Abstract: 1,184,890. Hello-centrifugal and axial-flow blowers. P. BERRY. Dec. 10, 1968 [Dec.12, 1967], No. 58712/68. Heading F1C. 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 6<SP>1</SP>, 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.

Abstract: 1370318 Preparation of 6-methylenetetracyclines RACHELLE LABORATORIES ITALIA SpA 21 Dec 1971 [28 Dec 1970 26 Oct 1971] 59247/71 Heading C2A A process for the preparation of a 6-methylenetetracycline comprises halogenating a tetracycline base or an acid salt thereof in solution at sub-ambient temperatures while maintaining the pH of the reaction mixture at from 3À0 to 5À0 to spontaneously crystallize the 11a-halo-6,12- hemiketal substantially entirely in the enolic form. Then the 11a-halo-6,12-hemiketal base is converted to the corresponding acid salt, e.g. the perchlorate, this salt is dehydrated to the corresponding 11a-halo-6-methylene tetracycline and this is dehalogenated to provide the desired 6-methylene tetracycline. The hemiketal base may be treated with acid at a temperature from -10 C. to 20 C. in order to convert it to the corresponding acid salt. The 6-methylene tetracyclines which may be prepared include 6- methylene-5-oxytetracycline, for which the initial tetracycline reactant is 5-oxytetracycline. The 11a-halo-6-methylenetetracycline may be dehalogenated to form an acid salt of the 6- methylene tetracycline and the acid salt converted to the free base of the desired 6-methylenetetracycline by neutralizing it at a temperature of from 50 C. to 90 C. in an aqueous solution maintained at a pH of from 6À5 to 7À5. The 11a-halo-6,12-hemiketal base may be formed by halogenating the tetracycline base or acid salt thereof in solution at a temperature below 0 C. and at a pH of from 3À5 to 5À0.

Filed: 1970-12-31
Abstract: 1287020 Coated glass-fibre-forming apparatus OWENS CORNING FIBERGLAS CORP 31 Dec 1970 62020/70 Heading B2E [Also in Division C1M] Glass fibre forming apparatus comprises a bushing fabricated from a precious metal alloy having side walls and bottom wall and a plurality of tubular projections extending downwardly from the bottom wall for emitting a plurality of streams of molten glass attenuated into glass filaments, and a refractory material removably bonded to the side walls and to the bottom wall of the bushing at a density sufficient to retain and prevent outward migrations of metal oxide that volatilise from the alloy when in use at high temperatures, while at the same time providing support to the alloy. The bushing may be produced by covering the surface of the projections, applying a coating of the refractory material to the uncovered surfaces of the wall and removing the covering. The surface areas of the wall may be roughened prior to applying the coating of refractory material, the area immediately adjacent each projection being masked prior to the roughening operation, e.g. by grit blasting. The projections may be protected during grit blasting and application of the refractory coating by covering with hard metal alloy covers which are removably fixed to the projections, e.g. a cover of stainless steel or by dipping the projections into an organic material, e.g. polyamides, polyurethanes and silicone-base resins with dispersed alumina or other refractory material. The refractory material may be applied by plasma spray or flame spraying and may be magnesium zirconate. The projections may be arranged in spaced apart double rows. As shown in Fig. 4, a bushing 40 is coated with refractory material 42 which is easily removed after service at high temperatures and a high temperature resilient fibrous material 44 lies adjacent the refractory coating and serves as an insulation and cushioning means. A disposable castable refractory material 46 surrounds the fibrous material on the side walls adding support and insulation to the side walls during operation of the apparatus at high operating temperatures. The inside of the bushing may also be coated with refractory material. After service the castable refractory material can be thrown away and the refractory coating stripped with an acid from the bushing and precious metals separated therefrom by gravity, ion exchange and filtration. Alternatively the refractory material may be stripped from the bushing by blasting with glass beads and then dissolved in acid for further separation.

Title: Drying tea
IPC: F26B21/06
Filed: 1978-07-12
Abstract: A tea drier in which tea to be dried enters at point G and travels leftwards along band 8, then rightwards along band 9 and exits at H whilst hot air from a fan 3 and heater 4 is blown over the tea and exhausted via ducts 6 and 7. The exhaust air entering duct 7 is exhausted to atmosphere, but that entering duct 6 is recycled and passed back over the tea via duct 14. The condition of the recycled air is adjusted in various ways in dependence upon the humidity of the exhaust air passing into duct 6: in Figure 1, the quantity of air which is recycled is controlled in dependence upon the humidity of the exhaust air in duct 6; in other embodiments, the temperature and the humidity of the recycled air are controlled. This control of the recycled air allows greater heating efficiency to be obtained and enables any deleterious effect on the taste of the final product to be avoided. <IMAGE>
