Abstract: 443,395. Machines for working land. FOWLER & CO. (LEEDS), Ltd., J., and BIRRELL, E., Steam Plough & Locomotive Works, Leeds. Feb. 7, 1935, No. 3995. [Class 6 (i)] In rotary tilling-machines in which the tilling-tools are secured on rings mounted to rotate about axes inclined to the vertical and sweep through the soil in cycloidal paths with the rear part of the sweep at a lower depth than the front part, the stem of each tool carries a share and a separate deflecting plate secured above the share and forming a continuation of it, the share and plate projecting beyond the sides of the stem. The wide upper part of each tool stem a has two webs a<3>, a<4> adapted, respectively, to bear against the outside and inside of the ring b and provided with offsets or stops a<5>, a<6> to fit against the underside of. the ring to relieve the fastening bolts c of upward forces.

A tapered plug a<2> at the lower end of the stem may be inclined forward and the share d may have a tapered socket which fits on any one of the plugs, being secured by a wooden peg. The share may be slightly curved so that its lower end is advanced. This end edge may be dihedral, or it may be straight and either at right angles to the side edges or inclined to right or left. The lateral edges may be in planes tangent to cylinders co-axial with the ring. A share may be in two parts d<6>, d<10>, Fig. 18, connected to one another by tongue-and-socket and a wooden peg, the upper part being fastened to the stem by a bolt or stud d'. The deflecting plate f fits any stem and is secured by bolts or studs f<1>. It may be formed with two oppositely inclined faces f<2> or with a face swept to the right or left.

Filed: 1972-01-28
Abstract: 1385522 Blow-moulding oriented, handled containers OWENS-ILLINOIS Inc 28 Jan 1972 [28 Jan 1971] 4129/72 Heading B5A A molecularly oriented container having an integrally blown handle is blow-moulded from an extruded tube of thermoplastic by firstly blow-moulding the tube in a preform blow mould having an interior cavity which more closely resembles the final container than does the extruded tube, cooling the preform and then blowing in a final blow-mould having portions to pinch out the hand-hole. As shown in Fig. 1, parison 22 is extruded from extruder 20 and received in preform blow-mould 30 which is tilted on platens 23 by cylinder 33 for more favourable material distribution and severed by knife 29. The left hand platens 23 are retracted by cylinder 25 to the blowing position while the right hand platens 23 are extended to the receiving position. Parison 22 is blow-moulded in mould parts 30 by nozzle 70 to preform 48 while previously formed preform 48 is blowmoulded to final form 65 in blow-mould 31. After blowing, platens 23 are moved apart, preform 48 being retained on nozzle 70 and product 65 on nozzle 71, the nozzles 70, 71 then being retracted to strip product 65 and position preform 48 for subsequent receipt in mould parts 31. The platens 23 are then moved back to the Fig. 1 position so that mould parts 30 receive a fresh parison and mould parts 31 the preform 48. The preform blow mould 30 forms a portion of the handle area such that it is received in the final blow-mould 31 and the handhole formed by surfaces (56, Fig. 7, not shown) thereof without formation of external flash. The preform blow-mould 30 may have heating elements (46, 47, Figs. 2, 3, not shown) to maintain the preform 48 at a suitable temperature for orientation. The flash formed by surfaces (56) in the hand-hole of the blow-mould 31 may be removed by plunger (60, 61, Fig. 7, not shown).

[Also in Group VIII] In the operation of a machine for fracturing the coating on a web of paper to prevent curling of the paper, the web 8 passes from the reel 5 around a pair of jockey rolls 9 and 10 linked by a lever 11, over a pair of compensating rolls 12 and 13 the latter being adjustable relative to the framework, round a pair of adjustable rolls as at 14, over the outer projecting edges of fracturing blades 26, 27 secured to two sides of a triangular angle-iron frame 25 the third side of which is adjustably hinged to the framework, past a lever-mounted adjustable roll 15, around a guide roll 16, between the nip of a pair of driven draw rolls 17, 18, the second being rubbercovered, around a series of guide rolls 19-22 some of which are spring-loaded, then to the reel 7 which may be rotated by a friction drive indicated by a disc 23. In order to prevent damage to the paper there is provided a suction table comprising an endless conveyor band 28, running at a speed slightly in excess of the rate of travel of the web, and a suction box 30 having a foraminous wall 32 and connecting through a conduit 33 with a fan 34 the suction effect of which holds the web in frictional contact with the upper run 29 so that the two will run in company thus equalising the fracturing effort at the two blades.

Abstract: 562,677. Shock-absorbers. AUTOMOTIVE PRODUCTS CO., Ltd., and DOWN, C. R. March 30, 1942, No. 4231. [Class 108 (iii)] An oleo-pneumatic shock-absorber has a plunger with coaxial portions 19, 21 of large and small crosssection sliding respectively in fluid-tight seals at opposite ends of a cylinder 12, thus forming a collapsable annular chamber 35 which is filled with damping liquid extending also to a chamber 31 inside the plunger. The collar 20 uniting the two sections of the plunger has passages 34 allowing relatively free flow of the liquid to the chamber 31, but only slow flow through damping passages 40 in an annular valve 38 of cupped cross-section. A piston 26 in the plunger separates the liquid from the air chamber 32 and has a hollow closed stem 28 with a flared perforated easy fitting guide 30 sliding in the smaller bore of the plunger. Inlets 36 and 33 admit liquid and pressure air. In a modified form, the recoil damping chamber 45, Fig. 2, is arranged outside the plunger by having the collar 20 extended to form a piston in the cylinder 12 which is then relatively wider and the damping passages and valve are between the plunger and cylinder.

Class 100(1) [Also in Group XXIV]  A web winding apparatus of the kind which comprises a friction clutch in the drive for a winding shaft which can be slipped to a variable degree under the control of means responsive to the web tension, has a pair of coaxially mounted friction discs 4, 5, the disc 4 being secured to the winding shaft 1 so as to drive this shaft and the disc 5 being adapted to be driven from an external source a movable guide roller 11 for application against the web a rotatable shafts 14, supporting this roller, a weight 34 mounted on a rod 33 extending from this shaft, such that the roller can swing about' the axis of the latter under the influence of the weight, and a link 29 and lever 18 for converting swinging movements of the guide roller into forces applied axially on the element 5, so as to vary the pressure between the discs 4 and 5. The disc 5 is mounted on an extension 1a of the shaft 1. A chain sprocket 8 is secured by a cap 6 and bolts 7 to a boss 5a mounted on an anti-friction bearing 9. An endless driving chain, not shown, passes around the sprocket 8. A friction lining 10 is interposed between the discs 4 and 5. A screw 15, threaded through one arm 18a of the two armed lever 18, engages a member 16 in the cap 6 to vary the pressure between the discs 4 and 5. Variations in web tension, detected by the roller 11, cause rotation of the shaft 14 and so rocking of the lever 18 about its pivot 19 through the link 19. arms 28, 25, and a link 23, thus varying the slip of the clutch. The effectiveness of the weight 34 may be varied by adjustment along the rod 33. Specification 710,263 is referred to and Specification 680,331 is referred to in the Provisional Specification.
