Title: Improvements in or relating to calculating mechanism
IPC: G06G3/00
Filed: 1924-11-20
Abstract: 247,314. Legros, L. A. Nov. 20, 1924. Logarithmic apparatus. - ,Calculating mechanism of the kind which enables the value of a function of two variable quantities to be indicated comprises a differential gear, two of the wheels of which are each coupled to the driven sector of a pair of interengaging toothed cam-like members to impart an angular movement to the wheels proportional to the logarithm of the angular movement of the driving sectors. As shown in Figs. 1, 2, and 3, applied to a motor vehicle for giving the rate of fuel consumption in miles per gallon, the indicating spindles 10, 12 of the two measuring instruments are coaxial and drive through gearing 13, 14, 19, 20 respectively the logarithmic spiral sectors 16, 22. The sector 16 gears with a similar sector 17 rotatably mounted on a spindle 11, Fig. 3, but integral with a sun wheel 18 gearing with a pinion 30 of a pair of planet wheels 30, 32 secured to a spindle 28 in a differential gear frame 26 freely mounted on the spindle 11. Similarly the sector 22 through a sector 23 and pinion 24 drives a pair of planet wheels 29, 31 on a spindle 27 in the differential gear frame. A flexible connection 42 consisting preferably of a bent elastic link of spring or wire serves to maintain engagement of the camgears. The gear frame 26 and the spindles 10, 12 carry indicating drums 33, 38, 39 respectively for co-operation with a fixed index line extending across the reading aperture 40, Fig. 2; the drum 33 is graduated logarithmically .and the drums 38, 39 uniformly. As an alternative. the frame and spindles may carry pointers movable over fixed graduated drums or dials arranged on separate spindles. In the latter case where the graduations do not follow in uniform divisions a variable motion gear 53, 55, Fig. 5, is utilized to transmit uniform increments of movement to the driving sector. The condition to be observed in forming the teeth of the sectors is that the teeth must touch on the pitch line at the point midway between the centres of rotation, a shrouding extending to the pitch line being formed at one side to ensure the proper meshing of the interengaging sectors. A servomotor or " follow up " device may be employed to drive the mechanism from one or both instruments. Such a device is shown in Fig. 9 wherein the spindle 10 carries an arm 62 provided with two brushes 63 adapted to co-operate with a drum 64 having two pairs of contacting segments 68 - - 71, in circuit with a source of current 79, and a pair of solenoids 84, 85. The arm 82 of the solenoids rotates a commutator drum 76 on which bears two pairs of brushes 74, 75, 80, 81 respectively connected to the brushes 73 of the armature winding of a motor 67 and to the source 79. The motor 67 through worm gearing 65, 66 drives the drum 64 in one or other direction. Specification 194,124 is referred to.

Title: Improvements in or relating to antibiotics
Filed: 1951-11-28
Abstract: An antibiotic effective against Mycobacterium tuberculosis is produced by the aerobic fermentation of Streptomyces aren  NRRL 2377, the cultural characteristics of which are described, in an aqueous nutrient medium.  Specified carbon sources are xylose, glucose, mannose, galactose, lactose, maltose, sucrose, mannitol, glycerol, sodium acetate, sodium citrate and potassium sodium tartrate. Nitrogen sources are sodium nitrate, diammonium o-phosphate, urea, asparagine, tryptophane and arginine.  In the example, a nutrient medium containing yeast, cornsteep, glucose, soybean meal, sodium chloride, ammonium nitrate, calcium carbonate and water is inoculated with a preculture of Streptomyces aren , and agitated at 220-240 r.p.m. for 2 to 7 days at a temperature of 24-26 DEG  C.  The mycelium contains 90-95 per cent of the antibiotic activity.  The antibiotic may be extracted from the mycelium with 50-80 per cent aqueous ethanol at pH 4-10 and preferably pH 7, the ethanol removed and the aqueous residue extracted with butanol at pH 2-4.  The butanol extract is treated with water at pH 10 and the butanol water process repeated. Methanol, acetone, butanol and tertiary butanol may be used instead of ethanol.  Alternatively, the aqueous extract obtained after the removal of ethanol may be extracted with chloroform at pH 2-10 and the chloroform extract chromatographed first on (a) anhydrous silica gel and then on (b) magnesium silicate, the antibiotic being eluted with a mixture of methanol and chloroform.  An activated carbon adsorption step may also be used. The antibiotic is a mixture of at least two components.  It is acidic forming alkali metal salts, e.g. sodium, which is soluble in water, and the copper, calcium, magnesium and lead salts, which are insoluble; molecular weight is approximately 10,000; shows characteristic peak in ultra-violet absorption spectrum at 260 mm , and characteristic absorption bands in infra-red at 1008, 1100, 1121, 1282, 1739 and 3390 when suspended in a hydrocarbon oil; contains C, H, N and S.

Abstract: 319,220. British Thomson-Houston Co., Ltd., (Assignees of Emmet, W. L., and Coulson, B. P.). Sept. 17, 1928, [Convention date]. Mercury boilers.-The boiler comprises units 4 connected in parallel to a drum 6 which is connected ta. a rear drum 9 by pipes 8 arranged to allow for expansion of the vapour supply pipe 10. Each unit comprises a drum 13 the heads 14, Fig. 7, of which engages a tapered seat 15 therein. The drums 13 have grooves containing rings 20, split or in section, which are locked by rings 21 and engage shoulders 16, 17 on the drums and heads respectively. Yieldable U-shaped sealing- rings 22 are welded to the drums and heads. Boiler tubes 23, Fig. 5, with rounded bottoms and tubular cores 24 depend from the drums 13 to which they are welded. The cores 24 are spaced from the tubes 23 by ribs 26 and projections 27 and comprise tubes 30, 31 welded together with an air &c. insulating-space between them. Relatively cool mercury is thereby delivered to the bottom of the tubes 23 and is heated by radiation. Tubes 30 are curved to permit relative expansion. The upward floating of the cores due to their immersion in mercury is prevented by washers 33, Fig. 4, welded to the tubes. A sectional, perforated, baffle plate 36 is spaced from the lower surface of the drum 13. Slidable sleeves 40 in the plate connect the interior of the drum 13 and the cores 24 as described in Specification 319,219. The passages 39 are arranged in staggered formation in longitudinal lines. Filter blocks 45 are secured in the drum 13 in spaced relationship to the plate 36 to decrease the liquid required. Small change in the liquid bulk thereby produces large change in the liquid level. Supplementary filler blocks 49<a> surround the sleeves 40. Baffles 50 prevent priming. The boiler units have liquid-level gauges comprising sealed casings 60 housing floats 61 connected to blocks 64 of magnetic material. A horseshoe magnet 66 pivoted on a weighted lever 67 surrounds the end 65 of the tube enclosing the block 64, one arm passes in front of a scale 72. The boiler tubes 23, Fig. 6, are flared to absorb heat and the circulation of the combustion gases is effected by baffles.
