Title: Improvements in or relating to the clarification of starch conversion liquors
Inventor: FROST GEORGE BAXTER
IPC: C13K1/08
Filed: 1951-04-06
Abstract: Starch conversion liquors having a pH value less than 7 and contaminated by a substance which can be removed by causing it to flocculate are clarified by increasing the pH value of the liquor whilst maintaining it at at least 80 DEG C by the addition of an alkaline substance, viz. one or more of the following, carbonates, sesquicarbonates, bicarbonates and hydroxides of the alkali metals and alkaline phosphates, silicates and aluminates, to a value at which flocculation occurs, adding finely divided bentonite and then removing the flocculating or precipitating matter from the liquor The fine colloidal materials are added in the form of hydro-sols or hydro-gels but the coarser materials may be added direct to the liquor.  Bleaching agents more particularly alkaline and alkaline earth salts of chlorous acid, hypochlorous acid and sulphurous acid may be added initially if the liquor contains non-colloidal soluble colouring matter.  After removal of the flocculating material the liquor may be treated with activated carbon.
Patent GB-1047071-A (GB)
Title: Process for the preparation of epsilon-caprolactam
IPC: C07D201/08
Filed: 1964-02-26
Abstract: e -Caprolactam is prepared by heating at least one of the compounds e - caprolactone, e -hydroxycaproamide and amide forming derivatives of e -hydroxycaproic acid, in aqueous ammonia, in an atmosphere comprising free hydrogen to a temperature within the range 200-420 DEG  C., under a pressure at least sufficient to maintain a liquid phase in the reaction zone. Suitable derivatives of e -hydroxycaproic acid are its alkyl, cycloalkyl, aralkyl and aryl esters, or its ammonium and alkali metal salts.  The reaction may be carried out in an atmosphere of hydrogen alone, or hydrogen mixed with other inert gases, e.g. nitrogen and helium.  In this case the partial pressure of hydrogen is advantageously 0.01-100 atms.  The preferred concentration of ammonia is 0.1-35% by weight, and the preferred mol. ratio of caproic acid derivative starting material to aqueous ammonia (in terms of pure ammonia) ranges from 1:1 to 1:25.  The lactam is isolated from the aqueous ammonia solution of lactam produced and after the extraction the residue may be recycled.

Abstract: 589,896. Wringers. CO-OPERATIVE WHOLESALE SOCIETY, Ltd., and MOORE, J. R. March 30, 1945, No. 8091. [Class 138 (ii)] The drip tray of a wringer is in the form of a single fitting having upper and lower walls 2, 1 projecting from either side of the rollers. The fitting is rockable between two positions in which either upper wall 2 is inclined or horizontal, so that the machine can be used from either side; when inclined the upper wall keeps articles fed to the rollers clear of drain water passing away to a drain hole 4 at the outer edge of the lower wall, whilst when horizontal it lies adjacent the lower roller just below the nip and serves. as a mangling board. In Fig. 1 the fitting is formed from a metal strip, folded over at its two ends to form the upper walls, and secured to end plates 5. The latter have inverted T-slots 10 by which they are engaged over the journals of the lower roller, and which limit the rocking movement about pivots 7. The upper walls 2 may, alternatively, be removable to facilitate cleaning the interior of the fitting. In Fig. 2 the upper walls are formed as separate parts 15, 16 secured to a lower tray part 14. The upper parts have inturned lugs 20 to engage the lower roller or its journal, or, as shown, ribs 21 formed on the side frames. This constitutes the pivotal mounting of the fitting, movement being limited by T-slots 23 in the side frames in which pins 22 on the fitting work. Specification 523,273 is referred to.

Solids may be separated out in the cyclone, fall into the container 4 and be removed therefrom as by a screw apparatus 5 or by other means, and liquid may be supplied to the container in counterflow to the solids being removed by the screw. The apparatus may be used to form a concentration of liquid containing solid particles, the concentration being removed from the container 4. The latter may be constructed as a classifier by fitting to its bottom a downcomer, for the solid particles, in which an up-current of liquid flows. The diffuser cover plate 14 may have a flat bottom. The apparatus may be used for the separation of shale from raw coal or separation of gangue from ores.

Tip-wagons; hopper wagons. -The dumping wagon described in the parent Specification is modified in that, for effecting the tipping and return movements of the body A by means of the compressed air gear, the curved member which cooperates with an actuating member on the piston-rod is replaced by a two-armed lever D, Fig. 1, one arm d<1> of which coacts with a lug c<3> on the piston-rod c<1> during the tipping movement, while the other arm d<2> coacts with the lug during the return movement. The piston rod c<1> has at its upper end a slot c<2> engaged with lost motion by a detachable pin a<4> on the body. During the first part of the movement of the rod c<1> the pin a<4> passes from the upper to the lower part of the slot c<2>, while the lug c<3> displaces the arm d<1> of the lever D, which is keyed to the rotary operating-shaft a<2>, and so unlocks the toggle b<2>, a<1> against the influence of a tension spring K. At the end of the discharging movement, Fig. 4, the arm d<2> engages the lug c<3> to prevent overthrow of the toggle, and also to be in readiness for rotating the shaft a<2> in the reverse direction during the return movement of the body. When the discharge is to be effected by the hand gear, the pin a<4> is removed so as entirely to disconnect the compressed air gear, and the tipping is carried out as in the parent Specification by means of a loose sleeve E, which is operated by a handlever F and carries a double pawl G co-operating with a ratchet wheel H on the shaft a<2>.
