Abstract: 1291446 Centrifugal separators; centrifugal strainers PENNWALT CORP 15 Oct 1969 [28 Oct 1968] 50678/69 Headings B2P and B1D In a centrifuge of the type described in Specification 1,183,858, the means for detecting the level of solids in the centrifuge bowl 22 comprises channel-shaped ring 60 mounted on top of the bowl and provided in its floor with equi-spaced threaded openings in which are secured solids-level sensing tubes 62 which extend outwardly into the bowl to the maximum desired solids level A. Control liquid, which may be water under pressure or clarified liquid from an effluent tank 46 connected to the centrifuge is fed continuously or intermittently to the interior of the ring 60 through a line 66 and via a flow control valve 67 and sensing means 68 responsive to the build up of control liquid in the ring 60 upon obstruction of the outlet openings 63 of the tubes 62 by accumulated solids. The sensing means 68 may be a pressure-responsive switch sensitive to the build up of pressure in the flow of control liquid; a flow-responsive switch sensitive to the decrease in the flow rate of the control liquid; or a velocity-responsive switch responsive to the decrease in the velocity of the control liquid. The switch 68 is electrically connected to the solenoid-operated feed valve 36 and to the drive means 56 for the skimmer 50 and, optionally, to the control valve 67 which would then be solenoidoperated and would be shut and opened at the same time as the valve 36. The build-up of control liquid in the ring 60 may alternatively be sensed by a skimmer tube connected to a pressure-responsive switch similar to the switch 68. Both the pressure-responsive switch and the depth at which the line 66 opens into the ring 60 may be adjustable to vary the depth of solids accumulation before actuation of discharge. Instead of the clarified liquid discharging over the lip 32 at the upper end of the bowl, it may do so through perforations in the wall 57. In this case the skimmer 50 may be omitted and a radially movable knife or peeler may be substituted to discharge the accumulated solids.

Abstract: 1360325 Bi-stable circuits HITACHI Ltd 8 Nov 1972 [19 Nov 1971] 51527/72 Heading H3T A cross-coupled F.E.T. bi-stable 3, 4 is set by: turning off further F.E.T.'s 6, 7 to isolate the sources of F.E.T.'s 3, 4 from earth; turning on a F.E.T. 9 to complete the cross-coupling; and earthing F.E.T. 3 source through a F.E.T. 5, or not, in response to Vin. If V in  turns on F.E.T. 5, then F.E.T. 3 being held on by load F.E.T. 2 and -Vdd, capacitor C2 is earthed through F.E.T.'s 3, 5. When F.E.T.'s 6, 7 then turn on again, and F.E.T. 9 turns off (CP x  and CP 1  being complementary), F.E.T. r is held off by the charge on C2, and so the output B, gated by F.E.T. 8 and CP2 to C3, is negative. A zero output is obtained correspondingly from an opposite Vin. Load F.E.T.'s 1, 2 may be gated on by CP1 to conserve power, in this case a further F.E.T. (18, Fig. 2, not shown) being necessary in parallel with F.E.T. 2 and gated by CP2, to ensure that during readout in CP2 time, charge-sharing between C3 and C1 at F.E.T. 3 gate cannot occur which would result in a reduced voltage output at 6. In a set-reset version of the bi-stable, (Fig. 3, not shown), an extra F.E.T. 25 is included in parallel with F.E.T. 7, the set, reset inputs going to F.E.T.'s 5, 25 respectively.

Abstract: <PICT:1029360/C4-C5/1> <PICT:1029360/C4-C5/2> <PICT:1029360/C4-C5/3> A process for extracting oil from a homogenized cake of ground olives by means of a horizontal centrifugal extractor having two coaxial bowls comprises the steps of feeding the cake by small portions to the inlet of the extractor, combing the fibres contained in each small portion at its entrance into the extractor, directing the combed fibres into a centrifuging area of the extractor and submitting the fibres and other residues to a heating operation.  The extractor, Fig. 1, comprises an outer bowl 4 and an inner bowl 5 having helical conveying blades 6 on its outer surface, the bowls being driven in the same direction and at adjustable differential speeds through a device 2.  A partitioned casing 7 surrounding the bowls is provided with outlets 8, 9, 10 serving to evacuate respectively residues (including the fibres), aqueous juices and oil obtained in the course of the extracting process. The cake is fed via a nozzle 11 through a conduit 12 and is deflected radially into channels 22, Fig. 3, in an end plate 15 in the inner bowl 5.  The channels are provided with toothed surfaces 23 for combing the fibres and lead into the space between the bowls into which space water has been previously introduced via the conduit 12, a conduit 13 provided with end perforations 14 and two conduits 17.  Under the action of centrifugal force the oil and aqueous juices are separated in the part of the annular space between the bowls bounded by the cylindrical part of the outer bowl and accumulate in two layers between the helical blades 6. The oil is led by means of two grooves 24, Fig. 4, at the bottom of the blades 6 into a channel 18 bounded by a plate 19 serving to prevent mixing of the separated oil and aqueous juices, the grooves 24 being helically cut into the bowl 5 in a direction opposite to the direction of rotation of the bowl in order to exert a pumping effect.  From the channel 18, the oil is evacuated via similarly helically wound tubes 25 into an annular constriction 30 in an end plate 151 for the bowl and then via orifices in the plate against a deflector 32 and a froth-preventing parabolic deflector 33 and into a trough 20 to which the outlet 10 is connected.  The aqueous juices which accumulate on the other side of the plate 19 remote from the channel 18 are removed via helical tubes 26 into a constriction 27 in the plate 151 and thence to a trough 29 from which depend the outlet 9.  The fibres and other residues which are separated against the wall of the bowl 4 are propelled towards the outlet 8 by the helical blades 6 and are dried, before reaching the outlet, by direct injection of steam or, as shown, indirectly by steam or warm water injected through the pipe 13 inside the bowl 5. Condensate from the interior of the bowl 5 may be passed through the conduits 17 to heat the cake as it is fed into the space between the bowls.
