Patent EP-0011329-A1 (EP)
Inventor: MEYER ULRICH
IPC: F17D5/02
Filed: 1979-10-29
Abstract: The process for detecting leaks is capable of reliably monitoring pipelines for leakage losses in the case of uniform or greatly differing flow rates. In this process, liquid and gaseous media in pipelines of any size are to be detected at minimum as well as at maximum flow rates irrespective of the number of tapping points. In the event of leakage, the inflow is to be automatically interrupted immediately and can only be put into operation again at will. The contents of the pipeline are set in pulsating flow by a flow-interval device (1) fitted at the beginning into the pipeline to be monitored, but a pressure-keeping valve (2) mounted at the end of the pipeline to the monitored guarantees a constant minimum pressure in the same, and by a pressure-control device (3) which is fitted into the pipeline to be monitored and checks the contents of the pipeline for a pressure drop during every passive phase, repeatedly occurring at intervals, of the flow for the purpose of immediately interrupting the flow in the event of a pressure drop caused by leakage. The flow-interval device (1) can consist of an electric valve controlled by a timer or of a motor-driven, positively controlled mechanical valve. A manostat (3), a plunger-type valve (Fig. 6) or a diaphragm valve (Fig. 7) can serve as pressure-control and closure member. To restore the uniform flow, a pressure-compensating vessel (22) having a pressure-reducing valve (23) can be arranged downstream of the pressure-keeping valve (2). <IMAGE>

Abstract: Small gauge metal tubing is bent into required configuration by a repeated bend-shift-bend method in which the tubing (1) is advanced intermittently through a bend head (4) which operates to put an incremental bend portion of controlled angular extent into the tubing (1). The method determines the final configuration of the tubing (1) as a function (i) of the number and/or angular extent of the incremental bend portions, and (ii) of the extent of translation of the tubing (1) between successive incremental bend portions. The method also envisages rotation of the tubing (1) for determining the plane of the incremental bends. A bending machine for performing the method comprises a powered carriage (3) movable within a channel track (38) under control of a motor (13) and carrying a lazy-tongs type clamping arrangement (8) which is rotatable by a motor (44) for axially rotating a clamped tube (1) being bent. The carriage (3) moves the clamped tubing intermittently and by controlled amounts through a bending head (4) which comprises a hydraulically operated die and former arrangement wherein the die and former are relatively movable to put an incremental bend portion into that part of the tubing (1) which is engaged with the bending head (4). The bending, translating and rotating movements in the machine can be computer controlled.

Abstract: The invention relates to decorative plaques and emblems, and to methods of making the same. 
     In one embodiment, a decorative emblem (10) is formed by insertion of a decorative foil shape (18) into a preformed bezel (12) and encapsulating and bonding the foil to the bezel with a fluent, curable plastic material (14). After an initial casting of a measured amount (16) of plastic onto the base of the bezel, the foil (18) is inserted and seated. A second cast (20) of plastic forms a cap contiguous with the sides of the bezel and encapsulates the foil and bonds it within the bezel. Upon curing, the plastic cap gives a lens effect to the decorative emblem.

Abstract: Un appareil transmet des signaux video (10) qui produisent des images que l'on peut regarder confortablement comme des images bi-dimensionnelles, mais qui, lorsqu'on les regarde au travers de lunettes speciales, apparaissent comme des images tri-dimensionnelles. Une illusion de relief est creee pour des scenes comprenant un objet mobile en combinant une composante de chrominance d'un champ passe avec la composante de luminance du champ present. En "enregistrant" les objets mobiles des champs passe et present, l'objet de fond (stationnaire) des champs passe et present sont legerement deplace l'un par rapport a l'autre. Ces images projetees apparaissent en couleurs complementaires (CYAN, MAGENTA) et peuvent etre regardees normalement si le deplacement est leger, avec un flou de couleurs (44) irreprochable. Lorsqu'on les regarde au travers de verres filtrants appropries, les images projetees donnent une illusion tri-dimensionnelle.

Abstract: The pocket drum (1) has two coaxial rings, each with twelve cells (23). It advances in steps of 15 DEG  by means of the toothing formed by the indentations (21). A cell (23) of the outer ring and of the inner ring alternately thus appears in a window (26).
