Title: Improvements in or relating to wool scouring and recovery of by-products therefrom
IPC: D01C3/00
Filed: 1955-02-16
Abstract: Wool is extracted with a solvent and then scoured with an aqueous solution of a non-ionic detergent.  The solvent may be a petroleum fraction, e.g. hexane, and the detergent may be glyceryl monostearate or an ethylene oxide condensate of the formula R(OC2H4)x OH, where R is an organic radical and x may be between 8 and 35.  Octyl cresol and octyl phenol condensation products with ethylene oxide containing 12 to 14 mols of ethylene oxide are mentioned.  The wool may be mechanically treated to remove burrs and other impurities and dried before the solvent extraction.  The fat-containing solvent may be distilled, the fat purified and the recovered solvent re-used. Absorbed solvent carried by the wool may also be removed and re-used. The extracted wool is then washed with the detergent, rinsed in clean water and dried.  The detergent solution from the washing step is filtered and treated with dilute sulphuric acid or gases containing carbon dioxide to precipitate fatty acids, which are removed by filtering or centrifuging, and the fatty acid-free solution is treated successively with anion exchange and cation exchange resins for the removal of inorganic acids and recovery of potassium respectively, the neutral nonionic detergent being recovered and re-used.  The potassium absorbed by the exchange resin is recovered by regenerating the bed by washing with an acid solution.

Abstract: 402,039. Coin-freed drink-dispensing apparatus. KLEIN, M., 11, Neubaugasse, Vienna. Feb. 17, 1932, No. 4732. Void [Abridged as open to inspection under Sect. 91 of the Acts, Feb. 21, 1932]. [Classes 27 and 106 (v).] A number of different liquids are stored in the apparatus. A purchaser selects a certain number of these liquids, two or five according to the value of the coin inserted, to form a drink, the apparatus being controlled by a single selector which becomes locked after the delivery of measured quantities of the predetermined number of liquids. Each delivery device comprises a reservoir 16 feeding a measuring vessel 18 through a float controlled chamber 17, a sight tube being provided. The liquid in the vessel 18 is delivered through a siphon tube 19, the delivery being started by a piston 21 on the core 15 of a solenoid 14. The delivery pipes 19 of all the liquids discharge through a common outlet 5. The insertion of a coin closes the circuit of a source of current 9, the circuit to the solenoid 14 of the particular delivery device chosen being completed through a contact arm 10 and one of a series of contacts 11. The arm 10 is moved to position by a finger actuated selector dial 4 having holes corresponding to the number of liquids stored in the apparatus. The purchaser also actuates a closing switch 13, which forms a stop for his finger. Coin action, weight; coin-discharging mechanism.-A coin inserted in a shoot 3 tilts a counterweighted lever carrying a mercury switch 8 which closes the circuit. The coins are retained in a receptacle 6 on the lever by a hinged bottom 7. Each time the selector 4 is actuated to deliver a liquid a solenoid 23 is energised to advance a ratchet wheel 24 through one tooth. When the full number of liquids is delivered, a pin 25 on the wheel 24, tilts the hinged bottom 7 to discharge the coin and allow the circuit to be broken at the switch 8. A separate coin balance and ratchet wheel is provided according to the number of liquids to be selected and the coin to be used. Indicators.-The number of liquids already delivered in any prepaid selection is indicated by a rack 29 which bears numerals and is advanced step-by-step similarly to a typewriter carriage by a pawl 28, which is actuated by a relay 27 energised at each actuation of the selector disc 4. When the total number of liquids constituting the drink is delivered, the pawl is disengaged from the rack by the return to initial position of the coin lever, and the rack is returned to zero by a spring 30.

Abstract: 763,479. Transformers. ENGLISH ELECTRIC CO., Ltd. Feb. 18, 1955 [Feb. 19, 1954], No. 4945/54. Class 38 (2). An inductive winding comprises a number of single layer discs A, B, C, D so wound from a number of independent conductors 1, 2, 3, 4 forming a number of independent conductive paths through at least part of the winding, that while the conductive paths through the winding comprise equal numbers of turns, the number of turns (thirteen shown) in any one disc is not an integral multiple of the number (four shown) of the conductors. Thus in each disc one or more conductors has more turns than the others. In Fig. 1 conductors 1 and 4 have an extra turn in discs A, B respectively. Pairs of conductors 1, 2 and 3, 4 are connected in parallel to allow smaller conductors to be used and the members of the pairs 1, 3 and 2, 4 are connected in series. The discs are wound in pairs, A being first wound with three turns from four conductors in the order shown by the letters associated with the conductor numbers in Fig. 2. Conductors 2, 3, 4 are then bent down to the level of the next disc so that a further rotation of mandrel 5 results in an extra turn 1d to disc A and three turns 2d, 3d, 4d to disc B. The turns are then rearranged into the order shown in Fig. 3, and the winding continued with conductor 1 brought to the level of disc B. Finally,- the ends of the turns are cut and joined as necessary to form the connections shown in Fig. 1. Specification 587,997 is referred to.

Abstract: 685,852. Electric selective signalling systems. GENERAL ELECTRIC CO., Ltd., and BRYDEN. J. E. Feb. 28, 1951 [Feb. 28, 1950], No. 5122/50. Class 40 (i) [Also in Group XXXVI] Apparatus for signalling in accordance with the phase-difference between two oscillations of the same frequency comprises means for deriving two further oscillations from the one, and comparing them individually with the other in two phase-sensitive circuits whose 'outputs control balanced polarized relays to produce indications or controls in accordance with the combined operations of the relays. The initial phase-difference is established at the transmitter by means of apparatus described in Specification 685,854 [Group XXXV], at 45n degrees, where n is any integer between 0 and 7. At the receiver, one oscillation, the reference signal, is led to a double phase-shifting network 2, so that the signals in the secondaries 12, 13 of two transformers 7, 11 are respectively lagging and leading the reference signal by 45 degrees. These derived signals are compared with the control oscillation introduced, either directly or with a phase-shift, via a transformer 17, by two discriminator circuits 14, 15, the output voltages of the discriminators being dependent on the phase-relationship between the derived oscillations from the reference signal and the control signal, and being used to selectively operate balanced polarized relays 25, 28. Each relay 25, 28 may thus be operated to one of three possible conditions O, + or -, and the contacts controlled by the two relays may thus. be made to give eight possible indications or controls. The polarized relays may be replaced by other electrical devices. Specifications 676,100 and 685,853, [Group XXXV], also are referred to.
