Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations

1312292 Evaporators; film type MAXWELL DAVIDSON EVAPORATORS Ltd 19 April 1971 [4 March 1970] 10301/70 Addition to 1199154 Heading B1B In an evaporator stage wherein the liquid to be evaporated flows from reservoirs 17 through orifices 13 into passages 32 between pairs of vertical heat-transfer plates 10 and heating-fluid e.g. steam is supplied to the spaces between the pairs of plates, as disclosed in Specification 1199154, the liquid partially flashes into vapour as it passes through the orifices and the remaining liquid is evenly distributed from troughs 20 across the entire width of the plates 10 so that thin films of liquid flow down the plates. The main parts of plates 10 have diagonal corrugations; and the lower portions of the plates, which are bent up outwardly, also have corrugations which extend transversely to the main corrugations. Unevaporated liquid flows out of the lower ends of passages 32 into the channels 34 of tray 30, and then flows through spouts 39 into the reservoirs 17 of the next lower evaporator stage 52, (Fig. 5). The condensate of the heating fluid flows from passages 36 into the spaces between the channels 34 of tray 30, collects in troughs 40, and then flows to the heating passages of the subsequent stage. Some of the vapour evolved from the liquid in passages 32 passes through pipe 60 (Fig. 5) into heat-exchanger 58 where it is condensed, and the remainder of the vapour passes to the next stage. The concentrated liquid from the last stage S3 is mixed with fresh liquid to be evaporated, which is introduced through pipe 55, and the mixture is pupmed through heatexchangers 57, 58, 59 to the first stage S1. The final heat exchanger 59 is supplied with auxiliary steam. Process vapour withdrawn from the last stage is drawn into compressor 64, and the compressed vapour is introduced into the heating spaces of the first stage. The apparatus may be used for the desalination of sea water.

An evaporator comprises pairs of spaced plates, each pair defining an evaporating passage 112 which is heated indirectly by condensing fluid and which is closed at its entry and by a member 14 through which extends a feed pipe 13 for the liquid to be evaporated, the feed pipe terminating in a sparge pipe 12. Such an apparatus removes the danger of contamination of condensate of the heating fluid.

1,199,154. Plate heat exchangers. MAXWELL DAVIDSON EVAPORATORS Ltd. 13 Oct., 1967 [19 Oct., 1966], No. 46661/66. Heading F4S. [Also in Division B1] An evaporator stage in a distillation plant, e.g. a sea water desalination plant, comprises a plurality of pairs of vertically spaced parallel plates 10 arranged side-by-side in a casing 20. The plates of each pair are mirror images of one another and define therebetween a central evaporating passageway 32. Each plate 10 has a top portion 106 bent inwardly to form both a reservoir and a convergent-divergent passage for the liquid to be evaporated, and a bottom portion 1 is kinked at 14 and doubled back to form a channel 15. U-shaped partitions 18 are positioned as shown in these channels 15 to define heating passages 33 for the heating fluid namely steam. The condensate formed from the steam condensing accumulates in the channels 15 before eventually overflowing through recesses 10d in the plates 10 into outlet passages 36. Rubber diaphragms (21, Fig. 6, not shown) are provided to seal the plate and partition arrangement along opposite sides of the casing 20. Resilient diaphragms 22a, to which pressure may be applied, vary the spacing between parts 12 of the adjacent plates as required. Rods 17 floating in the reservoirs control the flow of liquid. Each plate 10 is provided with alternately inwardly and outwardly facing dimples 16. Several such evaporator stages may be arranged in series one above the other such that unevaporated liquid from one stage falls into the reservoirs of the stage below. The excess steam and condensate of one stage forms the heating fluid to be fed to the stage below.
