Abstract: An apparatus for ultrasonically inspecting a component comprises a first ultrasonic transducer for transmitting an ultrasonic signal into a component having rotational symmetry and a second ultrasonic transducer for detecting the reflected, or transmitted, ultrasonic signal. A motor and a turntable produce relative rotation between the rotationally symmetrical component and the first and second transducers. Motors, a carriage and tracks on a frame provide relative radial motion between the rotationally symmetrical component and the first and second transducers to scan the whole of a surface of the rotationally symmetrical component. An ultrasonic signal analyzer analyses the detected ultrasonic signal by monitoring for ultrasonic signals having an amplitude above a predetermined amplitude and not having rotational symmetry and a display provides an indication that any detected ultrasonic signals above the predetermined amplitude and not having rotational symmetry is a potential flaw in the component.

Abstract: A method and system is described for building a document using a configurable plug-in architecture. In one example, a configuration file containing information of building the document with one or more components is received. The one or more components execute to modify or manipulate the document. The document may further be passed from one component to another component, where each of the components performs a function on the document. The sequence of execution of the components, the type of function or activity executed by each of the components, and/or configuration data of the components may be provided by the configuration file. The document may further be output to a user or stored.

Abstract: Defects within structures formed by deposition processes can be relatively expensive, particularly as previously non-destructive testing was performed only once the component had been formed. By in-situ continuous or intermittent sequential non-destructive testing, early notice of defects can be provided. Such early notice may allow rejection of the part-formed component, correction of the errors causing the defect, or through an auto-correction process adjustment of the deposition devices or otherwise to improve component quality. Generally, deposition processes provide for provision of a layer of material which is consolidated in order to form an object component through use of a consolidation device. By providing a non-destructive testing device which either continuously inspects the layers of consolidated component or sequentially inspects the object component, it is possible as indicated to provide an early identification of defect problems within a formed object component.

Abstract: A metal terminal is provided for insertion into the installing hole of a circuit substrate. The terminal has a slit that allows the terminal to be elastically deformable in a radial direction. The inserted portion has a tapered part with a diameter decreasing gradually in the insertion direction. The maximum outer diameter portion of the tapered part makes a circumferential linear elastic contact with a contact region. When the tapered part is inserted into the hole, it gradually contracts elastically. This allows the terminal to have a low insertion resistance. Further, if the terminal becomes inclined with respect to the axis of the hole, the maximum outer diameter portion maintains a circumferential linear contact with the inner peripheral surface of the hole.

Abstract: A tarnish-resistant gold color alloy comprises 30-50 percent by weight gold; 20-50 percent copper; 5-15 percent silver; 2-20 percent zinc; 1.5-15 percent palladium; up to 4.0 percent by weight platinum; and up to 1.0 percent by weight rhenium. The atomic ratio of copper to silver, copper to zinc and copper to palladium are respectively, 6-8:1; 2-12:1; and 5-30:1 and the weight ratios are respectively, 3.5-4.7:1; 3.0-18:1; and 1.95-11.66:1. Dental restorations comprising castings of the alloy have color values on the Hunter scale of L=80-90; a=2.5-3.5; and b=14-18. The dental restorations exhibit tarnish-resistant values of DE.sub.1 less than 13 and DE.sub.10 less than 20.

Abstract: A meat dehydrator is disclosed and process utilizing same for the preparation of dehydrated meat comestibles. The meat dehydrator comprises a circular pan member and a circular grill member contacting said pan and supported above a bottom surface of the pan. A cylinder member which opens upward and downward and has upper and lower rims is mounted on bracket means of the grill to thereby define a cylindrical dehydrating chamber above the grill and spaced apart from the grill to provide an opening between the lower rim and the pan member to allow air passage therebetween. A circular lid cover is also disclosed movably mounted at the upper rim of the cylinder member to define a top of the cylindrical chamber disposed below. The lid cover includes means for mounting a heating element to extend from the lid into the cylindrical chamber to provide the heat source for the dehydration of meat.
