Title: Transistorised amplifier with automatic gain control
IPC: H03G1/00
Filed: 1957-06-07
Abstract: 807,815. Transistor amplifiers. STANDARD TELEPHONES & CABLES Ltd. June 7, 1957 [June 13, 1956], No. 18245/57. Class 40 (6). Automatic gain control in a multistage transistor amplifier is effected by deriving a control signal from the output of the amplifier and using it to control the effective resistance in series with the emitter electrode of the input transistor in such a manner as to maintain the output of the amplifier substantially constant. The transistors used may be of either the junction or point-contact type. In Fig. 1 a unidirectional control current derived by rectifiers 40 at the output of the amplifier is applied to a circuit comprising diode 30 to vary the impedance reflected by the diodes 30 through the transformer T2 in series with the emitter electrode of the first-stage transistor. Fig. 2 shows a modified circuit in which the control circuit is used to vary the resistance of a directlyheated thermistor 50 having a positive temperature coefficient. The circuit may be modified to employ a thermistor with a negative temperature coefficient by returning the thermistor to a point of suitable bias potential. In Fig. 3 the output signal of the amplifier is used directly (i.e. without rectification) to control the resistances of thermistors 50<1> coupled through transformer T2 into a series circuit with the emitter electrode of the input transistor.

An antibacterial, antifungal, antibiotic libanomycin, which also has growth factor properties in the human and veterinary field, is produced by the aerobic cultivation of a libanomycinproducing strain of Streptomyces libani n.sp. in an aqueous nutrient medium containing assimilable sources of carbon, nitrogen and mineral salts at pH 5 to 8À8. The strains specified are F.I. 2343 (I.M.I. 130777 and I.M.R.V. 3915), F.I. 2399 (I.M.I. 130778 and I.M.R.V. 3916), F.I. 2501 (I.M.I. 130779 and I.M.R.V. 3917) and F.I. 2521 (I.M.I. 131233 and I.M.R.V. 3918). Libanomycin is a complex of components A, B and C. Crude libanomycin is isolated from the mycelium and also from the clarified broth. The mycelium is extracted with aqueous alcohol or. aqueous acetone and the extract is concentrated to precipitate the crude complex. The clarified broth is extracted with butyl alcohol at pH 7À5 to 8À5, the butanol extract concentrated and the crude antibiotic precipitated by the addition of acetone or diethyl ether. Alternatively, the antibiotic may be adsorbed on a carboxylic cationic exchange resin in the acid form. The resin is washed with water and then with 0À5 N NH 4 OH and the antibiotic is eluted with alcoholic aqueous saline, e.g. NaCl in aqueous CH 3 OH and the eluate concentrated and extracted with butanol. The crude is dissolved in alcohol and the solution is chromatographed on a column of neutral activated alumina or silica gel. Alcoholic elution fractions containing B, A and B and A and C are obtained. These fractions are further purified by chromatography on cellulose powder followed by elution with butanol: pyridine: water (6:3:4). Soluble in aqueous alcohols, aqueous acetone, methanol, ethanol, pyridine, dimethylformamide and dimethylsulphoxide; sparingly soluble in water; insoluble in acetone, chloroform, benzene, diethyl ether and petroleum ether. A pharmaceutical composition for oral or parenteral use comprises one or more of the antibiotics libanomycin complex and its components A, B and C and a carrier. The antibiotic (including mycelium) may be incorporated in animal feeds as a nutritional supplement.

Abstract: 293,314. British Thomson-Houston Co., Ltd., (Assignees of Thomson, D. P.). July 1, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Dynamos and motors, cooling.-An enclosed machine is provided with (i) a thin end wall having good thermal conductivity and an opening of slightly larger diameter than the shaft, and (ii) a fan on each side of and closely adjacent to the end wall to force over its surfaces and convey heat from the air enclosed in the casing to the air which is circulated over its outer surface. In the form shown, the stator frame is enclosed by a ring 20, a thin partition wall 32 and a head piece 21 which carries the bearing. The ring has a series of wide peripheral slots 28 enclosed by a band 29 and formed with constrictions 30 which act as jets to direct the air from inlets 24 in the head and an external fan 40 axially over the outer surface of the casing. The partition 32 is secured to the ring 20 by screws 33 and is stiffened by riveted ribs 34. It may have a running clearance around the shaft or a packed joint may be employed if greater tightness is required, for instance as in machines used in chemical works. The internal air passes, as shown, through openings 11, 12 under the armature and commutator; a fan 36 is employed with its blades cut away to surround the ends of the windings. Both fans are shrouded, at 41, 37, and are mounted close to the partition 32 to prevent foreign matter in the air from accumulating on the plate. The shrouding 41 of the outer fan lies close to a plate 25 secured to the head on the inner side of the inlet openings 24 and both shroudings are at substantially the same distance from the shaft so that the zones of air which moves with the highest velocity over the inner and outer surfaces of the partition 32 are at substantially the same radial distance from the shaft, thus giving the maximum transfer of heat.
