Title: Dual-alloy disk system.
Inventor: HYZAK JOHN M
IPC: B21K1/36
Filed: 1989-07-28
Abstract: Two pieces of metal are bonded together at a surface by placing the two pieces into contact at the surface and forging the two pieces in a die which causes substantial displacement of the metal originally at the surface in a direction parallel to and outwardly from the edges of the surface and into vents in the face of the die and within the die impressions. The strain and displacement fields are controlled by the die and vent geometry which is designed to concentrate the strain and displacement along the original bondline. In this way, up to 99.9 %+ of the defects which are potientially present at the original surface are efficiently displaced with moving metal away from the original contact between the two pieces of metal into sacrificial ribs that form in the vents and the remaining defects are subjected to significant strain. A portion of the displaced metal which contains many of the defects and which forms the sacrificial ribs is removed from the resulting bonded workpiece as the sacrificial ribs are removed from the workpiece. The result is a bond with superior properties and with a bond surface which can be located very precisely both in orientation and location (e.g., radial distance from the center of a disk). This system is particularly appropriate for forming dual-alloy high-pressure turbine disks for gas turbines in which an annular peripheral ring of a second superalloy is bonded to a central core of a first superalloy. The system is particularly effective if, prior to forging, surfaces to be bonded are closely shape-conforming, are very clean, and are diffusion-bonded using hot isostatic pressing while the surfaces are gas-free. The sacrificial ribs are formed by vents in the impressions of the forging dies. The vents are adjacent to the outer edges of the bond surface. The system may be accomplished by using one or more strikes in the same dies or same die geometry, or may include multiple strikes in which only one side of the bond is in proximity to a vent during each strike. Subsequent strikes would process the bondline resulting from the previous strikes, but with the rib removed. The die impressions would be so shaped that the resulting die cavity  would closely conform to the original workpiece shape, except for the vents, so that metal displacement and strain would be concentrated at the bondline.

Title: Vascular magnetic imaging method and agent.
Inventor: LEWIS JEROME M
IPC: C08J9/14
Filed: 1989-08-16
Abstract: The preparation and isolation of biodegradable superparamagnetic MR imaging contrast agents for the vascular compartment is described. These aggregates are comprised of individual biodegradable superparamagnetic metal oxide crystals which aggregates have an overall mean diameter less than about 4000 angstroms. The preferred vascular imaging contrast agent is comprised of aggregates of iron oxide crystals having an overall mean diameter less than about 500 angstroms. These contrast agents may be associated with a macromolecular species, which assist, among other things, in the preparation of these extremely small materials, and may be dispersed or dissolved in a physiologically acceptable medium. Preferred media also stabilize the materials against further aggregation even under harsh sterilization conditions. The autoclaved biodegradable superparamagnetic iron oxides of the invention are ideally suited for a pharmaceutical preparation and enjoy several advantages over prior intravascular imaging contrast media including low osmolality, low effective dose requirements, high relaxivities, long blood lifetimes, rapid biodegradability, and versatility with respect to a wide range of applicable MR data acquisition parameters.

Abstract: A central differential is provided for distributing an output torque of a transmission to front wheels and rear wheels of a vehicle. A fluid-operated restricting device is provided for restricting the differential operation of the central differential. The central differential is arranged to distribute a larger torque to the rear wheels than to the front wheels. A slip ratio of the rear wheels is calculated in dependency on rear-wheel speed and vehicle speed. The fluid-operated restricting device is operated in accordance with the slip ratio, in such a manner that the restricting magnitude increases with an increase of the slip ratio. When a driving condition is detected for fixing the distribution, the restricting magnitude is fixed to a predetermined value.

Title: Unitary enclosure and cover therefor
Inventor: DENNIS OTTO L
IPC: F16C19/38
Filed: 1990-10-29
Abstract: The interior of an antifriction bearing is isolated by an enclosure having a case (30) which fits into the outer race (2) of the bearing and primary and secondary lips (32, 34) which establish a barrier along a sealing surface (22) that is located beyond the inner race of the bearing. The primary lip (32) which is presented toward the interior of the bearing, does not actually contact the sealing surface, but has pumping cavities (66) which direct lubricant migrating along the sealing surface back toward the interior of the bearing. The secondary lip (34) projects away from the primary lip and actually contacts the sealing surface. The case, primary lip and sealing lip are all molded from a common polymer as an integral unit. Where the journal around which the bearing fits ends beyond one end of the bearing, a polymer cover (E) may be snapped over the enclosure at that end of the bearing to provide an extra measure of isolation.

Inventor: LANDMANN WOLF S
IPC: H04B14/02
Filed: 1990-12-12
Abstract: The digital interface divides a digital number (N₀) representing the sensor reading into a most significant part (MSB) and a least significant part (LSB). The most significant part is used to determine the pulse width of a sequence of pulses and the least significant part is used to selectively modify the pulses by increasing the pulse width of selected ones of the pulses. A lookup table (54) is used to evenly distribute the lengthened pulses throughout the pulse train. The resulting waveform has a DC component representative of the original digital number which is extracted by low pass filtering. The energy in the non-DC spectral components is appreciably attenuated as compared to the spectrum of a standard pulse width modulated waveform. This makes it possible to use a filter (28) with considerably higher cutoff frequency and with considerably improved response time for a given resolution.
