Title: Improvements in cyclone dust separators
IPC: B04C3/00
Filed: 1938-02-25
Abstract: 491,431. Centrifugal dust - separators. REEVES, H. C. Feb. 25, 1938, No. 5970. [Class 23] A cyclone dust-separator has a convergentdivergent separating chamber with a dust discharge opening located beyond the divergent portion. The tube a forms the separating chamber and has a convergent part c and a divergent part d. The entering gas is caused to whirl by the vanes b. The dust is thrown to the periphery by the time the stream reaches the end of the part d and is then skimmed from the main stream by annular openings e, f, g formed between tubes h, i, j of decreasing diameters. The dust passes through these openings into a closed collecting chamber k with a discharge valve l. A nozzle m is fixed at the end of the tube j and projects through an opening n in the wall of the chamber k into a diverging outlet tube o which acts as a diffuser. This arrangement causes gas to pass from the chamber k through the opening n to reduce pressure in the chamber and so assist the dust to pass through the skimming openings. A filter partition p may be arranged in the chamber k before the outlet n, and it may be used to support the tubes i, j ; the latter tube j may be flexibly supported and the filter will then be vibrated sufficiently to shake off dust.

Title: Improvements in and relating to a method and apparatus for producing shorn twisted textile yarn
Inventor: HILL MOORE
IPC: D01H1/10
Filed: 1963-02-14
Abstract: Shorn twisted yarn is made by twisting the yarn in a 2:1 twister of the outflow type and then bringing the twisted yarn into contact with a shearing or cutting head before it is spooled or wound up.  When the twister has a single flyer the yarn is led to the shearing head without changing direction on leaving the eye defining the apex of the balloon.  When the twisting means has two flyers and carries two yarn packages, it may take the form described in Specification 1,094,161, and yarn is led to the shearing head along the axis of the flyer last engaging the yarn. The yarn is pulled off the packages by haul pulleys between the shearing head and the take-up.

Title: Means for Controlling Acceleration or Deceleration of a Wheel

IPC: B60L15/20
Filed: 1967-05-23
Abstract: 1,157,174. Fluid pressure brakes. GIRLING Ltd. 6 May, 1968 [23 May, 1967; 12 Oct., 1967], Nos. 23883/67 and 46582/67. Heading F2F. [Also in Division G1] Each of the wheels of a vehicle incorporates electric acceleration measuring apparatus whereby the brakes are released if the wheel decelerates too quickly, or locks. As shown, the wheel drives an alternator 11 to produce a signal voltage representative of speed, which is rectified at D2-D5, smoothed at R9, R10, C7, C3, C4 and differentiated at C2, R1, R2 to obtain an acceleration signal voltage which is fed to the base of transistor Q1. This transistor is normally conducting via resistors R1, R2 allowing the subsequent transistors Q2-Q5 also to conduct, the current flow through Q5 being insufficient to energize relay winding 21. Positive acceleration produces an additional positive signal at Q1 which does not affect the circuit conditions. Deceleration produces a negative signal at Q1 which reduces its conduction current and allows the conduction current of the other transistors to increase. At a predetermined deceleration, established by variable resistor 22, the current through Q5 energizes relay winding 21 to release the brakes. The circuitry ensures that the brakes are held released even if the wheel locks. The acceleration signal may alternatively be fed to the base of Q2, thereby energizing relay winding 21 at a predetermined acceleration to prevent further power being provided to the wheels. The system is tested by a switch 24, which, when closed and then opened, produces a nominal deceleration signal which should momentarily energize winding 21. Automatic temperature compensation is provided by thermistor 23 and resistor R11. The circuit is energized by a battery 19 which is continuously charged by the rectified speed signal voltage, or battery 19 is replaced by a capacitor charged by this voltage.

Title: Ammonia synthesis process
IPC: C21B13/00
Filed: 1964-02-14
Abstract: A hydrogen-nitrogen mixture for the synthesis of NH3 is prepared by reducing iron ore (e.g. Fe3O4) with a reducing gas obtained by partially oxidizing a carbonaceous fuel with O2-enriched air, with or without steam, so that, after reduction of the iron ore, there is a molar ratio of CO + H2 to N2 of 2.8-3.5, subjecting this crude gas to a water shift reaction to convert CO to CO2 and H2O to H2, and removing CO2 and H2O, thereby obtaining a gas of H2 to N2 ratio of 3 suitable for NH3 synthesis.  The fuel may be coal, coke, carbon or a hydrocarbon fuel, e.g. methane or naphtha.  The iron ore reducing gas may be prepared by partially oxidizing methane with air containing 21-85% by volume O2 and 0-3 lb. moles of steam per lb. atom of carbon in the natural gas at 1500-3000 DEG  F. and 1-40 atmospheres pressure to obtain a gas with a ratio of H2 + CO to N2 of 3.1-4.5 which is used to reduce iron ore to iron. The iron ore reduction may be carried out in two stages at 800-1800 DEG  F. and 1-40 atmospheres pressure.  The water shift conversion reaction is performed at 600-900 DEG  F. and 2-12 atmospheres pressure.  The ammonia synthesis may be carried out at 750-1200 DEG  F. and a pressure of 100-1000 atmospheres, whereby there is obtained 8-85% conversion, per pass of the reactants, to NH3.
