Abstract: A chair has a backrest and a pair of armrests. A pair of support struts for supporting the backrest is connected to a shaft of a base under a seat. The armrest is supported by an arm post. An operating lever is mounted on the upper front end of the arm post. When the backrest is tilted, it is held at a desired angle by pressing up the operating lever.

Abstract: A side plate for a heat exchanger and method for making a heat exchanger is provided. The side plate includes at least one localized contact point that can be bonded to a header of the heat exchanger during assembly of the heat exchanger. The localized contact point separates from the header under relatively low tension applied by the thermal expansion and contraction of the heat exchanger under normal operating conditions, thereby allowing the tubes of the heat exchanger to expand and contract.

Abstract: A multi-fluid heat exchanger having separate fluid flow paths for two fluid streams to be heated or cooled by a third fluid stream includes first and second elongated, parallel tubular headers (10, 12), having opposed ends (14), generally uniformly spaced elongated tube slots (16) in each of the headers (10, 12) with the tube slots (16) in one header (10) facing-and aligned with the tube slots (16) and the other header (12), a plurality of flattened tubes (20) extending between the headers (10, 12) and having ends (22) received in aligned ones of the tube slots (16), one tube slot (24) in each header being unoccupied by any of the flattened tubes (20), the one tube slots (24) being aligned with each other and located at a predetermined location between the ends (14) of the headers (10, 12) and between two groups (A, B) of the flattened tubes (20) so there are two groups of the flattened tubes (20) on each side of the one tube slot (24), a pair of baffles (30) in each header (10, 12) with one on each side of t

Abstract: A multi-fluid heat exchanger and a method of making the same are provided wherein a cut portion is provided in an elongated header of the heat exchanger at a location between a pair of baffles in the elongated header and first and second cores of the heat exchanger. At least a majority of the transverse cross section of the elongated header is removed at the cut portion to allow for relative thermal growth of the first and second cores.

Abstract: A fitting/manifold assembly and method are provided for a heat exchanger. The method includes the steps of providing a manifold (22) including a wall (30) having an aperture (32) therethrough; providing a fitting (24) including a body (42), a nipple (44) extending from the body (42) and having an interior surface (50), and an opening (54) extending through the body (42) to allow access to the interior surface (50); inserting the nipple (44) into the aperture (32) from one side of the wall (30) so that the body (42) of the fitting (24) is on the one side of the wall (30) and a portion (48) of the nipple (44) is on the other side of the wall (30); deforming the interior surface (50) of the nipple (44) with a deforming tool (60, 104) inserted through the opening (54) in the body (42) to enlarge the portion (48) to a shape that restricts retraction of the nipple (44) from the aperture (32).

Abstract: A mount bracket (30) is provided for an elongate manifold (12) of a heat exchanger (10). The manifold (12) has a longitudinal axis (32) and a mount bracket receiving exterior surface (34) extending over at least a portion of the longitudinal length of the manifold (10). The mount bracket (3) includes a body (40) formed from a single piece of material. The body (40) includes a mount tab (42), first and second opposed bands (44,46) each of which have a first end segment (56,60) spaced from a second-end segment (58,62), a first bridge segment (68) connecting the first end segments (56,60) of the first and second bands (44,46), and a second bridge segment (70) connecting the second end segments (58,62) of the first and second bands (44,46). The mount tab (42) is configured to connect the mount bracket (30) to a structure other than the manifold (12). The first and second opposed bands define a manifold receiving opening (50) shaped to nominally conform to the mount bracket receiving exterior surface (34).
