Title: Regulateur de gaz electronique a volume eleve
Inventor: SULATISKY MICHAEL
IPC: G05D16/20
Filed: 2001-01-31
Abstract: L'invention concerne un régulateur de gaz (14) destiné à la régulation de la pression d'un gaz s'écoulant, à partir d'une source (12) de gaz sous pression, vers un dispositif utilisateur de ce gaz (24). Le régulateur (14) comprend un boîtier (26) et un détendeur (36) monté dans ce boîtier, destiné à régler le débit du gaz s'écoulant d'une entrée (28) sous pression vers une sortie (32) sous une pression déterminée. Le détendeur est réglé par un élément sensible à la pression (40, 44) qui est déplacé par des vannes opérationnelles d'alimentation et de décharge (50) accouplées à une chambre de réglage (46) dudit élément sensible à la pression. Les vannes d'alimentation et de décharge sont mises en action par une commande rapide à électro-aimant (68). La vanne de décharge est mise à l'air libre par la sortie du boîtier à partir de la chambre de réglage qui est maintenue sous une pression élevée. La commande rapide à électro-aimant (68) est actionnée par une unité de commande (18) en vue de modifier, comme on le désire, de manière réglable, la pression de sortie.

Abstract: A golf bag has legs attached to its side which are movable between a retracted position against the side of the bag and an extended position where they act in cooperation with the base of the bag to support the bag at an acute angle with respect to the vertical so that golf clubs carried in the bag are readily accessible. The legs are movable to their extended position by a rod which extends from the legs to the bottom of the bag.  A portion of the base of the bag adjacent to the actuation rod is relieved thereby permitting the bag to be placed vertically on its base without interference from the rod while still allowing the rod to be moved by placing it on the ground and pushing the bag downwardly.

Abstract: A method of constructing a filament support member from a single-piece preformed refractory metal wire having at least one loop protrusion formed in the wire and positioned between the ends of the wire.  A section of glass tubing is positioned over and supported by the loop protrusion with a head portion of the loop extending beyond the section of tubing. Heat is applied to melt the section of tubing to form an insulating bead at the base of said loop protrusion.  The head portion of the loop protrusion is then trimmed to interrupt electrical continuity in the wire and thus electrically isolate the respective ends of the wire.

Title: Process and device for electromagnetically casting metals
Inventor: WEBER JEAN-CLAUDE
IPC: B22D11/01
Filed: 1989-12-18
Abstract: Abstract In a process for electromagnetic casting of round and hollow ingots, in particular such of aluminum and aluminum alloys, the ingot (7) is rotated about its longitudinal axis (x) during casting. This is achieved by way of a rotatable dummy base (6). With that the metal feed and cooling of the ingot is made symmetrical and, as a result, a more uniform shape is obtained and a more uniform cell structure across the ingot cross-section. In order to promote a stronger stirring effect, a stationary stirrer (8) dipping into the molten part of the ingot (7) can be provided attached to the metal inlet system (3).     (figure 1).

Title: System for removal of asbestos material
Inventor: LIVINGSTON JOHN Y
IPC: B65G53/60
Filed: 1990-04-24
Abstract: Abstract of the Disclosure A system for removal of asbestos material comprises a pair of collection and discharge units. Each unit includes a housing, a hopper mounted to the housing,  and  a  slide  gate  valve  or  valves  for selectively sealing and opening the associated hopper. A vacuum line and a collector tube are connected to each hopper.   Suitable valves are installed in the vacuum lines and collector tubes.  By controlling the slide gate valves and the vacuum line and collector tube valves, a vacuum can be created in the hoppers alternately to draw material into a selected hopper.

Title: Addition signal multiplexing apparatus for a television system
IPC: H04N7/00
Filed: 1990-02-05
Abstract: The present invention is ingeniously conceived for a transmission system for a first television signal so as to enable a first television signal of a wide aspect screen to be transmitted in one channel and the trans-mitted television signal to be reproduced on a receiver of a conventional aspect screen.  To this end, a screen dividing circuit      divides a wide aspect screen signal into a center panel signal and side panel signals.  The center panel signal is supplied via a delay circuit      to an adder.       The side panel signals are so allocated as to provide horizontal and vertical signals.  The horizontal side signal is supplied via a horizontal overscan multiplexing circuit to the adder      where it is multiplexed on a hori-zontal overscan area of the center panel signal.  In the vertical overscan multiplexing circuit, the vertical side signal is time compressed and reverse processed for each line to provide it in a continuous form.  The output of a vertical overscan multiplexing circuit is supplied to a switch      where it is time division multiplexed on vertical overscan areas of the center panel signal which is sent from the adder      via a delay circuit    .

Title: Reloading system for pitch error correction data
Inventor: TAKAO SASAKI
IPC: G05B19/401
Filed: 1990-04-24
Abstract: ABSTRACT    A system for reloading pitch error correction data at the time of replacing a movable part constituting part of a mechanical system of a numerically controlled machine tool.  A command to reload the pitch error correction data is preset in a machining program at the time of replacing the movable part.  A numerical control device reads this command.  If a parameter reload command is given (S1), and if it is the pitch error correction data (S2), it is determined whether the movable part is situated at the original position (S3), and the pitch error correction data is automatically reloaded (S4).          Accordingly, the operator is not required to carry out any operation related to the reloading of the pitch error correction data, and thus the machining can be effected with the use of correct pitch error correction data.

Abstract: A method of fabricating multilevel semiconductor wafers including a spin-on glass planarization layer is described.      Prior to sputtering of the interconnect layer and after application of the spin-on glass layers the wafer is exposed to an intense glow discharge in such a way that it is bombarded in at least a partial vacuum with ions and/or electrons and/or photons while at a temperature that is between 400°C and 550°C and that is at least 25°C higher than the temperature to which the wafer is to be subjected during the subsequent sputtering step. In this way undesirable molecules can be desorbed from the spin-on glass layer so that they do not interfere with the subsequent sputtering step.

IPC: A61B5/151
Filed: 1991-04-08
Abstract: The present invention provides an actuator mechanism for sequentially advancing and retracting a lancet needle and includes a drive carriage for advancing and retracting the lancet needle and a hinge structure operatively connected to displace the drive carriage. The hinge structure includes first and second coupled leaf members relatively pivotal between a first position thereof in which the drive carriage is advanced to project and thrust the lancet needle into a tissue penetration position, and the second pivotal position of the leaf members in which the drive carriage is retracted to withdraw the lancet needle from the penetration position. The leaf members can also be pivotal to a third position in which the drive carriage is retracted prior to initiating the advancement so that the first position of the leaf members is pivotally intermediate between the second and third~relative positions thereof. The drive carriage is thus advanced and thereafter retracted for thrusting and then withdrawing the lancet needle in continuous reversal motions thereof. The drive carriage is guided so that the advancement and retraction motions are along a highly accurate linear path.
