Inventor: GRAUDEJUS WOLFGANG
IPC: A24C5/343
Filed: 1990-07-23
Abstract: A method and an apparatus for determining the filling capacity of tobacco are described.  A predetermined quantity of tobacco (R) is filled into a volume of known cross-section, closed on one side by a movable plunger (2), and the length of the tobacco column and the force acting on the tobacco via the plunger (2) are measured as a function of time.  The data are acquired and processed automatically by at  least one computer while the tobacco is being packed into packaging containers (22A) by means of a press, or during an additional pressing by a press after packing.  The length of the tobacco column is determined from the measured (52, 54) distance covered by the movable plunger (2) of the press which compresses the tobacco (R) and in doing so moves it into the packaging container (22A), or which carries out the additional pressing of the tobacco.  The force acting on the tobacco is measured from the pressure (57) required to drive the plunger (2), or from the supporting force (56) required to hold the packaging container (22A), or from the force occurring at the plunger or its drive elements. Additional parameters governing the value of the filling capacity are determined in independent measurements (60, 62) and fed into the computer. The method is preferably applied to leaf tobacco.

Patent CA-2024643-A1 (CA)
Inventor: LEBLANC GEORGE W JR
IPC: B63C9/32
Filed: 1990-09-05
Abstract: ABSTRACT     The invention provides an inflatable rescue ramp hav-ing a pair of spaced inflatable tubes which join at one end to define a bow.  A flexible web is mounted between and connects to the tubes at outside seams.  That is, the web passes under each tube and is attached thereto on outside longitudinal seams, such that downward pressure on the web or ramp floor will cause adjacent portions of the tubes to axially rotate outwardly from each other to provide and enhance passageway on the web between the tubes.  The rescue ramp is carried to the scene in a folded and compact state, with the above tubes being con-nected to a compressed air source.  The rescue ramp is positioned on or near a firm surface and pointed toward a victim on an unfirm surface e.g. in an icy pond and the tubes inflated causing the ramp to pop or snake out of its packed condition and extend toward the victim with anchor lines from the tubes trailing.  The rescuers grab the anchor lines and aim or position the inflating or inflated rescue ramp in the direction of the victim and then secure the anchor lines and the near end of the res-cue ramp on or near a firm surface e.g. the shore of a pond, whereupon a rescuer can hurry out on the so-positioned ramp to aid the victim.  Subsequently, the rescue ramp is deflated, folded and packed for future use.
