Patent FR-2576228-A1 (FR)
Inventor: MARCON CHARLES
IPC: B21D17/04
Filed: 1985-01-23
Abstract: The process according to the invention relates to the production of grooves such as helical threads on the wall of tubes composed of ductile or plastic materials without removal of matter. It involves using a knurling tool (11) of radius (R1) which is freely rotatable about an axis (X3). This axis covers, in the direction indicated by the arrow F2, a determined closed curve (12) which, in the figure, is a circumference of radius (R2) and of axis (X4). The enveloping curve of the path of the shaping edge (15) of the knurling tool has a region of intersection (13) with the wall of revolution (10) of axis (X2). The diameter of the knurling tool is greater than the diameter of the circumference (12). A helical thread is obtained by moving the wall of revolution (10) in relative manner along its axis (X2) relative to the knurling tool (11).

Patent FR-2577970-A1 (FR)
Title: Combination safety lock and method of opening the lock
IPC: E05B37/12
Filed: 1985-02-26
Abstract: The lock comprises coding means 2, 3 and bolt means 6, 7 movable in translational motion over a predetermined return stroke L1 + L2 after the unscrambling of the coding means for the purpose of opening the lock. It is characterised by means 72 for stopping the bolt means 6, 7 in an intermediate position L1 of the return stroke after the unscrambling of the coding means and by means 8 for both preventing a return of the bolt means 6, 7, when the coding means 2, 3 are scrambled and the lock is completely closed, and allowing an end-of-stroke return L2 of the bolt means 6, 7 after a scrambling of the coding means when the bolt means are substantially in the intermediate position. In the intermediate position, the slight return of the bolt means does not make it possible to open the lock, with the result that a scrambling of the coding means is obligatory before any opening of the lock.

Patent FR-2592191-A1 (FR)
Title: Non-linear temperature servo-control method
IPC: G05D23/19
Filed: 1985-12-23
Abstract: In order to control, for example, ten radiators, the device consists of ten measuring stages 1.2.3.4., deriving voltages which are proportional to the heating needs, which are next compared by 5 with staircase ramps generated by 6. The result of this comparison is then applied to the power interface 9 directly driving the load 10. The ten generators 6 are periodically reset to zero by a decimal counter 7, synchronised and put into phase with the mains by the clock 8. When the temperatures of all the various rooms become close to those desired, each radiator is no longer controlled except during one period in ten, and they are all offset with respect to one another by one period. The total consumption becomes constant, and close to Ptot/10. This device applies in particular to electrical heating by resistive elements.

Patent FR-2598073-A1 (FR)
Inventor: MESTAS JEAN-LOUIS
IPC: G10K11/00
Filed: 1986-04-30
Abstract: The invention relates to a device for positioning an exploratory probe in space, for example an ultrasonic probe. This device comprises an essentially rigid arm (20) whose first end (21) is articulated relative to a support holder (10) by two perpendicular articulation spindles (24, 26) and the exploratory probe (2) is mounted on a support element (30) connected to the second end (22) of the arm by at least two articulation spindles (32, 34). The support element (30) of the exploratory probe is connected to the second end (22) of the arm by means of a set of four articulation spindles (32, 34, 36, 38) which are successively disposed perpendicular to each other and in space in such a manner as to occupy a limited volume in the immediate vicinity of the exploratory probe. This device thus offers an ability for unlimited positioning in space of the exploratory probe within a space or volume which is limited or confined, which constitutes an essential technical advantage for locating targets such as concretions, renal or biliary calculi with a view to their destruction.

Title: Support for an optical-fibre storage cassette
Inventor: FORITE ROGER JEAN-MARIE
IPC: G02B6/44
Filed: 1986-06-25
Abstract: This support makes it easier to work on the optical connectors of the cassettes which are difficult to access because of the location which they occupy in the bottom part of the distribution frame. The support 1 of the invention comprises two arms 5, 6 which may be housed in the location occupied by the cassette 2 which is to be worked on, after withdrawing the latter from the distribution frame, as well as a plate 7 receiving two locking members 8, 9, the circularly arcuate external edges of which keep the cassette in place by means of a circular collar 11 of its central opening. These locking members 8, 9 can be moved; they may be moved closer to each other 12, 13 in order to reduce the distance separating their circularly arcuate external edges when it is desired to mount the cassette 2 on this support 1 or, on the contrary, in order to release it therefrom. The invention finds application in the videocommunication field.
