Abstract: An improved endoscope having a flexible tip portion with both a selectable angle of deflection, and a selectable radius of curvature to provide a more maneuverable endoscope for use by a physician. It includes a body member receiving a rigid tube within a lumen thereof. The tube extends toward, but short of the distal end of the body member to define a deflectable tip portion. A pull-wire is positioned within the rigid tube and lumen and extends from the body member's proximal end to the body member's distal end. By selectively retracting the pull-wire in the proximal direction, the distal end of the flexible tip portion is deflected about the distal end of the rigid tube. In an alternative embodiment of the invention, a second rigid tube is telescopingly received within the first rigid tube. The second tube is selectively extendable beyond the distal end of the first rigid tube into the lumen of the body member.

Abstract: A disinfestation system for agricultural products, for example recovered tobacco, comprises a disinfestation unit which is releasably connected to plural containers. The disinfestation unit supplies a disinfestation gas (CO.sub.2) through the conduit means to the container, and periodically withdraws sample gas from said container.

Abstract: A hollow lumen cable is formed by helically winding inner and outer coils with the helices of each coil being in an abutting relationship and the outer coil inner peripheral diameter being less than the outer peripheral diameter of the inner coil. Preferably, each coil is multifilar. After the coils are wound, an unwinding force is applied to the outer coil and the inner coil is inserted into the outer coil to have its winding inclined opposite to that of the outer coil; and thence, the outer coil is allowed to contract to form an interference fit with the inner coil. The cable may be incorporated as part of a medical apparatus. The cable is bendable about the tight radii and has a high torque transfer resolution while having a small cable outer diameter, a relatively long life, and has a hollow lumen in which there is no structure or through which fluid, wires or medical devices may pass.

Abstract: A cigarette rod making machine wherein the apparatus which supplies tobacco particles to the stream building zone at the underside of a belt conveyor is designed to prevent entry of fragments of tobacco ribs into the outer layer of the stream. This is achieved by directing fragments of tobacco ribs into that portion of the stream which is to form the core of the filler of the cigarette rod and/or by directing fragments of tobacco ribs into that portion of the stream which is removed by a trimming device ahead of the station where the thus obtained filler is draped into a web of cigarette paper. Absence of fragments of tobacco ribs in the outer layer of the filler reduces the likelihood of piercing the web of cigarette paper at the wrapping station.

Abstract: It is a problem with hinge lid packs for cigarettes, that the pack content (cigarette block 29) often has a smaller depth than the interior space of the pack, so that the cigarette block (29) has to be supported by a filling piece.
