Abstract: 344,092. Lightning arresters. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Hull, A. W.; 1021, Waverly Place, Schenectady, New York, U.S.A.) Dec. 11, 1929. No. 38031. Convention date, Dec. 27, 1928. [Class 38 (iv).] A lightning arrester has a gastight envelope 1 enclosing a pair of non-thermionic electrodes 8 of a material vaporized with difficulty, the envelope being evacuated to a pressure of the order of one micron and occluded gases being removed from envelope and electrodes, so that a discharge between the electrodes is substantially unaccompanied by gaseous ionization. Suitable electrode materials are tungsten, graphite, aluminium and copper. The discharge starts as a pure electron discharge and changes to a vapour arc. The electrodes preferably have convex surfaces with a radius of curvature greater than the space between them. A filamentary electrode may be mounted within the envelope for use in freeing the arrester electrodes from occluded gas. The envelope may have transverse corrugations 25 to increase the discharge path over the envelope and pant legs 26 may surround the electrode stems. The device may be connected between line and ground directly, or in series with a low resistance, or in series with a resistance equal to the surge impedance of the line. In the last case a resistance is preferred which increases under current with a high power of the applied voltage, such as that described in Specification 292,110, [Class 38 (iv), Electric supply and transmission systems &c.]. Several arrester units may be arranged in series by means of hookshaped terminals between a conductor and a support, one or more being arranged to break down before the others for example by the use of a condenser in shunt to one of them. The invention may be used to bridge the contacts of a switch controlling a circuit subject to surges. Specification 245,221, [Class 38 (iv), Electric supply and transmission systems &c.], also is referred to.

Abstract: <PICT:1077999/C2/1> Antibiotic 235A effective against gram negative micro-organisms is produced by cultivating an antibiotic 235A-producing micro-organism of the species Streptomyces Lavendulae or Streptomyces avidinii in an aqueous nutrient medium.  The micro-organism is preferably Streptomyces avidinii MA 833 (NRRL 3077) or Streptomyces lavendulae MA 669 (NRRL 3076). Antibiotic 235A has two components antibiotic 235S and 235L, these are recovered by contacting an aqueous solution containing antibiotic 235A (or a mixture of antibiotics 235L and 235S) with a strongly acid cation exchange resin to absorb a major portion of 235S and a minor proportion of 235L, collecting the effluent and recovering 235L, e.g. by precipitation with ammonium sulphate; eluting the resin adsorbate with dilute ammonia and recovering 235S from the resulting eluate, e.g. by subjecting the eluate to dextran chromatography, eluting with water and recovering 235S and the minor proportion 235L for separate selected eluate fractions or extracting the eluate with n-butyl alcohol and recovering 235S from the resulting extract or dialysing the eluate and recovering 235S from the resulting dialysate, the minor proportion of 235L remaining in the residue.  The antibiotics 235S and 235L may be further purified by reabsorption with a strongly acidic cation exchange resin (235S) and dialysis followed by dextran chromatography (235L).  Antibiotic 235L (Streptavidin) is a crystalline solid m. pt. 223-230 DEG  C. and is a polypeptide containing C 51.1%, H 7.4%, N 16.4%, S 0.2% and O 24.9% of mol. wt. about 60,000 and U.V. absorption maxima at 282 mm  (E1% = 47). Antibiotic 235S has by paper chromatographic procedures been separated into three components, 235S1, 235S2 and 235S3.  Antibiotic 235S2 gives a positive biuret reaction and on acid hydrolysis yields an amino acid product of RF 0.52 in 100 parts n-butanol, 12 parts acetic acid and 100 parts water.  Antibiotic 235S3 is a primary amine, forms salts with acids, is soluble in water, lower alcohols and aqueous acetone, has m. pt. 217 DEG  C., gives a negative biuret reaction and contains C63.1%, H 8.9%, N 13.04%, O 14.96%, mol. wt. 322, possible molecular formula C17H28N3O3, is optically active [a ]25 = +8.5 DEG  (C, 2 in 0.1 N HCl) and [a ]25D = 9.5 (C, 2 in 3.5 NHCl) and has I.R. spectra in mineral oil as shown in the drawing. Antibiotics 235S1, 235S2 and 235S3 are characterized by the property of inhibiting the intracellular synthesis of biotin in gram negative micro-organisms.  The individual components of 235A have no antibiotic activity and thus 235A is composed of a synergistic pair of substances 235S and 235L.

Abstract: 1379136 Internal shoe drum brakes; trailer brakes H EBERHARDT [trading as PEKAFAHRZEUGBAU EBERHARDT KG] 23 Aug 1972 [23 Aug 1971 21 Feb 1972 11 July 1972] 39254/72 Heading F2E In a shoe-drum wheel brake especially for road vehicle trailers having an arrester braking system, a counter-pressure for one of the brake shoes on the end opposite the point of application of the brake-actuating force is provided by a spring which yields when a predetermined value of the brake power is reached and allows a displacement of the brake shoe in a peripheral direction, the direction of the spring force being that of a line connecting the unactuated ends of the two brake shoes, and the other brake shoe has a fixed seating which is adjustable in position. As shown in Figs. 1, 2 and 5, shoes 2, 3 are applied by cable and split levers 6. The lower end of shoe 2 abuts a slider 10 accommodating a compression spring 11 which is restrained at its further end by a wedge 9 adjustably located in the brake anchor plate 1. The spring compression may be adjusted by a screw 12. Housing 7 is fastened to anchor plate 1 and accommodates, besides slider 10, a further slider 8 which engages shoe 3 and is adjustable in position by wedge 9. Stops may be provided to limit the sliding movements of sliders 8 and 10. In operation, when the brakes have been applied, and as soon as a certain braking power (related to the vehicle axle weight and set by screw 12) is reached, spring 11 yields, so brake shoe 2 moves peripherally: the counter-pressure thereon is thereby reduced and the brake power cannot increase further. The setting of screw 12 may be such that little or no limitation of braking power takes place during forward movement while during reverse movement the brake power is smaller or zero; the invention is thus applicable to trailers. In Fig. 10, the slider 10 is replaced by a shear lever 28, pivoted in a fixed yoke 27 and acted on by a spring 24 adjustable by a screw 32. Preferably the shear lever incorporates two stops: 33, serving as a limit stop for spring 24 and also determining the zero position of shoe 23, and 34, defining the limit of movement of shoe 23 when it is moving peripherally as above described. Shear lever 30, for shoe 22, has a resetting screw 29. The brake shoe webs may be protected by clips made of material harder than the brake shoes, where they make contact with the shear levers (Figs. 11, 12, not shown). The shear lever-spring arrangement of Fig. 18 resembles that of Fig. 10. Manual wear-adjusting.-The wedge 9 and slider 8 of Fig. 5, and the shear lever 30 and screw 29 of Fig. 10 provide for wear adjustment of shoes 3 and 22 respectively. In Fig. 18 and (slightly modified), Fig. 13, the left-hand shoe bears via a recessed and slotted slider on a rotatable eccentric. Return springs 73, Fig. 17, are hooked to the brake shoes at 74, 75, and the upper one is located in a clip 76 secured to the anchor plate 1, to prevent lateral displacement of the spring.
