Abstract:
A hinge assembly (2100) includes a hinge body (2102) made of two hinge body halves (900). Each hinge body half is identical so that only one part need be manufactured, and two of them used to form the hinge body. Each hinge body half has a first leg (902) that is longer than a second leg (904). The first leg has a retaining lip (912) at the end which forms a retaining feature. Each leg of the hinge body defines an axis of rotation for the body elements (104, 106). A portion (1508) of a flexible circuit board (1506) is captured between the hinge body halves so as to electrically interconnect circuitry placed in each body element. A detent mechanism is provided to hold the body element in preselected positions with respect to each other, and includes a spring (2106), a cam (2108) and a cap (2110) having cam follower features (2118). The cam is held in place with respect to the body element housing, while the cap is fixed in position with respect to the hinge body. To stabilize the rotation of the body elements, a hook (2404) retains a collar edge (2402) upon rotation of the respective body element.

Abstract:
Novel nonionic gemini surfactants are extremely effective emulsifiers for oil-in-water emulsions that provide improved detergency at even low concentration levels. The surfactants are characterized by the formula: wherein R1 is independently H or a C1 to C22 alkyl, R2 is H or C1 to C22 alkyl and R3 is D1—R4—D1 or R4—D1—R4 wherein R4 is independently a C1-C10 alkyl group, —C(O)—, —R5[O(EO)a(PO)b]—, —O—R5—O—, or aryl, e.g. phenyl, and D1 is independently —O—, —S—, —S—S—, —SO2—, —C(O)—, a polyether group [—O(EO)a(PO)b—], an amide group [—C(O)N(R6)—], an amino group [—N(R6)—], —O—R5—O—, or aryl. (EO)a(PO)b is a polyether group and Z is a C1-C4 alkyl, or an alkylaryl or hydrogen wherein EO represents ethyleneoxy radicals, PO represents propyleneoxy radicals, a and b are numbers of from 0 to 100, a is preferably from about 0 to about 30 and b is preferably from about 0 to 10, wherein a plus b is at least one, and the EO and PO alkyl or alkylaryl.

Abstract:
An intelligent current lead device, its design, fabrication, and methods of operation are described in this disclosure. The intelligent current lead device described in this disclosure electrically and thermally connects and disconnects one or more power sources or loads operating at one temperature reservoir with one or more machines or devices operating at either the same or a different temperature reservoir. The intelligent current lead can operate in either an active mode or passive mode. The intelligent current lead device may incorporate the use of multiple types of diagnostic sensors and instrumentation, which can be monitored, interpreted, and analyzed. The program logic of the intelligent current lead may be used to interpret the data obtained from the diagnostic sensors and instrumentation in order to adjust/actuate/switch the current lead so as to optimize its configuration to respond to requirements of an electrical load that changes with time. There are many applications that the intelligent current lead can be used in conjunction with including but not limited to: superconducting magnets, transformers, power cables, energy storage, motors, generators, fault current limiters, circuit breakers, fusion magnets, accelerator magnets, MRI magnets, NMR magnets, induction heaters, magnetic separators, among other applications.

Abstract:
A method of forming a poly(arylene ether)-containing solid concentrate is described. The method includes blending a poly(arylene ether), a thermosetting resin, and a compatibilizing agent in the presence of a solvent to form a homogeneous solution, and removing the solvent to yield the solid concentrate. The solid concentrate is useful for preparing curable conditions.
Abstract:
The invention concerns a collapsible projection assembly (112) and a method (600) for operating same. The collapsible projection assembly can include a rotatable arm (116) having at least one pivot point (118), a projector (120) that can project an image (122) onto a surface (114), a first sensor (124) that can detect the location of an input device (128) in relation to the image and a second sensor (126) that can detect when the input device pierces a plane (130) above the image. The rotatable arm can be movable from a non-operational position to an operational position such that a predetermined spatial relationship between the projector, the first sensor and the second senor can be at least substantially maintained when the rotatable arm reaches the operational position.
