Abstract: A method for assembling onto a substrate through fluid transport. The microstructures being shaped blocks (19) self-align into recessed regions (55) located on a substrate (50) such that the microstructure becomes integral with the substrate. The improved method includes a step of transferring the shaped blocks into a fluid to create a slurry. Such slurry is then ppoured evenl y over the top surface (53) of a substrate having recessed regions thereon. The microstructure via the shape and fluid tumbles onto the sur face of the substrate, self-aligns, and engages into a recessed region.

Abstract: A fiber preform is made solely from a deformable base fiber structure that is initially in the form of a plane plate constituted by superposed two-dimensional fiber plies bonded together by needling. Cuts and/or splits are formed in the base fiber structure, and the preform is made from the cut and/or split base fiber structure by making use of its ability to be deformed. The structural part is obtained by densifying the preform using a material that constitutes a composite material matrix. It is possible to use a single fiber structure plate which is deformed with the help of splits or cuts so as to obtain the desired preform and in which continuity of the base fiber structure is preserved, or else a plurality of base fiber structure plates can be used which are assembled together by mutual interfitting via the splits or outs, by deforming at least: one of the plates.

Abstract: The movable manufacturing facility (100) brings standard size home building comprehensively within a controlled factory environment. The main structure of the movable manufacturing facility is sufficiently tall to allow assembly an d movement of standard size homes within. Multiple independent production line s (P1-P5) are established to each produce portions of the dwelling in the form  of subassemblies. Finishes, cabinets, appliances, roofs, paint, etc., are installed in the partially completed dwellings prior to houses leaving the production floor. The movable manufacturing facility allows a standard size home under construction to be advanced via a transport element (T) from one production line to the next until complete. The completed homes are subsequently transported on the transport element over a controlled access roadway to individual sites with pre-constructed foundations specifically designed to accept these standard size dwellings. The standard size house ca n be relocated from the transport element and placed directly onto the foundation. High capacity hoisting, such as clear span bridge cranes (H1-H3) , are the key to material handling and transportation on the production lines in the movable manufacturing facility. A drive through alley large enough to accommodate semi-trucks with loaded trailers may be located within the main structure of the movable manufacturing facility.

Abstract: Le système de commande de moteur faisant l'objet de cette invention permet de réduire le bruit tout en réduisant les besoins en puissance et en fournissant un couple suffisant. Un mode d'entraînement à monophase passante, modifié en progression par micropas entre les positions à monophase passante, est utilisé pour accélérer le moteur d'une façon non linéaire jusqu'à une vitesse maximale. Les modes d'entraînement par micropas possèdent une période constante et on augmente la vitesse des pas du moteur en réduisant le nombre des micropas dans des pas successifs du moteur. Une forme d'onde de pas entiers modifiée maintient le moteur à la vitesse maximale, pendant laquelle le courant alimentant l'un des enroulements du moteur pas-à-pas change de polarité à l'intérieur d'un même pas du moteur, tandis que l'autre reste approximativement constant, assurant ainsi une plus grande douceur d'entraînement et un bruit réduit. La polarité change en fonction de l'inductance et de la tension en courant constant du moteur. Une forme d'onde à monophase passante, modifiée de façon à inclure des micropas entre des positions à monophase passante, entraîne par la suite une décélération du moteur d'une façon non linéaire, et le moteur s'arrête dans une position encliquetée, jusqu'à ce qu'une autre forme d'onde des pas soit fournie au moteur.

Title: Method and apparatus for modifications made to a video signal to inhibit the making of acceptable videotape recordings
Inventor: RYAN JOHN O
IPC: H04N5/91
Filed: 1997-05-07
Granted: 2001-08-07
Abstract: A video signal is modified so that a television/receiver still produces a normal picture from the modified signal, whereas videotape recording of this signal produces generally unacceptable pictures. Videotape recorders have an automatic gain control circuit (Fig. 2) which measures the sync pulse level in a video signal and develops a gain control correction signal for keeping the video applied to an FM modulator in the videotape recording system at a fixed predetermined level. A portion of the back porch intervals following the trailing edges of a substantial number of sync pulses are significantly raised and lowered to improve the playability of the original signal without reducing the effectiveness of the copy protection of the copied signal. This is achieved most simply by adding pulses to selected lines of the video signal during the back porch interval, which pulses significantly raise or lower the voltage amplitude during the blanking interval so to provide a signal where the average value is approximately equal to the blanking interval. The sync level and the sync duration on the selected lines are also reduced to enhance the effectiveness of the process.

Abstract: A digital broadcast receiver is provided which can reliably perform a seek operation for an ensemble. When a NULL symbol is detected by a NULL detector 20 while a front end 2 sequentially tunes in frequencies of a plurality of ensembles, a system controller 37A checks whether the NULL detector 20 detects a transmission mode permitted for the band of the ensemble to be presently sought. If detected, the seek operation is terminated, and the automatic frequency adjusting system including a frequency error detector 33A, integrator 34, D/A converter 35, reference oscillator 13, and PLL circuits 7, 12, 17 adjusts a frequency. If the NULL detector 20 does not detect a transmission mode permitted for the band of the ensemble to be presently sought, the seek operation continues.

Abstract: This invention relates to apparatus used in supporting safety rails and discloses a system in which a safety rail post support and security device is used in pairs or greater multiples to hold pieces of as a safety rail at the edge of an elevated surface and is speedily attached to or detached from the three commonly found roof edge structures, that is, roofs that are flat right up to the edge, roofs that have a very low ledge or flashing around the perimeter, and roofs that have a parapet along the edge. Previous systems rely on cantilever weights positioned well in from the edge of the roof, interfering with the work to be done there. The post support and security device has a junction piece comprising four intersecting extruded stabilizer bars perpendicular to each other in one plane and a fifth bar protruding from that plane at ninety degrees. An upright post fits into one of the bars after the junction piece is bolted to a roof or to a wall abutting the edge of a roof, or is clamped to a parapet. The upright post has two brackets, each adapted to hold one or two 10 foot 2 by 4 inch lumber rails. The adaptable safety rail system of the present invention for flat roofs and parapets exceeds typical safety barrier standards for workers on such roofs.

Title: Digital signal framing systems and methods
Inventor: COADY ALAN CHARLES
IPC: H04J3/06
Filed: 1999-07-27
Granted: 2005-01-04
Abstract: A method and apparatus for detecting framing alignment sequence within a received bit stream. A stream state memory is assigned for each possible location of the framing alignment sequence. Bits of a particular stream are loaded into the respective stream state memory. If the bits do not match an acceptable subsequence of the framing alignment sequence then the stream is eliminated from consideration by writing an exile state to the respective stream state memory. Then subsequently received bits are used to transition either to the next state if the next bit is a correct bit in the framing alignment sequence, or to the exile state if the bit is not the correct bit. After all of the streams have been exiled but one, the remaining stream may contain the framing alignment sequence. However, it may be that a certain number of correctly received bits are required to declare in-frame with sufficient certainty in which case incoming bits will continue to be processed until this is satisfied. Examples are given relating to DS1 superframe and extended superframe framing alignment sequences.
