Title: Improvements in or relating to the treatment of textile fibres
IPC: D06M15/11
Filed: 1933-12-02
Abstract: Textile fibres are sized preparatory to weaving &c. by forming on the fibres a protective colloid layer which contains no resinifying and/or oxidizing constituents, then applying the actual sizing layer which usually contains such constituents, the fibres being finally desized after treatment.  The protective colloid layer may be a thin vegetable mucilage, or agents such as tragacanth, gelatine, colloidal starch &c.  The sizing layer proper may be of the usual kind or a varnish or lacquer insoluble in water prepared by mixing linseed oil varnish, turpentine, a solvent, e.g. benzine-benzol, resin and highly sulphonated oil. The protected fibres are treated with such a solution, centrifuged, dried and exposed to air to effect oxidation. The desizing is carried out in a soap bath of not above 5 per cent strength with addition of swelling agents or solvents.

Patent GB-970945-A (GB)
Title: Process for neutralising acidic acetone-phenol mixtures
IPC: C07C37/08
Filed: 1961-09-22
Abstract: Solutions containing at least 25% by weight of cumene peroxide obtained from the acid hydrolysis of cumene hydroperoxide in admixture with cumene, and possibly side products of the oxidation of cumene by air or molecular oxygen, are neutralised by passing over an anion exchange resin, preferably phenolic-base resins having a secondary amino or tertiary amino functional group. A fixed bed of resin in a column is employed. The resin is first brought to its hydroxyl state by washing with dilute NaOH, and then with distilled water, to remove excess NaOH. When the water retained by the resin has been fully displaced by acetone the supply of acidic hydrolysate is started, and stopped when the resin is spent. The residual partly neutralised hydrolysate in the resin is displaced by acetone and added to the acidic hydrolysate to be neutralised in the next run. Upon completion of this displacement, the acetone is displaced in turn by distilled water and the resin then regenerated using NaOH solution.  The cycle can then be repeated. In modifications of the process, after regenerating the resin with NaOH and washing with water, instead of displacing the water with acetone, the water is discharged by draining. Water absorbed by the resin is removed with warm air and the supply of acid hydrolysate then started.  Upon completion of the cycle, instead of displacing the partly neutralised hydrolysate with acetone, the mixture is drained from the resin with the assistance of compressed air. The resin is then washed by flooding it from the bottom with acetone and subsequently water. Washing with water and regeneration are carried out as before. In examples "Duolite" A7 and A2 resins (Registered Trade Marks) are utilised in the process and its modifications to neutralise a phenol/acetone mixture containing about 22% of a mixture of cumene and side-products and 0.2% sulphuric acid.

Title: Improvements in and relating to electric motor speed regulating systems
IPC: H02P7/30
Filed: 1930-11-12
Abstract: 361,107. Maintaining defined speeds of motors; centrifugal switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Merrill, F. W.; 1134, Oakdale Drive, Fort Wayne, Indiana, U.S.A.) Nov. 12, 1930, No. 34089. Convention date, Nov. 12, 1929. [Classes 38 (iii) and 38 (v).] The speed of an alternating current motor, used for example in talking-picture systems, is maintained constant by means of a speed responsive switch which opens on decrease of speed and closes on increase of speed, to vary the current in one of two opposing direct current windings of a reactance so as to vary its impedance. When a switch 19 is moved to the right a compensated repulsion motor 23 is energized from mains 20 through a reactance 21. The motor drives a centrifugal switch 26, which at the desired speed closes its contacts to short-circuit part of a resistance 30 in the circuit of a direct current winding 31 on the reactance 21. The winding 31 opposes a second direct current winding 29 so that the removal of resistance from the circuit of the winding 31 increases the impedance of the reactance, and the motor speed falls. Thus the switch 26 opens, the impedance is again decreased, and the cycle is repeated. The speed at which the motor is maintained may be adjusted by means of a screw on the switch 26, and the range of speeds over which the regulator works is selected by means of a switch 27. When the switch 19 is moved to the left the motor circuit is broken and the motor is braked to rest. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement in which the reactance has only one direct current winding and in which the centrifugal switch opens its contacts on increase of speed, and also an arrangement in which a centrifugal switch controls a resistance in the field circuit of a direct current motor. This subject-matter does not appear in the Specification as accepted.

Abstract: 996,112. Gas turbine engines. ROLLS-ROYCE Ltd. Sept. 2, 1963, No. 34650/63. Heading F1G. [Also in Division F2] In a means for supplying lubricant to the bearing immediately rotation takes place and to ensure that a quantity of lubricant is retained so that the bearing can be lubricated during its period of rotation, the bearing is first freely supplied with lubricant through an aperture or apertures and then gradually supplied with lubricant through a selected aperture or apertures. In an embodiment, a gas turbine vertical lift engine 10 comprises a compressor 11, combustion equipment 12 and a turbine 13, the compressor and turbine being mounted on a shaft 15 which is supported by a ball bearing 16. An annular lubricant chamber 31 has an inner wall 32, an outer wall 33 and a base 34 and has a compartment 35 with a central portion 36 which communicates with an inlet duct 37 connected to a pump 40. The chamber 31 has also two portions 41 which are separated from the portion 36 by weirs 42; has compartments 43-46 which are formed by radial wall members 47; each wall 47 having an aperture 50 therein; and has a large compartment 51 positioned intermediate two compartments 46. The central portion 36 has in its base 34 two apertures 52 and each of the two compartments 46 has in its base 34 an aperture 53, the apertures 52, 53 allowing lubricant to flow to the bearing 16. The compartment 35 and portions 41 are covered by a plate 54 and a vent 55 is provided between the plate 54, and the inner wall 32 of the central portions 36, so that lubricant may be passed to, an annular space 56 which is formed between the inner wall 32 and the shaft 15. The annular space 56 is connected to the compartment 51 by apertures 60 in the wall 32 and lubricant is passed to the bearing 16 through apertures 61 in the base 34 of the compartment 51. In operation, the pump forces a single shot of lubricant through the duct 37 and into the central portion 36. A small proportion of the lubricant is retained in the portion 36 by the weirs 42 and is passed to the bearing 16 via the apertures 52 in the base 34. The greater part of the shot enters the portions 41 and passes through the apertures 50 in the walls 47, through compartments 43-45 and into the two compartments 46, from where it passes to the bearing 16 via apertures 53. If more than one shot of lubricant is inadvertently delivered to the portion 36, the excess lubricant is passed through the vent 55 and into the annular space 56, from where it is gradually fed to the bearing through the apertures 60, 61.
