Title: Magneto-optical recording medium and method for producing same
Inventor: IKEDA ETSURO
IPC: G11B11/10
Filed: 1992-02-27
Abstract: In a magneto-optical recording medium having a substrate, a recording layer having at least a rare earth - transition metal alloy film formed on the substrate, and a dielectric layer formed on the recording layer, a depth of an area in the recording layer containing an element derived from the dielectric layer is set to 70 .ANG. or less from an interface between the recording layer and the dielectric layer in a depth-directional film structure analysis by Auger electron spectroscopy. Accordingly, mixing of impurities into the recording layer can be suppressed to thereby lower a recording magnetic field.

Title: Optimum write-back strategy for directory-based cache coherence protocols
Inventor: BAYLOR SANDRA J
IPC: G06F12/08
Filed: 1992-03-12
Abstract: A directory-based protocol is provided for maintaining data coherency in a multiprocessing (MP) system having a number of  processors  with  associated  write-back  caches,  a multistage  interconnection network  (MIN)  leading to  a shared memory, and a global directory associated with the main memory to keep track of state and control information of cache lines.  Upon a request by a requesting cache for a cache line which has been exclusively modified by a source cache,  two buffers  are  situated in the global directory to collectively intercept modified data words of the modified cache line during the write-back to memory. A modified word buffer is used to capture modified words within the modified cache line.  Moreover, a line buffer stores an old cache line transferred from the memory, during the write back operation.  Finally, the line buffer and the modified word buffer, together, provide the entire modified line to a requesting cache.

Title: Piezoelectric cell growth biosensing method and system
Inventor: EBERSOLE RICHARD C
IPC: G01N33/543
Filed: 1990-06-25
Abstract: The invention relates to a piezoelectric biosensor device and also to a method and a system utilizing a piezoelectric biosensor device for detecting metabolic growth requirements, antibiotic responses, and the specific bacterial products of microorganisms.  When a microorganism is grown in an appropriate nutrient medium containing a metabolite-responsive polymer, metabolic products of the organism acidify the medium and precipitate a polymer/metabolite complex which desposits or accumulates on the surface of a piezoelectric biosensor device. The mass change on the surface of the device resulting from this deposit produces a change in the resonant frequency of the piezoelectric biosensor device which can be used to determine the growth and type of microorganism.

Title: Process for producing fatty acid esters of lower alcohols
Inventor: WIMMER THEODOR
IPC: C07C69/24
Filed: 1991-06-28
Abstract: A B S T R A C T   The invention relates to a process for the   production of the fatty acid esters   of lower monovalent alcohols by transesterification    of fatty acid glycerides   in the presence of basic catalysts. The process according to the invention  is  characterized  in  that  the  transesterification  is carried outin the presence of  0.025  to 0.045  mols of an alkali or alkaline earth metal compound,  preferably   sodium  hydroxide,    potassium  hydroxide,   sodium or potassium alcoholate,   based on  100 g  of fatty  acid glyceride   and the subsequent purification  of the fatty acid esters  is effected by  the addition of  0.3 to  3.0 percent of water   by hydration and separation of the catalyst residues and other impurities.  In contrast to the known processes,   it is thus  possible  to  obtain  lower  alcohols  of  any  given  high  degrees  of transesterification  and high purity from untreated oils and fats  of natural origin with contents of up  to 20 percent of  fatty acids in the free state at  ambient temperature   and  atmospheric pressure  at minor alcohol excess by        means       of       the        simplest   equipment.

Title: Vehicle tracking system employing global positioning system (gps) satellites
Inventor: BROWN ALISON K
IPC: H04W64/00
Filed: 1992-04-22
Abstract: A tracking system employing global positioning system (GPS) satellites provides extremely accurate position, velocity, and time information for vehicles or any other animate or inanimate object within any mobile radio communication system or information system, including those operating in high rise urban areas. The tracking system includes a sensor mounted on each object, a communication link, a workstation, and a GPS reference receiver. The sensor operates autonomously following intialization by an external network management facility to sequence through the visible GPS satellites, making pseudo range and delta range or time difference and frequency difference measurements. No navigation functions are performed by the sensor, thereby permitting significant reductions in the cost thereof. The raw satellite measurements, with relevant timing and status information, are provided to the communication link to be relayed periodically back to the workstation. Differential corrections may also be provided at the workstation to increase the accuracy of the object location determination. In normal operation, three satellite measurements are required to compute the location of the object, but for a short time period a minimum of two satellite measurements are acceptable with time, altitude, and map aiding information being provided by the workstation.

Title: Pipe joint seal
Inventor: TEMPLE LOWELL D
IPC: F16L21/035
Filed: 1992-04-29
Abstract: ABSTRACT An improved sliding pipe joint seal for use in sealing an annular space created between a sealing surface of a spigot at an end of a length of pipe and a sealing surface of a bell shaped end of another length of pipe when the two pipes are connected end-to-end.  The pipe joint seal includes an annular body having an inner gripping surface and an outer tab.  The gripping surface is adapted to engage the sealing surface of the spigot to retain the seal thereon.  The body has a normally closed annular chamber storing a lubricant, such as a grease.  An annular slit in the body extends into the chamber forming a flap intermediate the slit and tab.  The slit is spread apart when the the bell shaped end engages the seal as the pipes are joined, thereby releasing the grease against the sealing surface of the bell shaped end as the seal slides over the remainder of the sealing surface of the bell shaped end.

Abstract: A mixture of material is transported by a vibrating conveyor (B), deposited thereon by belt conveyor (A), before an inlet (11) of a suction mouth (1). Suction mouth (1) is adjustable in all directions and by using the adjustable units (2) mounted on the suction duct (4), the height of the mouth (1) may be adjusted above the transported mixture of materials which is to be treated. The width of the opening (11) of suction mouth (1) is adjustable (20-26) to shape the mouth either symmetrically or asymmetrically. The suction power at the inlet (11) of the suction mouth (1) is regulated by adjusting its width combined with outside air supply using an air inlet valve (3) associated with suction duct (4) and adjustments of the capacity of exhaust fan (8). The exhausted air is fed to a cyclone (5) in which the materials which are sucked up and transported with the air have to be deposited. The behaviour and velocity of flow of the air entering cyclone (5) are adjustable by using the air inlet valve (3) and adjustment of fan capacity. The suction of fan (8) is connected at the outlet pipe (7) of the cyclone (5).
