Filed: 1972-03-07
Abstract: 1343749 Rolling mill plant SOC DETUDES TECHNIQUES DES INDUSTRIES METALLURGIQUES 7 March 1972 [5 April 1971] 10613/72 Heading B3M [Also in Division B8] Apparatus for turning elongated rolled articles 1 supported on a roller conveyer or a fixed support 2 comprises two sets of arms 3, 5, each set being secured to a respective rotatable shaft 4, 6. The arms 3 have a rectilinear support surface 3a and a surface 3b at right-angles thereto, whilst the arms 5 have a pair of surfaces 5c, 5d disposed at an obtuse angle to each other. The angle lying between 90 and 135 degrees. In operation the arms 3 are rotated to lift the article, the arms 5 are then rotated so that the surface 5c engages the article and lifts same from the arms 3. The arms 3 are then returned to their initial position, Fig. 4 (not shown), the arms 5 then being lowered causing the article to turn over such that its face lc abuts the surface 5d. The article is then deposited on the face 1c on the convyer or fixed support. In an alternative mode of operation the arms (5) are raised first to engage the article with surface (5d). On further raising of the arms (5) the article pivots about its edge so that its surface (1d) abuts the surface (5c). The arms (3) are then raised to lift the article from the arms (5), the arms 5 lowered and finally the arms 3 are lowered to deposit the turned article on the conveyer or support surface.

Title: Treatment of sea water for evaporating plants
IPC: C02F5/08
Filed: 1951-05-07
Abstract: <PICT:0734755/III/1> To prevent the formation of scale, ferric or zinc or aluminium chloride or sulphate is introduced into the evaporating shell or shells of a sea water evaporating plant or into the feed water for the plant.  0.25 pounds of salt per ton of sea water is added. The addition causes precipitation of magnesium as magnesium hydroxide and carbonate is destroyed by the acidity resulting from the hydrolysis of the added salts.  Three apparatus are described.  In Fig. 1 sea water is fed by pump 5 through an ejector condenser 6, a main condenser 7 and line 8 to evaporator 3. Part is by-passed to waste at 16 and part is fed to tank 18 to which a salt or solution of a salt-e.g. ferric chloride-is added from a funnel 19.  From the tank the feed passes to evaporator 3. The evaporator operates under vacuum created by ejector 13 in condenser 7.  Condensate from condenser 7 is pumped to distilled water tank 12 which also receives condensate from heating-coil 2 and condenser 6. Brine is withdrawn at 22.  The apparatus of Fig. 2 (not shown), is similar but solution from tank 18 is pumped to the evaporator 3 instead of flowing by gravity.  The apparatus of Fig. 3 (not shown) is similar to that of Fig. 2 but is a multiple effect apparatus, the feed water being fed from a tank in which it is mixed with the salt in parallel or in series to the separate effects through heat exchangers heated by the vapours from the separate effects.  The brine is withdrawn in series or parallel.ALSO:To prevent scale formation in sea-water evaporators 0.25 pounds of ferric or aluminium or zinc chloride or sulphate per ton of sea-water is added to the feed to the evaporator or injected into the evaporator (see Group III).

[Class 4] [Also in Group XXII] In a method of determining or checking the position of jigs in an erecting device for the production or assembly of work-pieces such as aircraft parts, a pattern corresponding to the work-piece is used for setting the jigs in the erecting device. A pattern 7 is used for positioning the jigs 2 ... 6 in a portable erecting device 1, the jigs being adjustably secured by clamps 8 ... 10. To facilitate the setting of the jigs, a wire 16 may form a reference line for the pattern, and plumb lines 17 ... 19 and a second wire 30 may define a vertical plane. The connections 21 ... 27 on the jigs are aligned with the corresponding parts of the pattern and the clamps 8 ... 10 then secured. Instead of using wires, the pattern may be positioned optically with the aid of a sighting tube on the erecting device and cross wires carried by angle brackets at three fixed points on the pattern. The erecting device 1 may be positioned with its feet 11, 12 in a horizontal plane by means of supporting blocks 14, 15.

[Class 39 (i)] In an electrostatic precipitator, a collector cell comprises a, plurality of spaced, parallel, alternately grounded and insulated collector plates supported between parallel end plates, the grounded plates by rods extending transversely through them and secured to the end plates, and the insulated plates by rods extending perpendicular to them and secured to insulators mounted on the end plates. The grounded plates 14 are mounted on rods 13 and spaced apart by metallic spacers 15. The insulated plates 22 are similarly mounted and spaced, but two of the rods 27 are threaded in bushings held in disc-shaped ceramic insulators 29. The insulators 29 have cylindrical portions held in inwardly extending portions of a bracket 17 by cotter pins. With the cotter pins removed the insulators can be rotated to move the rods axially and so adjust the spacing between the grounded and insulated plates. The brackets 17 are secured to the end plates 10 upon which the rods 13 for the grounded plates are mounted. The brackets 17 together with flanges on the end plates 10 completely enclose the insulators 29. Several similar cells may be stacked together in abutting relation in a precipitator.

Title: Improvements in and relating to evaporators
IPC: B01D3/06
Filed: 1956-04-11
Abstract: <PICT:0823239/III/1> <PICT:0823239/III/2> In an evaporator comprising a heater, a number of flash chambers connected in series, and a circulating pump the input side of which is connected to the liquid-discharge of the series of flash chambers so that at least part of the discharged liquid is recirculated through the flash chambers, control means are provided for automatically reducing the quantity of liquid recirculated through the flash chambers by the pump when the liquid in one of flash chambers at higher pressure reaches a predetermined level.  The apparatus shown (Fig. 1) comprises a number of series-connected heaters in a vessel 10 which is joined via line 14 to the vessel 12 which houses the flash chambers.  The vapours from the flash chambers are passed into the heaters via pipes (not shown).  Part of the concentrated liquid withdrawn from the last flash chamber is discharged via line 18, and the remainder is recirculated by pump 22 to the heaters via pipe 26. Fresh make-up liquid is supplied through line 24.  The flash chambers 28 (Fig. 2), are formed by partitions 30 and connected in series by orifices 32.  The hot liquid from the heaters 10 enters chamber H through orifice 34, and leaves chamber L through pipe 36.  Orifices 32 and 34 are dimensioned so as to suit full load operation. Carry-over of liquid from chamber H, and from the immediately adjacent chambers, in the vapours passing to the heaters 10, is obviated by throttle valve 38 which controls the effective output of pump 22, the valve being itself regulated through link 40 by the liquid-lever sensitive device 42 arranged in chamber H.  Link 40 may be operated by electrical, mechanical, hydraulic, or pneumatic means. Thus, when the liquid-lever 44 in chamber H reaches such a height as to actuate device 42, the valve is automatically moved so as to reduce the output of pump 22, which brings down the liquid-level in chamber H to a safe value. In an alternative arrangement, a by-pass, provided with a throttle valve, is connected to the delivery side of the pump so as to lead liquid directly back to the suction side.  A valve may also be inserted in line 24 to limit the admission of make-up liquid to the evaporator in accordance with the liquid-level in chamber L.
