Patent FR-2000272-A1 (FR)
Title: Cartridge cases with reinforced areas from
IPC: B29C43/00
Filed: 1969-01-09
Abstract: Forming reinforced areas in hollow thermoplastic bodies produced by injection moulding, especially at the mouthpiece of cartridge cases, comprises (a) thickening a defined area of the hollow body with excess of material during injection moulding, (b) holding the thickned area by heating at the desired processing temp., and (c) reducing the thickened area to the desired final size to form the reinforced area by mutual displacement of the matrix parts with a simultaneous increase in the elongation in the plane of the material. The method enables cartridge cases with reinforced mouthpieces to be simply and economically produced by injection moulding thermoplastic material. The method requires less operations than previous methods. The cartridge cases are capable of with standing heavy loads during firing.

Title: Cabin ballast system for cableway - has weights hooked to underside to oppose sway due to wind force
IPC: B61B12/06
Filed: 1973-12-17
Abstract: A winter sports cableway system includes a method of attaching weights to the cabins to counteract the effect of wind which causes the cabins to sway.

Title: Self inflating pressure bag for cushioning - uses gas generated by reaction between two chemicals
IPC: B65D81/05
Filed: 1974-07-05

Filed: 1975-03-19
Abstract: A T-joint design to permit improved drainage of a secondary drain into a main drain has a circular baffle plate covering pref. 2/3 - 5/6 of the diameter of the inflow and outflow pipes. The baffle plate is angled at up to 70 deg. to the mixing chamber wall. Water entering the mixing chamber from the input pipe impinges on the baffle plate and is deflected onto the angled wall of the chamber thus leaving a clear water-free space for the secondary drain to empty into the main drain system. Input and output pipes are fixed eccentrically to the mixing chamber as the secondary drain input.

Title: Insulation layer bridging expanding anchor bolt - has expanding sleeve containing stationary and sliding bodies
IPC: F16B13/06
Filed: 1975-04-22
Abstract: Two or more bodies slide in the axial direction one inside the other, one causing the other to expand in the process. One body cannot move in the axial direction, and the other, sliding one has, at the end furthest from the area where the two expand, an expanding portion contained in a sleeve enclosing both bodies. This causes expansion of the sleeve, which is resilient or perforated in the area where the two bodies expand. The sleeve can have slots accommodating expanding shanks on the bodies it contains, and the free ends of the ribs between the slots can also be expansible by the sliding body.

Patent FR-2280936-A1 (FR)
Inventor: CHAIRES ANNE-MARIE
IPC: G06V30/262
Filed: 1975-06-19
Abstract: A binary reference matrix apparatus is diclosed for verifying input alpha words from a character recognition machine as valid linguistic expressions. The organization of the binary reference matrix is based upon the character transfer function of the character recognition machine. The alphabetic character stream for each word scanned by the character recognition machine, is mapped into a vector representation through the assignment of a unique numeric value for each letter in the alphabet. The vector magnitude and angle so calculated constitute the address data for accessing the binary reference matrix. The point accessed in the matrix will have a binary value of 1 if the scanned word is valid and will have a binary value of 0 if the scanned word is invalid. The organization of the binary reference matrix minimizes the size of the array needed for accurate verification by choosing numerical values for the alphabetic characters in an inverse proportion to the characters read reliability in the character recognition machine, as determined by the empirical measurement of the character recognition machine, character transfer function.
