Abstract: A method of forming a net shape preform for a high performance ballistic helmet includes preparing one or more full prepreg plies, preparing one or more filler prepreg plies, wherein a shape and orientation of one filler prepreg ply of the one or more filler prepreg plies is different from a shape and orientation of another filler prepreg ply of the one or more filler prepreg plies, layering the one or more full prepreg plies with one or more filler prepreg plies to form a ply stack and deforming a portion of the ply stack while constraining the ply stack by applying in-plane tensional force to the ply stack to form the net-shape preform.

Abstract: A collapsible containment apparatus (36) with a first hub (21), a second hub (22), a plurality of articulated arms (23, 25) coupled to the first hub (21), a plurality of support arms (24) coupled to both the second hub (22) and the articulated arms (23), and a flexible canopy (73) carried by the articulated arms (23). The apparatus (36) is collapsed by relative movement of the two hubs (21, 22) away from one another, and deployed by relative movement of the hubs (21, 22) toward one another. When the apparatus (36) is deployed the canopy (73) creates a closed interior environment, which may be sterile.

Abstract: The present invention relates to a compound of the general formula: wherein R1 is a 4-pyrimidinyl ring substituted at the 6-position by halo, hydroxy, 2-cyanophenoxy, 2,6-difluorophenoxy, 2-nitrophenoxy or 2-thiocarboxamidophenoxy and wherein R2 is any group which can be transesterified to form a methyl ester. The present invention is also directed to a process of preparing said compound.

Abstract: A system and method for collecting responses to assessment or survey items utilizes an input device to store individual responses to items of an assessment or a survey. The input device transmits the individual responses to a receiving unit for storage and analysis. The responses can be transmitted immediately upon completion of an assessment or survey item, at predetermined times during the collection of responses, after a predetermined period of user inactivity or upon completion of a predetermined group of assessment or survey items. The input device can also store a collection file containing all the responses and transmit the collection file after completion of the assessment or survey. The system and method can also utilize a locating device to determine an initial location of an input device and to monitor the current location of the input device during completion of the assessment or survey to detect and deter cheating.

Abstract: A process for the preparation of a compound of the general formula (I): wherein R1 is a 4-pyrimidinyl ring substituted at the 6-position by halo, hydroxy, 2-cyanophenoxy, 2,6-difluorophenoxy, 2-nitrophenoxy or 2-thiocarboxamidophenoxy and R2 is any group which can be transesterified to form a methyl ester, which comprises treating a compound of general formula (II): wherein R1 and R2 have the meanings given above, with a formylating agent and subsequently treating the formylated product with a methylating agent

Abstract: A device is described for testing the force to shear a deposit of solder or gold from a substrate, these deposits having a diameter in the range 50-100 &mgr;m and being for the bonding of electrical conductors. A shear tool has a semi-cylindrical cavity which closely approximates to the mean diameter of a range of substrates. This tool is adapted to re-shape substrates for a better fit, re-shaping occurring over 30% or less of the circumference of a deposit, and to a depth of 10% or less of the diameter of the substrate.

Abstract: Apparatus for testing electrical wire bonds of semiconductor devices includes two unequal length cantilever arms (14a, 14b) on a baseplate (11) and a test head (15) at the free end of the arms. The arrangement ensures substantially frictionless straight line movement of a test hook (32) on the text head over the range of deflection expected. A pneumatic or magnetic (21, 22) frictionaless damper is disclosed. The test hook (32) may be orientated by a stepper motor (35) of the test head.

Abstract: A test device for applying a tensile force to electrical bond sites of a semiconductor device includes jaws (21), adapted to closely engage the surface of the bond site, typically a solder ball (22), while an inner edge portion (23) of each jaw approaches the jaw axis. By closely confining the bond site, the clamping forces exerted can be increased without risk that the bond site will be crushed. In a preferred embodiment the jaws permit slight reshaping of the bond site to increase the area of engagement therewith.

Abstract: An apparatus and method for testing angled strand connections in a miniature electrical device includes a test tool movable simultaneously along two mutually perpendicular axes and perpendicular to the strand direction. The tool measures breaking force along one axis only, the breaking force in the direction of tool movement being calculated by reference to the angle of tool movement. The method gives rapid testing of successive strands with good operator view.

Abstract: Apparatus for testing electrical bonds of a semiconductor device includes a cantilever arm (14a) with a test head (16) mounted thereon. The test head (16) is biased by the arm (14a) against a base plate (11), but can be moved away from the base plate (11) by an air bearing (22) to ensure substantially frictionless initial positioning. Sensing means (32;34) for sensing contact with a semiconductor substrate are also disclosed.

Abstract: A flexible lance and drive system (10) extends through manhole (12) into blow down lane (14) of a pressurized water reactor (PWR) steam generator secondary side assembly (16). The system (10) includes a support rail (18) passing through the manhole (12) and along the blow down lane (14). A transporter (20) is suspended for locomotion along the support rail (18). A flexible lance (24) extends through the transporter (20) and can be driven by the transporter into tube bundle (26) to a greater or lesser extent as required to observe and/or clean sludge deposits (28) within the tube bundle (26). High pressure hoses (34), nitrogen purge line (36) and Fiber optics cable (32) is supported by a spacerless hosebar structure (38). The hosebar structure (38) is integrally formed from a flexible plastic material in a single piece.
