Title: Method for dispensing flexible sheet material
IPC: B65D25/52
Filed: 1970-01-21
Abstract: 1299501 Dispenser for rolled web GEORGIAPACIFIC CORP 21 Jan 1970 [24 Jan 1969] 2922/70 Heading A4G [Also in Division B4] A dispenser for a roll of paper comprises a cover 92, Fig. 4 having end roll-viewing apertures, lockable at 110 and hingeable downwards at 108 on wallplate 20 and having upper supports 112 for roll 150, the protruding different sized core ends 158 of which are guided at 142 to be resiliently held in bearing recesses 138 with a braking spring 144 pressing on the roll end. Web 160 passes under and over guide means formed by pinch rollers 162, 164 sprung at 208 and around roller 174 to emerge at slot 104. On pulling the web, roller 174 turns with the web taut over longitudinal roller slot 176 and via gearing 226, 228, Fig.5 rotates roller 184 carrying longitudinal, radially curved serrated blade 182 which passes in and out of slot 176 to perforate the web transversely, the blade edge being curved so as to move with the paper at the point of contact and penetrate, e.g. stretchable crepe paper, and not slide over it. After a length of paper has been pulled, a pin 238 acts on cam 234 to rotate lever 230 and press timing suction caps 242, 244 together so that pin 238 abuts stop 236 on lever 230 and abruptly stops the rollers, the increased pull on the paper tearing the perforations. After a time interval the suction cups part under spring 256 and spring 262 rotates the rollers to project a grasping portion of web through slot 104. A partly used roll may be placed on supports 262 when a new roll is placed on the upper supports 112 and a double thickness web dispensed until the partly used roll is finished. A knurled wheel 240 on the cutter roller is rotated by hand at slot 280 against pawl 288 for threading the web through the guide means initially, the wheel 240 also being adjustable at 188 to allow the perforations to be inside or outside slot 104 when torn. Blade 182 may be helical and enter a helical slot 176 as in Fig. 23, the gearing between the rollers being such that slot 176 twists through e.g. 90 degrees compared with a 45 degree twist of the blade. The blade may be flat but hinged on its roller and have end lugs co-operating with cams on the ends of the slot roller whereby the blade edge is orientated in the direction of movement of its point of contact with the web.

Abstract: 122,519. Pollak, J. E., (Endless Chain Saw Co.). Feb. 19, 1918. Driving and like chains with separate jointpins.-Relates to pin joints or connexions of link belts, chains, chain saws, &c. The overlapping parts of the links are formed with alined openings a, the edges of the opening in each link being flared outwards from the opening in the other link. Arc-shaped bushings B, having grooves b shaped to correspond with the flared openings a, are inserted, and a. pin C is passed between the 'bushings. Very little upsetting or riveting of the pin is required to hold the parts together. To maintain the bushings in position circularly, sraall projections on one of the parts fit small recesses a<1> in the other part. The ends of the bushings are formed wedged-shaped, as shown at c, to prevent clogging with material. Fig. 1 shows the invention as employed in the construction of a chain saw. Fig. 4 shows a carrier link belt or chain in which the pin C' is headed, and is held in position by a nut, the head and nut forming covers for the spaces between the bushings B<1>, thus allowing these spaces to be used for containing lubricant. To render the joint more dustproof and prevent the escape of lubricant, the under faces of the head and nut may be concaved and spring washers be used therewith.

Title: Turbo machines, i.e. compressors and turbines
IPC: F01D5/22
Filed: 1958-01-29
Abstract: 844,896. Turbine and compressor-bladed rotors. UNITED AIRCRAFT CORPORATION. Jan. 29, 1958 [Feb. 11, 1957], No. 2952/58. Class 110 (3). In a turbine or compressor-blade rotor in which a plurality of blades is mounted around the periphery of the rotor disc with provision for limited movement of the blades with respect to the disc, inter-engaging projections and recesses are provided on the blade platforms to provide frictional damping of the limited movement. The blade 14 has a platform 20 and a root portion 36 which is received in the circumferential recess 40 formed between flanges 44, 46 at the periphery of the rotor disc 10. The blade is pivotally mounted on a bolt member 48 which passes through a bore 38 in the blade root and is in screwed engagement with the flange 46. The head of the bolt is received in an opening 54 in the flange 44 and bears against the blade root so that the blade root will tend to move to the right as seen in Fig. 4 as the bolt 48 is tightened. In the case of the adjacent blade 12 a washer 60 is disposed between the blade root 62 and the flange 46 so that the axial position of the blade 12 is fixed. The platform 20 of the blade 14 is formed with notches 22 and projections 28 which inter-engage with corresponding projections and notches 26, 24 on the platforms 18 of the adjacent blades. The interengaging faces of the projections 26, 28 are shown at 30, 32 and the pressure at the interengaging faces may be determined by the axial position of the bolt 48, this pressure acting to damp movement of. the blades about their pivot mountings. In a second embodiment, a spring washer is disposed between the head of the pivot bolt and the side of the blade root of alternate blades so that wear is taken up automatically. Alternatively some of the projections on the blade platforms may be inclined to planes normal to the rotor axis so that if there is relative motion between adjacent platforms about their respective pivot mountings, the friction between adjacent surfaces will vary.

Title: Improvements in or relating to the removal of acidic gases from gaseous mixtures
Inventor: THIRKELL HARRY
IPC: B01D53/14
Filed: 1965-01-23
Abstract: <PICT:1086453/C1/1> Acidic gases, e.g. CO2, H2S are removed from gaseous mixtures by passing the mixtures countercurrent to a solution of an alkanolamine, or an aqueous solution of a strong base and a weak organic acid in an absorber tower (1) containing at least two separate zones (2, 3) of packing material, e.g. contact rings, each zone provided with means for collecting liquor which has passed through the packed zone, and for recycling collected liquor, via a pump (8, 15), to the packed zone.  The means for collecting liquor may be either a collecting tray with a central duct (5) or the bottom reservoir.  Part of the spent liquor in the bottom reservoir passes, preferably after heat exchange (in 20) with regenerated liquor, to a regenerator tower (23) containing zones of packing material where it is stripped of the acid gases preferably at atmospheric pressure to 50 p.s.i.g., by solvent vapour, e.g. steam generated from the liquor in a reboiler (30), the gases and solvent vapour being condensed (at 46), separated (at 48) and the condensate returned as reflux (at 53) to the regenerated liquor in the regenerator tower. Regenerated liquor is then returned to the absorber tower.  The numerals refer to the Figure in which said liquor is returned via a pump 38 and a further water or air-cooled heat exchanger 40 where it is cooled to near ambient temperatures which may be e.g. 5-20 DEG  C. above the ambient temperature.  The last-mentioned pump and heat exchanger may be in reversed order.  The bulk of the acid gases may be removed by a first stage using hot K2CO3 solution, and the remaining 0.1-3% then being absorbed in the above process using a 5-25% aqueous solution of monoethanolamine, monoethanolamine in an organic solvent, or an aqueous solution of the potassium salt of an alkylamino-fatty acid.

Title: Valve mechanism
Inventor: MIRZA RIO NUSSERVAN
IPC: F16K13/02
Filed: 1955-02-02
Abstract: 782,851. Valves. FAIRCHILD ENGINE & AIRPLANE CORPORATION. Feb. 2, 1955, No. 3104/55. Class 135. A valve comprising a curved, pivotally mounted closure member 11 movable to a closed position in which it extends across a tube 10 and to an open position within a surrounding housing 13 coacts with an annular seat 20 and has means for pressing the closure member and seat together when the valve is closed and for relieving that pressure in response to opening movement of the valve. In the embodiment shown the closure member is of part-spherical form and the seat 20, carried by a bellows 24, is formed with passages 26 with which passages 27 in the closure member are brought into register when the valve is closed to give pressure fluid upstream of the valve access to the interior of the bellows. Movement of the closure member towards the open position interrupts this communication and vents the interior of the bellows. The seat 20 is slidable on a sealing ring 22 mounted in the tube 10 and is preferably of bronze or carbon. The housing 13 is welded to a tubular member 19 and screwed to an end fitting 15 which is welded to the tube 10. The seat 20 may be of spherical form to mate with the closure member or, alternatively, conical. The closure member is mounted on a spindle carried by roller bearings and is actuated by a crank arm. In a modification a piston and cylinder are employed in place of the bellows 24. In a further modification the seat, urged towards the closure member by upstream pressure acting within a bellows chamber, is eased therefrom by eccentrics on the valve spindle. At the same time, engagement between one of the eccentrics, which is knurled, and a knurled part of the seat causes partial rotation of the latter to provide a wiping action. It is stated that the pressure holding the seat in engagement with the closure member may alternatively be relieved by a valve which is tripped by cam mechanism or by a solenoid energized by a micro-switch in response to opening movement of the main valve.

Title: An automatic feed metering device for injection moulding machines, particularly for moulding soles and shoes
IPC: B29C45/46
Filed: 1966-01-25
Abstract: 1,131,122. Injection moulding machines. M.A.S. HYDRAULIC & VULCANIZING MACHINERY CO. S.r.l. 25 Jan., 1966 [9 Feb., 1965], No. 3331/66. Heading B5A. In an injection moulding machine comprising a plurality of moulds 4 mounted on a rotary turret 3, operation of a feed screw 7 is controlled by a switching device such as a microswitch 31 actuated by means such as limit stops 19a on the ends of measuring rods 19 extending radially from the periphery of a wheel member 18. After each injection the injection unit 1 is moved rearwardly by a cylinder 15, and a toothed wheel 20 mounted coaxially with wheel member 18 engages and is caused to rotate one increment clockwise by a pawl 21. The turret 3 is simultaneously rotated to bring an empty mould 4 opposite the injection nozzle 6. The measuring rods 19 are of such length that the correct quantity of material is fed into the injection unit for filling each mould. Feeding of rubber or similar material into the unit 5 is initiated by rotation of a feed screw 7. Rearward movement of a screw-carrying piston-rod 8 displaces a plate 29 carrying microswitches 30, 31 thereby sliding a roller 31b along the rod 19 as far as an enlarged end piece 19a thereof. When the roller 31b actuates the microswitch 31 on the plate 29 to stop rotation of the feed screw entry of oil into the cylinder 15 causes forward motion of the injection unit, until its nozzle 6 engages the mould 4. The increasing pressure caused by this actuates a pressure gauge (not shown) in the pressure conduit of the cylinder 15 to commence injection. The forward movement of the feed screw 7 and rod 8 correspondingly moves the plate 29, with the microswitches 30, 31 the former then contacting an adjustable screw (30a) on the injection unit 1 to cause rearward movement thereof once more. Modifications.-If the piston 9 has a long stroke the measuring rods 118 are kept within reasonable size by using the pivoted linkage (104, 107) seen in Fig. 5 (not shown). The rod (104) is pivoted at (105) to a piston-rod (102) of the piston 9. The rod (107) is pivoted at (108) to a fixed plate (110) and, intermediate its ends, to a rod 113. The rod (113) is connected to a slide (114) mounted on a guide (115) on the machine frame. The guide 115 carries a microswitch (116) which engages with adjustable limit stops (117) on the rods (118). In a further modification (not shown) photo-electric cells may be used in place of the microswitches.
