Patent ES-386296-A1 (ES)
Title: Rigid base earth compactor
IPC: E01C19/34
Filed: 1970-12-10
Abstract: An earth compactor having a unitary base with downwardly facing convex surfaces. A first vibrator assembly is mounted generally centrally of one surface and a second vibrator assembly is mounted generally centrally of the second surface. Each assembly includes an eccentrically mounted weight. The weights are rotated at a speed ratio of 2:1 relative to each other and are initially positioned so both weights are up relative to the shafts on which they rotate. Such phasing of the weights provides an upwardly directed simultaneous unweighting action which facilitates steering and moving the machine by an operator. In one embodiment the weights have the same mass. The impacts exerted on the earth by this machine have a complex waveform, including a band of frequencies which provide for optimum compacting of earth of various particle sizes and consistencies. In a second embodiment the slower rotating weight has a greater mass than the faster rotating weight. In another embodiment, the portion of the base associated with the slower rotating heavier weight is heavier than the portion of the base associated with the lighter faster rotating weight.

Title: Static network protective relay
IPC: H02H3/40
Filed: 1972-09-05
Abstract: A static protective relay comprises a power directional unit for controlling a circuit breaker which couples a primary feeder or a source of supply of a 3-phase power distribution system to an alternating current secondary network through a network transformer. The power directional unit senses reverse power flow above a preselected threshold level from the network to the network transformer to energize a tripping coil of the circuit breaker. Included in the power directional unit is a voltage deriving circuit producing a voltage proportional to the system current through the circuit breaker, a modulator which modulates the voltage by a voltage proportional to the system voltage at the circuit breaker to obtain an output proportional to real power flow through the circuit breaker, and a detector which energizes the tripping coil upon the presence of a reverse power flow signal from the modulator. The power directional unit also includes a source of variable bias comprising circuitry for providing a bias signal which varies both in magnitude and in phase and is a function of the phase angle of the phase current. The variable bias is supplied as an input to the detector to provide a power directional unit exhibiting improved sensitivity to highly capacitive phase currents.

Title: Method of and system for transmitting two different messages on a carrier wave over a single transmission channel of predetermined bandwidth
IPC: H04J1/14
Filed: 1978-12-22
Abstract: In a radio broadcoast channel, an additional message is superimposed on the normal message so as to be inaudible to the listener. To accomplish this, the additional message, consisting of digital signals, is modulated on a subcarrier lying in the ear-physiological masking range of the normal message. During breaks and very quiet intervals of the normal transmission, the signal transmission is interrupted because no masking occurs during those times. To make this possible, the transmission of the normal message is delayed by at least one signal length.
