Title: Rotary compressors
IPC: F04D29/46
Filed: 1963-01-14
Abstract: 957,884. Centrifugal compressors. SULZER FRERES S.A. Jan. 14, 1963 [Jan. 25, 1962], No. 1639/63. Heading F1C. [Also in Division G3] In a rotary compressor of the kind in which the rotor blades have substantially radial inlet edges and the rotor has a semi-axial or radial outlet, or, in the case of a multi-stage compressor, at least the first stage rotor is so formed, surging is prevented by throttling the flow at the rotor inlet by means of a restrictor which adjustably narrows the flow path in a substantially radial direction, thereby limiting the entry cross-section into the rotor at least approximately circularly. In the compressor shown in Fig. 4, the throttling is done by a ring 20 of natural or synthetic rubber which can be inflated from the size shown in the lower half of the figure to that shown in the upper half so as to extend into the intake channel 4. The liquid or gas for inflating the ring 20 is supplied by a pump 25 through a control valve 31. The inflation pressure in pipe 24 acts on the valve 31 in opposition to the force exerted by a spring 30, the spring force being adjustable by means of a hand wheel 32. If the inflation pressure differs from the value determined by the setting of the hand wheel 32, the resultant displacement of the valve 31 connects the pipe 24 either to the pump discharge pipe 28 or to a drain pipe 36 whereby the inflation pressure is brought to that value. The manual control of the valve 31 may be replaced by an automatic control dependent on the compressor delivery. Fig. 2 shows a compressor in which the throttling is done by overlapping segments 7a, 7b which are constrained to move radially by the engagement of slots 9 with guides 10, the radial movement being effected by the engagement of pins 12 in cam slots 13 in a disc 11 which is rotated manually by a worm drive 14. The throttling device may be in the form of an iris diaphragm.

IPC: B41F13/02
Filed: 1940-01-27
Abstract: 538,316. Feeding webs; bronzing &c. BAECHTOLD, H. Jan. 27, 1940, No. 1710. Convention date, Feb. 6, 1939. [Classes 100 (i). and 100 (ii)] In apparatus, for treating the surface of webs, e.g. by printing, embossing, or applying powdered materials to adhesive areas of the web, the web is fed between pressing rollers by a travelling conveyer provided with pivoted clamps holding the web in taut condition both longitudinally and transversely, the drives of the rollers and conveyer being coupled together to ensure accurate registration of the web with the rollers. As applied to a machine for applying finely divided materials, e.g. fibres, metallic powder, glass or sand to areas of a web printed on both sides with an adhesive by rollers 20, 21, bearing relief patterns, the web 1 is fed between the rollers from a braked supply roll 2 by clamps carried by a pair of endless chains 7 diverging outwardly in the direction of movement of the web to stretch the web transversely. The chains, pass round a rear sprocket wheel 10 and a front sprocket wheel 11 which is connected by a chain drive 17 to the, shaft of the roller 20, this shaft and the shaft of the roller 21 being geared together. Adhesive is applied to the rollers 20, 21 by rotating in ducts supplied with excess adhesive from a container' 29 containing an agitator driven from a shaft 13, the excess passing to a reservoir 34 from which it may be forced by compressed air back into the container 29. Adjacent the rollers 20, 21 are a pair of boxes 40, 41, Figs. 1 and 9 provided with rows of nozzles 42 connected by pipes 47, 48 to the supply of fibrous or powdered material and by pipes 49 to a source of compressed air. The material is supplied from a funnel 63 by a pair of rotary fan conveyers 64 driven by an electric motor 66, the material passing through a box 67 to chambers 79, 80 to which the pipes 47, 48 are connected. The box 67 contains compressed air nozzles to agitate the material and bring it to a finely divided condition, and also a number of pivoted dampers by adjusting which the material may be directed to either or both of the chambers 79, 80 or may be directed wholly to a discharge chute 69. The sides of the boxes 40, 41 adjacent the rollers 20, 21 are formed with double walls 43, Fig. 9, forming chambers which are connected by suction pipes 44, 45 to a suction fan 60 to prevent escape of the material from the boxes at the sides adjacent the rollers 20, 21.

Title: Process for treating artificial materials obtained from viscose
IPC: D01F11/02
Filed: 1933-01-18
Abstract: Artificial materials, such as artificial silk, fluff, hair, tow, films, pellicles, ribbons, transparent paper, obtained from cellulose xanthogenate solutions are desulphurized by treatment with a solution of an alkaline sulphite, or sulphurous acid containing a very small quantity of an ammonium base, or an alkali or alkaline-earth carbonate or bicarbonate sufficient to neutralize traces of acids from the coagulating baths which have not been completely removed. Shrinking of the materials during the desulphurizing treatment is avoided.  When alkaline-earth bicarbonates are used the solution may contain an excess of carbon dioxide.  In an example, the desulphurizing solution is made by dissolving 2 parts by weight of crystallized sodium sulphite, and 0.6 parts of sodium carbonate in 100 parts of water.  The treatment may be carried out at ordinary or higher temperatures. It may be applied to filaments continuously with production, or to the material in the form of skeins, cakes, or bobbins.
