Abstract: A method and apparatus for delivering coded information using mobile phones with a display. The method is characterized in that the coded information includes element codes, the elements of which are selected from character sets supported by short text messaging systems and disseminated by, but not limited to standard SMS distributed via SMCS. The element codes do not require EMS, MMS or other more complicated communication elements and can therefore be simply and efficiently delivered to practically every mobile phone and be used for ticketing, couponing and access control purposes. Apparatus is provided for performing the method.

Abstract: A digital camera is equipped with means for recognising if the information in an image is text- or image-based, or can also be used for conventional digital photographing. It is also equipped with optical character reading-means (OCR). Several methods of using such a camera are described, e.g. ordering articles and services from advertisements or catalogues; creating case records for medical care; transmitting hand-written letters and messages by mobile phone; registering and manipulating documentation from appointments and conferences; and controlling flows of packets, goods or products.

Abstract: A method is provided to control an energy recovery system to achieve an increase of the statistical average system recovery efficiency. The system includes at least one fluid accumulator tank (6, 20, 30) and at least one heat exchanger (10, 25) for waste process fluid or gas. According to the invention the flows through the primary or secondary side of the heat exchanger (10, 25) is at each time continuously controlled by a parameter being a function of both the actual temperature and the actual fluid volume in said accumulator tank (6, 20, 30).

Abstract: The gas flow is ionized by its being caused to pass an emission electrode means (2) so that ions are formed and the polluant particles are given an electric charge. The particles are deposited by electrostatic attraction onto a combined collector electrode/heat exchanger surface (6), there also being generated a new aerosol by the gas flow being cooled as it passes said collector/heat exchanger surface, pollutants in the gas phase condensing onto the ions and electrically charged particles serving as condensation cores simultaneously as heat is recovered from the gas flow. The apparatus includes a heat exchanger (1) of the tube type, having a plurality of emission electrode means (2, 3, 4) inserted between groups of heat exchanger pipes. The collector electrode/heat exchanger surfaces on the pipes can be cleaned by a cleaning means (5) during operation of the apparatus, and in some applications the emission electrode means can also be automatically cleaned.

Abstract: Heat recovery from corrosive gases such as sulphurous flue gases and/or flue gases containing organic acids, said corrosive gases being conducted through a primary side of heat exchanger means (I-II) provided in a gas duct (1).Said heat exchanger means are provided with means for repeatedly applying, during normal operation of said heat exchanger means, a protective controllable thin layer to the surfaces of said heat exchanger means, at least whenever the temperature of said corrosive gases exceeds the water dew point, in order to protect said surfaces from corrosion.

Abstract: A figure of effectiveness of a heat exchanger is maintained at a predetermined level, even when one of the input fluid flows varies in an incontrollable manner, without the need for flow meters to detect any flow variations. Temperature sensors are arranged in the respective input and output fluid lines to measure the temperature of the fluids at these points and differential circuits and a comparator form a temperature relation that is compared to a predetermined, desired temperature relation to drive a servo system to control a flow value in the inlet water line, which results in the desired figure of effectiveness for that heat exchanger without measuring the actual fluid flow.

Abstract: Contaminated air is treated to attain a predetermined temperature, purity and relative humidity using an apparatus which includes heat exchange elements and water spray nozzles. The heat exchange elements comprise tubes arranged to impart turbulence to the contaminated air flowing over the tubes. Water is sprayed into the air flow against the tubes and water droplets intimately mix with the air flow so that the contact surfaces of the tubes simultaneously perform three functions: purification of the air, humidification of the air to a relative humidity of about 100%, and bringing the air to a desired temperature. Purification occurs when the air-water droplets hit the outside contact surfaces of the tubes. Impurities contained in the air are deposited on the contact surfaces to be washed away by the water spray. Humidification occurs when the spray water on the contact surfaces is vaporized by the addition of heat from a heat transport fluid conducted through the tubes.

Abstract: An apparatus for the treatment of a gas, air in particular, having an elevated temperature and being contaminated by condensable pollutions, to purify the gas and recover heat. The apparatus aims at a high efficiency of heat recovery as well as purification of the gas while simultaneously avoiding environmental pollutants problems.According to the invention the method is characterized by transferring heat from the gas to a heat collecting fluid by means of a system of heat transferring surfaces, while applying to the gas a turbulent flow. By cooling the gas, the contaminations present therein are transferred into a solid or liquid state, the turbulence enhancing an aggregation of condensed contaminations and the deposition of the contaminations onto the heat transferring surfaces, said surfaces then being mechanically and/or chemically and/or thermically cleaned, as the case may be with the apparatus used for executing the method in operation.

Said method comprising the steps of collecting waste heat in emitted fluid or fluids at every waste heat source of group of mutually similar waste heat sources and assorting said waste heat with regard to temperatures and as required accumulate it at the highest temperature as possible. Collected heat is then fed back directly or indirectly via the accumulators to the heat requiring unit the temperature need of which is with as low value as possible below the temperature of the feed-back heat. Said apparatus is characterized in that said waste heat sources (M.sub.1 -M.sub.
