Title: Fully distributed message storage facilities in a distributed switching system
Inventor: BALES BRUCE MERRILL
IPC: H04M3/533
Filed: 1996-07-25
Abstract: Storing messages intended for a communication terminal in a service circuit associated with the local network of a switch node serving the communication terminal. A switch node may have one or more local networks and can use a service circuit of these networks to store the message. If the switch node does not havecapacity to store the message, the switch node will request that another switch node store the message. When it is necessary to process and store a message for a communication terminal connected to a local network, the service circuit associated with the local network may be busy and unable to process the call or the servicecircuit may not have sufficient memory to store a message. In which case, the switch node will attempt to find a service circuit with the ability to process the message and store the message on another local network controlled by the switch node. If theswitch node cannot find a single service circuit that has both processing capability and storage capability, the switch node will attempt to find a service circuit on one local network that has processing ability and a service circuit on another localnetwork that has storage capacity. The message is then stored on a local switching network of the other switch node. If the switch node request another switch nodestore the message, the other switch node uses the same procedures described above for identifying a service circuit and storage capability.

Title: Methods and apparatus for operating a discharge lamp
Inventor: MOSKOWITZ WARREN P
IPC: H05B41/392
Filed: 1997-01-14
Abstract: Methods of operating a discharge lamp by amplitude-modulating and pulsing the lamp input power waveform. The techniques control both the arc stabilization and color characteristics of the lamp, respectively. The alternating current (AC) input waveform is amplitude-modulated to stabilize the arc with a swept AC periodic wave (such as a sine wave, sawtooth wave, square wave, etc., or a combination thereof). The swept wave can be generally swept from about 20 kHz to 60 kHz, with a preferable band sweep of from approximately 40 kHz to 50 kHz. The sweep can also be patterned (such as allowing the sweep to have stepped rises and falls within the sweep cycle). The sweep may also contain multiple-frequency sweeps that are bundled together to modulate the carrier wave. These modulation forms are used to center, constrict and stabilize the arc. In addition to this stabilization, the lamp input waveform is pulsed to control and regulate the color characteristics of the lamp.

Title: Method for producing catalyst-grade alumina from aluminum sulphate
Inventor: RENDALL JOHN S
IPC: B01J21/04
Filed: 1997-03-18
Abstract: A method of making activated alumina includes beginning with a leach liquor of potassium and aluminum sulphates that is subjected to a surface-cooled crystallizer with a heat-exchanger input temperature of 160°F and a surface-chilled temperature of 60°F to 80°F.  Crystals of aluminum sulphate are precipitated and recrystalized by evaporation in a vacuum and at an elevated temperature.  Purified crystals of aluminum sulphate are then dried at 50°-60°C.  The dried aluminum sulphate crystals are then dehydrated at 400°-450°C after a rise rate of 10°-20°C per minute to drive off most of the water. A roasting and recalcination step at 900°C-950°C after a rise rate of 10°-20°C per minute is used drive off the sulphate.  The remaining alumina is useful as a high-grade catalyst.

Title: Method of varying amounts of heparin coated on a medical device to control treatment thereon
Inventor: LUNN ANTHONY C
IPC: A61F2/82
Filed: 1997-05-27
Abstract: The  present  invention  addresses  two  previously unresolved problems simultaneously.   First,  the question concerning the amount of heparin applied to a stent  is resolved.   That is,  the invention set forth herein will demonstrate that by varying the amount of heparin,  the practitioner  can  actually  more  adequately  determine whether  in  fact  the  patient  will  receive the  correct dosage to address the problem,  and at the right time in which to address  the problem.   Second,  the problem of applying the heparin  coating  to  a  stent  is  addressed. There, specifically, the invention turns to the fashion in which to apply multiple layers of heparin coating to the stent, and to thereby variably adjust the dosage applied to the patient at the lesion site.  The present invention does so by providing a method and device for coating a stent with multiple  layers of heparin coating.   By so doing,  the heparin coating is absorbed by the body in a degree which varies with the amount of heparin applied. Thus,  contrary to  formerly popular belief,  the present method allows for the significant adjustment of heparin therapy.  And, the stent so coated allows for the variable application of such heparin therapy at the lesion site.

Inventor: CHEUNG NELSON
IPC: B65B13/18
Filed: 1997-09-30
Abstract: In a pneumatically operable strapping tool, a tension lever is provided for controlling an internal pneumatic or air control valve which, in turn, controls an air motor drive operatively connected to a feedwheel which tensions the strapping material, disposed about an article or package to be strapped, to a predetermined tension level. A seal lever is provided in conjunction with the tension lever such that upon completion of the tensioning phase of the strapping operation, the seal lever may be actuated so as to initiate the sealing phase of the strapping operation. In order to prevent a partial loss or a reduction of the tension level within the strapping which normally occurs during the transition between the tensioning and sealing phases of the strapping operation, the seal lever is provided with a tang, tab, or ear member which physically encounters or engages the tension lever so as to maintain the tension lever at its operative or active position during the sealing phase of the strapping operation. In this manner, the tensioning phase of the strapping operation is not prematurely terminated and termination of the tensioning phase of the strapping operation is effectively delayed until the sealing phase of the strapping operation has been completed. Therefore, a proper tension level within the sealed strapping is achieved.
