Title: Improvements in and relating to Multiple-Effect Falling-Film Evaporators
IPC: F28D7/16
Filed: 1967-04-24
Abstract: 1,178,031. Evaporators, multiple-effect type; desalination of water. STEARNS-ROGER CORP. 24 April, 1967 [29 April, 1966], No. 18708/67. Heading B1B. Liquid, e.g. sea water, is evaporated by passing it successively through a plurality of banks of falling-film evaporator tubes 50 disposed in a thermally-insulated unitary enclosure 12 divided by vertical partitions 58, 60 into a series of chambers, each maintained at a lower pressure than the preceding chamber, the arrangement being such that the vapour given off in each bank of tubes 50 acts as heating- medium for the succeeding bank of tubes. The first bank of tubes is heated by steam from a boiler. Each partition 58 extends from the bottom of the enclosure 12 up to plate 64; and each partition 60 depends from the top and terminates just above the bottom of the en closure. Each chamber contains a bank of evaporator tubes 50 and a U-tube heatexchanger 48. The openings 90, 92 in plate 64 allow the hot vapour to circulate over the tubes. The lower ends of the tubes are surrounded by a tank 56 for the condensate which flows through a pipe 80 into tank 36 which is connected to a similar tank in the next effect, where partial flashing occurs. The process vapours pass from the reservoir 18 over the top of partition 58 into the following effect. Feed liquid enters the heat-exchanger 48 through inlet 110; and the preheated feed flows through an outlet to the heat-exchanger of the preceding effect, and finally to the annular distributor 52 in the dome 54 of the first effect. Concentrated liquor is withdrawn from reservoir 18 through outlet 20 and is pumped to the dome of the next effect. In the case of the last effect, the concentrated liquor is either withdrawn from the system, or recirculated to the evaporator tubes of the last effect. Non-condensable gases are withdrawn from tank 56 through line 142. The steamcondensate withdrawn from the first effect may be used to preheat the feed liquid, before being introduced into the flash tank 36 of the second effect. Before entering the heat-exchanger 48 of the last effect, the feed liquid may be preheated by heat-exchange with the vapour withdrawn from the last effect, and with the condensate withdrawn from the flash tank 36 of the final effect. The cooled condensate is the purified product, e.g. desalinated water.

Abstract: 842,684. Sifting apparatus. JONSSON, A. S. June 18, 1958 [June 20, 1957], No. 19498/58. Class 117 [Also in Group XIII] Apparatus for cleaning granular material e.g. grain, comprises an aspirator 10, Fig. 1, having an annular air passage wherein the grain is separated from lighter matter by air which enters the lower portion of the aspirator from a vibratory sieve 14 secured thereto, which sieve has inclined sieve-plates 26 for cleaning the grain which is delivered from the aspirator and which has currents of air, which may be preheated, entering through apertures 58, 62 for drying the grain thereon. The sieves, which are oscillated by a vibrator 48 and which have collecting pipes 45, 47, 49 at their lower ends, are arranged one above the other on a frame which is supported by springs 32 and pivoted at 36 to vary the inclination of the sieves. The vibrator 48 also oscillates a sieve 16 within the aspirator by means of a rod 56 which is connected from the sieve 14 to a frame 54 on which the aspirator rests. A fan 66 withdraws air from the aspirator through a duct 64 and leads it to cyclone separators 70 from which it is returned to the apparatus by a conduit 72 and apertures 62. Air may be led from the conduit through pipes 76 and be cleaned in a wet dust separator 82 before discharge to the atmosphere. In a modification. the vibratory sieve has apertures 133, Fig. 2, in the side walls between sieves 104, 106, 108, 110, 112 arranged in series with each other and alternately slanting in opposite directions and imperforate bottoms 114, 116, 118, 120 beneath each sieve. The sieves and bottoms are secured to end walls 122, 124 by means of hooks 136 and the lower ends of the bottoms have collecting shoots 138 for sieved materials. Deflecting members comprising vanes 140 pivotally mounted at 142 parallel to the discharge ends of the sieves and having separating edges, are directed towards and into the approaching grain layer to deflect the uppermost layer to be the lowermost layer on the next following sieve. In a further modification the inlet to the aspirator comprises telescopic tubes 18a, 18b, Fig. 3, by which the outlet mouth may be set to various distances above the surface 17 of a distributing cone 16<SP>1</SP> to improve uniform dispersion of the grain. A vibrator 21 actuates the cone and annular slots 25, 27 formed in the cone and between the lower edge of the cone and surrounding outer shell 10 respectively allow air to flow upwardly to entrain light impurities.
Patent GB-498835-A (GB)
Title: Improvements in or relating to electromagnetic light-current relays
IPC: H01H51/10
Filed: 1937-07-14
Abstract: 498,835. Light current relays. STANDARD TELEPHONES & CABLES, Ltd., and TERRY, R. ST. G. Ju]y 14, 1937, No. 19541. [Class 38 (v)] In a relay which is operated by one coil and latched and later released by energisation of a second coil, the operating and release armatures of the two coils are pivoted on the same axis and have extensions which co-operate with a pivoted latching pawl, the plane of which is perpendicular to the extensions. As shown in Fig. 3, the operating and releasing coils are mounted sideby-side around and are adapted to attract coaxially pivoted armatures 3, 23. The armature 3 carries a latching member comprising a plate 5 formed with a latching extension 27 and the armature 23 carries a latching member 26 having an upright arm 25 from which is offset a lateral latching extension 28. The latching pawl 12, Fig. 4, is pivoted at the top of a pillar 10 and a spiral spring on the stud engages with the arm 30 of the pawl and normally urges the latching arm 29 against the side of the latching projection 27. When the operating armature 3 is attracted by energization of the operating electromagnet 2, the plate 5 is moved away from the pawl 12 so that the latching extension 29 of the pawl is pulled behind the extension 27 so holding the armature 3 in the operated position even though the energizing circuit of the coil 3 is broken by contact springs operated by the armature. The armature 3 is subsequently released by attraction of the releasing armature 23 to the releasing coil 22, the arm 28 of the latching extension engaging the arm 30 of the pawl to rock the latter against its spring so that the pawl 29 is moved from behind the latching extension 27 so releasing the armature. The plate 5 with its extension 27 consists of a main plate backed by a spring plate and the point at which latching takes place may be adjusted by adjustment of the spring plate relatively to the plate 5 by means of a screw 8 passing through the latter and bearing on the spring plate. The coil 2 may be provided with a slug and /or a non-inductive shunt connected in parallel with the winding so that break contacts for the winding circuit may be operated before the armature has completed its stroke in which case the energy stored in the slug and/or shunt winding is sufficient to cause the armature to complete its stroke and allow the latching operation to be completed.
