Patent GB-788398-A (GB)
Title: Feed-control system in distillation apparatus
IPC: B01D1/00
Filed: 1954-11-05
Abstract: In distillation apparatus comprising a distilland-supply tank A, a still B, and a condenser K, the condensate, receiver C floats freely in the distilland in tank A; and during the distillation, the receiver gradually descends in tank A and displaces distilland from the tank through pipe E into still B whereby a constant liquid-level is maintained therein.  A tube AX extends down from the centre of the base of tank A, and terminates in a drain-cock T7.  The base of the receiver C is also provided with an extension tube CX.  The pipe X which delivers condensate to the receiver C passes through the lid of tank A and a collar at the top of receiver C and then extends down through receiver C and into tube CX to a level about 1/2 inch below that of the base of the tank A.  When the apparatus is to be put in operation, distilland is pumped through pipe PD into the tank until the liquid in the tank and the still reaches level O.  The lower end of tube CX then penetrates into tube AX to a depth of <PICT:0788398/III/1> 1 inch.  The arrangement is such that the receiver C can rotate freely about tube X.  The still B is supported in a hot water bath.  The base of the still has a vertical cylindrical section B1 to which is attached a tube B2 which passes through the side-wall of the still and is open to the atmosphere. The vapours evolved in the still pass up fractionating column F and into condenser K. At the completion of the distillation, the receiver C will have received its designed volume of distillate and will have descended to rest on the base of tank A.  To remove the distillate to store, compressed air is applied to nozzle P and forces the distillate up pipe X and out through pipe S.

Abstract: 448,761. Road - repairing machines. RANDS, F. C., and ALEXANDER, T. F. N., Windsor House, Kingsway, London. Nov. 21, 1935, No. 32310. [Class 107] Relates to apparatus for liquefying or softening the surface binder of a road by heat and then skimming off part of the surfacing material from the high places. According to the invention, the apparatus consists of a wheeled chassis 1, carrying a rigid scraperrake 12 and a brush 13 mounted behind the rake. The rake is adapted to follow a roadsurface heating device which may, as shown, be carried by the chassis 1. The machine may also carry a hopper 15 for distributing fresh road-surfacing material such as slag, gravel, limestone, or granite, upon the road, and a further scraper-rake 14 is provided for spreading this material. The scraper-rakes 12, 14, are similar in construction and are slidably mounted in guides 17 and provided, like the brush 13, with adjusting screws 16.

Title: Improvements in and relating to a process for the manufacture of thrombin
IPC: C12N9/74
Filed: 1937-11-25
Abstract: Thrombin is prepared from a solution in water of a precipitate obtained by adding a water-miscible organic solvent to a fibrin solution, wherein the water extraction of the crude precipitate is effected in presence of an alkaline substance to increase the pH of the extract, and the thrombin is precipitated from this solution by addition of a water-miscible organic solvent such as acetone.  The alkaline substance may be added in such quantity as to make the pH=6,5-7,5.  The initial crude solution may be obtained by extracting fresh dried fibrin, and this drying may be effected by the acid of an organic solvent.  In an example, (1) fresh fibrin is washed, pressed, minced, and extracted with salt solution; acetone is added to precipitate crude thrombin, and the precipitate is treated with water and caustic soda at pH 7,2; the undissolved matter is removed centrifugally and the thrombin is precipitated by acetone and washed with acetone and then with ether; (2) thrombin is prepared from fibrin dried with acetone and ether, the extraction of the crude thrombin precipitated being effected at pH 7,47.

Title: Hydrolysis process
IPC: C13K1/06
Filed: 1946-11-05
Abstract: A number of hydrolysable materials having different rates of hydrolysis reaction are hydrolysed in a continuous reaction by hydrolysing first the more difficultly-hydrolysable material and then adding the more readily hydrolysable material before the reaction is complete.  The process is particularly applicable to the production of mixed sugar syrups from the hydrolysis products of starch and sucrose or insulin.  In an example, starch is heated in the ordinary way with acid, preferably hydrochloric acid, until the dextrose equivalent of the mixture is 35-57 per cent. The mixture is then discharged into the neutralizer to which is added, either previously or simultaneously, sucrose in solution or crystallized form, the addition of the neutralizing substance being delayed until hydrolysis of the sucrose is completed.ALSO:In order to produce an extra sweet syrup, starch is hydrolyzed by the action of acid and heat and, while the reaction is still proceeding, sucrose or inulin is added so that a mixed sugar syrup is obtained.

[Class 78 (iv)] In jib cranes of the kind in which the load moves in a horizontal plane during luffing, two points of the jib are guided along fixed guides during luffing, the upper guide being designed relatively to the lower guide so that the suspension pulley 13 of the load carried by the jib shall describe a parabola 16 with a vertical axis and in the focus of which is a guide pulley 17 for the suspension cable 14. The jib 6 is mounted on a rotatable cabin 2, the two branches 7 and 8 of the jib being arranged one on each side of the cabin. Each branch carries rollers 9 and 10, the roller 9 moving in a horizontal and rectangular guide 11 and the roller 10 moving in the curved upper guide 12 which is so shaped that the pulley 13 describes a parabola on raising the jib. The distance between the apex 20 of the parabola and the guide 11 is equal to the length of the jib, and the distance between the guides 11, 12 is about one-third of the length of the jib. The jib is connected to a cable 33 on which is suspended a counterweight 32 which passes over a pulley on the same shaft as the guide pulley 17 and moves along a guide 42. The upward movement of the jib is controlled by a shaft 27 connected through a rod and lever 25 and 23 to a roller 9. Alternatively a rack engaging a toothed pinion may be connected to lever 23. The cable 33 is driven by a winding drum of variable radius such that as the jib is raised the load will move horizontally and at constant speed. In a modification, instead of controlling the displacement of the lower end 9 of the jib the displacement is controlled from the point . 10 on the upper guide by means of an endless cable fixed to the jib and driving drum and passing over a guide pulley on the same shaft as a guide pulley 17.
