Title: Pneumatic testing apparatus for cigarettes or the like
Inventor: KOCH FRANZ-PETER
IPC: A24C5/32
Filed: 1984-04-19
Abstract: Apparatus for testing the wrappers of filter cigarettes in a filter tipping machine has a drum-shaped conveyor with peripheral flutes which transport a succession of cigarettes through a testing station where the ends of successive cigarettes receive compressed air to establish a pressure differential between the interior and the exterior of satisfactory wrappers. At the testing station, the ends of the cigarettes are sealed from the atmosphere by first sealing devices having elastically deformable annular portions surrounding the filters of the cigarettes in the regions adjacent to the respective end faces and second sealing devices having elastically deformable membranes engaging the end faces of the tobacco containing portions of the cigarettes. The air is caused to flow through openings which are provided in the sealing devices. Such selection of sealing devices ensures that minor defects at those ends of the wrappers which surround the filters do not result in segregation of corresponding cigarettes from other cigarettes. Segregation is effected automatically by monitoring the pressure differential between the interior and the exterior of each wrapper at the testing station and by ejecting cigarettes whose wrappers permit excessive quantities of air to flow therethrough or therearound. <IMAGE>

Patent GB-2171781-A (GB)
Title: Automatic one-way fluid valves
Inventor: ANDREN CHRISTOPHER ERIK
IPC: F16K15/14
Filed: 1986-01-20
Abstract: One automatic one-way fluid valve comprises a cylindrical valve tube (510) in which a cup-shaped diaphragm (540) is carried on radial supporting fins (524). The diaphragm (540) comprises a cylindrical side wall (542) extending from a closed end wall (544), and has externally near the free end of the side wall (542) a sealing surface which engages with, and presses by virtue of the inherent resilience of the diaphragm (540), against an annular sealing ridge (522) formed internally within the valve tube (510). An end cap (512) and dust barrier (538) carried on the free end of the valve tube (510) protect the mating valve sealing surfaces against contamination. In another such valve, (Fig. 3) a radial inlet throat (50) is defined by annular seatings (48,46) spaced axially apart and formed on a valve tube (14) and on an end closure cap (12). A thin, tubular, elastomeric valve diaphragm (52) presses resiliently at its respective borders against the seatings so as to close the throat and prevent fluid flow between the valve tube and inlet passages which communicate with the throat. A fall in fluid pressure in the valve tube below that in said throat withdraws parts of the diaphragm from at least one of the seatings to admit fluid to the valve tube. External fins (20) and internal fingers (36,38) limit the deformation of the diaphragm. In Figs. 5 and 6 (not shown), the diaphragm (138,238) is frusto-conical and closes a frusto-conical throat (142,240), one border of the diaphragm being held firmly against one seating (140,232), and the other border pressing resiliently against the other seating (126,222). Modified forms of those several valves are described. <IMAGE>

Title: Improvements in and relating to proportioning of constituents of a mixture
Inventor: HART BERNARD EATON
IPC: B01F5/04
Filed: 1987-03-05
Abstract: The proportion of liquid and particulate material in a liquid/ particulate material mixture supplied to a system in which the mixture is drawn into the system by suction, e.g. a gun producing an abrasive jet as described in GB.2116637, is variable. A duct (10) has a first inlet (11) for liquid, an outlet (13) for the liquid/particulate material mixture and openings (12a) opening laterally into duct (10) downstream of inlet (11) for particulate material. In use a variable quantity of liquid is supplied to inlet (11) variation being effected by means of a control valve. It is found that with this arrangement liquid is preferentially drawn through duct (10) by the suction created by the system so that a variation in the quantity of liquid supplied to inlet (11) will produce an inverse variation in the quantity of particulate material drawn in through inlets (12a) to produce a corresponding variation in the proportions of liquid and particulate material drawn out of outlet (13). <IMAGE>
