Title: Improvements in suction control for cigar wrapper carriers for cigar making machines
IPC: A24C1/28
Filed: 1928-09-06
Abstract: 304,109. Marks, Sir G. C., (Intemational Cigar Machinery Co.). Sept. 6, 1928. Cigar-making machines.-In a wrapper carrier in which a wrapper is held by suction against a detachable cover plate 26 forming a wall of the suction chamber 25, the suction is automatically cut off from the chamber when the cover plate is detached, for instance, when the wrapper carrier runs idly at the beginning of a new run of the machine. As shown, the chamber 25 forms the end of a hollow arm 9 pivoted on an arm 10 which is mounted on a hollow shaft 11 connected to a suction pump or fan, the swinging arms 9, 10 being controlled from a stationarv cam 13. The cover 26 has open slots at its ends engaged respectively by a bolt 27 and a spring-pressed cone-headed pin 28. A partition 33 in the suction chamber, in register with a partition 53 in the cover 26, is provided with a butterfly valve 34 adapted to admit suction to one or both compartments of the chamber. The valve turns on a spindle 52 carried by a removable block 54, in which are housed spring-actuated plungers 48, 57 acting upon ball-headed pins 55, 56 riveted to the valve spindle 52. On the removal of the cover 26, a spring 58 moves the plunger 48 and the valve 34 into the position shown in Fig. 7, in which the valve engages seats 49, 50 and cuts off the suction from both compartments. The plunger 57 is actuated by a valve rod 35 carrying at the upper end a roller 36 in a bracket 37 pivoted on the rod 35 and held by a pivot spring in an upright position against a stop. In the forward movement of the wrapper carrier, while the first portion of a wrapper W is being fed to a cigar bunch C, Fig. 5, the roller 36 passes idly over a fixed earn 42, and the valve 34 is held open by the spring 59 acting on the plunger 57. On the return movement, when the forward part of a wrapper has been fed to a cigar bunch, the rod 35 and plunger 57 are depressed, turning the valve into engagement with the seats 50, 51 and cutting off the suction from the forward compartment of the suction chamber.

Abstract: 831,613. Refrigerating. SULZER FRERES S.A. Aug. 16, 1957 [Aug. 17, 1956], No. 25980/57. Class 29 [Also in Group XXVIII] Gaseous refrigerant, e.g. hydrogen compressed by compressor 1 and cooled by heat exchangers 2, 4 is expanded in turbines 5, 8, 11 between which are heat exchangers 7, 10. As shown in Fig. 1, refrigerant from turbine 11 flows in part through pipe 12 and exchangers 10, 7, 4 to cool the refrigerant flowing to the turbines, and in part through passage 16 in heat exchanger 17 to cool or liquefy medium flowing through passage 19. Both parts of the refrigerant return to the compressor intake. In a modification, exchanger 17 is dispensed with and the medium to be cooled or liquefied flows through third passages 38, 39, 40 in exchangers 4, 7, 10. In a further modification, there is an additional heat exchanger downstream of turbine 11 and this heat exchanger and exchangers 7, 10 cool a medium to be cooled or liquefied. The cold gas returning to the compressor passes only through exchanger 4. In the system of Fig. 3, in which the refrigerant itself is to be liquefied, the cold gas from exchanger 10 divides at point 26<SP>1</SP>, part passing through exchangers 46, 49, 57 and turbines 44, 47, 50 and the other part passing through the heat exchangers in which it is cooled and throttles 53, 55, 58 to liquid receiver 59. Flash gas from the receiver joins refrigerant from turbine 50 at point 51 and the mixture flows through exchanger 57 to point 66, whence one part flows through exchangers 10, 7, 4 to cool the compressed and partially expanded refrigerant and the other part flows through exchanger 17 to cool make-up gas fed in by pipe 65 and precipitate impurities therefrom. The make-up gas joins the circulating refrigerant at point 64.

IPC: B01F33/40
Filed: 1950-10-26
Abstract: In maintaining solid particles in suspension in a liquid capable of growing such particles, the process being particularly applicable to the production of alumina by the Bayer process, the particles formed are allowed to settle to the <PICT:0721995/III/1> bottom of a vessel 1 at a speed determined by their size, wherefrom they are caused to rise as a gasified suspension through pipe 4 arranged at an adjustable depth over a compressed air inlet valve 2, which suspension is distributed at the surface of the liquid by a blade wheel 7 carried by an open work support 6 at the top of pipe 4.  The suspension passes through holes 11 into an annular chamber formed by ring 9, clear liquid being discharged over weir 14, heavier particles returning to vessel 1 through holes 10, and lighter particles with attached air bubbles being carried to the upper part of the liquid through holes 12.  In normal operation, the level of the liquid in ring 9 is higher than that in the main vessel.  When it is desired to withdraw the suspension, a ring 23, communicating with tubes 20, 24 connected by a rubber sleeve or hinge 21, is lowered over the blade wheel 7. Specification 653,741 is referred to.

Filed: 1921-10-07
Abstract: 191,439. Grafton, W. F. Oct. 7, 1921. Spray carburettors. - Air to be carburetted is admitted past a rectangular choke tube A<2> by withdrawal of a member g as shown in Fig. 3 which is a section on the line CC, Fig. 5. Fuel is admitted to a nozzle P past a needle-valve S which is raised by engine suction acting on a piston t through a passage Q. The lift of the needle S is limited by a lever H having an adjustable plate O which contacts with a projeetion g<1> on the member g. The suction also acts through a hole Q<2> on a piston U which, moving against a spring w, rotates a spindle on which the lever H is eccentrically mounted. By this means the fuel supply is reduced automatically when the speed of the engine increases. The fuel supply may also be controlled by a hand-actuated cock in the tube r. A recess is made in the end of the member g to accommodate the end of the nozzle P. and whistling is prevented by providing the recess with a loose piston which is drawn forward by the suction to close its mouth. The plungers U and t are preferably made of graphite.
