Apparatus and method are provided for supplying cellulose acetate tow for the manufacture of cigarette filters from the transport jet of a tow opener to a cigarette filter rodmaking garniture. The apparatus is a frustoconical member having a multiplicity of apertures in the wall thereof and is attached directly to the transport jet. The apparatus has an internal diameter the same size as the exit opening of the transport jet. The opposite end of the adapter is inserted into the tow intake of the garniture. Transport gas that is introduced by the transport jet escapes through apertures in the adapter wall as the tow enters the garniture intake. A closely fitting rotatable sleeve having apertures in the wall thereof can be used to reduce the escape of transport gas through the adapter wall for optimizing performance of the adapter with tows of various processing characteristics. Tow yield is improved and pressure drop variability is reduced.

Transport jet adapter

A process and apparatus for controlled application of a liquid to a variable width filamentary band such as a cigarette tow band. Liquid is fed at a constant rate by one or more positive displacement pumps to an applicator device which may be a disc type or a brush type applicator device. Any liquid which is not picked up from the applicator device by the tow band is returned by means of channels located in a housing member directly to the applicator device whereby variations in the width of the tow band do not substantially change tow liquid pick-up from a preselected weight level.

Process and apparatus for controlling distributing and monitoring liquids

An electrical power generating system is disclosed which utilizes as a source of energy the otherwise wasted energy expended by motor vehicles moving along a roadway. The system includes a vibrational transducer which is mounted in the roadway and which is constructed for producing electrical energy directly from the vibrational energy imparted to the transducer from the motor vehicles passing thereacross. The electrical energy thus produced may be used to charge a storage battery for powering various devices, such as traffic signals, warning devices, and the like.
