Abstract: This invention relates to a bow sight and more particularly, but not exclusively, to an automatic bow sight which is releasably securable to a bow. The bow finder includes a range finder, a range finder aiming mechanism for use in assisting to aim the range finder at a target, a display arrangement including a plurality of fight sources that can be switched on independently and/or in combination, and a processor configured to receive information from the range finder, and to send an actuation signal to the display arrangement in order for at least some of the light sources to be selectively switched on.

Abstract: The invention provides a geyser (210) for heating water in domestic or industrial applications. The geyser (210) includes a first end section (212), a second end section (214), and a central section (216) between the first and second end sections. The central section (216) includes a plurality of modular components (218 and 220) defining an inner wall (316) which together with the first and second end sections (212 and 214) forms a primary, sealed chamber (C) for containing fluid within the geyser (210), in use, and an outer wall (318), spaced from the inner wall (316), which together with the inner wall (316) and the first and second end sections (212 and 214) forms a secondary, safety chamber (D) for containing fluid expelled from the primary chamber (C) upon failure of the geyser (210). An outlet (331) is provided on the geyser (210) for allowing fluid to discharge from the secondary, safety chamber (D), typically via a vent pipe, to a desired location.

Abstract: A silencer (10) includes a polymeric casing (12) spaced from at least one inlet pipe and at least one outlet pipe by polymeric spacers (52). The polymeric spacers are made from a different material to that of the polymeric casing. The polymeric spacers are heat-resistant and have a higher melting point than the polymeric casing. The polymeric spacers are made of a softer material than the polymeric casing, and the polymeric spacers are capable of being deformed to accommodate irregularities in the shape of the inlet and outlet pipes.
