摘要:
A method of transferring objects onto a substrate, or a moving substrate, the objects to be transferred being placed in a transfer area including an inlet and an outlet spaced apart from one another by two lateral edges opposite one another, and holding a carrier liquid forming a conveyor, the objects being held by a compact film of particles floating on the carrier liquid of the transfer area, in which the objects are moved with the particle film to be transferred onto the substrate when they reach the outlet.
摘要:
Disclosed is a method for rendering vacuum conveyors inert, the vacuum conveyors including at least one intake device (30), a discharge device (40), a separating vessel (100), a vacuum pump device (20), and a system for feeding inert fluid into the separating vessel (100). An inert fluid is fed into the at least one separating vessel (100) below the free surface of a separated material (102) during inertization. A corresponding vacuum conveyor (10) which can be rendered inert includes a system for feeding inert fluid below the free surface (103) of a separated material on and/or in the at least one separating vessel (100).
摘要:
The grit used for blast-scouring the interior of a tank or compartment in a ship, accessible only through a manhole, is entrained and raised by suction off the floor of the tank by a small distance, and is thereupon entrained and conveyed to the level of a deck above the tank by pneumatic pressure.
摘要:
Particulate material is conveyed upwardly in a gas stream in an elongated casing, with the gas stream having a velocity less than the conventional choking velocity, by having gas and particle stream deflecting elements, such as wire mesh cylinders, randomly disposed along the length of the casing.
摘要:
A device for conveying fowl from one point to another includes a conveyor chamber through which air under pressure is forced, a fowl inlet to the chamber having a conduit section extending longitudinally downstream and terminating within the chamber and conduit means exiting from the chamber and having an upstream end positioned closely adjacent but longitudinally spaced apart from the termination of the conduit section of the fowl inlet. A flow separator disposed within the chamber upstream of the termination causes the air to accelerate in flowing thereabout and to thereby create an area of reduced static pressure at the termination of the conduit portion.
摘要:
Live chickens are conveyed through a conduit including a suction intake section connected to a pressure discharge section by an intermediate section having an air suction port, a pivotable door, and an air pressure port within each end portion. Air is alternately sucked through the suction ports and is alternately blown through the pressure ports by operation of a valve system actuated in response to a device which sense the presence of each chicken within the conduit. The pressure within the discharge conduit section is sensed for controlling the flow rate of the air blown through the discharge section to assure that the chickens flow at a substantially uniform rate through the duct.
