Title: Improvements in or relating to a device for discharging cohesive solids from an endless support
IPC: B01D33/00
Filed: 1944-11-28
Abstract: 576,967. Filters. OLIVER UNITED FILTERS, Inc. Nov. 28, 1944, No. 23717. Convention date, Dec. 11, 1943. [Class 46] A device for discharging a layer of wet cohesive solids, for example a filter cake, from an endless support comprises a discharge roll mounted across and adjacent to the support for rotation in the same clockwise direction as that of the support, whereby the roll causes the layer of solids to roll up continuously upon itself, and a discharge screw mounted at the rear of the discharge roll for rotation in the same clockwise direction as that of the roll, whereby part of the solids is withdrawn. In the construction shown, a rotary filter drum 7 divided into filtrate compartments each having communication with an automatic valve 8, is mounted within a tank 1 containing slurry to be filtered. A filter cake 9 is deposited on the drum by suction within the filter medium. The cake is wound up on itself to form a roll 33 by the action of a discharge roll 28 driven by means of a sprocket wheel 32 on a trunnion 6 which itself is driven by an electric motor. Part of the cake roll is removed bv a scroll 37 which is formed with a right-hand screw 38 and a left-band screw 39, so that as the scroll rotates the outer part of the cake roll is removed to both ends of the filter drum and discharged into slots 41, 42. Spray nozzles 46 for delivering water are provided to facilitate formation of the cake roll 33.

Abstract: 1,187,774. Hydrostatic transmissions. JOSEPH LUCAS (INDUSTRIES) Ltd. 18 July, 1967 [27 May, 1966], No. 23918/66. Heading F2D. [Also in Division F1] To provide a wide range of liquid flows in an hydrostatic transmission comprising two pumps 12, 13 connected in parallel in closed circuit with a motor 11, the pump 12, e.g., gear type, is of fixed output whereas the pump 13, e.g. variable-angle, over-centre, swash-plate type, is of variable output and reversible, the arrangement being such that the pump 13 is variable from one extreme position in which it discharges at maximum capacity in the same direction as the pump 12 for maximum pumping output to the motor, through an intermediate zero discharge position for pumping output to the motor from the pump 12 only, to the opposite extreme position in which it discharges at maximum capacity in the opposite direction to the pump 12, i.e. it feeds the latter, for minimum pumping output to the motor. Where the pumps are of equal output in opposite directions, minimum pumping output to the motor is zero. The pumps 12, 13 are driven by a prime mover 10 through shafts 14, 15. Liquid losses are replenished from a reservoir 17 through a filter 18. A restriction 16 provides a back pressure for the pump 13, when the latter discharges in the pump 12 direction, so as to provide the positive inlet pressure desirable for swash-plate pumps.

[Also in Group XL (c)] A two-terminal circuit exhibiting a negative impedance comprises two transformers each having one winding connected, either in series or in parallel with the corresponding winding of the other, between the terminals of the circuit, the other windings being connected to the input and the output of a valve amplifier respectively and the two transformers being so connected with respect to each other that a negative impedance appears across the terminals of the circuit. Fig. 1 shows the circuit in its simplest form with one winding of each of transformers 3, and 6 connected in series between the terminals 1 and 2 which are inserted in series in a telephone line 25, 26. Fig. 4 shows a practical embodiment; an equalizing circuit chosen to give a desired value of negative impedance is connected between points 8, 9 and 10. Fig. 5 shows an alternative form of circuit which is preferably inserted in parallel with the telephone line 25, 26. In this circuit the primary winding of transformer 3<1> is arranged in parallel with the secondary winding of transformer 6<1> across the line 25, 26. Resistors 12 and 13 having a high value are provided to limit the current flowing through the transformer 3<1> and render it independent of the impedance presented by the transformer. The amplifier 4<1> may employ negative feedback provided by resistors in the cathode circuit of the amplifying valve, Figs. 7 and 8 (not shown). The two forms of circuit illustrated may be combined as indicated in Fig. 11 in which the two negative impedances have the reference numerals 23 and 24. In this arrangement the transformers 3 and 6 in the series circuit are preferably modified so that the parallel circuit can be inserted into the circuit symmetrically with respect to the series circuit, Fig. 12 (not shown).

Another portion of the mix was calendered on to a supporting layer of fabric and cured in hot air at 125 DEG C. for 25-30 minutes.  The blowing agent is preferably di-N-nitrosopentamethylene tetramine although sodium bicarbonate, ammo nium bicarbonate, diazoaminobenzene or di-N-sulphonhydrazide may be used.

Abstract: 857,209. Controllers. PILLIN Ltd., J. B., and EARLY, K. C. April 23, 1959 [July 30, 1958], No. 24587/58. Class 38 (3). When a hand lever 17 opens a petrol-delivery valve, the pressure in pipe 15 falls and a pressure-responsive switch 21 is closed to energize coil 24. This operates a time-delay escapement mechanism 26 and closes a contact 27, whereby a starter 13 energizes motor 11 for driving pump 10. The contact 27 is kept closed, despite intermittent actuation of the switch 21 due to variations in the fluid-pressure, until the hand-operated valve is closed and a steady pressure is built up in the delivery pipe so that the switch 21 is opened continuously for a predetermined period. In this manner, the motor and starter are not subjected to rapidly fluctuating current which may cause over-heating. When the delivery nozzle 16 is not in use it is placed ina socket and a cam-operated switch 28 is opened to stop the motor.

Abstract: 260,236. I. G. Farbenindustrie Akt.- Ges., (Assignees of Chemische Fabrik Griesheim-Elektron). Oct. 24, 1925, [Convention date]. Carbon bisulphide, distilling.-In saparating crude carbon bisulphide into pure carbon bisulphide, sulphuretted hydrogen and sulphur, the crude liquid is fed into the upper part of a column A from which the residual liquid passes into a still A<2>. Carbon bisulphide vapours pass from the base of the column through a pipe x to the top of a column B. Residual liquid containing sulphur passes into a still B<2>, which may be arranged as an annular chamber above the still A<2>. Pure carbon bisulphide vapours pass from the base of the column to a condenser C. Sulphuretted hydrogen passes from the upper parts of the columns through reflux condensers A', B<1>, and through a final condenser D, the condensate from which is passed into the column A. The still A<2> is maintained at a temperature above the melting-point of sulphur, and the still B<2> slightly above the boiling-point of carbon bisulphide. Residue from the still B<2> is passed into the still A<2>, and liquid sulphur is discharged from the still A<2>. The columns are surrounded by heatinsulating material.
