A front opening cigarette box comprises a container portion and an integral cover portion which articulates between opened and closed positions. The container portion includes a front face, a rear face generally parallel to the front face, a bottom face, and spaced apart side walls interconnecting the front and rear faces. The cover portion includes a front face that fully covers the container portion when the cover portion is in its closed position. The cover portion also includes top and bottom faces, and a rear face contiguous with and forming a continuation of the rear face of the container portion when the cover portion is in its closed position. Spaced apart side walls on the cover portion interconnect the front and rear faces thereof. A hinge line extends between the rear faces of the container and cover portions, and the cover portion articulates about that hinge line between its opened and closed positions. Such front opening cigarette box provides easy access to the individual cigarettes within the container portion and total access to the upper ends of the individual cigarettes when the cover portion is in its opened position.

An apparatus for controlling operation of a processing machine has a computer preferably with a computer aided design program configurable to model a kinematic velocity profile of a point of interest on a machine to be controlled. A graphical user interface on the computer enables an operator to select desired velocity points for a motor drive controlling motion of the point on the machine. A curve fit is applied to the velocity points to realize a desired velocity profile for the motor drive and the point on the machine. The desired velocity profile is then integrated and scaled in order to obtain a scaled velocity profile that realizes an actual, or target displacement of the point as dictated by operation of the machine. By controlling operation of elements of a machine with velocity profiles, coordination of associated elements and points on the machine can be visualized by an operator selecting the velocity points for each drive of the machine. A method for implementing same is also disclosed.

An integral formed fluted tube intended, for example, for use as a sound suppression device in mufflers, exhaust ejectors, etc. is disclosed. The tube is formed of a cylindrical portion with generally circular inlets and outlets and a constricted portion between those ends and within the constriction, a plurality of bypasses therethrough. The constriction may also include a frontal portion having a generally concave surface which rises to an apex and thereafter forms a plurality of convex rear portions toward the outlet end. Other embodiments are shown in the Figures. The device may be used integrally within a muffler to obtain a venturi effect for an exhaust ejector and sound suppressor.
