Title: Series compensator inserting real and reactive impedance into electric power system for damping power oscillations.
Inventor: GYUGYI LASZLO
IPC: G05F1/70
Filed: 1995-12-14
Abstract: A series compensator (11) for damping power oscillations in an electric power transmission system (1) includes a switching power converter (13) which injects a voltage into the transmission line (5) having a phase angle relative to transmission line current which is controlled to provide reactive compensation and to inject virtual real impedance into the line. The switching power converter (13) is a dc to ac converter which is capable of injecting virtual real impedance into the transmission line by virtue of the fact that it has a power exchange device (27) connected to its dc terminals (29). Where the power exchange device (27') is a resistor (37), the switching power converter (13) is capable of absorbing real power during surges in power on the line (5). Alternatively, the power exchange device (27) is a storage device (31) such as a battery bank or a super conducting magnet, in which case the switching power converter (13) can provide both virtual positive and negative real impedance.

Title: Creped nonwoven laminate loop fastening material for mechanical fastening systems.
Inventor: JACKSON WANDA WALTON
IPC: B29C59/04
Filed: 1998-05-13
Abstract: The creped nonwoven laminate loop material (10) of the present invention includes a creped nonwoven layer (12) attached to a support layer (14). The creped nonwoven layer (12) may be, for example, a spunbond nonwoven web or a staple fiber bonded carded web. The support layer (14) may be formed of any material that can be suitably attached or bonded to the creped nonwoven layer, including a foam, a plastic film or another nonwoven web. The exposed, top surface of the creped nonwoven layer includes raised "loop" areas (16) having low fiber density and high z-directional fiber orientation that are designed to receive and engage the hook elements projecting from a hook material. The raised areas (16) of the creped nonwoven layer are separated by non-raised areas having relatively higher fiber density and relatively lower z-directional fiber orientation when compared to the fiber density and z-directional fiber orientation of the raised areas. The primary areas of bonding or attachment of the bottom surface of the nonwoven layer to the top surface of the underlying support layer are the non-raised areas (20); in addition, some secondary bonding of the nonwoven layer to the support layer outside of the non-raised area may exist. The support layer (14) provides structural integrity for the creped nonwoven laminate material and dimensionally stabilizes the creped nonwoven layer. The creped structure of the nonwoven layer further provides resistance against compression of the fibers forming the hook receiving loop material during use, thereby facilitating entry and engagement of hook elements projecting from the hook material. The creped nonwoven loop laminate (10) of this invention can be employed as the loop material of a hook and loop fastening system, such as used on disposable personal care absorbent articles.

Filed: 2021-07-30
Abstract: The present disclosure relates to a method for preparing and applying an anti—lodging conditionerfor food crops. The conditioner principally includes a plant growth regulator, a B—group vitamin, a trace element fertilizer, and water. The anti—lodging conditioner for food crops is prepared bythe steps of: dissolving the trace element fertilizer in water until completely dissolved, forming an aqueous trace element fertilizer solution; mixing a 70% aqueous choline chloride solution with the aqueous trace element fertilizer solution and an aqueous ethephon solution successively, and adjusting pH to 1.5-3.0. Application time is from the day of foliar age remainder of 1 to the flowering stage. The present disclosure solves a defect that decreased yield and quality, accurate application time, and lodging resistance are in contradiction with a yield increase. The present disclosure lowers the center of gravity of gramineous crops, prolongs the functional period of functional leaves in the later stage and increases photosynthetic efficiency thereof, and enhances root activity of crops in the later stage, substantially improving later lodging resistance of the crops, and simplifying the application technology; the present disclosure sets forth that operation costs are reduced at the initial heading stage, i.e., breaking stage, without increasing operations of farmers.

Patent NL-7610819-A (NL)
IPC: G11C29/02
Filed: 1976-09-30
Abstract: A read/write memory of n stages, periodically addressed in a recurrent scanning cycle of n time slots in which binary words are written in and read out from respective stages, is connected to a data-handling network by way of a writing multiple and a reading multiple each traversing a respective selective inverter, i.e., an upstream inverter in the writing multiple and a downstream inverter in the reading multiple. The two inverters are controlled by a generator of pseudo-random binary signals, unrelated to those processed in the data-handling network, having an operating cycle coextensive with a scanning cycle. Depending on the character of the control signals issuing from this pseudo-random generator during each cycle, the two selective inverters pass the bits of their incoming words either in their original or in a complemented form; with words written in a memory stage in one cycle read out in the immediately following cycle, the control signals delivered to the two inverters are identical but staggered by one cycle so that the words appearing in the output of the downstream inverter match those fed into the upstream inverter in the preceding cycle when the memory operates properly. Under certain circumstances, when a memory stage is addressed out of turn so that loading and reading of its contents occur successively in the same cycle, the staggering of the two control signals is canceled. Malfunctions of the memory are detected by parity checks carried out on the words traveling along the reading multiple to the downstream inverter; an alarm signal is emitted upon the occurrence of an error in the same bit position in two consecutive cycles.

A mechanism causes the fan to slide, dependent on motor speed, so that when running the cover frees the opening, and when switched off shuts it. Both fan and motor rotor can be fixed to a shaft, the rotor being thrust out from inside the stator when switched off. On switching on, magnetism pulls it back inside the stator and the cover frees the opening.
Patent NL-7706768-A (NL)
IPC: G06F11/00
Filed: 1977-06-20
Abstract: A memory array, having a plurality of intersecting rows and columns, stores digitized speech. Each row and column intersection consists of a binary storage cell for storing one bit of digitized speech. Incoming digitized speech is loaded into columns of the memory array in a plurality of repetitive loading sequences, each loading sequence including: reading out the bits stored in successive rows of binary storage cells, replacing in each successive row of bits, a predetermined one of the bits in the read out row with a successive one of the bits of the digitized speech and writing each read out row of bits including the replaced bit back into the row. Multibit binary grunts (digitized speech segments) stored in the array are read out therefrom by applying the bits of the grunts to time slots in frames on a time-division highway, each frame being of n bits duration and including one bit from each of n grunts stored in the array. A selected grunt is extracted from the highway by commencing a count of the bits on the highway with a first bit of the selected grunt and by extracting the first bit and every nth bit thereafter. Memory malfunction is indicated when the number of rows in the array containing parity errors exceeds a predetermined threshold number.
