Abstract: ABSTRACT OF THE DISCLOSURE         A gas burner assembly for a fireplace is shown.          The assembly is operative to produce a flickering yellow flame pattern which closely resembles to that produced by a natural wood log fire, yet there is virtually no formation of carbon monoxide gas. The assembly generally comprises four artificial logs arranged in a predetermined spaced relationship to a gas burner. The gas burner consists of an opened top rectangular casing filled with non-combus-tible particles or a honeycomb gas distribution tile made of refractory material. The gas pipe is located adjacent to the bottom of the casing and having a plurality of openings facing downwards. The artificial log comprises a flexible metal tube wrapped with a ceramic fibre blanket which is impregnated with a colloidal compound and thermally cured.          The surface of the log is textured and painted to simulate the appearance of a natural wood log.

Abstract: Arc-over in the cathode ray tube (21) of a digital television receiver produces a large current pulse which, when it discharges via the chassis ground, disrupts the reference ground potentials of other circuitry coupled to the chassis ground. The affected circuitry includes digital data storage elements which may experience random state changes caused by the fluctuating ground potential. The CRT arc-over condition is detected by circuitry (460-466) which applies a pulse to the reset terminal of a microprocessor (440), causing it to restore the potentially corrupted data in the data storage elements using preset data stored in a less volatile programmable read only memory (452).

Abstract: @ The present invention pertains, in a particularly preferred embodiment, to an apertured, macroscopically expanded, resilient three-dimensional polymeric web which is believed to have particular utility as a breatheable barrier for a disposable bandage such as a diaper. The web preferably comprises a deeply drawn three-dimensional structure containing a multiplicity of debossments of macroscopic (i.e., visibly perceivable by the normal human eye at a perpendicular distance of about one foot) cross-section, each of said debossments originating as an aperture in a first surface of the web and having a continuously interconnected side wall extending in the direction of a second, remotely located parallel surface of the web. The side wall of each debossment terminates to form an end wall in the second surface of the web. The end wall includes a multiplicity of apertures, each of said apertures being sized and shaped to independently support an aqueous fluid meniscus. The smaller apertures in each end wall are so spaced relative to all adjacent apertures in the end wall that the aqueous fluid menisci supported in the apertures do not contact one another or the side wall. In a disposable absorbent bandage context, the second surface of the web containing the end walls with small apertures therein is placed in contact with the absorbent core portion of the bandage and the surface of the web in which the debossments originate is oriented so as to contact the wearer's outer garments in use.

Abstract: A sealing ring (2) for a bushing of a pipe or fitting (especially consisting of plastic) contains a central sealing lip (10) and two additional lips (12, 14), arranged symmetrically with respect to a plane (4) of symmetry. Such a sealing ring is normally inserted into the bead of the bushing after production of the pipe or fitting and there is a risk that the sealing ring may fall out before production of the connection between the tip end which is to be inserted and the bushing or the pipe. The invention is based on the object of, on the one hand, arranging the sealing ring reliably in the bead and, on the other hand, producing an insertion resistance which is as small as possible. It is proposed that the additional lips (12, 14) be designed as strip-off lips having a larger internal diameter than the central sealing lip (10) and that in each case the base (20) of the intermediate spaces (16, 18) present between the said lips be arranged at a distance (24) from the outer surface (22) of the sealing ring (2), which distance (24) is essentially of equal size to the height (26) of the central sealing lip (10), likewise related to the base (20). <IMAGE>

Abstract: An improved semi-submersible unit for use in offshore operations which has a significantly reduced susceptability to heave motions in wave periods which are most likely to be encountered during practical operation conditions. The unit consists of a lower hull or hulls supporting vertical buoyant caisson which also support an upper deck or platform which supports and is supported by a centrally disposed, large diameter buoyant caission which contributes a significant portion of the total water plane area of the vessel when it is submerged to its operational draft. The vessel may be configured for offshore drilling operations, diving support, and various other offshore support functions. When configured for the offshore drilling operation, the central column serves as buoyant chamber and as a primary storage chamber for tubular products which are associated with the drilling function. This clears the deck of the vessel for other operations and introduces a less hazardous method for handling tubulars than in previous designs. The central caisson has an interior annulus which is open both to the drill floor and the sea through which operations may be carried out. The improved semi-submersible vessel exhibits significantly less heave in operational wave conditions than existing semi-submersibles or similar water plane area and displacement.
