Title: Synthesis process for ziegler catalytic solids or solid components from such catalytic solids carried out inside of a multi purpose pivoting reactor, and entraining stirring rod usable in such a reactor, among other
Inventor: BRUN CLAUDE
IPC: B01D29/075
Filed: 1990-12-21
Abstract: Process for the synthesis of catalytic solids of Ziegler type or of solid transition metal components of such catalytic solids, in which a suspension of these solids or components is prepared in an inert liquid medium, and the suspension is then filtered, washed and dried to result in a pulverulent product constituting the said catalytic solid or the said component. 
<??>The operation is carried out in a single polyfunctional pivoting reactor which comprises a reaction volume (7) and a filtration volume (6), the said volumes being arranged so that the movement from one to the other is obtained by pivoting the reactor through 180 DEG . 
<??>The suspension is produced in the reaction volume when the latter is in a lower space position, while each of the operations of filtering, drying and optionally washing is carried out in the filtration volume when the latter is in a lower space position after pivoting the reactor.

Abstract: MULTI-COLORED ONE-STEP SIGN            Abstract of the Disclosure The web is a substantially flat laminate in the form of a base sheet having a permanent upper surface of plastic material  defining a base color, which may optionally be clear.  A final graphics layer covers the base sheet and has an upper surface colored differently from the base color and a lower surface adhering to the upper surface of the base.  The peel values of the upper and lower surfaces of the layer relative to each other and to the upper surface of the base are such that the cut graphic pattern in the layer remains secured to the base while the other portions of the layer may readily be peeled from the base without excessively adhering to and thereby removing the graphic pattern from the base.  Preferably, two or three differently colored layers are laminated with the base, to permit the making of a sign having two or three different colors in addition to the colored (or clear) base.  An important characteristic of the colored layers is the peel values between the upper and lower surfaces of the adjacent, laminated layers in the web, and among the upper and lower surfaces of all layers during weeding of the unwanted portions of the layers after the graphic pattern has been cut.

Title: Compatibilized blends of crystalline propylene polymers and styrenic copolymers
Inventor: MALLIKARJUN RAMESH
IPC: C08L23/10
Filed: 1991-03-08
Abstract: Thermoplastic resin compositions having good toughness and resistance to heat deformation are obtained by blending crystalline propylene polymers, elastomeric olefin polymers, random styrenic copolymers, and epoxy group-containing copolymers. For example, the composition may be a blend of polypropylene, ethylene-propylene or ethylene-propylene-diene monomer rubber, styrene/maleic anhydride copolymer, and ethylene/glycidyl methacrylate or ethylene/glycidol methacrylate/vinyl acetate copolymer. Physical properties are enhanced by the use of a two step blending procedure.

Filed: 1991-03-28
Abstract: A method of coding a set of multi-level signals that includes exhaustively comparing the set with each of a number of vectors to determine a set of difference metrics. A vector is selected that minimizes the difference metric, and a coded representation is then generated based on the selected vector. Each one of the vectors includes a geometric array of one or more elements having a respective magnitude. The metrics reflect at least two magnitudes of the elements of the geometric array. The coded representation is generated only when the differencesbetween respective pairs of magnitudes exceed corresponding threshold values. The coded representation is a null coded representation whenever the differences between respective pairs of the magnitudes do not exceed the threshold value. This technique can be used in the context of a full motion video coder based on a three-dimensional sub-band framework.

Abstract: ABSTRACT             OPTICAL SHEET INSPECTION SYSTEM      An optical inspection system inspects individual sheets  having  scrolled  and  unscrolled  edges  for defects  in  a production  line with high  transfer velocities.    Each  of  the  individual  sheets  are delivered in a production line with some spacing between them and potentially with some degree of skewness and offset from the production center line. The  inspection  system of  the  present  invention utilizes a formed viewing window over which individual sheets from the production line are delivered.   As each  sheet  is delivered over the  formed viewing window, the undersurface of each individual sheet is uniformly  and  continuously  illuminated  along  the length  of  the  formed  viewing  window  with  high intensity diffused light.  The reflected light from the  surface of  each  moving  individual  sheet  is captured by at least one video camera. As the sheet moves across the formed viewing window, a line-by-line video image is captured and stored according to a rectangularization technique which eliminates the need for customized masks.  An analyzer receives the stored information and analyzes the stored information for the presence of defects.            RCD:ds:patents\ball-12

IPC: B60R25/00
Filed: 1992-06-09
Abstract: A novel rack locking system for snowmobiles, ATV's, and other small vehicles that can be stolen by being lifted onto other vehicles. In the described embodiment the rack accommodates two such small vehicles, which are easily fastened by Pins projecting from sliding clamps; the clamps are then locked together. Thus the two vehicles and rack are virtually impossible to remove. Optionally, a permanent fastening of the rack to the ground or wall or other fixed structure adds greater security. Finally since one end of the vehicle is raised onto the rack, freezing-in of the vehicle in near-freezing usage conditions, a continuous problem in northern countries, is effectively avoided.
