Abstract: The invention relates to low delivery cigarettes, usually having a mainstream particulate matter delivery of about 9mg or less. The cigarettes(1) comprise a rod (2) of tobacco material and a filter element (3). The filter element (3) comprises an alkali filter material section (4) having a loading level of less than 12% by weight of the section. The characteristics of the cigarettes (1) are arranged so that, when smoked, the alkaline filter material is exposed to an amount of smoke acceptable to achieve an increased perception of smoke impact. This is usually achieved by using a low particulate matter potential rod. In this way the moisture free dry particulate matter (NFDPM) to nicotine ratio is decreased compared with control cigarettes having the same cigarette characteristics without the addition of alkaline filter material to the filter element. <IMAGE>

Abstract: The pressure medium drive is provided for opening and closing the contacts (e1, e2) of an electric circuit-breaker. It contains a pressure medium reservoir (r), a drive piston (t) which slides in a drive cylinder (c) and acts on a mechanism (j) for displacing a movable contact (e1) of the circuit-breaker, and a reversing valve (s) for the selective connection of the pressure medium reservoir (r) to the drive cylinder (c) or of the drive cylinder (c) to an outlet volume for the pressure medium. This pressure medium drive is of simple, inexpensive construction and can open the contacts of the circuit-breaker considerably faster than it can close them. This is due to an interposed valve (v) which is disposed between the pressure medium reservoir (r) and the reversing valve (s) and has a flow cross section determined by the closing time of the contacts (e1, e2), and to the much larger flow cross section of the reversing valve (s). This interposed valve (v) is open when closing the contacts (e1, e2) and passes pressure medium from the pressure medium reservoir (r) via the reversing valve (s) into the drive cylinder (c). After closing of the contacts (e1, e2), it is closed and then establishes the connection between the drive cylinder (c) and the outlet volume by reversing the reversing valve (s).

Abstract: A high speed and memory efficient system and method for rendering Bézier curves. The system utilizes a hybrid forward differencing function representing the Bézier curve defined by the Bézier control points and renders the curve with a small number of straight line segments. The system renders the curve in a manner that results in the same Bézier control points that are calculated using the prior art recursive subdivision techniques and rejects line segment approximations that would not be derived from recursive subdivision. The system can start at either end of a Bézier curve and will render the same approximation. The method is readily implemented on a computer and is applicable to Bézier curves of any order. <IMAGE>

Abstract: Method and apparatus for the treatment of fluids, particularly wine, to remove unwanted substances. The wine is treated in a reverse osmosis (R.O.) treatment unit, generating a retentate and a raw permeate. The membrane for the R.O. unit is selected to pass in the permeate the unwanted substances, such as volatile acidity (ethyl acetate and acetic acid). The raw permeate is subjected to a treatment column. In the case of volatile acidity, this is an anion exchange column, which removes the acetic acid from the permeate by anion exchange and removes the ethyl acetate by base hydrolysis. This produces a purified permeate, which is depleted in volatile acidity, but contains other components desirable for the wine. The purified permeate is then recombined with the retentate from the R.O. column, and the result is wine with the volatile acidity and little else removed. This wine may be recirculated through the system to remove yet more of the volatile acidity. Before the anion exchange step, a low-energy distillation may be used to remove CO2, H2S, or other relatively volatile compounds. To remove acetaldehyde, a low-energy distillation column is used instead of the anion exchange column, and the distillation residue constitutes the purified permeate that is recombined with the retentate from the R.O. column. A high-energy distillation column may be used to separate out alcohol and water, and then add either the alcohol or the water back to the R.O. retentate, thus producing either a higher alcohol or a lower alcohol beverage.

Abstract: This invention relates to an improved arterial catheterization system which is designed to allow the user to quickly visualize the early flashback of blood after penetration of a vessel. The improved arterial catheterization system of this invention allows for minimum blood loss during initial penetration of the blood vessel. Specifically, this invention is directed to a system for introducing an over-the-needle catheter into a blood vessel, and comprises an inserter unit having a hollow needle and a catheter having a lumen such that the catheter is adapted to be carried on the needle. The catheter and needle cooperate to form a first flashback chamber therebetween. The first flashback chamber is at least partially translucent and allows for the visualization of blood flow upon insertion of the needle into a blood vessel. A guide wire, which is slidably mounted on the inserter unit within the needle, is dimensioned in relation to the needle in order to provide a blood flow passage therebetween. A second flashback chamber is formed in the inserter unit and connected to the needle to receive blood flow. The guide wire serves as a guide for the catheter as the catheter is advanced off of the needle, along the guide wire and into the blood vessel. The guide wire and the catheter are separable after the catheter is placed in the blood vessel.
