Abstract: L'invention concerne un procédé et un appareil pour décoder une image en pixels représentant un symbole de code à barres. On balaye un symbole de code à barres suivant une première ligne de balayage pour déterminer un premier jeu de valeurs de caractère candidates, chaque valeur de caractère candidate de ce premier jeu ayant une première valeur d'erreur associée. Lorsque le balayage suivant la première ligne de balayage ne réussit pas la lecture du symbole de code à barres, alors le symbole de code à barres est balayé suivant une seconde ligne de balayage différente pour déterminer un second jeu de valeurs de caractère candidates, chaque valeur de caractère candidate de ce second jeu ayant une valeur d'erreur associée. On compare ensuite les valeurs d'erreur correspondantes associées avec le premier et le second jeux de valeurs de caractère candidates. Pour chaque paire de valeurs de caractère candidates correspondantes du premier et du second jeux, on choisit la valeur des caractères candidate ayant la valeur d'erreur associée la plus petite. Un troisième jeu de valeurs de caractère candidates est formé conformément aux valeurs de caractère candidates sélectionnées et le symbole de code à barres est décodé conformément au troisième jeu de valeurs de caractère candidates.

Abstract: A plate holding drill guide or "trocar" is disclosed including a member having a channel with an internal diameter.  A cannulated holding member having prongs is disposed, at least in part, within the channel.  A cannula extends through the prongs.          At one end, the prongs are flanged outward.  The flanged portion has an external diameter which is greater than the internal diameter of the channel.  The sliding member is displaceable over the flanged portion of the prongs.  When an annular frame of a bone plate is disposed between the prongs and the sliding member is moved toward the flanged portion, the prongs grip the frame.          A drill may be guided between the prongs through the cannula.    A method is disclosed for holding a bone plate.  An annular frame of the bone plate is positioned between prongs and aligned with a cannula extending between the prongs.  A member is displaced along the prongs.  The prongs are deflected inward, gripping the frame.

Abstract: A key generation system is implemented as follows. In an enrolment apparatus, a unique number for use with PIN operated machines or public key cryptography system is generated by manipulation of fingerprint information of a subscriber. A filter is then generated which is a function both of the Fourier transform of the subscriber's fingerprint(s) and of the unique number. This filter is stored on a subscriber card. When the subscriber wishes to generate his key, he inputs his card to a card reader of an apparatus and places his finger(s) on a fingerprint input. The apparatus generates an optical Fourier transform from the fingerprint input. The Fourier transform signal is incident on to a spatial light modulator programmed with the filter information from the card. An inverse transform is generated from the filtered signal and this is used to regenerate the key that will be used as the PIN in a PIN operated device, or as the private key in a public key cryptography system.

Abstract: The transmission of the present invention includes a multi-speed geartrain comprised of an input shaft, a mainshaft, and a plurality of constant-mesh gearsets arranged for selectively coupling the mainshaft to the input shaft for driven rotation at various speed ratios. The mainshaft can be selectively coupled to the power transfer arrangement for establishing two alternative power transmission routes. In particular, the range shift mechanism is provided for establishing a high-range power transmission route and a low-range power transmission route from the mainshaft to a quill shaft which, in turn, drives the interaxle differential.  The torque delivered by the quill shaft is split by the interaxle differential between the front and rear drivelines to establish the full-time four-wheel high-range and low-range drive modes. Optionally, the torque transfer apparatus can be provided for controlling speed differentiation across the interaxle differential or in place of the interaxle differential for on-demand four-wheel drive operation. The torque transfer apparatus can be a speed-sensitive device or an electronically-controlled transfer clutch.

Title: Cold dense slurrying process for extracting bitumen from oil sand
Inventor: SURY KEN
IPC: C10G1/04
Filed: 1997-10-02
Granted: 2001-08-07
Abstract: Average grade oil sand is mixed with water to produce a low temperature (preferably 20 - 35°C), dense (1.4 -1.65 g/cc) slurry. The slurry is pumped through a pipeline for sufficient time to condition it. Air is injected into the slurry after the last pump. The slurry density is adjusted to about 1.5 g/cc by adding flood water near the end of the pipeline. The slurry is introduced into a primary separation vessel (PSV), excess air is vented from the slurry as it is introduced into the PSV and a hot water underwash is used to heat the froth produced. Slurry loading to the PSV is greater than about 4.78 tonnes of oil sand/hour/square meter to reduce velocity gradient in the fluid in the vessel. Bitumen froth is recovered. When fed low grade oil sand, the process is modified by adding flotation aid chemicals to the slurry in the pipeline and subjecting the PSV tailings and middlings to secondary recovery with agitation and aeration in a secondary separation vessel.

Abstract: A line marking device (10) includes an elongated body (15) which mounts a marking filament (20) that is loaded with marking powder (55). When the filament (20) is snapped against a surface, a portion of the powder (55) is deposited on that surface along a well defined line. The body (15) also mounts a protractor (30) and spirit levels (22, 23) that are used to locate or set the device (10) in a predetermined position prior to snapping the marking filament (20) against the surface to be marked. 'The marking filament (20) extends through a shuttle chamber (53) that contains a supply of marking powder (55). That shuttle (50) is moved back and forth on the body (15) to recharge the marking filament (20) with the marking powder (55). In a second embodiment of this invention the marking filament (20) is pressed rather than snapped against the surface to be marked.
