Title: Polymer composites of thermoplastic and liquid crystal polymers and a process for their preparation
Inventor: PERCEC ELENA S
IPC: C08L23/02
Filed: 1992-01-31
Abstract: ABSTRACT OF THE DISCLOSURE         Polymer composites comprising a matrix of at least one thermopolastic polymer, such as high density polyethyolene, in which at least one liquid crystal polymer, such as a thermotropic wholly aromatic polyester, is substantially uniformly dispersed at a concentration of less than about 2 wt % based on the weight of the polymer composite are prepared by a process comprising blending the thermoplastic polymer with less than about 2 wt % of the liquid crystal polymer at a temperature at which the thermoplastic polymer is molten and the liquid polymer is solid. In one embodiment, the polymer composites are prepared by first blending the thermoplastic polymer with more than about 2 wt % liquid crystal polymer at a temperature at which the thermoplastic polymer is molten and the liquid crystal polymer is solid to form a masterbatch in which the liquid crystal polymer is substantially uniformly dispersed throughout the thermoplastic polymer, and second diluting the concentration of the liquid crystal polymer in the masterbatch to less than about 2 wt % by adding more thermoplastic polymer to the masterbatch again at a temperature at which the thermoplastic polymer is molten and the liquid crystal polymer is solid.

Inventor: FORTIN MICHEL E
IPC: E04B1/74
Filed: 1992-02-27
Abstract: An insulating pulp for  insulating buildings and other type structures and wherein the pulp is formed of organic fibers having a fiber length of from about 1.0 mm  to  3  mm.   Such  pulp  is  obtained  by  a  chemi-thermomechanical  pulping  process  and  the pulp may be supplied in fluff form or compressed sheet form which is later defibrillized.    A fire retardant additive and a corrosive buffing agent is added to the pulp.   A major characteristic of such insulating pulp is that it has a density in the range of from about 0.6 to 4.0 lbs/ft3 and has an excellent thermal insulation value of about R3 to R4 per inch.    The chemi-thermomechanical wood pulp is produced from debarked trees which are primarily black spruce which have these long and strong fibers.  The pulp is  applied  by  injecting  it  through  a compressed  air conduit and at the same time an adhesive is injected in the pulp  to  form  a binding  agent.    Because of  the property of the fibers and the fiber distribution in the fluff,   the  pulp  is  also  an  excellent  acoustical insulator.

Title: Electrostatic discharge protection device for a printed circuit board
Inventor: CRONIN DAVID V
IPC: H01R12/72
Filed: 1992-02-28
Abstract: ABSTRACT OF THE INVENTION         An electrostatic discharge protection device is disclosed for use with a printed circuit board (hereafter referred to as "PCB") of the type having a major portion and a dependent integral tongue having oppositely disposed PCB surfaces with conductor pads disposed thereon.  The electrostatic discharge protection device comprises a first hinge structure and a second hinge structure mounted to corresponding PCB surfaces.  Each hinge structure has a base section securely mounted to the PCB surface, an elongated arm section pivotally connected to the base section and having an electrically conductive bar disposed along the length thereof, and means for urging the electrically conductive bar against and into electrical interconnection with the conductor pads while the PCB remains disconnected from a complementary edge connector.  The PCB's subsequent mating with the edge connector operates to pivot the arm section away from the base section so as to electrically and physically disengage the electrically conductive bar from the conductor pads.
Patent CA-2066084-A1 (CA)
Title: Twisting actuators
Inventor: CULP GORDON W
IPC: H02N2/04
Filed: 1992-04-15
Abstract: ABSTRACT OF THE DISCLOSURE   This invention is for a single lamina twisting transducer made of an electrodeformable  material.  The  twisting  transducer  has  responsivity vectors which are curved or circular in nature so that when an electric field is applied the transducer will twist,  exserting an angular force rather than a  linear force as prior art transducers do.  The twisting lamina  can  be  stacked  with  a  common  electrode  between  them. The transducers  can  be  used  in  actuators  to  provide  angular  forces  in actuators. When combined in actuator stacks with linear transducers the actuator stack can be controlled in six degrees of freedom. Thus accurate moving and positioning of objects can be accomplished by use of such an actuator stack.  Further since such an actuator stack  is  sensitive to accelerations  in  six degrees  of  freedom it can  be  used  in making an accelerometer.  Other  uses  for  twisting  actuators  are  for motors  and rotational positioning of objects.

Title: Packaging system
Inventor: GEORGE MICHAEL
IPC: B65D77/00
Filed: 1992-10-30
Abstract: A packaging system is provided for a plurality of packages which are vulnerable to damage when cut into by a sharp instrument. The packaging system includes a rectangular container enclosing all of the packages and being formed of a rectangular lid and a rectangular tray, both of which have four peripheral sides of equal height. The lid and the tray come together in a container configuration, preferably in a mating and nonoverlapping configuration, to form the container. A shrink wrap material is applied about the container and shrunk into engagement therewith so as to encircle the container in three dimensions and thus hold the lid and tray in the mating configuration. The shrink wrap material is suitably weakened to allow a manual tearing of the shrink wrap material to release the lid and hence open the container. The shrink wrap material is weakened by a longitudinal slot located adjacent the lid and extending from one side of the lid to an opposite side and two paired series of weakenings in the shrink wrap material. Each respective paired series extends laterally away from the slot and each paired series has one series of weakenings separated from the other series and provided along the lid adjacent a respective side. Preferably, the packages are rectangular and arranged in two rows in the container, and selected sides include apertures therein which together provide a view of each one of the packages.

The volatilized contaminants from the second drum are returned to the burner of the first drum for at least partial oxidation and reduction of the higher fractions to lower fractions.  The dust and gases exiting the first drum flow to a baghouse for separation into dust and volatilized contaminants.  The dust is returned to the soil.  The volatilized contaminants are further eliminated, e.g., by oxidation.
