Title: Improvements in or relating to sliver lapping machines
IPC: D01G27/04
Filed: 1952-04-09
Abstract: 717,719. Lap-forming apparatus. CONSTRUCTIONS MECANIQUES LORRAINES, [formerly LALEVEE, PERAGIN & CIE]. April 9, 1952 [April 23, 1951], No. 9116/52. Class 120(1) A sliver lapping machine of the. type in which the sliver roll is formed between driving cylinders and a movable press cylinder, sliver feeding means can be declutched on completion of a roll, and vertically - movable racks are adapted to move the roll upwards on completion, is characterized in that the clutch members are engaged and disengaged by an electromagnet and an electric motor is used to impart up-anddown movement to the racks. As shown, Fig. 1, slivers 1 fed by take-up rollers 2 pass as a sheet between fluted drawing rollers 3, 4 to be wound into a roll 5 on a core held between the flanges 8 each revolvably carried by a rack 9, Fig. 4. The roll is formed between driven winding rollers 6 and a press roller 7 carried by two further racks 10 which are geared to racks 9. A motor 16 drives rollers 6 and, through a clutch, rollers 2, 3 and 4. A reversible motor 19 drives the racks. During roll formation, motor 19 is not energized and the racks are free to rise. When the roll has reached the desired size, suitably positioned projections on two toothed wheels geared to rollers and 4 engage each other and cause one of the wheels to shift so as to close two switches; the first switch energizes an electromagnet to disengage the clutch in the drive to rollers 2-4, thus stopping sliver delivery and breaking the sliver sheet; the second switch starts motor 19 in a direction to cause racks 9 and 10 to rise, gearing between the racks causing racks 10 to rise more than racks 9 so that roll 5 becomes spaced from both rollers 6 and 7. Engagement of a crank 66, carried by a rack 9, with a fixed stop 67 causes the crank to rotate so as to retract one flange 8; also, a rod 80, Fig. 6, pivoted at 72 and slidably connected to a rack 10, is rocked by the upwardly moving rack so as to release a weighted arm 76 from a hook 77 to cause an ejector 73 to urge the roll 5 into a storing chamber 71, while an empty core 70 from a magazine 69 is released by arms 74, 75 to roll down on to rollers 6. At the end of the upward movement of the racks a stop 12 on an arm 11 carried bv a rack 10 operates switches 13, 14 to stop motor 19 and then start it in the reverse direction so as to lower the racks. Downward rack movement restores ejector 73 and the coreloading means to their inoperative position and causes crank 66 to be moved by engagement with a lever 68 to engage flanges 8 with the empty core 70. When the racks are at the end of their downward movement, a further stop 12 on arm 11 engages a switch 15 to stop motor 19 and de-energize the electromagnet; the drive to rollers 2-4 is thereby re-clutched to start a new winding operation. Manual controls are provided for causing the racks to move in either direction if required.

Title: An improved method and apparatus for the treatment of gases, oil vapours, or gaseousmixtures
IPC: B01J10/00
Filed: 1921-03-31
Abstract: 186,945. Ward, J. F., Nielsen, H., and Laing, B. March 31, 1921. Gases, treating with liquids.-Relates to the treatment of gases or vapours with a liquid medium, which may contain catalytic or other solids in a mechanical or colloidal state in suspension therein, in centrifugal or cycylonic apparatus, in order to cause the liquid or the suspended solid to absorb one or more constituents of the gases or else to promote a reaction between the gases and the liquid or the solid. The process may be employed for the simultaneous disulphurization and hydrogenation and/or oxidation of gases or oil vapours by means of catalysts and/or oxidizing agents in the presence of ammonia, which may be supplied by means of producer gas. The centrifugal or cyclonic apparatus may be so constructed that the reaction may take place at a pressure above or below atmospheric. In the preferred apparatus the gas or gases to be treated enter the treating vessel a tangentially and at great speed through an inlet c, the liquid containing the desired solid being kept at the desired temperature by means of a heating or cooling jacket b. The gas travels spirally round the inner surface of the chamber a and is forced bv incoming gas downwards towards the centre of the apparatus where it is forced by rapidly rotating propellers g vertically upwards through a rotating basket or mixing chamber h carried by a central tube f, the gas being eventually forced through openings e<1>, d<1> in baffle plates to the outlet d. While in the vessel a and during its passage through the basket h, the gas is mixed intimately with a portion of the liquid and contained solid which is forced up the centre tube f by an injector m supplied with a portion of the gas by a compressor n, the liquid being discharged into the basket through radial pipes and sprayed through perforations in the basket across the vessel a. Fresh liquid may be fed into the apparatus and spent liquid discharged continuously during the operation. Any desired number of baskets may be mounted on the tube f, and two or more complete apparatuses may be arranged in series or in parallel, the gases or vapours receiving the same or different treatment in each. The basket is preferably rotated in the direction opposite to that of the incoming gases, but where two or more baskets are employed in the same or different apparatus, they may be arranged to rotate in opposite directions.

Filed: 1944-05-19
Abstract: 592,799. Counting-apparatus. NATIONAL CASH REGISTER CO. May 19, 1944, No. 9751. Convention date, May 6, 1943. [Class 106 (i)] [Also in Group XL] In an electronic counter comprising a bank of normally non-conducting valves arranged so that upon conducting each prepares the next, the number of valves is less than the number of digits, each pulse causing the combination of conducting valves to change until when the number of pulses equals the number of digits, all the valves are conducting. For counting up to ten pulses, four gasfilled valves 10-13 are fed with positive pulses over conductor 30, valve 10 being fired by each pulse, the remaining valves being so biassed that one is only fired if the preceding valve is conducting. The firing of any valve extinguishes all the preceding valves over the coupling condensers 40 between the cathodes but succeeding valves are not extinguished due to the rectifiers 41, 60, 99. Operation. The first pulse fires valve 10, the rise in cathode potential reducing the negative bias on the grid of valve 11 which fires upon the receipt of the second pulse, the rise in cathode potential causing over coupling condenser 40 the cathode potential of valve 10 to rise above the anode, thus extinguishing the valve. The third pulse fires valves 10 and 12, the rise in cathode potential of valve 12 extinguishing valves 11 and 10, the fourth pulse firing valve 13 and valve 10, the former extinguishing valves 12 and 10. Upon receipt of the fifth pulse valve 10 only fires and after the sixth and seventh pulses valves 11 and 12 respectively remain conducting. The process continues, Fig. 2 (not shown) until after the tenth pulse, all the valves are conducting. A resetting pair of trigger valves 70, 71 is arranged so that valve 70 is normally conducting, the grid of valve 71 being biassed beyond cut-off over resistance 93. As each of the valves 10-13 fires the rise in cathode potential causes, over resistances 95, a rise in the grid potential of valve 71 until when all the valves are conducting, valve 71 conducts, driving valve 70 into the' cut-off condition. The consequent rise in anode potential of valve 70 delivers a positive pulse over condenser 112 to extinguish all the valves 10-13, the trigger pair being returned to normal. The pulse from the anode of valve 70 may be used to transfer to a higher denominational counter.
