Abstract: The present invention provides a nanospray means and method for use in mass analysis instruments. Specifically, a nanospray assembly is composed in part of a base, union, retainer, and nanospray needle, and an entrance cap, first capillary section, and union. Adjustments to the position of the nanospray needle within this assembly are made independent of the remainder of the ion source. The nanospray assembly is integrated with the remainder of the source by joining the first capillary section (of the nanospray assembly) with a second capillary section which is fixed in the body of the source.

Abstract: An elastic motor having a constant torque characteristic utilizes a reel with elastic divided into unit lengths that are stretched to their maximum tension. Each unit length of the elastic is allowed to relax to its normal state while generating work in a process that will continue until the wheel is fully unwound. The present invention will ease design of mobile devices and the like by providing a power source having a predictable, constant, and stable output characteristic.

Abstract: A means and method are disclosed whereby ions from an ion source can be selected and transferred to a time-of-flight mass analyzer via an arrangement of multipoles in such a way that fragmented ions may be generated by collision-induced dissociation or surface-induced dissociation. First, ions from the source are collisionally cooled by a first multipole. Second, the m/z range of the ions is then selected by a second multipole (preferably a quadrupole). Third, the selected ions are allowed to collide with a “collision surface” capable of producing fragment ions. Fourth, these fragment ions are collisionally cooled in a third multipole and delivered into a TOF mass analyzer for subsequent analysis of the fragmented ions.

The system of the present invention has the ability of achieving greater pressure drops than systems previously disclosed. Furthermore, it is easily fashioned into a flexible unit that can adapt to traversing curved surfaces.

Abstract: Disclosed is an improved vacuum cleaning apparatus utilizing a self-sustained vortex flow in a centrifugal separator. More specifically, vortex flow is maintained via pressure differentials allowing the ejection of dust and other particles without bags, filters, or liquid baths. Furthermore, the impeller inside of the separator serves the dual purpose of moving air through the system as well as creating a cylindrical vortex fluid flow providing an efficient and simple configuration. Also disclosed herein is a complete toroidal vortex vacuum cleaner in which a toroidal vortex nozzle is used in conjunction with the centrifugal separator. The vacuum cleaner exhibits recirculating airflow that not only prevents unseparated dust from escaping into the atmosphere, but also conserves the kinetic energy of the flowing air. The present invention excels in producing clean air of a better quality more efficiently, more quietly, and more simply than the prior art.

Included in the debris collection apparatus is a compaction means that captures debris caught in the toroidal vortex flow, and deposits it in a desired chamber.

Abstract: Disclosed are improved vacuum cleaning apparatus that utilize toroidal vortex air flow in order to establish a pressure differential capable of attracting debris. These systems differ significantly from prior vacuum cleaners in that they are essentially closed systems; there is no constant intake and exhaust of fluid. Disclosed herein are toroidal vortex vacuum cleaner nozzles that function with a fluid delivery system, which, in combination, yield a toroidal vortex that is split between the extreme ends of the nozzle. Also disclosed is a complete toroidal vortex vacuum system employing a centrifugal dirt separator. The present invention excels in being more efficient, lighter weight and quieter than the prior art.

Abstract: A method and apparatus for analyzing ions by determining times of flight include using a deflector to direct ions away from their otherwise intended or parallel course. Deflectors are used as gates, so that particular ions may be selected for deflection, while others are allowed to continue along their parallel or otherwise straight path, from the ion source, through a flight tube, and eventually, to a detector. According to the present invention, an extended Bradbury-Nielson gate, in the form of a series of plates, with equal but alternating opposite polarity potentials, is used as an ion deflector or gate.

Abstract: A means and method are disclosed for multiplexing a plurality of samples from multiple sprayer devices to be efficiently transferred to a mass analyzer for subsequent analysis. Sample sprays are formed from a plurality of sprayers, which are desolvated to form the sample ions. The sample ions are then selected from one of the sprayers for transportation into a mass analyzer. To accomplish this, the apparatus of the invention comprises a multi-part capillary wherein a first section thereof is connected to a motor which is able to move this first section from one sprayer to the next. This first section may be a flexible tube-like structure loosely mounted in an aperture of a cone-shaped end of a motor which rotates such that the sampling orifice may be aligned with different sprayers at different times to sequentially and repetitively sample ions produced by each of the plurality of sprayers.

Abstract: The present invention is an improved apparatus and method for mass spectrometry using a dual ion trapping system. In a preferred embodiment of the present invention, three “linear” multipoles are combined to create a dual linear ion trap system for trapping, analyzing, fragmenting and transmitting parent and fragment ions to a mass analyzer—preferably a TOF mass analyzer. The dual ion trap according to the present invention includes two linear ion traps, one positioned before an analytic quadrupole and one after the analytic multipole. Both linear ion traps are multipoles composed of any desired number of rods—i.e. the traps are quadrupoles, pentapoles, hexapoles, octapoles, etc. Such arrangement enables one to maintain a high “duty cycle” while avoiding “memory effects” and also reduces the power consumed in operating the analyzing quadrupole.

Abstract: An air barrier system is disclosed that allows the isolation of a central volume or one volume from another without the use of physical barriers. Toroidal vortices are formed at opposing end or ends of the volume to be isolated and prevent transport inward and outward. Contemplated applications include air curtains, oxygen tents, cleanrooms and testing chamber apparatus.

Abstract: A vortex generating apparatus has the capability of attracting and removably adhering one or more solid objects, with the improvement of being able to removably adhere to non-planar surfaces, e.g., concave or convex surfaces and/or inside and outside corners. Generally, the apparatus comprises an impeller housed within a shell. The vortex attractor generates a vortical fluid flow in the form of a helical or spiral-shaped flow. The fluid flow creates a low pressure region extending from the impeller end of the device. This low pressure region is contained by the walls of the fluid flow, thus directing the attractive forces toward a surface and minimizing effects of ambient fluid on the system. When the surface is part of a stationary object, wall, floor or ceiling, the vortex attractor may move toward and adhere to the surface. When the surface is part of a movable object, the vortex attractor may attract the object and maintain the attracted position.

Abstract: A novel drive for a lifting platform utilizing a simple propeller, impeller, or gas turbine is disclosed. The axial air rotation from the drive is eliminated in order to permit the development of a partial toroidal vortex which efficiently maintains a raised air pressure zone beneath the lifting platform. The axial components are eliminated by means such as flow straightening vanes, which may also serve to control lateral motion of the lifting platform. The system can also be easily modified to function as an attractor device. Overall, the present invention explores the effect of vortices, both cylindrical and toroidal, and seeks to optimize their effects.

Abstract: The present invention relates generally to time-of-flight mass spectrometers and discloses an improved method and apparatus for analyzing ions using a time-of-flight mass spectrometer. More specifically, the present invention comprises two or more electrostatic reflectors positioned coaxially with respect to one another such that ions generated by an ion source can be reflected back and forth between them. The first reflecting device is an ion accelerator which functions as both an accelerating device to provide the initial acceleration to the ions, and a reflecting device to reflect the ions in the subsequent mass analysis. The second reflecting device is a reflectron which functions only to reflect the ions in the mass analysis. During the mass analysis, the ions are reflected back and forth between the accelerator and reflectron multiple times.
