摘要:
A method for controlling customers' access to services on a broadband network. The method uses a circuit identifier, unique to each customer, to compare service requests with service entitlements. The network provider flows the circuit identifiers to the service providers where relationship between the circuit identifiers and the service entitlements is established in service orders. Service providers flow the service orders back to the broadband network though a standard business system interface. The relationship between the circuit identifiers and the service requests is accomplished at the Broadband Digital Terminal that interface the customers to the broadband network. The circuit identifiers also permit sorting of data bases containing logs of service requests and logs of maintenance actions.

A ladder leveler device to level and stabilize a ladder on an uneven surface, comprising a generally rectangular shaped base plate having a plurality of threaded holes located on each wide end, a plurality of hollow jack screws complimentary to and threading through the plurality of threaded holes on each wide end, a plurality of Allen head bolts reposing freely within the hollow jack screws, washers and lock-nuts on the plurality of Allen head bolts, a square tubular guide attaching longitudinally to the center of the rectangular shaped base plate, a square tubular shaft which is slidable within the square tubular guide, a plurality of longitudinally aligned holes in the center of one longitudinal side of the square tubular shaft, a restraint on one end of the square tubular shaft, a longitudinal cut-out in the center of the side of the square tubular shaft opposite the longitudinal side with the plurality of longitudinally aligned holes, a pivoting foot securing to the square tubular shaft by means of a bolt, a plurality of spacers and a locknut, and a spring biased pin means attaching to the center of the square tubular guide having a circular shaft extending through the square tubular guide, the longitudinal cutout, the plurality of longitudinally aligned holes, and a complimentary hole on the square tubular guide opposite where the spring biased pin means is mounted.
摘要:
An improved powder delivery system for use in dispensing powder to a printing press. The improvements include an agitator system for the powder reservoir, a wiper block for use with a curved feed roller, a split air flow amplifier which is openable for cleaning, a flow-through rotary manifold for distributing powder to press and an improved powder spray block. The foregoing elements minimize the flow restrictions and enhance air and powder flow through the system. A control panel is provided at the operator's console which is remote from the mounting position for the powder delivery apparatus. The control panel provides for, among other things, the delivery of powder at a fixed rate regardless of press speed or in accordance with variations in press speed. For example, in accordance with a factory determined linear relationship or an operator entered relationship. Such data can be stored for future reference and use.
摘要:
An optical sensor in which acceleration, acoustic velocity, or displacement (vibration) causes a corresponding shift in the center wavelength of the sensor output. The sensor can be coupled to a high-speed interferometric interrogator through an unbalanced fiber interferometer. The unbalanced interferometer functions to translate optical wavelength shift into phase shift, which is easily demodulated by the interrogator. A method of measuring acceleration uses the sensor.

A method of measuring acceleration using an optical sensor. In the optical sensor, acceleration, acoustic velocity, or displacement (vibration) causes a corresponding shift in the center wavelength of the sensor output. The sensor can be coupled to a high-speed interferometric interrogator through an unbalanced fiber interferometer. The unbalanced interferometer functions to translate optical wavelength shift into phase shift, which is easily demodulated by the interrogator.
