Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a boiler installation for the combustion of solid fuels, for example forest waste material in the form of e.g. bark and/or chips, peat pellets coal etc., which installation comprises a furnace located in connection to a heat medium portion and a grate means located in the furnace, which grate means feeds fuel from a fuel charge opening through the furnace while the fuel is being combusted, from which furnace the flue gases flow to the heat medium portion and continue to a chimney, and at least one intake for controlled supply of combustion air in the form of at least primary and secondary combustion air.  In order to improve the efficiency degree of such boiler installations and to render possible efficient and complete combustion of forest waste material and other biologic fuels J which may have a high moisture content, the rear portion of the grate means of the boiler installation, seen in the direction of movement, is located outside of the furnace space proper but connected thereto for forming a zone in connection to the charge opening for a certain drying of the fuel before it is fed into the furnace by the grate, and comprises transverse dogs running on a grate plane for advancing the fuel through the furnace, which grate plane is located above means for the supply of the primary combustion air from below to the fuel, and below the air intakes for the secondary combustion air.

Abstract: ABSTRACT           The present invention provides a completely self-contained intraoral larynx comprising a power source, tongue activated controls, power saving signal generation circuitry, acoustic and audio amplifiers, and an intra-oral speaker.          These components are contained within an otherwise conventional denture or dental prosthesis.  The device produces a high amplitude sound while minimizing current drain from the power source.  Laryngectomized patients require only short term training by a speech pathologist to use this device.  Intel-ligible speech is usual within an hour of such training, and facility rapidly improves.  The psychological barriers, post-operative physical limitations, aesthetic concerns and limited gestural communication traditionally associated with the use of extra-oral larynges is eliminated by the present invention.

Abstract: Abstract A heat exchanger is assembled from a plurality of tube-pieces, which are made of a thermoplastic material, and are arranged parallel to each other, and spaced apart, one from another, with tubular end-pieces connecting these tube-pieces.     In this design, the tube-pieces are com-bined to form groups of four, and these groups are combin-ed, in their turn, to form tube-bundles.    The spacings between the tubes of a tube-bundle are guaranteed by means of retaining plates, which are loosely pushed on, in a manner permitting shifting.     A plurality of these tube-bundles can be superimposed to form a high-capacity heat exchanger, and these tube-bundles can be securely con-nected to each other by means of the retaining plates. The process for manufacturing a heat exchanger of this type can take place in three steps:    1)  Combination of four tube-pieces to form a tube-group. 2)  Combination of a plurality of tube-groups, placed side-by-side, to form a tube-bundle. 3)  Combination of a plurality of superimposed tube-bundles, to form a large heat exchanger.

In the preferred embodiment, the reservoir is formed between the inner production tubing and the outer casing tubing, and conduits are connected to direct the natural gas from the production tubing into the reservoir.          Liquid/gas separators and dehydrator units are employed on wells as necessary, so that the natural gas stored in the reservoir is ready for transport.
