Abstract: A process is described which imparts exceptional antisoiling, anti-staining and repellent properties to carpets. The process makes use of a water-based exhaustion process wherein the water-based treating solution contains (1) glassy fluorochemical material, glassy hydrocarbon material, or combinations thereof; (2) a stainblocking material; (3) a polyvalent metal salt, acid, or combinations thereof; and (4) water. Subsequent to exhaustion, the wet treated carpet is heated, usually in a steaming step, rinsed, and dried in a dry heat oven.

Abstract: An automated inspection system particularly adapted for detection and discrimination of surface irregularities of specularly reflecting and other materials, such as are employed in laminate chip carriers and printed circuit boards, includes an area scan image sensor allowing illumination sources to surround an area of a surface being inspected. The illumination source preferably provides either or both bright field and dark field illumination of the surface; developing generally complementary images of surface irregularities. A self-registering rules-driven process for developing inspection masks reduces alignment operations and improves performance. Image enhancement and morphological operations to detect surface irregularities are performed by digital signal processing, preferably using a dedicated vision processor. Masks screen potential defects to critical mounting and bonding surfaces accurately without requiring alignment of data or reference images to acquired images.

Abstract: A heat recovery apparatus and method suitable for steam cycle electrical generating plants including at the exhaust of a steam turbine one or more heat transfer units for capturing the heat in steam, including the latent heat of vaporization of the steam. Heat is transferred from the steam to a working fluid in at least one heat transfer unit. The heat transfer unit may also include a cooling apparatus. Piping and valves establish communication of the working fluid between the heat transfer unit and the gas turbine generator. The working fluid is moved through the system by selectively isolating sections of the piping and adding or taking away heat from adjacent sections to create pressure differentials. Connecting adjacent sections results in the movement of the working fluid mass as a result of the pressure equalization.

Abstract: Low energy surfaces based on nanostructured films exhibit advancing and receding contact angles for liquids such that (1) the difference between the advancing and receding contact angles approaches zero and (2) the advancing and receding contact angles approach 180.degree.. The low energy surface of the present invention comprises a nanostructured film coated with an organized molecular assembly (OMA). Advantageously, the chemical and wetting characteristics of the surface can be altered by changing the functionality of the OMA end groups exposed to the environment in contact with the surface of the nanostructured film.

Abstract: A retainer is used in combination with two tubular flow connectors to prevent the inadvertent disconnection of I.V. tubing sets. The retainer includes at least one open collar having a flexible opening so as to be radially and securely attachable adjacent to an increased diameter portion on a tubing connector. A pair of parallel straps connects the collar with an axially pivotable joint so as to facilitates easy manipulation and engagement of the retainer.

Abstract: A rolling element bearing member designed for use in a preselected bearing operation, such as a gas turbine engine, which develops a predetermined operating hoop tensile stress in the member includes a hardened layer contiguous with a ductile core having a hardness less than 50 Rockwell C. For example, the hardened layer is a carburized layer of high hardness in the range of 58-66 Rockwell C. The hardened layer has improved resistance to crack initiation and propagation as a result of providing the layer with compressive residual stress in an amount greater than the predetermined operating hoop tensile stress, for example in the range of about 10-60 ksi to a depth up to about 0.06 inch. Such a member is made by providing a member of a metal alloy having the capability of developing such a hardened layer, and then processing the member to develop the layer in the amount of compression.

Abstract: The rotor that carries the target in a rotating anode x-ray tube is carried on a shaft that is journaled in axially spaced apart ball bearings. The outer and inner races of the bearings have curved grooves presented toward each other and there are a plurality of balls in the grooves. A preloaded spring is interposed between corresponding races of the bearings for applying oppositely directed axial forces to them. The grooves are so shaped and the clearance between the balls and groove surfaces is such that when the axial force is applied, one race shifts axially relative to the other in which case each ball has two points of contact, one point at which the ball contacts the surface of the groove in the outer race on one side of a plane transverse to the shaft axis and another point where the ball contacts the surface of the groove in the inner race on the other side of the plane.
