Title: Plug disabling device for electrical appliance - has enclosing housing with sprung flap and clasp connected by padlock to prevent plug connection
IPC: H01R13/44
Filed: 1981-02-17
Abstract: The plug cap consists of a rectangular or cylindrical insulating moulded housing in two sections. These may be united using a hinged flap or slot-and-groove arrangement. The sections of the housing are closed together, sealing off the plug prongs, by the spring flap which snaps into the sides of the housing. The housing sections may be separated again by pressing on the sides of the housing at the level of the flap and pulling. The closing action is fastened by a peripheral catch arrangement located at the adjoining edges of the two sections. The interior of the housing contains a series of integral radial semi-rigid blades which hold the plug and cable in position whatever the size of the plug. The housing may be opened and access to the plug restored quickly. The device is suitable for all kinds of domestic or laboratory equipment.
Patent FR-2500492-A1 (FR)
Inventor: DEBOUZIE ALAIN
IPC: C03B37/05
Filed: 1981-02-24
Abstract: The invention relates to a process and apparatus for the manufacture of fibers from attenuable materials, such as glass making materials, by centrifugation. In a process in which the attenuable material is directed onto the peripheral surface of a centrifugation wheel which is enveloped by a gas current produced by a blowing crown, the invention comprises the projecting onto the fibers of a liquid composition from a centrifugation element, the projection being carried out close to the wheel in the form of drops which penetrate and are atomized by the gas current. The apparatus of the invention includes a projection element rotating with the centrifugation wheel for centrifugal delivery of the drops of liquid composition. The invention provides a very uniform treatment of the fibers, particularly by means of liquid binder compositions.
