Abstract: La présente invention concerne un détecteur de proximité entre une masse métallique (1-2) et un élément sous tension électrique comportant un circuit électrique alimentant un dispositif de sécurité (25) tel que la bobine de commande d'un disjoncteur, le contacteur d'alimentation d'un moteur contrôlant le déplacement de la masse, une alarme auditive ou visuelle ou une mise à la terre d'urgence, ce circuit comportant un élément normalement non conducteur rendu conducteur par l'apparition d'un potentiel sur la masse métallique (1) à protéger ou l'antenne (2). Conformément à l'invention ledit circuit électrique est alimenté par une source autonome d'alimentation en courant continu (6), ledit circuit électrique comportant au moins un élément normalement non conducteur (8) qui est rendu conducteur par l'apparition d'un potentiel entre la masse métallique à protéger et un point à potentiel fixe du circuit électrique.

Abstract: Une cellule de détection de pressions différentielles comprend un seul diaphragme (63, 93, 102) en un matériau friable monté sur des plaques de support (50, 75, 120, 130) placées de côtés opposés du diaphragme (63, 93, 102). Lorsque la pression différentielle en face de la plaque de support (50, 75, 120, 130) est nulle, les surfaces (43C, 77C, 102A, 102C) du diaphragme sont concaves et façonnées de façon à avoir une forme très similaire à celle du diaphragme (63, 93, 102) lorsque celui-ci est fléchi, de sorte que lorsque le diaphragme (63, 93, 102) est soumis à une pression sélectionnée et comprimé contre une des plaques de support (50, 75, 120, 130) dans l'un ou l'autre sens, il (63, 93, 102) a une forme sensiblement plane ou plate et s'appuie complètement sur sa plaque de support (50, 75, 120, 130). Le diaphragme (63, 93, 102) peut être façonné en courbant ou fléchissant sous une pression, puis en aplanissant par meulage la surface (43C, 77C) soumise à la pression. Lorsque l'on enlève la pression, le diaphragme (63, 93, 102) se détend et la surface (43C, 77C, 102A) fléchie et aplanie par meulage acquiert l'exacte forme requise. On peut appliquer le même procédé à l'autre côté (102C) du diaphragme (102) ou on peut joindre deux sections de diaphragme (43, 43; 77, 77).

Abstract: There is disclosed herein a machine for removing coatings from uneven surfaces such as concrete and the like. The machine includes a power system for driving a pair of cutter head assemblies (20,21). The cutter head assemblies are rotated in opposite directions to help stabilize the machine and to throw the cuttings out of the way. Each cutter head assembly has a cutter head (44) with a plurality of peripheral sides or facets (45-52) and cutter bars (56-63) are spring loaded thereon to allow cutting tools (86-93) held by the cutter bars to effectively float on the concrete surface and follow uneven sections of the surface. The cutter head assemblies are mounted on the machine so that they can tilt forward and backward and from side to side to facilitate the cutter head assemblies following uneven surfaces. In one embodiment, a plurality of cutter bars are pivotally mounted on the peripheral faces of each cutter head; in another embodiment cutter pads (136-143) with diamond (146-149) bits are spring loaded and extend from the bottom surface of the cutter head; and in other embodiments, cutter fingers (200, 300) are either pivotally mounted to the peripheral faces of the cutter head or mounted for reciprocating movement in slots formed in the faces.

Title: Injection core for two-component injection moulding.
Inventor: SCHELLENBACH FRANK
IPC: B29C45/14
Filed: 1988-06-03
Abstract: An injection core for two-component injection moulding, in particular of plastic stoppers for bottles and similar containers, solves the problem caused by the fact that injection cores in a single piece can only be moved with difficulty, if at all, a predetermined distance away from the first injected body, because of the design of the latter, in order to create a gap for injecting the second body. The injection core is composed of a first (1) and of a second (2) partial cores. The first partial core can be moved a predetermined distance (A, A') away from the first injected body after injecting the first substance, and the second substance can then be injected in the gap thus obtained in order to form the second injected body.

Abstract: A volume ventilator (10) has a ballon valve type (180, 182) exhalation valve for permitting release of gases to the ambient during exhalation period or when there is excess proximal pressure in the ventilator system. The instantaneous proximal pressure in the ventilator system is sent to a microcomputer controller (38). The pressure in the ballon (180), which is the pilot pressure of the exhalation valve (164), is regulated through a jet venturi type pressure controller (80) by a ball valve (204). The ball valve is controlled by a stepper motor (216) in response to the difference between the instantaneously sensed proximal pressure, and the pilot pressure required to be present in the ballon in accordance with an algorithm, or preselected pilot pressure-versus-time function. Accurate servo control of the flow of respiratory gas to the patient is accomplished by a flow control subsystem (86) which incorporates a flow control valve (90) controlled by a second stepper motor (108).
