Abstract: La formation d'un matériau abrasif consiste à enduire un substrat (10) d'un adhésif (11) mettant le substrat en contact avec une quantité de particules abrasives dures (12), puis à retirer toutes les particules non maintenues par l'adhésif. Les particules restantes sont entourées d'un matériau frittable ou fusible tandis que les particules sont temporairement maintenues. L'adhésif recouvrant le substrat peut être appliqué en une configuration, une couverture uniforme et à l'aide de masques (14) destinés à faire coller les particules dans certaines zones afin d'obtenir la configuration voulue. Tandis que les particules sont maintenues sur le substrat, on peut appliquer une force physique destinée à orienter uniformément les particules, ensuite on peut appliquer une poudre, ou le substrat peut être appliqué sur une préforme. Le traitement ultérieur à la chaleur et/ou à la pression achève le matériau abrasif.

Abstract: A cutting head apparatus for use in a high speed horizontal wrapper.  The apparatus has two modular cutting heads each with a cutting shaft.   The cutting shafts cooperate for cutting and sealing wrapping material between the  products  being wrapped.    The  cutting  shafts  are journaled  for  rotation  in  bearing  blocks  located  on opposing ends of the shafts.  Each modular cutting head can be mounted in at least two operative positions on a cutting head support frame.   The bearing blocks of the modular cutting heads are mounted on the cutting head apparatus to permit movement of the shafts away from the cutting area in the event a product becomes misaligned and the cutting blade and anvil contact the misaligned product.

Abstract: A system for allowing software publishers to control which video stan-dard(s) can be recovered from an optical disk (23) containing video source ma-terial. The disk may be digitally encoded so that any of NTSC, PAL and other video signal standards can be generated upon proper decoding. But the disk also includes a code which can lock out one or more standards. Players (21) for such disks may be capable of generating video signals according to all popular stan-dards, in which case the user selects a desired standard. However, the player will generate a video signal of the selected standard only if there is an appropriateauthorization code on the disk. The system allows manufacture of "universal" players without necessarily impacting the contractual and marketing plans of mo-tion picture companies, for example, which release films in different territories at different times. The control technique can be extended to lock out specific territories. Each player has a built-in territory code. The player will play a disk only if the disk contains an authorization code for the player's specific territory.

Title: Methods for reducing inhibition of nucleic acid amplification reactions
Inventor: WOODARD DANIEL L
IPC: C12Q1/68
Filed: 1996-09-12
Granted: 2000-02-08
Abstract: It has been found that certain glycoproteins, particularly mucins, are inhibitors of nucleic acid amplification reactions and that inhibition of the amplification reaction is associated with partial degradation of the carbohydrate chain. Partial degradation of the carbohydrate of a non-inhibitory glycoprotein renders it inhibitory, and partial degradation of the carbohydrate of a slightly inhibitory glycoprotein makes it more inhibitory. Sample processing prior to amplification may contribute to partial degradation of the carbohydrate chains of the glycoproteins which are present and increase their inhhibitory effect. In contrast, complete removal of the carbohydrate significantly reduces or completely eliminates the inhibitory effect. Methods for reducing or eliminating glycoprotein-associated inhibition of nucleic acid amplification reactions are also disclosed.

Abstract: A process and apparatus for the continuous solid state forming of semicrystalline polymers using roll-drawing is disclosed.  The output of an extruded thick polymer profile is stabilized by a gear pump.   The profile is passed through a die for the desired geometry and a cooling calibrator.   The profile is heat conditioned in heating tunnels to a temperature below the melting point prior to deformation between sets of rolls.  A plurality, e.g. four pairs of rolls apply both compression and tension to the polymer profile.  The tension applied on the profile, the roll  gap,  the  linear  speed  of  the  profile  and  its temperature are monitored and controlled for the amount of polymer deformation and relaxation allowed.  High tensile modulus  and  strength,  both  in  the  longitudinal  and transverse  direction  of  the  polymeric  strip,  can  be achieved.

Title: Apparatus for axially positioning the roll shell in a hydrostatically loaded controlled deflection roll
Inventor: BROWN DALE A
IPC: D21F3/08
Filed: 1995-08-10
Granted: 2001-01-30
Abstract: A controlled deflection roll (1) has a rod shell (2) which is hydrostatically radially supported by internally disposed hydrostatic shoes. In order to axially position the roll shell (2) a mechanical location link (23) is provided which is disposed externally of the roll shell (2). The link is coupled at one end to an element attached to the roll shell (2), and is coupled at an opposite end to a fixed support, such as a floor stand (7). The end of the roll at which the locating link (23) is disposed is thus axially fixed, while the opposite end of the roll remains free to float. The locating link (23) can be connected to an oscillator to oscillate the roll shell (2) axially during operation so as to distribute any non-uniformities in the roll shell (2) and thus to mitigate their effect on the sheet.

Patent CA-2212105-C (CA)
Inventor: WOOD JAMES A
IPC: B60T8/18
Filed: 1997-07-31
Granted: 2001-07-10
Abstract: A control unit includes several magnet and air piloted valves, a transducer,  a transmitter,  a pressure switch and a pipe network.   Controlled by a central controller, the apply and release valves allow a first trainline to charge a pipe network or vent to atmosphere whereas the emergency release valve can vent a second trainline to atmosphere.   The transfer valve connects the first trainline to a command port of the control unit unless its pilot port receives an emergency braking request in which case it connects the pipe network to the command port.          The transducer converts pressure in the first trainline to an electrical signal.  The transmitter conveys this signal to a control bus.  The pressure switch closes if the second trainline charges to a preset pressure.   Upon closure of the pressure switch and a command from the controller, the charging valve allows the pipe network to charge the second trainline to a threshold level.  The maintaining valve permits the pipe network to charge the second trainline unless pressure at its pilot port falls below the threshold.  The regulating valve regulates air from a primary port of the control unit for use in the pipe network.  The pipe network allows the apply valve, the first trainline and the regulating valve to supply air to the transfer valve, charging valve, maintaining valve and a master port of the control unit.  When pressure in the second trainline drops faster than a predetermined rate, the vent valve vents the second trainline to atmosphere.

Title: Duree d'inspiration durant une ventilation spontanee en pression positive continue ou un traitement en assistance respiratoire

Granted: 2007-07-31
Abstract: L'invention porte sur un appareil fournissant de manière cyclique un gaz respirable sous une pression inspiratoire donnée et une pression expiratoire plus faible, sensiblement en synchronisation avec la respiration d'un patient (16). Un générateur de flux (10) est couplé à un système de fourniture de gaz (12) afin d'alimenter en gaz respirable les voies respiratoires du patient. Une unité de commande d'un moteur (23) reçoit un signal (36) représentatif du flux respiratoire et envoie un signal de commande (24) agissant sur un moteur électrique (25) et actionnant, de ce fait, une turbine (22) afin de créer les pressions inspiratoire et expiratoire nécessaires. Cette unité de commande détecte les transitions entre inspiration et  expiration à partir du signal de flux afin de faire la distinction entre l'inspiration du patient et son expiration. Un compteur (58) mesure une première période dont le début coïncide avec le dernier passage à l'inspiration et, de la sorte, si la première période s'achève avant un passage à l'expiration, l'unité de commande (23) libère une pression d'expiration. Un autre compteur (62) mesure, de surcroît, une seconde période dont le début coïncide avec le dernier passage à l'inspiration, forçant la turbine à fournir une pression inspiratoire jusqu'à ce que se soit écoulée la seconde période même si, durant celle-ci, le patient est passé à une phase d'expiration.
