Abstract: Stabilized rotating sailing rig for boats formed by a mast, a boom perpendicular to the mast, and one or more sails bent to the common boom and to the mast; rig capable of freely rotating with all its elements, around a vertical axis, with the important and novel characteristic that the top of the mast is stabilized by shrouds and/or stays which tie it to the periphery of the deck or decks of the boat without jeopardizing the rotation of the rig around its vertical axis. This top of the mast stabilization also permits the use of prow fixed sails.

Abstract: A device for concreting and molding gutters includes runners configured to slide over ground. A mold forms the concavity of a gutter and a hopper, with a closure for pouring of concrete into a trench previously excavated in a form of the gutter. The runners have an extendable, rear extension configured to be raised and lowered by a hydraulic cylinder, with the runners further including sides. The sides forming lateral parts of a concreting hopper and a means of attachment for vibrators for vibrating the concrete. The mold includes a structure for attachment to the sides of the runners and to an arm of a backhoe or tow machine, with the mold structure complemented by plates, attached using hinges to the structure of the mold and using pipe turnbuckles, enabling variation of inclination of the mold.

Abstract: A system and method for controlling the output power of a heat source. The system includes a user interface so that a user may select the power required from the heat source, a power supply, and a controller that receives a rectified signal having a work ratio that corresponds to a nominal voltage of an alternating voltage signal corresponding to a phase of a power supply. The controller is configured to control the output power of the heat source in accordance with the power selected by the user, and modifies, if necessary, the work cycle of a power signal linked to the heat source in accordance with the work ratio in order to compensate possible differences in the nominal voltage between different power supplier.

Abstract: A delivery method and system allows a delivery vehicle to deliver in resident lanes. A delivery provider selects a delivery vehicle to perform the delivery. The delivery vehicle has a mounted transponder that emits a unique identifying signal to a reader at the resident lane. The reader may also be operable to capture an image of the license plate of the vehicle for identification. The delivery provider relays the identifying signal of the delivery vehicle to a data storage. During delivery, the vehicle engages a resident lane in the community. The reader at the resident lane identifies the identifying signal emitting from the transponder or the captured image. The reader communicates with the transponder. Depending on the identifying signal emitted from the transponder, the reader can grant the vehicle access for one-time entry through the resident lane unique. The one time entry can be resubmitted for subsequent deliveries.

Abstract: Improvements are provided in the detection of atmospheric vapors by ionizing them near ambient pressure, and analyzing them as ions. Lowest detection limits of parts per quadrillion (ppq) concentrations are enabled by a combination of improvements, including the use of a filter to remove occasional intense signal from explosive particles. Several sources of chemical background are identified and solutions for their reduction or elimination are presented. Gains in response time may be achieved by operating at elevated temperature. When the ionizer is an electrospray source, the use of high boiling point solvents is indicated. An increased selectivity is achieved by operating a differential mobility analyzer (DMA) in series with a mass spectrometer. However, ppq sensitivities require various improvements in the DMA system including a special coupling to the ionizer, controlling the temperature in the DMA pump circuit, avoidance of induction on the DMA electrodes from heating devices, etc.

Abstract: A self-supporting rotary rigging and, more specifically, a rigging that has a circular platform adjacent to the deck of the vessel, which makes it possible to control the rotation of the rigging and to install rotary stays and shrouds, which assists in stabilizing the rigging. The rigging is characterized by the existence of a small common boom securely joined to the base platform and to which are fastened the backstay and forestay, all the aforesaid making the rigging very secure and enabling the backstay and forestay to be capable of downward movement. There is a base crosstree, likewise securely connected to the platform, perpendicular to the stays, and to the end thereof are fastened the shrouds, enabling the later to work at a suitable angle. In addition, there is a tunnel across the lower part of the mast, which allows passage from one side of the rigging to the other.

Abstract: A method for fast and accurate recognition of species contained in trace amounts in complex mixtures such as ambient air or biological fluids is taught based on the use in tandem of one or several differential mobility analyzers (DMAs) and possibly also a mass spectrometer (MS), all arranged in series. The two DMAs operate in different regions of the ion drag versus drift velocity curve (for instance, linear versus nonlinear regions), hence separating according to more than one independently discriminating parameters of the ion. Very high discrimination can be achieved even with a single stage of mass spectrometric separation by selecting a narrow range of ions with the DMA, and analyzing them in the MS, first without fragmentation, and then with fragmentation. This process does not require necessarily a tandem MS when fragmentation takes place in the inlet region of the MS.
