Abstract: A portable cordless inspection light assembly including a lamp capable of producing a spectral distribution, which is substantially identical to daylight, color temperature. The lamp has a reflector portion around its bulb and a light outlet lens across its large end. The light includes a housing having a generally tubular housing portion. The lamp is mounted within an opening in that housing portion adjacent one end with its large end across the opening and its reflector portion extending along the opening toward the opposite end of the housing portion. Passageway portions of the through opening are provided around the large end of the lamp, and a fan assembly within the opening can propel air through the opening over the outer surface of the lamp and through those passageway portions to cool the lamp. The housing includes a manually engageable handle portion, and supports a rechargeable battery by which the bulb and fan assembly can be activated.

Abstract: A polymerization loop reactor including a loop reaction zone, a continuous takeoff, and a fluid slurry disposed in the reaction zone. A generally cylindrical wall defines the loop reaction zone. The length of the loop reaction zone and the nominal outside diameter of the generally cylindrical wall define a length/diameter ratio greater than 250. The reactor can be charged with a fluid slurry including an olefin monomer reactant, solid olefin polymer particles, and a liquid diluent. The concentration of the solid olefin polymer particles in the slurry can be greater than 40 weight percent based on the weight of polymer particles and the weight of liquid diluent. Also disclosed is a polymerization process carried out by polymerizing, in the loop reaction zone of a reactor as defined above, at least one olefin monomer in a liquid diluent to produce a fluid slurry as defined above.

Abstract: A computer pointing device comprises a mouse shell (56) having a camera (88) and mouse buttons (70, 72), at the end of a second pantograph arm (40), attached to a first pantograph arm (18), in turn attached to a base clamp (10). In a first embodiment, the angle of the first pantograph arm (18) with the base clamp (10), the angle of the second pantograph arm (40) with the first pantograph arm (40), the angle of the mouse shell (56) with the second pantograph arm (40), and the lengths of each of the pantograph arms (18, 40) are all used by a logic processor (80) to calculate the position of the mouse shell (56) in Cartesian co-ordinates for communication to a host computer.

Abstract: Polymer solids are maintained in an intermediate pressure zone for a desired polymer solids residence time and then transferred to a purge zone or other lower pressure zone. An increase in the polymer solids residence time in the intermediate pressure zone allows more diluent to flash or separate, thereby avoiding or reducing the need for a low pressure flash zone. A fluff chamber may be disposed between the intermediate pressure zone and a lower pressure zone. A transporter tank may be used to transport polymer solids after the intermediate pressure zones.

Abstract: A task light assembly including a long flexible fiber optic element capable of transmitting light between light inlet and light outlet ends; a light source at the light inlet end of the fiber optic element; and a reel assembly for supporting the light source and the light inlet end of the fiber optic element and for allowing movement of the fiber optic element between a storage position with the light outlet end of the fiber optic element supported in a storage position, and an extended use position with the light outlet end of the fiber optic element at a work location remote from the storage position.

Abstract: The present invention provides a method of finishing a wood surface for exterior exposure of the wood using a finishing film material in the form of a sheet. The finishing film comprises a flexible polymeric sheet material having a first major surface and a second major surface and a pressure sensitive adhesive layer covering at least a portion of the first major surface of the sheet material. The finishing film is adhered to the surface to the wood surface by the adhesive layer. The method of the present invention is particularly suitable for the finishing of brightwork on boats, for example, teak or mahogany brightwork. The method of the present invention is particularly suitable for finishing curved and/or compound curved surfaces due to the flexibility and elongation of the finishing film.

Abstract: A Single Well Predictive Model (SWPM) software based computer system stores a Single Well Predictive Model (SWPM) software therein. When the SWPM software is executed, the SWPM computer system will: (1) automatically produce a first specific workflow comprised of a first plurality of software modules in response to a first set of user objectives and automatically execute the first specific workflow in response to a first set of input data to produce a first desired product, and (2) automatically produce a second specific workflow comprised of a second plurality of software modules in response to a second set of user objectives and automatically execute the second specific workflow in response to a second set of input data to produce a second desired product.

Abstract: A technique is provided for insulating a winding or coil for an electrical machine such as a motor. The coil is wound and placed in a taping station. Multiple layers of insulating tape are applied along an end region with leads bent back from the end region. The taping station permits the leads to be then placed over the insulated end region, and the main body region of the coil is similarly taped in a continuous uninterrupted manner. The tape wrap pitch may be varied along certain regions, where increased dielectric strength is desired. Following the insulating tape application, an armor tape may be applied over both the end region and the main region of the coil in a continuous uninterrupted manner. The coil can then be finished and assembled in a machine such as an electric motor stator.

Abstract: The invention relates to process and apparatus for creating shaped objects from incipiently gelling alginate or low-methoxy pectate sol in which the incipiently gelling sol is guided into cavities of a movable belt. V-shaped wiper blades can be used as guides. The sol is preferably fed onto the belt at a rate not greater than the volumetric feed rate of the cavities. The process and apparatus can be used to prepare such products as imitation fruit e.g. by incorporating pureed fruit in the incipiently gelling sol.

Abstract: A pipe-bending apparatus comprises an elongate structure having a longitudinal work surface at, or adjacent to, opposite ends of which clamping means and a former are respectively mounted. The former is held fast on the work surface, and the clamping means is power-driven towards and away from it by a double-acting hydraulic ram. A series of formers are provided, each having, in plan, a semi-circular anvil mountable to face the clamping means. The anvils are each of concave vertical cross-section and of different radius from one another, with peripheral walls to locate a pipe in position in the anvil during a bending operation. The ram is supplied from a tank containing a hydraulic fluid tank which--together with the necessary hydraulic pump and electric motor--is mounted beneath the work surface.
