Title: Method of forming strip products from thermoplastic materials
Inventor: MALM DOUGLAS N
IPC: B29C48/35
Filed: 1995-02-27
Granted: 1999-09-21
Abstract: A method of forming an elongated trim strip product includes extruding a first strip of thermoplastic material from a die having an outlet with an area at least substantially as great as the desired cross-sectional area of the strip product in planes perpendicular to the direction of extrusion. Immediately subsequent to the step of extruding and while the extruded strip is still in a plastic state, it is passed longitudinally between cooperating forming rolls to shape the cross section of the extruded strip to the desired shape and cross section of the strip product. Further, while passing between the rolls a logo or lettering is formed on the strip. While the extruded strip is passing between the cooperating forming rolls, a backing strip of foil or thin metal is directed between the rolls in alignment with the extruded strip to bond the backing strip to the extruded strip. In a second embodiment, one or more cables of high strength flexible material, such as metal wire, are joined to or embedded in the extruded strip during the extrusion process to function as a pulling mechanism for moving the extruded strip through a cooling bath without stretching or deforming the extruded strip. After cooling, the cables can be severed from the strip if desired.

Abstract: Two or more sand additive particles are made to adhere to each other, using a binder. The finished product consists of free-flowing particles that are composed of the additive particles bound together by the binder. These bound additive particles may then be applied to sand, such as foundry sands, where, otherwise, multiple additions of additive might need to be made. The pH of the single additive particles can be controlled and separation of the additives due to different specific gravities can be avoided. Various mixtures of different additives are disclosed Methods of controlling particle size of additive particles, tendency to generate dust, degrade tensile strength or control thermal expansion of foundry cores or molds by using bound additive particles are also disclosed.

Abstract: A dental post having a support frame captured and interlocked thereon, and encaptured in a luting material, preferably such as a moldable self-curing tooth-colored composite material to create a laminated composite/metal foundation complex for retaining a dental rstoration securely on a tooth stub. The post includes a smooth cone-shape lower end portion for matchingly fitting into a prepared tooth canal, a threaded portion passively fitting in the tooth canal for engagement with the composite material, an unthreaded portion to provide greater strength, a square portion to permit the dental post to be unscrewed from the hardened composite material, a tapered portion, and a chisel-like portion at the upper end of the dental post. The support frame includes a pair of opposing legs for straddling the dental post and a bight portion connecting the legs together, the bight portion having a slot for receiving the chisel-like portion therethrough, a pair of pads extending transversely outwardly from the lower ends of the legs for seating in steps formed in the tooth stub, elongated slots formed in the legs to receive the composite material therethrough and to permit the bifurcated leg portions to be twisted to reinforce the structure of the legs. The chisel-like portion is inserted through the slot in the bight portion, and then turned 90 degrees to capture and interlock the dental post and the support frame together.

Abstract: The invention resides in a precise technique for determining the equivalent bit rate (EBR) of a variable bit rate (VBR) ATM connection. The technique extends a known single-source method developed by Gibbens and Hunt. The new technique applies to shared facilities and hence exploits the statistical-multiplexing gain. The calculation of the EBR is quite fast and is therefore suitable for real-time call-admission control in ATM switches. The admission criteria may be basd on either the cell loss or cell delay.

Abstract: A coil assembly for use in an inductive apparatus, is comprised of a conductive material, either copper or aluminum, continuously wound around a circular or rectangular shape. At a predetermined number of turns, a terminal or tap is formed in the conductor. The tap is essentially a bump in the conductor that will protrude from the coil and be accessible to make connections to it after the coil assembly is complete. The insulation of the conductor is removed from the outside edge of the bump to form a point of contact. A C-clamp, formed from spring steel or other conductive material, functions to secure an external conductor having a lug attached to an end of conductor to the formed terminal. A bolt through the lug is secured by a tapered depression in the C-clamp that functions as a nut. The C-clamp includes an extension that provides additional pressure between the point of contact and the lug to make an electrical contact with a portion of the formed tap and the lug. To provide an anti-rotation feature, the C-clamp also has corner ends that are formed downward over the lug.

Title: Cooking with spent liquor pretreatment of cellulose material
Inventor: HENRICSON KAJ O
IPC: D21C7/00
Filed: 1995-08-30
Granted: 2004-03-16
Abstract: A method and continuous digester system provide for a high Na2S concentratio n in the beginning of the cooking of comminuted cellulosic fibrous material to produce cellulose pulp, providing a more selective cooking and potential to lower cooking kappa. Two different streams of spent (e.g. "sulfurous" and "black") liquor are removed from different screens associated with continuous digesters. The spent liquor removed from the uppermost screen has a relatively high effective alkali and Na2S concentration. The second spent liquor, removed from the second screen, has effective alkali and Na2S concentrations which a re at least 25 % less than for the first spent liquor. The first spent liquor is circulated to an impregnation vessel, or other part of a chi p feed system, to enhance the amount of sulfur present at the beginning of the cooking stage in the digester. The second spent liquor may be used in a number of ways, including -- with or without first passing it through a flash tank -- circulating it to a chip slurrying system for slurrying the chips so that they can be fed to the digester. The steaming and slurrying system may include only an unpressurized chip bin, ch ip feeder, slurrying vessel, and high pressure feeder, thus being simpler than conventional constructions.

Abstract: A method and computer program product for overcoming the inefficiencies associated with inter-buffer data transfers between separate processing components such as kernel mode drivers that are chained together. Provided is a standard mechanism for allocating and managing data buffers needed for processing data in a system, wherein multiple drivers are chained together using a standardized connection method in the connection pin instances. Drivers having different buffer requirements and capabilities may be queried and matched for easy data transition between the chained drivers requiring the least number of buffers and, hence the least expensive yet most efficient inter-buffer data transfer. Examples of buffer requirements include previous frame storage for adaptive processing, byte alignment, frame size, outstanding frames allowed, etc. The buffer requirements of an input connection pin instance may be queried by an application initializing the chained drivers. When a buffer is needed, a buffer allocator will be associated with the input pin instance, otherwise a driver will process the data in the previous existing buffer.

Abstract: The invention provides a wavelength division multiplex communication link for optical transmissions, which is able to provide a ultra high bit-rate wavelength division multiplex communication at a 1550nm wavelength band using the existing 1300nm band zero dispersion of a single mode fiber network. A dispersion compensating fiber DCF having a negative dispersion value at a 1550nm wavelength band is connected to a single mode fiber SMF of the existing 1300nm band zero dispersion of a single mode fiber network with a line length which compensates the dispersion slope of the single mode fiber to zero. And, a dispersion flat fiber which makes the dispersion slope zero is further connected, with a line length which makes the remaining dispersion value zero, to the terminal end of a connection link of the single mode fiber SMF and dispersion compensating fiber DCF, whereby both the dispersion slope of a single mode fiber and dispersion value thereof can be adjusted to be zero at the terminal end of the dispersion flat fiber DFF.
