Title: Method and apparatus for mass analysis by multi-pole mass filters
IPC: H01J49/42
Filed: 1971-04-19
Abstract: 1350980 Mass spectrometers VARIAN MAT GmbH 19 April 1971 [17 March 1970] 24227/71 Heading H1D In a mass analysis apparatus in which a beam of ions is passed through a mutipole mass filter, the range of ion masses transmitted through the filter is scanned by changing the values of the A.C. and D.C. field voltages applied to the poles of the filter whilst maintaining constant the value of a/q, where the function a = f(q) defines stable and unstable ion ton trajectories in the mutipole field and a and q areeach dependent upon the ion mass and are respectively dependent upon the D.C. component of the field voltage and upon the A.C. component of the field voltage. In the preferred embodiment, the D.C. component is zero and the filter transmits all ions having masses above a cut-off value determined by the value of q 0  at which the ion trajectory becomes unstable. Ion electron beam 6 produces an ion beam 9 in an ion source 1 containing a substance to be analyzed. The ion beam axially enters the quadrupole field 2 produced by four rods to which voltage source 14 supplies an adjustable D.C. voltage and/or an adjustable A.C. voltage. As the field voltage is raised, the point q o  of instability is reached for ions of progressively increasing mass so that the transmitted ion beam exhibits a step spectrum as ions are successively removed from the beam. To convert the step spectrum to a conventional line spectrum there is provided an energy analyzing system comprising an entrance electrode 15 and part-spherical mesh electrode 16 (both of which are earthed) and a retarding/collecting electrode 17 to which is applied a voltage adjustable so that only the most energetic ions, whose trajectories in the quadrupole field are associated with a value of q close to the parameter q 0  reach the collector. In alternative arrangements Figs. 8 and 9 (not shown) the energy analysis is effected by an electrostatic quadrant or a magnetic field.

Title: Process for preparing l-ª‡-aminolactam from a mixture of d-and l-ª‡-aminolactam
IPC: C07D223/12
Filed: 1960-07-12
Abstract: Racemic a -aminolactams are resolved by forming a precipitate containing only or primarily either D-or L-a -aminolactam as the salt of the optically active pyrrolidone carboxylic acid with the same steric configuration, such precipitation being effected in a liquid medium in which the salt of both D-and L-a -aminolactam with the said acid are insoluble or substantially insoluble, using the pyrrolidine carboxylic acid as such or as ammonium pyrrolidonate and in such smaller amount than that which is equivalent to the total amount of a -aminolactam that all or most of one of the optical antipodes of the said mixture remains in the liquid phase. The optically-active a -aminolactams are subsequently separated from their salts with the pyrrolidone carboxylic acid. The liquid medium used for the resolution is preferably dioxane or a hydrocarbon. Both the a -aminolactam and the pyrrolidone carboxylic acid may be added to the liquid medium of the process as solutions in a polar solvent, such as water or an alcohol, and this polar solvent is preferably expelled from the liquid medium at the same rate as it is added, e.g. by means of azeotropic distillation. When L-pyrrolidone carboxylic acid or its ammonium salt is used for resolution, the preferred amount is not more than 1 mole for mole of L-a -aminolactam.  The precipitate is then predominantly L, L-salt, and this may be taken up in a polar solvent and treated with an amount of L-a -aminolactam which is at least equivalent to the amount of D-a -aminolactam occurring as a L, D-salt contaminant in the L, L-salt.  The solution of L, L-salt in a polar solvent is then added to a further amount of the liquid medium used in the process, and pure L, L-salt is precipitated by expelling the polar solvent.  The L, L-salt may be passed as an aqueous solution over a cation exchanger in the ammonium form. L-pyrrolidone carboxylic acid passes through as the ammnoium salt and may be used again for the resolution step, while L-a -aminolactam may be recovered by subsequent elution with aqueous ammonia.  The original mother liquor containing mainly D-a -aminolactam may be racemized for re-use by heating it with sodium or anhydrous caustic soda.  When D-pyrrolidone carboxylic acid or its ammonium salt is used for resolution, the preferred amount is at least 1 mole per mole of D-a -aminolactam present. The precipitate is then predominantly D,D-salt, from which D-a -aminolactam may be recovered using an ion exchanger as before. The recovered D-a -aminolactam is then dissolved in fresh liquid medium and racemized for re-use by heating it with anhydrous caustic soda.  The original mother liquor containing mainly L-a -aminolactam may be subsequently evaporated to yield the required product.  The processes described above may be adapted for continuous working. Specified starting materials are racemic a -aminocaprolactam, a -aminovalerolactam and a -amino-oenantholactam. Specification 884,299 is referred to.

Title: Improvements in apparatus for manufacturing pottery ware
IPC: B28B5/02
Filed: 1938-08-22
Abstract: 508,154. Conveyers. MILLER, W. J. Aug. 22, 1938, No. 24708. Convention date, July 15. [Class 78 (i)] Apparatus for manufacturing jiggered and dried articles of pottery ware from plastic clay, comprises a fabricating machine, a dryer comprising a conveyer with mould supports, conveyers for empty and filled moulds respectively connecting said machine and dryer, and means synchronized with the machine and dryer for transferring simultaneously a plurality of filled and empty moulds from the filled mould conveyer to the dryer and from the dryer to the empty mould conveyer respectively. Figs. 1, 3 and 4 show. the application to a fabricating machine as described in Specification 471,589, [Group X]. The charged moulds are fed from the machine A by an endless conveyer 2 to a position adjacent an endless chain conveyer 151 extending in loops through a drying chamber. A number of these moulds are then transferred by a device 93 to a platform 4 on this conveyer and after traversing the drying. chamber are stripped of their ware at a point S. The empty moulds on reaching the point E are transferred by the device 93 to a conveyer 1 which returns them to the fabricating machine. At the same time, the device 93 transfers 'freshly charged moulds from the conveyer 2 to the dryer conveyer 151. The transfer 93 comprises opposed pairs of gripping bars 88, 89 and 90, 91 which are faced with resilient material and are suspended by members 126 from a frame 110 which is movable horizontally and vertically through levers 129, 121 operated by cams 130, 123. The bars 88, 90 and 89, 91 are supported adjacent each end from bars 94, 95 by channels 96, 97 respectively and are opened by links 100, 101 secured to the bars 91, 90 respectively and operated through levers by a cam 107. The cams 130, 123, 107 are mounted on a shaft 132 rotated through gears 133, 135 by a shaft 134 which is driven by a motor through a clutch having a remote control actuated by the leading mould of each group of moulds on the conveyer 2. The conveyers 1, 2 are intermittently driven through gearing from the shaft on which are secured the cams for controlling the movements of the fabricating machine. The conveyer 1 comprises three sectons which may be driven at varying relative speeds. Means is provided for discontinuing operation of the fabricating machine and the transfer device 93 in the event of the moulds on the conveyer 1 becoming deranged, and also for ceasing operation of the device which transfers the empty moulds from the conveyer 1 to the machine should the moulds not be seated properly in the device. Operation of the mechanism for feeding clay to the moulds is also prevented in the latter case. Specification 304,311, [Class 87 (i)], is referred to.
