Title: Digital code and method of converting it
Inventor: STEPHANE BARBU
IPC: H03M7/16
Filed: 1991-09-20
Abstract: The invention relates to a digital code for data processing, in which each line of the code represents an item of coded digital data. It includes: - a first matrix [(1) (2) (3) 4] consisting of at least two cyclic subcodes each having triangular submatrices, - a second matrix [4, 8, 12, 16] having a number of columns sufficient to discriminate the submatrices of the first matrix, each digital data item being represented by one line of the first matrix and a line of the same rank of the second matrix. A method of data processing by conversion of the said digital code into binary code is obtained by logically combining the data of the first matrix [(1) (2) (2) 4] (low-order bits) and of the second matrix [4, 8, 12, 16] (high-order bits).

Title: Device for plugging a flexible pipe (hose) and method for manufacturing it
Inventor: HENRI HOLTERMANN
IPC: A61M39/28
Filed: 1992-02-28
Abstract: The invention relates mainly to a plugging device, particularly for a bag for medical use. The plugging device according to the present invention includes a cylindrical sleeve tube (1), a deformable support component (11) on the flexible pipe (2) for reducing its internal cross-section for passage of fluid and a ring (5) mounted so that it can rotate on the sleeve tube (1).

Title: Measurement of spot welding characteristics - by effecting the quotient of the voltage measured directly at the terminals of the components to be welded, etc.
Inventor: PAUL LEON
IPC: B23K11/25
Filed: 1992-08-19
Abstract: A method is claimed for measuring a magnitude representative of a physical and/or mechanical characteristic of spot welding, in which each value of this magnitude is calculated by effecting the quotient of the value of a voltage measured directly at the terminals of the components to be welded (4,5) by means of measuring points (11,12) by the value of the intensity of the current crossing the components (4,5) and delivered by means of the welding electrodes (1,2). Methods for regulating at least one welding parameter, notably the welding current, of a welding machine and methods for the non-destructive testing of spot welds during a welding operation are also claimed. A non-destructive testing appts. for spot welding is also claimed and comprises a measuring unit (7) to measure the welding is also claimed and comprises a measuring unit (7) to measure the welding current passing through the welding electrodes (1,2) and the voltage at the terminals of the measuring points (11,12) in contact with the components (4,5) to be spot welded and a control unit (9) connected to the measuring unit (7). Spot welding machines incorporating this apparatus for putting into service these methods of regulation and non-destructive testing are also claimed. USE/ADVANTAGE - Used for regulating spot welding operations and for the non-destructive testing of spot welds during spot welding operations.
