Patent CA-2245056-A1 (CA)
Inventor: DIBIASI MICHAEL A
IPC: A61B5/15
Filed: 1998-08-14
Abstract: A lancet assembly includes an injection molded housing having a 30 Gauge metal stylet that is inserted and bonded therein. Since no molding forces are ever applied to the 30 Gauge stylet the resulting lancet assembly is the first having an entirely straight small diameter stylet. Therefore, the lancet assembly with this small straight 30 Gauge stylet causes less pain than any currently available larger gauge lancets. In addition, when the 30 Gauge stylet is lubricated after being mounted in the housing the lancet assembly not only causes less pain but has also been found to provide improved blood flow from the very small puncture wound.

Title: Centrifugally controlled countersinking and deburring tool
Inventor: LIPPUNER WERNER
IPC: B23D79/00
Filed: 1998-09-10
Abstract: A countersinking and deburring tool for deburring, chamfering, and countersinking of partially and fully penetrating holes with a rotationally actuated housing and at least one blade which can move within a housing shaft and perpendicular to the rotational axis of the housing, provides that, depending on the direction of rotation of the drive, the blade is withdrawn into the housing shaft or extended out of the housing shaft (reverser operation), and the displacement drive for the blade consists of a rocker which is mounted so that it can rotate in the housing and is rotationally actuated, which acts on the blade with at least one actuation pin. According to the invention the rocker's rotary actuator consists of at least one centrifugal weight arranged in the housing so that it can move diametrically, whose diametric displacement in the housing is converted into a rotational motion on the rocker through a form-fit guide.

Title: Gutter trolley with bag
Inventor: DABROWSKI JERZY Y
IPC: E04D13/064
Filed: 1998-10-01
Abstract: A combination trolley and bag to receive and hold leaves and debris cleaned from a rain gutter (eavestrough). The trolley includes a pair of rolling sheaves that ride on the outside edge of the gutter to transport leaves and debris from the initial point to the next section to be cleaned or until the bag is full. Safety flaps attached to the same shaft as sheaves work as a stopper to keep the device in place in case the sheaves slide off the gutter edge. The safety flaps spin freely to by pass any obstacle in the gutter such as brackets, holding nails, or fastening devices which secure the gutter to the roof. Two support arms, which hold and secure the bag, hinge to an up position for flat and easy storage. When lifting one of the support arms and holding handle at the bottom of the bag, emptying becomes easy. Bag size is determinate by weight of leaves and debris, so when full, can be easily lifted off the gutter edge, brought down and emptied.

Abstract: A mass transfer system (10) for decontaminating a liquid or gas stream that includes a container (12) with a gas inlet (14) and outlet (16), a liquid inlet (18) and outlet (20). The container is adapted to channel gas and liquid streams from inlet to outlet. At least one grid (24) is mounted within the container in the gas and liquid streams. The grid (24) has a plurality of apertures to disperse the gas flow as it passes through the grid. The dispersion of the gas flow creates a fluidized bed within the container. The grid (24) is preferably parabolic in shape. A light emitting unit (40) is positioned on the container so as to emit light into the container and irradiate at least one of the streams. Gas and liquid streams are mixed to form a turbulent zone, thereby increasing the liquid surface area. The light emitting unit (40) irradiates the turbulent zone to catalyze a chemical reaction. In one embodiment, an oxidant is added to one of the streams and is irradiated with ultraviolet light to produce hydroxyl radicals, which chemically reacts with the contaminants in the stream.

Inventor: AMER MAHER
IPC: G11C11/56
Filed: 1998-10-30
Abstract: The invention is an integrated circuit data storage array with storage cells disposed in an array of rows and columns with each cell having a number of subcells. The physical location of the subcells substantially reduces the space taken by horizontal data line used for accessing columns. This is accomplished by locating subcells of the same row number, the same bit number, and different column number adjacent to each other in the horizontal direction. As a result, a horizontal data line only extends between adjacent subcells and significantly reduces the wasted layout of multibit horizontal data lines.

Title: Side looking hall-effect vehicle speed sensor
Inventor: MIERZWINSKI EUGENE P
IPC: G01P3/488
Filed: 1999-01-21
Abstract: A speed sensor for sensing rotating speed of a wheel having projections. An elongated tubular sensor body connects to a flange, the flange being adapted from mounting in a housing wall in proximity to the wheel. A Hall-Effect sensor is provided within the sensor body and circuitry is also located there for processing signals from the Hall-Effect sensor. The Hall-Effect sensor is positioned for sensing the projections of the wheel through a portion of a peripheral sidewall of the cylindrical sensor body so that the Hall-Effect sensor is "side-looking". An alignment mark is employed to position the Hall-Effect sensor in sensing alignment with the wheel. A diameter of the flange cooperates with a placement of a receiving aperture in the housing for setting a width of a gap between the portion of the sensor body through which the Hall-Effect sensor is sensing and the projections of the wheel.

Abstract: People who decide to have long hair face occasions when the length of their hair can cause them concern. (1)Safety - Those working around machinery can become seriously injured if hair gets caught. Also, those involved in food preparation or other sanitized situations must have their hair contained. (2)Hair Damage - Many outdoor activities including motorcycling, sailing and just windy conditions themselves can leave long hair twisted, tangled and beat up. (3)Social Occasions - From business interactions to informal outings, some prefer their hair controlled or out of sight. I have a new invention - a hair enclosing device (here-in called a Hair Tube) that addresses these concerns. It can be quickly attached and enclose all or a portion of gathered long hair. It is less expensive and simpler to manufacture and use than previous hair wrap type devices. It basically consists of a highly elastic (lycra R or spandex R) tube that gathered hair is inserted into. One end of the tube is partially constricted to prevent the tube from sliding out of the hair.
