Patent ES-344417-A1 (ES)
Title: Electric coil assembly
IPC: H01F27/32
Filed: 1967-08-24
Abstract: The primary winding 5 of an electric coil assembly, for example for a mains transformer, has one end covered with a portion of an insulating tube 9 of e.g. soft silicon rubber and the secondary coil 7 has one end remote from the covered end of the primary covered similarly as at 10, the adjacent surfaces of primary and secondary being insulated from one another by insulation, and connections are made to the windings at the end of each winding not covered by insulation. The insulating portions 9 and 10 may be separate and the insulation 11 may be paper, or the insulation 9, 10 and 11 may be portions of one single tube. The coil former 1 is of synthetic resin, and the connections 13, 15 to the windings are led through slots 17, 19 in the flanges 2, 3 of the former. The insulating portions 9, 10 if separate pieces, may be preformed.
Patent ES-345846-A1 (ES)
Title: Digital System For Controlling A Seismic Transducer
IPC: G01V1/155
Filed: 1967-10-06
Abstract: To eliminate equipment-induced timing errors in a waveform control signal for a seismic vibrator the signal, comprising a sequence of digital " words ", is placed in a buffer store and successive words are then read out from the store at a precisely controlled rate for application to a digital-to-analogue (D/A) converter and thence to the vibrator. In the Fig. 3 embodiment the control signal is computer-generated or derived from an analogue waveform by an analogue-to-digital converter and comprises digital samples (of a frequency sweep signal) in the form of sequentially recorded words, each word being two sequential " characters " of seven " bits " each, on magnetic tape 112. The seven bits are read in parallel by head 114 and applied to OR gate 120 to provide one clock pulse per character for driving shift register 124. These clock pulses, taken from one output of the shift register, are fed also to phase comparator 106 to provide an error signal for phase-locking the playback speed of tape 112 to a precision oscillator 90. Sequential outputs on lines 150-168 of register 124 open respective gates 130-148 to steer successive characters from playback amplifier 126 to an N-word buffer store 190-200 (e.g. comprising bi-stable circuits). The words are read out from the store by opening gates 212- 220 sequentially with pulses provided by shift register 222 at a precise rate controlled by oscillator 90. The readout rate is thus unaffected by wow and flutter in the tape playback process. The words from gates 212-220 are reconstituted as an analogue signal by D/A converter 98 and applied directly, or via a radio link 254, to the vibrator 18. This analogue signal may also be used in subsequent signal processing (e.g. correlation) of the output of a geophone array. As soon as a particular word has been read out from store the associated storage element is reset by an output from reset shift register 238 so that the storage element is freed for storing a further word from tape 112. If tape or other speed errors are large or have a long term drift a large buffer store is required and the store may then comprise magnetic cores or may be a random-access store of sufficient capacity to store the total digital sweep signal (in which case the tape record 112 is unnecessary). Details of the application of the individual data bits to the gates 130-148 and store 190- 200 are given (Fig. 4, not shown).

Title: Counter flow-dual pressure vent section deaerating surface condenser
IPC: F28B9/10
Filed: 1971-07-28
Abstract: Various forms of surface condensers are disclosed each respectively with a dual pressure deaerating system for condensate using a true counter-flow tray stack section. The tray stack section is disposed within reheating chamber and below a vent condenser chamber through which non-condensible gases are withdrawn from the condenser. Both the reheating chamber and the vent condenser chamber are pressure-isolated by trap means from the associated condenser space. Thus, variations in condenser load are not reflected by pressure changes in the deaerating system and the efficiency of the deaerating system is maintained. Reheating steam introduced into the reheating chamber below the level of the tray stack, flows through the tray stack, counter to the direction of flow of condensate, and to the vent condenser chamber which is maintained at a relatively lower pressure by an ejector. The true counterflow of steam through the tray stack both reheats the condensate and accommodates the separation of non-condensible gases from the condensate. One or more of the tray stack trays is disclosed to be of a construction having serrations along both its upper and lower edges to establish a plurality of drop points for the condensate.

Title: Circuit for the line synchronization in a television receiver having a gated auxiliary control loop
IPC: H04N5/12
Filed: 1976-10-06
Abstract: A line synchronization circuit in a television receiver in which gate pulses are derived from the oscillatorsignal for keying-out the synchronizing signal, in which the gate pulses are positioned by means of a phase-control loop symmetrically with respect to an edge of a reference signal which is also derived from the oscillator signal.

The circuit also supplies a keying pulse for the color synchronization signal. Pulling-in can be accelerated in the case of narrow gate pulses by increasing the width thereof in case of non-coincidence of the gate and the line synchronizing pulses or by interrupting the supply thereof.
