Abstract: A prefilled ampoule-syringe of unitary dose comprises an ampoule being closed at one of its ends, the other end being open. The ampoule further comprises a narrowed zone. A hollow capsule is arranged at top of the opening of the ampoule. This capsule is connected to a movable stopper means comprising a stopper head and a hollow cylindrical member having a radial channel and a peripheral rim. This rim acts as a retention member during the storage and as a piston ring during the injection. In order to avoid the loss of its elasticity, the rim is located within a belt of enlarged diameter downstream from the narrowed zone during the storage.

Abstract: Abstract A transmitter combiner includes a plurality of adjacent square prism filters, each of which shares at least one square wall with another of the filters.  Tuning of the individual square prism filters is accomplished by adjusting the position of tuning rods located in the high electric field region of each cavity.  Tuning of each filter is achieved by rotating a control rod perpendicular to and extending through a rectangular end wall to pivot the tuning rod in that filter.  In one embodiment of the invention, the control rod extends through a conductive tube attached along a square wall of the filter and perpendicular to the rectangular wall.  In another embodiment of the invention, the control rod extends from the center of the rectangular wall and supports the tuning element near the center of the cavity.  Temperature compensation is accomplished by variation in the length of the control rod as a function of temperature to compensate for changes in the dimensions of the cavity with the temperature thereof.  In another embodiment of the invention, a bi-metal element shielded from electromagnetic energy in the cavity by a conductive tube causes pivoting of a small tuning rod.

Abstract: SELF-PIVOTING ROBOTIC GRIPPER TOOL                         Abstract A robotic gripper tool pivots under the force of gravity to orient itself to enable the actuation of a selected gripping surface.  The self-pivoting action is accomplished solely by the force of gravity acting upon the mass distribution of the tool with respect to the pivot axis of the tool.  Several different gripping surfaces are provided on the tool whereby time consuming tool changes are substantially elim-inated.  The gripper tool is pivotally connected to a robotic arm.  By pitching the robotic arm, the self-pivoting tool will be positioned by the gravita-tional force acting upon it.

Abstract: ABSTRACT OF THE DISCLOSURE         Signal transmission apparatus is provided for a communications system having a plurality of transmitters for transmitting information signals over any one of several transmission channels, and further having a plurality of receivers for receiving the information signals over any one of the transmission channels.  In order to establish a selected transmission channel between a particular transmitter and a particular receiver, the transmitter selects an unoccupied transmission channel and transmits thereon a code identifying the receiver using a wide band signal for high speed bit transmission.  When the receiver detects the presence of the identifying code over a particular channel, it first determines that the transmitter is the particular transmitter and, if so, establishes the transmission channel therebetween.  The transmitter confirms that the transmission channel has been established, and then continues to transmit the identifying code repeatedly over the transmission channel using a narrow band signal with a low bit transmission rate.  Both the wide band and narrow band signals containing the identifying code are included within the audio signal transmission band, so that no extra bandwidth is required for transmission of the identifying code.

Abstract: ABSTRACT OF THE DISCLOSURE A metal expansion dowel is made up of an axially elongated cylindrically-shaped extension sleeve and an expansion element formed monolithically with the sleeve.  The expansion sleeve has a leading end and a trailing end.  The sleeve has an opening with the opposite edge surfaces extending in the axial direction converging toward the leading end. The expansion element is located in the opening and is secured to the sleeve by a separable web.  The expansion element is wedge-shaped and narrows in the leading end direction.          An inwardly projecting stop is formed in the expansion element.  When an axial force is directed toward the leading end against the stop, the web is separated from the sleeve and the expansion element is displaced axially toward the leading end of the sleeve moving along the opposite edge surfaces of the opening and widening the sleeve.  Due to the converging arrangement of the opposite edge surfaces of the recess, the dowel has a post-expansion characteristic during subseauent axial loading of the expansion sleeve after it is anchored in place.

Abstract: PHASE LAG ADJUSTMENT   IN ELECTRIC METER. Abstract of the Disclosure A phase lag adjustment in an electric meter includes a single-turn loop of large cross section encircling substantially the entire flux generated in a voltage stator which interacts with the disk of the electric meter.  A variable inductor, in series with the single-turn loop, changes the effective impedance of the single-turn loop thereby adjusting the phase angle of the flux produced by the voltage stator.  The variable inductor consists of a small number of turns of copper having a large cross section within a cylindrical shell made of silicon steel.  Threaded bushings at each end of the cylindrical shell accept an adjusting bolt from either direction to permit adjustment from either end of the variable inductor. The silicon-steel cylindrical shell is clamped directly over connecting tabs of the cylindrical shell without insulation therebetween.  The high resistance of silicon steel can be ignored in parallel with the much lower resistance of the copper turns.

Abstract: ABSTRACT INTERPOLATION FILTER WITH    MOTION COMPENSATION     A video signal interpolation includes a frame interpolation filter (402) which generates from a video input signal (Y) by interpolation from corresponding elements of immediately preceding and following fields, a frame interpolated output signal tending to exhibit motion artefacts.  A second filter (430) provides a line interpolated signal having picture elements spatially and temporally coincident with corresponding elements of the frame interpolated signal and having a suppressed vertical detail component.  A third filter (440) attenuates the vertical detail component of the frame interpolated signal.  An output circuit (461, 450) combines the signals of the three filters to provide a frame interpolated video output signal (Yi) in which the vertical resolution of the video input signal (Yd) is preserved and motion artefacts characteristic of frame interpolation are attenuated. The interpolator of the invention is particularly suitable for providing the required interpolated video signal in progressive scan display systems in which a delayed and time-compressed video signal derived from a video input signal is displayed line-by-line alternatingly with ah interpolated video signal obtained by interpolation from the input signal.

Granted: 1990-07-03
Abstract: ABSTRACT OF THE DISCLOSURE     A touch operated switch for control of electrical lighting, appliances, machinery and equipment which requires non sparking fail-safe operation.  The switch utilizes digital complementary metal oxide semi-conductor technology which requires nearly insignificant standby power and incorporates a unique count down reset circuit which prevents extraneous operation from static discharge, radio frequency (RF) signals or power line transients.          The switch will only respond to the electromagnetic flux generated by the power source that the controlled load is connected to.  All other signals or pulses of differing frequencies are ignored by the switch thereby preventing inadvertent operation.  Due to the limited number of discreet components utilized, the total cost of manufacture will be extremely low and is expected to be less than the present manu-facturing cost of the standard wall-type light switches that this invention will replace.  The switch also simplifies inventory control due to the fact that a single switch type replaces all of the multi-pole mechanical switches currently utilized to provide switching capability from various locations.
