Patent ES-462407-A1 (ES)
Title: Methods of and apparatus for delaying the commencement of braking in regulated transport drives
IPC: B66B1/44
Filed: 1977-09-16
Abstract: The braking command is triggered, particularly in a lift drive, in dependence on two guide curves (VS1, VS2) which correspond to two voltages (Usoll, Ucomp) and on a third voltage (UX). The first guide curve represents the start-up variation, that is to say the speed of travel as a function of time. The second guide curve is the nominal braking variation in the same type of representation. The said third voltage is obtained by integrating the difference between these two guide curves in that the voltages corresponding to the guide curves are supplied to the input of an integrating section and the third voltage appears as output voltage at the output of this section. The voltages corresponding to the guide curves and the said output voltage are supplied to a comparator. The output signal of the comparator is used as braking command. This braking command delays the initiation of the braking process to a time (t1) so that a maximum speed is reached at the switch-over point. In this manner, the so-called crawling distance can be kept to an optimum shortness.

Title: A control device
IPC: G05B11/18
Filed: 1979-08-31
Abstract: Two-point controllers (2, 3) are provided for a two compartment heating installation, one having a narrow switching hysteresis (3) and the other having a wide switching hysteresis (2).

Title: Method for heat treatment of clay and refractory ware.
IPC: C04B33/32
Filed: 1980-06-17
Abstract: In order to facilitate oxidation of oxidisable material (typically carbonaceous) contained in refractory or clay ware during the firing of the ware in a tunnel kiln (12), commercially pure oxygen is introduced through the lances (20, 22, 24, 26, 28 and 30) into the region of the kiln where such oxidation takes place. This oxygen is directed into channels (44, 38 and 46) between stacks of ware (37 and 34, 34 and 36, and 36 and 39) for the time being adjacent the lances and carried by kiln cars (40, 32 and 42). The ware is advanced through the kiln (12) on the kiln cars in the opposite direction to the direction (48) of air flow through the kiln. The oxygen from the lances penetrates the stacks and thereby enriches in oxygen the air contained between individual items of ware in the stacks. The oxygen is typically added to the kiln at regions whose temperature is in the range 750 to 850 DEG C, and the flow of air through the kiln chosen to depress the oxygen concentration of the kiln atmosphere in carbonaceous material present at 600 DEG C to the temperature range 750 to 850 DEG C.

Patent ES-8404588-A1 (ES)
Title: Phase-locked circuit loop having improved locking capabilities.
IPC: H03L7/10
Filed: 1983-05-18
Abstract: A phase-locked loop having improved off-frequency detection. A variable frequency output signal is to be precisely locked to the frequency and phase of an alternating input signal. This is accomplished by alternately utilizing two feedback loops. A reference signal, having a frequency approximately equal to the frequency of the input signal is input to an initialization feedback loop in which it is mixed with the output signal. The initialization loop produces a feedback signal for controlling a voltage controlled oscillator which generates the output signal. An off-frequency detector detects the frequency difference between the output signal and the reference signal. When this frequency difference decreases below a predetermined level, the off-frequency detector disables the initialization feedback loop and enables a primary feedback loop. In the primary feedback loop the phase of the output signal is compared to the phase of the input signal, and the difference signal controls the voltage controlled oscillator in such a manner that the phase of the output signal tracks the phase of the input signal. With the scheme, the initialization loop, which has a wide bandwidth, is used to control the voltage controlled oscillator over a wide range of frequencies of the output signal (i.e., the initialization loop has a broad capture range). When the frequency of the output signal has been brought within the capture range of the primary loop, operation is switched to the primary loop. The primary loop has a narrower bandwidth and therefore provides better noise rejection than the initialization loop.
