Abstract: This invention is directed to the use of a single optical sensor (38) to replace two mechanical sensors (16) in a pen plotter. A light beam (30) is directed through a slot (26) in the plotter's main platen (20). The light beam (30) is detected to provide a sig-nal output. Servo fan motors (14) of the plotter are turned on when the light beam (30) is broken by media (42) placed into the plotter for plotting as one function. A load sequence of the plotter is started only after a start command is input by a user through a control console (36) and the light beam (30) is broken by media (42) placed into the plotter for plotting as a second function.

Abstract: A self-supporting automotive headliner comprises a vapor impervious, polypropylene and wood fiber backing sheet with a corrugated paperboard medium adhered thereto and a layer of fiber glass insulation adhered to the corrugated paperboard medium. The backing sheet and paperboard medium provide the structural strength for the self-supporting headliner panel and the fiber glass insulation gives the headliner panel good sound absorption properties.  When forming the headliner panel, the corrugated paperboard medium is located on the backing sheet which comprises wood and polypropylene fibers and a layer of uncured fiber glass insulation is placed on the corrugated paperboard medium. The resulting laminate is molded under heat causing the polypropylene fibers in the backing sheet to melt and phenolic resin in the fiber glass insulation to cure thereby adhering the laminate together and conforming the laminate to the mold.

Abstract: A thrombectomy system for dissolving a soft fibrinous obstruction, such as a recently formed thrombus, within a patient's vascular system, either in a patent vein or artery or in a prosthetic implant, employing a soft rotating brush for separating and mixing the fibrin of the thrombus while a dissolving agent, e.g. streptokinase or urokinase, is introduced and mixed in and applied to the separated fibrin.      The system includes an introducer catheter adapted to be introduced and advanced through a patient's blood vessels until the distal end is positioned adjacent the soft fibrinous thrombus, the brush attached to an elongated, flexible, rotatable drive shaft having a drive motor attached at its proximal end, the drive shaft and brush passed through the introducer lumen to place the brush in contact with the soft thrombus. The brush has soft, flexible bristles extending outward from the drive shaft distal end, the bristles being sufficiently resilient and dimensioned for enabling compression and passage of the brush out of and back into the distal end of the introducer lumen and effective to mix into then fibrin of the soft thrombus, yet not damage the vessel wall. The dissolving agent is introduced during rotation of the brush either through the introducer catheter lumen or a drive shaft lumen and out exit ports at the distal ends thereof in the region of rotation of the brush for dissolving the soft thrombus as it is contacted by the bristles. Optionally, a balloon catheter or a mesh basket may be coaxially introduced through the drive shaft lumen and placed downstream to restrain fragments and to allow the dissolving agent to complete the dissolution thereof.

Abstract: A vessel with a rotatable turret thereon is moored in a manner that minimizes turret tilt while avoiding the need to maintain precisely concentric upper and lower turret bearings. A mooring structure (152, FIG. 7) is formed by a group of mooring lines (162, 164) such as chains, with the upper ends of the lines coupled to the vessel through a connecting apparatus (154) that comprises a group of arms (166) each connected to a corresponding one of the lines. Each arm is pivotally mounted (at 170) on the turret to hang therefrom, so the arm transmits primarily vertical forces to the turret and so the turret bearing (185) has to support primarily vertical forces. Each arm carries a bearing part (174) that presses horizontally against a vessel lower bearing ring (182) mounted directly on the vessel hull independently of the turret. Substantially the entire horizontal components H of mooring force are transmitted from the arm bearing parts to the lower vessel bearing ring, so the horizontal force components are not transmitted through the turret. As a result,the turret does not tend to tilt, and the vessel lower bearing ring (182) does not have to be mounted precisely concentric with the upper bearing.

Abstract: In order to check a vehicle for sagged coil springs, vertical distances are measured between the axis of each wheel and a predetermined location on the vehicle body, e.g., the underside of the fender. Those measured distances axe compared with established values for that vehicle make and model. To facilitate that measurement a tool is elastically bent arid the ends of the tool are mounted by friction-fit against the inside periphery of a wheel rim. The bent tool forms a convex bulge, the apex of which is aligned with the wheel axis and is disposed in or near a vertical plane in which the measurement is to be made. A reference mark provided at the apex of the bulge facilitates a measurement with a ruled tape measure.

Abstract: The locating of the local centre of rotation of a cylindrical body from outside the body, while the body is rotating upon supporting bearings is carried out using a number of distance-measuring diode lasers mounted upon a movable chassis. Such determination of local centres of rotation can be used in the case of hot kilns to re-align the supporting sets of bearings upon which the kiln is rotatably supported. The integrated triangulation monitoring chassis is located in sequence at respective axial stations located along the kiln, adjacent the supporting bearings, and at each station a simultaneous single set of readings from three diode lasers to the shell surface enables a computer to calculate the location of the centre of rotation relative to the chassis. The location of the chassis, relative to a selected datum, is determined by the use of an integrated total station theodolite, which is repositioned, as required, to enable it to access and locate the chassis. A pair of prism reflectors mounted to the chassis facilitate the action of the theodolite, remote radio control being used to align the respective prisms towards the theodolite, in reflecting relation therewith. With each relocation of the theodolite datum its location relative to the original datum is determined, so that the derived centre distances, as measured by the diode lasers, can be plotted in true relation with a common datum, enabling ready determination of the corrections to the supporting bearings that are necessary, in order to achieve a unified axis of rotation for the kiln.

Granted: 1999-08-10
Abstract: Radiotelephones often are powered by batteries (12). When a radiotelephone is bumped, the battery (12) can lose electrical contact with the radiotelephone. When power is interrupted (40), a timer is started (42). When the power is reapplied (44), the timer is sampled (46) and compared against a predetermined period of time. If the power was interrupted for a short time, then the radiotelephone is turned on (50). If the power was interrupted for a long time, then the radiotelephone stays off (48). The timer in the circuit is implemented as an RC circuit (26) starts to discharge. If the voltage level falls below Vref, the radiotelephone will not turn on when the power is reapplied.

Abstract: La présente invention concerne un procédé de vidange d'un réservoir ayant contenu du gaz liquide, et une installation à cet effet. Après avoir vidangé la plus grande partie du contenu du réservoir, mais avec un reste de gaz sous forme vaporisée, on transfère le contenu résiduel aux fins d'échange de chaleur, directement ou indirectement, avec de l'azote froid. De l'azote est vaporisé et chauffé, puis transféré dans le réservoir, tandis que le gaz résiduel est refroidi et condensé, puis transféré dans un réservoir collecteur. L'installation comprend un système d'échangeurs de chaleur (4, 8; 30, 39) relié à l'arrivée (2) d'azote, et le gaz résiduel est chassé hors du réservoir à vidanges et envoyé à travers le système d'échange de chaleur (4, 8) afin de provoquer la vaporisation et le chauffage de l'azote à transférer dans le réservoir, de telle façon que le gaz résiduel qui en provient se condense. Une cuve de collecte (3) est branchée pour recevoir le gaz résiduel condensé. Afin d'empêcher que le gaz résiduel ne se gèle pendant l'échange de chaleur, on peut utiliser un agent réfrigérant qui provoque la vaporisation et le chauffage de l'azote, et l'employer aussi pour condenser le gaz résiduel sans refroidir ce dernier au-dessous de son point de congélation.
