Patent CA-2030407-A1 (CA)
Inventor: CLEGG MICHAEL W
IPC: F01N1/08
Filed: 1990-11-21
Abstract: The subject invention is directed to a muffler formed from a plurality of stamped components.  The stamped components include at least a pair of plates formed to define an array of tubes there-in.  The tubes include a plurality of unidirectional flow tubes each of which carries a portion of the exhaust gas flowing through the muffler.  The plurality of unidirectional flow tubes communi-cate with an in-line expansion chamber defined within the muffler.  The in-line expansion chamber enables exhaust gas flowing from the unidirectional flow tubes to expand significantly thereby con-tributing to noise attenuation.  The muffler may further include at least one external shell defining a chamber which communicates with the tubes or the in-line expansion chamber.

Abstract: ABSTRACT            IMPROVED PROCESS FOR THE PRODUCTION OF THROMBIN  AND HIGH PURITY THROMIBIN PREPARATIONS THEREBY                   OBTAINED            A process for the production of a liquid thrombin preparation comprises reacting each unit of prothrombin wiwth less than 50% of the conventional thromboplastin input in the presence of calcium, contacting the resultant thrombin with a phosphate buffer, and diluting and filtering the suspension. The filtrate is then applied sequentially to an anion-exchange agarose column and a cation-exchange agarose column and the thrombin fraction is step-wise eluted from the latter column with phosphate buffered saline. Liquid thrombin preparations thereby obtained have specific activities greater than 1,600 U/mg and can be used in haemostasis.

IPC: B60N2/50
Filed: 1991-03-11
Abstract: A mechanical  seat  suspension  inside  a  housing  comprises parallel scissor arms and a support arm with a cam connected to suspension springs.  The support arm, which carries the substantial majority of the seat load, has a height adjustment means and a cam with two arcuate surfaces that define an imaginary pivot point.          The use of the cam with the imaginary pivot point permits a more compact structure.  Various embodiments of the support arm with a cam end and devices using the support arm are also disclosed.  A shock absorber attached to the outside of the scissor arms dampens the stroke of the suspension springs connected to the cam.  The ratio of the shock stroke travel to the vertical movement of the seat remains generally linear and constant, thus producing a more comfortable ride.  Also included is a height adjustment mechanism on the support arm that interlocks with the cam by a pivoting pawl and biasing spring.  The height of the seat is adjusted by the relative movement of the top portion of the housing to the lower portion.  No external levers, triggers, or other structures are necessary for seat adjustment.   The tension in the suspension springs is adjustable to compensate for the weight of the rider.          Another embodiment of the suspension includes a support assembly with two support arms that move relative to a cam that can be latched in five positions.  Compression springs connected to the support assembly and disengaging arms with a disengaging roller permit a power assisted height adjustment.

Abstract: A magnetic recording and reproduction apparatus for a data processing unit is disclosed.  The apparatus includes a plurality of magnetic heads, formed integrally by a thin-film-forming technology, and a magnetic tape.   The magnetic tape has a plurality of recording tracks corresponding to a plurality of  independent data.   The recording tracks  are arranged in parallel to a moving direction of the magnetic tape, and share the same starting position.  The plurality of magnetic heads are arranged in parallel to a width direction of the magnetic tape so as to correspond to the recording tracks in a one-to-one correspondence, and are fixed at the starting position of the recording tracks.  The magnetic tape is moved in a direction in which the starting position is away from the magnetic heads for data recording onto the magnetic tape  and  for  data reproduction  from  the  magnetic  tape.          Further, the magnetic tape is controlled to automatically move in an opposite direction to the previous direction until the starting position reaches the position of the magnetic heads in response to the end of either data recording or data reproduction.   Thus, the starting position of the recording tracks corresponds exactly to the position of the magnetic heads for the start of data recording and for the start of data reproduction.

Abstract: For packet-data switching in the ISDN D channel through a digital exchange, the need for a costly frame handler for processing OSI Layer 2 and 3 functions is to be eliminated.            To do this, in response to destination information in the SET UP message, an OSI Layer 3 control unit (SE3) establishes a connection between the two OSI Layer 2 control units (SE1, SE2) of the exchange (VST), to which the data terminals (DEE1, DEE2) are connectable. Direct packet-data transfer can then take place between the OSI Layer 2 control units without further partici-pation of the Layer 3 control unit.

Title: Facing material for wet clutch plate and methods for fabricating and applying same
Inventor: GHIDORZI ANTHONY J
IPC: F16D13/64
Filed: 1992-11-16
Abstract: (3343-034) ABSTRACT OF THE DISCLOSURE       A groove pattern for the paper-based annular friction facing (38) on an annular plate (39) of a clutch plate (41) of a wet clutch to equalize the surface temperature of the friction facing and thus increase the thermal capacity of the clutch where there is continuous slippage.  The groove pattern includes one or more continuous annular grooves (42,43,44,45) dividing the friction area into at least three annular bands (46,47,48,49,50), an inner band (46), at least one intermediate band (47,48,49), and an  outer band (50), and a plurality of cross grooves (51,52) in each band which are angled with respect to a radius of the facing.  The angled cross grooves extend at an acute angle (a,b)  (10-60 degrees) to such radius.  Slip of the friction pair of plates causes a viscous pumping action.  The cross groove angle in each band of the facing is similar so as to keep all the grooves filled with cooling oil, and the cross-section of the cross grooves vary in their dimensions as between the bands.  The angled cross grooves of this pattern also provides viscous pumping of oil through the facing.  The annular bands are formed by molding before the facing is bonded to the annular plate, but the cross grooves are preferably formed continuously through the facing in blanking operation before the facing is applied to the annular plate.  When the cross grooves are formed by blanking, the facing is preferably formed with a radially thin runner strip on its outermost periphery to rigidify the facing for ease of handling before it is applied to the annular plate.  The runner strip is removed after the facing is applied to the annular plate.

Abstract: DECLARATION D'INVENTION Dans la fabrication de métaux composites à particules de céramiques, une des étapes fondamentales à la production de métaux composites se situe dans l'incorporation des particules dans le métal, qu'un bon mouillage soit bien assuré. Deux procédés de mouillage existent le premier utilise un brasseur mécanique pour obtenir un haut taux de cisaillement, le deuxième procédé est basé sur l'ajustement de la composition du liquide à celle de la particule afin que l'angle de mouillage devienne favorable. Ces deux procédés sont reconnus mais ils ont certains inconvénients tels qu' un temps de brassage très long, une usure du brasseur mécanique, des angles morts dans le four pour ce qui est du procédé basé sur le brasseur mécanique et la fragilité des produits réactifs lesquels ont tendance à former du carbure d'aluminium dans l'utilisation du deuxième procédé. Dans la présente invention, la technologie de fabrication de métaux composites se fait par un mouvement du liquide basé sur une différence de pression de gaz laquelle crée une circulation entre les deux jambes de l'appareil. L'introduction des particules se faisant dans le réacteur à l'aide d'un gaz porteur. Un tel procédé de fabrication permet une production en continue ou en discontinue, favorisant une production homogène du composite tout éliminant les irrégularités inhérentes aux procédés discontinus.
