Title: Microcondensers for miniature low voltage circuits - with dielectric cores of super imposed monomolecular layer coatings
Inventor: BRUNET MICHEL
IPC: H01G4/14
Filed: 1974-07-15
Abstract: Electrical condensers for low voltage applications and comprising a layer of dielectric matl. made of oriented, polar organic matl. sandwiched between thin metallic layers and supported on a strip of flexible tape where the dielectric layer is build up by superposition of a series of continuous monomolecular layer deposits, pref. involving 3-25 such monomolecular layers.

Title: Optical coupling block used with light guides - is used for transmission or reception of optical signals to or from any station and has internally reflecting walls
Inventor: HAWKES THADDEUS
IPC: H04B10/272
Filed: 1975-01-14
Abstract: Images from a number of optical emitters are transmitted via light guides (14) to the end face of an optical coupling block (12). This block consists for example of some optically transparent material in the form of a cylinder with internally reflecting walls. Thus the image from any one of the light guides is available from any location on the opposite end face of the block. Light guides in contact with this end face transmit the image to the optical receivers. Thus a 'subscriber' at any station can transmit an image to any one or all of the other stations or receive an image from any one station.

Title: Securing tapes around articles - by pushing articles through straps and joining free ends of straps
IPC: B65B13/02
Filed: 1975-04-07
Abstract: Tapes, which may be metal or reinforced plastics, are applied to an article, which might be a stack of individual articles, by pushing the article through joined tapes extending between pairs of supply reels to deform the tapes into a U-shape round the article. The rearwardly projecting arms of the U are pushed by tape strainers behind the articles where they are cut. The ends of the arms are glued together to secure the package and the ends of the tapes projecting from the reels are also glued to form a barrier to the next article passing between the reels. Each tape strainer includes a member having a pair of clamping surfaces which clamp the tape in two spaced regions, the tape being cut between the regions. Movement of the members towards one another causes the cut ends of the tapes to be brought together where they are glued by glue forced through one of the members.

Title: Mfr. of plastic carrier bags with independent reinforcing handles - simplified by not cutting the bag until the first handle piece is in place
IPC: B31B50/83
Filed: 1975-12-02
Abstract: Each side of the bag is held between two flat, rectangular handle pieces, both with cut-outs for the fingers, and one with a bar stretching along the upper edge of the bag. In the original conception, holes, corresponding to the cut-outs in the handles, were to be cut in the bag before assembly began; this proved to require an accuracy of fitting which could not be achieved in mass production. It is therefore proposed to attach one of the handle pieces - the one with the bar - to the bag first, and only then to make the cut-out in the bag. The second handle piece is then fitted into position; it has flanges which extend across the cut-out and hide the cut edges.
