Abstract: A solid state microwave generator is utilized as an excitation source for material/plasma processes. The invention provides very close precise control of the solid state device's power levels to control the ultimate power output and frequency which contol is not readily possible with vacuum tube devices. Utilizing the concepts of the invention the total power generated by the system may be easily varied and, further, the power may be easily monitored and used to control other device parameters such as frequency and the like. Because of the degree of control possible within the overall processs system of the invention any measurable physical property of the process such as temperature, power, color (e.g., optical pyrometer), or the like that can be monitored and converted to a control signal can be utililzed by the present system to carefully control the overall process conditions. These control features are lacking in currently available vacuum tube microwave devices. It is also probable that the overall cost of the solid state based microwave power generators systems will be far less than that of comparable tube type microwave generators.

Abstract: An air-starved, batch burn, modular, municipal waste incinerator is designed to oxidize unsorted loads of heterogeneous materials in quantities ranging from 5 to 500 tons per 12 to 15 hours. The system is designed such that through air mixing, air turbulence, and temperature control, it is possible to burn this material with a highly favorable stack emission product, without the need for bag houses, dry scrubbing, or other elaborate down stream air processing equipment. The incinerator includes a primary combustion chamber (12) connected to a secondary combustion unit (14) by a gas transfer tube (16,50). Solid material in the primary (12) is oxidized - or gasified - without live flame. Flammable gas is vented into the secondary (14) for ignition. Combustion gases from the primary chamber are completely burned in the secondary combustion unit (14) as the gases pass upwardly through an air mixing ring (66) and tangentially disposed re-ignition burners (70). The tangential orientation of the re-ignition burners (70) creates a vortex through which the combustion gases travel before exiting from the stack.

Abstract: The present invention relates to a process and to a machine for collecting dust and cleaning the interior of vehicles, in particular of the type intended for public transportation. The process consists in introducing inside the vehicle (4) a primary flow of low-pressure air (7) with a high flow-rate, which generates a conveyance current, channelled along a closed path which includes the interior of the vehicle (4), from at least one inlet opening (5) to at least one outlet opening (6). At least one secondary flow of air (9) at a higher pressure and with a lower flow-rate with respect to the primary flow is simultaneously fed into the interior of the vehicle (4). The secondary flow is orientated along at least one direction which intersects the primary flow and affects the floor (4a) of the vehicle so as to generate a turbulent motion which removes dust and objects, which are thus subjected to the conveyance action performed by the primary flow. The air which flows out of the outlet opening (6) is subjected to filtration (17,18) and is introduced again into the vehicle through the inlet opening (5).

Abstract: A method for image reversal, beginning with a negative photoresist material that is patterned by electromagnetic radiation at wavelengths of the order of λ = 250 nm. A negative resist material, Shipley SNR 248, is modified by addition of an amine-containing base compound such as 1,2,4-triazole to form a photoresist-base ("PB") mixture. A film containing the PB mixture is baked (optional), exposed to narrow band light at λ = 248 nm, using a photomask for the desired pattern, so that insufficient acid remains in the exposed portion of the film to promote cross linking. The base in the exposed portion of the film is removed by low temperature post-exposure bake so that no further cross linking occurs. The film is then uniformly exposed with a dose sufficient to cross link the previously-unexposed portion of the film, and the film is baked again at a low temperature. The film is then developed, producing a positive image of the original pattern.

Abstract: A digital signal encoding apparatus includes a circuit (10) in which an allowable noise level is set for each of plural frequency bands of an input digital signal on the basis of the energy from one band to another, and a quantization circuit (24) in which components of the signal in each of the frequency bands are quantized with a number of bits corresponding to the level of the difference between the energy of each frequency band and the allowable noise level. In the allowable noise level setting circuit (10), the allowable noise level of a particular frequency band is set on the basis of the energy of that particular frequency band and that of another frequency band, and a non-linear relationship is provided between the energy and the allowable noise level to enable data compression which is more intensive and more agreeable to the ear. Also, even if the input digital signal is preemphasized (20), the allowable noise level setting is made on the basis of a signal corrected (22) for preemphasis, so that quantization may be performed in a manner free from the effects of preemphasis.

Abstract: Hardware complexity of transmitting and receiving equipment in a CDMA (Code Division Multiple Access) cellular radio transmission system is reduced by the use of frequency modulation (FM) techniques to achieve spectral spreading in combination with signal modulation. 
     The spectral spreading technique of a CDMA cellular radio telephone communications system is generalized by extending the range of values allotted to the spreading waveform code signal to include complex numbers of unity magnitude. This permits the addition (in 307) of a baseband version (at 301) of the information signal and spreading waveforms (from 303,305) instead of the conventional multiplication of the two signals in existing DSSS (Direct Sequence Spread Spectrum) communications systems. The resultant summed signal is used to control a Voltage Controlled Oscillator (309) to produce (at 312) a frequency modulated spread spectrum signal to be transmitted. This arrangement permits improved and more efficient implementations of the transmitting and receiving equipment.

Abstract: A remote telecommunication terminal providing telecommunication functions identical to those functions provided by local telecommunication terminal directly connected to a telecommunications system via a direct standard link using a standard protocol. The remote telecommunication terminal is interconnected to the telecommunication system through an intervening switching system such as the public telephone network. One such remote telecommunication terminal is a remote telemarketing terminal. A remote telemarketing terminal cooperates with the telemarketing system to establish a virtual interface on the telemarketing system. The telemarketing system views this virtual interface as being identical to a physical interface such as one connected to a local telemarketing terminal via a standard link. The remote telemarketing terminal then establishes a virtual link between itself and the virtual interface on the telemarketing system. The virtual link is established on transport channels of standard links that interconnect the remote telemarketing terminal to the switching system and from the switching system to the telemarketing system. The switching system is unaware of the establishment of a virtual link on these transport channels and does not respond to signaling information on a virtual signaling channel of the virtual link. The telemarketing system controls the telemarketing functions of the remote marketing terminal by transmitting signaling information via the virtual interface and the virtual signaling channel to the remote telemarketing terminal in the same manner as the telemarketing system controls a local telemarketing terminal via the signaling channel of the standard links connected to the local telemarketing terminals. The standard links may be either ISDN PRI links or BRI links and the standard protocol may be the ISDN protocol.
