Title: Voice mail network gateway
Inventor: ANDERL EWALD CHRISTOPH
IPC: H04L12/54
Filed: 1994-10-24
Abstract: A voice mail network processes messages according to the media format desired by the recipient independent of the media format used by the sender. Forexample, a "gateway" to a voice mail network receives an e-mail message from an e-mail sender, and processes the e-mail message into a multi-media message format. The gateway of the voice mail network then checks a "user profile" associated with the recipient of the e-mail message. This profile stores user-specific information and includes the media preference of the user. The gateway retrieves the media preference for the recipient from the associated user profile and sends the multi-media message to the recipient in the preferred format. This allows a voice mail user to receive voice mail notification of any message transmitted to them regardless of the media used by the sender.
Patent CA-2134800-A1 (CA)
Title: Method and apparatus for the billing of value-added communication calls
Inventor: LEWIS C ALAN
IPC: H04M15/00
Filed: 1994-11-01
Abstract: ABSTRACT    A new method of charging enhanced service provider (ESP) fees on phone bills of telephone numbers originating seven digit 555 number calls within The Public Switched Telephone Network (PSTN).  The Local Exchange Carrier routes the call to the PSTN which translates a dialed 7-digit 555 number into a ten-digit phantom routing number and then passes the call to the carrier assigned the ten-digit routing plan.  Translation is performed as a look-up in a database, i.e., the Service Management System (SMS).  The SMS is used for 800-number translation and was not heretofore available to ESPs. This novel use of PSTN facilities enables the system to provide caller dialed number and billing information on a real-time basis (during call processing).  It signals the billing and caller dialed number information in the voice channel (In-Band) during setup of calls to connecting carriers.  The ESPs receive the circuit "off-hook" signal (seizure), and two fields of Multi-Frequency Tones, then process the information to collect and validate billing information needed to deny the call or to accept it.  If the ESP accepts the call, the caller dialed information is processed to bill or credit the subscriber for the service the caller selected.  Using a phantom routing number bridging circuit between the Local Exchange Carriers and the toll carriers in a manner similar to 800 call processing allows the billing information to remain intact through-out the call hand-off from the carriers to the ESP.

Title: Gate controlled lateral bipolar junction transistor and method of fabrication thereof
Inventor: MALHI DULJIT S
IPC: H01L29/73
Filed: 1994-11-16
Abstract: A gate controlled lateral bipolar junction transistor (GCLBJT) device for an integrated circuit and a method of fabrication thereof are provided.  The GCLBJT resembles a merged field effect transistor and lateral bipolar transistor, i.e. a lateral bipolar transistor having base, emitter and collector terminals and a fourth terminal for controlling a gate electrode overlying an active base region.  The device is operable as an electronically configurable lateral transistor.  Advantageously a heavily doped buried layer provides a base electrode having a base contact which surrounds and encloses the collector.  The surface region between emitter and collector is characterized by lightly doped regions adjacent and contiguous with the heavily doped emitter and collector, which effectively reduce the base width of the bipolar transistor and improve operation for analog applications. threshold adjust implant in the surface of the base region under the gate electrode allows for control of threshold voltage of the surface MOS channel.  Performance parameters of the bipolar transistor may be adjusted via a signal to the fourth i.e., gate, terminal, to control inversion under the gate, thereby controlling the path of carriers between the emitter and collector.  Transistor performance characteristics such as common-emitter current gain, unity-gain frequency, and the low frequency noise properties are all variable quantities which can be specified electronically, i.e. they are programmable by a signal applied to the gate.  Concurrent use of field effect and bipolar injection phenomenon within the same device yield the salient device characteristics.  Applications include mixer and modulation circuits.

Inventor: MIZUKI TATSURO
IPC: B60R21/16
Filed: 1995-02-03
Abstract: A high-strength ultra-fine fiber construction including a high-strength multi-filament yarn including ultra-fine filaments of a fineness of a single filament less than 0.8 denier, a tenacity of 6.5 g/d or more, and the elongation at break of the multi-filament yarn being 15% or more.  In order to obtain such a fiber construction, islands-in-sea-type or divisional type conjugate spinning is initially carried out to obtain conjugate multi-filament yarns, which is subjected to weaving to produce a fabric, and a island component removing or dividing treatment is finally done in order to obtain the high-strength ultra-fine fiber in the fiber structure.     Ultra-fine fibers of the desired strength together with a particular range of a cover factor provides all the advantages of the ultra-fine fibers.  A reduced air permeability, when it is necessary, can be easily obtained.  Namely, a desired mechanical property as well as a desired softness are both obtained, while the number of naps and filament breakages are reduced.  An air bag as the fiber construction can attain any desired properties such as high mechanical strength, a large degree of softness, a neatness when folded, and a low air permeability.     Furthermore, a method is also disclosed, for producing the fiber construction, which allows melt spinning as well as weaving to be executed while preventing any occurrence of operational difficulties, such as naps and filament breaks.

Title: Procedure for reconditioning standardized bung-type drums that are of plastic
Inventor: SCHUETZ UDO
IPC: B65D8/00
Filed: 1995-09-19
Abstract: Reconditioning standardized bung-type drums that are of plastic, that are manufactured in one piece by blow moulding or which consist of a blow-moulded body with an injection moulded head that is welded on, for renewed use as bung-type drums or use as wide-neck drums, when the reconditioned bung and wide-neck drums are of an identical nominal volume and an identical height and diameter according to DIN standards is carried out by first effecting mechanical separation of the head transversely to the longitudinal axis of the body.  In the case of bung-type drums with a head that is welded on, the separating cut is made beneath the welded seam.  There follows preparation of the annular cut edge of the body to produce a smooth weld surface and cleaning of the drum body.  The cut edge of the drum body is then calibrated followed by welding on of a head that incorporates a filler and removal bung and a ventilation and air-removal bung on the calibrated cut edge of the body to produce bung-type drums, smoothing of the welded seam, and an integrity check of the bung-type drum.  There is then welding on a neck ring having a rim that extends radially outwards at the lower edge, the diameter of which is smaller than the diameter of the drum body, on the calibrated cut edge of the drum body to produce wide neck-drums.  The welded seam between the drum body and the neck ring is smoothed and an integrity check made of the body and attachment of a wide-neck drum cover or a bung-type cover with a cover flange on the lower edge of the cover, on which the body neck ring is welded, with a clamping ring. The reconditioned bung-type and wide-neck drums are of an identical nominal volume and are of identical height and diameter according to DIN standards.

Title: Power process utilizing humidified combusted air to gas turbine
Inventor: FAN ZHEN
IPC: F02C7/08
Filed: 1995-12-14
Abstract: A process for producing mechanical power utilizing compressed humidified hot air and a fuel, which are mixed together and combusted and the resulting hot combustion gas is expanded through a gas turbine.  The air is initially compressed and intercooled against a water stream, and then further compressed and passed directly to a heat recovery unit where it is humidified using the water from the compressed air intercooling step.  The compressed humidified air is further heated and combined with a fuel in a combustor, and the resulting hot combustion gas is expanded through a gas turbine to produce mechanical power needed for driving the air compression.          The hot turbine  exhaust gas  is  cooled against the  compressed humidified air stream  and against the  water  stream,  and  then discharged to the atmosphere.  By eliminating a usual separate air aftercooling and  saturator  unit  upstream of  the  air  combined humidifying and heating step, process thermal efficiency for the present process is increased and equipment cost reduced.
