Latest Patents

Hooper's latest patents include a printer/plotter style system designed for confined installations. This invention features a recording machine, such as an electrostatic printer or facsimile plotter, which incorporates a housing construction that allows for an overall external width reduction without sacrificing functionality. The design includes a liftable lid and a method of cross-bracing, making the machine serviceable through a removable bottom closure panel that supports an electronic chassis. Additionally, the operating stations consist of a recording assembly, which includes both an electrostatic latent image recording station and a toner developing station, as well as a web-cutting assembly. Each of these components is designed to be yieldingly held together by a hinged latching panel, ensuring a secure and efficient operation.

Another significant patent by Hooper is a keying waveform generator for a double beam spectrophotometer. This device employs a rotating optical chopper to direct a beam of electromagnetic radiation alternately through sample and reference channels to a photomultiplier tube. The invention utilizes a beam interrupter in combination with a photodiode and a photocell to generate a square wave signal that is temporally related to the rotation of the optical chopper. This signal is then integrated to produce a triangular waveform, which aids in the detection of dark current generated by the photomultiplier tube and synchronizes analysis circuitry with the passing of the beam.
