Abstract: A vehicle crash barrier (10) for decelerating a vehicle that has left a roadway includes an elongated frame having a number of sections (14, 16, 18) including a front section (14) and at least one additional section (16, 18) arranged end to end along an axial direction. The frame is configured to collapse when axially struck on the front section (14) by a vehicle. A wire cable (122) extends generally parallel to the frame and has a forward end portion anchored independently of the frame and a rearward end portion. Friction brakes (140) are mounted to the front section for engaging the wire cable (122) to generate a retarding force to decelerate a vehicle as the brake (140) moves along the wire cable (122) during collapse of the frame following impact of the vehicle against the front section (14). Each section includes a pair of side panels (42), and axially adjacent side panels are connected by a flexible tension strap (46) by fasteners (44). The tension strap (46) operates to peel the fasteners (44) out of the side panels during axial collapse. The front section (14) is releasably secured to a ground anchor (80) by a directionally sensitive breakaway assembly. (100) .
Patent CA-2009262-A1 (CA)
Inventor: BUNGE DAVID J
IPC: C08L83/04
Filed: 1990-02-05
Abstract: Aqueous emulsions of curable silicone compositions provide cured coatings having improved gloss and/or water-repellancy and/or adhesive release if formulated to contain polyvinylalcohol having a degree of hydrolysis of 90 mol% or more. The extent of improvement is directly related to the degree of hydrolysis of the PVA. PVA having an average degree of hydrolysis of from 94 to 99 mol% is particularly effective for improving these properties of cured coatings.    Conveniently, a mixture of two or more commercially available PVAs having different degrees of hydrolysis can be used to arrive at a PVA having a desired degree of hydrolysis.

Title: Compressed prefix matching database searching
Inventor: WILKINSON HUGH M III
IPC: G06F17/30
Filed: 1990-06-25
Abstract: Abstract of the Disclosure Aspects of the invention include a method of conducting a reduced length search along a search path.  A node which would otherwise occur between a previous and a following node in the search path is eliminated, and information is stored as to whether, had said eliminated node been present, the search would have proceeded to the following node.  During the search, a search argument is compared with the stored information, and the search effectively progresses from the previous node directly to the following node if the comparison is positive.  In preferred embodiments, some nodes provide result values for the search, and a node is eliminated only if its presence would not affect the result value for the search.  In another aspect, the invention features a method of conducting a two mode search of reduced length.  For a first mode of the search, nodes along a search path are provided, at least some of the nodes including one or more pointers pointing to other nodes.  A search argument comprising a series of search segments is provided, some values of segments of the argument corresponding to nodes along the search path, some other values of the segments relating to a second mode of the search.  Indicators associated with nodes are provided, each indicator indicating the segments corresponding to the second mode.  The search path is searched by processing successive search segments by inspecting the indicator associated with each node, and proceeding to the second search mode is the indicator indicates that the segment relates to the second mode.

IPC: C08L51/00
Filed: 1990-02-08
Abstract: Method for production of a thermostable crosslinked halogen-containing polymer.  Epoxygroups are added by way of a monomer as for example glycidylmethacrylate.  The crosslinking of the polymer is carried out through an organic silane which can be hydrolyzed.  By this method the crosslinking can be separated from the processing of the polymer as it is catal-yzed by moisture after the processing is carried out.  The crosslinking reaction is carried out very fast.  Good thermo-stability is gained even if the halogen-containing monomer is vinyl chloride.
