Patent ES-353276-A1 (ES)
Title: Method for operating fluorescent tubes
IPC: H05B41/46
Filed: 1968-04-27
Abstract: Fluorescent tube is connected to two supplies of different frequencies in such a way that lighting is not interrupted when one supply fails. The tube 1 is supplied from the mains 4 through a choke 2 and is also connected to a battery supply 8 by way of an inverter 12. The battery is charged from the mains through a transformer 5, bridge 6 and diode 7. During mains operation, an electronic switch 13 on the inverter is held open by a voltage appearing at the terminal 14 of the bridge 6, but when the mains voltage falls below a preset value, the switch 13 closes so that the tube 1 is supplied from the battery 8. The tube may operate with both sources connected simultaneously if the mains voltage is low but not zero. Restoration of the mains causes the switch 13 to open, disconnecting the battery supply. A resonant LC circuit 9, 10 enables the tube to be ignited when only the battery supply is available, since a high voltage will be generated across the inductor 10 when the inverter is switched on. The circuit components may be so chosen that the tube output is lower on battery operation than on mains supply.

Title: Control circuit for electrodeposition system using silicon controlling rectifiers
IPC: C25D21/12
Filed: 1968-06-25
Abstract: An electro-deposition apparatus is provided with means whereby the plating current is controlled initially at one constant value and subsequently at a second constant value and the increase in current from the first value to the second value having a constant rate. The current supply to a pair of plating electrodes is controlled by varying the voltage output of a silicon controlled rectifier device 22, the control being effected by way of a differential amplifier 23 comprising saturable reactors, whereby the phase of the gate signals for the thyristors is altered in accordance with the error signal between the thyristor output voltage and the desired output voltage represented by an input signal E. The signal E is varied to produce the desired plating current pattern, a relay contact 14 first being set, manually or otherwise, in the position 15 16 when the initial constant value of the plating current is adjusted by variable resistor 13. After a given time period the contact 14 is moved to position 16, 18 when a D.C. amplifier 10 together with a capacitor 11 becomes an integrating amplifier whereupon the plating current is caused to increase linearly, at a rate set by variable resistor 20, until it reaches the second constant value adjusted by a potentiometer 21, the diode 17 forming a clamp to prevent any increase in the signal E when it reaches a value set by the potentiometer.

IPC: H04N3/18
Filed: 1969-11-18
Abstract: A circuit for obtaining a focus voltage that varies with the final anode voltage has a rectifier, a resistor, and a capacitor connected to a horizontal output transformer, which is specially designed to be resonant at the fifth harmonic. The series arrangement of the diode and the capacitor is connected between primary and secondary windings of the transformer, namely the anode of the diode is connected to a tap on the primary, and the remaining end of the capacitor is connected to that end of the secondary winding to which a capacitor for the fifth harmonic tuning is connected. The other capacitor end is connected to a tap on the primary. The latter tap comprises a much smaller number of turns than the first-mentioned tap to which the anode of he diode is connected. The required focusing voltage is derived from the resistor which is arranged between the cathode of the diode and ground.

Title: Gerotor motor with a stationary inner member and a rotating and orbiting outer member
IPC: F04C2/10
Filed: 1976-11-15
Abstract: A hydraulic motor includes an elongated output member which is supported for rotational movement about a central axis thereof. The output member is driven by a gerotor gearset which includes an outer member having internal teeth which mesh with external teeth on an inner member. The inner member is fixed against movement and the teeth on the inner and outer members define a series of expansible and contractable fluid pockets. The outer member orbits and rotates as a result of fluid being directed into certain of the fluid pockets to expand same and fluid is directed from contracting pockets. A tubular member drivingly connects the outer member and output member and transmits driving torque to the output member. The tubular member is connected in a 1:1 rotational driving relationship with the outer member and output member. The driving connection of the tubular member to the outer member and output member is such that the tubular member can rock relative to these members so that its motion describes a cone as it follows the orbital motion of the outer member and transmits rotary motion to the output member.

Title: Fluid operated seismic generator
IPC: G01V1/133
Filed: 1978-06-05
Abstract: In the field of seismic exploration, compressed-air guns may be used as sound sources. Known air guns employed complex valving and were wasteful of compressed air. The air gun sound source of this invention is of simple construction and is economical of compressed air. The gun (10) consists of an elongated housing (34) that has at least one radially-positioned exhaust port. The housing is charged with a volume of compressed air. A hollow cylindrical actuator (60) is mounted inside the housing and may be hydraulically or pneumatically driven within the housing in longitudinal strokes. The actuator has at least one radially positioned aperture (88) alignable with the exhaust port. A valve or sealing pad (96) is mounted in each aperture. An orifice (104) is cut into each pad. At one end of an actuator stroke, the valve blocks the exhaust port in the housing. When the shuttle is driven from one end of the housing to the other, as the valve orifice passes by the exhaust port, the exhaust port is opened momentariliy to allow the explosive escape of some of the compressed air in the gun. As the actuator completes its stroke to the other end of the housing, the exhaust port is again blocked.
