Title: Method of and apparatus for making filtering material for cigarettes
IPC: A24D3/02
Filed: 1967-05-31
Abstract: 1,124,434. Corrugating fibrous webs. CELF1L CO. ESTAB. 31 May, 1967 [31 May, 1966], No. 25040/67. Heading D1S. A web of fibrous material is treated to render it particularly adapted to be gathered laterally and enclosed in a wrapper to make a filter cord subdividable into effective filters for cigarettes, by advancing a moistened essentially inelastic web 1 of the material through the nip between a pair of meshing heated corrugating and stretching rollers 8, 9 having narrow circumferential grooves 20 alternating with narrow circumferential ribs 21 whereby the web is longitudinally corrugated and laterally stretched to loosen and expose fibres without substantial impairment of the transverse continuity of the web 1, and advancing the corrugated and stretched web 1 emerging from the nip in contact with the roller 9 through an appreciable wrap angle to partially dry and reharden the web to preserve the structure imparted thereto by passage through the nip. As shown in Fig. 1, the smooth web 1 passes from a roll 2 through perforating apparatus, preferably comprising a pronged or toothed roller 3 and a counter roller 4 one of which is driven, to produce irregularly-shaped frayed portions extending out of the plane of the web. The perforating device 3, 4 may be followed by a similar device, e.g. rollers 3, 4 with their positions reversed to form frayed projecting portions on the other side of the web. The web 1 is then rendered yielding by passage through a moistening device comprising a rotating metal roll 5 dipping into a water bath 6 and a rubber pressure roller 7. Alternatively, the web may be rendered yielding by spraying it with a liquid or by submitting it to a steam treatment. The web 1 then passes around meshing grooved corrugating and stretching rollers 8, 9, 10, see also Fig. 2, all of which are preferably adjustably heated, e.g. by interior electrical heaters, to a temperature between 100‹C and 500‹C. Preferably, the rollers 9, 10 mesh to a greater extent than the rollers 8, 9 to deepen the corrugations and further laterally stretch the web 1. After each corrugating step, the web 1 remains in contact with the roller 9 or 10 for a wrap angle of 180‹ to effect partial drying. The web 1 is directed by idler rollers 11, 12 to drying apparatus 13 and then passes between rollers 14, 15 at least one of which is driven and at least one of which has a coarse knurled surface to deform the corrugations in an irregular manner. Alternatively, the web 1 may be flattened somewhat by fine knurled or smooth surfaced rollers. The web 1 passes around a rotating drying drum 16 heated by electrical heating elements or hot air to completely reharden and set the web 1. Finally, the web may pass between perforating rollers 17, 18 similar to rollers 3, 4. Alternative arrangements of two to four corrugating and stretching rollers are described, Figs. 5-12 (not shown).

Title: Process for refining old rubber of all kinds and its application
IPC: C08J11/10
Filed: 1928-09-06
Abstract: 323,526. Potts, H. E., (Plauson, H.). Sept. 6, 1928. Utilizing waste rubber.-In a process for refining old rubber by producing dispersions in volatile solvents, suitable as lacquers, or vehicles for paints, the old rubber is heated in the solvent in the presence of a small amount of an organic anhydride or superoxide, or the peroxide of a metal of the alkali or alkaline earth groups, in order to reduce the strength of the rubber and render the compositions more paintable. Benzoyl peroxide, acetic or phthalic anhydride may be employed, and the heating is effected in an autoclave provided with stirrers, temperatures of 160‹ C. to 180‹ C. being suitable. Asbestos or other coarse or fibrous substances are separated by filtration, and fillers may be further removed by sedimentation or centrifuging. The dispersions may be used for impregnating paper, pulp, leather, &c. Colouring matter such as cinnabar, ochre, iron and silicate compounds, in colloidal form, and titanic acid, may be added, and for dark black tints asphalt, may be used. A higher gloss may be produced by adding copal, damar or other natural or artificial resins, tar oil, asphalt oil or like hydrocarbons. The addition of linseed or wood oil is also mentioned. The solvents may comprise low boiling hydrocarbons, such as benzene, in which case the pressure for effecting the process is obtained by the heating, or highboiling hydrocarbons such as heavy benzines, petroleum, turpentine, tar oil, in which case heating is effected under presure of a neutral gas such as nitrogen or carbon dioxide. Chlorinated hydrocarbons may be used as solvents. The Provisional Specification also mentions 100‹ C. to 120‹ C. as suitable temperatures, and describes the separation of rubber from the dispersions by evaporation of the solvent, treatment with gaseous acid, or electrodeposition.

Forcing apparatus for gases.-To withdraw the exhaust from an engine used on any vehicle such as an aeroplane, motor vehicle or boat, a body 1 is used shaped so that owing to its motion through the air a region of low pressure A, B is formed about the body; its shape is formed by generation of a chosen profile about an axis. The exhaust is led to this region either by pipes laid along the body or by passing out through holes 5 in the body. The Specification as open to public inspection under Sect. 91 (3) (a) also describes the use of a perforated aeroplane wing as the means used to extract the exhaust. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to vehicles having hydraulic transmissions and hydrauliccontrol systems for the hydraulic transmissions
IPC: F16H61/42
Filed: 1958-08-08
Abstract: 836,690. Hydraulic transmissions. MASCHINENFABRIK ESSLINGEN. Aug. 8, 1958 [Aug. 8, 1957], No. 25625/58. Class 69 (2). A vehicle transmission comprises a swash plate pump 1 connected to a motor 3, or motors, by lines 18, 19. The swash-plate is adjusted by pistons 4, 5 in cylinders 34, 35 connected, through a reversing valve 6 with a control cylinder 11 and a reservoir 12. The upper ends of cylinders 34, 35 are connected by passages 16, 17 to the lines 18, 19. In operation a motor driving the pump is started with the swash-plate in its neutral position, a foot pedal 10 is then depressed to move a controlpiston 8 against a spring 9 to draw liquid from the reservoir 12 through a non-return valve 13 into the control cylinder. On releasing pedal 10 the piston is urged by its spring to the right, expelling liquid from the cylinder 11 through valve 6 to cylinder 34 or 35 to tilt the swash-plate. Under heavy load conditions, such as hill climbing, the pressure in the high-pressure line 18 or 19 rises and acts on the associated piston 4 or 5 to reduce the tilt of the swashplate, spring 9 yielding to allow the movement. The maximum pressure is limited by a relief valve, 20 between lines- 18, 19. Valve 6 is actuable to reverse the angle of the swash-plate to reverse the motor 3, and has another position in which the lower ends of the cylinders 34, 35 are interconnected and the control cylinder is connected to the reservoir. In this position the pump swash-plate is returned to neutral by springs 14, 15 acting on the pistons 4, 5 and the motor 3 is thus braked. Valve 20 may be manually operable to short-circuit the motor when desired, and a valve 24 short-circuits the control cylinder 11 whenever an operator is not in position on the vehicle.

Air pipe lines 12 and 14 supply the housing 10. The pipe 16 and hood 20 are each free of internal partitions. A throttle slide 28 nests inside the pipe 16 and can be turned to control the air flow through the perforations 18. The slide 28 is connected at each end of the pipe to a partially toothed ring 30 which surrounds the pipe. The rings 30 mesh with pinions 32 connected to one another by a shaft 34. Thereby, during turning of the slide, twisting of the slide along its length is prevented. The slide may be coupled to an automatic adjustment mechanism. An alternative throttle slide is perforated and is adjustable axially (and optionally also circumferentially) of the pipe to align the perforations in the slide with perforations or unperforated parts of the pipe. The apparatus shown in the Figures can be used (a) by itself as a pipe outlet, (b) in a housing together with a heat exchanger and serve as a high pressure outlet or (c) in a housing as part of an induction air conditioning apparatus.
