Patent JP-H0667513-B2 (JP)
IPC: B01F3/04
Filed: 1989-06-02
Abstract: In aeration devices for introducing gas into a liquid, there is the problem of the introduction body filled with gas being subjected to buoyancy. To eliminate this buoyancy, the introduction body is formed to be open at its free end and to be closed at its other end where it carries a fixing branch by means of which it can be connected to a gas supply distributor. The introduction body is surrounded by a perforated tubular membrane and a gas feed channel ends in the region of the membrane. 
<??>To facilitate manufacture and assembly and to reduce the consumption of material, the introduction body is designed such that its gas feed channel passes through the fixing branch as a bore which is axially blind and that at least one radial outlet is present in the region of the membrane. Preferably, a longitudinal groove which allows uniform distribution of the gas extends from the outlet of the gas feed channel to a point in front of the free end of the introduction body.

Abstract: Sample analysis in a portable analytical instrument (100), preferably in the form of a gas chromatograph, benefits from temperature control of one or more thermal zones (108) in the instrument by way of a thermal isolation system (104) that includes a novel pumping assembly (124) to effect a selective amount of thermal isolation of the thermal zone. The pumping assembly includes a pumping element (210) in the form of a tubular or planar palladium structure (502). The pumping assembly (124) makes use of the unique properties of palladium to allow selective control of a nominal gas pressure within a vacuum cavity. A component system (106), which may include a separation column (318) and a thermal device (118) for heating and/or cooling the component system, may be provided within the vacuum cavity. The thermal device (118) and the pumping assembly are individually controlled by a control system (102). The pumping assembly (124) may be operated to allow selective control of the thermal isolation of the thermal zone; alternatively, the component system (106) may be subject to a controlled temperature by operating the thermal device. A sample mixture passing through the separation column (318) may thereby be exposed to a desired temperature profile according to a selected program so that the sample will separate into its components for subsequent detection by a detector (321). <IMAGE>

IPC: F01D17/16
Filed: 1987-07-02
Abstract: An adjusting mechanism for pivotal guide blades of turbo-propulsion units in which a rotatable adjusting ring is supported in a concentric support ring. The support ring is heat-insulatingly connected with the turbine housing by way of several connecting lugs or slide block guidances distributed over the circumference and the adjusting ring is connected with the guide blades by way of bendable pivot levers. It is achieved thereby that the heat flow from the hot turbine housing to the adjusting mechanism remains small and an exact adjustment of the guide blades can be achieved in this manner.

Abstract: PROBLEM TO BE SOLVED: To solve a problem that a sealing section 3 of a liquid crystal display device 1 has the strength resistant to an external force inferior to that of other parts and the sealing section 3 tends to be often damaged because the sealing section 3 has been placed at a place to which the external force exerted from a front case 10 is comparatively often delivered depending on the configuration of a portable information terminal when the sealing section 3 is mounted on the portable information terminal. SOLUTION: The sealing section 3 of the liquid crystal display device 1 is placed in the vicinity of a battery pack 24 mounted on a rear case 16 of the portable information terminal and the rigidity of the battery pack 24 suppresses propagation of the external force from the front case 10 so as to protect the sealing section 3 from being damaged. Furthermore, ribs 10a, 23a acting like reinforcement members are placed in the vicinity of the sealing section 3 to suppress the external force coming from the front case 10 from delivering to the vicinity of the sealing section 3.

Abstract: The web embossing machine of the present invention has two embossing cylinders (3, 5) brought close to one another for combining two paper webs (N3, N5) by the pressure contact between mutually corresponding protrusions (S) on the two cylindrical surfaces. The protrusions are in rows which present a pattern inclined relative to the axes (X-X) of the respective cylindrical surfaces, i.e., in a helicoidal fashion and relative to a plane passing at right angle through said axis, and thus achieve a subsequent and progressive contact instead of a simultaneous contact throughout the row. The inclination relative to a plane passing at right angle through the cylinder axis avoids repetitive pressure actions on the pressure rollers cooperating with the embossing cylinders.

Abstract: A particulate proteinaceous product is prepared from waste raw protein-containing animal parts with a method and an apparatus having a mulling stage wherein the raw animal parts are reduced to a ground condition; a hydrolyzing stage wherein proteins in the ground animal parts are hydrolyzed to a predetermined extent to form an aqueous suspension, using either endogenous or supplementary proteolytic enzymes, and subsequently heated to inactivate the enzymes and convert fats in the suspension to oils; a screening stage wherein non-digestible solids are removed from the suspension; a concentration stage wherein extraneous oil is added to the suspension, the suspension is pasteurized, and a large portion of the water is removed therefrom; and an oil-separation stage wherein sufficient oil is removed to form the product. A portion of the removed oil is routed back to the beginning of the concentration stage as extraneous oil added to the suspension to permit sufficient water to be removed from the suspension without forming a stiff, unprocessable mass. The method is distinctive in that it produces a dry, flaky product without the use of a conventional dryer. The method is also distinctive for its substantial resistance to equipment clogging. The proteinaceous product is dry to the touch, is compressible into pellets or cakes, and contains about 45 to 65 w/w percent partially hydrolyzed, non-denatured animal protein, about 20 to 35 w/w percent oil derived from the animal parts, about 10 to 15 w/w percent moisture, and about 0 to 7 w/w percent ash. The product also has reduced objectionable odor, reduced propensity to oxidize, and high nutritional value.
