Abstract: ABSTRACT OF THE INVENTION    A polymerization process for preparing triblock copolymers and multiblock copolymers. The process includes the polymerization of isobut-ylene below about -40°C in a reaction mixture which includes a titanium halide, a mixed solvent, and an initiator compound selected from the group consisting of cumyl ester and cumyl ether com-pounds.  In at least some instances, the compo-nents are added in a particular order, sometimes together with a moisture scavenger.  After forma-tion of the polyisobutylene, a diene is added to the mixture containing the polyisobutylene and polymerized to form the desired copolymer.  The diene portion of the copolymer may subsequently be cyclized to produce a copolymer exhibiting both thermoplastic and elastomeric properties.  If desired the block copolymers can be subsequently modified to include functional side groups, or to provide photocuring capabilities.

Granted: 1993-06-22
Abstract: ABSTRACT OF THE DISCLOSURE   A weather strip to be attached along a door opening of a vehicle body has a main portion to be brought into pressure contact with a peripheral edge of the door frame or glass when the door is closed.  An end portion of the main portion, is also simultaneously partially pressed by an end part of a door weather strip.  The end portion has a thickness gradually decreasing toward its lower end.  One section of the lower end portion, which is pressed by the end portion of the door weather strip is formed more thinly than that of the remainder and with a knife edge.  When the door is closed, the thinner section is pressed by the end part of the door weather strip.  No space is left between the vehicle body and the door weather strip and desirably sealing performance is obtained.  The remainder thicker part of the end portion serves to rigidity and prevent the knife edge section from peeling away from the door opening.

Title: Method for reducing the cloud point of materials using an ultrafiltration separation process
Inventor: LAFRENIERE LUCIE Y
IPC: C10G73/32
Filed: 1989-07-27
Granted: 1993-11-02
Abstract: ABSTRACT OF THE DISCLOSURE           A method is disclosed for reducing the cloud point of materials comprising the steps of chilling the waxy oil so as to achieve submicron crystallization followed by ultrafiltration thereby effecting separa-tion of a permeate of reduced cloud point from a retentate.  Chilling to produce submicron crystalliza-tion is to a temperature about 3°C or less above the cloud point of the material, preferably from 0.5 to 2°C above the cloud point of the material, most preferably between 1 to 2°C above the cloud point of the material.           In general, any mixture, solution or melt containing components which crystallize at different temperature can be separated by this procedure.  The method is especially useful for reducing the cloud point of waxy hydrocarbon oils.           The ultrafiltration membrane used will be one which is inert in and non-reactive with the components of the solution, mixture or melt, will not melt at the temperatures employed, which possesses an effective pore size smaller than the submicron crystals formed upon chilling and which does not have a strong chemical affinity for the crystallized component of the feed mixture, solution or melt.

Granted: 1993-07-13
Abstract: METHOD AND APPARATUS FOR OPERATING A WELL       TO REMOVE PRODUCTION LIMITING OR FLOW RESTRICTIVE MATERIAL          ABSTRACT    A method and downhole well installation for facilitating the removal of detrimental material such as sand accumulated within a well penetrating a subterranean hydrocarbon formation.  A tubing string in the well extends to a production interval open to the formation.  A production stinger is slidably disposed in the tubing string and extends downwardly from the bottom of the tubing string into the production interval.  A seal is provided between the stinger and the tubing string which permits slidable movement of the stinger but provides for a seal against fluid flow upwardly in the stinger-tubing string annulus.  A longitudinal passage extends through the stinger and opens into the tubing string above the seal.  At least one inflow opening to the longitudinal passage is provided in the stinger near the bottom thereof.  Thus, when the stinger comes to rest upon the sand or other unwanted material accumulated in the well, the inflow opening is located adjacent the surface of the unwanted material.  A pressure gradient is established through the inflow opening into the stinger passage.  Fluid such as gas from the formation flows through the inflow opening into the longitudinal passage and entrains particulate material and carries it to the stinger passage to form a fluid stream containing entrained particulate material. The fluid-particulate material mixture passes upwardly through the stinger passage and into the tubing string above the seal.

Abstract: ABSTRACT            A method for cutting multilayer printed products in a through process comprises associating single or several printed products (2) with a first knife part (3) and to move the latter together with the printed products. During the movement, the printed products and the first knife part are engaged along a provided cutting edge (4) and subsequently moved past a second knife part (5).  Through the cooperation between the first (3) and second (5) knife parts, the printed products (2) are cut along the intended cutting edge (4).            A corresponding apparatus has a plurality of conveying units for the printed products moving along a circular path.  The conveying units are preferably constructed as counterknives, whilst the associated cutting knives are fixed.            Thus, even when large quantities are conveyed and the printed products are thick, a top-quality three-sided cut is obtained.

Abstract: ABSTRACT    A multistage data compression system includes an encoder for receiving input data sequences from a data source, where the encoder comprises two or more quantizer stages, each stage having a memory for storing an established set of codewords preselected such that the sum of different combinations of codewords, one for each stage, is representative of likely to occur input data sequences.  Each codeword of each stage has a respective index associated therewith.  The encoder operates to select a codeword from at least two of the stages such that the sum of the selected codewords is a closer match to each input sequence than any other sum of codewords formed from the selected stages.  When the codewords of interest are determined, the indices of those codewords are retrieved.  These indices may then be transmitted to another location, stored in memory or otherwise processed.  The system also includes a decoder coupled to the transmission channel, memory, or other mechanism which operates on the indices.  The decoder includes a decoder memory for storing the established sets of codewords with respective indices, a retrieval device for retrieving from the decoder memory the codewords whose respective indices were transmitted, stored or otherwise processed, and a summing mechanism for adding the retrieved codewords to produce a reproduction data sequence representing an approximation of a corresponding input data sequence.

Abstract: ABSTRACT OF THE DISCLOSURE A  returned tread for use on an open portion of a stairway having a stair tread constructed of wood and a return nosing joined on at least one side edge of the stair tread so as to form an exposed shaped or mitered joint on a forward side edge portion of the assembly.  The surface of the nosing which opposes the stair tread and the side edge of the stair tread are joined along at least a part of their adjoining surfaces by  tongue and groove construction.  A single finishing nail, wood screw or other suitable fastener secures the nosing to the stair tread at a position just rearward of the exposed joint.  as a result, the stair tread and nosing will not slide relative to one another at the position of the fastener or in a region next to the fastener that includes the exposed joint as the rest of the stair tread expands and contracts in width over a range due to ambient temperature and humidity changes.   In the alternative, a suitable wood adhesive may be applied to the opposing surfaces of the nosing and stair tread in and along the exposed joint without using the fastener.  Preferably, the nosing and stair tread are secured to one another by both gluing the opposing surfaces of the nosing and tread together along the exposed joint and by fastening the nosing and tread together with a suitable fastener as previously explained.
