Patent CA-2149226-C (CA)
Inventor: WOODHAMS RAYMOND T
IPC: B29C48/30

Granted: 1998-12-15
Abstract: There is disclosed a process for the continuous production of a thermoplastic product having oriented components. The thermoplastic compound may include filler. Preferably the filler material is characterized by high aspect ratios (length to diameter). The filler may be an inorganic filler such as mica and talc flakes, glass and carbon short fibers or organic cellulosic materials derived from wood/forest by-products and agricultural by-products. Plastics such as polyolefins, vinyls, styrenics, polyesters and polycarbonates may be used. The process may be used to manufacture both integral foam products and substantially solid products of various shapes which may have flexural/bending strength and modulus 2-10 times higher than conventionally produced products made of the same plastic/polymer material (foamed and unfoamed). The product produced by the process may have filler concentrations as high as 75 percent. The product is made by an extrusion process which orients the thermoplastic polymer and the filler, when present, in the longitudinal direction during extrusion, and which prevents relaxation of the thermoplastic polymer thereby substantially preserving the imparted orientation. With respect to the integral foamed core embodiment, the die assembly is designed to facilitate orientation of polymer molecules and filler particles, when present, in order to produce an oriented skin; to form a cavity in the thermoplastic compound; to foam thermoplastic compound into the cavity due to the action of a foaming agent; and to cool the thermoplastic compound to form an integrally foamed product.

Abstract: A heat sensitive system comprises a document having a localized, non-pressure sensitive, coating of chromogenic composition activated at moderate temperatures.  Quickly striking the chromogenic composition with a fingernail or blunt object produces a colored image by frictional heat.  The chromogenic composition contains a chromogenic compound and a color developer which are non-pressure sensitive and non-reactive at room temperature.  The chromogenic composition can be an intimate mixture of the chromogenic compound and the developer or alternatively separate layers of each of the components.

Abstract: A compact diversity antenna is presented consisting of two electrically isolated orthogonal loop conductors joined at a midpoint. This midpoint is also electrically attached to a vertical conductor which produces a third mode of operation electrically isolated from the first modes . The two horizontal conductors and the vertical conductor may be constructed to have various relationships with a ground plane of various shapes and sizes. Some of the possible feed arrangements for each of the antennas is presented as well as matching and tuning circuits. All three antenna elements are found to have relatively weak near electric and magnetic fields on the ground plane side of the antenna where the ground plane is small in extent. This feature provides for reduced radiation into the head and neck of the cellular phone user.
