Patent CA-2194789-A1 (CA)
Inventor: STEVENS DALE R
IPC: B61L15/00
Filed: 1997-01-09
Abstract: A method of serialization including providing a parameter which varies along the length of the train and transmitting a synchronization signal along the length of the train to the local nodes at each car. The parameter is measured at each node with respect to the occurrence of the synchronization signal at the node.  Serialization of the cars is then performed as a function of the measured parameters.  One method is to provide the parameters by transmitting a serial signal which propagates through the train at a slower rate  than  the  synchronization  signal  and  then measuring the difference in time between the receipt of the synchronization and the serial signal at each node.  A second method of implementation is to create a pressure gradient in the brake pipe along the length of the train.  The brake pipe pressure or flow rate is read at each node upon receipt of the synchronization signal.  As a third alternative, an electric load is provided at each node in parallel to a trainline running through the train.  The current or voltage of the trainline at each node is then measured upon receipt of the synchronization signal.

Patent CA-2211415-A1 (CA)
Title: Oscillator screen cleaning apparatus
Inventor: CORD ALBERT B
IPC: B41F35/00
Filed: 1996-02-06
Abstract: An oscillator screen cleaning apparatus (10, 110) includes a housing (12, 112) having a plurality of spray nozzles (18, 118) to spray a printing screen (16, 116) with solvent. An oscillating mechanism (25, 128) oscillates the screen in front of the spray nozzles, which nozzles (18, 118) are arranged in opposing grid patterns for complete coverage of the screen with sprayed solvent. The srprayed solvent is collected, filtered and resprayed onto the screen at a high spray rate. Housing (12, 112) is coupled to a vapor recovery system (110, 145) to keep solvent vapors from escaping into the environment. In one embodiment (110), guide brackets (170) guide the screen (16, 116) perpendicular to the nozzles (18, 118) from the screen's sides to handle screens of different heights. A reservoir (120) with a sloped wall (140) and a pump (123) recaptures sprayed solvent and pumps it to the nozzles (18, 118) for recycling. A wipe down booth (152) captures excess solvent from a screen (16, 116) removed from the housing (12, 112) and directs the captured solvent to the reservoir (120).

Title: Mini deflecteur d'air pour oreilles
Inventor: DUFRESNE PIERRE
IPC: A61F11/14
Filed: 1997-10-22
Abstract: Lorsqu'une personne se promène a pied ou a vélo et que l'air ambient arrive de face ou de coté, il se produit une turbulance dans l'orifice de l'oreille. Ce tte turbulance provoque un bourdonnement désagréable percus par le promeneur, ce siflement cause une diminution de la perception des sons ambiants. Cette turbula nce peut causer des maux de têtes ou d'oreilles après un certain temps, ce qui peut rendre une activité désagréable. Les appareilles qui existent présentement pour la protection des oreilles ne sont pas adaptés pour ce genre d'activité. Ils sont volumineux, ils englobent totalement l'oreille et sont beaucoup apparent. Ils ont la forme d'une grosse co quille. La présente invention concerne un mini déflecteur d'air pour oreilles s'adaptant aux montures de lunettes. Le mini déflecteur empêche l'air en mouveme nt de produire un bourdonnement désagréable au niveau de l'oreille. Le mini déflecteur d'air n'englobe que partiellement l'oreille laissant celle-ci a l'air libre. Le mini déflecteur d'air est ultra-léger, très peu volumineux et beaucoup plus discret, surtout s'il est transparent. La forme et la position du mini déflecteur pour oreille permet d'amplifier les sons provenant de l'arrière de la tête. Le port du déflecteur permet de mieux percevoir l'arriver d'une voiture provenant de l'arriere de la tête par exemple.
Patent CA-2219500-A1 (CA)
Title: Locking armrest support assembly
Inventor: TAYLOR PHILIP A
IPC: B60N2/75
Filed: 1997-10-28
Abstract: The apparatus provides a locking mechanism for an armrest of an automobile or similar motor vehicle to a structural pin or post. The mechanism includes a cap with a lateral slit into which a button and spring are assembled. The spring outwardly biases the button which is limited in its outward travel by a detent arrangement which maintains the outer portion of the button flush with the cap. In this arrangement, the spring further engages a circumferential slot on the structural pin or post thereby locking the armrest to the structural pin or post. However, in order to remove the armrest from the structural pin or post, the user pushes thebutton inwardly, thereby compressing the spring and moving the spring out of thecircumferential notch thereby unlocking the armrest from the structural pin or post and allowing the free removal thereof.

Title: A method and apparatus for applying a printed label to a metal container and the labeled container produced thereby
Inventor: FOURNIER GILLES
IPC: B65D35/00
Filed: 1997-12-01
Abstract: A method and apparatus for labeling a metallic container, such as an aluminum collapsible tube (empty and open-ended for filling by the purchaser) with a flexible label, which is especially suited to short production runs and in such a manner that the label is bonded to the container such that it is  able  to withstand physical  abuse without peeling or breaking  away  from the  container.    Both  the  label  and unlabeled container may be manufactured in advance and stored until needed.  The container comprises an enamel coating which is bonded to  the  surface of  the  container,  the  coating comprising  an  adhesive  which  is  activated  within  a predetermined temperature range, and the label comprises a transparent film having reverse printing on the lower surface thereof.  The enamel coating is heated to a temperature within the activating temperature range to cause the adhesive to activate.  The lower surface of the label is contacted to the heated enamel coating under sufficient pressure to cause the label to bond thereto.  The temperature of the container and label is then reduced below the activation temperature range.

Filed: 1998-01-22
Abstract: The invention aims at recognition of a handwritten input character on-line with quite high accuracy.  The method of on-line  handwritten  input  character  recognition  of  the invention is characterized in that ordinary strokes and transition strokes and/or s-e strokes of a handwritten input character sampled on-line are compared with ordinary strokes and transition strokes and/or s-e strokes of dictionary's characters previously registered in a dictionary and the character corresponding to the handwritten input character is recognized on the basis of the result of the comparison. Otherwise, when the dictionary's character most similar to the input character corresponds  to a preset  character,  the handwritten  input  character  is  identified  by  using characteristic features of the corresponding character.  Thus, by comparing ordinary strokes and transition strokes and/or s-e strokes of a handwritten input character sampled on-line with ordinary strokes and transition strokes and/or s-e strokes of  dictionary's  characters  previously  registered  in  a dictionary and recognizing the character corresponding to the handwritten input character on the basis of the result of the comparison, a handwritten input character which was difficult to recognize only by means of ordinary strokes can be recognized with high accuracy.

Abstract: A method for sweeping a charged particle beam out of an isochronous cyclotron (1) comprising a solenoid forming a magnetic circuit that includes at least a number of sectors (3, 3') known as 'ridges' where the air-gap is reduced, and separated by sector-shaped spaces (4) known as 'valleys' where the air-gap is larger. According to the sweeping method, the particle beam is swept without using a sweeping device as the magnetic field has a special arrangement produced by designing the solenoid air-gap at the ridges (3, 3') of the isochronous cyclotron in such a way that the aspect ratio between the solenoid air-gap at the ridges in the region of the maximum radius, and the radius gain per turn of the particles accelerated by the cyclotron at said radius is less than 20.
