Abstract: ABSTRACT         A multi-zone boiler designed to be fired alternatively with solid and liquid fuel.  The boiler comprises a hopper (3) for the solid fuel and a burner (9) for the liquid fuel.  The hopper communicates with a combustion chamber (10) which, in turn, communicates with flue gas ducts (11, 12, 18A, 18B) made as heat-exchangers and leading to a flue (15).  The boiler has two said flue gas ducts or two groups of said flue gas ducts, and means (16, 16A, 16B) whereby one or other of the flue gas ducts or one or other of the groups thereof may be dis-connected either fully or partly to a selected degree from the path of flow of the flue gases, depending on the choice of fuel and/or the consumption of energy for space heating and/or water heating.

Abstract: ABSTRACT A casting form for use in casting concrete building walls is dis-closed which features a first substantially flat section in which the bulk of the wall is formed and a second tapered section which forms an integral footer/foundation.  The extent of the flat portion and the angle and depth of the tapered portion are variable in response to the building engineering requirements, including the load capability of the soil at a predetermined building site.  When these have been determined, the casting form is adjusted to provide a unitary wall and footer of predetermined dimensions suitable for a specific building.  In this way, casting of concrete to form either footer or wall at the building site can be eliminated.

Abstract: STABILIZATION OF CARRAGEENAN-CONTAINING TOOTHPASTE            ABSTRACT OF THE DISCLOSURE:         A method for stabilizing a cosmetic composition containing carrageenan, specifically, a toothpaste, wherein microwave radiation, preferably in the 0.8 to 3 gigahertz frequency range, is directed onto the toothpaste so as to raise its temperature to at least the gel-sol transition temperature of the carrageenan, after which the toothpaste is quiescently cooled to room temperature.  The use of microwave radiation facilitates an even heating of the toothpaste, so that temperature sensitive components thereof are not adversely affected, and promotes excellent control of temperature regulation.  Heating of the dentifrice, with improved thickening and stabilization thereof, is obtainable by passing it through a conduit while directing microwave radiation onto it and then filling it into suitable dispensing containers, or by filling the dentifrice into such containers and then subjecting them to microwave radiation.

Abstract: . 31076 ABSTRACT OF DISCLOSURE           A process is described for making sterically stabilised non-aqueous dispersions of composite polymer microparticles, in which (1) monomers including at least one crosslinking monomer are polymerised in an aqueous medium at a temperature at least 10° higher than the glass transition temperature of the polymer to be formed, in the presence of a block or graft copolymer stabilising agent, under conditions such that there is at no time present a separate monomer phase, (2) further monomers, not including any crosslinking monomer, are polymerised in the dis-persion thus obtained, the presence of a separate monomer phase again being avoided, and (3) the microparticles are transferred from the resulting dispersion into a non-aqueous medium which is a solvent for the non-crosslinked-polymer generated in (2). The microparticles are of value for incorporation into coating comp-ositions the main film-forming constituent of which is compatible with the non-crosslinked component of the particles.

The video signal corresponding to a picture having received such a code thus incorporates black or white signals located at the start and finish of a scanning line.  The decoder comprises a circuit for detecting, in the video signal which it receives, the presence of white and black signals located at the start and finish of the line and for recognising, on the basis of the thus detected signals, the presence of said code and for transmitting a control order.

Abstract: Abstract of the Disclosure An apparatus for continuously casting strip material is disclosed comprising a tundish having an internal cavity for receiving and holding molten metal and an orifice passage defined between two spaced lips in the tundish through which the molten metal is delivered from the cavity to a casting surface located within about 0.120 inch of the orifice passage and movable past the orifice passage at a speed of from 200 to 10,000 linear surface feet per minute.  In the present invention at least one aperture is provided through the tundish to a portion of the internal cavity of the tundish and a removable plug is disposed in the aperture.  The aperture must be large enough to divert molten metal in the internal cavity therethrough, and thereby reduce the metallostatic head pressure at the orifice passage below that pressure necessary to cast strip material.  A method of substantially instantaneously stopping a casting operation is disclosed comprising the step of selectively removing a plug from an appropriately sized aperture in communication with a tundish cavity.

Abstract: "BIMETALLIC WELL SCREEN FOR USE IN INJECTION WELLS AND METHOD OF MAKING SAME"                                 ABSTRACT           Mounting arrangement for a bimetallic pipe base well screen which must operate at elevated temperatures utilizes a weld for joining one end of a cylindrical screen member to the outer surface of an internal pipe member which has perforations along a portion of its length underly-ing the well screen.  The opposite end of the screen member, which has a greater temperature coefficient of expansion than the pipe base, has an in-ternal boss or ring portion which, at room temperature, has a smaller inner diameter than the outer diameter of the pipe base.  The ring portion is heated and shrunk-fit onto the pipe base to a degree that at operational temperatures it will either expand slightly out of contact with the pipe base, or at least become substantially unstressed, thus preventing damage to the screen member while also blocking out the entry of particles.

Abstract: IN THE ABSTRACT OF THE DISCLOSURE The described method and apparatus are relative to the indirect measurement of thermal energy delivered to numerous heating elements, part of one or several zones, for instance all the radiators in an apartment or all the radiant panels of single family quarters. The apparatus consists of a temperature sensor which outputs an electric signal depending upon the temperature of the carrying fluid in which it is immersed and corrected as a function of the type of heating unit used (radiators, fan-coils, radiant panels, convectors, etc.) since each system has a different thermal emission for an equal temperature of the fluid, an electronic circuit for processing the signal, valving devices for interception of the heat carrying fluid, and a counter device sensitive to the processed temperature signal, which device is sensitive to the added energy supplied, in a given time period to the various controlled rooms, each room having attributed to it its own thermal capacity by means of a programmable scaling circuit, when the interception valving devices for the heat carrying fluid let this fluid through.
