A mounting system and method for security screens for use with windows having an exterior-facing accessory groove at the outer perimeter of the window frame is disclosed. The mounting system and method according to the present invention reduces materials cost for manufacture of security screens while improving aesthetics of the installation and permitting installation of security screens either at the construction site or during window manufacture, while preserving the window manufacturer's warranty. Exemplary embodiments both with and without a subframe are described.

Security screen mounting system and method therefor

A mounting system and method for security screens for use with double-hung windows and other windows having an integral screen track is disclosed. The mounting system and method according to the present invention reduces materials cost for manufacture of security screens while improving aesthetics of the installation and allowing installation to be accomplished from the interior side of the window, and permits installation of security screens either at the construction site or during window manufacture, while preserving the window manufacturer's warranty. Exemplary embodiments both with and without a subframe are described.

A towing truck incorporating both an elevated deck and an improved elevated wheel lift for towing and hauling vehicles is described. The elevated wheel lift comprises rotatable tire braces to aid in smooth loading and firm support of the towed vehicle's tires during towing.

Towing and wrecker truck construction having an extensible wheel lift

A towing truck incorporating both an elevated deck and a stinger for towing and hauling vehicles. Both are hydraulically operated with the deck sliding along a pair of oppositely spaced rails which are pivotally secured to the framework of the truck. A locking assembly is disclosed which engages the deck's substructure, thereby restraining the deck in place.

An air preheater water jet apparatus is provided for cleaning fly ash, soot and the like from a rotating or stationary heat exchange basket on a air preheater used to improve the efficiency of a boiler in an electric utility generating plant. The air preheater cleaning apparatus includes a cleaning assembly with water jet nozzles, thereon, attached to a carriage which moves along a track, such as a channel beam, affixed radially above and adjacent to the air preheater basket. A drive assembly and an idler bracket assembly with a roller chain therebetween are disposed on the channel beam. The carriage assembly is attached to the roller chain and as the carriage is driven, the cleaning assembly is moved along the channel beam. Thus, when the basket, or the air preheater cleaning apparatus, is rotated and the carriage is moved inward, a circular path of the basket is cleaned. Additionally, a variable speed motor control apparatus is used to increase the air preheater rotational speed as the carriage assembly moves inward, such that the relative speed between the cleaning assembly and the air preheater basket remains constant as inward movement occurs.

An integrated control system, specifically transportable on water between offshore wells, includes mixing and blending subsystems, a pumping subsystem, a proppant subsystem and a control subsystem for controlling the other subsystems in a unified manner from a common control location.

Integrated blending control system

A data monitoring system includes a display unit for communicating with an operation that has characteristics which are to be monitored, a recording unit located remotely from the environment of the monitored operation, and a local area network interconnect circuit for connecting the display and recording units. The local area network circuit allows multiple display units to be connected to a single pair of electrical conductors. Each display unit has at least one dual microcomputer configuration interconnected by a shared dual port random access memory. A third microcomputer is located in the recording unit for communicating over the local area network circuit with one of the microcomputers in the display unit.

Local area network data transfer system

A data acquisition apparatus includes two microcomputers interconnected by a shared dual access digital storage device. One microcomputer obtains the data related to the monitored condition, stores it in the digital storage device, and modifies a status word which is monitored by the other microcomputer. When the other microcomputer detects a change in the status word, it takes the data from the shared digital memory and moves it into its own memory for subsequent use or transfer. The data acquisition apparatus also includes, in a preferred embodiment, analog switches and a digital to analog converter by which external analog devices can be controlled to change the monitored operation.

Data acquisition module and method

An enclosure for electronic equipment includes an outer housing having an inner housing mounted therein. The inner housing has a fan and air deflector members mounted therein for maintaining a controlled circulation of air flow within the interior region of the inner housing so that air within the interior region is moved in heat exchange relationship with a heat sink member extending into the inner housing. The heat sink member in the inner housing is connected by thermal diodes with another heat sink member attached to a side wall of the outer housing. Another fan directs an air flow over the heat sink member attached to the side wall of the outer housing. A third fan is mounted within the interior region of the outer housing, but externally of the inner housing, for providing air circulation within the interior region of the outer housing.
