Abstract: A frame type container tank (1) comprises a tank (3) located within the framework (2). Fusto-conical bearer plates (25) mount the tank (3) to end frames (9) of the framework (2) and upper and lower longitudinal members (20, 21) join the end frames (9). Four reinforcing plate members (30) at the four lower corners of the framework (2) each comprise a pair of identical spaced apart parallel reinforcing plates (31) which extend between and are secured to the bearer plates (25) and the lower longitudinal members (21). Reinforcing struts (45) extend between the reinforcing plate members (30) and the lower longitudinal members (21). The provision of the reinforcing plate members (30) in combination with the reinforcing struts (45) provide for significant weight reduction in the framework (2) without loss in carrying capacity of the container tank (1).

Abstract: A container tank comprises a tank mounted between a pair of end frames by upper bearer members and lower bearer members. The tank comprises a cylindrical shell closed by end caps. Each upper bearer member comprises a bearer plate of arcuate partly circular transverse cross section which is similar to the cross section of the central shell of the tank. Each bearer plate terminates in a transverse tank engaging edge which is seam welded to the cylindrical shell of the tank and a transverse frame engaging edge which is seam welded to an upper connecting member of the end frames.

Abstract: A temperature controllable tank container comprises a cylindrical tank mounted between front and rear end frames. A refrigerating unit is mounted in the front end frame. An insulating shell is provided around the tank. Side ducts for carrying chilled air from the refrigerating unit are provided in similar locations on each side of the tank for chilling the tank and in turn the contents of the tank. Chilled air is returned to the refrigerating unit through top ducts also provided between the insulating shell and the tank. The side ducts and top ducts are connected by a chamber formed between an end cap of the tank and an end cap of the insulating shell.

Abstract: A neck frame for an opening to a container constructed to ISO specifications. The neck frame comprises a tubular member, a compensating flange and a second flange extending around the tubular member, all cast integrally of stainless steel. A lid is pivotal on mounting brackets cast integrally on the second flange and is secured to the tubular member by eye bolts pivotal in brackets also cast integrally with the second flange.
