Patent ES-486623-A1 (ES)
Title: Driving machine including speed synchronized earth working traction wheel
IPC: B62D57/02
Filed: 1979-12-05
Abstract: The invention relates to a public works machine constituted by a frame, by moving members with which the said frame rests on the grounds, by a device for driving the said moving members and, by a wheel provided with teeth for penetration into the ground, which wheel is mounted to rotate about a horizontal and transversal axis, and is coupled to a device for driving it into rotation whilst being adapted to be held in one position wherein the distance between the axis of the said wheel and the ground is less than the distance separating said axis from the free end of a tooth, whereas a synchronizing mechanism holds substantially constant the ratio of the rotation speed of the wheel to the linear speed of the moving members. The profile of the active face of each tooth is an involute profile defined by the substantial lack of pressure exerted by said profile on the ground during the rotation of the wheel. The invention finds an application in the production of channeling machines.
Patent ES-488483-A1 (ES)
Title: Switching amplifier for driving a load through an alternating-current path.
IPC: H03F3/30
Filed: 1980-02-12
Abstract: An amplifier includes first and second switches coupled at a junction to form a series circuit. The series circuit is serially coupled with an inductor across a source of energizing potential. A capacitor couples the junction between the switches to a load. The switches conduct alternately under the control of a duty cycle modulator. The duty cycle modulation tends to vary the amplitude of the two opposite-polarity portions of the signal appearing across the load. A clamp is coupled to the junction of the series switch circuit and the inductor. The clamp operates during a first of the two alternate switch conduction intervals to clamp the voltage across the inductor at a fixed value. Since a direct voltage cannot be established across an inductor, the voltage across the inductor during the second switch conduction interval is established by the clamp voltage and the duty cycle, and varies with duty cycle. The amplitude of the signal at the junction of the two switches varies with duty cycle variations in such a manner as to maintain the signal of one polarity across the load at a constant amplitude.

Title: Machine for manufacturing structural elements by braiding threads, and structural elements manufactured on this machine.
IPC: D04C1/06
Filed: 1985-03-22
Abstract: Cores (a1-a4) pass through separate points in a plate (1) of the machine, over which plate thread-carrying spools (171-1724) are free to move. Two pairs of spools (i.e. four spools) are associated with each of the six possible pairs of the cores (a1-a4).

Filed: 1985-07-23
Abstract: PURPOSE:To enable the recombination of a backup roll by arranging an actuator for work roll control between a work roll and the project block which is provided on a backup roll chock. CONSTITUTION:Actuators 13, 15 controlling work rolls 1, 1' are arranged between the project block 18 which is provided on work roll chock 12, 14 and backup rolls 2, 2' respectively. A projection is provided respectively on the work roll 12, 14, which control the shift of the work rolls 1, 1' by engaging with the hook which is motioned by a hydraulic cylinder. The recombination of the backup rolls 2, 2' by the hook for recombination is thus enabled freely with this mechanism due to no projection being provided inside the window of a housing 9. Consequently the recombination of the backup rolls 2, 2' as well as the correct shape control of the work rolls 1, 1' can be performed.

Title: Motion damping apparatus
IPC: B63B21/50
Filed: 1985-10-11
Abstract: The present invention generally relates to devices and methods used to suppress the motion of an offshore structure due to wind, wave, seismic, and current forces. More specifically, the invention suppresses structural excitation due to secondary wave forces. The apparatus comprises a mechanical energy absorbing means and a submerged mass. The mechanical energy absorbing means may be a combination of linear or non-linear springs and dampers and is attached to the structure so the vibrating motion may be transferred to the motion damper. The proper weight or size of the damper and mechanical energy absorbing means is determined by first measuring the natural frequency of the structure and the mass of the structure then using those numbers in an equation to calculate the mass and spring constant for the desired apparatus.
