Patent GB-867811-A (GB)
Title: Apparatus sensitive to the water content of vapour above chemical cleaning liquids
Inventor: HESS RICHARD
IPC: G01N25/56
Filed: 1958-08-19
Abstract: 867,811. Humidity measurement. STOCKHAUSEN, J. Aug. 19, 1958, No. 26649/58. Class 40 (1). [Also in Groups XX, XXIII and XXXV] The water content of drycleaning fluid is measured by arranging a hygrometer in the vapour above the fluid in a chamber separate from the cleaning installation, the fluid entering and leaving by liquid seals. Preferably the hygrometer sensing member nearly fills the vapour space and the entering fluid runs down the walls of the space without coming into contact with the hygrometer, being kept away by a gaspermeable network or bars, e.g. the fluid can trickle over packing material in the chamber. The latter may comprise a double cylinder with the fluid between the walls. For accurate results the fluid should be brought to a constant temperature by passing it through a heatexchanger before it enters the chamber. The temperature may be 15-30‹ C. depending on the volatility of the solvent used. In Fig. I the fluid enters at 3 into a surrounding jacket and passes via 5 to form a constant head between the edges 7 and 11 before flowing down past the hygrometer element 9. The latter comprises a flat plate of insulating material containing a gold grid covered with a layer of lithium chloride whose conductivity varies with moisture content. The fluid then emerges via the liquid seal 6. The variation of resistance of the element produces electrical signals which can control the addition of water to the main body of fluid (see Group XXXV). The hygrometer can also be a non-electric type (see Group XX).

Abstract: 1525036 Electromagnetic stirring INSTITUT DE RECHERCHES DE LA SIDERURGIE FRANCAISE 28 June 1976 [27 June 1975] 26765/76 Heading B1C [Also in Division B3] To reduce inclusions in the surface of a continuous casting, the molten metal in a non-magnetic mould 14 (of Cu or Cr alloy and possibly inclined or curved) is rotated by an electromagnetic inductor 38 (with yoke 50) with saliant poles 47, 47" arranged around a non-magnetic (stainless steel) jacket 22 spaced (by studs 30, 30') from the mould 14 so that coolant (water) can flow from a (small) lower chamber 23, above a bottom plate 6, through the space 21 around the mould to a (larger) outlet chamber 24 beneath a cover 5 and containing the inductor 38 and separated from the chamber 23 by a fluid-tight partition comprising an annular plate assembly 31, (36, 37, 64) secured on the jacket 22 and a co-operating ring assembly 32, 33 secured in a casing 2 of the water chambers; the inductor 38 is supported by a collar 40 on the jacket 22 and the jacket, in turn, is supported by the plate 31 (resting, by way of a rubber gasket 64, on an edge 35 of the ring assembly 32, 33) while the mould 14 is located by a flange 15 at its top (resting, in a recess 16 in the cover 5) and by its bottom engaging an O-ring 18 in the bottom plate 6. There are double windings 48, 49 about the poles 47, 47" while ribs 54 (Fig. 4 also) are fixed along the jacket 22 between the poles to prevent rotation of the inductor. The mould may be mounted on a vibratory table. Mould lubricant is injected through radial ducts 45 in the cover 5 to pass to the mould mouth 10 by way of a space 51 below a plate 52. A top plate 42 hinged at C closes down on the plate 52 and is secured by a cotter 59. For producing smaller-sectioned and different-shaped castings, the mould 14 and jacket 22 with their attachments, are removed and there are substituted narrower replacements (Fig. 4 shows half sections of two possible forms). To bridge the gaps between the poles 47 and the jacket 22, longitudinal magnetic members 69, e.g. welded, screwed, riveted or stuck to the jacket 22, are interposed. There may be a small gap between each member 69 and its pole 47. or a tongue- and-groove connection of arrowhead section if the members 69 are not secured to the jacket. To provide the necessary smaller holes at the top and bottom of the mould assembly, stepped rings are fitted in the apertures of the cover 5 and bottom plate 6.

The blade may have parallel or tapered inclined edges and it may have normal apertures 20 or transverse slots, straight or arcuate and the adjustment may be such that one edge of the blade projects beyond the comb teeth to permit stropping. The clamping plates may be flat or transversely curved and the protecting comb plate 17 may be wider than or the same width as the comb 15. One side of the comb teeth of the protecting comb may be omitted as shown in Fig. 6 and the comb 15 at this side extended and formed with teeth 22 for normal hair combing.

A fan 4 transfers the stored heat to the circulating liquid when called to do so by a room temperature thermostat RS. If the air temperature falls below 150 F. a thermostat 14 closes to energize a relay 9, 10 thereby enabling a boiler in the form of a resistance heater to directly heat the circulating liquid. A further reduction of the air temperature below 120 F. causes a thermostat 18 to close so that a relay 16, 17 is energized to enable an additional boiler in the form of a resistance heater to directly heat the circulating liquid. During the night period, the relay 19, 20 is energized to prevent operation of the fan 4 and to prevent energization of the relay 16, 17 by opening the contacts 19. Only the boiler connected to the relay 9, 10 is therefore operative during the night period and the current supply to the storage mass 1, 2, 3 is cut off by a regulator 8 when the storage mass attains a predetermined temperature.
