Title: Textile fiber bale opening and blending method and apparatus
IPC: D01G7/04
Filed: 1961-02-10
Abstract: 937,262. Opening bales of and blending fibres. CROMPTON & KNOWLES CORPORATION. Feb. 10, 1961 [Feb. 10, 1960], No. 5065/61. Classes 120 (1) and 120 (3). Fibres are torn in tufts from bales and blended by arranging for a plurality of bales to be reciprocated over a row of tables associated with rotary toothed members that tear the tufts from the lower faces of the bales and deposit them on a conveyer in such manner that layers of tufts from different bales accumulate on the conveyer. Bales 3 of fibres that are to be blended are placed on rows 16 of tables 15, each row 16 being in line with a feeder 1 which may be a hopper feeder provided with a weigh pan or may be a feeder that includes a series of beater rolls disposed on an inclined housing member shaped to conform to the rolls. Between each table 15 a slotted sheet forms a bridge 30 and under the bridge is arranged a rotary plucker member carrying pins 32 that remove tufts of fibres from the bales 3 as the latter are reciprocated over the tables. Brushes 60 co-operate with the plucker members to sweep the fibre tufts on to a conveyer 2 that supplies the feeder 1. Instead of the brushes 60, fibres may be removed from the pins 32 by air blasts. Each feeder 1 will have presented to it a web of fibres consisting of layers of tufts taken from each of the bales 3. When each of the feeders 1 has weighed a predetermined amount of the commingled fibres, the scale pans of the several feeders are opened and the fibres discharged on to a conveyer 8 for transport to a cleaning and blending machine 9, the discharges taking place either simultaneously or consecutively. U.S.A. Specification 2,412,508 is referred to.

Title: Preparation of organic nitriles
Inventor: WEBB IRVING DILLAYE
IPC: C07D333/24
Filed: 1948-02-25
Abstract: Nitriles having the unit <FORM:0639438/IV (b)/1> are prepared by heating a halide possessing the unit <FORM:0639438/IV (b)/2> , where X is chlorine or bromine, with hydrogen cyanide or an alkali metal cyanide or an alkaline earth metal cyanide in an aqueous acid medium, the reactant cyanide acting also as an acceptor for hydrogen halide. Any acid, e.g. sulphuric or oxalic, may be added.  The initial halides may be alicyclic, e.g. 1 : 4-dichloro-2-cyclopentene, heterocyclic, e.g. 2 : 5-dichloro-2 : 5-dihydrofuran, or of the type R1R2C = CR3.CH2X or R1R2CX.CR3 = CH2, where R1 is alkyl, alkenyl, chloroalkyl or cyanoalkyl, R2 and R3 are hydrogen or methyl, being the same or different, or the following: benzyl chloride, benzal dichloride, benzotrichloride, triphenylmethyl chloride, phenallyl chloride, a -vinyl allyl chloride and g -dichloroallyl chloride; the halide preferably contains 4-10 carbon atoms.  Usually a substantial excess of cyanide is added, the pH is kept below 3, and the temperature is in the range 50-180 DEG  C.; cooling is often necessary.  Lower temperatures favour the formation of chloro-nitriles from dichloro-compounds.  Catalysts such as copper, copper or cobalt salts and potassium ferricyanide may be used.  The water content of the reaction medium is preferably 0.2 to 10 times the weight of CN residues present.  The reactants may be emulsified, or an inert miscible or immiscible diluent may be used.  In the examples: (1)-(3), (5), (7) and (11) 1 : 4-dichloro-2-butene is treated with hydrogen cyanide, or sodium or calcium cyanide, under a variety of conditions to give 1 : 4-dicyano-2-butene, also prepared (6) from 3 : 4-dichloro-1-butene in a similar way (some chloro-nitriles are formed in most cases); (4) 3-chloro-1-butene treated with hydrogen cyanide gives crotyl cyanide; (8), (9) and (12), allyl bromide, isobutenyl chloride and 2-chloromethylthiophene are treated with sodium cyanide to give the corresponding nitriles.

Title: Improvements in hectographic copying machines
Inventor: BROWN ROLAND
IPC: B41L9/10
Filed: 1953-03-02
Abstract: 732,157. Duplicating machines; feeding sheets. BLOCK & ANDERSON, Ltd. Feb. 23, 1954 [March 2, 1953], No. 5767/53. Classes 100 (1) and 100 (2). In a duplicating machine of the kind in which the copy sheet is fed to the printing couple by a pair of feed rollers driven at first from the initial rotation of the master cylinder from zero position and thereafter rotated idly by the tension of the sheet as it is drawn through the printing couple, means are provided whereby after the first rotation of the cylinder the drive to the feed rollers is automatically disconnected so that, when making copies of a length greater than the circumference of the master cylinder, the feed rollers are not driven when the cylinder starts its second revolution. The feed-roller driving arrangement is as described in Specification 682,842 and employs a cam 15 on the master cylinder 2, acting through a spring-loaded follower-lever 16 to oscillate a toothed quadrant (not shown) meshing with a gear having a unidirectional coupling with one of the feed rollers 13, 14. By this means the initial rotation of the cylinder 2 causes the sheet fed to the feed rollers to be advanced to the printing couple. When the follower roller 17 of lever 16 encounters the fall part of the cam 15 the drive to the feed rollers ceases and they rotate idly as the sheet continues its progress through the printing couple. When taking copies of length greater than the circumference of the cylinder 2 further rotation of the feed rollers is prevented by a latch 20 arranged to engage an arm 19 of the lever 16 and hold it the extreme (anticlockwise) position. The latch 20 is normally held inoperative by a catch lever 22 pivoted at 23 and spring loaded so that a notch thereon engages a pin on the latch. When it is desired to print long copies a finger 25 is thrown over in a clockwise direction so that a disc 26 attached thereto engages the catch 22 and releases latch 20. When the follower 17 reaches the highest point of cam 15, i.e. at the end of the drive to the feed rollers, the lever 16 is latched against movement in the opposite direction under the influence of the spring. The latch is re-set by movement of the manually operated lever 12 adapted to displace the impression roller 3 out of contact with the master cylinder during reverse rotation necessary for unwrapping the master sheet between printing operations. For this purpose there is attached to latch 20 a link 27 having a pin 28 for engagement with the rear of the lever. A spring loaded arm 6 carries a roller 7 which normally engages in a notch 5 in a disc 4 on the master cylinder to locate the cylinder at the end of each printing operation. Rotation of the finger 25 also causes the arm to be displaced to an inoperative position so that there is no locating action at the end of each rotation of the master cylinder.

Filed: 1920-02-27
Abstract: 139,514. Westinghouse Lamp Co., (Assignees of Rentschler, H. C.). Feb. 27, 1919, [Convention date]. Vacuum tubes; low-pressure metallic-vapour apparatus.-A tube having an electron-emitting cathode 5, a plate anode 4, and an intermediate grid 6, is filled with a medium such as argon or metallic vapour which exhibits the phenomenon of " resonance potential," the grid being maintained at a positive potential with respect to the anode and cathode. It is stated that the impact of primary electrons on gas particles is elastic or non-elastic, depending on the velocity of the electrons as determined by the potential of the grid, such primary electrons either passing through the gas particles to the grid, or rebounding, when the impact is elastic, or passing with reduced velocity when the impact is non-elastic; the latter phenomenon is termed " resonance " potential." In the case of argon at a pressure of a fraction of a millimetre to several millimetres, the phenomenon occurs with a positive potential of about 12.3 volts applied to the anode, the rate of change of the resultant anode current with increase of grid potential, being then zero. The tube may be used as a detector or amplifier of wireless signals, or as a frequency-doubler. Specification 15555/15 is referred to.
