Patent CA-2125650-A1 (CA)
Title: Pap Smear Collection Device
Inventor: STRICKLAND RICHARD D
IPC: A61B17/32
Filed: 1992-11-20
Abstract: A device (10) for simultaneous collection of cells from the endocervical canal and the cervical face of the uterus and methods of use. The device (10) has an elongated handle (12) having one cell-collecting member (30) projecting from the handle (12) at an axis perpendicular to the axis of the handle (12) for contacting with the cervical face of the uterus, and one cell-collecting member (20) projecting from the handle (12) along the same axis as the handle (12) for contact with the endocervical canal of the uterus. Along each member (20, 30) project sets of bristles (26, 32) which, because they are perpendicularly positioned on each member (20, 30), provide mild abrasive action to the endocervical canal and the cervical face when the device (10) is inserted into the uterus and rotated, so that cells from both regions are collected onto the bristles (26, 32).

Title: Elevator drive having a traction sheave integrated with, and smaller than the rotor
Inventor: AULANKO ESKO
IPC: H02K7/14
Filed: 1994-06-22
Abstract: The elevator machinery (26) comprises a motor (6) and its traction sheave (18). The rotor (17) is disc-shaped and air gap (ir) between it and the stator (14) forms a plane which is substantially perpendicular to the shaft (13). The stator (14) forms a ringlike sector (28) and is placed in an outer part and the traction sheave (18) is fixed to the rotor, between the stator (14) and the shaft (13). The diameter of the traction sheave is smaller than that of the rotor. The structure of the motor allows the use of traction sheaves (18) of different diameters (2*Rv) with rotors (17) of the same diameter. The motor is very flat, i.e. its length in the axial direction is small. <IMAGE>

Title: Casing drive apparatus
Inventor: FIELD RAYMOND G
IPC: E21B43/10
Filed: 1994-06-28
Abstract: There is a need for a device for driving plastic casing into a water well, or for removing such casing from the well without damaging the casing. This need is met by a casing drive apparatus which includes a shoe for attachment to the bottom end of a plastic well casing, an annular groove defining a pair of shoulders in the sleeve, a drive sub for insertion into the sleeve, a plurality of dogs pivotally mounted in the drive sub for engaging the shoulders, and helical springs for biasing the dogs outwardly into engagement with the shoulders, whereby, when the sub is slid into the sleeve and the dogs engage the shoulders, vertical force exerted on the sub results in movement of the dogs against the shoulders to effect vertical movement of the sleeve and consequently of the well casing.

Title: Lightweight handle
Inventor: HARDIGG JAMES S
IPC: A45C13/26
Filed: 1994-07-22
Abstract: Disclosed is a light weight handle assembly adapted to transport a heavy duty container which may contain sensitive electronic components. The handle assembly of the present invention generally comprises a stationary bracket which mounts to a container wall and a movable handle pivotally connected to the bracket. The bracket is formed with an inner portion that is adapted to rotatably engage with a pair of pivoting arms extending from the movable handle so that the light weight handle may easily be assembled and disassembled. The stationary bracket is also formed with two stationary stop members while each of the pivoting arms are formed with a corresponding movable stop member. The stationary stop members and movable stop members each have a substantially planar contact surface which are designed such that when the movable handle is pivoted to the lifting/operative position, the movable stop members are in contact with the stationary stop members with less stress in the materials than in conventional handles. The lower stresses enable a strong handle to be made of plastic material such as polyethylene.

Abstract: Method and apparatus wherein a disturbance acting on a tired wheel of a vehicle is estimated by a disturbance observer on the basis of the detected angular velocity of the wheel. In one form  of  the method,  the  wheel angular  velocity  is compensated for the disturbance, depending upon the amount of change  of  the wheel  angular  velocity caused  by  the disturbance.  In another  form of the method,  the  angular acceleration of the wheel as well as the disturbance  is estimated by the observer, and the moment of inertia of the wheel is obtained according to a relationship between the estimated disturbance and angular acceleration of the wheel.

Title: Method and apparatus for the classification of particulate matter
Inventor: TAPPER ULF A S
IPC: G01T3/00
Filed: 1994-12-19
Abstract: Particles are classified according to the presence or absence in the particles of a particular substance. In one example, kimberlite particles (16) are analysed for the presence of diamond (36). In the method, each particle (16) is irradiated with a beam (20) of fast neutrons at a resonant energy level for the particular substance. For each particle an image is derived which is representative of transmission of the beam by the particle. The particles are then classified according to whether or not the derived image is indicative of the presence in the particle of the particular substance. The method can be enhanced by irradiating the particles with neutron beams at resonant and non-resonant energy levels, and a resultant image is derived from the transmission spectra at both energy levels. The classification is then made from an analysis of the resultant image.
Patent CA-2139487-A1 (CA)
Inventor: IOSIFIDES MINAS
IPC: E04D13/17
Filed: 1994-05-13
Abstract: 2139487 9426998 PCTABS00034 This invention relates to the heat insulation of roofs and floors. In accordance with the invention the surface (1) is covered with a heat-insulating material (2), and supports (4) are placed on the said heat-insulating material (2). A monolithic, rigid and waterproof shell (7) is then placed, on the supports (4) so that an air-gap (3) is formed between the said heat-insulating material (2) and the said shell (7) and so that the said shell (7) may slide on the said supports (4). The ability of the finally constructed shell (7) to slide freely on the supports (4) actually protects the shell (7) from cracking due to overheating and overcooling.  Further, according to the invention, the air-gap (3) communicates with the outer-space, a feature ensuring ventilation of the air-gap (3) and consequently preventing the development of moisture on the heat-insulating material.

Filed: 1995-01-27
Abstract: An apparatus and method for improving the scoring skills of a player practicing a sport, such as hockey, ringette, broomball, soccer and lacrosse, involving propelling a playing piece into a goal tended by a goalkeeper is disclosed. A target support is sized to approximate the goal and at least two targets positioned thereon are representative of areas which are typically unprotected by a goalkeeper in a common goal guarding position. A sensor detects a player in a predeterminedarea proximate the target support and generates a signal to a processor which executes a program to indicate at least one of the targets as a current target for which the player should aim. The current target indicator is activated for a predetermined period of time, for example dependent on the skill of the player, or until the playing piece successfully strikes the current target. The processor preferably accumulates statistics useful in gaging the skill progression of the practicing player.

Filed: 1995-05-23
Abstract: La présente invention est un mécanisme de conversion du mouvement longi-tudinal et alternatif des pistons d'un moteur à combustion, en mouvement circulaire de l'arbre de transmission. Ce mécanisme est constitué d'au minimum deux jeux decages d'entraînement, chaque cage d'entraînement étant de forme rectangulaire etcomprenant deux crémaillères disposées parallèlement le long des parois internesde ladite cage et deux pistons diamétralement opposés (solidaires et aux extrémités de ladite cage). Les deux cages d'entraînement sont disposées parallèlement et se déplacent alternativement par le biais desdites crémaillères sur un pignon comprenant deux secteurs partiellement dentés et décalés d'environ 90 degrés. Ledit pignon est solidaire de l'arbre de transmission. Le mouvement linéaire et alternatif des pistons entraîne les crémaillères et ces dernières entraînent le pignon qui entraîne l'arbre toujours dans la même direction. Des butées anti-recul situées en fin de course des crémaillères empêchent leur désynchronisation lorsque le moteur est arrêté.
