Title: Actuator unit
IPC: F15B13/16
Filed: 1973-03-22
Abstract: 1355029 Fluid-pressure servomotor systems GENERAL SIGNAL CORP 22 March 1973 [30 June 1970] 13825/73 Heading G3P An actuator unit comprises a piston and cylinder air motor 12 controlled by a servo-valve 13 positioned by an electric stepping motor 15, correspondence being provided by pivoted lever feedback linkage 16. Electric motor 15 drives an output shaft 58 to which is secured a torque transmitting sleeve 59 having a longitudinal slot 62 slidably engaging a radial pin 63 on the end of a rod 48. The latter is threaded into a non-rotatable bushing 52 and engages servo-valve spool 32 so that rotation of motor 15 causes longitudinal movement of rod 48 to move spool 32 within a ported sleeve 28 and control the flow of operating air from inlet 43 to sides 23 or 24 of piston 22. Feedback linkage 16 comprises a bell-crank 73 pivoted at 74 and having an arm 75 bearing via pin 76 against the upper face of washer 77 attached to rod 27 of piston 22. The other arm 81 of crank 73 carries a contact 82 whose nose bears against arm 83 of a second bell-crank 84 pivoted at 86. Crank 84 has a pair of parallel arms 88, (87) Fig.4 (not shown), the latter carrying a pin 91 bearing against the upper surface of bushing 52. The bushing is longitudinally slidable within bore 29 of the valve housing but is prevented from rotating by pin 53. A spring 93 urges bushing 52 into engagement with pin 91. The feedback linkage 16 thus acts to move bushing 52 and rod 48 longitudinally to restore spool 32 to its neutral position after appropriate movement of piston 22. The gain of linkage 16 can be adjusted by loosening lock screw 97 and rotating lead screw 95 to move contact 82 up or down crank arm 81 and thus vary the ratio of angular movement of bell-cranks 73, 84. Limit stops 68, 69 are provided at opposite ends of torque sleeve 59. The exterior of the latter is threaded and carries a nut 64 which is prevented from rotating by a plate 65 secured thereto and extending into a guide slot in fixed wall 56. Thus rotation of sleeve 59 causes movement of nut 64 therealong until contact is made with stops 68 or 69, which positions correspond to maximum displacement of piston 22 from its central position. Initial adjustment of ported sleeve 28 within the valve housing can be effected by loosening lock nut 31 and rotating sleeve 28 so as to screw it further in or out of bore 29.

Filed: 1925-05-28
Abstract: 240,789. International Nickel Co., (Assignees of Stanley, R. C.). Sept. 30, 1924, [Convention date]. Matte processes for copper and nickel.-Nickel and copper are separated from mattes or other material by a process which consists in subjecting the material to a furnace treatment, separating the product into copper tops and nickel bottoms, and blowing the tops and bottoms in converters. The material is smelted in a cupola furnace with an alkali sulphide, and the molten sulphides are taken from a fore-hearth to a separating furnace or to large pots. The bottoms may be resmelted, if desired, the copper tops resulting therefrom being returned to the first smelting cupola. The nickel bottoms are treated in a converter lined with basic or neutral material, and the metallic nickel is then refined electrolytically. Precious metals are recovered in the slimes from the electrolytic cells, and the cell liquor is circulated through cementing tanks to remove copper and iron. Specification 138,600 is referred to.

Abstract: 915,584. Making bags. WINDMOLLER. A., and GENNERICH, M. April 21, 1960 [May 8, 1959], No. 14078/60. Class 94(2). A multi-ply bag with a plastic-coated inner ply and coated cover slips as the inwardly exposed stepped bag corners is made by a process wherein the web 1, having a plastic coating 2, from which the inner ply is formed, before being combined with the other webs 24, 25, 27 is provided on its uncoated side with adhesive areas 8 on which patches 16 are stuck in such position that they extend beyond weakening lines 9, 26, which enable the web to be separated into lengths, so that cover slips are formed which project beyond the edge of the inner ply and cover steps 23, 26, in the other plies, these steps subsequently forming the inwardly exposed stepped corner folds. The patches 16 are cut from narrow coated webs 10 drawn off a supply reel (not shown) and are fed between the webs 1 and 24 in such a manner that they stick with their coated sides 11, by one end, to the adhesive coating 8 on the inner web 1 and extend beyond the weakening lines 9 so that they project beyond the edge of the inner ply 1 and cover the overlaps of the other plies in the regions where the corner folds are to be formed. The width of the patches is equal to or somewhat greater than double the distance of longitudinal incisions 28 in the web from fold lines 29 for the sides of the bag. The incisions 28 provide steps in the edges of the webs 1, 27 and are positioned so that the resulting tube sections are visibly stepped on the outside of one half of their circumference and on the inside of the other half. The cut patches are brought under the web 1 by a roller-and-belt system so that they stick to the adhesive coatings 8, projecting beyond the lines 9 in the direction of movement of the web. The rollers and belts are driven from a shaft 33 through bevel gearing. The web 10 is cut by knives 14 and grooves 15, on cylinders 42, 43 respectively which are driven through gearing from a shaft 59. The adhesive is applied by rollers 4, 5 which, with scraper rollers 6, are driven through gearing from the shaft 39 of the knife cylinder. An epicyclic gear system controlled by a hand wheel 51, enables the adhesive-applying and cutting mechanisms to be adjusted, to vary the position of the patches with relation to the weakening lines of the inner web, while the machine is running.
