Abstract: A heat exchanger comprises a shell having a first inlet and a first outlet for a first fluid (H) and a second inlet and a second outlet for a second fluid (C), and a screw element. The screw element has a core and first and second nested helical flights mounted to the core. The helical flights define first and second helical fluid passages along the shell. The first fluid passage is in fluid communication with the first inlet and the first outlet and the second fluid passage is in fluid communication with the second inlet and the second outlet. The heat exchanger further comprises a plurality of tubes mounted between adjacent turns of the first and second helical flights and extending across the fluid flow passage formed between the helical flights for conducting the first and or second fluid.

Abstract: An actuator release mechanism comprising a longitudinal member, e.g. a piston, which is moveable axially to permit or prevent axial movement of the lock bolt and hence deployment of the actuator. Movement of the piston is due to the force of the lock bolt, under a spring force, on the one hand, and to the position and force of a linkage assembly on the other hand. The linkage assembly comprises a first link fixed, at one end, e.g. by means of a piston lock pin, to the piston and fixed at a pivot point to a second link. The second link is fixed to a rotational drive means, here a rotary solenoid or stepper motor, so as to rotate about a centre of rotation.
