Patent CA-2131866-A1 (CA)
Inventor: STEGALL LANNIE L
IPC: E03F3/04
Filed: 1994-09-12
Abstract: A trench forming assembly for forming a trench of predetermined shaped is disclosed according to the present invention.  The assembly includes a pair of parallel elongate frame members for defining a support surface for supporting a trench cover.  The assembly also includes an elongate form body for shaping a hardenable trench forming composition into the predetermined shape of the trench and having opposed side surfaces with which the frame members may be engaged.  The trench forming assembly further includes at least one pair of upwardly extending legs for anchoring the frame members in a predetermined location. Each upwardly extending leg is joined at a top portion to one of the frame members and is joined at a lower portion to a corresponding leg for forming a generally U-shaped structure.  The generally U-shaped anchoring leg structure maintains engagement of the frame members with the side surfaces of the form body. Once the trench is formed, the frame members may be removed, if desired, from the top portions of the upwardly extending legs to expose a pair of grate receiving recesses.

Abstract: Abstract of the Disclosure A bearing assembly for bearing tensile and compressive axial loads. In preferred embodiments, the invention is a bearing assembly for use downhole, including a first member and a second member with coinciding central longitudinal axes, and a thrust bearing subassembly in a chamber between the first and second members defined by two shoulders of the first member and two shoulders of the second member.      The second member is free to rotate, and has at least limited freedom to translate axially, relative to the first member. The thrust bearing subassembly's overall axial length is such that the first member can translate axially relative to the second member between a first configuration in which the thrust bearing subassembly bears a tensile axial load and a second configuration in which it bears a compressive axial load. The thrust bearing subassembly includes a pair of side members and a bearing between the side members. Each side member has a flat end face and an angled end surface having a central portion farthest from (or nearest to) the flat end face and two outer portions which meet at an angle at the central portion. Each outer portion of each angled end surface faces a shoulder of the first member or the second member, and each shoulder has a profile which matches that of the outer portion facing it. Each shoulder bears against an angled end surface portion in either the first or second configuration, but is held off that angled end surface portion in the other one of the configurations.

Title: Heat-transferable ink laminate and method of manufacture thereof
Inventor: LOWTHER RONALD W
IPC: B32B38/10
Filed: 1994-11-21
Abstract: A substrate, e.g. a vinyl sign, is made with heat transferable inked colours thereon. A composite structure comprising a thin polyester film, a release coating and a heat transferable ink is used for transferring the ink onto the substrate. The coating is sandwiched between the film and the ink, and is adapted so that a) it adheres to the polyester film at room temperature and releases from the film upon heating and b) the coating adheres to the heat transferable ink sufficiently that upon heat transference of the ink to the substrate, the coating transfers with the ink. A design element of the composite structure, with a first colour thereon is placed in contact with the substrate and heated sufficiently for the ink to adhere to the substrate but not permit the coating to release from the polyester film. Any paper backing on the composite is stripped off and then a background composite, with a second colour thereon, is laid on top of the substrate and the design elements. The substrate, design elements and background element are heated to a temperature sufficient for the inks to adhere to the substrate and for he coating to release from the polyester films.
