Filed: 1963-03-26
Abstract: 964,644. Making aluminium powder. SWISS ALUMINIUM Ltd. March 26, 1963 [March 28, 1962], No. 11919/63. Heading B3A. A process for the production of aluminium powder having a high bulk weight suitable for making sintered aluminium bodies and containing between 4 and 15% of oxide comprises wet grinding the aluminium in a solvent in the presence of a gas which contains for a substantial part of the duration of the process some but less than 20% free oxygen by volume available for the oxidation of the aluminium. The oxygen content may be reduced by throttling the air supply during grinding. Aluminium may be ground in white spirit in a ball mill 1 with the hollow shafts 2 closed so that oxygen in the air is used up by oxidation of aluminium particles and the charging opening 6 opened for five minutes every six hours to enable fresh air to enter. Again, aluminium may be ground in a vibrating mill for five hours with a full air supply and then for eleven hours with the air cut-off so that the oxygen content falls below 20%. A substance soluble in the solvent and readily oxidizable may be added to use up oxygen. Solvents having a low solubility for oxygen may be used. Grinding aluminium in white spirit in a ball mill 1 with air drawn continuously through hollow shafts 2 by a fan 5 is acknowledged. Specification 698,789 and German Specification 1,101,917 are referred to.

Title: Logic level translators
IPC: H03K19/018
Filed: 1976-03-25
Abstract: 1518455 Transistor logic circuits HONEYWELL INFORMATION SYSTEMS Inc 25 March 1976 [26 March 1975] 12055/76 Heading H3T A logic level translating circuit comprises: an emitter coupled logic stage 1 fed with signals at the first logic level, energized from a logic level power supply and having an output transistor Q2; a TTL circuit 3 fed from the collector of Q2 and energized from a second logic level power supply; and a clamp circuit 4 connected to the collector of the transistor Q2 to limit current flow through that transistor. If a logical "I" at -0À5v is applied to V IN , Q1 is cut off, the Q2 conducts providing a current path from the + 5v supply line through R4, Q2 to the -3À3v supply line. Circuit 4 clamps point V2 to 0À3v so that transistor Q3 is off, thus turning off transistor Q6. The voltage at V3 turns on Q4 completing a current path from the + 5v line through R7, SD3, Q4, R9 to TTL earth to turn on Q5 and produce a TTL logic "1" level of 3À5v at V OUT . Since the lower value of V2 is limited to 0À3v, negative fluctuations at the collector of Q2 do not saturate the transistor, and parasitic emitter-base capacitances are reduced. If the input is a logical "O" at 0v, Q1 turns on and Q2 turns off turning on Q3 and turning off Q4. When the base of Q3 rises to 1À6v, the base of Q6 reaches 0À8v and Q6 turns on to give a TTL "O" output of 0À4v at V OUT . Q1 provides current to reduce the base potential of Q5 so that it turns off before Q6 turns on, thus reducing surge current.

A winch f at the front of the frame ais then operated to pull the truck on to the fixed track irons k, by means of a cable u connected to the winch and passing round the pulley t, until the wheels n abut chocks k<2> formed by upwardly-inclined portions of the tracks k when one limb of a spring-controlled hairpin bolt q, Fig. 4, is inserted in holes p<1> in a bracket p on each chock in the path of a wheel-spoke, to prevent backward movement of the truck. The cross-head s is also clamped in position by a nut x and plate w. Finally the rear portions k<1> of the tracks are folded upwardly so that they lie against the tyres of the truck wheels n and are secured by chains o. The sides of the frame a are supported by springs upon deeplydropped portions of an upwardly-bowed axle, and to prevent axle oscillations the frame a is fitted with guide-lugs for engaging one in front of and one behind each of the downwardlyextending axle-portions j<1>. The coupling c includes a spring-controlled draw-bar b which is pressed rearwardly against a brake-operating lever d when the tractor decelerates. Instead of two pairs of irons g, a single pair may be provided forming a slideway for a truck handle and may be fitted with a pair of fixed hooks for engaging the handle. The hairpin bolt q may be replaced by other means for locking the truck wheels.

Title: The manufacture of therapeutically useful bis-quinolyloxy-alkane compounds
Filed: 1947-05-06
Abstract: Quaternary salts are formed of bis-quinolyloxyalkanes, which are prepared by condensing a dihalogenoalkane, in which the chain between the halogen atoms is straight or branched and contains at least two carbon atoms, with a hydroxyquinoline in an alkaline medium.  It is preferred to use a 6- or 8-hydroxyquinoline, and a halogenoalkane of the formula X.(R1CR2).X, where n is not less than 3 and not more than 7, R1 and R2 are hydrogen or lower alkyl, and X is halogen, preferably bromine. The condensation is preferably performed in an aqueous-alcoholic solution of a strong alkali, and the formation of the quaternary salts via the hydrochloride, by treatment with an alkyl salt RX, where X is halogen or an acid residue, such as sulphate and R is a lower alkyl group, e.g. methyl to butyl, allyl, or hexyl.  The quinoline nucleus may be substituted.  In the examples: (1) 8-hydroxyquinoline is heated with 1 : 3-dibromopropane in aqueous-ethanolic sodium hydroxide to give, after acidification, the dichloride of 81 : 811-diquinolyloxy-1 : 3-propane.  The dimethiodide, diethiodide, di-n-proprodide, di-isopropiodide, and dibutiodide are then prepared from the free base; (2) by a similar procedure using 1 : 4-dibromobutane there are prepared the following quaternary salts of 81 : 811-diquinolyl-1 : 4-butane: di-isopropiodide, dimethiodide, diethiodide, di-n-propiodide, and dibudiodide.  Similar series of compounds are obtained on replacing 1 : 4-dibromobutane with pentane, hexane, and heptane derivatives, and/or the 8-hydroxyquinoline with the 6-isomer; (3) the diethiodide of 61 : 611-diquinolyloxy-1 : 4-pentane is prepared from the product of 6-hydroxyquinoline and 1 : 4-dibromopentane; (4) the diethiodide of 81 : 811-diquinolyloxy-1 : 4-pentane is prepared from the product of 8-hydroxyquinoline and 1 : 4-dibromopentane condensed in the presence of sodium ethoxide.
