Title: Expansion joint for cryogenic fluid pipes - has bellows and sleeve forming chamber for gas preventing compensation
Inventor: VIRICEL JEAN
IPC: F16L59/21
Filed: 1974-08-28
Abstract: One side (6) of a collar is joined to one pipe (2), its other end (5) to a bellows (3) on the other pipe (1). A second bellows (10) on the collar extends along the first pipe. Surrounding this second bellows is a third bellows (9), attached to the collar and second bellows by flanges (11, 12) to form an annular compensation chamber (8).

Title: Circuit breaker with agent producing gas - has resistor to heat agent to produce gas held at constant temp.
IPC: H01H33/76
Filed: 1974-09-24
Abstract: This circuit-breaker is formed by two cylinders. One contains the main operating contacts and the other houses a sleeve of a material such as polytetrafluoroethylene in a gas-tight case. The sleeve is heated by a resistor which is connected between the fixed main-contact and earth via a pressure switch. When the main contacts separates, a valve system in their housing creates a depression. This includes the gas that is produced by the heated sleeve to enter the housing through an orifice near the contact gap and extinguish the arc. This accommodation of the gas-producing sleeve away from the main contacts avoids contamination and deterioration by copper particles from the arc.

Title: Focussing coil for beam tube electromagnets - is in two parts which are fed from common supply and one part has high impedance and other part has low impedance
Inventor: FAILLON GEORGES
IPC: H01J23/00
Filed: 1975-02-21
Abstract: Focussing coil for electric - magnets and associated with electron beam tubes. The design is intended to overcome the problem of modulation, high field intensity and the need for a common electrical power supply.

The remaining coil has a high impedance and superimposes a variable field to make up that required. The two coils are in parallel and present a nominally constant impedance to the supply. The physical arrangement is such that main and auxiliary coils are alternated along the length of the focussing region, the main coils starting and finishing the sequence.

Title: Spark erosion machining programme control - with programme store for start and end of angular electrode setting for oblique cuts
Inventor: LAVRENTIEV K N
IPC: G05B19/31
Filed: 1975-11-06
Abstract: A programme controller for electro-erosion spark machining to cut workpieces of complicated contours from conductor or semiconductor materials is based on the use of not profiled wire electrodes. The programming carrier receives input storage instructions for the starting and finishing point of any section, requiring an oblique cut, and for the angle to the co-ordinate axis. The oblique sections are then produced automatically. This saves the storage of a multiplicity of instructions on the programme carrier. No complex interpolators are required to cut certain sections at an angle automatically.
