Patent CA-2413911-C (CA)
Inventor: MARTIN GALEN MONROE
IPC: H01R13/629
Filed: 2002-12-10
Granted: 2005-11-01
Abstract: An electrical connector is provided that includes first and second housings.  The first and second housings are matable with one another to join corresponding electrical contacts. The first and second housings are movable between initial and final positions, at which corresponding electrical contacts partially and fully mate, respectively. The electrical connector includes a lever member having cam arms that engages the first and second housings. The cam arms move the first and second housings between the initial and final positions as the lever member is rotated. The first housing has deflectable ledges that retain the cam arms in a fixed position when the electrical connector is in the initial position thereby limiting movement of the lever member. The second housing has rails that align with and deflect the deflectable ledges away from the cam arms as the first housing is moved from the initial position into the second housing.

Abstract: L'invention concerne un dispositif d'échantillonnage de l'air auto-étanche comprenant un corps renfermant un filtre ainsi qu'un appareil de ventilation, tel qu'un ventilateur, destiné à conduire l'air à travers ce filtre. Une entrée d'air et une sortie d'air communiquent avec le filtre. Une commande manuelle permet d'ouvrir simultanément l'entrée d'air et la sortie d'air et d'actionner le dispositif de ventilation en vue de conduire l'air depuis l'entrée d'air jusqu'à la sortie d'air via ledit filtre. Par exemple, le corps peut présenter une forme cylindrique, une coque cylindrique pouvant être montée rotative sur ce corps. La coque et le corps comprennent des ouvertures d'entrée d'air et des ouvertures de sortie d'air alignées lorsque la coque tourne dans un sens et désalignées lorsque la coque tourne dans un sens opposé, d'où la fermeture étanche du compartiment du filtre vis-à-vis de l'environnement extérieur. La rotation de la coque permet également de fermer un interrupteur destiné à actionner le ventilateur lorsque la coque tourne dans un sens.

Abstract: A digital stamp is described which can print out a message using a moveable inkjet printhead (30) which can be moved by a mechanical arrangement of arm (35) and pivots (33, 36). A cartridge (20) containing ink feeds the printhead (30) with monochrome or color ink via lines (52). Movement of the upper section (10) of the housing towards the lower section (12) of the housing moves the arm (35) to slide the printhead (30) across the aperture (34) in the lower section (12) while at the same time electronic signals fed to the printhead (30) print out the stored message. A spring (42) returns the printhead (30) to its inoperative position once having traversed the opening (34). The stored message may be fixed, replaceable or programmable or may be one from a fixed number of stored or updateable messages or images or can be input by an attached apparatus, for example, a CCD imager, to record an image and to print it via the printhead (30). The digital stamp can replace a rubber stamp in an office or may be used to print labels in a retail environment. An infra-red ink may also be supplied which can be used to print an encoded digital message with or on top of a visual print-out as a security measure when a printhead having the necessary number of inkjet nozzles is employed.

The outer ends of the flanges (15) are bent back at right angles to form stiffening flanges (16) along the longitudinal outer edges of the flanges (15). A bridging member (18) fits inside the casing so as to span the longitudinal gap. Tensioning screw bolts (25) pass through reinforcing plate~s (20) and the flange (15). A hexagonal nut (34) is threaded onto the end of each screw bolt. The nuts fit into the channel but are prevented from turning. The heads (35) of the bolts have a hexagonal recess to take an Allen key so that they can be tightened to clamp the coupling around the pipe ends.
