Title: Regulation system for combustion gas mixing for boiler and heating systems - has gas and air supply valves mounted separately with air valve electrically controlled by gas valve
IPC: F23N1/10
Filed: 1990-11-22
Abstract: A combustion gas mixing chamber (1) is supplied with component gasses through feed lines (2,3) e.g. natural gas and air. Mixed gas is supplied from the mixing chamber to the burners (4). Gas supply is regulated by a conventional reversible servo motor operated ball valve (6,7).

Inventor: SMURKOSKI J A
IPC: D21F1/10
Filed: 1991-06-28
Abstract: A backside textured papermaking belt is disclosed which is comprised of a framework and a reinforcing structure. The framework has a first surface which defines the paper-contacting side of the belt, a second surface opposite the first surface, and conduits which extend between first and second surfaces of the belt. The first surface of the framework has a paper side network formed therein which defines the conduits. The second surface of the framework has a backside network with passageways that provide surface texture irregularities in the backside network. The papermaking belt is made by casting a photosensitive resinous material over and through the reinforcing structure while the reinforcing structure travels over a textured surface, and then exposing the photosensitive resinous material to light of an activating wavelength through a mask which has transparent and opaque regions. A process for making paper products is also disclosed which involves applying a fluid pressure differential from a vacuum source through the belt to a partially-formed embryonic web of papermaking fibers. The fibers in the embryonic web are deflected into the conduits of the papermaking belt by the vacuum pressure while the papermaking belt and the embryonic web travel over the vacuum source. Following the deflection, the paper web is impressed with the paper side network of the belt, and dried to form the final product.

Title: Method and device for dynamic regulation of the emitted power in the powerful amplitude modulated radio transmitters
Inventor: DONCHEV DONCHO P
IPC: H03C1/62
Filed: 1997-04-21
Abstract: The method and the device can be used in radio engineering. By them energy costs are reduced. By the method, depending on the level of the enveloping curve of the modulating low frequency signal,  the DC parameters  of the preliminary high frequency stages of the radio transmitter are changed. At low levels of the modulation signal, e.g. not exceeding 25% of its full swing, or when it is lacking (mode of silence) the amplitude of the carrier signal is reduced, thence - the swing of the excitation voltage of the final stage and the emitted and consumed energy. The device includes a detector (1) of the enveloping curve of the low frquency modulation signal and an actuation device (2) producing regulation voltages, respectively Uper+ to the screen grid and Uper- to the third grid of the preliminary high frequency amplifier.
