Title: Improvements to automatic adjusting devices for brake linkage systems
Inventor: FEUILLY JULES EMILE JOSEPH
IPC: B61H15/00
Filed: 1961-12-16
Abstract: 930,576. Automatic brake clearance adjusters. SVENSKA A.B. BROMSREGULATOR. Dec. 16, 1961, No. 45178/61. Class 103 (1). A brake clearance adjuster, particularly for use in railway vehicles, comprises a nut 31 and screw 34, the nut being freely rotatable on the reversible screw-thread in the direction of unscrewing to increase the clearance and being positively rotated in the direction of screwing-up to take up clearance. The nut 31 is rotated by an adjuster casing 35 set in oscillation by a rocking angle lever 60 which traverses a slideway piece 63 under the thrust of the brake cylinder, the connection between the casing 35 and the lever 60 being a hinged rod 40. The lever 60 and slideway piece 63 are so designed that one oscillation of the casing is effected during both the brake application and release strokes. The lever 60 is pivotally mounted on a pin 8, a roller of which slides in a slot 62 of the slideway piece 63. Lever 60 possesses three thrust faces which cooperate with rollers 69, adjustable in position along a slot, and 70 of the slideway piece 63. A coupling sleeve connected to nut 31 and a circlip 53 of casing 35 are adapted to frictionally engage a drive ring 50 in part of the operative cycle of the adjuster. The drive ring 50 is actuated by a coiled spring 51 attached at one end to the casing 35 by friction and at the other to the drive ring 50 allowing free rotation of the latter in the direction of unscrewing. A compression spring 46 is positioned between a shoulder of a hollow shaft 48 connected to sleeve 52 and a thrust bearing acting against the drive ring 50. A guide sleeve pivotally connected to a beam lever 7 possesses a thread 44 which co-operates with a thread 43 of the casing. A motion discriminator in the form of a butt coiled spring 88 in frictional contact within sleeve 90 of guide sleeve 5, engages in an opening 86 of drive ring 50 so that rotation in the unscrewing direction of the nut and screw is prevented. If the clearante is too small, during the brake application all components of the adjuster become stationary in translation except for guide sleeve 5. Thread 44 engages thread 43, drive ring 50 being drawn out of contact with coupling sleeve 52 by circlip 53 effecting the unscrewing of the nut and screw by virtue of their reversibility and the braking force. The unscrewing continues until nut 49 frictionally engages ring 47. If the clearance is too large, however, on release of the brakes, the parts will move towards their inoperative positions until drive ring 50 frictionally engages coupling sleeve 52. The casing then performs the screwing up portion of its oscillation which through spring 51 is communicated to drive ring 50 and thence to the nut 31.

Title: Tobacco smoke filter element
IPC: A24D3/04
Filed: 1971-10-05
Abstract: 1336465 Tobacco smoke filters EASTMAN KODAK CO 5 Oct 1971 [5 Oct 1970 5 April 1971 9 Aug 1971] 46312/71 Heading A2C A tobacco smoke filter element comprises a porous body having an outer side wall and end walls and first and second indentations extending from the side wall into the body, the arrangement being such that in use a pressure differential is created between the indentations so that a portion of the smoke flows at a reduced velocity in a generally diagonal direction from the area of one indentation towards the other indentation. The element, which is enclosed in an outer wrap, may be made of any suitable filter material such as creped paper or a tow of crimped themoplastic fibres, e.g. fibres of polyolefin, polyester, cellulose ester, or mixtures and the indentations may be made by heat and/or pressure or by a cutting operation. The two indentations 11, 13, Fig. 1, are in the form of elongate grooves differentially spaced from the ends so that if, e.g. smoke is flowing from left to right the pressure in the groove 13 will have a higher value than that in the groove towards 11. The two grooves may alternatively be directly opposed to each other and the two ends of the filter cut obliquely. In modifications, each groove is replaced by a series of parallel indentations or by a cut-away portion in the form of a segment of a cylinder. Fig. 11 shows a further embodiment in which the indentations are in the form of grooves 31, 33 deepening progressively from points on the outer surface of the filter towards the ends. In modifications of this embodiment, the grooves have rounded bottoms, one of the grooves terminates short of the end, and two additional grooves extend from one end a short way along the filter. In a further embodiment, a continuous rod is passed through a tube 136, Fig. 27, and pierced by heated pins 144 guided by holes 142 in the tube, the rod subsequently being severed at the dotted lines 146. The piercing may alternatively be effected by hollow pins through which hot air is passed or by hollow or porous inserts through which a solvent is injected. Also, inserts that will disappear after the filter has been firmed, e.g. of ice, may be used.

Filed: 1961-12-29
Abstract: 962,482. Tipping casks. HOOVER BALL & BEARING CO. Dec. 29, 1961 [Dec. 29, 1960], No. 46772/61. Heading B8E. A device for tilting containers, e.g. rectangular bins, comprises a fixed frame 44 and a subframe 34 pivotally mounted on the frame at 38 and includes a clamp means 60, 62 which engages the top of the bin to hold it in place on the sub-frame during tipping. In one embodiment a bin 20 has legs 22 which fit between converging side members 32 of the sub-frame 34. Vertical reciprocation of a rack 52 by a fluid-operated piston-and-cylinder assembly 48 causes rotation of the sub-frame 34. The rack 52 is pressed against a pinion 54 on the sub-frame by a roller 56 to ensure proper engagement. The sub-frame is first rotated through about 15 degrees, this causing the bin to slide across the base of the sub-frame so as to abut against rollers 66. A clamping bar 64 is then lowered by piston and cylinder assemblies 60, 62 to clamp the bin in this position. The sub-frame is then rotated further to a total of 135 degrees, i.e. the position shown in full lines in Fig. 4. The clamp bar 64 is then released allowing the bin to run down the rollers 66 and engage its dispensing aperture 26 with a hopper 78 as indicated in broken lines in Fig. 4. A dolly 69 is roller mounted on a pair of tracks 68. This dolly supports a mid-portion of a side of the bin and thus prevents " bellying out " of that side. In a modified form of apparatus (Fig. 8) the clamp comprises a dispensing spout 96 which fits on to the dispensing aperture of the bin when it is clamped. The spout has a face 102 which fits on to a hopper 104 when the bin is tipped. In a further modification (Fig. 11, not shown) in which it is not necessary for the spout to form a sealing engagement with the hopper the spout has a self-closing gate which opens after the bin has been tilted. Specifications 674,091 and 962,481 are referred to.
