Title: Bending thin sheet - using an elastic roller to vary the degree of bending
IPC: B21D5/14
Filed: 1970-06-02
Abstract: The sheet is bent between rollers, one of which is made of supply, elastic material while the other is made of undeformable material.

Title: Open-cell foam from ethylene copolymers - having uniform cell structure and apparent density
IPC: C08J9/14
Filed: 1971-06-29
Abstract: Open-cell foam from ethylene polymers is produced by mixing copolymers of ethylene and vinyl esters and/or esters of unsatd. carboxylic acid (e.g. an ethylene/acrylic acid/tert.-butyl acrylate copolymer) in presence of crosslinking agents (e.g. sulphur), with a low-boiling expanding agent, at temps. above the crystallite m.pt. of the polymer(s) and under a pressure above the vapour pressure of the expanding agent, followed by cooling of the homogeneous mixture to a temp. from 15 degrees C above to 20 degrees C below the crystallite m.pt., and forcing the mixture into a zone of lower pressure e.g. by extrusion. The polymer(s) are crosslinked to a degree of crosslinking such that the elongation at break of the cross-linked polymer is 20-60%  that of the uncrosslinked polymer. The homogeneous mixture is allowed to dwell for >=10 mins. at a temp. from 15 degrees C above to 20 degrees C below the crystallite m.pt. of the polymer, in a zone in which there exists a pressure such that foaming of the mixture is prevented. The products have even cell-structure and density, and are free from shrinkage voids.

Title: Automatic biopsy unit - has turbine with sliding hollow shaft carrying needle in which vacuum is created
IPC: A61B10/00
Filed: 1973-07-13
Abstract: There is an air turbine (16) on a tubular shaft (12) sliding axially and carrying a hollow sampling needle (13). Propulsive devices simultaneously rotate the turbine and cause it to slide axially with the shaft. While this is happening, a vacuum is created inside shaft and needle, in order to retain the sample take, when the shaft has slid for a preset distance, release devices shut off the propulsive devices and return rotor and shaft to their starting point. The operator can replace the vauum inside shaft and needle by excess pressure, in order to expel the sample inside. The turbine has a blade-carrying plate acting as a piston to produce the axial movement.

Title: Contrast compensation system for optical display - uses liquid crystal enabling operation in high ambient light levels
IPC: G02F1/139
Filed: 1973-11-09
Abstract: A filter placed in front of the screen comprises a film of liquid crystal (11) placed between two polarisers (20, 21) with different polarisation directions. A voltage is applied between the film's conducting faces (18, 19) using a voltage source (15) and a switch (14) mounted in series at the terminals of the two faces. The voltage is applied for strong illumination of the screen by ambient light and is not applied when the screen is only feebly illuminated. The filter's transmission factor is low when the voltage is applied and higher when the voltage is not applied. Thus the system provides compensation for variations in contrast between the information on the screen and the bottom of the screen following ambient light variations.

Patent FR-2229690-A1 (FR)
IPC: C07C275/62
Filed: 1974-05-16
Abstract: To reduce the biuret content in urea, either in the molten state or in solution at a concentration from 1.0 to 99.9 %, this urea, molten or in solution, is contacted with an ion exchange resin. It is advantageous to use an extremely strong anionic resin. The process is carried out at temperatures between 0 and 200 DEG C; it can be continuous or discontinuous. The process can be carried out in a column (11) containing a resin bed (12). The column has an outer jacket (14). The implementation of the process does not require alterations to the urea production plant or changes to the parameters of this production.
