Title: Blowers
IPC: F04D29/36
Filed: 1968-12-12
Abstract: Blades mounted on a blower rotor hub of varying cross-section can be moved to alternative positions lengthwise of the hub. The blades can thus be moved to positions of different hub diameter on a conical hub to change the characteristics of the blower. The blower has an axial inflow and discharges either axially or radially outwards. In one construction, Figs. 12, 13, 14, a hollow frusto-conical rotor hub 25 has longitudinal slots 26 with a pair of slideways 29 on opposite sides of each slot. Each rotor blade 27 is normal to the hub surface and has a block 31 which can be slid along the slideways 29 to the required position. In addition, the blade can be turned into a desired angular position. A nut 34 is then tightened on a screw-threaded shank 33 to retain the blade in its adjusted longitudinal and angular positions. The slots 26 may be plugged by removable elements. In a modification, Figs. 9, 10, 11 (not shown), each blade (18) extends radially and is fixed to a block (21) without provision for angular adjustment, the block being clamped in the longitudinally adjusted position by a nut on a stud threaded into the block. Where the annular space between the rotor hub and the blower casing is not of constant width, several interchangeable sets of blades corresponding to different widths may be used, or a single set of blades corresponding to the minimum width is used, an extension piece 61, Fig. 3 (not shown) then being added to each blade tip where necessary. To obtain minimum clearance between each blade and the hub despite variations in angular setting and hub diameter, a liner or a profiled element inset in the blade may be provided.

Title: Method and apparatus for concentrating thermo-labile fluids
IPC: B01D3/08
Filed: 1972-07-06
Abstract: A method and apparatus for concentrating thermolabile fluids, particularly biological fluids, which tend to become denatured and to foam when heated to boiling temperatures. In performing the method, a thermo-labile liquid having a volatile component is confined in a container so that when the container and its contents are centrifuged, a substantial liquid-gas interface will be formed. During centrifugation, the pressure within the container is reduced to cause rapid volatilization of the volatile component at a temperature well below the denaturization temperature of the liquid. Centrifugation is performed at a speed sufficient to substantially eliminate foaming of the liquid during such volatilization. Moderate heating of the container and its contents to promote such volatilization may be provided. The centrifuging, gasevacuating, and heating steps are all performed simultaneously and are continued until the concentration of the liquid has been increased a predetermined extent.

Title: Hexetidine salts
IPC: A61P31/04
Filed: 1976-11-05
Abstract: There is described a process for the preparation of novel salts of hexetidine with aromatic carboxylic acids of the formula II < IMAGE > in which n denotes 1 or 2 and if n = 1 the substituent X is -COOH, -OH, -NH2, -SO3H or -SO2NH2 with the proviso that X is present as -COOH or -OH in the 4-position, and if n = 2 X has the prior meaning with the proviso that different X radicals are present. The base is reacted with the said acid in a solvent and the salt is obtained by crystallising out. The salts prepared are distinguished by poor solublity in organic solvents and can therefore easily be separated off from accompanying by-products. Pure hexetidine can also be obtained from the resulting salts by reactions with an aqueous base. Since both the salts and the pure hexetidine have antimicrobial activity, they are used in particular as an antiseptic for the oral mucosal membrane.
