Abstract: Improvements have been made to the Electrospray and Atmospheric Pressure Chemical Ionization source chambers interfaced to mass spectrometers to simplify source performance optimization and source operation and to improve system sensitivity. The atmospheric pressure ion source procedure for optimizing performance has been simplified by adding windows along the sides of the atmospheric pressure ionization chamber allowing direct viewing of the Electrospray and Atmospheric pressure ion sources during operation. A cylindrical lens which extends along the side walls of the atmospheric pressure chamber has been configured to be semitransparent for viewing into the chamber. This cylindrical shaped side lens is electrically isolated from the Electrospray liquid introduction needle and Electrospray chamber endplate.

Abstract: A pinch clip for a garment hanger, and a garment hanger having such pinch clip, is disclosed. The clip includes an opposable retaining member spring biased into a closed position against a flange formed on one end of the main support of the hanger. The main support includes a through-hole, gap, or opening through which the proximal finger-grip end of the retaining member may pass when the pinch clip is opened. The distal end of the retaining member abuts the flange when it is in the closed position. When force is applied to the proximal end, the clip opens, and the proximal end nests inside and passes through the through-hole. In this way, the clip can be made substantially coplanar with the main support of the hanger, and a more streamlined hanger is the result. The invention may also be molded from a single mold, thereby simplifying the manufacturing process.

Abstract: An integrated MAGLEV (Magnetic Levitated Vehicle) system consists of permanent or preferably superconducting vehicle-mounted magnets which interact with both active and induced track-based currents. The magnets on the vehicle which are used for propulsion serve the dual purpose of realizing both levitation and lateral stabilization (guidance). The contribution offered by this invention is that it is able to provide propulsion, levitation, and guidance using a single type of track-based coil interacting with a singular type of magnetic field which is affixed to the vehicle. The realization of multiple functions with a single coil reduces the cost and enhances the efficiency of this MAGLEV system. In the main embodiment of this invention, propulsion currents are injected into brushes sliding along brush contact surfaces on the rail. Motion induced currents in the coils realize both the necessary levitation and guidance forces for the vehicle.

Abstract: An expandable dental implant which is less traumatically inserted and can immediately receive functional loading to support a dental prosthesis upon insertion into the patient's mouth. The expandable implant is constructed as an inflatable balloon, which has a first, relatively smaller diameter prior to insertion into the patient's mouth. The implant is provided with an insertion end, for insertion into a formed bore in the patient's jaw bone. Upon insertion into the bone, the balloon can be inflated into a second, larger diameter profile by filling the hollow interior of the balloon using an appropriate hardening material, which applies pressure against the interior walls of the implant, allowing the implant to inflate within the bone and to fixate. Upon inflation of the implant, a dental crown can immediately be added to the implant's attachment end.

Abstract: A tension pole comprising an outer, lower pole piece and an inner, upper pole piece. The bottom of the lower pole piece and the top of the upper pole piece are provided with rubber feet. The pole pieces are telescopable to adjust the length of the tension pole. A locking mechanism is provided which further telescopes one piece relative to the other to lock the tension pole between floor and ceiling with the rubber feet absorbing at least a part of the telescopic movement due to the locking action. Locking is done by turning a handle. Also, the locking/telescoping action simultaneously frictionally engages the pole pieces together to further secure the device.

Abstract: A Time-Of-Flight mass spectrometer is configured with a pulsing region and electronic controls to cause the directing of ions to a surface in the Time-Of-Flight pulsing region. The population of ions resulting from the collecting of said ions on or near said surface is subsequently accelerated into the Time-Of-Flight tube for mass to charge analysis. Ions produced away from said surface located in the pulsing region of a Time-Of-Flight mass spectrometer can be directed to the surface with high or low surface collisional energies. Higher energy ion collisions with the surface can result in Surface Induced Dissociation fragmentation and the resulting ion fragment population can be accelerated into Time-Of-Flight tube where the ions are mass to charge analyzed. Ion mass to charge selection can occur prior to directing ions to the pulsing region surface allowing MS/MS Time-Of-Flight mass analysis with SID.

Abstract: A lamp having a hydrocarbon fuel source is provided. The lamp includes a housing and a fuel source containing hydrocarbon fuel. A mantle is disposed inside the housing and is in communication with the exit of the fuel source. A cover is attached to the housing in thermal communication with the interior housing. The cover has a slot and a replaceable pad is disposable in the slot; the pad preferably contains a volatilizable substance. When the fuel egresses the fuel source and is ignited and burns, heat generated from the fuel is conducted through the cover to the pad so that the volatilizable substance is volatilized. The volatilizable substance is preferably an insect repellent. The lamp may be portable such as a flashlight. A separately attachable cover that may retrofit an existing lamp is also provided.

Abstract: A remote controlled system for remotely controlling a high load device, such as the defrosting cycle of a self-defrosting refrigerator, is provided. The system includes a data interface to receive commands from an electricity supplier and to transmit those commands via the power line to the refrigerator. The refrigerator is equipped with a power line interface to receive the commands from the power line and transmit the commands to a defrost sequencer. Between the power line interface and the defrost sequencer may be provided another interface that converts the commands into a digital signal more suitable for the defrost sequencer, which is typically a microprocessor.

Abstract: A mounting bracket for a tension pole or other structure is provided. The bracket is provided with a spine which is fittable into a channel of a tension pole, scaffolding, or other primary support. The spine is preferably a parallelogram or a half-dovetail in section. A rotatable locking flange is provided in a break in the spine. When the locking flange is in the unlocked position, it is coaxial with the spine. When the locking flange is rotated into the locked position, the axis of the flange is orthogonal to the axis of the spine, and at least one of the ends of the flange juts out beyond the profile of the spine and behind the angled walls of the channel of the primary support. A handle is provided to facilitate rotation of the locking flange from an unlocked position to a locked position and back.

Abstract: A nail for fixing the position and shape of broken long bones is provided. The nail has a shank having a central main body and longitudinal chamber-like expansion elements attached to the central main body which are expandable while in situ. The expansion elements run substantially the length of the shank and are preferably arranged substantially equiangularly around the central main body. When the expansion elements are expanded, a cross-section of the central main body is expanded. The central main body may be provided with channels into which the expansion elements may be disposed.
