Patent DE-3466258-D1 (DE)
Title: Continuous digester system
Inventor: LAAKSO OLIVER ARMAS
IPC: D21C7/00
Filed: 1984-04-12
Granted: 1987-10-22
Abstract: Comminuted cellulosic fibrous material, such as wood chips, are treated in a continuous digester to produce paper pulp or the like in a manner providing completely uniform treatment of the chips. The chips are introduced in a feed liquid slurry into the top of the digester, with a swirling action, and establish a vertical column in the digester having a substantially horizontal top, with some liquid between the top of the digester and the top of the chips. Below the top of the chips the feed liquor is withdrawn through a first set of withdrawal screens, and recirculated to entrain other chips to feed them to the top of the vessel. At other vertically spaced areas of the digester other screens are provided for withdrawing, cooking, quench, washing, and like liquors, and effecting recirculation thereof. At each screen set a plurality of nozzles are provided circumferentially spaced around the digester, each nozzle cooperating with only a particular radial segment of the screens. Withdrawal of liquid through the nozzles is practiced so that liquid is being withdrawn substantially through only one nozzle at a time, and it is being withdrawn at the same radial segment of the digester at each screen set at any particular point in time, with progressive switching in a circumferential sequence of the nozzles through which liquor is being withdrawn. Thus deliberate channeling of treatment liquors through the chips column is provided.

Title: Femoral rasp
Inventor: KENNA ROBERT VINCENT
IPC: A61F2/36
Filed: 1984-10-16
Granted: 1988-06-30
Abstract: @ A femoral rasp (10) for preparing an intramedullary canal (14) for receiving the stem of a femoral hip prosthesis comprises a body section (12) generally divided into a wide proximal portion (16) and a substantially longer narrow distal portion (18). The body section (12) has a shape that generally corresponds to the stem of a femoral hip prosthesis to be inserted into the prepared cavity (15). A plurality of spaced apart cutting teeth (20) are located on selected portions of the outside surface of the body section (12) for removing cancellous tissue and bone. A smooth surface (22) on the lateral face of the body section (12) at the free end of the distal portion (18) prevents violation of the lateral cortex upon insertion of the body section (12) into the intramedullary canal (14). Removal of the body section (12) and insertion of the hip prosthesis results in a glove fit between the stem of the prosthesis and the cavity (15) formed by the femoral rasp (10).

Title: A solar-energy collector
Inventor: JANSON GOSTA
IPC: F24J2/46
Filed: 1986-01-29
Granted: 1989-02-09
Abstract: A solar-energy collector has an absorber (5, 31) located in the bottom of a box-like casing, which includes a cover plate (1) which is permeable to solar radiation. The casing encloses a dry gas, to thereby avoid condensation in the solar-energy collector. The casing is hermetically sealed and contains a constant quantity of gas. The cover plate is movably suspended in a resilient frame (2, 20) which forms part of the casing and which permits movement of the cover plate in a direction perpendicular to the plane thereof in response to changes in gas temperature. This enables harmful pressure variations to be avoided in the collector, and the cover plate rests, well protected, on an elastically resilient cushion of gas.

Abstract: A fuel injection system for a spark-ignition internal combustion engine in which combustion air is fed through an air flow meter to produce an input force whose strength is proportional to the mass-volume of the air. This input force actuates the valve member of a valve mechanism to whose input is supplied fuel at constant pressure, the valve member being displaced to an extent determined by the strength of the input force. The valve mechanism includes a fuel output chamber in which the pressure of fuel therein is a function of valve member displacement, this pressure being applied as a countervailing force to the valve member to cause it to assume a null-balance position at which the resultant mean fuel pressure yielded by the output chamber is proportional to the mass-volume of the combustion air, thereby attaining optimum fuel-air ratio conditions throughout a broad operating range.

Abstract: An apparatus for continuously producing from liquid and powder ingredients a substantially homogenous mixture and kneading the mixture to form a compact, plastic mass, and for extruding this mass into elongated extrusions. The mixer comprises a mixer housing (1) and mutually separate liquid and powder delivery conduits (18, 19) and a mixture outlet. A wheel assembly (3, 4) is arranged for rotation in the housing (1) on a shaft (5). The liquid delivery conduit (9) opens into a cavity (7) located in the wheel assembly, whereas the powder delivery conduit (18) opens into powder spaces (10) provided in the upper part (3) of the wheel assembly. The cavity (7) communicates with the upper side of the wheel assembly via a circumferentially extending slot or gap (8) which opens out adjacent an edge (11) which extends circumferentially around the slot or gap on the peripheral side thereof. The slot has a substantially frusto-conical configuration with the apex of the cone facing downwards. Extending around the periphery of the mixer housing is a cylindrical shell (15) which is perforated with holes (16) in that part thereof which extends over the housing outlet, the axes of this shell being coaxial with the axes (5) of the mixer wheel. Blades (12) are arranged in the chordal direction in the mixer housing between the circumferentially extending edge (11) and the cylindrical shell (15).

Abstract: A method of forming a textured layer of tin oxide on a vitreous substrate in which the thickness and degree of texture of the layer can be controlled independently of one another. The method comprises the steps of depositing a first film of tin oxide on the substrate by chemical vapor deposition from a first reactant mixture of tin chloride, water, and an alcohol and depositing a second film of tin oxide on the first tin oxide film by chemical vapor deposition from a second reactant mixture of tin chloride and water. Where the substrate is ordinary soda lime glass, it preferably is first coated with a film of silicon dioxide. The method permits deposition of substantially uniform layers of tin oxide in a continuous deposition process.
