Title: Improvements in or relating to devices for delivering fluids under pressure
IPC: F04C14/26
Filed: 1927-05-16
Abstract: 300,593. Vickers, Ltd., and Pool, W. May 16, 1927. Governing and regulating.-A valve device for use in connection with metering pumps used in apparatus supplying cellulose acetate or other cellulose solution to extruding heads for the formation of artificial silk threads comprises a piston valve controlling a supply under pressure and actuated by a piston subject to the pressures in the conduits leading to and from a pump-like element preferably of the gear type and adapted to open further the inlet when the outlet pressure increases so as to restore the balance of pressure. The piston valve B has three bands b<2>, b<3>, b', the bands b<2>, b<3> being provided with apertures b<x> for the passage of fluid, The pressures in the conduits A', A<2> leading to and from the gear pump A which is driven by wheels a, a<x> act on the valve so that under normal conditions the band b<2> leaves the inlet port for high pressure fluid slightly open. If the outlet pressure rises the inlet is opened wider and if it falls the inlet is further reduced. In the event of the outlet pressure exceeding the pressure in the conduit B<2x>, the valve rises so that the band b<3> closes the inlet and the band b<4> passes above an annular groove b<1x> to short circuit the gear pump. Reference has been directed by the Comptroller to Specification 293,325.
Patent GB-641242-A (GB)
Title: Improvements in cellulose products
IPC: C08B1/00
Filed: 1947-05-15
Abstract: A water-soluble manganese compound is added to cellulose for conversion into viscose in an amount corresponding to 1-100 parts per million Mn by weight based on the bonedry weight of the cellulose. The manganese accelerates the alkaline oxidation of the cellulose, and thus permits a higher viscosity cellulose to be used in the first place for conversion into viscose.  The manganese is preferably added in amounts from 4-20 p.p.m. giving a total manganese content (including that originally present in the pulp) of 4-25 p.p.m.  It may be added as an inorganic compound such as manganous sulphate or nitrate, or if desired, as potassium permanganate, or organic compounds such as the acetate may be used.  By addition of a compound such as manganese oleate the effect of the manganese is obtained in addition to the known effect of the addition of surface-active compounds.  If desired, the manganese compound may be dissolved in the wash water used in the pulp preparation, or it may be applied by dipping the pulp sheet into a dilute solution of the salt or by spraying the liquid containing the manganese compound on to the pulp sheet, preferably as it passes into the dryer on the pulp machine. It is important to maintain the manganese content uniform.  In an example a web of refined wood pulp (degree of polymerization 690) containing 0.1 p.p.m. "natural" manganese was sprayed uniformly with a dilute solution of manganous sulphate in amount sufficient to add 5 p.p.m. manganese based on bone dry pulp.  It was converted to alkali cellulose, aged for 10 hours at 30 DEG  C. and xanthated to give a viscose of viscosity 35 sec. (D.P. 300).  Identical pulp but without the addition of manganese and processed to give viscose required 24 hours ageing to give the same viscose viscosity.  The Specification as open to inspection under Sect. 91 refers to the use of manganous phosphate or carbonate and manganese dioxide or hydroxide.  This subject-matter does not appear in the Specification as accepted.

Title: A textile ring twisting machine
IPC: D01H1/36
Filed: 1960-04-19
Abstract: 930,824. Doffing and donning in ring spinning machines. ALGEMENE KUNSTZIJDE UNIE N.V. April 19, 1960 [April 17, 1959], No. 13694/60. Class 120 (2). In a ring twisting machine in which the ring rail 1 together with its rings 2 are normally traversed by the movement of a builder cam 26 revolving about a shaft 27, the linkage being a cam follower 25 on a pivoted arm 17, a chain 15, a crank 9, 11, a roller 7 and a push rod 5, a further cam 28 is provided which, as shown in Fig. 2, may override the influence of cam 26 and move the ring rail beyond its normal range of traversing. Cam 28 in its rest position has its shortest radius towards its associated follower 24, all the radii of cam 26 being greater than this so that builder cam 26 may normally continuously contact its follower 25. When the cap tubes on the spindles are full, a motor 33 is manually switched on to rotate cam 28 in an anticlockwise direction. After about one third of a revolution cam 28 having engaged its follower 24 and lifted arm 17 out of engagement with builder cam 26, has pushed arm 17 and therefore the ring rail 1 to their lowest positions and at this point cam 28 is automatically stopped. The rings 2 are now in line with auxiliary surfaces in the spindles on to which the yarn is wound for a few moments until the whole machine is manually switched off. The full tubes are then doffed and empty ones donned, the yarn remaining threaded to the auxiliary surface. The whole machine and the motor 33 are then started. Because of the shape of cam 28, the rings 2 first move away from the auxiliary winding surface; they then pause to wind transfer tail on the tubes; finally they rise until builder cam 26 contacts its follower 25 and normal traversing is resumed. Cam 28 now out of contact with follower 24 continues to rotate until its shortest radius is again towards its follower; motor 33 is then automatically switched off. For disturbances such as thread breakage the ring 2 at the associated spindle may be disconnected from the ring rail 1 and lowered on a guide 4 to a position adjacent its auxiliary winding surface so as to be re-threaded. The described machine may follow some other processing such as the stretching of artificial fibres.

Abstract: 1383957 Hot-pressing powder mixtures CENTRE NATIONAL D'ETUDES SPATIALES 23 March 1972 [30 June 1971] 13757/72 Heading C7D [Also in Division H1] A method of making an electrode comprises the steps of preparing a powder mixture of a powdery compound forming the electro-chemically active material of the electrode or capable of forming it by chemical or electro-chemical reaction, and of a metal powder forming the conductive support material of the electrode, and hot pressing the powder mixture in an atmosphere to which the mixture is inert, to produce an electrode of the desired shape by sintering the conductive support material without chemical transformation or volatilization of the powdery compound. The material comprising the powdery compound is chosen to have a melting point and temperature of decomposition well above the sintering temperature of the metal powder forming the conductive support material. Depending on the materials constituting the powder mixture the sintering is carried out over a range between 300 and 700‹C at a pressure between 100 and 2000 Kg/cm<SP>2</SP>. Examples of powder mixtures are as follows, the first powder constituting the support and the second powder constituting the active material:- (i) nickel, nickel fluoride, (ii) as (i) but with small proportion of cobalt fluoride, (iii) nickel, cadmium fluoride, (iv) as (iii) but with small proportion of Fe 2 O 3 , (v) and (iii) but cadmium fluoride replaced by KCdF 3 , (vi) Ag, KCdF 3  with small proportion of TiO 2 , (vii) Ag, Ag 2 SO 4 , (viii) Zn, ZnO, with small proportion of mercury oxide and ammonium chloride, (ix) as (viii) but ZnO replaced by Zn 3  (PO 4 ) 2 , (x) Cu, CuF 2 , (xi) Ag, HgO. The sintered electrode, for example, as in (i) may then be immersed in 6N-KOH and the NiF 2  converted to Ni(OH) 2 . The electrode is then formed by a series of charging and discharging cycles in an alkaline electrolyte to produce NiOOH. A bi-polar electrode is described having one side as (iv) and the other side as (ii). A metal grid may be incorporated in the powder mixture before the sintering step and a plastics binder may also be incorporated to avoid the use of a mould, and in this instance the mixture may be dissolved in a volatile solvent and applied by a spray gun to the grid. Examples (x) and (xi) are intended for use as cathodes in primary cells and the subsequent chemical treatment is omitted.
