Patent ES-466129-A1 (ES)
Title: Method for operating a nuclear reactor to accommodate load follow while maintaining a substantially constant axial power distribution
IPC: G21D3/00
Filed: 1978-01-18
Abstract: This invention provides a method of operating a nuclear reactor having a negative reactivity moderator temperature coefficient with the object of maintaining a uniform and symmetric Xenon distribution above and below substantially the center of the core over a substantial axial length of the core during normal reactor operation including load follow. In one embodiment variations in the Xenon distribution are controlled by maintaining a substantially symmetric axial power distribution. The axial offset, which is employed as an indication of the axial power distribution, is maintained substantially equal to a target value, which is modified periodically to account for core burnup. A neutron absorbing element within the core coolant, or moderator, is employed to assist control of reactivity changes associated with changes in power, with the full-length control rods mainly employed to adjust variations in the axial power distribution while the part-length rodsremain completely withdrawn from the fuel region of the core. Rapid changes in reactivity are implemented, to accommodate corresponding changes in load, by a controlled reduction of the core coolant temperature. Thus, active core coolant temperature control is employed to control the reactivity of the core during load follow operation and effectively increase the spinning reserve capability of a power plant without altering the axial power distribution.

Patent ES-480185-A1 (ES)
Title: Adjustable conditioning plate for an impeller mower-conditioner
IPC: A01D43/10
Filed: 1979-05-03
Abstract: A tractor drawn and powered impeller mower-conditioner includes a transverse disk type cutter bar. An impeller rotor with free swinging flails is mounted above and slightly to the rear of the cutter bar with its axis of rotation parallel to the cutter bar. A transversely extending concave conditioning plate conforms closely to the forward upper quadrant of the rotor. A hood covers the rotor and conditioning plate and includes a forward portion which serves in part as safety shielding and a rearwardly extending crop deflecting and windrow forming portion. The rotor is disposed and rotated so that the flails intercept cut material delivered rearwardly by the cutter bar and carry it inside the hood up and over the rotor through the confined space or conditioning zone between the rotor flails and the conditioning plate and discharge it rearwardly. In its passage through the conditioning zone, the crop material is bruised or conditioned in such a way that its rate of drying in the window is accelerated. The conditioning plate is mounted so that radial clearance between it and the rotor flails can be adjusted to vary the degree of conditioning. Circumferential adjustment of the plate in relation to the rotor is also possible and particularly useful in setting the height above the ground of the leading or lower edge of the conditioning plate to suit the height of the crop being cut and conditioned.

Patent ES-8205070-A1 (ES)
Title: Improvements in and relating to testing coins.
IPC: G01R19/04
Filed: 1981-02-06
Abstract: A coin testing apparatus comprises transmitting and receiving coils (14) and (15) on opposite sides of a coin passageway (11). The transmitting coil is connected to high and low frequency oscillators (16) and (17). The output of the receiving coil is separated into the high and low frequency components by a high pass filter (21) and a band pass filter (22). In the high frequency channel the signal is amplitude controlled by a voltage controlled amplifier (23) rectified by a rectifier (24) and smoothed by a long time-constant circuit (26). The initial rise in level caused by a coin entering between the coils (14) and (15) is detected by an instantaneous level change comparator (32) which responds to the rate of change of signal level at the output of the long time-constant circuit (26) becoming equal to a preset threshold and causes a normally closed switch (27) to be opened. When the switch (27) is closed a comparator (31) compares the signal with a reference value from a source (30) and adjusts the gain of the amplifier (23) until the signal corresponds to the reference value. Upon the arrival of the coin the switch (27) is opened and a long time-constant circuit (28) causes the gain of the amplifier (23) to be maintained at the level before the arrival of the coin. A window comparator (33) compares the difference in voltage with voltage ranges for acceptable coins. A similar arrangement is provided in the low frequency channel but with two differences. The switch (27) in the low frequency channel is operated by the same instantaneous level comparator as is used for the high frequency channel and instead of a rectifier (24) a novel sample and hold technique is used for providing a d.c. signal from the output of the amplifier (23).

Patent ES-8406673-A1 (ES)
Title: Temperature compensated gas spring
IPC: F16F9/54
Filed: 1983-08-29
Abstract: A piston cylinder gas spring uses a combination of fluids to achieve a spring force which is more nearly constant with change in temperature than it would be if a single fluid were used. A primary pressure source is located within the casing (in chambers 26, 34) and acts against the piston 24 to urge the rod 30 out of the casing. A secondary pressure source is located within the casing (in chambers 28, 36) and acts against the piston to urge the rod into the casing. The primary pressure created by the primary pressure source is greater than the secondary pressure created by the secondary pressure source, and the percent change of the secondary pressure with temperature variation is greater than the percent change of the primary pressure with the same temperature variation. The primary source is nitrogen. The secondary source is a two phase liquid/vapour system e.g. acetylene, freon, ammonia, hydrogen bromide, sulphur hexafluoride.
