Abstract: During the process of writing a grating, the fibre (F) is placed in a support (16) which has a surface cut-out such as a V-shaped groove (18). The side walls (20) of this groove (18) form an angle (a) of 60° with respect to the direction (X12) of propagation of the radiation arriving from the source (12). The aforesaid surfaces (20) have characteristics of high reflectivity with respect to the aforesaid radiation. Consequently, during the writing process, the core (1A) of the fibre (F) is subjected to the action of a plurality of radiation fronts converging on the core. The first radiation front corresponds to the radiation arriving from the source (12) and two other radiation fronts (B, C) are obtained from this radiation by the effect of the reflection from the walls (20) of the surface cut-out of the support (16). The preferred application is to the making of long-period gratings.

Title: Low impact gas spring
Inventor: STENQUIST SVEN
IPC: F16F9/49
Filed: 2000-12-22
Abstract: A gas spring having a main gas chamber, a secondary gas chamber and sealing surfaces which, during a portion of the stroke of the piston rod, define a gas tight seal between them to provide two separate gas chambers each providing a force acting on the piston rod in opposed directions to each other to reduce the net force on the piston rod. When the piston rod is near its fully extended position the sealing surfaces provide the gas tight seal and the net force on the piston rod is minimal and in the direction to move the piston rod to its fully extended position. Thus, until the cooperating surfaces are displaced to terminate the gas tight seal, only a slight force is required to initially move the piston rod from its fully extended position.  This greatly reduces the impulse or impact force imparted to a press ram upon initial actuation of the fully extended piston rod. A second seal assembly may also be provided which controls the rate at which the piston rod assembly returns to its fully extended position. After the gas tight seal is terminated, the gas spring functions generally as a conventional gas spring with a single gas pressure acting on the piston rod and biasing the piston rod towards its extended position against the force of the ram displacing it.

Abstract: A method and system for adaptive signal processing for an antenna array reduces the requisite computations for executing an adaptive algorithm that combines or digitally filters baseband receive signals. The system receives uplink electromagnetic signals from a phased array and uplink electromagnetic signals from a diversity array during the reception of a desired electromagnetic signal transmitted by a desired mobile station.      The uplink signals are converted into baseband signals for digital signal processing. The baseband signals are observable as a series of successive time slots. The system determines uplink coarse combining weights associated with the uplink baseband signals of the phased array and downlink coarse combining weights associated with the downlink baseband signals of the phased array. The baseband uplink signals are summed into as few as one resultant baseband signal during or after application of the coarse combining weights to the baseband uplink signals.      The system determines fine combining weights for one or more resultant baseband signals and the baseband uplink signals on a symbol-by-symbol basis, or on any durational basis less than a time slot, to combine the signals into a single enhanced baseband signal for symbol detection.

Title: Truck cab
Inventor: FITZSIMMONS RALPH B
IPC: B62D33/06
Filed: 2001-02-28
Abstract: Truck cabs are enclosures for housing the drive of the vehicle to help protect him/her from the elements and from injury in case of an accident. This invention, the round cab a design, as in a seen in a plan view, helps to protect the driver in case of accidents in a superior way. In cases of head on collisions vehicles will deflect off of the cab easier than in the conventional square front cab. In cases of rollovers the cab will roll or slide easier with fewer injuries to the driver. The round cab gives the driver a much better view of his surroundings, as there are not any blind corners. With the sleeper located in the middle of the cab, the driver will be less likely to injury if the vehicle is struck while the driver is stopped and resting. The doors to the cab open inward in case of an accident so that the driver may escape easier. To service the motor or change the front tires the cab lifts forward on hydraulic cylinders attached to the frame and cab. Access to instruments and accessories are all from inside the cab of the truck so that replacing parts or making repairs is a lot easier.

Abstract: An automatic firearm, and particularly, an externally-driven automatic firearm for use in conjunction with aircraft or armoured vehicles. The housing of the automatic firearm contains a rotatable cylindrical breech mechanism with a cavity for receiving a loaded shell and a chamber for containing the shell during firing. Slidably mounted within the cavity is a breech block for ramming the shell into the chamber and locking the shell in place during firing. The breech block has a cam on its outer surface that acts in cooperation with an elliptical slot on the interior wall of the housing that causes the breech block to move longitudinally backward and forward within the cavity as the breech mechanism rotates. The rotation of the breech mechanism is controlled by an external drive mechanism. With each rotation of the breech mechanism the breech block soft rams a loaded shell into the chamber and retracts to permit the spent easing to be ejected and to permit a new shell to be loaded. The drive mechanism halts the rotation of the breech mechanism during firing of a shell, which, because of the cooperation of the cam and the elliptical slot, fixes the breech block in place. The breech mechanism contains multiple chambers and cavities, as in a conventional revolver, allowing the firing rate of the automatic firearm to be increased.

Title: Mpeg flow identification for ip networks
Inventor: MATTHEWS KIM N
IPC: H04N7/24
Filed: 2001-04-26
Abstract: The payloads of IP packets are checked to actually determine if a packet contains MPEG-2 video rather than using predefined streams or priority levels that are assumed to contain such information as is done in the prior art. More specifically, the "sync" bytes of the MPEG-2 stream are searched for within the IP packet payload, and when a pattern indicative of the sync bytes is found the sync bytes are identified and the packet is determined to contain MPEG-2 video. The sync byte was defined in MPEG-2 for over- the-air broadcasting in order that a television receiver be able to synchronize the MPEG-2 transport stream packets. Note that the MPEG-2 video, e.g., the MPEG-2 transport stream packets, may or may not be incorporated within real time protocol (RTP) packets before being incorporated into the IP packets.

Abstract: A simulated tree comprises an armature including a trunk with nodes thereon from which are supported branches guyed together by shrouds to stiffen the trunk and maintain the branches in spaced relationship, with a net cover supported thereon. Vines are cultivated over the surface of the net cover, whereby a structure having a mature tree-like appearance can be grown in a relatively short period, and at much lower cost than transplanting mature trees. The profile of the armatures is easily varied by changing the position of the nodes and the length of the branches, and a wide variety of trees can be simulated using modular components. Such components are easily joined together without the use of tools, making it possible to ship the armatures in kit form, using common carriers, for assembly and erection at remote and difficultly accessible terrains.

Filed: 1999-02-11
Abstract: There is disclosed a prolonged release microsphere which can constantly release medicinal drugs, such as luteinizing hormone-releasing hormone analogues and encapsulate them at high content rates. It is prepared by dissolving a copolymer of lactide and gycolide in methylene chloride, dissolving a luteinizing hormone-releasing hormone analogue and a release-controlling material in a subsidiary solvent, combining the above two solutions with each other to produce an emulsion phase, dispersing the emulsion phase in a solution of polyvinyl alcohol in distilled water to give a single emulsion system, removing the combined solvent of the emulsion phase to generate a polymeric microsphere; freeze-drying the polymeric microsphere. The microsphere prepared has a much finer inner structure, by virtue of which the microsphere is secured in a constant release rate. The single emulsion system which simplifies the preparation, allows for the maintenance of a drug content of 10 % or more. The charged groups of the release-controlling materials associated with the polymers minimize the excess release of the oppositely charged drugs at an initial stage, playing an important role in keeping the release rate constant.
