Title: Apparatus for the gasification of liquids
Inventor: TODD JOHN JAMES
IPC: C02F3/20
Filed: 1992-05-01
Granted: 2004-01-20
Abstract: An apertured flexible membrane (10) extends over a domed support (11). A  central gas supply tube (50, 82) terminates in gas outlets (51) oriented to direct the gas to flow horizontally into the space (40) between the membrane and the support to inflate the membrane away from the support so that gas from the inflated space discharges through the apertures (60) as fine bubbles and such that when the gas supply ceases the membrane collapses back into area contact with the support to seal all the apertures. This reduces clogging. The aerator is useful in the aeration of sewage or waste water and in fish or eel farms.

Granted: 1996-11-26
Abstract: A hydraulically powered repetitive impact hammer has internal features for ensuring continued auto-matic repetitive operation under adverse conditions, and fluid cushioning of internal parts to prevent damage from abrupt metal-to-metal contact. The hammer head of the impact hammer has an internal poppet which automatically closes to enable the buildup of pressure in a compression chamber during reloading in preparation for the hammer head's next blow, and automatically opens to enable the pressure in the compression chamber to drive the hammer head to strike an impact tool. To prevent inadvertent stalling of the hammer during reloading if the impact tool is pressed forcibly into contact with the working face after striking a blow, the amplification ratio of the hammer head is made greater than the amplification ratio of the poppet. Fluid cushioning of the hammer head to prevent abrupt metal-to-metal contact with the frame of the hammer at the end of the driving stroke is pro-vided by a temporary fluid restriction which operates only when the hammer head is near the end of its driving stroke. Fluid cushioning of the poppet to prevent abrupt contact with the hammer head is provided by mating fluid cushioning surfaces formed on the hammer head and poppet, respectively, for enclosing fluid in a confined space and metering the escape of fluid from the confined space as the poppet approaches one or the other extremity of its range of movement in the hammer head.

Abstract: To inhibit, or at least sharply attenuate, fluorescence of a quartz-glass envelope (10) surrounding a light source (11), such as a halogen incandescent lamp, a high-pressure discharge lamp, or the like, when the quartz glass is subjected to ultraviolet (UV) radiation from the light source, and has been doped with a UV radiation absorbing material, typically a cerium, or cerium-titanium doping, the quartz-glass envelope is additionally doped with praseodymium or a praseodymium compound, such as praseodymium oxide or praseodymium aluminate. The pure praseodymium in the doping is, preferably, present in quantities of between about 0.008 and 1.25%, by weight, with reference to the undoped quartz glass.  Barium metaborate can also be used, preferably together with praseodymium to attenuate the fluorescence.  Preferably, the praseodymium is used as a combined doping with cerium, in form of a cerium-praseodymium aluminate, added to the starting material for the quartz glass, and before the quartz glass is fused from quartz sand or pulverized quartz crystal.

Abstract: A rewritable ROM file device.  A directory 101, a FAT 102, and a rewritable area 103, whose data may be rewritten, are together called a special area of the ROM file 100.  A buffer 200 is used to store only data of the special area.          An access controller 300 copies  the data stored in the special area to the buffer 200 before the special area is accessed for the first time.  After the copying, the access controller 300 converts access to the special area of the ROM file 100 into access to the buffer 200.   When the use of the ROM file device is finished, the data stored in the buffer 200 is returned to special area of the ROM file 100.

Title: True family telecommunication service
Inventor: WEBER ROY PHILIP
IPC: H04M15/00
Filed: 1996-05-22
Granted: 1999-07-20
Abstract: Entities who normally are financially responsible for calls made by them have their calls paid for by a sponsor when they are selected by the sponsor to be included in a "family ring" and they make calls to other entities that are included by the sponsor in the family ring. This capability is achieved with the aid of a database node which maintains information about the identity of members in the family ring. Operationally, in accordance with one embodiment, any member of the family ring who wishes to callanother member of the family ring calls a pre-designated number that connects the calling party to a database node. The database node interacts with the calling party by first determining whether the calling party is a member of the family ring, and when the calling party is authenticated, the database node responds to information that identifies a selected called party who is also a member of the family ring. The database nodeperforms a translation, as necessary, and informs the telecommunication network of the destination desired by the calling party. In response, the telecommunication network connects the calling party to the called party.
