Abstract:
This invention concerns a composition comprising a blend of polyolefin with the reaction of a functionalized polyolefin and polyetheramine in which the polyetheramine is grafted into the functionalized polyolefin in a customary mixing apparatus. A process for producing the reaction product of functionalized polypropylene and polyetheramine by melting with polypropylene in a customary mixing apparatus is also disclosed. Blends of the present invention are advantageously useful to prepare paintable automotive body parts. This invention further includes dyeable polyolefin compositions containing the reaction product of functionalized polyolefin and polyetheramine. Dyeable polyolefin fibers, including polypropylene fibers, are disclosed, which may be made by melt spinning, and which may be employed to make woven and non-woven fabric.
Abstract:
A method of allocating a cache used by a processor of a computer system between instructions and data is disclosed. Program instructions are loaded in the processor for monitoring relative usage of the cache by each value class and selecting a desired ratio of cache usage by the classes from among a plurality of available ratios, and cache blocks within the cache are evicted using a cache-replacement mechanism which restricts replacement of an evicted cache to a particular one of the classes of values (instruction or data) based on the desired ratio of cache usage. A multi-bit facility may be provided to indicate how to confine a selected victim to certain cache blocks, and the program instructions select the desired ratio of cache usage by setting the multi-bit facility. The cache-replacement mechanism can be a modified least recently used replacement mechanism. Different instruction/data ratios thereby may be provided, such as 1:1, 1:2, and 2:1.

Abstract:
A bit-serial digital expandor includes a bit-serial dual scaler block (340), a bit-serial rectifier block (320), a bit-serial lowpass wave digital filter block (350), a bit-serial scaler with overflow detection block (360), a bit-serial multiplier block (380), and a bit-serial scaler and clipper block (395). This bit-serial expandor can be used in an AMPS cellular telephone receiver to produce a receiver having a lower silicon area, gate count, and current drain compared to equivalent parallel architecture receivers.
Abstract:
Insulating oil in electric power transmission devices such as a transformer is filtered for removal of accumulated water and carbon particles. The filter and circulation pump are usually located in a separate cabinet external to the transformer with circulation conduits connecting the filter, the pump and the transformer. To prevent or minimize environmental contamination by leaks or ruptures in the oil circulation conduits, oil flow within the pump suction conduit is monitored independently of oil pressure within the pump discharge conduit. A flow rate or discharge pressure below a predetermined minimum operates motor control relays to terminate the pump drive motor operation and transmit appropriate alarms. Additionally, an accumulation of oil in the dry sump volume of a pump and filter housing also activates motor terminating relays and transmits an alarm. Simultaneous with disconnection of the pump drive source, the pump suction conduit is closed by a normally closed solenoid valve positioned in the line near the power transmission device.
Abstract:
A method and apparatus for measuring Polarization Mode Dispersion (PMD) of a single mode optic fiber by providing a PMD measuring instrument with a light source. Light is transmitted serially through the optic fiber being tested and an artefact with a known, stable PMD value. The artefact biases the total PMD measured by the instrument away from zero. The PMD of the optic fiber may then be determined by data reduction of the total measured PMD. The method may also be used to calibrate a PMD instrument.

Abstract:
An automatic chemical analyzer utilizes reagents supplied in reagent bottles. The reagent bottles are labeled on their bottom surfaces with an identification label bearing a machine-readable identification code. The automatic chemical analyzer includes a reagent tray having a plurality of tray apertures therein which receive coded reagent bottles and which expose the bottom surface of each bottle for optical viewing of the machine-readable identification code. The analyzer further includes optical scanner means positioned below the reagent tray for reading the machine-readable identification code on the bottom surfaces of reagent bottles within the tray apertures. The tray apertures are selectively located over the optical scanner means so that the analyzer can identify the reagent bottle and the contents thereof.The identification label has a spaced pair of position reference dots defining and orienting a label area. A plurality of bit fields surround the position reference dots, their positions being defined by the position reference dots. Each bit field maps to a single bit of a multi-bit binary bottle identification code. Bit dots are printed in selected bit fields to define the binary value of each bit of the multi-bit binary identification code.
Abstract:
A liquid encapsulated high density integrated circuit package which serves as a complete computer basic system module having both logic and memory circuits in the same package. This unit takes advantage of improvements in the integrated circuit art to minimize the number of physical units required to provide the desired memory capacity while simultaneously maximizing density and thereby minimizing signal path length. Basically the package contains a plurality of stacked semiconductor wafers each of which provides either integrated memory or logic functions. Each semiconductor wafer is mounted on an insulated wafer carrier and is connected to stacking pins around the perimeter of the carrier via a series of radial interconnection which are flexible expansion leads disposed around the outer edge of the wafer. Each wafer is floatation mounted by attaching only its center to the carrier to minimize the stress effects of a thermal expansion mismatch between the wafer, the carrier, and the radial interconnections.The carrier on which the wafer is mounted is constructed to mechanically secure and support the wafer at its physical center, to provide electrical contact to the wafer substrate, to provide support of electrical stacking pins which connect with stacking pins on adjacent carriers, to provide support for the radial interconnection expansion leads extending between pads on the wafer and the stacking pins and to minimize the effects of thermal mismatch in the structure.A finned housing encloses the stacked wafers and carriers and is hermetically sealed to a header having feed through termination pin such that the package can contain a liquid coolant which aids in the transfer of heat between the wafers and the finned housing thus maximizing the dissipation of heat from the wafers.
