Filed: 1990-08-30
Abstract: Bulky split fibers having bond strength are produced by preparing a composite synthetic resin film of three layer structure having a polypropylene layer formed of a poly-propylene/polyethylene blend and a polyethylene layer on either surface of the polypropylene layer, slitting and stretching the composite film to thereby form stretched tapes, and causing splitting of the stretched tapes for fibrillation. An integral article is prepared from the resultant split fibers by mixing them alone or with plant fibers and then heating at a temperature between the melting points of polyethylene and polypropylene, thereby integrating together the split fibers with each other or with the plant fibers.

Title: Turbulent fluid bed paraffin conversion process
Inventor: AVIDAN AMOS A
IPC: C10G35/14
Filed: 1990-02-12
Abstract: A fluid-bed catalytic paraffin upgrading process is disclosed. By closely controlling catalyst particle size distribution and density, together with feedstock superficial vapor velocity, the fluid bed is maintained in a turbulent flow regime. Surprisingly, maintaining the fluid bed in a turbulent flow regime shifts the product selectivity away from methane and ethane and toward the more valuable products hydrogen, light olefins and C5+ gasoline. In the most preferred embodiment, the catalyst contains a dehydrogenation metal component such as gallium, zinc, platinum or rhenium to provide a C5+ gasoline product rich in aromatics. Catalysts useful in the inventive process include zeolites as well as layered siliceous materials.

Title: Transmitter location searching system
Inventor: HUANG CHIA-CHI
IPC: G01S5/06
Filed: 1991-05-09
Abstract: RD-17,822 TRANSMITTER LOCATION SEARCHING SYSTEM                 ABSTRACT OF THE DISCLOSURE     A transmitter location searching system produces fast, stable and accurate  results  in a multipath transmission environment by geometrically partitioning the monitored area into a plurality of cells and finding the optima of a total cost function at the centers of the cells.   The original three-dimensional optimization problem is thus reduced to a one-dimensional problem.  Based on this calculation, the cell providing the smallest cost is chosen as a new candidate cell which is divided into smaller cells and the minimum costs are calculated for each of these smaller cells.   The cell that provides the smallest cost is chosen as the center of another new  candidate  cell.    The  process  is  iterated  until  a dimension  of  a  new  candidate  cell  is  smaller  than  a predetermined threshold.  By reducing the dimensions of each cell by a factor of two at each iteration,  the algorithm converges rapidly.

Title: Training vehicle skid simulating mechanism
Inventor: SARUWATARI MINORU
IPC: G09B9/042
Filed: 1991-12-31
Abstract: An automotive training vehicle capable of providing controlled simulated skid conditions selectable in either right or left directions by a driving instructor accompanying a student driver. The vehicle has conventional front wheel steer and a pair of rear wheels mounted for simultaneous turn about parallel, substantially vertical axes. A switch which is located in a position accessible to the driving instructor activates a control system to energize a drive cylinder connected to the rear wheels for effecting turn of the rear wheels from a straight ahead position through an infinite number of positions to a maximum steer position in either direction from the straight ahead. The control system when in a non-activated condition places the drive cylinder in a hold position preventing turn of the rear wheels from the selected position. The severity of the simulated skid and its timing are thus fully within the control of the driving instructor.

Title: Apparatus for spreading granular and liquid materials
IPC: E01C19/20
Filed: 1992-01-31
Abstract: Apparatus for Spreading Granular and Liquid Materials James J. Wise John A. Doherty ABSTRACT OF THE DISCLOSURE           A granular and liquid material spreading system mounted on a vehicle.  Granular material is moved  from  a  hopper  to  a  delivery  means  using hydraulic pumps and motors.  The hydraulic system also drives a liquid delivery system.  A control system is provided to control the amount of granular material and liquid material applied to a surface.  The feed rate of liquid delivery is dependent upon the feed rate of the granular material.  The liquid feed rate may be changed within a predetermined range.   The level of liquid may be sensed to disengage the liquid delivery  system.    Initiation  of  liquid  delivery reduces  the feed rate  of  granular material  by  a variably selected percentage.

Patent CA-2067100-A1 (CA)
Title: Extending dynamic range of stored image database
Inventor: MADDEN THOMAS ETHAN
IPC: G06T5/00
Filed: 1991-09-11
Abstract: The dynamic range of a digitized image database is extended to permit shifting of encoded pixel values without 'clipping', and to provide a limited window of values into which specular highlights may be encoded and stored. Digital codes into which an image scanner output has been mapped by a scene balance mechanism are converted into a set of reduced-range digital codes of the same resolution but having a smaller range of image content values than the dynamic range of the digitized image data base. The code conversion mechanism operates to convert a maximum value of 100 % white reflectance to an encoded value that is less than the upper limit of the dynamic range of the database to allow for the placement of specular highlights that are beyond the 100 % white reflectance maximum and to accommodate shifts in the digitized imagery data at both the high and low ends of the range.
Patent CA-2070379-A1 (CA)
Inventor: KANEKO KAZUNOBU

Filed: 1991-10-09
Abstract: This invention relates to an injector supplied with medicine in which a predetermined amount of medicine (5) is sealed in a cylinder tube (1), and more particularly to an injector supplied with medicine used when it is necessary to further add a liquid when applying an injection. It is characterized in that the length of a plunger (4) is longer than the distance of movement of the plunger for drawing the liquid into the cylinder tube (1). With this construction, the inner wall portion of the cylinder tube (1) which is in contact with the medicine and the liquid when drawing the liquid is beforehand shut off by the plunger (4) and is kept in a sterilized condition, and therefore the contamination of the medicine and the liquid by bacilli or the like can be prevented.
