Abstract: Titanium is prenitrided by being heated in a nitrogen environment under conditions which give rise to the formation of a titanium-nitride surface layer on the titanium. Titanium thus prenitrided may be used in electrical components which are hermetically sealed using silicate glasses and standard glass sealing techniques. According to the method of the invention, alkali volatilization and formation of deleterious interfacial silicide are inhibited.

Abstract: A novel loading probe for fiber-matrix testing machines is made of diamond and has a truncated cone end for push-in and push-out tests of fibers in a fiber-matrix composite. The diameter of the probe body or shaft is greater than the diameter of the fiber to be pushed and the flat surface where the cone is truncated is at least one-half the diameter of the fiber. The included angle of the truncated cone is in the range of 55.degree. to 90.degree.. A useful compromise included angle is 70.degree..

Abstract: A signal amplitude distribution analyzer measures the amplitude probability density function of electrical signals, and in particular, the amplitude probability distribution of noise signals. Such measurements may be used to determine the "Gaussianicity" of noise signals, that is, a measurement of how closely the amplitude distribution of noise signals corresponds to theoretical values derived from the Gaussian probability distribution density function. This theoretical density function represents the relative percentage of time that a noise signal is at a given amplitude. The invention gives an approximation of this function by measuring the amount of time a noise signal is between a window of two adjustable voltage levels. This is accomplished by producing an output voltage proportional to the amount of time a noise signal amplitude falls within the window of values defined by the two adjustable voltage levels.

Abstract: This is a microstrip antenna which eliminates the cavity used typically in spiral and sinuous type antennas. A small spacer between the antenna element and ground plane replaces the cavity. This significantly reduces the depth of the antenna and permits antenna shapes which conform to a vehicle skin, such as an aircraft. The microstrip has demonstrated higher gain and efficiency than the cavity, but only over a limited bandwidth less than that of existing cavity backed antennas. To increase the bandwidth, the antenna has a variable thickness spacer with the thickness proportional to the distance from the center of the antenna. The employment of this variable spacer results in maintaining the high gain and efficiency of the microstrip antenna over a much larger bandwidth comparable to the existing cavity backed antennas.

Abstract: A coating is provided for an optical fiber that inhibits abrasion or scraing of the fiber's surface.

Abstract: A method for preparing asymmetric radial polymers wherein the different polymeric arms are contacted sequentially with a coupling agent. The method narrows the relative arm distribution of the several asymmetric radial polymers produced and significantly increases the amount of total product having the desired ratio of polymeric arms. Any coupling agent known in the prior art to be useful in the production of asymmetric radial polymers may be used in the method of this invention but coupling agents having from three to about twelve functional groups are most effective.

Abstract: A sleeve or collar for preventing the migration of infection along the length of an implanted lead. The sleeve or collar is given anti-microbial properties, as by embedding therein or coating with anti-microbial substance. At the time that a changeable portion of an implantable device is changed-out, e.g., when the pulse generator in a pacemaker system must be replaced due to battery depletion, the collar or sleeve in accordance with the present invention is affixed to the lead and slid as far distal along the lead as possible, in order to ensure that a barrier is established to prevent the migration of infection to the extreme distal end of the lead. In one embodiment of the invention, the collar or sleeve can serve the dual purposes of establishing an infection barrier and of facilitating the anchoring of the lead in place.
