A device for preparation of a chemically reacting mixture, and for ejecting the mixture into a mold includes a pair of slides having transverse through openings capable of being mismatched upon relative reciprocation, oscillation and/or vibration of the slides for dynamically setting the mixing pressure.

In order to simultaneously fill several containers with a liquid, gaseous or solid flowable medium, without it being necessary to measure and monitor the filling volume or weight of each container, the filling apparatus has a pipe system (10) for carrying the medium to be filled. The pipe system includes a plurality of branch lines (13, 113, 213) leading to valves (20, 120, 220). In the branch lines there are arranged volume chambers (40, 140, 240) having impellers jointly placed on a shaft (41) with a system pressure-dependent braking device (45). The impellers are rotated by the medium flowing through the volume chambers. A balance (50) or a rotary piston meter (150) is associated with only one valve (20) of all the valves controlled by a control cylinder (25) and is used for controlling the latter.

A viscous liquid dispenser (1) having a dispensing container (6) with a dispenser bottom (2) having a multiplicity of drainage holes (3) a grooved track (5) within the inside wall of the dispensing container parallel to and above the dispenser bottom, and a slidable damming plate (4) having a multiplicity of drainage holes (3) which is mounted in the grooved track and is capable of sliding between a closed position (FIG. 2) wherein the drainage holes of the slidable damming plate and the dispenser bottom are not aligned and an open position (FIG. 3) wherein the drainage holes of the slidable damming plate and the dispenser bottom are aligned is provided.

A food depositing apparatus for depositing a semi-solid food product within a fixed area defined by a receptacle includes a depositing mechanism. The depositing mechanism includes an extrusion device having an opening through which semi-solid food product can be fed into the extrusion device. A pressure element coupled to a drive mechanism is configured to extrude the semi-solid food product from the extrusion device through an exit port. A valve located at the exit port is adapted to selectively control the flow of extruded semi-solid food product. An air knife positioned adjacent to the cutoff valve cuts the continuous stream of semi-solid food product into semi-solid food pieces. These pieces are deposited on the receptacle which is positioned on a scale. A control module is coupled to the scale and cutoff valve to control operation of the depositing mechanism. To deposit an amount of semi-solid food product whose total weight is within a preselected target weight range, a first amount of semi-solid food product is deposited on the receptacle and weighed to determine its precise weight. The precise weight is fed to the control module which then actuates the depositing mechanism for a second time if necessary to deposit a second amount of semi-solid food product on the receptacle. The total weight of the first and second amounts falls within .+-.10% of a desired target weight.

A variable throttling feed apparatus, commonly known as a slice for breaking down clumps of fiber in various fiber processes, comprises a rotatable half round feed aperture bar which cooperates with the side of a cross flow feed chamber to form both a portion of the wall of that chamber when rotated in one direction to facilitate cleaning and a variable slice when rotated to partially open positions which permit the fiber to flow from the cross flow channel along its length.
