Abstract: A pump (10) is disclosed including an integral clutch and including a housing (26) divided into a clutch zone and a pump zone by a dividing wall (58). An input shaft (12) including a clutch spider (16) is rotatably mounted by a ball roller bearing (54) to a clutch end plate (50). An output shaft (14) is rotatably mounted by linear roller bearings (62, 76) to a pump end plate (68) and the dividing wall (58). A disk pack (20) is slideably mounted to the clutch spider (16) and the output shaft (14) and sandwiched by a piston (34) moved by fluid pressure outward relative to a pressure cylinder (36) and against a pressure plate (28) removably connected to the axial end of the output shaft (14). Thus, axial clutch actuation loads are transmitted only through the disk pack (20) and not to any of the bearings (54, 62, 76). The free axially outer end of the output shaft (14) extends through the pump zone and is located in the pump end plate (68). Clutch actuation fluid is communicated without bearings by first and second passages (96) extending from the pressure cylinder (36) and intersecting with an axial bore (94) in the output shaft (14) into which fluid is introduced by rotary union (98) carried by the output shaft (14) and the pump end plate (68).

Title: A method of producing aseptic consumer milk
Inventor: LINDQUIST ANDERS
IPC: A23C9/142
Filed: 1997-06-25
Abstract: The invention relates to a method of producing aseptic consumer milk with a certain fat content by microfiltration. A continuous flow of milk with a certain fat content passes through a microfilter with a membrane having a pore size of 0.05 - 0.2µm. In the microfilter, the milk is divided up into two part flows, a permeate flow and a retentate flow. The retentate flow, which contains fat and the major fraction of the casein, undergoes a high temperature treatment before being remixed with the permeate flow which contains the major fraction of the whey proteins. The mixture is homogenized and packed aseptically.

Abstract: Burner firing method and device are presented where an oxidizing oxygen--fuel burner is fired at an angle to the reducing air-fuel burner flame to reduce overall NOx emissions from high temperature furnaces. The oxidizing oxy-fuel burner stoichiometric equivalence ratio (oxygen/fuel) is maintained in the range of about 1.5 to about 12.5. The reducing air-fuel burner is fired at an equivalence ratio of 0.6 to 1.00 to reduce the availability of oxygen in the flame and reducing NOx emissions.  The oxidizing flame from the oxy-fuel burner is oriented such that the oxidizing flame gas stream intersects the reducing air-fuel flame gas stream at or near the tail section of the air-fuel flame. The inventive methods improve furnace temperature control and thermal efficiency by eliminating some nitrogen and provide an effective burnout of CO and other hydrocarbons using the higher mixing ability of the oxidizing flame combustion products. The simultaneous air-fuel and oxy-fuel burner firing can reduce NOx emissions anywhere from 30% to 70% depending on the air-fuel burner stoichiometric ratio.

Abstract: A tower for cooling a liquid includes an impermeable outer wall, and a flexible, air-permeable inner wall spaced inwardly from the outer wall to define a chamber between the two walls. The air-permeable inner wall has a multiplicity of pores through which air can pass in order to remove deposits from the internal face of the inner wall. A delivery means is provided for injecting air into the chamber between the two walls, and further delivery means injects air into the internal volume within the inner wall, this being the cooling air. A further means sprays the liquid into the internal volume surrounded by the inner wall. To provide pressurized air to the annular chamber, openings are provided in the outer wall, and a plenum external to the outer wall communicates with the openings, so that by injecting air into the plenum, it will automatically pass to the annular chamber, and thence through the pores of the inner wall, in order to clean the inner wall of deposits.

Abstract: An overhead wire having a spiral groove so formed, as to satisfy the relation 1W/h16 where W and h respectively represent the width and depth of the groove, in the outermost layer formed by intertwisting a plurality of segment strands.  The segment strands include thin segment strands and thick segment strands. A  spiral ridge is so formed that the level difference (H) between the outer peripheral surface of the thin segment strands and that of the thick segment strands, the outside diameter (D) of the overhead wire defined by the thin segment strands, and the central angle (.theta.) of the thick segment strands satisfy the relations 0.01()H/D0.1 and 10~.theta.90~. Recesses are provided on one of the sides of each segment strand and projections are provided on the other. The strands are intertwisted by engaging the recesses and projections to form engaging sections. The length of the contact between the recesses and projections of each engaging section is 10 % or less of the length of each engaging section. Thus, the wind resistance, wind noise, etc., of the overhead wire are reduced and the protrusion, lifting, etc., of the intertwisted strands can be prevented.

Abstract: A punching, stamping rivet has a frustrum-shaped rivet head and a shank with a shank groove following thereafter. In order to create a riveted joint between two sheets, the sheets are punched through by the shank.      A groove is subsequently stamped around the shank end in the lower sheet, thus pressing material of the lower sheet into the groove. In order to increase the strength of the riveted joint, the shank groove is concavely constructed, whereby the section of the groove, which section is adjacent the rivet head, extends at an angle with respect to the shank axis, which angle is less than an angle at which the section adjacent the shank end extends with respect to the shank axis.

Abstract: A self-renewing restricted stem cell population has been identified in developing (embryonic day 13.5) spinal cords that can differentiate into multiple neuronal phenotypes, but cannot differentiate into glial phenotypes.  This neuronal-restricted precursor (NRP) expresses highly polysialated or embryonic neural cell adhesion molecule (E-NCAM) and is morphologically distinct from neuroepithelial stem cells (NEP cells) and spinal glial progenitors derived from embryonic day 10.5 spinal cord. NRP cells self renew over multiple passages in the presence of fibroblast growth factor (FGF) and neurotrophin 3 (NT-3) and express a characteristic subset of neuronal epitopes. When cultured in the presence of RA and the absence of FGF, NRP  cells differentiate into GABAergic, glutaminergic, and cholinergic immunoreactive neurons. NRP cells can also be generated from multipotent NEP  cells cultured from embryonic day 10.5 neural tubes. Clonal analysis shows that E-NCAM immunoreactive NRP cells arise from an NEP progenitor cell that generates other restricted CNS precursors. The NEP-derived E-NCAM  immunoreactive cells undergo self renewal in defined medium and differentiate into multiple neuronal phenotypes in mass and clonal culture. Thus, a direct lineal relationship exists between multipotential NEP cells and more restricted neuronal precursor cells present in vivo at embryonic day 13.5 in the spinal cord. Methods for treating neurological diseases are also disclosed.

Abstract: A case flow system consisting essentially of a roller bed arrangement equipped with a plurality of independent wheels disposed in a spaced-apart relationship along a set of steel axles joined to a pair of side rails. A  plurality of inverted generally U-shaped support members extends from the rear to the front of each bed and is located adjacent to the wheels. A set of cross beams are disposed underneath and in contact with the support members so that the load on the bed may be transferred from the support members to the side rails while simultaneously reducing the load on the axles. The improvement in weight distribution is such that bearingless, inexpensive wheels may be used.
