Title: Wet oxidation system
Inventor: LE THO-DIEN
IPC: B01F5/10
Filed: 1995-07-12
Abstract: An apparatus is provided for oxidizing an aqueous suspension of organic matter at elevated pressure. The apparatus has a reactor and an inlet for the aqueous suspension which is introduced to an upstream end of the reactor. A device for circulating the aqueous suspension through the reactor. An inlet for an oxygen containing gas introduced to the aqueous suspension.

Title: Process for the fermentative production of cephalosporin
Inventor: KRIJGSMAN JOHN
IPC: C12P35/00
Filed: 1998-04-22
Abstract: The present invention relates to a novel process for the preparation of cephalosporins having been deacylated at the 7-amino group, by fermentation of a cephalosporin producing microorganism in the presence of a side chain precursor, extraction of the N-substituted cephalosporin compound as present in the fermentation broth or fluid to an organic solvent, back extraction of the N-substituted cephalosporin compound to water, treatment of the aqueous phase with a dicarboxylate acylase and isolation of the crystalline cephalosporin compound according to formula (1) from the conversion solution, characterized in that the fermentation broth or fluid is incubated at acidic conditions and an elevated temperature prior to extraction of the N-substituted cephalosporin compound to an organic solvent. Further improvements of the process are obtained by washing the first organic solvent extract with acidified water and/or by extraction of the side chain to an organic solvent and/or by treating an aqueous cephalosporin solution produced at one or more stages in the process of the invention with carbon dioxide.

Title: Specialized heaps for creation of objects in object-oriented environments
Inventor: SOKOLOV STEPAN
IPC: G06F9/50
Filed: 2002-05-08
Granted: 2005-05-18
Abstract: The present invention pertains to techniques for creating and maintaining objects in object-oriented environments. The techniques are especially well suited for Java programming environments. In accordance with one aspect of the invention, specialized Java heaps are disclosed. In contrast to conventional heaps, the specialized Java heap is designated for storing Java objects with similar traits in the same memory portion. As such, objects with similar traits can be allocated and maintained in a designated memory portion. Another aspect of the invention provides methods for allocating objects in the heap memory. These methods can be used to create and associate objects with similar traits in a specialized heap. As will be appreciated, objects can be created and maintained more efficiently in this manner. As a result, the performance of virtual machines, especially those operating with relatively limited resources (e.g., embedded systems), is improved.

Title: Phase change memory materials, devices and methods
Inventor: HEWARK DANIEL WILLIAM
IPC: G11B7/258
Filed: 2005-12-20
Granted: 2008-05-28
Abstract: A new class of phase change materials has been discovered based on compounds of: Ga; lanthanide; and chalcogenide. This includes compounds of Ga, La, and S (GLS) as well as related compounds in which there is substitution of S with O, Se and/or Te. Moreover, La can be substituted with other lanthanide series elements. It has been demonstrated that this class of materials exhibit low energy switching. For example, the GLS material can provide an optical recording medium with erasability 3-5 dB greater than the erasability of GeSbTe (GST) material which is the standard material for phase change memories.

Title: Laminated body
Inventor: BERNSTEIN MELVILLE SYDNEY
IPC: B44C5/08
Filed: 1982-04-29
Granted: 1985-10-09
Abstract: A laminated body comprises a substrate, particularly a glass sheet, having at least one pre-printed polyester film bonded to a surface of said substrate. In a particular embodiment the utilisation of a pre-printed polyester film enables plain glass to be utilised instead of figured glass since the bonding of the pre-printed polyester film to the glass sheet ensures that the plain glass complies with safety glass requirements. The provision of printing on the polyester film enables various patterns or pictures to be applied to the glass sheet as well as masking any undesired marks which may occur when bonding the pre-printed polyester film to the glass sheet.

Title: Wheel for a toy vehicle
Inventor: ROSENWINKEL DONALD ALFRED
IPC: A63H17/267
Filed: 1986-01-23
Granted: 1989-10-18
Abstract: A toy vehicle wheel that changes from a generally cylindrical periphery with an initial diameter and axial width to a greater diameter periphery. The wheel has a hollow shell of rubber or some other flexible material and opposed sidewalls of the wheel are moveable relative to each other to compress the axial width and increase the diameter. Across a substantial portion of the initial axial width a number of slits extend so that the periphery is serrated when it is enlarged. In one form, an axial screw engages a sidewall to rotate the wheel in its initial quiescent condition along a relatively unobstructed surface, but, upon encountering an obstruction, will draw the one sidewall toward the other. Variations provide for containing the axial screw within the compressed wheel or permitting it to extend out of a sidewall. Other forms provide for movement of the sidewalls relative to each other with bayonet locking in a desired condition and for spring bias in one direction.

Title: TDMA ranging
Inventor: HEDDERLY DAVID LESLIE
IPC: H04J3/00
Filed: 1991-12-11
Granted: 1995-04-26
Abstract: In Multistation Demand Assigned Time Division Multiple Access Systems digital information is communicated from a head end to a population of oustations so that all the outstations receive the same stream of digital information and select their traffic from it. Traffic is only sent to and from an outstation when there is a demand for it. As the outstations are at random ranges from the head end it is necessary to know the time of travel for a burst of information so they arrive at the head end sequentially. The traffic dependent free time is consolidated and made available for ranging-in outstations.
