Title: Rotary electrical energy generator - in which movement of air through duct drives dynamo
IPC: F03D5/00
Filed: 1975-10-23
Abstract: Air enters the duct (7) through the inlet (2) and drives the air screws (5). The rotation of the air screws (5) drives the dynamos (3). The air then flows out through the outlet (6). Current from the dynamos (5) is used to charge the battery (4). The current from the battery can then be used to rotate the dynamos. Once the dynamos (3) begin to rotate a flow of air is induced through the air-screws which then keeps the air-screws rotating so that the dynamos are driven. This generates a continuous supply of electrical energy. The system is an independent source of energy.

Patent FR-2326039-A1 (FR)
IPC: H01L23/48
Filed: 1976-09-20
Abstract: An improved lead frame is provided for the manufacture of high heat dissipating semiconductor devices having a large heat sink metallic portion exposed with plastic encapsulating material partially disposed thereabout. A semiconductor unit is mounted directly on the heat sink such that high heat dissipation is obtained. The lead frame provides for pairs of metallic heat sink portions joined to a interdigitated center lead frame portion such that the interdigitation of the semiconductor device leads associated with each of the opposed heat sink portions provides for a high density lead frame structure from which a minimum of material must be removed in the fabrication process. The center lead frame portion comprises two parallel interconnecting rails or tie bars which provide a dual function in that they provide a mold stop for subsequent plastic encapsulation fabrication steps while simultaneously providing a support for alignment hole means which provide indexing of the lead frame and associated opposed heat sink portions through various automated manufacturing steps. The use of a composite lead frame structure wherein the metallic heat sink portion is joined to the center lead frame structure allows great versatility in the types of material and the types of fabrication steps used to provide a semiconductor device thus allowing manufacture at greatly reduced cost.

Title: Accumulator lug welding system - dipping webs in lug casting mould electrically heated by brief heat input surge
IPC: H01M50/541
Filed: 1976-12-21
Abstract: Lugs are wleded to the webs of accumulator plates in a mould which is heated by an electric element from below. When the free ends of the plate webs contact the molten lead, produced by a large heat input for a short time, they are fused and can solidify into an integral part with the lugs and terminal pins. This ensures a rapid and firm connection between plate webs and lugs. A reliable accumulator cell can thus be produced from an inexpensive lead alloy with a high melting point.
