A counter flow indirect evaporative heat exchanger (10) having vertically stacked alternate counter flow wet (14) and dry (12) passages where the wet passages are wetted during operation of the heat exchanger by wetting means (50, 52, 53, 54, 70, 72, 74, 76) travelling vertically of the stack. Elongately wetting of a small plurality of the total number of passages (14, 12) of the heat exchanger (10) occurs at a time during vertical travel of the wetting means.

This invention is a pivot assembly 10 that connects mirror head 11 and a mirror mounting bracket 12 of a rear vision mirror that comprises a spigot 17, a plate 14 with an aperture 26 that is journalled to the spigot 17. A detent is located between the plate 14 and the spigot 17 which holds these components together to in turn hold the mirror head 11 in at least one required position with respect to the mirror mounting bracket 12. The detent changes from a locked position where the plate 14 is held with respect to the spigot 17 to a disengaged position when the plate 14 is rotated with respect to the spigot 17. A spring 40 acts against the detent to hold it in its locked position. The spring 40 yields to allow the detent to move to its disengaged position as the plate 14 is rotated with respect to the spigot 17. An attachment mechanism is provided both on the spigot 17 and the plate 14 that allows the spigot 17 to be secured to either one of the mirror head 11 or mirror mounting bracket 12. The plate 14 also has an attachment mechanism which allows it to be secured to the remaining component so that the mirror head 11 can be rotated with respect to the mounting bracket. The invention provides a pivot assembly 10 which is modular in nature and enables standardization of a pivot between various mirror head 11 and mirror mounting bracket 12 designs.

A method of controlling the operation of an evaporative air cooler where the pads (2) of the cooler are intermittently wetted with an amount of water (14) in excess of the capacity of the pads (2) to absorb and retain during each wetting operation of the pad. The airflow (20) through the pads during intermittent wetting being limited to a velocity so as to not entrain water in the airflow during the wetting operation and the velocity of the airflow through the pads is increased after each intermittent wetting so as to raise the level of cooling output (22) of the cooler between each intermittent wetting operation.

This invention relates to a mirror head (10) for an external vehicle mirror that comprises a load carrying structure (11) that is located within the mirror head, a connector (16) on the load carrying structure (11) that connects the mirror head (10) with respect to the vehicle, a shell (12, 13, 14) forming the external surface of the mirror head (10) within which at least a portion of the load carrying structure (11) locates, said connector (16) being positioned to enable connection with respect to the vehicle, and foam within the internal cavity of the shell (12, 13, 14), that acts to bond the load carrying structure (11) with respect to the shell components (12, 13, 14). This assembly provides a lighter mirror head (10) by comparison to conventional construction techniques while at the same time remaining rigid. It provides a means whereby loads can be transferred to the foam which are in turn transferred to the external shell components (12, 13, 14) of the mirror head (10).

A vehicle external mirror assembly (10) comprises three main parts: a vehicle-to-mirror assembly attachment bracket (15), a mirror housing (20) and a mirror (41). Housing (20) comprises a thin molded external plastic shell (50) and a foam core (21), the foam anchoring and supporting the shell. A load diffuser (45) may be positioned within foam (21) to reduce the maximum tensile and compressive stresses within the foam (21). Attachment bracket (15) is of a similar construction with a thin shell (15) internal foam (18) and load diffuser (16).
摘要:
The present invention is a mould and a method of moulding a plastic component using the mould that enable the manufacturer of a moulded component (45) which has an external covering. The method of moulding comprises either locating a pre-formed component (41) into a first part of the mould or vacuum forming a thin film (40) into a mould cavity. A first mould part (15) has a mould cavity into which the pre-formed component (41) is placed or the thin film (40) is vacuumed formed into. The method continues by partly closing a second part of the mould (25) into the first part of the mould (15) and injecting molten plastic (34) onto the surface of the pre-formed component (41) or thin film (40). The second mould part (25) is then fully closed to force the molten plastic (34) to fill the resultant mould cavity (36). This bonds the molten plastic to either the pre-formed component (41) or the thin film (40) to form the final shape of the moulded component (45). Just prior to the mould parts (15) and (25) closing, a cutting edge (28) abuts against and cuts either the pre-formed component (41) or the thin film (40). This trimming occurs around the periphery of the cutting edge (28). The moulded component (45) is then ejected by opening of the mould parts (15) and (25). This process enables the production of a moulded component (45) with an external covering.
