IPC: B29C51/18
Filed: 1975-11-07
Abstract: A method of removing the residual stamp-out matl. from the body and lid of a container which has been thermoformed, then filled, then sealed with a foil lid, is as follows: during thermoforming, the rim of the deep-drawn sheet constituting the vessel is shaped as a circumferential trough surrounding the top of the vessel, then at the sealing station of the process, the covering foil is sealed only to the upstanding part of this rim, and then these two sheets, i.e., the foil lid and the matl. of the vessel itself are separately cut, in a first step in which the foil constituting the lid is sepd. from the remainder of the sheet, while in the second step the container is punched out from its sheet in the depression or trough immediately surrounding the sealed joint. The two different matl. residues are then separately removed. Pref. the covering foil is sealed only to those annular edges which are inside the surrounding trough and the two different sheets of matl. are punched out and pulled away in two separate stages of the process, the covering foil sheet being removed upwards, and the thermoforming sheet being removed downwards. Completely separate removal of the matl. with min. wastage is achieved, without the difficulty caused by damage to the thin foil lid (e.g., of aluminium) due to it being removed in a combined operation with the plastics sheet of the vessel.

Title: Production of coloured effects on textile materials esp. silk - by adding sodium thiosulphate soln. to dyed material
Inventor: DELHOMMEAU MARTINE
IPC: D06P5/15
Filed: 1976-11-04
Abstract: Coloured effects are obtd. on textile materials, esp. silk, by application to dyed material of Na thiosulphate in the desired design. It is applied as a satd. aq. soln. by means of a paint-brush to a dyed material that is still wet. The method produces a feather-like effect on dark materials and a moire effect on dark- or pastel-coloured materials. It is much more effective than previous processes involving progressive addn. of alcohol in the colourant itself, applicn. of coarse salt, or use of paraffin, since it gives regular degradation of the colour and is susceptible to fine control. The application of gutta-percha, obtd. from latex, dild. with 'essence F', by means of a paper cone to the treated material enables white lines to be added to the effects obtd. with Na thiosulphate.
