Title: Improvements relating to the preparation of staple fibres, obtained from continuous filaments for treatment subsequent to the cutting operation
Filed: 1953-04-20
Abstract: In the manufacture of staple fibres by cutting a continuous filament cable, the latter is soaked with a solution which will evolve gas upon heating or by reaction with an acid before it is cut into staple lengths, the staple fibres being then dropped into a washing liquid which contains an acid or is heated so as to evolve the gas, whereby the fibres are separated from one another during the washing treatment.  The solutions may be of alkali metal carbonates or bicarbonates or of substances which liberate nitrogen on heating, and the washing liquid may be heated to 80-90 DEG  C. or may contain acetic, sulphuric or hydrochloric acid. Carbon dioxide or other inert gas may be passed through the liquid from below to assist the disentanglement of the fibres.

Title: Method of and apparatus for the continuous measurement, recording or regulation of viscosity by a capillary viscometer
IPC: G01N11/08
Filed: 1955-04-15
Abstract: 768,610. Viscosimeters. LIEB, O. April 15, 1955 [April 17, 1954], No. 10948/55. Class 106(2). A viscosimeter comprises a first vessel 2 in which a constant head of liquid is maintained and which discharges by a comparatively wide tube into a second vessel 4 having a restricted discharge orifice in the form of a long capillary tube 7 so that the reduction in flow causes the liquid level in the vessel 4 to rise in accordance with its viscosity. The head H of liquid may be measured directly by the gauge tube 10 or manometrically by an air or gas line 11. The overflowing liquid from the constant level vessel 2 is circulated through a jacket 6 to provide a temperature control. Vents 9, 13 permit adjustment to atmospheric or any other selected pressure.

Patent GB-643552-A (GB)
Title: Improvements relating to rotational viscometers
IPC: G01N11/14
Filed: 1948-04-21
Abstract: 643,552. Viscosimeters. DOBBIE McINNES, Ltd., and BOYLE, A. R. April 21, 1948, Nos. 10973/48 and 484/49. [Class 106 (ii)] The viscosity of a liquid is measured by measuring the input current to the direct phase 13 of a squirrel-cage induction motor driving a body rotating in the liquid under test. The motor is provided with two stator windings with electrically 90 degrees phase difference b tween them, one winding 13 being connected directly across the supply transformer 17, the other winding 12 having a condenser 14 in series, the reactance being such as to cause resonance in this phase at approximately synchronous speed. Fig. 9 shows the relationship between the current in the direct phase ABS and the condenser phase MTU. Since these curves are almost complementary, the total current taken by both phases remains approximately the same over the working range. In order to obtain a sensitive measure of the input current, measurement is made by a milliammeter 15 in circuit with the direct phase alone. The portion AB of the curve ABS represents the working range and is substantially straight and independent of variation of supply voltage. One embodiment of the invention is shown diagrammatically in Fig. 2, where liquid enters via a channel 20 in a body 17 and leaves via a channel 21. A portion of the liquid is diverted through a channel 22 and flows between the stator 18 and rotor 19 in the passage 24. An alternative embodiment is shown in Fig. 5 in which the rotor shaft is extended outside the stator by a shaft 31 to drive a cylinder 32 which is immersed in the fluid to be tested, the motor being supported on a guide rod 30. A further modification is shown in Fig. 7 in which the cylinder 41 is enclosed by a sleeve 42 which may be interchangeable to vary the clearance between the two, for liquids of different viscosity. In this example the motor is raised or lowered by operation of a handle 40, the liquid to be tested being contained in a vessel 44. The range of the apparatus may be varied by altering the mechanical or electrical characteristics thereof, for example, the gap width at the rotational body, the length of rotor and stator, or the diameter of the rotor, also the number of stator poles. Alternatively, variable gearing may be provided between the motor shaft and the rotational body, as the viscosity reading is then approximately proportional to the square of the gear ratio, ratios of 1: 1, 10: 1 or 100: 1 are employed.

Title: Turbine stator blade rings
Inventor: GILBERT RONALD ALBERT
IPC: F01D17/16
Filed: 1957-04-04
Abstract: 839,697. Elastic fluid turbines. NAPIER & SON Ltd., D. June 4, 1958 [April 4, 1957], No. 10990/57. Class 110 (3). In a turbine stator blade ring in which the blades are pivoted about axes substantially radial to the turbine axis and a part of each blade makes a close fit with a fixed locking part, means are provided for delivering fluid, at a temperature different from that of the gases passing through the blade ring, into close thermal contact with the closely fitting parts to cause differential thermal expansion between them to lock them or free them for relative movement. The closely fitting part of each blade may be the blade proper or another part such as the blade root or blade spigots. A locking ring 20 (Fig. 1) closely fits the inner edge of each blade proper 10 and comprises two inwardly directed flanges 22, 23 which make sliding contact with the walls of an annular groove in a frame member 14 to form an annular chamber 24. At the operating temperature of the turbine the ring 20 locks the blades, but when cooling air, e.g. from the turbine compressor, is admitted to the chamber 24 the ring contracts and frees the blades which may then be rotated by an operating ring 16. For automatic operation a floating lever 38 (Fig. 2) is connected to the ring 16 and to the control rod 28 of a piston 27 spring-biased to a central position in a valve cylinder 26 where it closes a cooling-air entry port 31. Movement of a manual operating lever 39 in either direction displaces the piston 27 and admits air to the chamber 24 through a duct 34. When the locking ring has contracted the piston 27 is free to return to its central position and rocks the lever 38 which adjusts the blades. The air supply to the chamber 24 then ceases as the port 31 is closed and the ring 20 expands again to lock the blades in their new position of adjustment.

Patent GB-340900-A (GB)
Title: Improvements in or relating to devices for cutting the cables of submarine mines
IPC: B63G7/04
Filed: 1930-04-10
Abstract: 340,900. Submarine mines. SOLKESZ, J. H., Oedjong, Sourabaia, Java, Dutch East Indies. April 10, 1930, No. 11408. Convention date, April 11, 1929. [Class 9 (ii).] A device for cutting the mooring cables of submarine mines comprises a gripper which prevents slipping of the cable during the cutting operation. The device comprises a cylinder 2, Figs. 1, 2, containing a piston 1 which is actuated by a spring 4. The piston has a vertical slot a in which is pivotally mounted, about trunnions m, a clamp k. The trunnions are journalled in blocks which slide in grooves d in the side walls of the slot a and which are normally held in the uppermost position by springs n. The lower side of the piston is flat and has screwed thereto a slotted plate f, Fig. 1,which is disposed adjacent to a knife s. Two such devices are provided on a vessel and are connected bv a wire rope, as partly shown in plan in Fig. 7. In operation, the mooring cable of the mine is caught and carried along the rope and is led, by a guidearm 3, into the slot a, and bears against the clamp k. The slipping of the cable past a roughened surface p of the clamp produces a downward movement thereof, while an anticlockwise rotation (see Fig. 1) is imparted thereto, as the vessel moves, by that part of the cable connected to the mine anchor. These two movements of the clamp bring the surface p thereof close to a roughened surface b of the slot a, and the cable is firmly gripped. The inclination of that part of the cable below the device moves the piston 1 rearwards in the cylinder 2 against the action of the spring 4. The knife 8 cuts the cable and releases the pressure on the piston and clamp. The mine is thus freed and the parts then return to their normal positions.
