Title: Appareil a bobinage sans noyau pour fusible  limitateur de courant
Inventor: FECTEAU GILLES
IPC: H01H69/02
Filed: 1982-03-11
Granted: 1984-08-14
Abstract: L'invention concerne un appareil perfectionné pour la fabrication de fuisibles-limiteurs de courant sans noyau, du type comprenant au moins un élément fusible enroulé en hélice à l'intérieur d'un tube isolant rempli d'un matériau granulaire capable d'absorber l'énergie produite par la coupure d'un courant de défaut. Cet appareil comprend une tête mobile formée de plusieurs tiges filetées symétriquement disposées autour d'un axe central et dont les filets sont spécialement conçus et façonnés pour servir de guide hélicoïdal aux divers éléments fusibles. La rotation de l'ensemble de la tête mobile ou de chacune des tiges filetées est synchronisée de façon appropriée avec le mouvement d'un plateau élévateur qui les supporte. En opération, la rotation de la tête mobile autour de son axe central permet le bobinage des éléments fusibles dans les filets des tiges filetées. Une fois ce bobinage effectué, une translation du plateau élévateur combinée à la rotation de chacune des tiges filetées de la tête mobile dans un rapport précis de rotation permet un auto-désembobinage des éléments fusibles au sein du tube isolant. Ce mouvement d'auto-désembobinage s'effectue en même temps que le tube isolant est rempli en matériau granulaire de façon à ce que les éléments fusibles soient immobilisés au fur et à mesure qu'ils sont désembobinés en hélice dans le tube. Cet appareil est particulièrement intéressant dans la mesure où il permet la fabrication de fusibles-limiteurs de courant sans noyau quelles que soient la forme, les dimensions ou les qualités mécaniques des éléments fusibles. L'invention concerne également une méthode de fabrication de fusibles-limiteur de courant sans noyau à l'aide de l'appareil perfectionné ci-dessus défini.

Abstract: TURNED CORIOLIS ANGULAR RATE MEASURING DEVICE            ABSTRACT OF THE DISCLOSURE             A tuned coriolis, angular rate measuring device includes a substantially hollow, generally annular rotor driven by a high-speed, synchronous spin motor. The motor is made unsymmetrical by mounting within the rotor near its periphery at least a pair of high density masses, the respective masses being located diametrically opposite one another.  The rotor is secured within a gimbal structure which is, in turn, mounted in tuned fashion upon a support housing through a cantilever spring at each end along the gimbal output axis, thereby providing bearingless, frictionless pivots permitting limited gimbal rotation. A pair of piezo-electric crystals is secured at opposite edges of one of the springs for sensing relative angular motion between the gimbal and the housing.  The crystals are electrically paralleled so as to cancel any signals resulting from linear movement between the gimbal and housing.

Abstract: ABSTRACT OF THE DISCLOSURE A latch for a door or cover associated with a wall or enclosure. A movable latch arm on the door or cover is spring biased to engage a projection on the wall or enclosure when the door or cover is closed. A blocking member on the door or cover is biased for movement into the path of movement of the arm to prevent its engagement of the projection. With the door or cover closed, the pro-jection holds the blocking member out of the arm's path. Movement of the arm to disengage the projection and coupled with opening of the door or cover to separate the projection and the blocking member, results in the blocking member blocking the arm. Reclosure of the door or cover results in the blocking member being held out of the path of the arm which automatically re-engages the projection. The arm and the blocking member may be on the wall or enclosure and the projection may be on the door or cover. The latching system may include two or more projections, blocking members and arms, and the latter may be commonly movable. A latching system may also include facilities which prevent insertion of a lock shackle into a locking staple, which passes through the closed door, if the projection (or all pro-jections) is not engaged by the arm (or arms).

Abstract: ABSTRACT     An apparatus and method of sweeping a substantially flat optical plane substantially perpendicular to an incident laser beam is disclosed.  A penta-prism, optical detector and adjustment means are disposed in a housing adapted to be mounted on a rotatable spindle.  When so mounted, the penta-prism is disposed a predetermined distance from the point of intersection of the axis of rotation of the spindle and the axis of a properly oriented laser beam.          The optical detector determines whether the axis of the incident laser beam intersects the point of intersection and the adjustment means translates the incident laser beam until its axis substantially intersects the point of intersection in response to the output of the detector means.  When this is accomplished, the penta-prism will produce a substantially flat optical plane when the housing is rotated on the spindle.

Abstract: TITLE: BRASS PLAQUES          ABSTRACT OF THE DISCLOSURE Brass plaque indicia indicating products are provided according to the present invention which can be economically produced by stamping of brass plate.  Prior to the present invention stamping of brass plate to define brass indicia was not economical relative to forging techniques due to the high amount of scrap brass plate which resulted by the stamping operation.  The present invention recognizes that the scrap produced during this stamping of the indicia can provide a brass plaque having an interior which defines an outline of the indicia and if a background member is secured behind the brass plate this combination defines the desired indicia.  Therefore by stamping of brass indicia and using the remaining scrap to define a further brass plaque which in combination with a background member defines the indicia, the stamping operation becomes very economical relative to a forging operation as two brass products for identifying indicia are produced by the one stamping operation.  Furthermore, it has been found by providing a polished brass surface and a background member of contrasting colour, the visibility of the indicium is greatly increased with decreasing lighting conditions relative to the recognition of the brass indicium itself.  This increased visibility is due to the light reflective nature of the brass plaques and the contrasting colour of the background member which advantageously diffuses light to further enhance the contrast.

Abstract: ABSTRACT OF THE DISCLOSURE     A phase differential determining apparatus generates low frequency output signals from a multiple channel receiver and extracts relative phase angles of the received RF signals therefrom.  The same local oscillator signals, which are phase locked to one of the received RF signals, are utilized for all channels thus preserving the phase difference of the RF signals during the heterodyning process so that phase angle differences between the low frequency output signals is the same as the phase angle differences between the received RF signals.  The relative phase angles are determined at the low frequency output level by phase shifting a low frequency signal from the local oscillator that is phase locked to a reference channel and varying the phase shift applied thereto until the phase difference between this low frequency local oscillator signal and the low frequency output signal of the selected channel is zero.  The phase shift introduced to the low frequency local oscillator signal is equal to the difference in phase between the two RF signals.

Abstract: METHOD OF AN APPARATUS FOR DEEP    DRAWING METAL CONTAINERS               ABSTRACT OF THE DISCLOSURE       An improved method of and apparatus for deep drawing metal containers is disclosed in which flat sheet metal blanks are initially drawn into shallow cups having an open top, a substantially flat bottom wall, a substantially cylindrical sidewall and a curved transition section joining the bottom wall and sidewall.  A redraw sleeve adapted to fit into and support the cups has a first annular clamping surface on its free end contoured and arranged to engage the transition section and the adjacent annular peripheral portion of the bottom wall of a cup.  An annular redraw die is supported for movement from a retracted position spaced from the redraw sleeve to a clamping position cooperating with the redraw sleeve to clamp and hold the cups during redrawing.  The redraw die has a second clamping surface contoured to engage the outer surface of the transition section and the adjacent annular peripheral portion of the bottom wall of a cup supported on the redraw sleeve. One of the clamping surfaces is defined by an annular clamping surface portion on an outer and at least one inner concentric ring member, with the clamping surface portion on the outer ring member being adapted to engage and clamp the transition section.  A male die engages the bottom wall of a cup clamped between the redraw sleeve and redraw die to redraw the clamped cup.  The annular ring members each apply a clamping load to a cup, and preferably, the load applied by the outer ring member is transferred to the inner ring member as the cup is drawn inwardly past the outer ring member.
