Title: Improvements in and relating to drying devices
IPC: F26B11/04
Filed: 1932-03-18
Abstract: 398,548. Rotary kilns. RONNE, E., 33, Vestergade, Copenhagen. March 18, 1932, No. 8130. [Class 51 (ii).] Raw materials for cement &c. are treated prior to burning in a rotary kiln 1 in a number of planetary drying chambers 2 arranged around the feed end of the kiln, connected so as to rotate with the kiln and acting as ducts for the gases therefrom, means being provided for feeding the raw materials to the drying chambers 2, which are so arranged as to cause the materials to pass therethrough to a conduit 11 leading to an apparatus wherein the materials are subjected to a dressing before burning. The end of the assembly comprising the kiln 1 and planetary tubes 2 is closed by an annular plate 15 and a number of semicircular plates 16. The central opening in the annular plate 15 is closed by means of a stationary disc 17 through which a tube 5 for feeding the material to be burned in the kiln projects. The gases leaving the kiln and the solid material leaving a fixed spout 6 pass on their way to the planetary tubes 2 through a gap between the end of the kiln 1 and the plate 15, the planetary tubes being provided with openings 18, the adjacent edges of which in neighbouring tubes are joined together, to serve as inlets for the material. The solid material and gases leaving the planetary tubes 2 pass into an annular casing 7, which is stationary, and is provided with an outlet 12 for the gases as well as the outlet 11 for the materials. Spouts or deflectors 10 projecting from the planetary chambers 2 through an annular opening 19 in the casing 7 assist in conveying the materials therethrough. An annular plate 20 is fixed to the ends of the planetary chambers 2 and is provided with holes corresponding thereto, through which the gases and materials pass into the chamber 7. Heat-exchanging bodies 13 of fire-resisting material projecting radially into the kiln serve to reduce the temperature of the gases entering the chambers 2, the kiln being also widened at 14 for the same purpose.

Title: Process for the manufacture of curative sera, vaccines and preparations from animal organs
IPC: A61K39/00
Filed: 1935-03-15
Abstract: Curative albuminous preparations suitable for administration by the mouth are obtained from vaccines, specific sera, preparations of animal organs, normal serum, and whey by a process of partial digestion with pepsin.  The original albuminous substance is treated in an incubator with pepsin and hydrochloric acid and the digestion is stopped when a test shows that the liquid gives a negative nitric acid reaction, but still gives a positive biuret reaction.  The mixture is then adjusted to the iso-electric point, the precipitate formed is removed, and if necessary the liquid is filtered and sterilized.  Examples relate to the treatment of tuberculosis serum prepared according to Specification 297,675, [Class 81 (i)], and of cancerous tissue.  It is stated that sera and vaccines retain their specific action, but that serum sickness and anaphylactic shock are avoided.  Non-specific albumens yield tonic and blood-building preparations.  The preparations may be taken mixed with milk. Specifications 12523/09, 225,585, [both in Class 81 (i)], 387,641, and 438,592, also are referred to.

Filed: 1970-02-20
Abstract: 1,273,697. Variable-speed gearing; toothed gearing. FICHTEL & SACHS A.G. 20 Feb., 1970 [21 Feb., 1969], No. 8220/70. Headings F2D and F2Q.  In a wash and spin-drying machine an extruded synthetic plastics ring gear 9 or 34 of a planetary gear is resiliently mounted in a synthetic plastics housing 11 by vibration damping rubber or synthetic plastics blocks 10 (Fig. 4, not shown) located in pockets in the periphery of the ring gear 9 or 34 and in recesses 12 or 36 respectively (Fig. 3) in the housing 11 in which they are axially retained by a circlip 15, the ring gear having a peripheral rib 13 engaging slots 14 in the resilient blocks 10 by which the ring is resiliently axially retained. Single 31 or stepped planets 3, 4 are also of synthetic plastics and the arrangement equalizes gear loads &c. and reduces noise due to production of dimensional variations caused by extruding or moulding the gear elements for cheapness. As shown in Fig. 1, a two-speed gear comprises an input shaft 1 formed with a sun 2 meshing stepped planet pinions 3, 4 in turn meshing the reaction plastics ring gear 9, a step-down drive being obtained for washing from the carrier 6 through a roller ratchet clutch 10 and a shaft 17 mounting a driven pulley 14. For spin-drying, the speed of an electric motor powering the input shaft 1 is increased so that a mass 24 at the end of the input shaft 1 flies centrifugally outwards to engage a clutch drum 19 on the pulley which is then driven directly from the input shaft 1, the roller ratchet clutch 20 overrunning. In Fig. 2, the stepped planets 3, 4 are replaced by single planets 31 engaging the larger ring gears 34 again located by the blocks 10 in an inner part of the housing 11 adjacent the position for the ring gear 9 of the Fig. 1 embodiment whereby a different ratio is obtained. The mounting blocks 10 may alternatively be of cylindrical or strip form.

Title: Improvements in centrifugal pumps
IPC: F04D29/22
Filed: 1948-03-19
Abstract: 637,005. Centrifugal pumps; stuffing-box substitutes. ABBEY, A. (Jonkopings Mekaniska Werkstads Atkiebolag). March 19, 1948, No. 8275. [Classes 110(i) and 122(v)] The pump shaft is sealed at one end by a rotary impeller located in a sealing chamber, a channel for a cooling liquid being adapted to cool the liquid in the sealing chamber: The sealing liquid may be the pumped liquid itself or a separate liquid. When the pump 'is stationary, leakage along the shaft is prevented by a rubber ring 19 which bears against a flange 20. When the pump is started, the suction created by a sealing liquid impeller 7 forces the ring away from the flange. Liquid leaking between surfaces 16, 17 is directed downwards by a flange 18 and is returned by the impeller 7 to a chamber 5. Auxiliary blades 13 prevent leakage into the pump suction chamber 3. Further auxiliary blades may be provided on the upper surface of the impeller 7 to reduce leakage between the surfaces 16, 17. The sealing liquid in the chamber 5 is cooled by water or air which is passed through an annular channel 24 provided with cooling fins. A pipe 21 may have a valve (not shown) which is opened at starting to admit pumped liquid into the chamber 5 to expel air. The valve may, thereafter, be partially closed, so that only sufficient pumped liquid passes to the chamber 5 to make up evaporation losses.

Title: Magnetic devices
IPC: G11C19/08
Filed: 1973-02-21
Abstract: 1415203 Moving domain devices WESTERN ELECTRIC CO Inc 21 Feb 1973 [22 Feb 1972] 8434/73 Heading H3B A bubble domain device of the field access type is surrounded by a propagation channel 13, Fig. 1, which moves domains laterally in response to a magnetic field re-orienting in the plane of the device. As a result spurious domains in the area enclosed by the channel are removed to the area outside the channel where they cannot interact with data domains in the major and minor loops. These spurious domains may be introduced during manufacture of testing; they can be removed during normal operation, or before operation by reducing the bias field so that they "strip out" and become attached to the channel 13 following which they are removed on restoration of the bias. The use of a domain annihilator (not shown) allows spruious domains in the major or minor loops to be removed prior to introducing data domains. A second channel 30 may be provided which keeps the spurious domains between the two channels for annihilation. This is stated to be particularly suited to devices where the propagation field reverses, i.e. from clockwise to anticlockwise. The channels may each comprise three concentric paths of chevron overlays, and the paths may be joined to form a continuous path like a helix. The channels are spaced apart by three domain diameters.
