Title: Improvements in or relating to devices for metering particulate solid
Inventor: BILLINGTON WILLIAM PETER
IPC: G01G11/00
Filed: 1966-11-04
Abstract: 1,212,973. Weighing apparatus. NATIONAL RESEARCH DEVELOPMENT CORP. Jan. 3, 1968 [Nov. 4, 1966], No.49609/66. Heading G1W. A metering device for particulate material comprises a conveyer 13 which is pivotally supported at one end on a framework 1 and which is acted upon by a spring 35 in the region of its other end, the conveyer 13 being arranged to receive material adjacent its pivotal support and convey the material to its other end where the material is discharged so that the angle of inclination of the conveyer 13 against the action of the spring 35 is indicative of the weight of material conveyed by the conveyer, the conveyer being connected to a totalizing device 61. As shown, the conveyer 13 comprises an endless belt 15 mounted on pulleys 17, 27 which are journalled on a beam 11. The beam 11 which carries an electric motor 25 arranged to drive the pulley 17 through a gear-box 23 is pivotally mounted by stub shafts 9 on the framework 1 directly below a hopper 49 having an outlet 51 through which material is fed to the conveyer 13. The conveyer 13 is connected to a hydraulic dash-pot 45 and is provided with a pointer 39 which is movable over a stationary scale 41 to indicate the instantaneous loads on the conveyer. The total amount of material conveyed by the conveyer 13 is indicated by the totalizing device 61 which comprises an eccentric cam 63 attached to the pulley 27 so as to be rotated at a speed proportional to that of the conveyer belt 15 and a cam follower 65 which is arranged in each cyde of the cam 63 to abut successively a stop 75 and then a portion of the cam 63 to be driven thereby, the magnitude of the portion being proportional to the instantaneous load on the conveyer belt 15. The cam follower 65 is connected to a revolution counter 67.

Title: Process and apparatus for the impregnation of non-woven fabrics

Abstract: 1364506 Impregnating non-woven fabrics CARL FREUDENBERG 29 Oct 1971 [29 Oct 1970] 50386/71 Headings D1L and D1R [Also in Division F2] In a process for impregnating non-woven fabrics a liquid binder composition 6 is supplied to the nip of a pair of rollers 2, 3 at least one of which is a smooth roller which carries on its curved surface one or more detachably mounted strips from which sharp teeth project. The non-woven fleece 4 may be fed to roller nip by a conveyer belt 5 or by a roller positioned above the nip [Fig. 6, not shown]. In the latter case both rollers may have a toothed profile and the binder composition is fed to both sides of the fleece. The toothed roller preferably has a single narrow, ratchet-toothed, stainless steel band coiled round its curved surface so that an edge of each coil is in contact with an edge of an adjacent coil of the strip. The liquid binder composition may be a solution, dispersion or emulsion and is preferably a fluid foamed composition. In an Example a mixture of cardable fibres composed of wool, human hair, camel hair cotton and rayon or viscose staple was made with the help of cards into thin webs, six of which were then superimposed with a crosslapper and pressed between hot rollers. The resultant fleece was fed between the nip of the apparatus illustrated and impregnated with an aqueous-foamed binder composition containing a butadiene/styrene copolymer, sodium isobutyl naphthalene sulphonate, zinc oxide, sulphur or vulcanisation accelerator and an antioxidant. After impregnation the web was dried at a temperature of 80-120‹C and then vulcanised at a temperature of 120-140‹C before being calendered and washed.

Abstract: 1,148,206. Gas turbine plant; stator vanes. GENERAL ELECTRIC CO. Nov. 11, 1966 [March 4, 1966], No. 50680/66. Headings F1G and F1T. The compressor inlet guide vanes, or other guide vanes, of a gas turbine engine are heated to prevent icing by hot air supplied to the interior of each vane from a manifold 52 through ducts 28 and directed to passages 42, 44 adjacent the leading and trailing edges 36, 38 by a corrugated stiffening insert 40. The vane edges are inclined with respect to the conduits 46 formed by the corrugations so that the conduits open one after the other, as at 48, into the passages 42 or 44. A member 50 blocks off the middle conduits 46 and perforated baffles 54 direct the air from ducts 28 to those unblocked, a heat insulating sleeve 56 preventing hot spots on the vane surface adjacent the baffles. Ducts 28 are of steel and the vane is of titanium having a lower coefficient of expansion such that the ducts, which are a loose fit in the vane cap 26 in the cold condition, expand into sealing engagement with the cap when hot. The hot air leaves the vane through outlet 58 and conduit 60. In a modification, the inclination of the conduits 46 with respect to the vane edges is effected by canting the insert 40.

The ship has a carriage 10 running on a horizontal track at the top of the walls of the hold and driven therealong by motor driven pinions 10a engaging racks 9. The carriage 10 has a turntable 13 mounting a transfer belt conveyer 12 adjustable heightwise by an expansion mechanism 30. The transfer conveyer 12 leads to a main belt conveyer 17 which can have its inclination varied by an expansion arm 15 acting on its base 16 which is pivoted to the turntable at 14. The bottom of the base 16 has a fixed arm 18 to which the base 20 of an auxiliary conveyer 21 is pivoted at 28 and is adjustable by an expansion arm 19. By adjusting the turntable 13 and the inclination of the belts 17, 21 any paint in the hold can be reached by the end of the conveyer 21. In loading the ship the ramp 8a of the conveyer 8 rises above the conveyer 12 to allow the bags to drop thereon while similarly the conveyer 12 is above the end of the conveyer 17. For unloading these relative elevations are reversed.

Fig. 1 shows the left half of the cylinder with the piston descending ' and 'the exhaust valve 4 opened, exhaust taking place through all the cylinder ports 10 and 11 into the manifold 9 The exhaust valve 4 is closed later and the inlet valve, 3 opened as shown in Fig. 2, which represents the right half of the cylinder, with the piston ascending. Scavenging-air is thus admitted from the manifold 8 through the ports 10 and sweeps the remaining gases through the ports 11 and upwards into the exhaust manifold 9 through transfer ports (not shown) provided in the horizontal portions of each of the rightangled valves 3 and 4, these ports being controlled by a hand-adjusted throttle segment 5. The piston then closes the exhaust ports 11, and supercharging occurs through the inlet ports 10. The two end air ports 10 at each side of the cylinder are inclined, as shown, away from the eyhaust ports to prevent loss of charging-air.
