Patent CA-2135015-A1 (CA)
Inventor: LOEWE GERHARD
IPC: E05D11/10
Filed: 1994-11-03
Abstract: A hinge arm adapted to be attached to a vehicular seat back is pivotally connected to a bracket adapted to be attached to the seat cushion and normally is held in a fixed position by virtue of a pivoted latch on the arm engaging a fixed latch plate on the bracket.  The latch and the latch plate are formed with engageable latching faces which cause a heel on the latch to wedge into a pocket in the latch plate and prevent chucking of the seat back.  The latching faces are curved on different radii and about different centers in order to maintain tight engagement between the two latching faces and to keep the heel wedged into the pocket as the latching faces wear.

Patent CA-2167752-A1 (CA)
Inventor: MCMILLAN DONALD MARK
IPC: E04F21/00
Filed: 1996-01-22
Abstract: The mechanism consists of a crankshaft and connecting rods driving two rods which extend through the full length of the cylinder of the taper.  The rods reciprocate 180° out of phase with each other and pass through a piston assembly.  Clutch mechanisms in the piston assembly engage when the rods are moving toward the head assembly and do not  engage  for the  opposite motion.  As  a result  the piston  assembly  advances  toward  the  head  assembly  an increment of motion each time one of the rods moves in that  direction.   A  mechanism  in  the  piston  assembly engages  the  head  end  of  the  cylinder  as  the  piston assembly approaches the head end and prevents the clutches from engaging so that the piston assembly does not jam against the head end of the cylinder.  Also, mechanism is provided  to  disengage  both  clutches  and  keep  them disengaged so that the piston assembly is free to move as the cylinder  is being filled.   This mechanism involves rotating the rods to drive cams which engage the clutches to hold them disengaged.  An alternate driving mechanism between the crankshaft and the oscillating rods enables adjustment of the amount of motion of the rods for turn of the crankshaft.

Title: Device for cleaning paint brushes or the like
Inventor: HAKKER JOHANNES CORNELIS
IPC: B44D3/00
Filed: 1994-07-22
Abstract: A device for cleaning paint brushes or the like comprises a container (1) for a cleaning fluid and a plurality of wiping elements (2) projecting upwardly substantially from the bottom of the container. Each wiping element of at least a part of the wiping elements has one or more scraping edges along at least a part of its length, said scraping edges being adapted to cooperate with the paint brush to be cleaned. This is for example obtained in that each wiping element has a polygonal, preferably rectangular cross section at its end adjacent the bottom and tapers from the bottom. Thereby these wiping elements have sharp edges operating as scraping edges when the paint brush to be cleaned is moved along the wiping elements, so that an excellent cleaning action is obtained. The device can be part of an assembly which further comprises a refuse container and a cover for closing the refuse container. This refuse container with corresponding cover can be used for removing the used cleaning fluid with paint rests and can be offered closed as chemical waste to the cleansing service.

IPC: A61B8/08
Filed: 1996-07-17
Abstract: Disclosed herein is a system for positioning an ultrasonic transducer where the user can see the positioning device and a display of the image being generated at the same time. This system solves the problem of the user having to look away from the transducer to see the image. The method comprises positioning a display screen to show the ultrasonic image being generated to the user such that the user can see the positioning of the transducer and the image on the display screen at the same time. To accomplish this the display screen can be incorporated into or mounted directly mounted onto the transducer housing. Once the user properly positions the transducer and is satisfied with the image, a image capture signal can be sent by the user. Once the image is captured it can be sent to an associated computer for analysis, printed or saved for archiving, etc.
