IPC: E21D21/00
Filed: 1992-07-10
Abstract: A mine roof expansion anchor having a conventional tapered camming  plug  and  radially  expansible  shell  having  associated therewith an element which resiliently engages the wall of a bore hole as a roof bolt carrying the anchor is inserted in the hole.          The resilient element may be incorporated in the structure of a bail having bore wall engagement portions position in a plane closer to the lower end of the expansion shell than the lowest position of the tapered plug after full expansion.  The engagement portions may comprise outwardly and downwardly extending portions of the bail legs, either at the terminal ends or pierced from the bail material slightly above the ends.  In another embodiment, the engagement portions extend from a support nut positioned on the bolt below the lower end of the shell.

Inventor: SZATKOWSKI JAMES G
IPC: B61K3/02
Filed: 1993-03-09
Abstract: A lubrication applicator presses a block of solid lubricant against the flange of a locomotive wheel. An applicator nozzle loosely fits over the body of the applicator and lightly engages the block of lubricant to bridge the gap between the body and the wheel. The applicator is supported by a main bracket fixed to an unsprung portion of the locomotive truck, such as a journal box or a traction motor, and an adjustable bracket which establishes a good attitude of the applicator and is movable radially of the wheel to accommodate wheels of different diameters. A bracket attached to a journal boat fits in a restricted space between the truck frame and the wheel and comprises a plate with upper and lower channels attached to opposite sides to provide strong and light structures subject to minimal inertial loading in a severe vibrational environment. To lessen the inertial forces the brackets angle upward (rather than horizontally) to position the applicator within about 45° of the vertical plank of the wheel.

Title: Extrusion Die with Interchangeable Extrusion Nozzles
Inventor: LUPKE MANFRED A A
IPC: B29C48/11
Filed: 1992-05-11
Abstract: The annular channel elongate nozzle of an extrusion die (10) suitable for use for extrusion into a travelling mold tunnel, has an inner core (16) profiled for attachment to any one of a number of interchangeable end fitting nozzles outlet (100). The profiling takes the form of a step between an upstream portion (22) of the core and a reduced diameter downstream portion (24). Each end fitting outlet has an annular sleeve (34) to fit about the downstream core portion to extend the surface of the upstream portion of the core. The sleeve abuts the step (26) thereby locating the end fitting outlet correctly. No locking means is necessary between the end fitting and the core in the region of the nozzle. Attachment may be effected between them at a location downstream of the point at which extrudate is extruded into the mold tunnel.  Hence, attachment is not hampered by the presence of extrudate and the attachment (40, 20, 25) may not interfere with the flow of extrudate.

Patent CA-2113865-A1 (CA)
Title: Therapeutic pressure device
Inventor: CIRONE SAMUEL A
IPC: A61H1/00
Filed: 1994-01-20
Abstract: ABSTRACT OF THE DISCLOSURE A therapeutic pressure device has a handle from which a leg extends, the leg carrying a pressure foot at its end remote from the handle. The foot is mounted on one end of a longitudinally slidable rod within the leg, and the other end of the rod bears against a pressure transducer which generates an electricalsignal which is a function of the force with which the rod bears against the transducer. The generated signal is used to determine a read-out which is a function of the instantaneous force applied against the foot. In a preferred form, a first audible signal is generated when the amount of force exerted on the foot is less than a pre-set value, and a second audible signal is produced when the amount of force is equal to or greater than that pre-set value.

IPC: A01K71/00
Filed: 1994-03-10
Abstract: A fishing net is suspended from a corkline. A monofilament line is formed into three loops which are clamped together. The first of these three loops forms a knot around the corkline and the other two loops weave through the fishing net to hold it in place. The first loop is wound around the corkline in one angular direction for about one turn. It then crosses the portion of the first loop that is below the corkline. It then again passes around the corkline but in an angular direction opposite said one direction. Afterward, a limited portion of the loop that was rapped around the corkline is free. The other loops are then passed through this free limited portion and the knot is tightened.

Title: Method and assembly for loading a doctor blade
Inventor: KOSKINEN JUKKA
IPC: B05D3/00
Filed: 1994-04-11
Abstract: This invention relates to a method and assembly for loading the doctor blade of a doctoring unit used, e.g., in coating a paper web, characterized in that the blade can be loaded close to the edge of the blade without compromising the accuracy of blade profile control. The blade is loaded by means of a backing member (8) having a Z-shaped cross section in which one side of the section forms a base (13), while the middle part forms a waist (18) which turns toward the base (13), and the other side (12) of the shape forms tip (12) pointing to an opposite direction relative to the base (13) and has at its end a tapering edge suited for pressing against the doctor blade (7). This approach is capable of eliminating the sliding movement of the backing member (8) relative to the blade which tends to impair the accuracy of blade pressure control.
Patent CA-2122618-A1 (CA)
Inventor: CHANG KEN K
IPC: C08L67/06
Filed: 1993-09-01
Abstract: The present invention is based on the unexpected discovery that the low profile additives (LPA) disclosed in U.S. Pat No. 5,116,917 provide effective shrinkage control when used with various blends of vinyl ester and polyester resin systems. This LPA is unique in that its low profile efficiency is not affected by the different reactivities displayed by blends of vinyl ester resin and polyester resin at different blend ratios. This LPA is equally effective is formulations of all vinyl ester resin, all polyester resin, or any combination of such two resins. The present invention, then, is directed to a thermosettable resinous composition of between about 0 and 95 wt-% of a thermosettable vinyl ester resin; between about 5 and 100 wt-% of a thermosettable polyester resin; and between about 5 and 40 wt-% of a low profile additive comprising a non-gelling, saturated polyester formed from dibasic acid and an EO/PO block copolymer having an EO/PO molar ratio ranging from about 0.1 to 0.9, said polyester having an acid value of greater than about 10. The EO/PO polyether polyol can be built on a combination of diol, triol or other compound with active hydrogen groups, so long as the LPA product does not gel.
