Title: Controlling a sample fluid flow or volume a carrier fluid
IPC: G01N30/02
Filed: 1980-09-25
Abstract: Acoustic standing waves are used to impede the flow of a sample fluid relative to a carrier fluid, eg in chromatographic analysis. A controlled source 12 of a carrier fluid feeds a carrier fluid to one end of a tube 2. A source 20 of sample fluid is connected to an inlet port 14 at a location between two adjacent nodes 36 in a standing wave generated by an acoustic signal generator 4. The sample fluid flows across tube 2 to an exit port 24 and satwates the fixed volume between the nodes to provide a sample of predetermined volume. Cessation or reduction of the standing waves then allows the carrier gas flow to sweep the sample out of the other end of tube 2. That end of the tube is connected to a chromatographic column 30 with an associated detector 32. The column 30 has a sonic generator 42 which produce a standing wave pattern in the column 30, the nodes of this pattern acting as separation plates in the column. <IMAGE>

Title: Process for Recovering Starch Slurries and Gluten from Starch- bearing Materials
IPC: C08B30/04
Filed: 1981-03-25
Abstract: A process for recovering a starch slurry and gluten from a starch- bearing material such as corn, potatoes or wheat, is characterized in that water being used in the process is separated, e.g. by reverse osmosis, into two fractions, including a first fraction (permeat) of low solubles and insolubles content which is recycled and used together with fresh water for washing the starch. In Figure 3, water containing gluten from the primary separation station of a corn wet milling process is separated by reverse osmosis into a first fraction which is recycled and used to wash starch, and a second fraction which passes to a gluten concentrator. The separation step reduces the water requirements of the process and reduces the volume of effluent for evaporation or disposal. <IMAGE>

Title: Producing mixtures of thermoplastic synthetic resins and mineral or organic fillers
IPC: B01F23/57
Filed: 1981-05-08
Abstract: In a method for producing mixtures of thermoplastic synthetic materials and mineral or organic charge materials, the materials are vacuum mixed and compressed. According to the invention, the mixtures of synthetic materials and charge materials are already homogeneous in a powder state. They are also resistant without granulation to disaggregation, they are stable and can be shaped as products. Moreover, the rigidity must be obviously high but without fragility. The values of the resistance must approach those of the pure synthetic material. Finally, commercial advantages must be attained. To these purposes, the charge materials must be electrically or electrostatically charged before and/or during the mixing with the synthetic materials. As an alternative, this can also be achieved with the synthetic material and even, for instance, through a continuous stirring within an electric field. The charge remains stable during a long period allowing a previous treatment and a storage of the charge material separated from the mixing operation. A combined loading and mixing reactor, together with an installation (57) for producing a strong grinding of the content, is also part of the invention.
