A bleed manifold 62 is associated with the outer wall of the snout member 26 being controlled by valve 66. In normal operation the air-flow through the passage 32 is deflected downwardly and does not flow directly into the inlet 36, but when the fuel/air mixture is to be weakened so as to prevent formation of smoke, the bleed valve 66 is opened whereby the air-flow through the passage 32 is deflected upwardly as in Fig. 2 so that some air flows directly into the air inlet 36 with a dynamic head due to its velocity. In a second embodiment the air-flow through inlet passage 32' is controlled by blowing air under pressure from manifold 70 through an opening 72. In normal operation the air-flow through passage 32' is deflected downwardly, Fig. 3 (not shown) and does not enter directly the air inlet 36 . When air is blown through opening 72 the airflow is deflected as in Fig. 4 so that some air enters the air inlet directly with dynamic head due to its velocity so preventing the formation of smoke. In a further embodiment the combustion equipment comprises a normal fuel sprayer, the air-flow being controlled by bled or blown air means.
Patent GB-653379-A (GB)
Title: Process for refining penicillin x
IPC: C07D499/18
Filed: 1946-09-13
Abstract: Penicillin X is purified in the form of its potassium salt by preparing a solution of potassium penicillins (including X) in a secondary aliphatic monohydric alcohol having 3-6 carbon atoms in the molecule, the solution being saturated or supersaturated with respect to potassium penicillin X; the saturated solution is then cooled or allowed to evaporate and crystalline potassium penicillin X separates on standing; if the solution is supersaturated, the salt crystallizes on merely allowing to stand. Penicillin G may or may not be present, and in the former case, the solution is below the concentration of potassium penicillin G necessary to saturate it.  Thus, penicillin G should be present only in a minor proportion, or should be removed by a preliminary extraction with chloroform.  The process and the preliminary purification steps are carried out in the same manner as for ammonium penicillin X in Specification 653,377 with the exception that step 3 (A) is not applicable.  For neutralization, potassium hydroxide, carbonate and bicarbonate are suitable, phosphates leading to contamination of the product.  In the examples, potassium penicillin X is crystallized from (1) sec.-butyl alcohol, after purification via steps 1 and 3 (C); (2) isopropanol after step 3 (B); and (3) a mixture of sec.-butyl alcohol and isopropanol after step 3 (C).  Other alcohols mentioned as suitable are 2 - pentanol, 3 - pentanol, 3-methyl-2-butanol and 2-hexanol.  Specifications 642,369, 642,370, 642,371 and 642,372 also are referred to.  According to the Specification as open to inspection under Sect. 91, the process is applicable to starting materials containing comparatively large proportions of penicillin G.  The product does not then consist of pure potassium penicillin X, but the latter has been freed at least in part from non-penicillin organic and inorganic impurities and from penicillins F and K.  This subject-matter does not appear in the Specification as accepted.

Abstract: 285,136. Reyrolle & Co., Ltd., A., Leeson, B. H., and Mirrey, J. Nov. 10, 1926. No Patent granted (Sealing fee not paid). Oil - switches; arcrupturing devices; magnetic blow-outs. - Oil switches of the kind using two or more sets of contacts connected in series, have each set of contacts disposed in a compartment. in a preferably cylindrical tank, the compartments being separated by radially arranged insulating barriers, and the circuits are so arranged that the arcs formed are magnetically blown out in a radial direction. Fig. 1 shows one form diagrammatically, a cylindrical oil-tank being divided into six sector-shaped compartments by vertical insulating barriers D' &c., radially arranged so that oil can circulate round their edges. Each compartment contains an upper (fixed) and lower (movable) contact A<1>, B<1> &c., the contacts being in series and connected so that the current flows in opposite directions in adjacent pairs, thus causing a magnetic blow out action of each arc in a radial outward direction. As the arc moves outwards it encounters an increasing width of oil which facilitates expansion of gas bubbles formed as the arc is drawn out. In this Figure, the current path between the leads E, E<1> crosses the tank via the connector G<1> but in another form (Fig. 3, not shown) the path is arranged to follow the tank wall circumferentially. Figs. 5 and 6 show in greater detail a form similar to that of Fig. 1, wherein the lead-in bushings O, O<1> carry fixed contacts P<1>, P<4> and two insulators O<2>, O<3> carry bridging members Q, Q' respectively connecting contacts P<2>, P<3> and P<5>, p<6>.
