Patent FR-2476452-A1 (FR)
Title: Brassiere providing good freedom of movement - has bones set in fabric separate from cup construction
Inventor: MOREAU ANDREE
IPC: A41C3/00
Filed: 1980-02-21
Abstract: A brassiere offers greater.freedom of movement to the wearer by means of inserting a piece of fabric in each cup to hold the frames or bones beneath the breasts, but separate from the material of the cup. The fabric insert is folded back and sewn to form a tubular space for the 'bone' reinforcement within the structure of the cup. The bone takes its place naturally in the fold of the breasts, leaving the cup free to follow the form of the breast and the placement of the nipple. Greater comfort is combined with efficient support.

Title: Applying paint film to substrate - by transferring dried paint film from temporary release support using adhesive
IPC: B05D1/28
Filed: 1980-10-20
Abstract: Process for applying a paint film to a surface comprises first applying the paint to a temporary carrier web to which the paint film becomes detachably adhered, drying the paint on the support web, and finally transferring the paint film from the temporary support to the surface to be coated by means of a suitable adhesive. Process can be used with any type of paint, esp. those contg. heavy fillers such as silica or sand, which tend to run on vertical surfaces due to gravity. Paint films can be applied for decorative or protective purposes to a wide variety of substrates and are esp. useful for application to vertical walls of elevators, which need not be taken out of service for the paint to dry as is normally the case.
