Title: Novel heterocyclic compounds and a process for the manufacture and conversion thereof
Inventor: OSBOND JOHN MERVYN
Filed: 1957-08-06
Abstract: The invention comprises quinolizine compounds of the formula <FORM:0861524/IV (b)/1> where R is alkyl or aralkyl, Xnis an anion of valency n and S stands for 10-methoxy-, 9,10-dimethoxy-, 9,10-methylenedioxy- or 8, 9, 10-trimethoxy-.  Preferably Xnis the iodide ion.  These compounds are named 3[8,9],10-substituted - 2 - hydroxy - 3,4,6,7 - tetrahydrobenzo[a]quinolizinium salts.  They may be prepared by cyclising the appropriate 1-[b -[41(,2131)-substituted - phenyl] - ethyl] - 2 - oxo - 4-ethylenedioxy - 5 - (alkyl or aralkyl) - piperidine in a Bischler-Napieralski reaction (e.g. by heating at 100 DEG C. in anhydrous toluene for a few hours with POCl3), hydrolysing the resulting 2 - ethylenedioxy - 3 - (alkyl or aralkyl)-[8,9]10 - substituted - 1,2,3,4,6,7 - hexahydrobenzo[a]quinolizinium chloride with a dilute mineral acid, and, if desired, exchanging the cation of the resulting salt for another cation.  The compounds of the invention may be converted into a 3-(alkyl or aralkyl)-2-hydroxy-[8,9]10 - substituted - 1,2,3,4,6,7 - hexahydrobenzo[a]quinolizine either by reduction with an alkali metal boron hydride to produce a 3-(alkyl or aralkyl) - 2 - oxo - [8,9]10 - substituted-1,2,3,4,6,7 - hexahydrobenzo[a]quinolizine followed by catalytic hydrogenation, or by treatment with an alkali to produce a 3-(alkyl or aralkyl) - 2 - hydroxy - [8,9]10 - substituted-6,7 - dihydro - 4H-benzo[a]quinolizine and then either catalytically hydrogenating the latter (or a salt thereof) or reducing it with LiAlH4 and catalytically hydrogenating the resulting 3-(alkyl or aralkyl)-2-oxo-[8,9,]10-substituted-1,2,4,6,7 - hexahydro - benzo[a]quinolizine.  Hydrohalic acid salts of the various bases are described.  Specifications 789,789, 800,969 and and 861,525 are referred to.

Title: Improvements in and relating to electric control systems employing thermionic valves or the like
IPC: G05B11/01
Filed: 1931-09-03
Abstract: 366,431. Displaying. BRITISHTHOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Whitney, C. F. ; 11, North Ten Broeck Street, Scotia, New York, U.S.A.) Sept. 3, 1931, No. 24780. Convention date, Sept. 4, 1930. [Class 3 (i).] A thermionic or like electric valve is used to control a lighting circuit or a window display device upon the approach of an observer or other conducting body. The valve 16 has its cathode 13 energized by a secondary coil 18 of a supply transformer 12. The cathode is connected to an intermediate point of the other secondary coil 17 one end of which is connected to the valve anode 14 through the load resistance 11. The load may comprise the apparatus to be controlled, or a relay for controlling that apparatus indirectly. The valve grid is connected between two condensers 19, 20 which form a bridge across the secondary coil 17. A grid leak may shunt the condenser 19. Normally the grid is negatively polarized and the valve passes no current. When an observer, however, approaches an exposed plate 22, the resulting capacity to earth is connected in parallel to the condenser 20, the ratio of the bridge 19, 20 is altered, and the grid voltage becomes more positive. The valve then passes current and the load 11 is energized. When the observer recedes the load is de-energized.

Title: Improvements in or relating to rotary internal combustion engines
IPC: F01C1/44
Filed: 1964-06-16
Abstract: 1,109,401. Rotary internal combustion engines. T. DOHERTY. Sept.14, 1965 [June 16, 1964], No. 24832/64. Heading F1F. A rotary I. C. engine comprising a casing 1, Fig. 1, defining a cylindrical chamber eccentrically mounting a rotor 2 having a plurality of vanes 3 hingedly connected thereto and bearing at their free edges against the chamber wall includes an ignition device 18 comprising twin spark-plugs in combustion chambers externally of the casing which are connected to the chamber by separate pipes tangential to the chamber. Explosive mixture introduced into the chamber through a carburetter 13, an induction manifold 14 and an inlet port 16 is ignited by the sparkplugs which are alternately fired so that adjacent vane spaces are associated with different plugs. The combusted gases are exhausted through a port 17. The ports 16, 17 are spaced so that each vane space is momentarily open to suction and exhaust, with the exhaust gases leaving the space creating a vacuum to assist the introduction of the explosive mixture. Each vane is fitted with a stop 4a to ensure that the trailing vane of the space in which combustion is effected, physically contacts the chamber wall. Flexible steel strips 25 extending the full length of the rotor provide gas seals over the hinges 4 and spring- loaded discs (not shown) between the rotor end faces and the casing covers provide end seals for the chamber. An air inlet in one casing cover and an air outlet in the other casing cover cooperate with axially-extending rotor passages 45. . 51 to cool the motor.

Title: Treatment of molten metals and alloys
Inventor: ANDREW ALFRED TRESHAM
IPC: B22D21/00
Filed: 1958-08-01
Abstract: Modifying or conditioning additives for molten light metals and alloys are formed into blocks which either remain coherent in the molten metal or consist wholly of material which is converted to gas in the molten metal, each block having an aperture through which is securely fastened a sinker of high specific gravity such that the specific gravity of the sinker and additive is greater than that of the molten metal.  The sinker may consist of a bolt with a locking nut, or may consist of a curved bar, with or without a stop at one end, the curvature being such that the sinker is retained in place by the pressure of the molten metal. The sinker may be made of cast iron, alloy iron or steel coated with refractory, refractory enamel or graphite, or may be made of tungsten carbide or bonded zircon sand.  The block preferably contains, in addition to the active ingredient, a substance which will sinter at the temperature of the molten metal to prevent the block from breaking up.  Substances mentioned are common salt, fluorspar, magnesia, or crushed firebrick, optionally with a binding agent, e.g. a silicate.  Specification 827,619 is referred to.

Title: Cathode ray tubes herbicide
IPC: H01J29/50
Filed: 1974-06-05
Abstract: 1461796 Cathode-ray tube SONY CORP 5 June 1974 [11 June 1973] 24967/74 Heading H1D In a three-in-line beam cathode-ray tube 3 (seen from above in Fig. 4) with common gun 4 and grids G1-G5, magnetic deflection yoke 5 and convergence plates c, the spot on full lateral deflection becomes elongated radially. Electrostatic compensation by distortion of shape of one or more grids G1-G5 corrects peripheral spot shape but vertically elongates spots on the vertical centre line. A magnetic quadrupole device 6 further corrects the spot shape to uniform circularity without high power dissipation. If converging lens grid G4, normally a circular ring, is elongated vertically (Fig. 5A, not shown) and the beams are under-focused at the screen (i.e. converging beyond screen), or if G4 is elongated horizontally with over-focused beams (Fig. 5B, not shown), the peripheral horizontal elongation can be corrected. Similar deformation may be applied to G3 or G5 but in the opposite sense since these form diverging lenses. Alternatively either G3 or G5 may be a circular closed cup with under-focused beams passing through a common horizontal slot (Fig. 6A, not shown), or with over-focused beams passing through separate vertically oriented slots (Fig. 6B, not shown). Grids G1 or G2 may also be used for correction. The magnetic device 6 (Fig. 8, not shown) comprises one or more ferromagnetic rings each with toroidal windings energizing four polepieces alternately N and S, radially inward at 45 degrees to the vertical, the winding being fed with parabolically varying current in step with the lateral deflection current.

Title: Accessory-attachment device for a tractor
IPC: B60D1/46
Filed: 1973-05-25
Abstract: 1426210 Tractor power lift KLOCKNERHUMBOLDT-DEUTZ AG 25 May 1973 [27 May 1972] 25038/73 Heading A1P A tractor accessory attachment device for draught and position control which includes two parallel tractor-accessory coupling links which are raised or lowered by respective hydraulic jacks mounted on the tractor also includes, (a) a first mechanism whereby the jacks are operated should the links' level differ from a pre-set value, and (b) a second, synchronising mechanism whereby any differential movement of the links is corrected. The first mechanism Fig. 2 includes a torsion bar (not shown) which couples the ends of the links nearer the tractor and which transmits link movement via bar 14 to a comparison lever 15. This lever is connected to a linkage 19 itself connected to an external lever which pre-sets the desired link level. The comparison lever 15 transmits link movement to a rocking lever 16 and slide bar 17 which operates jack fluid pressure control valve 41, Fig. 4.  The synchronising mechanism, Fig. 3, includes a slide bar 20 pivoted to comparison lever 26 itself pivoted to levers 22, 23 by bars 24, 25. A pair of shafts 9 receive movement from the links via parallel linkages 8, 7 and the mechanism transmits differential link movement to synchronising slide valve 37, 38 Fig. 4. Fluid is pumped from reservoir 30, Fig. 4, to jacks 4, 4' by pump 29 under the control of the valves 41, 37, 38 and valves 32, 53. Non-synchronised movement of the links causes the valve 37, 38 to move to cut off or bleed fluid from one of the jacks. Movement of control valve 41 to the right prevents pressure escape to the reservoir 30 via line 39. The resultant pressure build-up behind throttle 40 moves valve 32 to the left to allow fluid to raise the jacks. Movement of valve 41 to the left causes pressure build-up behind throttle 45 and moves valve 53 to the left. This allows fluid escape from the jacks and they lower the links.

Abstract: 1400556 Continuous casting RHEINSTAHL HUETTENWERKE AG 26 May 1972 [28 May 1971] 25099/72 Heading B3F [Also in Divisions F4 and C7] A purging gas, e.g. for entraining oxide particles with bubbles 13, is fed into molten metal (such as steel) teeming from a vessel (such as a tundish 9) before it leaves a nozzle 5 to enter a pouring spout 15 extending into metal below a slag layer 19 in a continuous casting mould 17. Gas such as Ar or another noble gas or mixture of gases is supplied at 3-18 litres/minute giving a volume between one-fortieth and one-tenth the volume of steel teemed. Oxide impurities are carried up and deposited in the slag layer 19. The gas may be supplied by way of a needle valve controlled with reference to the position of a stopper 4 which controls the melt flow, and enter through a connection 6 and a duct 2 through the stopper and its rod 1. Alternatively, a sliding gate nozzle may be used to close the tundish and a lance extended into the vessel to pass the gas (and possibly alloying elements and deoxidizing agents) into the metal leaving the vessel. In the form shown, the elements and agents, such as Al and Ti, are passed through the duct 2 in the form of a wire 14, possibly fed from a roll 7 by an electric motor controlled by reference to the position of the stopper 4. The wire feed may be at a constant or a controlled rate proportional to the pouring rate or increasing as casting continues. The exit 3 from the duct 2 has a diameter between 0À5 and 3 mm. If wire 14 is passed through the duct 2, the free cross-section of the exit 3 for the gas should be 0À2-7 sq. mm.

Abstract: 278,881. Courtaulds, Ltd., and Topham, C. F. Oct. 11, 1926. Apparatus for making filaments.- When dry spinning artificial silk &c., filament-formation at the spinning dies is started by applying to the solution a sudden considerable increase of pressure in excess of the pressure exerted by the pump or other means which normally supplies the solution to the dies. Conveniently the sudden increase in pressure is obtained by the aid of an auxiliary pump connected at a point intermediate between the spinning pump and the die, and comprising a plunger moving in a barrel or a flexible diaphragm; a tap may be interposed in the connection to the auxiliary pump in order that the latter may be put out of action while normal spinning is taking place, or other means for securing the plunger or diaphragm in a fixed position, may be adopted. The auxiliary pump may be so constructed that the plunger H fits the barrel of the pump from end to end; in such a case and in order to obviate the formation of a film of solid cellulose acetate in the barrel, there may be formed at an intermediate point of the latter, an annular space L, which space is filled with acetone or other solvent, introduced and removed through openings closed by screws N.

Abstract: 1,000,977. Detecting flaws and corrosion. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. July 2, 1962 [July 3,1961], No. 25291/62. Heading G1N. In an arrangement for the detection of flaws corrosion &c. in a ferrous tubular member such as an oil pipe line, energizing and pick-up coils 10,11 Fig. 3, energized by A.C. from a source housed in the sonde, are coupled to a recorder which may be in the sonde, and the defects recorded are located in respect of marks on the chart provided by the response of the probe to the presence of welded joints. The phase displacements of the currents in the two coils, are recorded photographically on a chart 22, Fig. 1, by a neon light 19 having a shield, 24 the edge of which is a helix, and a slotted screen 21 interposed between the lamp and the film, the neon lamp and shield being rotated in synchronism with the A.C. supply to the energizing coil 11 and the lamp being made to flash as the signal current from the pick-up coil passes through zero. The sonde is driven by the flow of the fluid by rubber pistons 37-42 and its speed is maintained constant by a servo system which controls a valve 46 in a by-pass tube in accordance with a speed signal developed by a roller 47 engaging the side of the tube. Speed control may alternatively be effected by the difference in pressure between the fluid in front of and behind the sonde. The coils are resiliently mounted so that they may be displaced laterally in order to avoid being damaged by projections from the side of the tube and are located in different sections of the sonde which are coupled together through universal joints. The alternating current is developed from a battery supply by a multivibrator 54, 54<SP>1</SP>, Fig. 4, which is triggered by the 120 cycle output from a unijunction transistor diode 50 oscillator circuit to produce a 60 cycle square wave output the amplitude of which is controlled by a Zener diode circuit 62. The output is applied to exciter coil 10, a film drive motor 23 and a synchronous motor 20 for rotation of the neon lamp, through push-pull transistors 59, 60. The pick-up coil signal is fed to a tuned transistor amplifier 65 Fig. 5, via a transistor amplifier 64 the former including parallel negative feedback paths 68, 69 connected to earth by an adjustable resistor 70 whereby the frequency response of the stages may be adjusted to 60Cs/5. A trigger circuit 16 controlling the firing of neon tube 18 comprises a trigger pair of transistors 75, 76, the former of which is rendered conductive when the signal exceeds a level preset by resistor 74. A short response switching transistor 79 is fired by a narrow width differentiated pulse from the output of transformer 77 to fire the neon tube. Specification 886, 760 is referred to.
