Patent CA-1103646-A (CA)

Abstract: 1957-39a ABSTRACT OF THE DISCLOSURE            The housing of a gate valve has a forged lower section and a forged bonnet.  The lower section has two halves which are mirror symmetrical to each other with reference to the central plane of the gate and are bonded to each other by a circular welded seam.  A circular or oval welded seam connects the lower section to the bonnet, and the lower section has a guide groove for the gate.  The groove is bounded by two surfaces forming part of circular surfaces whose centers are located on an axis including the center of curvature of the seam between the two halves of the lower section.  This simplifies the machining and assembly of the lower section because the surfaces bounding the guide groove can be machined simultaneously with the edge faces bounding the seam between the halves of the lower section.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention comprises a method of transmitting information from a central ground station to at least one mobile auxiliary ground station via at least one base station.  The auxiliary ground stations are located within the transmitting range of at least one base station, and are provided with a receiving device having a control unit and a memory.  In accordance with this method, a block of messages cyclically repeated within a time frame is transmitted over a single frequency from the central ground station to the base stations.  Each of the messages within the block includes an address code which corresponds to the area code of the region adjacent a corresponding base station.  The base stations transmit the block of messages over a single frequency to receiving devices located in the mobile auxiliary ground stations where those messages corresponding to a selected area code are recorded and then played back.  That is, the recorded messages are converted to an information signal for use by the operator of the mobile auxiliary ground station.  In most cases, the recorded message is played back to provide an information signal in audio form.  If the message is changed, the changed message is recorded and played back as an audio information signal to the operator.

Cecco ABSTRACT OF THE DISCLOSURE          The eddy current probe consists of two coils mounted coaxially with each coil capable of separate axial adjustment.  The coils are connected to the adjacent arms of an AC bridge circuit which can be balanced at the desired test frequency.  The voltage output from the AC bridge due to lift-off or defects is the difference between the voltage change of each coil.  The coils are adjusted axially to provide a voltage output due to lift-off which is in the order of 90° with regard to the voltage output due to shallow defects making the latter simple to detect.  A thin conducting shim may be positioned between one of the coils and the test surface in order to further rotate the lift-off signal of that coil.

Abstract: BINARY SCAN SYSTEM          ABSTRACT OF THE DISCLOSURE         An original image is reproduced on an electro-photographic member with a series of binary data bits having a statistically valid count corresponding to the relative density of the original image.         A sensor senses the density value of individual information forming structure or structures in incremental areas of the original image and converts the density values into a series of binary data bits, one bit per incremental area.  An imager receives the binary data bits and forms one binary element on the charged electrophotographic member surface in response to each bit.  The elements formed on the member surface correspond in sense to the binary data bits from the sensor and the elements are formed in incremental areas of the member corresponding to the incremental areas of the original image from which their respective binary data bits were produced.         An aperture of the sensor which determines the size and configuration of the incremental area scanned is adjustable to approximately the size and configuration of the information structure and a threshold level value of the sensed density values is adjustable to the mean of the sensed densities of the original image so that a sensed density value above the threshold value produces a binary bit of one sense and a sensed density value below the threshold value produces a binary bit of the other sense to produce the statistically valid count of the series of binary data bits.
