Title: Polyester backed acrylic composite molded structure
Inventor: KUSZAJ KARL T
IPC: B32B7/00
Filed: 1990-05-11
Abstract: A polymeric composite structure having a configuration of a bathtub and a process of manufacturing the structure is disclosed. The polymeric composite structure includes an acrylic shell (12) and a plastic molded backing layer (14) which is bonded to a non-finish side (21) of the acrylic shell. A fiber reinforced resin layer, preferably fiberglass, is adhered to the non-finish side of the acrylic shell. A weight bearing reinforcing structure (16), such as chip-board, is adhered to the non-finish side of the shell (21) and to the fiber reinforced layer embedded within the molded polymeric backing layer. The molded polymeric backing layer (14) is made from a cross-linked thermosetting polymer, preferably a polyester blend, which does not contain isocyonate. The backing is bonded to the non-finish side of the shell and surrounds the fiber reinforcing and weight bearing reinforcing structures (16). The fiber reinforcing layer is bonded to the shell by a silane based coupler. The backing layer also includes a curing promoter, a peroxyde cross-linking promoter and a filler such as calcium carbonate, sand or other fillers. The composite structure is manufactured by a process which includes preforming an acrylic shell, reinforcing a non-finish side of the acrylic shell with a resinous mixture of reinforcing fibers by spray-up and roll-out techniques and arranging the reinforced shell in a mold with a non-finish side covering a reinforcing structure placed below the floor of the shell. An uncured mixture of the thermosetting polymeric backing and promoter is injected into the mold coating the non-finished side of the shell and covering reinforcing fibers and chip-board structure. The thermosetting backing material is cured sufficiently to permit demolding of the composite structure without damage. The shell is preferably primed with a silane based coupler prior to the reinforcing step. In an alternative manufacturing process, the spray-up reinforcing step is replaced by the placement of a fiberous mat within the mold, surrounding the non-finish side of the shell. The fiberous material may include a fiberglass woven or a mat material or it may include a preformed fiberous structure.

Patent CA-2096416-A1 (CA)
Inventor: MCKAY CHRISTOPHER B
IPC: A63H1/16
Filed: 1991-11-12
Abstract: 2096416 9209349 PCTABS00013 A top is provided with a conical body having a soft porous parabolic point at the top's conical apex which simultaneously grips and tracks a writing surface over which the top travels. When the top is spun, the point at the apex grips the writing surface and allows the top to travel over the writing surface leaving an ink imprint in its path. During spinning, the top precesses with the rotating angular velocity characteristic of a top spinning down about a fixed point. However, the tip of the top at the conical apex does not remain fixed with respect to the writing surface; rather, the tip travels on its own course over the writing surface as a function both the angle of the tip with respect to the writing surface and the angular spin velocity of the top. As a consequence, the travel of the tip interacts with the forces of top precession to produce a group of characteristic traced spirals on the writing surface. In one embodiment of the invention, provision is made to vertically adjust the tip of the top in elevation with respect to the remaining mass of the top to adjustable vary the resultant spirals. A serendipitous result of the combination is that ink filled writing instrument in the top experiences a complete exhaustion of its contained ink supply before ceasing to write a condition not experienced by most such pens during there in service life.
Patent CA-2099172-A1 (CA)
Title: Data pipeline system and data encoding method
Inventor: WISE ADRIAN P
IPC: G06F15/00
Filed: 1993-06-25
Abstract: A pipeline structure processes data in a series of stages, each of which has a data input latch (LDIN) and passes it on to the next stage in the pipeline via a data output latch (LDOUT). The stages are preferably connected to two non-overlapping clock phases (PHO, PH1). Adjacent stages are also connected via a validation line (IN_VALID, OUT_VALID) and an acceptance line (IN_ACCEPT, OUT_ACCEPT), and in some embodiments also via an extension bit line (IN_EXTN, OUT_EXTN).      Input data is transferred from any stage to the following device on every complete period of both clock signals only if both the validation and acceptance signals in the respective latch are in an affirmative state, whereby data is transferred between stages regardless of the state of the validation and acceptance signals in other stages. A two-wire interface is thus formed between the stages. Address decoding circuitry may also be included in any of the stages so that a stage manipulates the input data stream only when one or more current data words have a predetermined bit pattern. The extension bit line conveys an extension bit that separates fields of different data blocks in the data stream. The invention also includes a method for uniquely encoding data blocks so that only intended pipeline.stages are activated, with others simply passing input data through.
