Abstract: A cooling jacket of an electric motor or generator includes a cylindrical inner sleeve, a cylindrical outer sleeve coaxially surrounding the inner sleeve and forming a circular space between the outer sleeve and the inner sleeve, and a passageway extending within the circular space between the outer sleeve and the inner sleeve. The passageway may be a continuous winding path that may extend axially back and forth along the circumference of said inner sleeve. An embodiment of the present invention provides a cooling jacket that is suitable for, but not limited to, applications in the aircraft and aerospace industries, for example in air-conditioning systems. The cooling jacket as in one embodiment of the present invention may be leak proof and water tight, has a compact design, and may be easily assembled and integrated into an electrically driven machine, such as an electrically driven compressor.

Abstract: In accordance with one embodiment of the invention, an imaging element is disclosed comprising:(i) a support; (ii) at least one image forming layer; and (iii) an electrically-conductive layer comprising colloidal vanadium oxide intercalated with a water soluble vinyl-containing polymer. The electrically-conductive layer preferably additionally comprises a film-forming binder, which is distinct from the water soluble vinyl-containing polymer. The water soluble vinyl-containing polymer is preferably poly-N-vinylpyrrolidone, polyvinyl alcohol or an interpolymer thereof. Intercalation of vanadium oxide gels with water-soluble polymeric species in accordance with the present invention results in a vanadium oxide gel having improved solution stability and reduced impact of solution aging on conductivity, which improves manufacturing robustness and enables the use of many polymeric binders which could not be effectively used with conventional vanadium oxide gels in conductive layers of imaging elements.

Abstract: In accordance with one embodiment of the invention, an imaging element is disclosed comprising: (i) a support; (ii) at least one image forming layer; (iii) a transparent magnetic recording layer comprising magnetic particles dispersed in a first film-forming binder; and (iv) an electrically-conductive layer comprising colloidal vanadium oxide intercalated with a water soluble vinyl-containing polymer dispersed in a second film-forming binder. The water soluble vinyl-containing polymer is preferably poly-N-vinylpyrrolidone, polyvinyl alcohol or an interpolymer thereof. Intercalation of colloidal vanadium oxide with water soluble vinyl-containing polymers results in improved stability of coating formulations, and an improved colloidal vanadium oxide which is compatible with a wider selection of polymeric binders and facilitates higher binder:vanadium oxide ratios which can improve adhesion of a transparent magnetic layer.
