytes and for providing an at least semiquantitative indication of granulocyte level and kits for implementing those methods. A blood sample is drawn, and components that might interfere with the assay are removed and/or neutralized. Granulocytes present in the sample are then disrupted to release intracellular myeloperoxidase, and the sample is contacted with a peroxide and a chromogenic donor dye. The myeloperoxidase enzyme catalyzes hydrogen peroxide-involved reactions which result in the dye changing color if, and to the extent that, granulocytes are present in the blood sample.

Title: Storage and display assembly and method for constructing same
Inventor: DARDASHTI SHAHRIAR
IPC: A47F7/00
Filed: 1994-06-24
Abstract: An assembly for storing and displaying discs, cassettes, game cartridges, tapes and/or the like, including an elongated, straight side-walled storage unit forming one or more vertically upright columns of longitudinally-spaced storage slots. First and second side members are secured to the opposite lower sides of the storage unit and extend out from them. A top member is secured to the storage unit and extends up from it.      The side members and top member are configured such that they together with the storage unit define in front view a readily-recognizable outline of a common (non-storage unit) object, such as a guitar or other musical instrument. The slots or ribs of the storage unit define, when the object is a stringed musical instrument, the frets thereof. An interesting, attractive and readily-identifiable storage and display assembly is thereby defined. The side and/or top members can also provide surfaces to which holders for holding special tapes or cases are face mounted. The entire assembly can be mounted flat against a wall or upright to a base.      When mounted to a base, the side members themselves can be directly secured to the base to further brace and support the elongated storage unit upright on the base.      Alternatively, another similar storage unit can be mounted back-to-back to the storage unit, both mounted to a rotatable base and the top member used as a turning member for turning the units on the base.

Patent CA-2133118-A1 (CA)
Title: Battery recharger
Inventor: DECKERT CLINT
IPC: H02J7/00
Filed: 1994-09-28
Abstract: ABSTRACT A battery charging device is provided which uses a charging circuit monitored and controlled by a current detector and a logic circuit.  The charging circuit has a voltage source capable of providing a maximum charging voltage and a maintenance voltage to a  battery.   The current in the charging circuit is monitored by the current detector.  As the battery is charging the current in the charging circuit eventually drops below a predetermined threshold  current  at  which  time  the  current  detector signals a timer.   Upon receiving this signal from the current  detector,  the  timer  provides  an  output  which maintains  the  voltage  source  at  the  maximum  charging voltage until a predetermined time interval has expired. When the time interval expires, the timer output changes which lowers the voltage provided to the battery to a level which maintains the charge in the battery without drying out the battery.

Title: Dc current sensor
Inventor: KAWAKAMI MAKOTO
IPC: G01R15/18
Filed: 1994-10-28
Abstract: ABSTRACT OF THE DISCLOSURE It is an object of the present invention to provide a sensitive DC current sensor, which has a relatively simple construction and a detecting capability with a good linearity, against current variations in a wide range from a microscopic current to a relatively large current (e.g. about 0.2 A to 20 A). In the configuration, wherein an exciting coil and a detecting coil are wound in a toroidal shape around a core consisting of an annular soft magnetic material, when a triangular waveform exciting current which produces a magnetic field exceeding a coercive force of the core is applied to the exciting coil, a direction of the magnetic flux in the core is inverted, whereby an absolute value and a direction of a DC current flowing through a lead wire being detected can be detected, by detecting an inverse timing by a pulse voltage produced in the detection coil for comparison measurement of the pulse intervals.
Patent CA-2136604-A1 (CA)
Inventor: GOOD ROBERT H
IPC: A63B53/04
Filed: 1994-11-24
Abstract: A golf club head has a golf club body which consists entirely and exclusively of a solid, unitary mass of polymethylmethacrylate (acrylic), the head being completed by a metal insert in the body which receives the end of the club shaft. The acrylic body is made by an injection molding process. The acrylic charge can be unadulterated, for producing a completely clear club body, or can be provided with a dye so that the club body can be given any desired color, while still remaining transparent. In addition to anesthetically pleasing appearance, since the club body is made out of a solid mass of material, a cleaner transfer of energy occurs from the club shaft to the face of the club head which strikes the golf ball, thereby producing a longer and more accurate drive.
