Filed: 2005-11-23
Abstract: An aircraft stringer lay-up assembly 10 is provided comprising a first mandrel element 12 having a first mandrel material 48 with a first mandrel coefficient of thermal expansion (COE) 50. A composite ply assembly 40 is laid up onto the first mandrel element 12 to generate a primary lay-up surface 42. The composite ply assembly 40 comprises a first primary fold-over portion 44 folded onto to the first mandrel right end surface 32. A second primary fold over portion 46 folds over to the first mandrel left end surface 36. The first mandrel coefficient of thermal expansion (COE) 50 is adapted such that the first mandrel 48 is movable between a first mandrel normal condition and a first mandrel heated condition where the first mandrel right end surface 32 and the first mandrel left end surface 36 move away from each other. The first primary fold-over portion 44 and the secondary primary fold over portion 46 are thereby moved such that wrinkles are pulled out of said primary lay-up surface 42. Element 12 has upper and lower surfaces 26, 28, side surfaces 30, and first mandrel right and left ends 34, 38. Portions 44, 46 may be affixed to the ends 34, 38. Vacuum bag assembly (70) (figure 3 - not shown) presses ply assembly 40 against element 12 during curing. Rigidity reducing slots (18) (figure 4 - not shown) allow mandrel element 12 to conform to a contoured curing block 24. Second mandrel element 16 has a coefficient of thermal expansion equal to that of first mandrel.

Title: Anti-kickback devices for circular saws
Inventor: WILSON MIKE
IPC: B23D45/16
Filed: 2006-03-03
Abstract: A circular saw comprises a motor housing 12, handle 14, actuator button 16 and blade shroud 18 all mounted on slotted baseplate 26. Baseplate 26 cooperates with a ridge 22 of rail 20 in order to guide the linear movement of the saw in the direction of arrow A. Within the baseplate is a mechanism that allows movement of the saw in this direction only and substantially prevents motion in the opposite direction. This mechanism may comprise spring 38 biased brake blocks 34,36 which ride along an angled surface 40 of mount 32 which itself is received in a recess in the baseplate. There is a small amount of friction between blocks 34,36 and ridge 22 such that movement of the baseplate along arrow A causes compression of the spring and lateral movement of blocks 34,36 away from ridge 22. Conversely, any motion of the baseplate in the opposite direction causes blocks 34-36 to be jammed against the ridge 22, thus arresting that motion. In an alternative embodiment blocks 34,36 may be replaced by rollers. In a still further embodiment, the blocks are replaced by cam members which are rotationally biased by torsion springs into contact with ridge 22.

Title: Routing method for cryptographic networks
Inventor: AYYAGARI ARUN
IPC: H04L9/00
Filed: 2006-09-28
Abstract: In a routing method for implementing Quality of Service (QoS, 80 fig. 4) architecture on a cryptographic network, packet headers containing resource reservations are allowed to cross cryptographic boundaries (14, 16) to reach their destination nodes (eg. N1 to N3 or N5). In High Assurance Internet Protocol Encryptor (HAIPE) schemes, encrypted data packets (22) cannot be deciphered by the shared transit network nodes which handle signalling messages, thus interfering with QoS mechanisms which differentiate network services and allocate resources to ensure performance. Under the new scheme, QoS requests are placed in a packet header field relating to forwarding information before encryption, and then packets are monitored (Fig. 2) in order to establish a data flow path (Fig. 3) to a destination address via a node compatible with the QoS requirements. This exploits allowed exchange schemes (eg. DiffServ Code Point DCSP and Explicit Congestion Notification ECN) and provides QoS features between secured enclaves across a shared transit network without additional control signals.

Title: Real-time gate etch critical dimension control by oxygen monitoring
Inventor: GIBSON GERALD W JR
IPC: H01L21/00
Filed: 2004-09-21
Abstract: In a process for controlling an etching rate for plasma-etch trimming a photoresist during manufacture of a transistor gate, an etchant gas concentration, specifically the oxygen radical concentration, and an inert gas concentration are determined and the latter concentration is used to normalize the etchant gas concentration. The normalized value is compared with a predetermined desired etchant gas concentration and the flow of etchant gas into the processing chamber 50 is controlled in response. To minimize undesirable anisotropic chemical etching during the plasma etching, a passivating gas is introduced into the chamber, the concentration of which may be monitored. The passivating material, for example a fluorocarbon material is used to form a passivation layer on vertical surfaces of the photoresist pattern to prevent lateral etching.
