Patent CA-2139152-A1 (CA)
Title: Water cooled welding torch
Inventor: ZAMUNER FRANK
IPC: B23K9/28
Filed: 1994-12-28
Abstract: The supply of water to the water jackets in the torch is fed through feed and return hoses, clamped to pipe spigots. The spigots are a self-locking-taper fit in a block, and are drawn into the block with a drawring, using bolts. This spigot-to-block connection is highly robust, has good electrical conductivity, and is well-sealed against water leakage. The electrical supply to the arc is fed through two cables, which lie inside the feed and return water hoses.

Abstract: Dans un aménagement intérieur, nous retrouvons des espaces réservés pour des rencontres de personnes qui discutent de différents sujets ou stratégies. Ces espaces sont généralement un bureau (office) qui occupe une certaine superficie dans une organisation spatiale selon les besoins des utilisateurs. Ces besoins en superficie exigent des déboursés importants à chaque fois qu'une entité corporative ou autre modifie sa structure organisationnelle ou doit se relocaliser. Dans la presente invention l'espace est occupé par une base modulaire munie d'un systéme electrique qui lui permet une rotation sur place ayant pour effet une meilleure utilisation d'espace. (Voir en annexe la figure #5). Sur cette base amovible, nous retrouvons des éléments servant de murs. Ces éléments sont egalement amovibles, légers démontables et décoratifs. (Voir plan en annexe). Cette salle rotative modulaire peut se déplaçer en très peu de temps à l'intérieur du local occupé ou dans un autre local. Cette salle rotative modulaire augmentera l'utilisation de pied carré, ce qui contribuera directement à une baisse des coûts locatifs et à une augmentation de la rentabilité.
Patent CA-2141990-A1 (CA)
Inventor: NAKAYAMA SHIGEKATSU
IPC: A61B3/08
Filed: 1995-02-07
Abstract: The present invention provides a rotary disc for use with a phase-contrast haploscope which is compact and small-scaled, provides a high-speed changeover using a single motor without mutually synchronizing driving portions, and is convenient for use, and provides such a phase-contrast haploscope.     A phase-contrast haploscope includes a disc case and left-and right-hand projectors.  Left- and right-hand look-through holes are formed in a front plate in its lower half portion. Left- and right-hand beam emitting holes and left- and right-hand beam incident holes corresponding to the left- and right-hand look-through holes are formed in the front plate and the rear plate, respectively, at desired opposed positions.  A motor driven rotary disc is contained in a rotatable manner in the disc case.  The through holes and project-through holes sweep out respective concentric circular paths of different diameters and pass at a high rotational speed between the left-and right-hand look-through holes and the through window and between left- and right-hand beam emitting holes and left- and right-hand beam incident holes in such a manner as to instantaneously coincide therewith.  The left- and right-hand projectors takes in beams from the left- and right-hand beam incident holes, irradiates the lantern slides with the beams through appropriate beam transmitting means and projects projecting beams having passed through the lantern slides onto the plane of projection.

Title: Fluid-and-Elastomer Device
Inventor: MCGUIRE DENNIS P
IPC: F16F13/08
Filed: 1993-08-19
Abstract: A damping device which provides superior damping stiffness K" has linear damping characteristics as a function of amplitude and for which the temperature sensitivities of stiffnesses K*, K", K' have been minimized. The device includes a first and second fluid-filled chambers (26 and 28) which are interconnected by a passageway (43). The length and diameter of the passageway, as well as the fluid viscosity, are chosen to give the optimum damping characteristics. Further, a plurality of spring loaded pressure relief valves (82) are integrated into the assembly to allow more flow area to open when a threshold pressure is encountered, thereby reducing the internal pressures and dynamic stiffness K* at cold temperatures.

Patent CA-2150060-A1 (CA)
Inventor: BIGGS JOHN T
IPC: H04M3/56
Filed: 1995-05-24
Abstract: Several novel methods are disclosed for implementing a multimedia conference. In connection with a first embodiment, a conference is initiated when the communications link establishment device of a first endpoint device establishes a point-to-point communications link with a second endpoint device over the network. Next, the user of the first or second endpoint device selects an option of setting up a multipoint, multimedia conference by entering a request into the user interface device of the respective endpoint device. The request is forwarded to the first endpoint device endpoint processor which commands the first endpoint device communications link establishment device to establish a communications link with the reservation system. The first endpoint device endpoint processor then issues an information request to the reservation system for a network address (and/or telephone number) and a conference identification number uniquely specifying a given multimedia conference. The reservation system relays this information request to the MMS. The MMS provides the reservation system with the conference identification number and the network address (and/or telephone number). The conference identification number and network address (and/or telephone number) are downloaded from the reservation system processor into the first endpoint device endpoint processor. The conference identification number and network address (and/or telephone number) are stored in endpoint memory, and are also downloaded to the second endpoint device endpoint processor. The point-to-point communications link between the first and second endpoint devices is disconnected. The first and second endpoint device endpoint communications link establishment devices each establish a communications link with the MMS at the network address (and/or telephone number) downloaded into respective endpoint device memories. Multimedia conferences established according to various preferred embodiments disclosed herein are perceived by endpoint device users to be procedurally continuous, such that, once a communications link is established with a given endpoint device, this communications link is perceived to be substantially continuous until such time as the multimedia conference has been fully implemented.

Title: Method for Controlling Feed in Centerless Veneer Lathe and Apparatus for the Same
Inventor: NAKAYA TAKASHI
IPC: B23Q15/02
Filed: 1995-11-06
Abstract: The method of the present invention realizes accurate control of the feed rate in a veneer lathe under a centerless condition and improves the productivity of the veneer lathe.  After spindles (8a) are moved away and disengaged from the axial ends of a log (11), that is, under the centerless condition, the method of the invention controls the feed rate of a knife carriage (9) based on the current rotating speed of the log (11), which is measured by a speed measuring device (7) engaged with the periphery of the log (11).  When a difference between the current rotating speed of the log (11) measured by the speed measuring device (7) and a theoretical rotating speed of the log (11) driven by a peripheral drive system (2) exceeds a preset level, the method of the present invention stops the feeding operation of knife carriage (9) and thereby the veneer peeling operation of the veneer lathe.  This structure effectively prevents the lowered productivity of veneers and keeps the veneers free from obvious or conspicuous traces of engagement with the peripheral drive system or cracks due to the insufficient synchronism of the veneer lathe with a subsequent veneer processing apparatus.

IPC: H04B1/26
Filed: 1994-05-09
Abstract: An electromagnetic detector (1, 100) is designed to locate an object (22, 122) behind a separator.

A transmit antenna (18, 188) transmits the modulated pulses through the separator (24), and a receive antenna (20, 120) receives the signals reflected from the separator (24). The receiver path of the detector (1, 100) includes a sample and hold circuit (26), an AC coupled amplifier (129) which filters out DC bias level shifts in the sample and hold circuit (26), and a rectifier circuit (130) connected to the homodyne oscillator and to the AC coupled amplifier (129), for synchronously rectifying the modulated pulses transmitted over the transmit antenna (18, 118). The homodyne oscillator (102) modulates the signal from the PFR generator (10, 104) with a continuous wave (CW) signal, and the AC coupled amplifier (129) operates with a passband centered on that CW signal.
