Abstract: A method for introduction and removal of smoking or cooking bars into or from a station for the automatic suspension of sausages provided with loops, on a respective bar which is firmly tensioned at one end, proceeds as follows: the bars are initially brought into a ready position one after another in a horizontal position from a place of storage. At this point in each case a bar is firmly tensioned at one end and taken to the station for suspension by a horizontal movement. Finally the loaded bar is grasped from below at both ends and taken in the same direction as before to a waiting station, at which a number of loaded bars are collected for transfer in batches to a smoking or cooking trolley. The method operates with virtually no idle times and is feasible with a single operator who is largely independent of the filling and suspension rhythm.

Abstract: Electrodes of an electro-chemical machining tool are in the form of tubes which carry electrolyte to the surface of the article to be machined. The ends of the tubes adjacent the article are gripped between opposed clamping surfaces (13,14) of a block (10). One of those clamping surfaces 14 has a series of facets (15,16,17) with each facet inclined relative to the adjacent facet. The tubes are gripped between those facets (15,16,17) and serrations (18) in the opposed surface (13). This causes the tubes to have different orientations along the line of those tubes due to the relative inclination of the facets (15,16,17). This enables the tubes to conform to the trailing edge of e.g. a turbine balde.

Abstract: Le système décrit est un système de propulsion additionnelle pour avion composé d'un conduit externe destiné à entourer entièrement chaque moteur à réaction séparé actionnant l'avion, que ce moteur soit du type pur, à dérivation ou à réacteur à double flux. Le conduit contient un agencement d'éléments annulaires variables disposés entre le conduit et le moteur qu'il entoure. Ces éléments variables sont amenés à se déplacer en coopération avec le mouvement axial soit de l'entrée ou de la sortie du conduit externe. L'agencement d'un tel système est conçu pour fonctionner comme une boîte de transmission utilisant la vitesse de l'air, de sorte que les vitesses d'écoulement des masses d'air qui entrent et qui sortent du moteur à réaction sont combinées avec l'écoulement de la masse d'air additionnelle traversant le systèm à conduit. Il s'agit de faire en sorte que la vitesse qui en résulte de l'air sortant du système combiné ne soit pas inférieur à ''V'' (soit la vitesse de l'avion) et ne soit pas supérieur à Vj, soit la vitesse de l'air au niveau des tuyères de propulsion du moteur. La vitesse optimale désirée qui en résulte va dépendre de l'interaction (mélange) des rapports de vitesse d'air respectifs déterminés comme étant les plus appropriés pour permettre d'obtenir l'efficacité de propulsion optimale dans n'importe quelle condition spécifique pendant la mission de vol de l'avion.
