Title: Replacement tool handle
Inventor: CARMIEN JOSEPH ALLEN
IPC: B25G3/26
Filed: 1991-07-05
Granted: 1996-01-09
Abstract: A  replacement tool  handle  for  a  percussive tool includes a high strength, load-bearing rod which is inserted through the eyehole of a tool head from its upper end, a grip which ensheathes a portion of the rod projecting from a lower end of the tool head, and two interlocking members which fasten the grip to the rod. The  rod  includes  a  handle  shaft  capable of passing completely through the eyehole of the tool head, and a shaft retainer located at a first end of the shaft for preventing  an  adjacent end  of the rod  from passing through  the  eyehole.    The  shaft  retainer  forms  a generally frusto-conical slug having an outer surface portion  generally  corresponding to  a portion  of the eyehole,  an  enlarged  portion  which  is  incapable  of passing through the eyehole, and an inner cavity in which the first end of the shaft is secured.  Both the handle shaft and an internal cavity provided the grip have non-circular cross-sections to prevent turning of the  grip  relative  to  the  shaft.   The  interlocking members each include tooth portions which engage one another within the outer periphery of the handle in a manner which denies access to a user, thus ensuring a permanent connection.

Filed: 1991-08-13
Granted: 2002-02-05
Abstract: A sensing edge for causing a closing door to open by actuating a device upon force being applied to the sensing edge. The sensing edge includes a first sheet of resiliently compressible material, a first sheet of electrically conductive material, a layer of non-conductive material, a second sheet of electrically conductive material, a second sheet of resiliently compressible material and an elongate inner core arranged in the recited order. The inner core has a predetermined elastic compressibility which is selected in accordance with the desired sensitivity of the sensing edge, such that the sensitivity of the sensing edge directly corresponds to the elastic compressibility of the inner core. The first and second sheets of flexible, electrically conductive material are spaced apart by the layer of non-conductive material and present opposed portions to each other through an opening in the layer of non-conductive material whereby upon the application of force to the sheath, the inner core compresses until its elastic compressibility is less than the elastic compressibility of said first and second layers of resiliently compressible material and said layer of non-conductive material, whereupon a portion of the first sheet of flexible, electrically conductive material deflects into the opening in the second layer of non-conductive material and into contact with a portion of the second sheet of flexible, electrically conductive material to thereby actuate the device.

Title: Froth washer
Inventor: CHAN EDWARD W
IPC: B03B9/02
Filed: 1991-08-14
Granted: 1995-06-27
Abstract: The washer comprises an open-topped vessel having a tube mounted vertically and centrally therein.   Post-primary bitumen froth is fed to the upper end of the tube.  Pairs of down throw and up throw propellors mounted to rotate in the tube act to shear the froth as it passes down through the tube.  At its lower end, the tube is closed off by a transverse wall.  Slots are formed in the tube side wall to provide an exit.  The sheared mixture thus changes direction as it leaves the tube.   In the vessel chamber, solids and water sink downwardly and are removed as tailings through a bottom outlet.  The sheared aerated bitumen rises and forms a new froth that is recovered in a launder.          Middlings are withdrawn from the chamber and recycled to join the feed.  The product froth is reduced in water and solids relative to the feed froth.

Title: Outline enhancing device
Inventor: OKUMURA NAOJI
IPC: H04N5/208
Filed: 1992-03-24
Granted: 1997-10-14
Abstract: The present invention relates to an outline enhancing device for enhancing an outline of an image formed by a video signal having rising and falling slope portions and a flat portion.  The device includes an enhancing signal producing circuit for producing an enhancing signal having first, second, and third enhancing wave forms which wave lengths are the same as those of three portions of the video signal, respectively.  A delay circuit is provided for delaying the video signal to be synchronized with the enhancing signal.  A subtracter circuit is further provided for subtracting the enhancing signal from the synchronized video signal such that three enhancing wave forms are exactly superimposed on the rising slope, the falling slope and the flat portions, respectively, without any interference to the neighbouring slopes or portion.  As a result of such subtraction, the gradients of the rising and falling slopes are made larger while the flat portion is extended.  Thus, the outline in the video signal is enhanced without producing preshoots or overshoots around the outline.

Title: Stopper-shield combination closure
Inventor: BURNS JAMES A
IPC: B65D51/00
Filed: 1992-04-30
Granted: 1995-12-12
Abstract: A combination closure is provided, particularly for evacuated collection tubes for body fluids such as blood, including an elastomer stopper and plastic cover combination with cooperating locking surfaces spaced   around  the  circumference  thereof.    The stopper includes vertically spaced sealing rings for insertion into the open end of the tube.  Also, the stopper  includes  a  plurality  of  circumferentially spaced   protrusions   and   the   cover   or shield cooperating circumferentially spaced indentations or ports to provide a locking force between the pro-trusions  and  indentations.    As  a  result,   the dimensions of the stopper and the plastic cover are reduced, which in turn reduces the penetration force required  to  insert  a  needle through the  stopper. Moreover,  the  reduced  dimension  of  the  closure allows it to be locked to a bead on the tube whether. plastic or glass,  and the  lesser  overall  diameter allows  the closure on  the  tube to  fit more tube holders or containers during and prior to use.   In addition, the smaller dimension reduces the tendency of the closure to "rock" on the tube.   The closure of  the  invention  includes  means  for  containing liquid  droplets  or  aerosol  when  the  needle  is removed from the stopper.
Patent CA-2068485-C (CA)
Inventor: FORTNER LARRY E
IPC: H01R4/24
Filed: 1992-05-12
Granted: 1995-06-27
Abstract: A length of cordage is terminated by a modular plug which includes a plurality of blade-like terminals. Each terminal includes two spaced tangs which when the terminal is seated in a housing of the plug are caused to engage electrically stranded metallic wire-like elements or tinsel ribbons which are wound helically about a filamentary plastic core of a conductor of a cordage 21. In order to enhance the integrity of the tinsel conductors and their contact with the terminals, the tangs are spaced apart a distance which differs from the lay length of the ribbons. Also, in order to enhance the probability of sustained electrical contact between the tangs and either stranded or tinsel ribbon conductors, the width of the portion each tang in engagement with the electrically conductive portion of an aligned associated conductor as measured in a direction along the length of the conductor is substantially less than in prior art terminals, thereby reducing the amount of the conductive portion of the aligned associated conductor which is penetrated when the terminal is inserted.

Abstract: A disposable video cassette for rotatably mounting a pair of reels for a recording tape in juxtaposition to allow transfer of the tape from one reel to the other as they are rotated in unison when the cassette is operating in a video cassette recorder (VCR) has a housing formed from a position of a singly flat paperboard blank having plural cutouts and fold lines for mounting the reels and accommodating rotation therein, for loading the cassette directly into the VCR. A pair of the cutouts is spaced apart in one side of the housing to expose the respective rotational driving mechanisms of the pair of reels in the housing, for mating with the driving mechanism of the VCR when the cassette is loaded therein. Another position of the blank constitutes an appendage to the housing conforming to the shape of the housing when formed. The appendage has fold lines to enclose the housing therein, to provide an integral mailer for the cassette, and is attached to the housing along an easy-tear fold line to permit ready removal of the mailer when the cassette is to be used in a VCR. The mailer when detached becomes printed material, i.e. a coupon, educational material, pharmaceutical detail material, games, etc.

Title: A method of subtitling motion picture films
Inventor: NACHMANSON SAVELY
IPC: G03C11/02
Filed: 1992-10-07
Granted: 1999-09-07
Abstract: ABSTRACT OF THE DISCLOSURE      A method of subtitling motion picture films in which graphics elements, characters, or texts are added to a motion picture film by means of a laser beam travelling over the zone to be marked of the film, comprises the following two steps: a first step, in which a laser etching operation is performed by applying a laser beam whose speed of displacement over the film lies in the range about 1 cm/s to about 200 cm/s, with its power on the film lying in the range about 100 milliwatts to about 20 watts, and with the ratio V/P of the displacement speed expressed in cm/s divided by the power on the film expressed in watts lying in the range 10 to 30 so as to be high enough for the laser beam to achieve complete transformation of the emulsion in the etched zones by causing the emulsion to be heated, softened, and dislocated, but without totally eliminating the transformed emulsion; and a second step, in which the etched film is subjected to cleaning treatment for cleaning the etched zones so that the particles of emulsion that have been heated and dislocated by the laser beam are eliminated from those zones of the film that have previously been marked by the low power laser beam, thereby causing transparent subtitles to appear.

Title: Color change devices activatable by bending
Inventor: SMITH GARY J
IPC: G09F3/02
Filed: 1991-06-18
Granted: 1996-07-30
Abstract: Color change devices which are capable of undergoing a color change on bending. The devices comprise a flexible sub-strate (24) having a color generating metal (e.g. a valve metal such as Ta or Nb) at at least one surface and an intimately contact-ing optically thin anodic film (30) covering the color generating metal and generating a visible color by light interference and ab-sorption effects. The thin anodic film (30) is produced by anodizing the color generating metal in the presence of an adhesion-reducing agent (e.g. a fluoride) for weakening the normally tenacious bond between the anodic film and the metal. Devices of this kind capable of being activated by bending, as well as by separation of the constituent layers, are produced by carrying out the anodization step in the presence of a particular concentration of the adhesion reducing agent from a narrow range (e.g. 40-350 ppm of fluoride). The devices can be used as tamper evident labels and the like which show evidence of removal of the labels from articles to which they were originally attached as an indication of tampering.

Title: Method for increased resolution in tandem mass spectrometry
Inventor: DOUGLAS DONALD J
IPC: H01J49/42
Filed: 1993-02-23
Granted: 1999-03-16
Abstract: A method is provided of increasing the resolution in a tandem mass spectrometer having a first quadrupole Q1 to select a parent ion,  a second quadrupole Q2 which contains a target gas and forms a collision cell, and a third or analyzing quadrupole Q3 which generates a mass spectrum from daughter ions from Q2.  In the method, the target thickness of the target gas in Q2 is held at least at 1.32 x 10 15 cm-2, preferably at least 3.30 x 10 15 cm-2, and the DC offset voltage between Q2 and Q3 is kept low or zero.  This greatly improves the resolution available in Q3.  Q3 is therefore operated with at least unit resolution, and in some cases with resolution of 1/2 or 1/3 amu, making it possible to resolve isotopes of singly, doubly or triply charged daughter ions.

Title: Detection d'explosifs au moyen de la resonance nucleaire quadripolaire
Inventor: BUESS MICHAEL L
IPC: G01N24/00
Filed: 1992-04-24
Granted: 1999-01-26
Abstract: L'invention est constituée par un système et une méthode de détection d'explosifs et de narcotiques contenant de l'azote par l'examen d'un échantillon (1) par résonance nucléaire quadripolaire qui offrent une sélectivité, une sensibilité et une localisation spatiale améliorées comparativement aux systèmes de détection courants. Comme résultat, on peut détecter des quantités d'explosifs et de narcotiques inférieures au kilogramme même si ceux-ci sont mélangées à des matériaux inoffensifs en utilisant la détection par résonance nucléaire quadripolaire du système et de la méthode de l'invention. De plus, en utilisant une bobine de surface (10), les champs électrique et magnétique s'atténuent très rapidement avec la distance, de sorte qu'une région restreinte peut être explorée et que les personnes peuvent être explorées sans que l'intérieur de leur corps reçoive une quantité substantielle de rayonnement RF. Finalement, en utilisant une séquence d'irradiation à rayonnement intense hors résonance, on peut améliorer le rapport signal sur bruit du signal détecté et obtenir ainsi un signal de détection plus précis avec l'échantillon.
