Title: Regulateur de pression de gaz equipe d'un organe de coupure haute et basse pression
IPC: G05D16/06
Filed: 1977-01-20
Abstract: L'invention concerne une soupape de sécurité pour régulateur de pression. La soupape de sécurité améliorée coupe entièrement l'afflux de gaz depuis l'admission jusqu'à l'émission du régulateur lorsque la pression du gaz descend au-dessous d'une valeur prédéterminée. La soupape de sûreté reste dans l'état coupé même après que des états de pression acceptable sont rétablis. On utilise un organe par lequel le régulateur ne peut pas être réactivé après avoir été coupé par suite d'états de basse pression excessive, sauf par une personne détenant des outils et sachant comment et où les utiliser après avoir vérifié tous les brûleurs et autres émissions de gaz pour s'assurer qu'ils sont tous fermés. On évite les risques d'asphyxie ou d'explosion en cas de baisse de pression anormale.

Title: Oil cooler for electric locomotives - has heat dissipating fins attached to tubes by collars with indentations
IPC: F28F1/30
Filed: 1977-04-13
Abstract: The cooler has a series of parallel tubes (1) through which oil circulates. Circular fins (2) are attached to each tube to increase the heat dissipating surface. Each fin has a cylindrical collar (3) projecting below it by means of which it fits round the tube. This collar which has a large number of small circular indentations (4) in it, is attached to the tube by adhesive. The indentations in the collar make firm metal to metal contact with the tube whilst the adhesive fills the space between them. This construction gives a firm adhesive bond between the fin with its collar and the tube and at the same time give a metal to metal contact for good heat transfer.

Title: Quadraphonic recording system with encoder - converts monophonic signal by filtering into four frequency bands
IPC: H04S5/00
Filed: 1977-05-02
Abstract: A quadrophonic recording system is used to process a monophonic signal in the audible frequency spectrum. The system comprises a processing circuit consisting of four independent circuits. These circuits enable the selection of four sub frequencies within the audible frequency spectrum. The four sub frequencies are regulable in bandwidth, band centre frequency and intensity. The figure bands may concide with frequency response ranges of a number of musical instruments and the range of the human voice. These can be divided for example into a bass band, two mid range bands and a treble band by suitable selection of the sub circuit control.

Title: Granular material classifier control - uses level difference to regulate pulsation of piston acting on liq. carrier medium
Inventor: VRIGNAUD GEORGES
IPC: B03B5/24
Filed: 1977-11-04
Abstract: The control system regulates the works of a granular material separator with pneumatic piston which pulsates a liquid medium. It uses the difference between the maximum and minimum levels in the piston section and a level in the feed system to control admission of air to the piston and adjust the output of havey parts. Exhaust of air from the piston chamber takes place a little time after the liquid reaches its lowest level. This delay is a function of the difference between the low level and the low level of the supply.

Title: Pressure hose non-return valve - has plunger opening passage under back pressure in opposition to spring
IPC: F16K17/30
Filed: 1978-03-07
Abstract: The no-loss non return valve prevents leakage of a medium under pressure in the event of hose fracture downstream of it. It has a plunger (7) movable in a cylinder in opposition to a pressure spring (8) and held in opposition to the spring in a rear position by back-pressure, in which position it leaves a main flow passage free (3) in the valve. On cessation of back-pressure, the spring thrusts the plunger forward and shuts this passage off. There can also be an auxiliary passage (18, 19) to produce a back-pressure acting on the plunger when the main one is shut off, and formed by drillings and an adjusting screw to vary the cross-section.
