Patent ES-471288-A1 (ES)
Title: Semiconductor field-effect sensor for an electric or magnetic field.
IPC: G01R29/08
Filed: 1978-06-30
Abstract: A high sensitivity, low noise, broad bandwidth channel conduction field sensor device is described. The conductive channel is configured to create an exceptionally narrow, undepleted conduction channel of approximately filamentary form. The filamentary conductive channel so formed is provided with a source at one end of the channel and two or more laterally spaced drains at the other end thereof. Electric or magnetic fields may be utilized to deflect a stream of charge carriers traversing the conductive channel from the source toward the drains utilizing the depletion width modulation effect of the fields upon the boundaries defining the conductive channel portion. Modulation of the depletion zone width and depth along the channel sides effectively moves the stream of carriers and the conductive channel area to overlap one drain more than another. This develops a differential drain current balance which can be utilized to provide an output signal. Width and length criteria for defining a filamentary channel structure are described for the ultimate desired configuration and size which are to be obtained. As noted, operation of the device is based upon modulation of the width and depth of the depletion zone boundaries defining the conductive channel. An increased signal output is obtained by reducing the width of the channel to eliminate excess carriers normally found in wide channel devices and, further, by making the depletion zones as large a portion of the total channel width as can be obtained.

Title: Bead setting apparatus with retractable flange
IPC: B29D30/32
Filed: 1979-12-20
Abstract: An apparatus and method of setting a bead ring against the plies of a tire carcass on the shoulder of a building drum includes a carrier member with a retractable bead support flange. As the carrier member pushes the bead firmly against the carcass plies, the bead support flange is also pushed against the carcass plies, and the flange partly retracts under the pressure. Then, a fluid operated piston drives the support flange further away from the carcass plies, leaving the bead ring almost unsupported, but pressed firmly against the carcass plies on the building drum. The carrier member then retracts away from the building drum, leaving the bead ring in place on the building drum shoulder and ready to have the carcass ply end portions wrapped around it.

Title: Protection system for high voltage transmission lines.
IPC: H02H3/40
Filed: 1982-09-10
Abstract: Disclosed is a system that provides protection for a high voltage transmission line. The system employs improved polarizing and operating signals for both a phase selector relay and a distance measuring relay. The improved polarizing and operating signals provide an accurate out-of-phase relationship during the presence of normal conditions existing on a high voltage transmission line and an in-phase relationship during the presence of fault or abnormal conditions existing on the high voltage transmission line. The accurate phase relationships are utilized by phase comparator circuits of each of the phase selector and distance measuring relays to obtain desired operating characteristics for each relay. In another embodiment, the desired operating characteristics of the phase selector and distance measuring relays are obtained by an amplitude comparator circuit. In a still further embodiment, the distance measuring relay is operated under the control of the phase selector relay so as to provide the proper desired phase selection and protection of the high voltage transmission line.
