Patent GB-692131-A (GB)
Title: Improvements in or relating to the recovery of aureomycin
Filed: 1951-08-22
Abstract: Aureomycin is recovered from solid aureomycin-containing material by extracting said material at least once with an aliphatic alcohol of 1-6 C atoms at a pH below 4, separating the extract from the solids, and recovering the aureomycin from the extract.  It is preferred to use an alcohol, e.g. n-butanol, which is substantially immiscible with water and is wet, a pH of 0.5 to 2.5 and an extraction temperature of 10-55 DEG  C.  The extraction may be batch or countercurrent.  The acid used may be hydrochloric, sulphuric, phosphoric or acetic.  The aureomycin is recovered by removing the alcohol in vacuo below 55 DEG  C. until the aureomycin starts to precipitate from the concentrated extract, which is then cooled, preferably after adjusting the pH to 0.8. The crystals are washed with at least two of the following solvents used in succession; namely n-butanol, b -ethoxyethanol, ethyl alcohol and water.  If aureomycin hydrochloride is desired, and an acid other than hydrochloric acid is used in the original acidification, the extract is shaken with a saturated solution of sodium chloride.  The solid aureomycin may be the alkaline cake obtained from a fermentation mash by adding certain bivalent metal ions, e.g. barium and strontium, and adjusting the pH to 7 to 8.5.

Title: Process for the purification of ª-aminolactams
IPC: C07D201/16
Filed: 1967-05-01
Abstract: a -Aminolactams are purified by passing a solution of the a -aminolactam in a polar solvent in the presence of ammonia over a cation exchanger, and subsequently passing the solution, optionally in the presence of ammonia, over a strongly basic anion exchanger and recovering a solution of the a -aminolactam of enhanced purity.  The a -aminolactam is suitably passed over the cation exchanger at 50-60 DEG  C. and over the anion exchanger at 15-25 DEG  C., suitable solvents being water, methanol, ethanol and butanol.  If the solution of the lactam to be purified contains iron, this is preferably removed before passage of the solution over the cation exchanger by oxidizing, e.g. with air or H2O2, the iron to the trivalent form and separating out the resulting precipitate of the ferric compound.  The aminolactam starting materials may be obtained by the catalytic hydrogenation of the corresponding a -nitrolactams.

Patent GB-455060-A (GB)
Title: Improvements relating to electric gas-blast circuit-breakers
IPC: H01H33/91
Filed: 1935-07-13
Abstract: 455,060. Fluid - blast switches. RUPPEL, S., 3, Alexander-Ufer, Berlin. July 13, 1935, No. 20097. Convention date, July 13, 1934. [Class 38 (v)] In a gas-blast switch employing gas at lower pressure to extinguish arcs due to normal loads and gas at higher pressure to extinguish arcs due to overloads, the gas at the lower pressure is derived from a mechanical compressor which is actuated when the switch is opened. Air, hydrogen, or carbon dioxide may be employed and may be in liquid or solid state. For the normal-load break handoperated compression means may be employed, whereas for the overload break, the overload electromagnets may drive a reciprocating compressor, or the current may produce gas by chemical reaction. The overload point may be opened by the gas-pressure produced by the arc at the normal-load break. In Fig. 1, the normal break is at 1, 3 and the overload break at 2, 4, the movable pin fitting in a gland 33 in an orifice 34, and the pin 4 closely fitting in contact 2. To open a normal load, the spring 22 acts on a piston 16 which compresses gas in the cylinder 15 and chamber 5 and then releases the opening spring 14. To open an overload, this separation of 1, 3 may be made to occur first. The overload release then moves a slide valve 24 to allow gas from the cylinder 23 to traverse pipe 27 and move the operating piston 29, and also to pass into chamber 5 and act on the arc set up between 2, 4. The current causing the latter arc will already be reduced, due to the are at 1, 3 being cooled by the restriction 34, so the arc at 2, 4 is soon extinguished. The pin 4 may be reclosed by a spring when the gas-pressure subsides. The container 23 may be large enough to serve for several reclosures, or it may be only large enough to serve for one reclosure, in which case it is connected by a pipe 31 with a main container. Gas for closing the switch 2, 4 is admitted to cylinder 28 by way of a pipe 30. In Fig. 2 (not shown), a single break is provided, and is acted upon by gas supplies admitted through separate valves to the switch chamber. A somewhat similar form is shown in Fig. 3 in which, on normal loads, the pin 3 only moves and gas is admitted to chamber 40 by valve 37, whereas on overload the contact 4 is also moved and gas is admitted to chamber 44 by pipe 39 and flows round the pin 4 and also passes inside it through opening 41. The supply from 39 may be omitted and the arc extinguished at 34 due to the blast of heated gas set up by the part of the arc which is located in chamber 44. This action may be increased by pressure set up by vapour or gas given off by substances when heated by the arc.

Abstract: 301,519. Waller, P. H. Aug. 2, 1927, Road-traffic signals on vehicles.-Relates to appuratus in which the signal is first operated by a manual switch retained by electromagnetic means, this control being subsequently released and taken over by a switch operated by the steering gear, and consists in providing a manually operated master element constructed so as to constitute itself a retaining electromagnet when moved to make a signal circuit which electromagnet is de-energized when the element is cut out of the signal circuit or the latter opened. A hand lever 3 pivoted on a universal joint 1 in a casing 2 carries a coil 4 and is under the action of return springs 5, 6 which tend to keep it in normal position. The signal circuits are made by moving the lever so that one of the contacts 8 - - 11 carried by the lever engages the corresponding contact of a series 12 - - 15 connected to signal circuit, terminals 17 - - 20, thus causing the signal to be given and energizing the coil 4 by means of which a surrounding ring 7 becomes a magnet and retains the lever in the signal position until the coil 4 is de-energized when the signals are taken over by an automatic control as for example those described in Specification 301,521.

The cell carburetters have a fuel nozzle 12 supplied through a valve 11 and may include an enriching fuel nozzle, and ultrasonic generator and mixing baffles. The throttle may be arranged to be either open or closed or operable to a half-open position. Fig. 12 shows a wick type carburetter having a central fuel resevoir connected to an annular fuel channel 102a. A series of wicks 125 extend into the air passage of the series of cell carburetters 105. The wicks may be of porous rod or a bundle of capilleries. The cell carburetters are of the rotor valve type and may have secondary air passages 105b operable when the solenoid 108 rotates the cell carburetter body through 90 degrees so closing the main air passage 105a. The solenoid operates through a one way electromagnetic clutch 107. The carburetter may have baffles 126 or an ultrasonic generator to aid mixing. The cell carburetters may be arranged to promote swirl Figs. 14 and 15 (not shown). The cell carburetter control is achieved by an electronic controller which operates selected cell carburetters or groups thereof to provide the required mixture flow for the engine conditions in response to sensors responding to engine load, acceleration, braking and air pressure, temperature etc as well as maintaining the carburetter at constant pressure. To achieve this different cell carburetters may have different  flow-rates and air/fuel ratios.
