Abstract: A latch and linkage arrangement (112) in a nuclear reactor control rod drive mechanism (32) includes a latch (114) having an elongated body (118) with opposite ends (118A,118B) and opposite side edges (118C,118D) and multiple latch teeth (116) defined along one of body side edges between the opposite ends. The arrangement also includes a plurality of links (126,128,130). A first link (126) pivotally connects with the latch body (118) adjacent one end (118A) and is pivotally connected to an electromagnetic armature (86,88) for applying a motive force to the latch body (118) through the first link (126). Second and third links (128,130) are pivotally connected to the latch body (118) and to a support tube (58) in parallel relationship to one another so as to define a parallelogram therewith such that when the motive force is applied to the body (118) via the first link (126) the latch body (118) and thereby the latch teeth (116) undergo curvilinear movement toward and away from a latching position.

Abstract: A method of producing a highly reliable mask ROM and the product produced by the method are disclosed. The method is characterized by comprising the steps of forming low doped source-drains to relax the electric field between the gate electrode and drain, thereby suppressing the creation of hot carriers, and of depositing dielectrics of a predetermined thickness between neighbouring gates to control the projection range of impurities implanted into the source-drain region of the bit into which data is to be written, the thickness of the dielectrics being determined such that the projection range does not exceed the junction depth of the source-drain in order to preclude the formation of parasitically doped layers which cause punch-through across an unwritten transistor.

Title: NO x? SENSOR ASSEMBLY.
Inventor: DALLA BETTA RALPH D
IPC: G01N25/30
Filed: 1991-06-12
Abstract: This invention is a self-contained NOx sensor assembly. It may be used to detect NOx levels in a flowing gas stream such as might be found in an exhaust gas from a combustion process and to produce a measurable electrical output related to the content of NOx measured. The NOx sensor assembly is of a configuration that may be detached from a mounting and replaced. The sensor assembly comprises two sensor elements one of which is made up of a catalyst on a temperature measuring device. The other is a gas stream ambient temperature measuring device. The catalyst is selected and configured so that it selectively reduces NOx and the resulting heat of the reaction raises the temperature of the allied temperature measuring device. The sensor assembly also contains a NOx reductant source. The sensor assembly may be placed in a moving vehicle for measuring NOx levels in its exhaust gas.

De préférence, le séparateur (40) de particules est employé avec un turbomoteur (10) fonctionnant parfois dans un environnement chargé de poussières et de matières particulaires. En général, c'est à un tel environnement que doit faire face un turbomoteur (10) d'hélicoptère, ou de véhicule tout terrain. Le séparateur (40) de particules possède des caractéristiques de guidage des particules et de la poussière, notamment une trajectoire de particules aéro-inertielle, un rebond-limite de particules et un flux de balayage spécialement adapté, permettant d'atteindre une efficacité de séparation des particules et de la poussière égale ou supérieure à celle des meilleurs séparateurs de particules à flux axial classiques. Cette efficacité de séparation des particules est obtenue avec un séparateur (40) de particules à entrée radiale qui est plus petit et plus léger que les dispositifs à écoulement axial et s'incorpore avantageusement dans les structures essentielles d'un turbomoteur.

Abstract: L'invention concerne un dispositif mobile pour automate d'entretien sur un métier à filer ou sur un métier à retordre. L'invention a pour but, lors du roulement de l'automate d'entretien sur des courbes du système de rails de la machine textile, d'améliorer les propriétés de déplacement de celui-ci, en vue d'obtenir un déplacement silencieux et continu de l'automate, tout en évitant les frottements de glissement et les brusques avancées de la roue de roulement. Ce but est atteint, conformément à l'invention, grâce au fait qu'un galet-support (4) se trouvant sur le parcours du rail est monté dans un palier pivotant (3), dont l'axe directeur coïncide avec l'axe vertical médian du galet (4), et en ce que ce palier (3) est relié, par l'intermédiaire d'une traverse (9), à un palier oscillant (2) agencé sur la châssis (1), ladite traverse (9) étant immobilisée sur l'une de ses faces, par une butée fixe (8) et sur l'autre face, par un levier à cliquet oscillant (10).

Abstract: The present invention relates to a positioning device in sewing machines for closing the toe of socks or the like. The device comprises a pair of laminae (2a,2b) which are arranged mutually adjacent so as to define, between them, a passage (3) in which a portion (11) of the sock, which is arranged proximate to the toe of the sock and is thinner at least with respect to a border (10) which delimits this portion on the sock body side, is inserted. The sock is arranged between the laminae so that one free end (12) of the toe to be closed protrudes from one side of the pair of laminae and so that the body (4a) of the sock protrudes from the opposite side. The device comprises tension application means (14a,14b) which can engage the free end of the toe and cooperate with the laminae in order to position the border, which delimits the thinner portion on the sock body side, against the side (23) of the laminae which is directed toward the sock body during the advancement of the sock along the passage.

Abstract: The invention relates to a wiggler having a longitudinal axis (1) and having a vertical axis (2) which intersects said longitudinal axis (1) and is at right angles thereto, which wiggler has two coil arrangements which are aligned at a distance from one another along the vertical axis (2) and essentially in mirror-image symmetry with respect to one another with respect to a centre plane which contains the longitudinal axis (1) and is at right angles to the vertical axis (2). Each coil arrangement has a plurality of essentially flat coils (3, 4, 11), an inner coil (3), which is axially symmetrical with respect to the vertical axis (2), being surrounded by an outer coil (4), which is axially symmetrical with respect to the vertical axis (2). The inner coil (3) advantageously has the shape of a racetrack. The outer coil (4) can be approximately circular-symmetrical. Furthermore, a compensating coil (11) can be allocated to a coil (3, 4) of each coil arrangement, which compensating coil (11) can compensate for the mechanical forces acting directly between mutually corresponding coils (3, 4) of different coil arrangements and thus allows mechanical supporting devices to be displaced from the intermediate space (interspace) between the mutually corresponding coils (3, 4). The wiggler according to the invention is especially qualified for superconducting coils (3, 4, 11), especially for producing a magnetic field between a 4 Tesla and 5 Tesla, and for use in synchrotron radiation sources. <IMAGE>
