Title: Improvements relating to the working of steam power plants involving long pipe lines
IPC: F01K17/00
Filed: 1928-06-29
Abstract: 295,575. Akt.-Ges. der Maschinenfabriken Escher, Wyss, et Cie. Aug. 13, 1927, [Convention date]. Automatic gear.-A steam-power plant supplying steam for auxiliary purposes through a long pipe to the place of consumption is so controlled that when the steam consumed is varied, the pressure of steam taken from the engine is sc varied that the pressure of steam where consumed is approximately constant. The change in the back or bleed-steam pressure may be obtained by varying the steam passing through the engine in dependence on the steam pressure in the vicinity of the consumer. The steam passing through the engine may also depend upon the pressure directly behind the engine or on the pressure at the tapping-point. The steam supply may also be varied by the quantity of steam passing to the consumer and by the pressure therein or by the back or bleeder pressure immediately behind the engine. In the construction of bleeder steam turbine driving a generator G shown in Fig. 1, the supply depends upon the pressure at 7 adjacent the consumer V which affects the line steam valve 1 of the high-pressure element H. Steam tapped at 4 passes through a long main 5 wherein considerable pressure drop occurs to the consumer V. A governor-controlled bye-pass 2 is placed between the stages H, N. In a modification, the turbine exhaust supplies the consumer. The pressure adjacent the engine and a velocityoperated Venturi-meter control the valve 1. In the construction shown in Fig. 3, the turbine supply valve 1 is controlled by the pressure at the consumer in pipe 10, and by the pressure at a point 11 behind the, engine. The pressure at 10 controls a switch 13 which affects a motor 14 supplied from a source 15. The pressure at 11 affects a diaphragm 26 and thereby a lever 16 which carries a plate 17 controlling a nozzle 18 of a fluid-pressure chamber 19 the pressure in which affects the valve 1. The motor 14 through gearing 23, 24 regulates the spring 25 acting on the lever 16.

Abstract: 570,940. Gear-cutting. AEPPLI, A. Nov. 16, 1943, No. 19080. Convention date, Nov. 16, 1942. [Class 83 (iii)] An indexing-device for machines for grinding gears of comparatively large diameter comprises a feeler member which, after rough indexing has been carried out, enters a tooth space on a dividing wheel which rotates with the work, and co-operates with an indicator by the aid of which an accurate angular adjustment of the work-table may be made. The gear 11 to be cut is mounted on a table 12 which is rotated by a handle 21 through gearing 15-20 and rough indexing is effected by means of a disc 24 having a recess 25 adapted to be engaged by a dog 27 on a spring-actuated lever. One, or a number of complete rotations of the disc 24, which is driven from the handle 21 by gears 20, 22, corresponds approximately to a rotation of the work by one tooth. The work-table carries a dividing-wheel 14, the number of teeth on which is equal to or is a multiple of the number of teeth to be cut on the work. After rough indexing, a slide 29 carrying a pivoted lever 30 is moved by means of a screw 34 and handle 33 so that a spherical head 31 at one end of the lever enters a tooth space of the wheel 14 and at the same time a bolt 36 operated through levers 37, 38 enters an oversized hole in a disc 35 associated with the disc 24, to lock the work-table against all but comparatively small movements. The other end of the lever 30 co-operates with an indicator 32 to show when further slight movement of the work-table by means of the handle 21 has brought a tooth space to the exact position required. The reading of the indicator 32 may be periodically checked by means of a template 39 which can be brought into position as shown in Fig. 4, a drum 43 on the shaft of the. screw 34 serving to prevent a movement of the template while it is engaged by the head 32. The invention is described as applied to a machine in which a vertical slide 6 of the grinding-wheel 7 is carried by a standard 5 mounted on a table 2 rotatable about the axis of the work by means of a screw and nut 4. 4'. An extension 10 on the standard is connected to a fixed cylindrical surface 8 by means of flexible-band rolling-mechanism.

Title: Isonovobiocin and the conversion of isonovobiocin to novobiocin
IPC: C07H17/075
Filed: 1958-06-16
Abstract: The invention relates to isonovobiocin which is an isomer of novobiocin in which the carbamyl group is in the 3-position instead of the 4-position.  Novobiocin has the formula <FORM:0878907/IV (b)/1> Isonovobiocin is present in crude novobiocin and is biologically inactive.  An aqueous solution of isonovobiocin at pH 9.5 to 11 on standing forms an equilibrium mixture containing two parts of novobiocin to one part of isonovobiocin.  Crude novobiocin is therefore purified by treatment with aqueous acetone of 55 to 80, and especially 60% by volume in order to remove isonovobiocin preferentially to novobiocin, the resulting extract containing a mixture of novobiocin and isonovobiocian in a ratio of less than 1 e.g. two or more parts of isonovobiocin per part of novobiocin. An aqueous solution of a water-soluble alkali such as sodium carbonate, sodium hydroxide, potassium hydroxide and potassium carbonate is added to (a) the aqueous extract or (b) the solids obtained from the extract to produce a pH of 9.5 to 11.0 and the solution is allowed to stand at 15 to 35 DEG C. until the equilibrium mixture is obtained. The solution is acidified to pH 1.5, acetone added, and novobiocin crystallised therefrom.  Isonovobiocin may be obtained pure by the countercurrent distribution of crude isonovobiocin in the solvent pair obtained by combining water, acetone, methyl ethyl ketone and n-hexane in the proportions 3 : 9 : 2 : 6 parts by volume.  Treated with methanolic hydrochloric acid isonovobiocin is degraded to 2-O-carbamyl-4-O- methyl-5,5- dimethyl-L- lyxose which is not oxidised by periodic acid.  Specification 832,140 is referred to.
