Abstract: Nitro - compounds of saturated aliphatic hydrocarbons are prepared by reacting aliphatic mono-olefines containing from 3 to 6 carbon atoms with nitrogen trioxide, or nitric oxide, and oxygen or an oxygen-containing gas such as air in the presence of a solvent as hereinafter defined, but excluding the process in which prior to contact with the olefine, the nitrogen oxide and oxygen or oxygen-containing gas are reacted together and in which the nitrogen oxide content of the reacted mixture is present as nitrogen tetroxide.  The solvents comprise those defined in Specification 580,260, namely, saturated aliphatic, alicyclic-aliphatic or alicyclic compounds containing carbon, hydrogen and oxygen only and having no oxygen-containing groups except ether or ester groups and no 3-or 4-membered rings, but excluding formic acid esters; saturated heterocyclic or aliphatic-heterocyclic compounds containing carbon, hydrogen and oxygen only and having only carbon and oxygen in the ring and no other groups except hydrogen, hydrocarbon, ether or ester groups, but excluding such compounds containing 3- or 4-membered rings. Nitration may be effected preferably at atmospheric temperature and pressure using solutions of the reactants in the specified solvents or the nitrogen oxide and oxygen may be passed continuously through a solution of the olefine.  With gaseous olefines, the olefines and oxygen are preferably passed through a solution of the nitrogen oxide.  Normally, anhydrous conditions are employed.  The oxygen may be introduced at any stage in the process. The olefines may be used pure, as mixtures or with diluents.  The products comprise dinitro compounds, nitro/nitrates and nitrites.  To facilitate working up, the crude mixture is treated with water or an aliphatic alcohol having less than 6 carbon atoms whereby nitrites present are decomposed to nitro-alcohols.  A number of methods of separating the various products are described.  Compounds which may be prepared are 1 : 2-dinitropropane, 1-nitropropanol-2 and its nitrate from propylene and 1 : 2-dinitroisobutane, nitro-t-butanol and its nitrate from isobutene.  Specification 583,468 also is referred to.  According to the Provisional Specification the mono-olefines may contain substituent groups which may be aromatic.

Abstract: 258,548. Rieck, W. O. P., (trading as Rieck vorm. Crown Cork Co., Ltd., W. O. P.). Sept. 19, 1925, [Convention date]. ' Crown-corks,' applying.-Relates to crowncork stoppering machines of the type in which differences in the level of the bottles are compensated for hydraulically by means of a displacer piston movable axially in relation to the bottles. The Figure shows a section through a machine having a number of bottling heads arranged to rotate around a vertical axis 2. According to the invention the overflow port 8 for the displaced liquid is closed by a cam operated valve 9 which allows overflow until shortly before the stoppering operation. The valve 9 is operated by a cam 16 and co-operating roller 15 while the descent of the stoppering head 1 is controlled by the cam 11 and roller 10. The displacer piston 6 mounted in the cylinder 3 has a second overflow port 7 which is normally kept closed by the spring-pressed valve 17 and is only opened by excessive pressure during the stoppering operation. The valve 9 is opened against the action of a spring 14 by the cam 16. For manual adjustment a by-pass 20 is provided which is controlled by a set screw 21 which establishes communication between the liquid space in the cylinder 3 and the interior of the piston 6. The invention may be applied to a machine having only one stoppering head controlled by a vertically disposed cam.

Title: Control device for an energy supply system
IPC: F02D41/00
Filed: 1972-03-21
Abstract: 1325975 Transistor switching circuits for electromagnetic actuators BENDIX CORP 21 March 1972 [1 April 1971] 13180/72 Heading H3T [Also in Division G1] In an I.C. engine the level of voltage applied to, and hence the level of current flowing through the fuel injection valve coils is controlled in dependence upon both the level of energizing voltage applied to and the current flowing through the coils. In this manner the coils are initially energized with a high voltage which is subsequently reduced so that the valves are speedily opened and then supplied with current just sufficient to maintain them open. The fuel injection system, Figs. 1 and 2 (not shown) is of the type which provides a pair of variable duration injection pulses upon being triggered in response to engine rotation. Each pulse pair is applied at location 126 to energize the injector valve coils 606 via a power stage 302. A pair of variable impedances 304, 306, e.g. transistors, are provided to control the level of energizing voltage applied to the coils. When the coils are initially energized, the voltage at location 316 is regulated to a high value V 2  by comparing it at 312 with the voltage V 2  to regulate impedance 306. As more current flows through the coils, the voltage at location 314, indicative of the current flow, increases until, when it reaches the value V r  set by a generator 318, is maintained at that value by varying impedance 304. The voltage at 316 then begins to drop thereby causing the reference voltage V r  to drop to a second value. The comparator 310 then varies the impedance 304 in order to reduce the voltage at 314 to the new reference V r  thereby providing a reduced current flow through the coils. Details of the transistorized circuits 302, 304, 306, 310, 312, 318 and 322 are provided in Fig. 4 (not shown).

Filed: 1925-05-25
Abstract: 244,647. Gear Grinding Co., Ltd., and Snarry, J. W. May 25, 1925. Indexing. - A dividing-mechanism for gear-grinding or other machines comprises a dividing- wheel a mounted on the workspindle b, the teeth c of the wheel each having a radial face d and the angular positions being determined by a positioning-pawl e whose engagement with the teeth is limited by means of an adjustable stop g coacting with a lug f on the pawl. The stop is located so that when the pawl is engaged the operative end face of the pawl is radial to the dividing wheel. The positioning-pawl is intermittently disengaged against the pressure of a plunger h by means of a cam i on an oscillating member j which also carries an actuating-pawl k which moves the wheel through the required angle while the positioning-pawl is disengaged. A locking-pawl t may be employed to prevent backward movement of the dividing-wheel during the idle stroke of the actuating-pawl. The arm j is oscillated by a, fork on a slide n carrying a rod r which is reciprocated from a crank q through an adjustable spring s. At the end of each operative movement the spring is compressed and thus causes the actuating-pawl to press the indexing- wheel firmly against the positioning-pawl.

Abstract: 703,653. Welding by pressure. STANDARD TELEPHONES & CABLES, Ltd. June 8, 1951, No. 13654/51. Addition to 673,890. Class 83 (4) In an electric pressure welding machine comprising fixed and movable electrodes wherein the movable electrode is mounted in a head connected by a plurality of spring strips to a fixed support so that the movable electrode travels in a direction substantially parallel to the support axis as claimed in the parent Specification, the nose 18 of an operating arm 12 engages a backwardly extending platform 19 on the head 7 to normally constrain the electrode 8 from the fixed electrode 3 and to maintain the spring strips 10, 10a, 11 in tension and a compression spring 15 is located between a forward extension 17 on the arm 12 and the head 7. When the arm 12 commences to move, the strips 10, 10a, 11 urge the electrode 8 towards the electrode 3 until the springs 10, 10a, 11 are no longer in tension. Upon further movement of arm 12 the extension 17 of the arm 12 acts through the spring 15 to move the electrode 8 and simultaneously tension the strips 10, 10a, 11 in the sense opposite to their normal tension. Movement of the arm 12, which is pivoted at 13 to the support 1, is effected by rotation of the lever 24, by operation of e.g. a foot pedal, and causes lowering of the electrode 8 until it engages the work. Further movement of the arm 12 causes compression of the spring 15, the nose leaves the plate 19 and the plate 19 moves relatively to a plunger 21 until the plunger 21 is moved upwardly to operate a switch 20 to commence the welding current supply. Current is supplied to the electrode 8 through the strips 10, 10a, 11. After welding a spring 23 returns the electrode 8 and arm 12 to their normal positions. A nut, the position of which is adjustable by turning a screw 16, is arranged to engage the spring 15 and by this means the welding pressure is adjusted.

Abstract: 1535953 Processing black liquor JOHN ZINK CO 5 April 1976 [21 July 1975] 13683/76 Heading F4B [Also in Division D2]  In a method of processing black liquor to recover chemicals in the pulping process, the liquor is fed by the conduit 10 into a combustion chamber 16 and air is supplied at 20 so that the liquor is burned under less than stoichiometric conditions whereby a large amount of combustibles are created. The gases pass into the quench tank 24 via the section 22 where water and/or green liquor is sprayed into the gases from the conduit 26 to remove particulate matter and thus produce green liquor in the quench tank. Resulting gases and any remaining particles pass through a venturi scrubber 36 where green liquor is injected through the conduit 34 and gases then pass to a vapour liquid separator 28 where further green liquor is separated. Part of the green liquor produced in the quench tank 24 and separator 28 is used to spray in through the conduits 26 and 34 and the remainder may be pumped by the conduit 38 for use elsewhere. Make up water may be introduced into the conduit 26 via conduit 32. Black liquor fed to the combustion chamber 16 by the conduit 10 may be divided so that part flows through the conduit 12 to the burner 14 while the remainder is sprayed into the combustion chamber by way of conduit 18. The residual gases from the separator 28 pass via a conduit 42 for further utilization that may include burning in a combustion zone 56 for heating a boiler 58 with gases finally exhausting via a stack 46.
