Abstract: 355,343. Insulators. POLLAK, J. E., 20, Holborn, London.-(Hermsdorf-Schomburg-Isolatoren Ges.; Hermsdorf, Thuringia, Germany.) May 23, 1930, No. 15945. [Class 36.] A chain insulator comprises a pin 5 the head 6 of which is fastened by adhesive to a carrier sleeve 4. A circular ridge 7 on the underside of the pin head 6 rests on a metallic disc 8 which is carried by the sleeve 4, the ridge 7 contacting along the centre line of the carrier sleeve supporting surface. The outer surface of the sleeve 4 and the inner surface of the pin cavity may be roughened or corrugated. The sleeve 4 and disc 7 are put together on the pin shaft, and the pin head 6 is then forged, the ridge 7 being shaped on a lathe, or in a die during the forging. The pin assembly is placed in the insulator cavity and a pulverized mixture 3 of synthetic resin and finely divided china is shaken into position between the sleeve 4 and the cavity wall. The resin is melted by heat and hardened, and lead 9 is poured in between the sleeve 4 and pin 5 to form a protection as shown. In a modified construction the inner wall of the pin chamber and the outer wall of the sleeve are coned so that a wedging action is produced. A pad of stiff paper or material known under the trade name of " Klingerit " may be fitted to the top of the carrier sleeve. A substance known under the trade name of " Trolon may be used as a binding material for the carrier sleeve.

Patent GB-611984-A (GB)
Title: Improvements in and relating to the extraction and purification of streptomycin
Filed: 1946-05-27
Abstract: Streptomycin is extracted from the metabolism fluid of Actinomyces griseus by adsorption on a suitable charcoal (i.e. one which will adsorb streptomycin and yet permit its elution without destroying its activity) under neutral or slightly alkaline conditions, and elution with an aqueous solution of an acid.  Thereafter the eluate is neutralized, the streptomycin is adsorbed again on to charcoal and eluted with acid methanol or ethanol, the eluate is concentrated to one-tenth of its original volume, and a non-solvent for streptomycin salts which is miscible with methanol and ethanol is added to precipitate the salt of streptomycin.  Sulphuric or hydrochloric acid may be used for the first elution, but it is preferable to use phosphoric acid, which makes it possible to carry out this part of the process in stainless steel vessels.  The concentration of the phosphoric acid is advantageously 1-2 per cent, preferably about 2 per cent, though when employing static beds of charcoal the concentration may be reduced in the later stages of the elution.  In an example, the metabolism fluid at pH 8.5 is stirred with activated charcoal (Farnell 14) and filtered with the aid of the material known by the Registered Trade Mark "Supercel," the filter cake is washed with water and agitated with 2 per cent aqueous phosphoric acid, filtered, neutralized to pH 7 and treated with charcoal and filtered as before, the filter cake is washed with water and with methanol and agitated with methanolic or aqueous methanolic hydrochloric acid, the eluate is neutralized to pH 6 and concentrated, and acetone, amyl acetate or monochlorobenzene is added to precipitate streptomycin hydrochloride, which may be further purified by crystallization of the picrate, helianthate or reineckate salts.

Abstract: 1383075 Voltage measuring MICRO CONSULTANTS Ltd 6 April 1973 [7 April 1972] 16190/72 Heading G1U [Also in Division H4] The effect of capacitive coupling C s  between a line or lines 11, 12 shielded by a sheath 14 is reduced by transformer-coupling 19, 18, the sheath with the output of an amplifier 15 connected to the line or lines 11, 12.

IPC: G01B7/06
Filed: 1960-05-09
Abstract: 920,168. Magnetic testing apparatus. SIGMA INSTRUMENT CO. Ltd. May 26, 1961 [May 9, 1960], No. 16234/60. Class 37. A thickness measuring instrument includes a detector, which contacts one side of the test material and has an armature for magnetic cooperation with a magnetic pole of a mechanically separate member for encountering the opposite side of the material, means for applying a controlling force to the armature to counterbalance the magnetic force applied to the armature by the pole, and indicating means responsive to the latter force. Magnet 3, Fig. 1, and point 7 abut against the opposite surfaces of sheet 1 of non-magnetic material, the thickness of which is measured by the vertical movement, with respect to the frame 4, of the magnet 9 suspended by spring 10. A modification, Fig. 2 (not shown), employs a cylindrical magnet held against the underside of the material by the magnetic attraction of a co-operating magnet mounted at one end of a pivoted lever on the other side of the material; the cylindrical magnet rolls over the surface of the material when the latter is moved relative to the apparatus. In a further embodiment, Fig. 3 (not shown), a first magnet mounted on a micrometer spindle is held stationary against the lower surface of the sheet 1, and a frame bearing a pivoted magnet system and scale is located above the first magnet by seeking the position of minimum scale reading; in this position the instrument can be calibrated by adjusting the micrometer to the appropriate reading with a known thickness of material, the micrometer reading corresponding to adjustment to return to the same scale reading subsequent to the introduction of the test material giving the thickness of the latter. Reference is made to the use of an air jet for applying the controlling force to the armature. The Provisional Specification refers to mechanical, electrical, or optical amplification of the armature movement, to the use of the detector unit for the location of iron pipes in brick walls, and to the use of the position of unstable equilibrium of opposed magnetic and spring forces for the indication of a minimum thickness. The Provisional Specification further refers to an instrument in which the detector unit and the member for encountering the opposite side of the test material are mechanically connected by a magnetic leafspring.
