Abstract: A leakage protection system for a heating, ventilation, and air condition (HVAC) system can comprise: a power source; a louvered assembly including a frame, slats spaced apart vertically within the frame and extending from a first side to a second side of the frame, an actuator rod operably coupled to the slats, and a spring; a solenoid operably coupled to the actuator rod; and a first pressure switch disposed electrically between the power source and the solenoid.

Abstract: A heating assembly for a vehicle, the heating assembly comprising: a fluid conduit for carrying fluid; a heater positioned along the fluid conduit, the heater comprising a heating element configured to heat any fluid within the fluid conduit and a power source configured to supply power to the heating element; and a heat sink positioned upstream of the heating element and thermally coupling the power source to the fluid conduit, such that the fluid receives heat from the power source in use.

Abstract: Apparatus for displaying still images that appear animated to viewers in motion relative to those images includes a backboard, a plurality of images mounted on a backboard, and a slitboard mounted between the backboard and the viewer. As viewers pass by, the slitboard acts like a shutter creating an animation effect. Various backboard and slitboard side profiles, such as, for example, parallel and vertical, parallel and non-vertical, parallel and nonplanar, and nonparallel and nonplanar, can be used to facilitate installation of the apparatus in spatially-constrained environments.

Abstract: Contaminated aqueous alkali wash liquor from the treatment of gases containing hydrogen sulphide and/or hydrogen cyanide is reconstituted by treatment at an elevated temperature in a reducing atmosphere followed by quenching to form reconstituted wash liquor. The contaminated liquor is concentrated, before entering the reducing atmosphere, by direct contact with hot gases derived from the hot reducing atmosphere. Quenching and concentration are carried out by interaction of a gaseous medium with a liquid spray. Generation of the hot reducing atmosphere, reaction of the contaminated liquor with the hot reducing atmosphere, and concentration of the contaminated liquor may be carried out in a single chamber.
