Patent FR-3136260-A1 (FR)
Title: Générateur cryogénique d’hydrogène gazeux pressurisé - surpresseur cryogénique
Inventor: SCHULZ Jean-Michel
IPC: F04B15/08
Filed: 2022-06-01
Abstract: La présente invention concerne un générateur cryogénique pour l’alimentation en hydrogène gazeux pressurisé d’un moteur ou d’une pile à combustible. Elle permet d’utiliser ou de récupérer une partie de l’énergie nécessaire à sa liquéfaction. Le dispositif comprend une machine volumétrique capable de comprimer simultanément de l’hydrogène gazeux et de l’hydrogène liquide en utilisant le pourvoir de surcompression de l’évaporation de ce dernier. Lorsque ce pouvoir de surcompression est important et qu’il dépasse le niveau de pression demandé par le système d’injection dans le moteur ou dans la pile à combustible, il convient de détendre le fluide hydrogène gazeux jusqu’à obtenir le niveau de pression demandé. Cette détente fournit une puissance mécanique qui minimise la puissance nécessaire à la compression de l’ensemble, voire suivant les réglages et la quantité d’hydrogène liquide, qui peut la dépasser et fournir de l’énergie à l’extérieur. Le dispositif peut également disposer d’un système d’admission d’une petite quantité d’air pré comprimé pour réaliser un prémélange hydrogène/air voire d’initier une précombustion à faible température pour minimiser la création de NOx lors de la combustion final dans le moteur.

Title: Tapered bent frp pipe - of uniform wall thickness
IPC: B29C41/20
Filed: 1972-08-30
Abstract: A tape or strand or reinforcement, e.g. fibre glass is wound round a tapered mandrel.

Title: Proportioning mixer and distributor for liq. cattle feeds - with special liq. supply arrangements to avoid accumulations
IPC: A01K5/02
Filed: 1973-03-01
Abstract: Mixer is used for the prepn. of mixts. of meal and liqs. in given proportions before they are distributed to the feeding troughs of stock-raising farms. It consists of a proportioning tank connected to a mixing enclosure by an upper and lower pipe which are themselves connected to a pump. A float in the tank is surmounted by a rack, each tooth of which corresponds to the distribution of one litre to the troughs. The required amt. of liq. is measured in the tank and transferred to the mixer through a rotating perforated pipe. The meal is introduced through an opening in the top of the mixer and rotating blades mix it with the liq. The mixture is drawn back into the tank by the pump and then transferred to the distributing pipes. Exact vols. of feedstuffs can be distributed thus avoiding errors when the quantities are based on flow times, as hitherto. The liq. or water is circulated to all parts of the system so that accumulations are avoided and possible sources of contamination removed. In use, the setting of the various valves is conjugated manually or automatically to establish the circuits required for the different phases of the operations.
