    摘要： A method and a safety device for the protection of a user's eye, or other radiation sensitive system, from a pulsed radiation emitted by a radiation source by means of an electro-optical shutter used in conjunction with the radiation source. The electro-optical sutter defines the field of view of the user or of the system and is capable of being switched by an electrical voltage signal from a transparent state to an opaque state within a response time .DELTA.t.sub.r. The method comprises applying to the electro-optical shutter the electrical voltage signal at an operational time interval .DELTA.t.sub.o, prior to the emission of each radiation pulse and keeping the electro-optical shutter in its opaque state until the radiation pulse is emitted. The operational time interval .DELTA.t.sub.o is at least slightly longer than the response time .DELTA.t.sub.r so that, by the time of emission of each radiation pulse, the electro-optical shutter is in its opaque state.

    摘要： An ultrasonic test set is calibrated in terms of its frequency characterization by establishing a response trace on a monitor screen of the test set when the probe of the test set is applied to a standard test article, a digitizing camera is arranged for scanning the trace on the test set monitor, and a digital computer receives the digital output signal on the digitizing camera and processes the signal by sampling the signal trace at discrete points with respect to time; the digital computer provides an output on output means such as a monitor screen and/or printer which provides information on the frequency characterization of the ultrasonic test device and includes a frequency spectrum. The apparatus can be implemented by a combination of commercially available and known separate elements providing a cheap and effective apparatus and method for calibration purposes.

    摘要： This invention relates to a vacuum cleaner attachment for the purpose of simultaneously cleaning a plurality of slats of a Venetian blind and comprises: A molded body 20, a vertical handle 24, a tubular neck 22, having communication with the body and adapted to be connected to a vacuum cleaner hose (not shown), rectangularly shaped fingers 26 which have communication with the body and extend out horizontally from the side of the body opposite the handle, and each opposing finger face having apertures 44 on a longitudinal center axis, rectangularly shaped brush plates 38 having approximately the same lateral dimensions as the finger faces and having apertures 40 in registry with apertures on the opposing finger faces, brush plates slide on and off the finger faces by way of a channel 34 and lip structures 32 and small tabs 48 on the lip structure lock the brush plates in place, bristles 46 will be affixed to the brush plate faces and extend towards each other when locked in place on opposing finger faces. When in use the operator will grip the handle and insert the fingers of the attachment between the open slats of a Venetian blind, thereby simultaneously sandwiching five of the slats with opposing brushes and while extending the fingers lengthwise between the cords of the blind the attachment will loosen and remove the dirt which will then be carried away by air currents through the apertures and passages of the fingers, body and neck.
