Abstract: An apparatus (10) for feeding sliders (31) from a source of sliders to the slider insertion area (27) of at least two slider insertion devices (18, 19). A sensor (30, 52) on a sender track (20, 21) detects a lack of sliders (31) in the sender track.

Abstract: A system for transporting ice pieces or the like from a primary bin to one or more satellite bins is disclosed. A dispenser forms a charge of ice pieces in a precharge chamber, which is then transferred by air assist to a delivery tube. A driver member is provided to engage and move the substantially defined charge of ice pieces to the selected satellite bin. The driver member is propelled by a differential pressure within the tube. This permits the defined charge to be exposed only to the low pressure side and insulated from the high pressure propelling medium to minimize breakage and melting during delivery. Before reaching the satellite bin, the piston is reversed to shuttle back to the home position. The satellite bins are connected in series and delivery of a charge to an intermediate bin is provided by moving a tube section out of alignment with the delivery tube. Lubrication and continuous cleaning is performed by the driver member sweeping minimal residual water from melting ice.

Abstract: Pneumatic conveying apparatus and method are described to provide for a simple, economical, convenient (and preferably automatic) system for conveying small pieces of frozen food (e.g., chopped vegetables, diced meat, or preferably ice cubes or crushed ice) on an as-required basis to one or more locations remote from a food source.

Abstract: Apparatus for conveying filter rod sections from storage or from a maker to a reservoir or to a filter tipping machine for cigarettes or other rod-shaped articles of the tobacco processing industry has a first conveyor which advances the filter rod sections lengthwise, a second conveyor which advances the sections sideways, and a unit which transfers successive sections of a series of sections delivered by the first conveyor to the second conveyor. The advancement of sections by the first conveyor is interrupted if the spacing between successive sections in the first conveyor is less than required for disturbance-free transfer of sections from the first conveyor into the second conveyor. One or more sensors are provided to minitor the movements of sections at the transfer unit and to generate signals which are utilized to remove sections from the transfer unit when the pattern of movement of sections from the first conveyor to the second conveyor departs from a desired pattern.

Abstract: A pneumatic filter transport system has a gate (18) in a section of conveying duct (2), which gate and is openable in response to signals indicating a filter rod jam in a receiver unit (15) connected to the duct. Once opened, the gate allows remaining filters in the duct to be directed to a dump (30): this reduces the risk of a receiver jam developing into a line jam (which is more difficult to clear). The gate may be provided in a curved section of duct just upstream of the receiver. The duct may incorporate a longitudinally-extending partition (60), which allows removal from the duct of loose material (e.g., carbon granules) which has become separated from the conveyed filters. The duct may have longitudinal slots (68) which allow conveying air to exhaust from the duct upstream of the receiver.

The air and accompanying material are fed to a distribution pipe with multiple flexible downward projecting fill spouts which are spaced at regular intervals. Each spout has an associated control valve and air pressure sensor within the spout, so that as a container being loaded by the spout is filled, and the pressure in the spout increases beyond a preselected level, the spout is closed off and material automatically is transported to the next open spout. Air operated spreader heads may also be furnished at the lower ends of the spouts to assure that the container volumes are completely filled.

Abstract: To limit the amount of solid particulate matter fed into an airlift pipeline from, especially, a suction nozzle device, the density of the suspension passing from the suction nozzle to the airlift system is measured. If the measured density is above a predetermined value, a proportion of the suspended solid material is removed prior to passing into the airlift pipe.The density of the moving suspension is determined by a radiation-type densitometer located upstream from the airlift pipe. The density can also be directly measured by a balance beam or weighing arrangement connected to a pivotable length of pipe. Where fine particles are present that are not to be considered in the densitometer measurement, a differential measurement can be obtained by a second measurement of the density of liquid from which the large particles have been screened.
