IPC: F16P3/00
Filed: 1955-02-28
Abstract: 784,240. Machinery safety devices. GATENSBURY, F. G. Feb. 28, 1956 [Feb. 28, 1955], No. 5823/55. Class 80 (4). A screw-press has a collar 11 secured on the screw 9 which co-operates with a movable stop 13 which has to be moved aside to allow a working stroke to be effected. The stop 13 is on a rod 14 pivoted on a bracket 15 and operated by a handle 18 through a lever 16 with a weight 19 biasing the stop 13 to operative position. The operator must use one hand to move the stop 13 whilst the other operates the normal starting lever or actuates the press manually.

Title: Method of synthesizing urea
IPC: C07C273/04
Filed: 1967-02-07
Abstract: 1,131,906. Synthesizing urea. SUMITOMO CHEMICAL CO. Ltd. 7 Feb., 1967 [15 Feb., 1966], No. 5875/67. Heading C2C. A method for synthesizing urea by reacting ammonia with carbon dioxide at elevated temperature and pressure comprises reducing the pressure of the reaction product from the urea synthesis step to 25-50 kg./cm.<SP>2</SP>g. in an ejector type pressure-lowering apparatus, heating the reaction product in a first stage decomposition step, separating a generated gas from the reaction product, heating the reaction product in a second stage decomposition step under a pressure of 5-15 kg./cm.<SP>2</SP>g, separating the generated gas from the reaction product, heating the reaction product in a third stage decomposition step under a pressure of atmospheric to 3 kg./cm.<SP>2</SP>g. and further separating the generated gas, while absorbing the separated gas obtained from the first stage decomposition step under the pressure of said step in an aqueous solution obtained by absorbing in an aqueous absorption liquid the separated gas obtained from the third stage decomposition step, utilizing the absorption heat generated in said absorption of the separated gas obtained from the first stage decomposition step as a heat source for the second and third stage decomposition steps, introducing the gas-liquid mixture formed in said absorption into a medium pressure absorption step to subject the mixture to absorption treatment, reusing the resulting aqueous ammonium carbamate solution for urea synthesis, and returning the gas separated through the second stage decomposition step to the ejector type pressure-lowering apparatus. The reaction product, after separation from the gas generated under a pressure of 25-50 kg./cm.<SP>2</SP>g. in the first stage decomposition step may be further reduced in pressure to 15-25 kg./cm.<SP>2</SP>g., a gas generated is separated and introduced into the medium pressure absorption step and the reaction product is then further introduced into the step subsequent to the first stage decomposition step. The aqueous absorption liquid employed to absorb the gas separated from the third stage decomposition step may be water or an aqueous urea solution. A suitable form of apparatus is described for effecting the process.

Abstract: 1,254,162. Valves. HARPER-WYMAN CO. 4 Feb., 1969 [21 Feb., 1968], No. 5952/69. Heading F2V. Gas flow to a main burner 28 is shut off by a safety valve 20 when a pilot burner 30 is extinguished. The valve is actuated by a lever 24 acted upon by a thermal power element 22, 46. The lever carries a hook 66 engageable with pivot pins 62 to define the pivot point of the lever. The lever also carries an adjustable member such as the screw 70, defining the point of application of the actuating force at the element 22. This member 70 is retractable to allow the lever to be readily assembled, and in its adjusted position for operation of the valve prevents disengagement of the hook. The device gives precise determination of the short lever arm between the pivot and element 22, without tolerance or assembly difficulties. Two pivot pins carried by opposed side walls 12b of the valve housing 12, are provided. The housing is closed by a cover.

Title: Improvements relating to the feeding of cotton and other textile waste to willows or other machines
IPC: D01G23/08
Filed: 1925-03-05
Abstract: 236,858. Field, F., Field, H., and Field, E. March 5, 1925. Feeding openers &c. - An arrangement for feeding cotton &c. waste to willows or other machines comprises an air trunk 3 with branches leading to a number of collecting-chambers 4, 5 one for each, machine, and automatic control mechanism to divert the supply of waste from one chamber to another and to discharge the waste from the chamber thus cut off from the supply. The waste is fed by a continuously running fan 1 along the trunk 3. At the branch 6 leading to the chamber 5 is a valve 7 which can be turned to close the trunk and cause the waste to pass into the chamber 5 or to cut off the chamber 5 and allow the waste to pass into the chamber 4. Each chamber is covered with canvas to allow egress of the air and is provided with weighted doors geared together by quadrants 17, 18. The valve 7 and the doors are operated by tappet arms 27, 28, 39, 38 on shafts 30, 34 driven at the same speed by reducing gearing 33 from the fan shaft.

Title: Improvement in let-off means for looms
IPC: D03D49/06
Filed: 1927-03-03
Abstract: 267,498. Harris, W. March 13, 1926, [Convention date]. Addition to 248,348. Letting-off warps.-In let-off motions of the kind claimed in the parent Specification, the paying-out means for the endless chain is locked against independent rotation by the employment of a self-locking gear such as a worm and wheel, and the increase or decrease of the bight in the chain controls resilient toggle mechanism adapted to cause sudden engagement or disengagement of the devices for effecting the paying-out of the chain. The endless chain B, Fig. 1, passes around a sprocket 6 on the warp beam A, idler sprockets 7, a sprocket 23 on a weighted lever 25, and a sprocket 8 on a worm wheel 9 in mesh with a worm 11 on a shaft 12 adapted to be adjusted by a hand wheel 13. A pawl 15 operated by a flexible connection 17 from a crank 2a engages ratchet teeth on a wheel 14 secured to the shaft 12 to effect the paying-out of the chain at a rate greater than the rate at which the sprocket 6 takes up the chain the bight B'. The weighted lever 25 is thereby lowered and by an extension 25<a> rocks a bell-crank lever 21 connected at 22<b>, Fig. 2, by a spring 22 to a disc 19 loose on the shaft 12. When the upper part of the lever 21 has moved to the right past the line joining the point 22<b> with the centre of the shaft 12, the spring 22 causes the disc to move suddenly in a counterclockwise direction into the position shown in Fig. 2, and thereby to mask the pawl 15. The motion of the disc is limited by stops 19a adapted to engage a fixed part 20. When the lever 21 has turned sufficiently in a counterclockwise direction due to the shortening of the bight B<1>, the disc 19 is turned suddenly from the position shown in Fig. 2 to enable the pawl 15 to engage the teeth of the ratchet wheel 14 through a cut-away part of the disc.

Abstract: 783,054. Gasifying pulverulent fuel. KOPPERS GES., H. Feb. 28, 1956 [March 15, 1955], No. 6232/56. Class 55 (1). [Also in Group XIII] The sensible heat of gas generated in a gasifying chamber 1 into which fuel, for example pulverized coal, and oxygen are supplied through water-cooled nozzles 2 is utilized to raise steam in a boiler 7 which is mounted directly above the chamber 1. The boiler consists of a cylindrical vessel in which is disposed a central tube 8 the lower end of which abuts the gas discharge opening 5 of the gasifier. A series of return tubes 10 are arranged in concentric rows around the tube 8, the lower ends of these tubes opening into a chamber 11 from which pipes 12, in which are disposed superheaters 15, lead to cyclone dust separators 13. The upper ends of the tubes 8, 10 open into a gas reversing chamber containing a superheater 27, the chamber being closed by a domed cover having a water jacket in which feed water is preheated. Gases and entrained ungasified fuel from chamber 1 pass upwardly through the tube 8 wherein gasification continues and the tube is heated radiantly. The gases pass from the tube 8 over the superheater tubes 27 and through the tubes 10 into the chamber 11 wherein the larger particles of dust are deposited. Some of this dust is returned in the hot state to the chamber 1 through pipes 18 whilst the rest discharges at 17. Fine dust is removed in the separators 13 from which gas is withdrawn through pipes 14. Preheated water enters the shell 7 through a pipe 22, the steam generated being conducted to a steam collector through a pipe 23.
