Abstract: A controls stage, a hopper stage, and a pneumatic stage are arranged to govern the movement of particulate additives from a hopper through a receptacle that communicates with a delivery tube with the particles exiting the delivery tube via an outlet and contacting products or commodities such as food products. Embodiments include those wherein the use of air flow through the delivery tube is responsible for ushering particulate additives out of the delivery tube, with or without a secondary air flow to facilitate movement of particulate additives into the delivery tube, and a notched disc controlling the opening and closing of a valve to allow or restrict particulates from passing, wherein the size and quantity of notches affects the frequency at which particulate additives move from the hopper into the delivery tube.

In addition, a lip can be provided outwardly of the spillway for dissipating the kinetic energy of the water spilling from the splash pad.

Abstract: An apparatus for vacuum transferring food product having a hopper for retaining food product, the hopper including a discharge port; a vacuum chamber having an inlet and an outlet, wherein the inlet is coupled to the hopper at the hopper's discharge port; a vacuum source for inducing a vacuum pressure between the hopper and the vacuum chamber so as to cause food product retained by the hopper to be drawn into the vacuum chamber though the inlet; a first timing circuit for controlling the length of time that the vacuum pressure is to be applied between the hopper and the vacuum chamber; and a second timing circuit for controlling the rate at which the food product is dispensed from the outlet. The first timing circuit may be adjusted to increase or decrease the length of time that the vacuum pressure is drawn though the apparatus, and the second timing circuit may be adjusted to increase or decrease the frequency of the opening of the outlet.

Abstract: The invention relates to the field of conveyors for containers of plastic, for example PET, with protruding neck rings. In particular, the apparatus (1) comprises a supporting structure (4) that mounts a track (5) which supports the containers by their neck rings (3). The apparatus further comprises means for propelling the containers along the feed path and means for detecting jammed containers along the feed path.

The central column has a closed top and an open bottom. Each tube has a lower, intake end, a lower first air injector and an upper second air injector. Each air injector is comprised of a housing disposed around an air injection section of the transport tube in which is mounted a first or second air jet, respectively. Compressed air is supplied to the first air injector via an air supply line and to the second air injector via an air supply line and the central column.

Abstract: An improved method and related system for pneumatically transporting powdered or granular materials stored in an airtight storage container to a collector through a transport pipe in the form of a lengthy column in high density and at a slow speed by the use of pressurized gas. The method of the invention comprises the steps of stopping feeding of the pressurized gas when the whole of the powdered or granular materials corresponding to a final batch contained in the storage container are sent into the material transport pipe, simultaneously discharging the internal pressure of the storage container through a gas decompressing means, inserting a transport plug from the base end of the material transport pipe, and carrying forward the transport plug at a slow speed by feeding pressurized gas from the base end of the transport pipe.
