Title: Spray gun
IPC: B05B15/02
Filed: 1974-08-02
Abstract: A spray gun is disclosed for use in admixing and spraying, as a homogeneous mixture, two or more chemically reactive fluid components, more especially catalyzed polymerizable resin coating materials such as polyurethanes, epoxides, polyesters and other thermosets, either of the self-foaming or film-forming type. Because of the high rate of reactivity of the fluid components involved, the gun is designed to restrict actual admixture of them to a relatively small region within the gun body located immediately upstream of the spray discharge orifice so that application to the surface occurs as promptly as practical after admixture. Flow rate control and check valve means are provided in the gun for the several fluid components in addition a solvent flush system is also incorporated for purging the gun after use. The flow rate control valves are of special ball design, affording greater mechanical simplification and better sealing maintenance than conventional poppet or needle valves. The check valve means are likewise designed to facilitate gun maintenance by the provision of a unitized cartridge, design, making them easily removable from and replaceable in the gun body and giving easier and more complete access to the interior of the gun in connection with periodic major maintenance servicing of it.
Patent ES-433368-A1 (ES)
Title: Control valve
IPC: F16K39/02
Filed: 1974-12-27
Abstract: A fluid control valve of the pilot operated kind has a main valve comprising a valve seat and valve member. The valve member is moved by piston action in response to fluid pressure in a control chamber. The control chamber may be coupled to the upstream pressure or the downstream pressure to close or open the valve respectively. When the valve is open there is a bleed of fluid through the control chamber via inlet and outlet passages from the upstream side and to the downstream side of the valve respectively. An auxiliary valve is situated in the downstream passage and effects control of the main valve. The auxiliary valve may be an on/off valve or a continuously controllable valve whereby the operating position of the main valve member may be controlled at an intermediate position automatically to limit flow rate.

Title: Liquid-semiconductor junction photocells
IPC: H01M14/00
Filed: 1978-01-04
Abstract: Liquid-semiconductor photocells using chalcogenide semiconductors have been advanced recently to the point where they compete favorably with silicon devices for solar power conversion. However, in common with silicon devices, the semiconductor needs to be a single crystal. This fact makes solar power impractically expensive. According to this invention, the chalcogenide semiconductor is made by anodizing cadmium or bismuth in a sulfide, selenide or telluride electrolyte. The anodized element, when operated photovoltaically in an electrolyte similar to the anodizing solution, produces useful power conversion and is relatively inexpensive.
