Abstract:
A feed mechanism in which a ram (2) fed from a hopper (1) compresses a fuel against a closed valve (11) which is then opened for the ram to push the fuel towards a rotary scroll (6) for delivery to a processing vessel.
Abstract:
The invention relates to a machining apparatus (1) having a frame (2) for the machining of a workpiece (3) that has a tool holder (4) that is mounted such that it can be shifted in a straight line in three axial directions (x, y, z) relative to a workpiece support (5) that is mounted beneath the tool holder (4), the workpiece support (5) being designed such that it can swivel the workpiece (3) about at least one axis (A, B). For improving the applicability of the machining apparatus, this machining apparatus according to the invention is characterized by a workpiece-holding table (6) that is designed such that it bridges the workpiece support (5) and can thus be firmly attached to the frame (2).
Abstract:
The present invention relates to a method and apparatus for drying particulate materials such as seeds and grains in which an air dryer having a shape of a vertical, cylinder and at least one drying stage with a mesh screen disposed therein with a horizontal mesh screen. An upwardly vertical air flow having a velocity in the mesh openings at least equal or larger than to the suspension speed of the particles to be dried temporarily suspends the particles until enough accumulate to provide sufficient weight or downward pressure for the particles to overcome the upward air flow, pass downward through one or more mesh screens and reach the bottom of the dryer.
Abstract:
A pop-up straw having an upper buoyant section and a lower flexible section is mounted within a container. When the container is opened, the upper end of the pop-up straw rises through the opening. The straw is particularly useful with a push in tab easy open end container. A collar which holds the upper portion of the straw is mounted below the opening and just below the downward extension of the tab. Opening the tab pushes downward against the upper end of the straw until the tab clears the upper end of the straw. The upper end of the straws then pops up through the opening.
Abstract:
The invention provides a colon cleansing solution comprising: a) 300 to 2000 mmol per litre ascorbate anion provided by ascorbic acid, one or more salts of ascorbic acid, or a mixture thereof; and b) 10 to 200 g per litre polyethylene glycol. The invention also provides methods and kits associated with, or making use of the solutions. The invention also provides a method of cleansing the colon of a subject comprising: — administering to the subject an effective amount of a first cleansing solution; and then after a time interval-administering to the subject an effective amount of a second cleansing solution, where in the two cleansing solutions are as described in the specification.

Abstract:
A first stage chamber has upwardly diverging walls so that an upward airstream has different air velocities at different heights in the chamber. When particles such as seeds are fed homogeneously along the chamber top length, they reach equilibrium at different heights depending on their weights and volatilities. The particles suspended and classified at different heights are conveyed by a horizontal airstream in parallel horizontal channels toward a chamber side wall, where they are removed by suction. Ribbed sections adjacent to the channels divide the chamber into deviating cascaded pathways, where the upward air velocity is homogenized and an opposite horizontal airstream conveys falling particles toward the side wall opposite to that on which the particles are removed, to thereby homogenize the spread of particles in the chamber. Light trash is removed through a convergent top section toward a cyclone. Heavy particles not suspended in the chamber are collected and removed at the chamber bottom. A second stage receives the particles removed at a sidewall of the first stage and performs a further separation by ballistically projecting the particles into one of two groups depending on the adjustable horizontal extent of the ballistic projection of the particles.
Abstract:
A chamber has upwardly diverging walls so that an upward airstream has different air speeds at different heights in the chamber. When particles such as seeds are put into the chamber, they reach equilibrium at different heights depending on their weights. A horizontal conveyor airstream, much less in magnitude than the upward airstream, directs the classified-by-height particles to a side wall of the chamber, where they are removed.
