Title: Improvements in the regulation of multiple-effect evaporators
IPC: B01D1/00
Filed: 1965-10-12
Abstract: 1,129,171. Multiple-effect evaporators. SOC. FIVES LILLE-CAIL. 12 Oct., 1965 [13 Oct., 1964; 6 Jan., 1965], No. 43215/65. Heading BIB. In an installation comprising a multipleeffect evaporator 1<SP>1</SP> . .. 4<SP>1</SP> associated with an auxiliary evaporator 6<SP>1</SP> and an evaporatorcrystalliser 5<SP>1</SP> which is heated by a portion of the vapours taken from one of the effects (e.g. effect 2<SP>1</SP> as shown), auxiliary evaporator 6<SP>1</SP> is supplied with vapour from crystalliser 5<SP>1</SP> and, if required, with vapour obtained by autoevaporation in vessel 25 of the condensate withdrawn from the heating-chambers of evaporators 1<SP>1</SP> . . . 4<SP>1</SP> into heat-storer 35, and the concentration of the solution withdrawn from evaporator 6<SP>1</SP> is regulated by a regulator 13<SP>1</SP> which controls the valves admitting the vapour to evaporator 6<SP>1</SP>. For example, a drop in concentration of the solution detected by regulator 13<SP>1</SP> results in the opening of valve 14<SP>1</SP>. If the corresponding increase in the flow of vapour coming from crystalliser 5<SP>1</SP> into evaporator 6<SP>1</SP> is inadequate to compensate for the drop in concentration, regulator 13<SP>1</SP> acts on valve 28 and thus permits some of the condensate contained in heat storer 35 to flow to, and evaporate in, vessel 25. The opening of valves 14<SP>1</SP> and 28 brings about an increase in the evaporation in evaporator 6<SP>1</SP>. When the concentration of the solution attains the desired set value, regulator 13<SP>1</SP> acts first on valve 28 so as to close it, and subsequently on valve 14<SP>1</SP> so as to reduce the inflow of vapour from crystalliser 5<SP>1</SP> into evaporator 6<SP>1</SP>. Regulator 8<SP>1</SP> controls valve 10<SP>1</SP> which admits live steam into evaporator 1<SP>1</SP> in accordance with the flow to this effect of the solution to be concentrated, which is regulated by valve 17<SP>1</SP>. Vapours may be discharged from effects 1<SP>1</SP>, 21 and 3<SP>1</SP> at 20<SP>1</SP>, 21<SP>1</SP> and 22<SP>1</SP>; but the flow of vapour from effect 41 should be nil. In an alternative embodiment, the solution may be fed in parallel to evaporators 1<SP>1</SP> and 6<SP>1</SP>, in which case the solutions discharged from evaporators 4<SP>1</SP> and 6<SP>1</SP> are mixed, and the concentration of the mixture regulates the supply of vapour from the crystalliser to evaporator 6<SP>1</SP>.

Means 21-27 constitutes a perforated disc 23, on a shaft, 22, driven from shaft, 6, through gears 21, which disc transmits light pulses from a source 24 to a photo-cell 25 and an amplifier, thus a pulse train with p.r.f.v proportional to shaft speed is produced. A network 27 generates the voltage U 1  from the pulse train which is also applied to the input of a counter 28 to produce an output signal after a given number of pulses such that a residual length S o  remains of a required length to be cut. Thus the length S x  decreases from an initial value of S o  to a final value of zero and braking is controlled so that the pawl 13 and the ratchet wheel 14, which lock the paper at a required cutting position, are brought gently into engagement. The brake 19 acts on a disc 17 carried on a shaft 16 geared at 18 to the shaft 6 which is driven from a motor 3 through gears 4 and friction clutch 5. The movement of the pawl 13 is controlled by an electromagnet 12.

Abstract: 1,099,170. Power-assisted steering mechanism. ZAHNRADFABRIK FRIEDRICHSHAFEN A.G. Oct. 6, 1966 [Oct. 7, 1965], No. 44708/66. Heading B7H. In power-assisted steering mechanism comprising a control valve 15, a servo pump 5, and a positive displacement pump 4 actuated by the steering shaft 1, a non-return valve 42 is disposed in the supply line 18 between the servo pump 5 and the valve 15. Movement of the steering shaft 1 as a result of road shocks causing pressure surges which open a pressure relief valve 41 is thereby prevented. The pump (Fig. 8, not shown) which is driven through an Oldham couplings or, as shown, is keyed to coupling member 3 driven from the shaft 1 through means permitting a limited degree of relative rotation. The valve 15 rotates with the coupling member 3 and is connected to the steering shaft 1 through a screwed coupling 17 which produces axial displacement of the valve 15 in response to relative rotation between the shaft 1 and member 3. When the valve 15 occupies a neutral position, fluid delivered by the servo pump 5 to a groove 19 returns through a passage 33, groove 34 and pipe 31 to a reservoir 32. Upon displacement of the valve 15, fluid from the groove 19 flows through slots 13 or 14, radial bores 38 or 39 and respective ones of axial bores 12 to the pump 4. Fluid leaving the pump 4 flows through the remaining bores 12, radial bores 38, 39 and slots 13, 14 to one of grooves 22, 27 communicating with the respective ends 24, 25 of a servo cylinder. The other groove 22, 27 is placed in communication with the reservoir through the interior of the valve 15. A valve 35 permits manual operation of the steering mechanism should the pressure supply from the servo pump 5 fail. Another embodiment (Fig. 5, not shown) employs a control valve displaced against spring loading by the pressure differential across the positive displacement pump.
