Inventor: FENN JAMES GRAHAM
IPC: B66F7/10
Filed: 1996-04-17
Abstract: A retractable lift/ramp apparatus is disclosed for moving a load between two vertically spaced surfaces. The apparatus includes a load supporting platform which is movable between a storage and operating position and one or more  lever  arms  which  are  pivotally  coupled  to  the platform.   When the platform is moved to the operating position,  each lever arm is pivotable relative to the platform about a pivot point, so that one end of each lever arm may be selectively moved along an arcuate path beneath the platform and into contact against the lower surface to raise or lower at least part of the platform.   A pivot actuator mechanism, such as a scissor jack is provided to engage both the platform and a portion of the lever arm and is extensible or retractable to rotate the lever arm about the pivot point.   Lifting is achieved by activating the pivot actuator to move one end portion of the lever arms selectively  and  progressively  along  its  arcuate  path against the lower surface.   As the end of the lever arm moves against the lower surface, its opposite portion which is hingely coupled to the platform biases the platform upwardly or permits it to fall depending on the direction of lever arm movement.

Title: Melt fracture reduction with uv additive
Inventor: CHISHOLM P SCOTT
IPC: C08L23/06
Filed: 1996-05-08
Abstract: Thermoplastic polyolefins used in "outdoor" applications are often compounded with hindered amine light stabilizers ("HALS") in order to improve their resistance to ultra violet (UV) rays. These thermoplastic compounds may also contain inorganic antiblocks (e.g. talc; silica) to reduce the blocking of films extruded from the compounds. The combined use of HALS and antiblocks is well known to be very antagonistic towards the effectiveness of many conventional processing additives. However, the extrusion of such thermoplastic polyolefin compounds, especially those based on linear low density polyethylene ("LLDPE"), has been discovered to be improved by the use of a processing additive comprising a blend of a thermoplastic acrylic polymer and a fluorocarbon polymer. In a preferred embodiment, the processing additive is a homogeneous blend of a thermoplastic styrene/methyl methacrylate polymer and a thermoplastic copolymer of vinylidene fluoride and hexafluoropropylene.          The polyolefin extrudates produced according to this invention have reduced levels of melt fracture when extruded in conventional polymer extrusion equipment.

Title: Control solutions for the resolution plane of inverse kinematics chains
Inventor: BOUCHER YVES
IPC: G06T13/40
Filed: 1997-07-29
Abstract: A method of and a system for controlling an inverse kinematics generated animation of an articulated chain is described. A resolution plane in a default orientation is computed by determining a root-effector vector extending from a root of an articulated chain to an end effector of the articulated chain and letting the resolution plane extend through the root-effector vector. A control icon representative of a position relative to the root is visually displayed. The resolution plane of an articulated chain is manipulated by manipulating the icon and re-determining the resolution plane using the root-effector vector and a root-control vector extending from the root to the icon. The animation of the articulated chain is constrained relative to the resolution plane and a solution of positions and orientations of all limbs of the articulated chain in achieving a goal is computed and displayed.
