Title: Extrusion machine for rods esp. cigarettes - has material flow measuring device between parting mechanism and discharge conveyor
Inventor: LORENZEN HEINZ-CHRISTIAN DIPL
IPC: A24C5/34
Filed: 1976-02-25
Abstract: The extrusion machine forms rod-shaped items such as cigarettes, having a continuous feed mechanism for a stream of material which is continuously wrapped, the wrapping being glued into place. Downstream of the wrapping mechanism the items are parted off and conveyed away. A measuring device (27) monitors the flow of material, and is mounted between the parting mechanism (21) and the discharge conveyor (24, 26). It can be equipped with a beta-ray source. Compared with existing designs, the advantage is that vibrations in the transverse direction are not transmitted to the items, and there is less likelihood of condensate being deposited in the guide tube, so that the measuring device is far more accurate.

Title: Air filter leaf for pneumatic instruments - with double layer bonded gasket preformed with multiple air passages
Inventor: NAWROCKI LEO
IPC: B01D46/10
Filed: 1976-10-16
Abstract: A fine mesh gauze has sealant bonded to each side to form gaskets, with areas left uncovered to form multiple air passages. To produce such a filter, the gauze is placed in a mould of two-piece construction, closing at the edges. Where an area of the gauze is to be left open i.e. not covered with the sealant, the perimeter of such an area is nipped by suitable projections in the mould to close the mesh around the edge of the area. When the sealant is then injected into the mould it cannot flow pass these nipped surrounds and the appropriate areas of the gauze are left clear to serve as air passages. Simple and inexpensive filter for the multiple air flow streams required at a pneumatic controller, avoiding the need for separate filters in each individual streams and is easily produced.
