摘要:
A flow measuring device includes a housing having an inlet, an outlet and a passage extending between the inlet and outlet, a shaft disposed within the housing and rotatable about a central axis and a flow detector mounted on the shaft and disposed partially within the passage, such that fluid flow through the passage rotates the detector about the axis. A magnet is mounted on the shaft and spaced axially from the detector and a sensor disposed within the housing and configured to sense rotation of the magnet as the shaft angularly displaces about the central axis so as to detect angular displacement of the flow detector. Preferably, the sensor includes a switch adjustable from open and closed states when either one of the poles of the magnet is proximal to the switch. A processor is connected with the switch and determines flow volume and/or flow rate through the passage.

The present invention provides an apparatus for venting an airspace formed between an ornamental window and a protective panel. The venting means includes at least one pair of vent openings, one for air to enter the airspace and one for air to exit. These vent openings include a path through the frame holding the protective panel to an interior opening which is to the airspace. The vent openings, the paths and the interior openings must be of adequate size to minimize the range of temperature and moisture within the airspace. It is recommended that effective vent openings are at least one square inch for every 2000-2500 square inches of ornamental window.

Signatures indicating potential problems can be used by a predictive support component. The predictive support component can check to see if a signature matches data for a data source associated with the software.

A device for dispensing a viscous fluid, such as grease gun for dispensing lubricant. The grease gun delivers lubricant with a selectable variation in pressure and/or output. It includes a reservoir, a pump having a reciprocating plunger, an electric motor driving the pump, and a variable speed transmission for transmitting power from the motor to the pump. The transmission has at least two different output speed settings adapted to be selected for reciprocating the plunger at different cyclical frequencies. A cycle indicator provides an indication corresponding to a quantity of lubricant dispensed. Embodiments of the grease gun include a pressure relief valve which inhibits damage due to an over-pressure condition, and a circuit breaker which inhibits damage due to electrical overload.

A method of operating a lubrication system for lubricating a bearing in a housing includes the following steps: dispensing a quantity of lubricant within the bearing housing; monitoring a containment period of time during which the lubricant quantity is contained within the housing; determining when the containment time period exceeds a predetermined value of time; and dispensing another quantity of lubricant within the bearing housing when the containment time period exceeds the predetermined time value such that the other quantity of lubricant displaces the quantity of lubricant from the bearing housing.

A case for holding eyeglasses defines the head band of an eyeglass retainer. The bow retaining straps of the retainer are secured to the outer edges of the case/head band. A separate, flexible sheet conforms to the shape of and is secured to the head band case for defining a pocket between the base and the sheet. A through slot in the sheet provides access to the pocket, permitting the folded eyeglasses to be inserted through the slot and encased between the base and the sheet while attached to the retaining straps.
