Title: High sensitivity electromagnetic release for contact-breaker - has coil with spring and permanent magnet to actuate plunger
Inventor: MENTION ANDRE
IPC: H01H71/32
Filed: 1976-01-20
Abstract: A sensitive electromagnetic release is used in low voltage contact breaker. It is robust and insensitive to other effects and does not go out of adjustment. The electromagnetic release has a case (1) made of magnetic material with high magnetic permeability and low remanence. The case (1) has a cylindrical recess (2). The recess (2) has an upper face (3) with a circular opening (4) for a plunger core (5). The recess (2) has a winding (6) which also takes the plunger (5). There is also a high permeability and low remanence material polar piece (8) between the winding (6) and a permanent magnet (9). A ring (7) separates the winding (6) and the polar piece (8). A coil spring (11) is fitted inside the plunger (5) and between its core (5) and the polar piece (8). Release is obtained by extension of the coil spring (11) when the winding (6) is energised and demagnitizes the permanent magnet (9). The plunger (5) then moves away from its polar piece (8).

Patent FR-2345355-A1 (FR)
IPC: B65D33/34
Filed: 1976-03-26
Abstract: Plastic bags with a tamper-proof adhesive seal are made by folding and slitting flexible film longitudinally and covering the slit with adhesive coated tape so that one edge of the tape or the folded film will act as a pull tab on a flap covering the bag mouth. Pairs of continuous and of partial transverse welds are applied to the film, the former to seal the edges of individual bags, the latter to provide tear zones to limit the size of the flap when opening the pack for the first time. The bags are prefilled and sealed at their base. Used are continuous mfg. of bags which can be reused and where tearing provides evidence of prior use. The folding, tape application and weld line patterns are suitable for progressive conversion of continuous film into individual sealed bags automatically.

Title: Wall fitting for supporting fluorescent tube - has safety cover which prevents exposure of electrically live parts and includes end flange to press leaf spring against terminal
IPC: F21V25/04
Filed: 1976-12-24
Abstract: A wall fitting for supporting a fluorescent tube has an outer housing (15) supporting an inner cradle (17). The latter has spring fingers (25) which grip the cylindrical end (12) of the fluorescent tube (13) with a snap action. The electric cable (32) is connected to a leaf spring (28) which makes contact with the terminal (30) on the end of the fluorescent tube. The leaf spring is so designed that its curved end (33) is normally clear of the terminal. When the cover (40) is fitted into the slot of the housing (15), the end flange (42) presses the leaf spring against the terminal to close the electric circuit. This type of light fitting ensures that no electrically live parts are exposed when the cover is removed.

Title: Photoconductive layer deposited on TV tube - is uniformly charged so that subsequently applied charged particles are repelled to fill up pin holes, dust particles etc. (BE 16.8.77)
IPC: G03G5/05
Filed: 1977-02-16
Abstract: A slightly conductive coating (2) is applied to the surface (1) of a c.r.t. and covered with a layer of the photoconductive material (3). This is uniformly charged. At any conductive blemishes e.g a dust particle (4), or a pinhole in the layer (3) the charge leaks away through the first coating (2). A developer containing the same photoconductive material similarly charged is then applied. The charged particles are repelled from the charged areas and driven towards the blemishes, where they adhere. The method may be extended to deal also with non-conductive blemishes, though these are rarer. The surface is charged and exposed to light. The charge remains only on the non-conductive blemishes, which then accept a developer containing the photoconductive material, as before.
