Abstract: An apparatus for simulating a solid fuel fire comprises a sheet, preferably in the form of a holographic photopolymer film carrying a holographic image of a bed of fuel and flame effect means co-operating with the holographic sheet whereby the flame effect appears to emanate from the holographic image of the fuel bed, resulting in a very realistic effect and allowing the depth of the apparatus to be reduced.

Abstract: In a process for processing a hologram, a holographic image is formed in a photopolymer layer carried on a substrate. A colour tuning film is applied to the opposed photopolymer layer to form a laminate. The temperature of the laminate is raised and is subsequently cooled and is then exposed to a source of curing electromagnetic radiation.

Abstract: The present invention discloses a control for a gas fire, the control comprising a support member in which an elongate aperture (1) is formed, and a slide member (5), part (7) of which slide member (5) projects through and is manually movable along said elongate aperture (1). Said slide member (5) is connected via a linkage (9,35) to a gas burner control lever (11) whereby movement of said part (7) along said elongate aperture (1) causes said slide member (5) to move said gas burner control lever (11) between two end regions of available movement, to control a valve (13) and the feed therethrough of gas from a gas inlet (19) to at least one burner. One microswitch (23) is operable by the control lever (11) to activate an igniter (25) towards one end region of the available movement of the control lever, and another microswitch (31) is operable by the control lever (11) to activate and interrupter (17,29) which can close off the supply of gas.

Abstract: A simulated solid fuel effect gas fire comprising two elongate simulated solid fuel elements in the form of logs, with a partially aerated gas burner arranged in front of and below each log with respect to the front of the fire. Thus, in use, the flames from the burners engage a lower front portion of the logs, the flames then passing around the front of the logs. By this arrangement the lower front regions of the logs are heated to glow as radiants and the flames subsequently lick around the front of the logs as yellow flames, in accord with the visual effect of a real fire, complete combustion having been attained in the ambient atmosphere in front of the logs to thus form the yellow flames. By the provision of nodules by virtue of a bark pattern on the upper front portion of the logs, the flames heat the nodules to red heat and enhance both the radiant heat derived from the fire and the visual effect of the fire.

Abstract: The present invention relates to a method and apparatus for use in installing a gas fire in a fireplace. The apparatus comprises an adaptor member in the form of a planar plate from which a flue spigot projects upwardly, the flue spigot in use, being connected with a flue liner. The planar plate has a rearward end section which is interengageable with a rearward part of the fire whereby the planar plate can subsequently be pivoted to a position wherein a front section of the planar plate can be secured to the fire. Said rearward end section and said front section of the planar plate are thus secured to the fire, holding the planar adaptor member flat against the upper surface of the fire with the flue spigot aligned with a flue passage in the fire.

Abstract: The present specification relates to a ceramic plaque burner and to its method of construction. The plaque burner is formed as a generally planar plate with a number of parallel, narrow slit burner apertures extending therethrough. The present invention provides a ceramic plaque burner comprising a number of elongate ceramic members which are arranged parallel to each other with spacers located therebetween, a bezel engaging around the elongate ceramic members and said spacers to hold the assembly together. This construction is relatively simple and inexpensive to manufacture and avoids the problem of thermal stress cracking at the end regions of the burner slits.
