Title: Improvements in or relating to the sintering of beryllium
Inventor: BUTCHER JOHN WILLIAM
IPC: C22C1/04
Filed: 1963-10-07
Abstract: In a process for hot pressing cast beryllium powder the inert non metallic barrier layer on the surface of the beryllium particles which prevents the formation of metal to metal bonds is overcome by adding sufficient silicon e.g. 190-1200 p.p.m. to produce a valency imbalance in the barrier layer and promote the diffusion of beryllium. The silicon may be added as a powder and a mixture formed by ball milling, or the silicon may be introduced into the beryllium by decomposition of the vapour of a silicon compound such as silicon oxide or trichlorosilane.  In an example a graphite mould is coated with ethyl silicate and dried.  The beryllium powder is hot pressed in the coated mould at 1000 DEG -1200 DEG C., 1 ton p.s.i. under a vacuum of 70 m  Hg maximum. In this process the ethyl silicate liberates silicon dioxide from which silicon is deposited up to 1200 p.p.m. of silicon may be added according to the surface area of the beryllium.

Title: Production of actinomycins f and f by fermentation
Filed: 1957-12-19
Abstract: <PICT:0832032/IV (b)/1> Actinomycin F1 and actinomycin F3 are produced by cultivating an actinomycin C producing-strain of Streptomyces chrysomallus in an aqueous nutrient medium containing sarcosine or a sarcosine producing compound such as sarcosine amide, sarcosine alkyl ester, sarcosyl sarcosine or N,N1-diketopiperazine. A suitable medium contains glycerol, sarcosine, potassium nitrate, potassium phosphate, sodium chloride, calcium carbonate, magnesium carbonate, ferrous sulphate and water.  In the example, a mixture of actinomycin is dissolved in benzene and passed through a column of alumina saturated with benzene.  The column is washed with 60/40 benzene/ethyl acetate to produce three zones which are eluted separately with further solvent except that in the case of the top zone elution is by means of ethyl acetate. After removal of the solvents, the solids are dissolved in acetone and petroleum ether added to precipitate the actinomycins.  When developed on a paper chromatogram treated first with an aqueous phase of a mixture of 5% di-n-butyl ether, 35% di-n-propyl ether, 10% butanol and 50% of an aqueous solution of sodium m-cresotinate and then with the organic phase of this mixture, zone (1) (lowermost in column) contains actinomycins C1, C2 and C3; zone (2) (middle layer) contains actinomycins F2 and F4 and zone (3) (upper layer) contains actinomycins F1, F2, F3 and F4.  Cellulose powder in a column is treated with the aqueous phase of a mixture of 10% di-n-butyl ether, 27% di-n-propyl ether, 13% butanol and 50% aqueous sodium m-cresotinate and then with the organic phase, a solution of the above zone (3) in the organic phase is passed down the column and four zones develop.  On elution, there is recovered actinomycins F1, F2, F3 and F4. Actinomycins F1 and F3 are less toxic than known actinomycins C1, C2, C3I and X but have the usual cytostatic activity; they crystallize in rectangular platelet form and contain .F1.F3 Carbon.56.8.57.85 % Hydrogen.7.35.7.29 % Nitrogen.13.05.9.55 % On hydrolysis with hydrochloric acid for 24 hours at 100 DEG  C F1 produces threonine, sarcosine, valine, isoleucine and N-methylvaline whereas F3 produces threonine, sarcosine, isoleucine and N-methylvaline.  In ethanol the ultraviolet absorption of actinomycin F1 shows lambda max. 238 mm , d=29.3 and lambda max. 447 mm , d=19.8 (Fig. 1), for actinomycin F3 it shows lambda max. 238 mm , d=27.6 and lambda max. 447 mm , d=18.5.  The infra-red spectrum of actinomycin F1 is as shown in Fig. 2 (maxima at 2.95, 3.4, 5.75, 6.05, 6.35, 6.65 and 6.75 m ) and for actimomycin F3 it is as shown in Fig. 3.

A liquid fuel atomizer comprises an annular wall 18 adapted to intercept a variable proportion of the cone of fuel spray from a swirl chamber 12 at the end of an inner barrel 10 and an adjustable cap 32 arranged to transmit axial movement to the inner barrel 10 to vary the distance between the outlet 13 of the swirl chamber and the annular wall 18. The annular wall 18 is part of a member 17 screwed on to a fixed outer barrel 16 and has a V-shaped groove 50 on its outer surface. The fuel intercepted by the annular wall 18 flows between the barrels 10, 16 to an outlet 21 and is pumped to a point in the fuel supply system between a heater and the inlet 11 to the inner barrel 10. The adjustable cap 32 is threaded on to a body member 33 screwed on to the outer barrel 16 and has an adjustable stud 38 in abutment with the plugged end of the inner barrel 10. A helical spring 45 urges the inner barrel 10 into engagement with the stud 38 and a flange 46 on the inner barrel acts as a stop to limit rearward movement of the inner barrel. The fuel inlet 11 leads to a chamber 39 in the body 33 and the fuel flows through holes 44 into the inner barrel 10. The sprayer nozzle on the end of the inner barrel 10 comprises a sprayer plate 14 containing the swirl chamber 12 and a distributer plate 15 forming the rear wall of the swirl chamber 12 and having passages extending between annular recesses 26, 27 on its rear and front surfaces. Slots in the rear surface of the sprayer plate 14 convey the fuel tangentially into the swirl chamber 12. The sprayer and distributer plates 14, 15 are clamped between an inner sleeve 23 welded to the end of the inner barrel 10 and an outer sleeve 22 screwed on to the inner sleeve 23. The outer sleeve 22 is a sliding fit in the fuel interceptor member 17 and has six channels 30 for the flow of the intercepted fuel. The axial movement of the inner barrel 10 may be effected by a fluid pressure acting on a bellows and related to steam pressure. Provision may be made for varying the pressure of the fuel supply and therefore the angle of the cone of spray.

Title: Improvements in or relating to electric control arrangements for forging presses
IPC: B30B15/16
Filed: 1959-11-25
Abstract: 897,560. Forging presses. LIPPKE, P. Nov. 25, 1959 [April 18, 1959], No. 40033/59. Class 83 (4). [Also in Group XXIX] A control arrangement for a forging press, comprises a contact arm 16 connectible to a moving member of the press, such as the piston, during final forging and co-operating with contact members 17, 18 for reversing the press at the appropriate stroke position. During initial forging on an hydraulic press, the stroke is controlled by a manually-operated potentiometer 1 which forms a bridge circuit with a follow-up potentiometer 2 mechanically coupled to an hydraulic setting-piston 3 controlling the main valve of the press. The output of these potentiometers is fed through an amplifier 4 to a slide valve 5 controlling the setting piston 3. A switch 14 actuated by the press piston and a switch 15 actuated by the potentiometer stop the press, during initial forging, when a desired workpiece dimension is attained. For final forging a switch 7 cuts out potentiometer 1, inserts resistances 8, pre-set by switch 9, for controlling the length of stroke and energizes a magnetic coupling 11 which couples the contact arm 16, Fig. 2, with a pinion 13 driven by a rack 12 connected to the press piston. Movement of the latter on the press stroke causes the contact arm 16 to move round the various contact members 17, 18 which so control the resistance 8 that the amplifier 4 causes valve 5 and piston 3 to reverse the press at both ends of a predetermined stroke. Contact 18 initiates the return stroke and the preselected contact 17 initiates the forward stroke. A return-spring 19 biases the arm 16 towards the contact 18 which ensures that final forging always begins with a return stroke. An hydraulic or preferably an electric motor 20 is used to rotate the contacts for varying the stroke position. The contact arm may have rectilinear movement instead of rotary.
