Title: Process for the recovery of synthetic polymer fibrils
IPC: D01F6/04
Filed: 1974-03-01
Abstract: 1441883 Producing fibrils SOLVAY & CIE 1 March 1974 [2 March 1973] 9338/74 Heading B5B [Also in Division B1] A suspension in liquid of synthetic polymer fibrils is formed in a closed vessel 1 by supplying a polymer/organic solvent through a pipe 3 to a pressure-release spinneret 5 where a fibre is formed by vaporization of the solvent, is shredded by a jet of fluid (e.g. further solvent) from a pipe 4, and is conducted with the solvent vapour by a pipe 7 below the surface of a suspending liquid (e.g. water) which is thereby agitated. There may also be a mechanical stirrer 18. The suspension is withdrawn at 20; part may be recycled through an outlet 21. Solvent vapour is discharged at 9 and the top of the vessel has inlets (10, 13, Fig. 2, not shown) for suspending liquid and recycled suspension. There may also be inlets (11, 12) for additional solvent vapour and inert gas. In a modification (Fig. 3, not shown) the suspending liquid is supplied by an annular array of spray nozzles in the fibril inlet, inclined to promote the forward movement of the fibrils. There is a steam jacket 2, the temperature of the apparatus being maintained above that at which the solvent is a vapour but below the boiling point of the suspensing liquid. The pressure in the chamber is controlled to be slightly above atmospheric and means are provided to prevent excessive rise, or fall below atmospheric. The level of the suspending liquid is maintained constant by varying the rate of supply, discharge or recycle. In an example the polymer is polyethylene and the solvent is hexane, the apparatus being maintained at 85 C.

IPC: B65G53/06
Filed: 1969-02-21
Abstract: 1,246,546. Feeding apparatus. NATIONAL RESEARCH DEVELOPMENT CORP. 16 Feb., 1970 [21 Feb., 1969], No. 9514/69. Heading AIM. [Also in Divisions B8 and G1] A metering device for diverting a predetermined quantity of solid material from the conveying airstream of a pneumatic conveyer comprises a perforate or mesh flap 9 interposable into the airstream to divert solid material into a container 11 resiliently suspended from the conveyer conduit 1, and means responsive to a predetermined downward movement of the container 11 due to the accumulation therein of diverted material to initiate withdrawal of the flap 9 from the airstream. A support frame 4 is clamped to the ends of the conduits 1 and a valve body 8 containing the flap 9 is connected by flexible ducts 5 to the conduits 1. The container 11 is rigidly connected to the valve body 8 and is suspended from the frame 4 by tension springs 19 hanging from levers 18 pivoted to the frame 4. A selector lever 23 moving over a dial 21 acts via a cam (24) (Fig. 1, not shown) on the levers 18 to adjust the spring preloading, and hence the load at which the container and the valve body move downwards from stops 25 on the frame 4. A bellcrank lever 30 on the pivot shaft of the flap 9 engages a stop 34 and a reset arm 32 on the frame 4. At the predetermined load, the valve body and container have moved downwards far enough for the lever 30 to clear the stop 34 and 32, allowing the flap 9 to move by gravity and/or spring bias to a position out of the airstream and closing the branch opening in the valve body. The container 11 has a counterbalanced bottom door 14 normally held closed by a latch 17 which is releasable manually or by a timer.  In an animal feeding system, a series of metering devices in a pneumatic conveyer circuit fill their containers 11 in succession when the system is operated, the containers being subsequently emptied into food troughs.

Title: Improved mechanism for transforming reciprocating movement into rotary movement, and conversely
IPC: F16H19/04
Filed: 1936-04-01
Abstract: 468,652. Gearing for converting rotary into reciprocating motion and vice versa. VARCIN, A. L. April 1, 1936, No. 9700. Convention date, April 2, 1935. [Class 80 (i)] In the mechanism described in Specification 270,562, [Class 80 (i)], the cams for facilitating reversal at the ends of the stroke are so shaped that the last tooth of the mutilated pinion 7 to engage a rack 1 comes out of contact with the corresponding tooth of the rack before sliding begins. As shown in Fig. 2, the profile 17 of the cam lies between the archimedean spiral, eghg<1>e<1> which would produce the same movement of the rack as would be produced by a continuously - toothed pinion and the curve egig<1>e<1> which would produce the same movement of the rack as would be produced by the last tooth p<1> if it slid off the last tooth c<1> of the racks. As shown at p<3>, c<30>. The portions eg, g<1>e<1> of the profile 17 belong to the spiral, since up to the position p<2>, c<2>, the gear engagement is perfect. If gear engagement continued, the rack tooth would reach c<6>, but the cam portion g j brings it to an intermediate position c<3> in which it clears the pinion tooth at p<3>. The part j, f, j<1> of the cam is designed to produce a constant acceleration, or may be of sinusoidal form to give zero acceleration at dead centre, or the cam may produce zero, constant and variable accelerations at different parts of its stroke. The cam may be unsymmetrical about OX. The invention is applicable to the form disclosed in Fig. 3 of Specification 270,562, in which two pinions are employed. The end teeth of the pinion may be bevelled as shown at t so that a flatter curve egkg<1>e<1> may be employed. The invention may be applied to engines, the piston or pistons being secured to the racks.
