Title: Method of routing electronic messages
Inventor: ABALI BULENT
IPC: G06F15/173
Filed: 1993-06-30
Granted: 1997-02-25
Abstract: A method of  sending an electronic message from a source station  through  a  network  of  switches  and  links  to  a destination station. An electronic message is sequentially sent to each of a series of switches. Each switch reads a route  signal  in the message  and sends the message to  a switch or a station having an input port connected to an output  port  identified  by  the  route  signal.  The  route signals are generated by storing a weight for each switch link in the network.  Candidate paths  through the  switch network starting at the source station and ending at initial candidate   destinations   are   identified.   Each   initial candidate destination has an input port directly connected to an output port of a switch having an input port directly connected to the source station.  If one or more candidate destinations are the destination station,  a candidate path ending at the destination station is selected, and a series of route  signals corresponding to the  selected candidate path  is  generated.  If  no  candidate  destination  is  the destination station,  extended candidate paths are formed. Each extended candidate path has a path weight comprising the weights of switch links along the candidate path. If one or more extended candidate destinations are the destination station, a candidate path ending at the destination station and having a path weight better than or equal to the path weight  of  each  other  candidate  path  ending  at  the destination station is selected.  Otherwise,  the candidate paths are again extended.

Abstract: A microprocessor provides a pulse width modulated pulse train at a predetermined frequency to a tuned resonant circuit having a transducer element. The first pulse has a predetermined width. The pulse widths of successive pulses are decreased in a predetermined manner until the pulse width reaches a minimally desired width. The next generated pulse has the first predetermined width and each successive width is decreased in the same predetermined manner. This pattern is generated repeatedly. Each one of these generated patterns produces an audible waveform from the tuned resonant circuit which changes over time. If the pulse train frequency, the pulse width modulation, and the circuit's resonant frequency are chosen correctly, the audible waveform will have the same characteristics as the waveform produced by a specified bell which has been struck.

Title: Method of addressing a matrix-array type liquid crystal cell
Inventor: SURGUY PAUL
IPC: G09G3/36
Filed: 1992-08-07
Granted: 2002-11-26
Abstract: A method of addressing a matrix of ferroelectric liquid crystal cells involving the blanking of all lines of pixels within the display prior to addressing with information for display. The blanking pulse (16) has a lower amplitude (Vs/m) and a longer du-ration (mt) than the select pulse (12). By reducing the amplitude of the blanking pulse (16), it may be applied to a given line at or below eight lines before the necessary select pulse {12) is applied in order to display information. This has the effect of maximis-ing the display brightness and reducing flicker.

Title: Filtering device
Inventor: KUPKA MARTIN
IPC: B01D33/00
Filed: 1993-05-12
Granted: 1999-12-14
Abstract: Described is a filter apparatus equipped with tubular filter elements comprising perforated pipe sections with filter media attached to their outer faces. The flow of the liquid to be filtered is directed onto the filter bodies transversely of the pipe section axis. The filter bodies are preferably disposed in a circular array and interconnected to form a cage acting as a rotor revolving within a casing supplied with the liquid to be filtered.      A plurality of such cages may be concentrically nested within one another, with neighbouring cages revolving in opposite directions. This results in the creation of pulsing flow patterns in the liquid to be filtered, which act to prevent premature clogging of the filter media by sediments thereon.

Granted: 2005-04-12
Abstract: Sprayable fireproofing compositions for structural members such as steel columns are provided. The compositions comprise a cementitious binder such as Portland cement, and a hard aggregate containing water of hydration. Such hard aggregates contribute not only to the strength of the fireproofing composition, but also contribute thermally. The product is produced by dry blending a mixture of the cementitious binder and hard aggregate, as well as other optional additives. Upon the addition of water, sprayable slurries are formed which can be pumped to the point of application. An accelerator is added in close proximity to the point of injection. Other additives may also be included, such as starch, adhesives and cement strength enhancers. The slurries adhere to the structural member in the slurried state and after setting to provide excellent fire and heat protection.

Abstract: There is disclosed a method of charging fine-grained ore into a reactor pressure vessel through which process gas flows. The heated ore at first is introduced into a conveying pressure vessel, is pressurized within the same by compressed gas and subsequently is conveyed into the reactor pressure vessel through a conveying duct by aid of thecompressed gas. In order to ensure favorable utilization of the reactor pressure vessel under uniform stress and to safeguard troublefree progression of reduction while directly charging the ore, a portion of the ore is introduced into at least one further conveying pressure vessel and is pressurized within the same also by compressed gas. Charging of the ore into the reactor pressure vessel is effected continuously by alternately feeding once from the one conveying pressure vessel and subsequently from the other conveying pressure vessel. The compressed gas is taken from the process gas as a quantitative or as a component portion of the process gas and is fed back to the same along with the ore.
