Abstract: L'invention concerne un piston refroidi constitué de plusieurs pièces conçu pour un moteur à combustion interne. Ce piston comprend une pièce supérieure monobloc constituée d'une cavité de combustion et d'une paroi annulaire pourvue d'une partie annulaire, et une pièce inférieure monobloc comportant une jupe de piston en forme de caisse, des moyeux servant à loger l'axe de piston qui relie le piston à la bielle ainsi que des supports de moyeux reliés à la jupe du piston. Un canal de refroidissement est ménagé à travers la pièce supérieure et la pièce inférieure du piston et est délimité par celles-ci en section transversale. L'objectif de l'invention est de réduire la hauteur de compression et d'augmenter la charge thermique lorsque la puissance du moteur augmente, et d'assembler ledit piston sans modifier sa structure. A cet effet, la partie supérieure de piston (1) et la partie inférieure de piston (2) comportent des moyens de support (4, 5, 8, 13, 14) qui comprenent des surfaces d'appui (10a, 10b, 12a, 12b) formant un premier et un second appui (10, 12).

Title: Undersea wellhead connection system between - valve and production string
Inventor: HARBONN JACQUES
IPC: E21B23/12
Filed: 1969-01-17
Abstract: Connection system between an undersea wellhead christmas tree and a production string opens upwards through a main valve, the string being linked to a flow line via a curved side line. A rotary member in a housing between the string and the valve turns round an axis offset to that of the string so that in a first position it connects the flow line to the string and sideline system and in a second it connects the string system to the top opening in the housing via a longways channel included in the rotary member. The housing links to the main valve through its upper orifice. Member and valve are synchronised so that for the first setting of the rotor, the valve is shut, and open in the second setting. Bypasses should be provided to maintain the flow between string and flow line and so draw off production fluid even in the second setting of the rotor.

Title: Sheaning sheets of fabric comprising several - pieces with excessive thickness at the joins
Inventor: RIEDEL DIETER
IPC: D06C13/00
Filed: 1969-12-23
Abstract: A toothed control disc is associated with a receiver roll, with which an impulse emitter interacts to actuate a counter when the detector has recorded a join. At each advance of one step by the toothed disc, the impulse emitter causes the counter, which adds the steps together, to advance by one step. When a set value corresponding to a given path of the sheet has been reached, the counter acts by a tension impulse on a regulating device which enlarges the gap. This tension impulse simultaneously releases another counter which advances by one figure at each advance of one step by the toothed disc and adds the steps together. When a pre-determined value corresponding to the length of the sheet has been achieved, the latter counter acts on the regulating device so that the gap assumes its original width.

Title: Cyanogen prodn by oxidn of hcn
Inventor: HEILOS JOHANNES
IPC: C01C3/00
Filed: 1970-05-08
Abstract: Cyanogen is prepd by the catalytic oxidn of HCN with H2O2 in the presence of cupric bromide, cyanide or nitrate. The reoxidn of cuporus ions is accelerated by the presence of ferric ions, and uncontrolled decompsn of H2O2 is minimised by the use of org. solvents pref. tetramethylene sulphone. Cyanogen is obtained in good yields (ca 97%) practically free of O2 and NO2. Space/time yields are 10 to 100 times those of direct oxidn of HCN with cupric salts alone.

Title: Mixing and pumping ferromagnetic -contg. materials - by generating magnetic fields causing movement of ferromagnetic particles
Inventor: JESSEN JOERN JAN
IPC: B01F13/08
Filed: 1973-08-16
Abstract: Materials which contain ferromagnetic compds. are mixed and transported by subjecting than to the action of magnetic fields. The majority of magnetic field forces influence the mixture and, depending on the viscosity and vol. of the mixt, these are switched on and off according to a predetermined programme on an electric or electronic controller. The forces are created mainly by D.C. but also partly by A.C. so that inversions of polarity essential for good mixing are carried out. The material is demagnetised by A.C. at the end of the operation. Use for plastics mixt., etc. contg. magnetic materials, esp. iron or steel fillers in resins in which small rods, fibres, etc. are used. Gives effective mixing without physical agitations and attendant mechanical problems.
