Abstract: A drive train for a wind-up injection device is described. The drive train includes a torsional energy storage adapted to be loaded or unloaded by a rotatable element, a rotatable user handle, a rotationally driveable expelling mechanism adapted to expel the liquid drug, and a clutch element coupled with the torsional energy storage via the rotatable element and including a ratchet for maintaining the rotatable element at one of a number of discrete angular positions against the torque of the torsional energy storage. The clutch element is adapted to transmit the torque from the user handle to the torsional energy storage, or alternatively from the torsional energy storage to the expelling mechanism. The ratchet is switchable from one position to an adjacent position by a torque transmitted from the user handle to the torsional energy storage. The drive train is adapted to dampen torque peaks visco-elastically and/or visco-frictionally.

Abstract: In one embodiment, thermite matches are provided. For instance, thermite matches as described herein may be constructed as a multi-staged formulation comprising an outer ignition tip, an optional inner transition tip, and a bulk fuel thermite stage. The outer ignition tip may comprise an ignition compound that can be struck/scraped against an abrasive counter-chemical surface (e.g., red phosphorous) to initiate the reaction. The outer ignition tip can reach a first burn temperature that can further ignite the inner transition tip stage, which can in turn burn at a temperature that reaches the ignition temperature of the bulk fuel thermite. The high burn temperature of the thermite match may then be used to ignite other materials, such as hard-to-ignite materials, such as a thermite rod for cutting or welding. Other embodiments provide for thermite match handles and a two-piece ignition thermite matches.

Abstract: In one embodiment, a portable thermite fire starter kit is provided. For instance, one or more small pieces or solid blocks of thermite may be contained within a portable kit container along with one or more ignition items. The ignition items may comprise thermite matches. In one embodiment, the ignition items are kept separate from the pieces of thermite. In one embodiment, one or both of the thermite pieces and/or thermite matches are constructed as multiple layers of progressively ignitable materials and/or compounds. In particular, the layers may start at a first layer and that can reach a first burn temperature that is at least a subsequent adjacent layer ignition temperature, where each subsequent intermediate layer leading to the thermite progressively increases in ignition temperature to not more than a previously adjacent layer burn temperature and also increases in burn temperature to at least a subsequent adjacent layer ignition temperature.

Abstract: In one embodiment, an environmental sensor array monitors pre-filter airflow to a fuel cell with an air filter, and senses amounts of filter exposure of air contaminants in the monitored pre-filter airflow. The environmental sensor array may then correlate the sensed amounts of filter exposure over time to a long-term adsorption limit of the air contaminants for the air filter, determining a lifetime usage level of the air filter. Accordingly, the environmental sensor array may provide an indication of the lifetime usage level of the air filter. In another embodiment, the environmental sensor array may also monitor post-filter airflow to the fuel cell, and senses instantaneous levels of post-filter air contaminants. In response to the instantaneous level of any particular air contaminant of the post-filter air contaminants being above a respective threshold level, the environmental sensor array may protect the operation of the fuel cell (e.g., de-rate, shut down, etc.).

Abstract: A Step Flow control device and methods therefore provide instructions to control operation of various absorption chiller components based on measured load or temperature information. Operating an absorption chiller according to Step Flow balances the flow of heat energy through the absorption chiller to increase efficiency and prevent crystallization. The control device may be integrated into various components of an absorption chiller or may be remote therefrom. In this manner, Step Flow can be used in new absorption chiller installations or be used to retrofit existing installations.

Abstract: Demand Flow operates chilled water plants at substantially improved efficiency, regardless of plant load conditions. In general, Demand Flow utilizes an operating strategy which controls chilled and condenser water pumping according to a constant Delta T line, which is typically near or at design Delta T. This reduces or eliminates Low Delta T Syndrome and reduces energy usage by chilled and condenser water pumps for given load conditions. Operation of chilled water pumps in this manner creates a synergy which generally balances flow rates throughout the plant, reducing undesirable bypass mixing and energy usage at air handler fans and other components of the chilled water plant. At plant chillers, application of Demand Flow increases the refrigeration effect through refrigerant sub-cooling and superheating, while preventing stacking. Demand Flow includes a critical zone reset feature which allows the constant Delta T line to be reset to adjust to changing load conditions.

In this manner, the qualification system provides accurate analysis while reducing data entry. In addition, the qualification system may accept varying amounts of data such as to reduce percentage error or the like in its analysis.

The invention also claims an air tube system for transferring security documents, the system including a controller adapted to control a number of control stations (21A, 21B, . . . 21G) for selectively transferring carriers along interconnecting tubes between loading stations and destination stations.

Abstract: In an AC magnetic tracker one or more multi-axis field sources, each operating at a different frequency, or frequency set, are detected and tracked in three-dimensional space, even when wireless or otherwise not physically connected to the tracking system. Multiple sources can be tracked simultaneously as they each operate with their own unique detectable set of parameters. The invention not only provides the ability to uniquely identify one or more sources by their frequencies, but also to synchronize with these frequencies in order to measure signals that then allow tracking the position and orientation (P&O) of the source(s). Further, these sources need not be present at the time of system start-up but can come and go while being detected, discriminated and tracked. It also should be noted that application of such systems in multiples with more sensors not synchronized to a source or sources also could be employed to give the reverse appearance of a known source phase and incoherency with the sensors.
