Filed: 1979-03-09
Abstract: Le présent micromoteur comporte un rotor en forme de doche comprenant un bobinage 1 et une pièce de support 2 fixée sur l'axe de rotation 8 du moteur. Des parties de conducteurs 3, coudées, comportent des bras orientés axialement 3' formant les segments du collecteur, et des bras 3" disposés radialement et servant à la connexion des fils de sortie 5 respectifs du bobinage 1. Au moins une partie des bras 3" est dégagée au moyen d'une creusuré annulaire 4 de la pièce 2. Les bras radiaux 3 ' sont disposés à des distances angu ires égales et permettent, par leurs surfaces à pouvoir réflecteur élevé par rapport à celui du support 2, de détecter la vitesse de rotation du moteur par l'intermédiaire d'un dispositif électro-optique émetteur-récepteur travaillant en réflexion. L'invention s'applique notamment à des micromoteurs électriques dont la vitesse est détectée par exemple pour réaliser une commande de la vitesse du moteur.

Title: Tank for transporting liquefied gases by sea - incorporates fluid tightness and insulating barriers simply realised, necessitating only small sweeping nitrogen flow
Inventor: GILLES AUDY
IPC: F17C3/04
Filed: 1979-07-27
Abstract: A fluid-tight and thermally insulating tank for the transport by sea of liquefied gases, partic. liquefied natural gases having a high methane content, incorporates two successive fluid-tightness barriers. One, the primary barrier, is in contact with the product contained in the tank. The other, the secondary barrier is disposed between the primary barrier and the bearing structure of the ship. These two fluid-tightness barriers are alternated with two thermally insulating barriers. The secondary insulating barrier is constituted of a cellular material fixed against the structure of the ship. The primary insulating barrier is held elastically against the secondary fluid-tightness barrier. The primary and secondary fluid-thighness barriers are constituted by metal plates welded edge to edge by their raised edges being welded to the two faces of a welding flange. The primary insulating barrier is constituted of rigid sheets realised e.g. in wood between which the welding flanges pass. The cellular material of the secondary insulating barrier carriers grooves in which bands are inserted allowing the fixation of the welding flanges perpendicular to the plane of the cellular material.

Title: Drill-bit for boring holes in ground - incorporates cutting blades which are formed separately, give long life and are easily replaceable
Inventor: ROWLEY DAVID S
IPC: E21B10/04
Filed: 1979-10-25
Abstract: A rotary boring-bit comprises a body, a hard metallic binding, impregnated cutting components and a tixation device. The hard metallic binding is fixed to the body and has a face to be turned towards the bottom of the hole being drilled. The binding is fabricated at a temp. exceeding about 1090 degrees C. It has cavities formed previously and opening in its face. The impregnated cutting components, pref. comprising a mixt. of diamonds and a hard metal bound to one another and formed previously, are placed in the cavities and pass beyond the face so that they drill the lower part of the hole when the bit is rotated. These cutting components are fabricated at below 1040 degrees C. The fixation device pref. comprises a brazing material which fixes these cutting components on the walls of the cavities. During brazing, the segments are fixed to the crown at a temp. below that at which synthetic diamonds can be degraded thermally, e.g. at 760 degrees C. Although natural diamonds can be used for the formation of the impregnated segments, it is advantageous that synthetic diamonds are used because they have a much longer life than natural diamonds during drilling.

Title: Voltage regulator for alternator charging vehicle battery - maintains min. voltage through energising winding allowing operation of failure light
Inventor: VOGELSBERGER MARCEL
IPC: H02P9/30
Filed: 1979-10-29
Abstract: The voltage regulator has an amplifier (4) receiving the battery voltage and a reference voltage (UK) which is output coupled to a power transistor (5) controlling the current through the energising winding (2) of the alternator. A failure indicator with a signal lamp (7) is connected across at least one phase of the alternator.

Title: Alarm system for lift cabin - includes pushbutton switch in cabin initiating alarm signal which is only transmitted if lift doors do not open in specified time
Inventor: QUIGNARD BERNARD
IPC: B66B5/00
Filed: 1980-08-01
Abstract: The alarm system for a lift includes a push-button in the lift cabin, operating switch contacts, arranged to connect two flexible wires linking the lift cabin to the machine room. The two wires are connected to a relay and one battery terminal so that operation of the pushbutton causes the relay switch to close. The battery is continuously charged via a transformer and rectifier. The relay operates one set of contacts controlling an alarm circuit and a further set of contacts which are arranged in a self-latching circuit. The self-latching circuit includes switches controlled by the operation of lift doors so that the alarm signal may continue as long as the doors are closed. The alarm circuit includes a timing device which prevents final transmission until the initial alarm signal has continued for more than a preset time. If any lift doors open within this time, the self-latching circuit is released, and no final alarm signal is transmitted.

Title: Workpiece positioning system for machine tool - comprises optical viewing system on track at side of machine to align mark on workpiece
Inventor: CEBE JEAN-PIERRE
IPC: B23Q16/00
Filed: 1980-10-10
Abstract: The system uses a block of stone carrying an indicator mark is mounted in a waiting position on a machine tool. A positioning system, moves parallel to the machine from one point to another where stones are to be positioned. This system carries a visual positioning element which is mounted on guide rails at the side of the machine. This system is previously adjusted so that the indicator mark will be under the cutting tool as it travels to that working position to cut off slices from the stone. A cam on the positioning system allows the positioning element to be positioned w.r.t. a graduated scale. This action is performed at the waiting positions while the toll performs its cutting operation at another position.
