Patent CA-2027219-A1 (CA)
IPC: B60J10/82
Filed: 1990-10-10
Abstract: A weather strip for a sliding sun roof of a motor vehicle has a base portion which is attached to the peripheral edge of the sliding sun roof, and a tubular sealing portion to be contacted with a frame portion defining a roof panel opening when the sliding sun roof is closed.  A continuous single lip extends downwardly from the tubular sealing portion. A front portion of the continuous single lip, corresponding to a front end of the sliding sun roof, has a predetermined uniform length sufficient for its top end to reach the frame portion, thereby serving as a seal lip.  Left and right side portions and a rear portion of the continuous single lip, which respectively correspond to left and right ends and a rear end of the sliding sun roof have a uniform length shorter than that of the front portion thereof, thereby serving as a drip lip. This continuous single lip is made by continuously forming a single lip having a uniform length enough for its top end to reach the frame portion of the roof panel.  The lip is provided with a linearly extending thin-walled portion at its mid-length. The drip lip is formed by tearing off a top end portion of the single lip along the thin-walled portion except for the front portion corresponding to the front end of the sliding sun roof which act as a seal lip.

Abstract: This invention provides a structure for a self-contained refrigeration unit, suitable for sealing an opening in a floor between a space of air to be cooled by the unit and a warm air space. The structure comprises a number of cover panels, trays, frames, supports, mounts and grill panels that interlock for fast assembly with few screws or other fasteners, forming an upper cooling chamber, a middle insulating substructure, and a lower compressor and condensor suspension substructure. The structure allows for instant installation by simply lowering it over an opening in the floor of a room or other space that is to be cooled.          The appropriately sized opening is sealed by a gasket around the periphery of the bottom of the insulating substructure.

Abstract: ABSTRACT                The inner needle in a guillotine type ocular cutter is ground and placed within the swaged outer needle in an interference fit, so that a radial force is exerted by said inner needle on said outer needle to better shear the ocular tissue   Further, a positive stop is effected on the drive shaft controlling the inner needle so that the distance from the end of the outer needle port to the tissue is minimized.  Alternately, the drive shaft has a dwell exerted on it.

Abstract: A facility is provided in a data network to prevent a so-called connectionless broadcast message from flooding the network as a result of each network node retransmitting such messages to its neighboring nodes even though a neighboring node may have received them from another neighbor. Specifically, a node x that receives a connectionless broadcast message retransmits the message to a neighboring node y only when node x finds that it is closer to the source of themessage than node y is including any other neighbor of node y.

Abstract: A bearing holder for bearings mounted on journals includes a lower support socket secured to a frame, and a cover part pivotally connected with the socket. The cover part is able to be locked in a shut position, folded onto the bearing positioned in the support socket. In order to provide a bearing holder of this type, which makes possible the removal and insertion of the journals without releasing the cover parts by hand, and without having to be pivoted and locked for the purpose of opening and shutting, cover parts are pivotally bearinged on two upper lateral parts of the support socket about axes which are parallel to the journal. Such cover parts include an upper, longer arm and a lower, shorter arm of a two-armed lever. The lower arm forms an actuating part, which, in the folded back, opened position of the cover part, extends into the interior of the support socket, so that by lowering the bearing, which abuts against the same and is placed on the journals, into the support socket, the bearing pivots the cover parts into shut position, in which the latter has its inner, arcuate sides in snug engagement with the bearing. Thus, the cover parts which, in this manner, are folded into their shut setting, and have their end faces abutting against each other, are provided with an automatic device locking the cover parts together.
