Title: Improvements in or relating to the manufacture of cigarettes
IPC: A24C5/52
Filed: 1950-10-02
Abstract: 711,783. Cigarette making machines. MOLINS, D. W., RUAU, F. F., JACKSON, N. W., and MOLINS MACHINE CO., Ltd. Oct. 2, 1951 [Oct. 2, 1950], No. 24065/50. Class 130 A method of increasing the density of a,. tobacco filler at desired positions therealong, e.g. in the production of dense-end cigarettes, consists in engaging the filler at a part near each said position and displacing tobacco lengthwise of the filler, and also engaging the filler adjacent each said part and displacing a smaller quantity of tobacco than that displaced by the first displacement in the same direction as the first displacement. The filler, formed in a passage P in a continuous rod machine as described in Specification 646,746, passes to the tongue 2 of the wrapping mechanism, above which rotates a wheel 3 carrying groups of fingers 4A-4D projecting through a slot and moving in the same direction as, but faster than, the filler, each group of fingers being arranged to enter the filler in the region of a point at which it is desired to increase the density e.g. at the points at which the wrapped filler is subsequently cut. The fingers 4A-4D of each group are of progressively decreasing lengthso that each in turn penetrates less deeply into the filler. The leading finger 4A, due to its faster motion, displaces tobacco forward to cause a local increase in density, the succeeding fingers in each group displacing successively smaller amounts of tobacco forward to partly replace the tobacco displaced by the preceding finger, whereby a gap in the filler is avoided. The Provisional Specification describes a modification in which the fingers are arranged to move slower than the filler. Specification 689,590 also is referred to.

Patent GB-851700-A (GB)
Title: Method and apparatus for sealing water formations in a well
IPC: E21B33/138
Filed: 1959-07-20
Abstract: 851,700. Stabilizing earth formations. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. July 20, 1959 [July 21, 1958], No. 24840/59. Class 68(1). A water formation traversed by a well borehole is sealed by lowering into the well, at the end of a pipe string, a predetermined volume of a sealing fluid in a container of drillable material, the container being positioned adjacent to the formation to be sealed and then subjected to fluid pressure applied through the pipe string sufficient to force the sealing material from the container into the annular space between the container and the wall of the well and into the said formation. Fig. 1 shows an arrangement for sealing a formation at the bottom of the borehole, the container 10 resting upon the bottom of the well and the weight or part of the weight of the drill string 15 compressing the packer 13. A sliding plug 23, preferably of rubber, is placed above the sealing fluid 22 and separates the pressure-applying fluid in the drill pipe therefrom. The pressure applied to the fluid 22 blows out plugs 20, 21 and the fluid passes into the annular space and the formation. The plug 23 seals the ports 16, 17 and prevents the superposed fluid, e.g., water from following the sealing fluid. The drill string 15 is unscrewed, either above or below the packer according to whether the threads 12 or 14 are left handed, and the sealing fluid is allowed to set around the container 10 which may be drilled away by a full-size bit, or may be allowed to remain if drilling is continued with a smaller bit. A ball is dropped through the string 15 to seat upon a valve plate 18 to prevent water from running out of the string as it is run out of the well. In Fig. 2, the apparatus is designed for sealing a formation above the bottom of the well. The packing means comprise a lower cup member 28 on the container 25, and an upper cup member 40 on a tube 36 connected by a bayonet joint 37, 38 with the container 25 and screwed into the drill string 47. To permit fluid in the well to escape as the string and container 25 are run in, the tube 36 has ports 41, 42 which are closed when the container 25 is adjacent to the formation to be sealed, by dropping a short tube down the drill string and thus striking the valve 43 down to rest upon stops 45. The resilient plug 35 may now be forced down by fluid pressure until it rests upon a grating 34 above the blow-out plug holes 32, 33. The short tube is closed by a dropped ball, the bayonet joint is uncoupled and the drill string and packer parts 36, 40 are withdrawn. The bayonet joint may be above the tube 36 if it is desired to leave this part in the well. Sealing fluids mentioned are resins, synthetic resins, plastics, synthetic plastics such as phenol formaldehyde, polyurethane, epoxy and ureaformaldehyde resins, silica gel, acrylamide gels and various gum solutions.

Filed: 1960-07-18
Abstract: 893,623. Valves. U.S. INDUSTRIES Inc. July 18, 1960 [March 8, 1960], No. 24946/60. Class 135. [Also in Group XXI] Flow control apparatus comprises a conduit 10 adapted to be positioned in a well, a sleeve 12 slidable within the conduit to open or close ports 14 in the conduit and a tool 15, 16 for sliding the sleeve and having locator members 25 engageable with projections 40, 41, on the conduit to limit movement of the tool away from the sleeve until the sleeve is fully shifted. The sleeve has slots 13 coacting with the ports 14, and spring fingers 50 engaging the conduit to hold the sleeve in position. The tool shown has its parts arranged for downward movement of the sleeve. Upshifting and downshifting sets of dogs 20, 19 mounted in the part 15 are arranged so that one set is urged towards the extended position whilst the other is retracted. The part 16 carries the locator members 25 which are biased outwardly by a spring 28 and are retractable by shearing a pin 36 which normally prevents relative axial movement of a rod 24. The tool is lowered into the conduit with the dogs 20 free to move to the extended position. When the dogs 20 are engaged below a shoulder 21 the sleeve is raised to retract the dogs 20 and permit the dogs 19 to extend. The tool is raised until dogs 19 engage a shoulder 22 and the sleeve is then jarred downwardly to its lower position (Fig. 2). Until the sleeve is fully shifted to its lower position the tool is prevented from being removed from the conduit by the engagement of the locator members 25 with the projection 40. When the sleeve is in the lower position it prevents the members 25 latching on to the projection 40 so that the tool may be removed from the conduit. To enable the tool to move a sleeve upwardly the dogs 19 and members 25 are removed, and interchanged upside down so that the upper part of the tool carries upshifting dogs and a locator member, and the lower part of the tool carries upshifting dogs. The tool is lowered within the conduit until the upper dogs are below the sleeve shoulder 21, and an upward pull on the tool causes the upper dogs to retract and the locator members to extend. On further upward movement of the tool the lower dogs engage the shoulder 21 to move the sleeve upwardly. If, on lowering the tool, the locator members engage the projection 41, the sleeve has not been fully shifted to its upper position.

Abstract: 227,182. Molins, W. E. Oct. 9, 1923. Cigarette-making machines.-Relates to apparatus for feeding oval cigarettes from a hopper and lapping them over one another. The feeding apparatus may be of the type described in Specifications 139,047 and 207,281, [both in Class 94 (i), Packing &c.]. Each cigarette as it' leaves a fluted delivery-drum or like conveyer is positively turned or tilted automatically to cause it to fall on the preceding cigarette in lapped formation and is retained in such formation during its furthere travel through the apparatus, during which the cigarettes may be grouped for packeting. In one form, Fig. 1, t'he cigarettes are removed from the fluted drum 1 by a forked plate 4, passing out of the hopper 3 below a roller 2. A pawl 5, with outer fingers 7 and a longer central finger 8, is pressed by a light spring 6 to engage the upper edges of the cigarettes, so that' a turning effect is produced which results in the cigarettes assuming the positions a, b and passing in lapped formation between a plate 9 and brush 10<a>. A conveyer 11 and pushers 10 group and forward the cigarettes as described in Specification 207,281, [Class 94 (i), Packing &c.]. To assist the turning movement, discs 12 with frictional edges may be mounted to rotate at a peripheral speed greater than that' of the drum 1 and to lift the cigarettes slightly from the bottoms of the flutes and to turn them into the position a. In a modification, Fig. 7, the cigarettes may be lapped in a reverse direction after leaving the drum. Plates 27 with projections 28 rotate above the forked plate 4 so that each projection cooperates with a stop 30<a> to tilt a cigarette into the position shown. When a group has been formed, the stop 30a falls and the group passes over a cork inset 36, the rear cigarette being supported by a stop 37 which falls behind each cigarette.
