摘要:
A battery charging device which is driven by a torsional spring. A gear train driven by the spring is coupled with a wheel having peripheral teeth. A control lever is reciprocated pivotally by a small spring to engage the teeth of the wheel in a manner to control its rotation. The wheel in turn applies impulses which help to keep the lever in motion. The gear train is also coupled with an alternator such that the intermittent movement of the gear train is used to drive the alternator. The electrical current produced by the alternator is used to recharge a battery. An electric motor operates in combination with the switch mechanism to automatically wind up the torsional spring when it has been unwound below a preselected tension level.

A gas discharge display apparatus including a gas discharge display panel comprising a plurality of cells arranged in a column/row matrix. Cathodes are connected to the rows and anodes to the columns of the matrix. The cells are arranged in repeating groups each comprising at least two columns. Corresponding cells in each group are primed contemporaneously in a desired sequence whereby the last cell in the sequence to be primed is adjacent the first cell in the sequence to be scanned. In priming the cells each cell is discharged at a low level. Various types of priming loop sequences are disclosed.

A system includes a drill bit, and a tubular connected thereto. The tubular is configured to be rotated to rotate the drill bit and drill a length of a borehole and cemented in place. The tubular and the drill bit form a conduit to permit cement to be pumped through the tubular and the drill bit and into an annulus. The system also includes a collar disposed between the tubular and the drill bit. The collar includes a receptacle made from a drillable material, which has a profile that corresponds to a shape of a component deployed through the length of the tubular, and is configured to form a substantially fluid tight seal between the component and the drillable material when the component is seated in the receptacle. The collar and the component prevent backflow of the cement.

摘要:
A method of conveying a location information representing a physical location of a communication device (1) to another communication device (2) comprises acquiring (6) by the communication device (1) a first location information (11) and a second location information (17), the second location information being acquired (17) subsequently to the acquiring of the first location information (11) and detecting by the communication device (1) a deviation of the second location information from the first location information (18) representing a change of the physical location of the communication device (1). The method further comprises, triggered by the detected change of the physical location of the communication device (1), conveying (27) the most recently acquired physical location of the communication device (1) to the other communication device (2) by sending (26) a signaling message by the communication device (1) to the other communication device (2), the signaling message comprising either the second location information or the deviation of the second location information on the first location information.

摘要:
The present disclosure provides apparatuses, systems, and methods involving a spotter for depositing a substance on a submerged surface. The spotter comprises an outlet cavity defined at least in part by a spotting orifice, a first opening, and a second opening. The spotter also comprises a first conduit fluidly coupled to the first opening and a second conduit fluidly coupled to the second opening. The spotter is adapted so that fluid flowing through the first conduit and the second conduit is communicated among the first opening, the second opening, and a submerged deposition surface when the sealing orifice is sealed against the submerged deposition surface to form a deposition spot on the submerged deposition surface. The submerged deposition surface is within a liquid such that the liquid covers the deposition spot upon removal of the orifice from the deposition surface.
摘要:
A microwave excited ultraviolet lamp system with a data logging and retrieval circuit and method for operating the same. The data logging and retrieval circuit stores operational data in a cache memory using a FIFO data storage protocol. The contents of the cache memory are periodically copied to a larger removable memory so that the removable memory contains a relatively long historical record of the system operational parameters. The data logging and retrieval circuit includes a data port configured to load the contents of the cache memory into an external device when the device is coupled to the data port. A second data port allows the external device to supply power to the data logging and retrieval circuit so that data may be retrieved when the internal power supply is malfunctioning. Data stored in the removable memory may be protected so that it may only be accessed by authorized personnel.
摘要:
A rodent station includes a base with an entrance point and an exit point to allow a rodent to access the station. A hinged cover may be coupled to the base for housing an indicator device. The indicator device may be configured to show an operator that activity, such as capturing a rodent, has occurred within the rodent station. A killing device may be disposed in the base and configured to activate the indicator device upon being triggered by a rodent. The killing device may include an arm that rotates when triggered by the rodent. In one exemplary embodiment, a portion of the arm may contact a portion of the indicator device, resulting in an alert portion protruding from the cover of the rodent station, thereby indicating the triggering of the killing device. The indicator device may be, for example, a spring-loaded pop-up device or a rotating flag device.
