[Class 69 (ii)] [Also in Group IX] A speed regulating mechanism more especially for regulating the speed of the spools in a spinning machine comprises an hydraulic transmission interposed between the driving and the driven shaft and comprising a variable pump and a variable fluid motor fed by the pump, the pump and motor being individually controlled from two different elements moving by and during the operation of the machine in such a manner that a basic variation is imparted to the driven shaft by the control of one of the elements and a cyclic variation by the control of the other element; in the case of a spinning machine, the variable pump is controlled by either the building motion shaft or the ratchet wheel shaft and the variable fluid motor by the other shaft so that the speed of the spools is varied under the combined control from the building motion shaft and ratchet wheel shaft. As shown the spool shaft 11 of a spinning machine is driven from a constant speed motor 12 through hydraulic transmission comprising a variable pump 14 and variable fluid motor 15, the former being controlled by a radially shiftable member 45 actuated by a rod 19 from the ratchet gearing of the building-motion and the latter by a similar member 45' actuated by a rod 20 from the building motion shaft. The hydraulic transmission. is' preferably that described in German Specification 519,686. The ratchet wheel shaft 21 is geared, to a shaft 24 carrying a cam 27 which actuates a pivoted lever 31 linked to the rod 19 and gives the basic variation by performing one complete revolution while the caps are completely built up while the cam 28 on the building motion shaft actuating the rod 20 performs one revolution for each reciprocation of the ring rail and gives the cyclic variation. The lever 31 has a handle 37 by which the cam follower 33 may be moved into engagement with the cam 27 to start the machine; when the follower 33 is moved out of engagement with the cam, the rod 19 is shifted to reduce the feed to The pump to zero and the shaft 11 stops.

Abstract: 530,801. Making leather. ROBESON PROCESS CO. July 3, 1939, No. 19369. Convention date, July 12, 1938. [Class 76] [Also in Group IV] Leather which has been already tanned is impregnated with lignine obtained from woody fibre by solubilizing with alkali, the lignine being then insolubilized in the leather by treatment with an acid solution. Leather fully or partially tanned with vegetable, mineral or "synthetic" tanning substances may be treated with alkaline solutions of lignine which is then precipitated in the fibres by the addition of sulphuric, oxalic, tartaric or other organic acid or acid sodium sulphate. The lignine for use in the process is obtained by adding sulphuric acid to black liquor from the kraft or soda process, heating, filtering and washing the precipitate. The powder so obtained is suspended in water to which just sufficient caustic soda is added to dissolve the lignine and to give a pH of 8 to 9.2. The tanned hides are soaked or agitated in the solution so obtained.

Title: Fluid flow ducts

Abstract: 1418665 Jet propulsion nozzles - variable area ROLLS-ROYCE (1971) Ltd 26 April 1973 [27 April 1972] 19605/72 Heading FIJ The invention relates to fluid-flow ducts having means to vary the cross-sectional flow area of the duct in which at least one member is attached to a wall defining the duct, there being means for changing the shape of the or each member between a convex form and a concave form, the member when in the concave form lying in a recess in the wall; the member is substantially unstretched in both concave and convex forms. The invention is described with reference to the fan duct of a gas turbine ducted fan engine, the duct being defined between an outer casing 12 and a centre-body 13, a series of six recesses or depressions 29 being formed in the surface of the centre-body, each recess having a member 26 secured around the periphery of the recess, each member being made of material so that it is flexible but substantially inelastic, for example fibre-reinforced sheet rubber. The member 26 is secured to the centre-body 13 as shown in Fig. 4, a metal channel section 39 being bonded to the edge of the member and the assembly being secured to the centre-body by bolts 42. For maximum flow area the members lie in the concave position 28 but for minimum flow area the members are moved sequentially to the convex position 27 by applying pressure air to the underside of the members. The flow of pressure air, which may be air bled from an I.P. compressor of the engine, is controlled by means of a spool valve 32 so that the air flows sequentially to the series of members 26 so as to prevent too rapid rate of change of area of the flow duct. The spool valve is in turn controlled by a bellows which is connected to a pitot head so as to be responsive to aircraft forward speed. The fan blades of the ducted fan may be of reversible pitch so as to provide reverse thrust; the area of the fan duct would be increased to maximum area during reverse thrust operation so as to provide maximum air-flow.
