Abstract: Cigarettes which yield low levels of visible sidestream smoke upon use employ an outer paper wrapping material including magnesium hydroxide, calcium carbonate and flax fibers. The outer wrapping material has an inherent permeability of about 10 CORESTA units. The wrapping material contains an amount of water soluble alkali metal salt sufficient to provide at least about 30 mg water soluble alkali metal ions per gram of dry base web. The alkali metal salt normally is such that the wrapping material includes a significantly greater level of potassium ions than sodium ions. The cigarettes also employ an inner paper wrapping material including carbonaceous material and/or tobacco.

Abstract: A tobacco product consists of a preportioned tobacco strand (10) surrounded by a preformed tubular cigarette paper wrapper (11; 17). The tobacco strand is formed of individual tobacco fibers which are interconnected to each other by a binding agent to form a dimensionally stable tobacco strand. The binding agent and the fibers are each smokable but the outer surface of the tubular dimensionally stable tobacco strand is air pervious so that the strand as such is not directly smokable. The dimensionally stable strand (10) is inserted into the preformed tubular cigarette paper wrapper (11) to form a smokable cigarette. The one end of the strand is tapered for easier insertion of the strand into the preformed cigarette paper wrapper.

Abstract: Apparatus for feeding tobacco particles to one or two cigarette rod making machines has a magazine with a duct having an open lower end above the upper reach of an endless belt conveyor. The conveyor can be driven to advance tobacco particles in the duct toward an outlet of the magazine where the particles are removed by one or more rotors which are driven to move the particles upwardly and away from the upper reach of the conveyor before the particles are caused or permitted to descend into a hopper. The bottom portion of the hopper admits tobacco particles into one of two suction-operated pneumatic conveyors each of which supplies tobacco particles to a discrete rod making machine. The conveyor is driven at a first speed when the hopper supplies tobacco particles to a single rod making machine, and at twice the first speed when the hopper supplies tobacco particles to two rod making machines.

Abstract: A retractable surgical or other instrument is provided with a locking mechanism automatically actuated by sliding an operating element forward to extend it from a protective sheath. The locking mechanism operates by the cooperative action of a plurality of abutment means integrally molded into the interior of the instrument handle and a plurality of transverse bends forming a substantially closed loop profile in the proximal end of the elongated support shaft of the operating element. A longitudinally slidable actuating pin engages the proximal end of the support shaft to move it longitudinally in a selected direction. A portion of the proximal end of the shaft is biased to exert a radially outward force on the inner wall of the instrument handle thereby assuring positive engagement between the support shaft and an abutment surface which prevents rearward motion of the surgical element once it is placed in an extended position.

Abstract: The joint structure of the present invention includes a flexible tube constructed of a coil-wound metal wire element and of another member. This other member includes 1) a main joint joining the end of the outer peripheral surface of the flexible tube to the end of the other member by laser welding either part or all of the main joint; and 2) spot welds joining together adjacent turns of the coil in the vicinity of the main joint by irradiating a laser beam onto a plurality of separate spots extending over the adjacent turns. A handling device for use in endoscopes having such a structure and a similar structure, in which the other member is also a flexible tube either softer or harder than the above flexible tube, is also discussed. Adjacent turns of the coil in the vicinity of each of the welded joints are laser spot-welded at a number of spots, thereby strengthening the thermally affected regions during the laser welding of the joints and increasing the rigidity of the region.

Abstract: A container for containing an additive material for modifying the characteristics of a smoking article. The container contains at least two components that are movable between a first position and a second position with respect to each other. In the first position the additive material is hermetically sealed inside the container during storage of the smoking article prior to use. The container is activated by moving the components of the container to the second position to provide air flow pathways through the container so that the additive material can modify the smoking article accordingly. The components may have perforations that are covered by cooperating overlapping portions of the components of the container in the first position and uncovered in the second position. Alternately, the container may include a sealed capsule containing the additive that is punctured by moving the components during activation.

Abstract: In a device ensuring safety and protection around the unit by which a cigarette rod is dried and sealed in cigarette manufacturing machinery, a hinged guard is positioned alongside the area of the machine where the heat plate of the drying and sealing unit moves and operates; the guard is capable of movement between a shut position denying access to the operating area and a position whereby access is afforded to the area. A microswitch senses when the guard is in the shut position, denying access to the operating area, and relays an enabling signal to the control valve piloting the cylinder by which the heat plate is lowered, only when the guard is in this same safe position.

Abstract: To facilitate certain surgical procedures, a flexible endoscope may more readily be passed through body vessels and tubular organs, especially when those organs assume a tortuous path. However, a difficulty arises in steering a flexible endoscope through internal body orifices. In accordance with the present invention, a rigid introducer is used in combination with the flexible endoscope to facilitate targeting of such an orifice and once the distal end of the introducer is made to enter the orifice, the flexible endoscope can be advanced through the introducer and there beyond to the point in the body where an item of interest is to be viewed.

Abstract: The combined mass flow of solid and liquid fractions of a fibrous material which is converted into a tobacco rod or filter rod in a rod making machine of the tobacco processing industry is ascertained by monitoring the liquid fraction in the distributor of the machine and by monitoring the solid fraction downstream of the monitoring station for the liquid fraction. Electric signals which are obtained as a result of such monitoring are processed in a computer which transmits a signal denoting the combined mass flow of solid and liquid fractions. Such signal is used to maintain the combined mass flow at or close to a preselected value, particularly by adjusting a trimming device which removes the surplus of fibrous material ahead of the station where the fibrous material is draped into a web of cigarette paper, imitation cork or other wrapping material.

Abstract: An insert for supporting a double ended needle during a blood collection procedure is translatably mounted within a cylinder for retracting the anterior needle into the cylinder on completion of the procedure to prevent needle stick while the posterior needle remains continually shielded against needle stick by the insert. An anterior lock position stabilizes the double ended needle during the blood collection procedure and a posterior lock position retains both ends of the needle shielded. A ramp may be associated with the posterior lock position to prevent further translation of the insert and reuse of the holder. For a reusable holder embodiment, the used double ended needle is retracted, safely enclosed and locked inside the cylinder. The anterior end of the cylinder is adapted for receiving the open end of a conventional needle shield to permit gripping of the needle supporting hub and disengagement of the needle from the insert without exposure to needle stick.
