Abstract: Case EPC-4509 Canada CLOSURE CAP                  Abstract of the Invention A package for containing a product, e. g., carbonated beverages, capable of producing internal pressure is disclosed.          The package features a cap having an annular top was and an annular sidewall downwardly depending from the top wall and having on its inside surface an inwardly projecting helical thread for cooperation with the threaded neck of the container.          An annular interior wall depends downwardly from the top wall and is displaced radially inward from the sidewall to provide an annular space into which the upper portion of the container neck can nest.  On nesting, the container neck forms, with the inside surface of the top wall or the outside surface of the interior wall, at least one seal.  A concave wall is also provided and is attached at its circumference to the lower end of the interior wall.  The concave wall is flexible for upward flexing in response to the internal pressure whereby the interior wall is pressed outwardly to form a second seal against the inside surface of the container neck when the flexing occurs.          The latter seal increases in fidelity in response to the in-crease in internal container pressure.

Abstract: ABSTRACT OF THE DISCLOSURE An apparatus for manufacturing a slide fastener stringer having a woven stringer tape and a coiled coupling element woven therein, includes a needle loom for weaving the stringer tape of warp and weft threads, a mandrel for extending at an angle to the warp threads, and a rotor assembly to be located alongside of the warp threads for winding a monofilament around the mandrel in a circular path to form the coiled coupling element, which is then woven into the stringer tape by the weft thread.  A means on the rotor assembly guides the monofilament to revolve in a substantially conical orbital path around the mandrel, which is eccentric with the circular path and is located closer to the warp threads than the rotor assembly is, so that the monofilament is kept under substantial-ly uniform tension while revolving in the substantially conical orbital path.

Abstract: ABSTRACT OF THE DISCLOSURE       In an apparatus in which particles which may include biological cells are passed through an optical sensing zone to measure their spatial radiant energy distribution for the pur-pose of identifying and/or characterizing the particles or cells, a structure and method are provided for increasing the usefulness of a geometric configuration of photovoltaic detectors such as a known assembly of generally concentric rings of such detectors usually including some wedge-shaped detectors.  These are pro-vided in a generally planar form and the invention provides structure which captures radiant energy in a flow cell of a par-ticular type before projecting the energy to the detector.  In particular an ellipsoid, paraboloid, hyperboloid or similar reflector which is symmetrical about its optical axis is utiliz-ed first to capture the radiant energy on angles which could include most forward and/or backward angles and all azimuthal angles and then deviating the same to the detector assembly mentioned.  By moving the arrangement or assembly of detectors along the optical axis of the reflector the optimum distance is established for obtaining the greatest amount of information sought.       Although the assembly of photovoltaic detectors may thereafter be left in place, it is preferred to substitute for said assembly a second highly economical deviating or reflecting device capable of capturing the radiant energy which would other-wise have fallen on the sensitive plane of the assembly of photovoltaic detectors and deviating the same along a plurality of different spaced paths to independent photodetecting devices.

Abstract: ABSTRACT           This invention relates to a dead time compensation circuit for a radiation detector using a Geiger-Muller tube.  The Geiger-Muller tube is the most commonly used detector for measuring gamma radiation.          However, they have a restricted linear range which makes it difficult to use them with digital numeric displays.  The highest dose rate that can be measured is limited by the tube dead time, i.e. the interval after the initiation of a pulse during which a subsequent ionizing event does not produce a pulse.  The present invention adds one or more pulses to the display counter when the Geiger-Muller tube provides two or more pulses in a given time interval (t).  The dose rate or count rate is sampled at the beginning of each counting period (T) and the interval t is made proportional to the count rate.  At low count rates, where dead time losses are negligible, no pulses are added.  At high count rates, where t can be several times the tube dead time, counting losses of 50% can be compensated.

Abstract: Abstract of the Disclosure A combined serial priority and parallel priority apparatus and method of operation for use in data processing systems. Each of the parallel priority circuits are interconnected by a common parallel priority bus which carries parallel prioritysignals indicating the priority level of any unit requesting access. If a unit requesting access has a lower priority than indicated on the parallel priority bus, that requesting unit is inhibited from obtaining access. If a requesting unit has higher priority than the signals on the parallel priority bus, that unit in turn causes the priority bus to be switched to the higher priority level.   The serial priority circuits act together with other serial priority circuits within a group of priority circuits set to the same parallel priority. In this configuration, the parallel priority circuits perform a high-order priority determination while the serial priority circuits perform a low-order priority determination. A unit requesting access will be granted access only when its parallel priority is equal to or greater than the parallel priority signal on the parallel priority bus and only when its serial priority is greater than any other unit commonly connected in the serial priority configuration.

Abstract: ROLLER CLAMP FOR DEFINING A FLOW LUMEN IN TUBING                  ABSTRACT OF THE DISCLOSURE       A two piece roller clamp is disclosed for regulating the fluid flow rate through plastic tubing (16) by defining the size of the tubing lumen.  The clamp includes a U-shaped body (10) with a base (12) and two side walls (11) and a longitudinally movable roller (13) mounted in tracks (15) formed in the side walls.  The roller (13)  is biased against a roller bearing surface (22) running along the length of the base.  Adjacent to the roller bearing surface (22) is a tube compression slot (30) having a lower wall (32) uniformly spaced below the roller.  A channel (35) of varying cross-section is provided in the lower wall (32) of the tube compression slot.  The roller (13) exerts a uniform, but minimal force on the tubing compressing it against the lower wall (32) of the slot (30) permitting the formation of a lumen defined by the contours of the channel (35).   The slot is dimensioned vertically to provide for the minimal compression force by the roller and is di-mensioned horizontally to confine the entire compressed cross-section of tubing (16) without excess space thereby conforming the tubing to the contours of the channel (35) to regulate the lumen size.  A uniform compression force is maintained during longitudinal movement of the roller (13) by the roller bearing surfaces (22) which prevent perpendicular movement of the roller towards the slot.

Speech synthesizing arrangement for use in both voice-excited channel and formant vocoders. To derive an excitation signal from a base-band, signal distortion networks are used in these vocoders. Simple distortion networks have the drawback that the natural sound of the reproduced speech signals leaves much to be desired for. Networks which give a better guarantee for a more natural speech reproductive have the drawback that they are of a rather complicated design. According to the invention, an improved natural sound of the reproduced speech is obtained, using simple networks, by generating separate excitation signals for different frequency ranges by means of at least two separate distortion networks.

Abstract: Abstract of the Disclosure A coded video signal transmitting and receiving system comprises in combination a coding apparatus using a plurality of prediction functions and provided for a transmitter, a decoding apparatus provided for a receiver, and a coded signal transmission path, whereby a coded video signal transmitted from the coding apparatus via the transmission path is received at the decoding apparatus and decoded thereby.  In the coding apparatus, from a video signal received in time series, tow-dimensional blocks each consisting of a plurality of picture elements which extend over a plurality of scanning lines are formed, and the video signal is delivered out in a different sequence from that of the input time series.  A predictive error value per block with respect to arbitrary one of the plurality of prediction functions associated with each block is generated, and a prediction function to generate a subsequent prediction error value is designated by use of part or all of prediction error values.  An optimum prediction function selected from prediction functions is determined after a predetermined time has elapsed to generate prediction signals for picture elements in the two-dimensional block sequentially in accordance with the optimum prediction function.  In coding the input video signal, at least a signal representative of the optimum prediction function and the prediction error signal are compressed and transmitted via the transmission path to the decoding apparatus in which the compressed code signal is expanded for decoding.

Abstract: BEVERAGE BOTTLING METHOD ABSTRACT A beverage-bottling method for non carbonated beverages. An inert gas, other than carbon dioxide, such as nitrogen, is injected into a non-carbonated beverage prior to filling a container. Inert gas is permitted to escape from the beverage in the filled container before sealing the container. The amount of gas released is sufficient to strip dissolved oxygen from the beverage and then purge air from the headspace of the container. Sufficient gas is re-tained in the beverage to exert a superatmospheric pressure after the container is sealed. The reduc-tion in oxygen content of the headspace is superior to that achieved with using a stream of nitrogen purging gas into the headspace, while dissolved oxygen is substantially reduced and internal con-tainer pressure is increased, the latter being a distinct advantage in containers made of flexible material such as sheet metal and plastic.

Abstract: METHOD AND APPARATUS FOR INSTANTANEOUS BAND    RATIOING IN A REFLECTANCE RADIOMETER                  ABSTRACT OF THE DISCLOSURE         A hand-held instrument is provided to compare information from selected infrared and visible bands in the 0.4 to 2.5 micrometer range, to perform ratioing via a dividing circuit (17) and to directly read out, via a display system (18), ratio values in a continuous digital display.  The dual-beam, ratioing radiometer contains two optical trains (10, 12), each having two repeater lenses (L1a, L1b and L2a, L2b) and a cooled lead sulfide detector (D1, D2).  One of the trains (10) is pivotal to facilitate measurements at distances ranging from about 1 meter to infinity.  The optical trains are intersected by a set of two coaxially-mounted filter wheels (F1, F2), each containing up to five interference filters and slits to pass radiation filtered by the other.  Filters with band passes as narrow as 0.01 micrometer are used in the region 0.4 to 2.5 micrometers.  The total time for a calibration and measurement is only a few seconds.  It is known from previous field studies using prior art devices, that materials, e.g., clay minerals, and carbonate minerals such as limestone, have unique spectral properties in the 2.0 to 2.5 micrometer region.  Using properly chosen spectral filters, and ratioing the signals to remove the effect of topography on the brightness measured, the instrument can be used for real-time analysis of reflecting materials in the field.  Other materials in the broader range of 0.4 to 2.5 micrometers (and even beyond) could be similarly identified once the reflectance spectrum of the material is established by any means.

Abstract: ABSTRACT     A cast-iron pipe having an end socket is rotated about its axis by a driven first roller applied against the outside of the socket and a driven second roller applied against the inside of the socket and pressing the latter against the first roller.  The rollers car. be rotated at differing speeds, and as the socket revolves they rub off or crush burrs or other irregularities on the outside and inside of the socket.  A cutting tool on a pivoted lever arm is applied by motor power to an outer face of an end flange of the rotating socket to trim burrs therefrom.  The second roller supported on an articulated arrangement can be swung into and out of the socket by operation of a first hydraulic jack.  Another hydraulic jack arrangement presses the second roller against the inside of the socket and increases the pressure suddenly when the roller encounters a large irregularity and decreases the pressure to normal when that irregularity has passed the roller.
