Title: Method of and Apparatus for Charging Gas Retorts.
Inventor: WHITE ALFRED ERNEST
IPC: C10B31/06
Filed: 1916-04-07
Abstract: 107,775. White, A. E., (Riter-Conley Manufacturing Co.). April 7, 1916. Automatic - f e e d weighers. - Relates to means for controlling the action of an electrically - operated machine for supplying a weighed charge of coal to a charger or scoop which is inserted successively into the various retorts of a bench. The action of the various parts of the machine is controlled to produce an automatic cycle of operations. The coal is contained within a bin or hopper 2 at the top of the machine and is delivered by endless conveyers 41 to a receptacle 15 which can be rotated to dump a weighed charge into the shoot 8 leading to the charger. The shafts 15<a> of the dumping receptacle 15 are supported in end yokes 18, Fig. 5, suspended by links 22 from arms on shafts 20, 21 carried by knife-edge bearings. Mounted on the shafts 20, 21 are arms 28, 29 connected by links 31 with a steelyard arm 33, having a counterbalancing weight 38, and adjustable poise 37 working on a graduated scale. The conveyers 41 and the bucket 15 are operated through suitable gearing by separate electric motors, controlled by automatic switches, the circuits of which are described. Assuming that the receptacle 15 contains a charge, and that the charger is in the receiving position, the starting circuit of the motor operating the receptacle is completed by the charger. After a short interval the circuit is rearranged under the control of the automatic switch of the motor operating the receptacle and the movement is continued until, after a complete revolution of the reeeptacle, the circuit is broken. During the final movement of the automatic switch a circuit which includes an interruption closed by the steelyard beam, when the receptacle 15 is empty, is completed to set the "forward" starting switch of the motor operating the conveyers 41 in a mechanically locked position. The motor then operates until the weight of coal fed to the receptacle 15 tilts the steelyard beam to complete a circuit through the automatic controller of the motor. This circuit unlocks the " forward " switch and sets the " reverse," and the motor continues in operation until the switch is unlocked by the completion of a circuit by the automatic controller. The conveyers are reversed only through a short distance, say four inches, to prevent any coal falling into the receptacle by the jarring of the machine. A registering mechanism may be provided for counting the number of revolutions made by the receptacle 15.

Title: Process for the continuous production of polyolefines of uniform molecular weight
IPC: C08F10/00
Filed: 1956-02-21
Abstract: A Ziegler catalyst for use in the continuous production of polyolefines, is stabilized by using in an initial polymerization at about 20-60 DEG  C. and for a short residence time in a pre-reactor before continuously introducing into the main reactor which is at a higher temperature, e.g. about 80 DEG  C.  In an example the catalyst is formed by mixing aluminium diethyl chloride and titanium tetrachloride in cyclohexane.ALSO:Polyolefines of uniform molecular weight are obtained by a continuous process using Ziegler catalysts, characterized in that the catalyst is used in an initial polymerization at about 20-60 DEG  C. and for a short residence time in a pre-reactor, and is then continuously introduced into the main reactor which is at a temperature above that of the pre-reactor, e.g. at about 80 DEG  C. In the example ethylene is polymerized with cyclohexane as diluent and with a catalyst formed from aluminium diethyl chloride and titanium tetrachloride.  The apparatus used consists of 3 reaction columns through which the reaction components flow.  In the first column the catalyst components and diluent are mixed and then flow into the second column, at 20 DEG  to 60 DEG  C., into which ethylene is also introduced.  The residence time in this pre-reactor is 10 minutes and the catalyst and reaction medium containing some polymer then passes into the third column into which further ethylene and cyclohexane are also introduced.  The residence time in the third column is 3 hours.

Abstract: 679,577. Fluid-actuated valves. HAWKER AIRCRAFT, Ltd. Feb. 19, 1951 [March 2, 1950], No. 5333/50. Class 135 [Also in Group XIII] A butterfly valve controlling the supply of air to a turbocompressor and heat exchanger system so as to keep the ratio of inlet and outlet pressures of the turbine constant, is actuated by diaphragms or bellows which are subject to those pressures. In one form, Fig. 2, two rigidly connected diaphragms 34, 35, each subject to one of the pressures, are of unequal diameters, the diameter ratio being equal to the desired pressure ratio. The space between the diaphragms is evacuated, and springs 42, 43 maintain them in a central position at the desired pressure ratio. The diaphragms actuate a lever 37 connected to the valve. In another form, Fig. 4, a floating lever 71 operating the valve 32 through a linkage 72 is connected to a spring link 76 and to bearings 68, 69 in the crossheads 66, 67 of pairs of bellows 62, 63 and 64, 65. The bellows 63, 65 are evacuated, and the bellows 62, 64 are subject to the outlet and inlet turbine pressures respectively. Changes in the ratio of these pressures cause the lever to rock, and changes in atmospheric pressure tend to move the lever bodily. In a simpler form, the spring link 76 is dispensed with, and the lever has a fixed pivot between the cross-heads. In another modification, the bellows corresponding to 65 as well as that corresponding to 62, is subject to the outlet turbine pressure, the lever engages in sleeves pivoting in the cross-heads, and a spring link also connects the lever to one of the cross-heads, the spring link 76 being dispensed with. An adjustable stop for the free end of the lever is provided, to limit the outlet pressure of the turbine. Specification 674,364 is referred to.
