Title: Method and apparatus for forming fiber mixtures
IPC: D01G7/04
Filed: 1979-07-20
Abstract: A method of forming fiber mixtures from different kinds of fiber includes the step of removing the fiber in a plurality of passes from a plurality of stored fiber lots containing the different kinds of fiber. During each pass, fiber is removed from consecutive stored fiber lots in partial quantities that are small relative to the entire fiber quantities in the stored fiber lots. According to the method, prior to fiber removal in the first pass, the entire fiber quantity in each stored fiber lot is separately determined and from such entire fiber quantity there is determined, for each stored fiber lot, a partial quantity to be removed from each stored fiber lot during the first pass. Each partial quantity represents a proportion of the entire fiber quantity of the respective stored fiber lot. Thereafter, at least during the first pass, the determined partial quantity is removed from the respective stored fiber lot.

Patent ES-8307037-A1 (ES)
Title: Gas flow modulation apparatus for an exhaust silencer of an internal-combustion engine.
IPC: F01N1/02
Filed: 1982-10-07
Abstract: The muffler comprises a resonator (6) which communicates by way of an outlet orifice (14) with a chamber (5). A flexible valve member (16) regulates the section of the passage through this orifice in accordance with the rate of flow of the gas through the outlet of the resonator under the action, for example, of the pressure prevailing in the resonator. When the running speed of the engine decreases, the valve member reduces the section of the passage through the orifice (16) and modifies the acoustic attenuation in the resonator. The valve member may be controlled by other parameters of the flow of the exhaust gas inside the muffler.
Patent ES-8309053-A1 (ES)
Title: Digital television signal processing system
IPC: H04N9/64
Filed: 1982-11-02
Abstract: A system is provided for filtering and demodulating digital color mixture signals, wherein the signals are filtered to remove out-of-band noise prior to completion of the demodulation process. Interleaved digital chrominance signal samples are first demodulated by a signal related in frequency to the video subcarrier to obtain interleaved color mixture signal samples of different sampling phases at baseband frequencies. The interleaved color mixture signal samples are applied to a digital filter at a rate which is a multiple of the color subcarrier frequency. The weighting coefficients of the filter are selected to obtain a bandwidth which passes the color mixture signal while removing out of band noise. Since the input signal sequence to the digital filter contains interleaved color mixture signal samples, alternate stages of the filter shift register are tapped, so that the output sequence will comprise filtered and interleaved color mixture signal samples. An output sampling switch accomplishes phase demodulation of the output sequence by selecting samples at a reduced sampling rate in accordance with the Nyquist criterion of the color signals and produces either one or two output sequences of filtered and fully demodulated color mixture signals. Tapped shift register stages of the digital filter may be coupled to two different sets of weighting coefficients and signal combining stages. The filter outputs may thus exhibit unequal bandwidths for filtered color mixture signals, which are commensurate with the desired bandwidths of the filtered signals.

Patent ES-8404602-A1 (ES)
Title: Method of concentrating fresh fruits
IPC: A23B7/005
Filed: 1983-06-16
Abstract: A method of concentrating fruits which preserves the original coloration and freshness of flavor and retains the structural integrity of the fruit for subsequent preserving or canning operations. The fruit is first subjected to a high vacuum while adding only enough heat to maintain the fruit at a temperature below the boiling temperature of water at the maintained vacuum. This is continued until foaming caused by the release of air in the cells of the fruit either ceases or is at least commencing to be reduced. The fruit is then moved in a thin layer through a heated, rotating cylinder maintained at the same vacuum to cause the juices in the fruit cells to migrate to the surface of the fruit. As the cylinder rotates, the juices coat the walls of the cylinder. The cylinder is heated to a temperature above the boiling point of water at the maintained vacuum to boil off this coating. The speed of rotation and the temperature are so interrelated that at least a major portion of the inner wall of the cylinder is continuously wetted by the coating of juices and the fruit is not tumbled in the cylinder. The process is continued until the desired degree of concentration has been reached.

Title: Elevator system
IPC: B66B1/34
Filed: 1984-08-16
Abstract: An elevator system in which distance pulses are generated in response to travel of an elevator car, and used to update a car position counter. The difference between the car position count and a count representative of the location of the target floor is determined when the elevator car reaches a predetermined distance from the target floor, and this distance-to-go (DTG) count is used to provide a speed pattern for decelerating and landing the car at floor level. A zone of fixed length is provided on each side of each floor, and, when this zone is detected, the DTG count is compared with a count representative of this fixed length. If they differ within a predetermined tolerance, it is known that a proper landing will or can be made, and the DTG count is changed to the correct value at the instant the zone is detected. Door preopening may be enabled at this time. If the difference exceeds the predetermined tolerance, no corrective action is taken, and door preopening is not enabled. The amount of the difference may also be subjected to various checks for determining if the elevator car should be taken out of service, or allowed to continue to run.
