Abstract: Abstract Disclosed is a vehicle exhaust system containing a three-way catalytic converter.  An insulated flexible duct connects the outlet of  the  engine  exhaust manifold with  the  inlet  of  the  three-way catalytic  converter  to  retain  the  exhaust  engine  gases  at a temperature greater than the ignition temperature of the three-way catalyst in the catalytic converter.   The insulated flexible duct is preferably made of an inner flexible metal conduit surrounded by fibrous insulation which in turn is surrounded on the outside by a second flexible metal conduit.   The system is economical, contains no active elements which would require maintenance or could get out of order,  is adaptable to motor vehicles of all types  (especially automobiles, light trucks and vans) including those powered by either gasoline and diesel  engines  and  entirely eliminates the need for expensive and complicated light-off catalysts in the system.

Abstract: Abstract of disclosure.          An arrangement relating to a drainage pipe provided with inlet holes for water, said holes being positioned on the upper half of the drainage pipe and the drainage pipe being fully or partly covered by a jacket or ex-terior plate.  The lower edge or edges of the jacket lies or lie substantially on the same level as the lo-wer edge portion of the drainage pipe.  The jacket may possibly be smooth,   whereas the drainage pipe is corrugated.  The water will then rise in the space bet-ween the jacket and the pipe, which space serves for deposition   of possible particles, and thereafter will enter into the pipe through the holes.  The arrangement may be used for simplified disposition of drainage without particular necessity for draining masses above the arrangement.            Fig. 8

Abstract: ABSTRACT OF THE DISCLOSURE     The method and device for the, electropneumatic testing of the air permeability of filter plugs (F) for filter cigarettes, resides in the fact that at one end of the filter plug (F) there is applied a pneumatic pressure, and the other end of the filter cigarette is connected, through a bore (17) with the atmosphere. The pneumatic pressure applied at the inlet end of the cigarette plug (F) is transformed into an electric test signal (transducer T), and the said signal is compared with an upper alarm threshold and with a higher upper reject threshold (variable resistors 132 and 131 respectively) J as well as with a lower alarm threshold (variable resistor 133) and with an inferior lower reject threshold (variable resistor 134). The test signal emitted upon reaching of the upper or lower alarm threshold promotes the operation of alarm indicators (46, 50) and/or sends a signal for the control of the filter plug producing machine, so as to modify the air permeability of the filter plugs (F), while upon reaching of the upper or lower reject threshold, it causes the rejection of the defective filter plugs.

Abstract: METHOD AND APPARATUS FOR DRYING OBJECTS               ABSTRACT OF THE DISCLOSURE      Objects constituted by a porous web-like material, such as a paper web, a granular material, such as peat, or a solid material such as wood, are dried by placing the same in contiguity with a fine porous liquid suction surface which itself is in liquid communication with a liquid volume with the latter        being in communication with apparatus by which the liquid in the liquid volume is maintained at an  underpressure relative to the pressure of the liquid in the object to be dried so that liquid flows from the object into the fine porous suction surface.  The liquid flow can be enhanced through the application of an over pressure or through the direction of radiation onto the object to be dried.  In one embodiment, the fine porous liquid suction surface comprises the surface of a rotatably mounted cylinder whereby a web-like object, such as a paper web, can be dried as the same is carried on the cylinder surface.

Title: Integrated electro-optic wave guide modulator
Inventor: HOLMAN ROBERT L
IPC: G02F1/03
Filed: 1981-08-20
Granted: 1984-07-24
Abstract: ABSTRACT   An electro-optic wave guide substrate for both intensity modu-lating and continuously deflecting an incident laser beam. A first set of electrodes for intensity modulating the beam include substantially parallel, periodically interdigital conductors affixed to a substrate surface and coupled to a controlled voltage source. A second set of electrodes for beam deflecting have non-parallel conductors affixed to the same substrate and are also coupled to a controlled voltge. By controlling the voltage applied to the second set of electrodes the beam can be continuously deflected through a controlled angle to facet track a rapdily rotating multi-faceted mirror of a raster output scanner. The substrate is fabricated using a new techneque whereby the atmosphere in which the waveguiding surface is diffused is controlled. In particular, the diffusion is done in R heated oxygen environment having an elevated moisture content. The elevated oxygen concentation tends to oxidize impurities in the substrate and the moisture tends to form lattice sites for trapping mobile charge carriers. Both effects reduce the incidence of optical damage in the wave guide caused by the laser beam.

Abstract: ABSTRACT OF THE DISCLOSURE     Flypieces are fed by a conveyor to a sewing station in a sewing machine which is operated by a sensor mounted a spaced distance in front of the sewing station to sew the flypieces to a slide fastener chain.  The linear rate of feed of the flypieces by the conveyor is slower than the linear rate of feed of the flypiece and slide fastener chain through the sewing station by the sewing machine, and operation and termination of the sewing machine in response to the sensor is delayed so that uniform spacing is produced between flypieces sewn on the slide fastener chain.

Abstract: ABSTRACT OF THE DISCLOSURE    A foot pedal operated motor control is provided for controlling the speed of a motor,  The entire motor control circuit is mounted in a foot pedal housing which circuit includes a generally disc shaped potentiometer having a rotatable and a stationary member with the movement, of the rotatable member with respect to the stationary member determining the resistance of the potentiometer which controls the current to a motor whose speed is to be con-trolled. The disc shaped potentiometer has an opening therethrough.  A foot pedal is pivotally mounted on the housing overlying the potentiometer and a helical member extends between the foot pedal on one end thereof and into the opening of the disc shaped potentiometer on the other end thereof.  When the foot pedal is depressed the helical member is moved linearly turning the rotatable member with respect to the stationary member of the disc shaped potentiometer thereby varying the resistance of the potentiometer which controls the current in the motor control circuit in accordance with the movement of the foot pedal.  This control is considerably less expensive than slide type or other rotary type potentiometers.  The motion of the foot pedal translates a half inch of linear motion from a full off to full on position on the rotary potentiometer.  Accordingly, any wear is spread over 270° of available rotation of the potentiometer.  The resistance is varied from 0 to 100,000 ohms providing a wide range of motor control at an inexpensive price.  Expensive couplings, linkages and gearings are not required to translate the linear motion of the pedal into a rotary motion for changing the resistance of the potentiometer.

Abstract: ABSTRACT        Apparatus and method for making fluid mass flow rate measurements using a Coriolis flow meter equipped with analog sensors which measure accelerations, velocity, or position of each side leg of an oscillating U-shaped conduit through which the fluid is passed.  The sensors are so constructed and located as to produce analog signal outputs which accurately correspond to the motion of the respective side legs of the U-shaped conduit. When fluid is flowing through the conduit, a change from coincidence in the time relationship of the sensor signals caused by the Coriolis force induced divergent oscillations of each side leg of the U-shaped conduit is measured in both directions, of oscillation. The fluid mass flow rate is then determined as a function of such time separation of the signals."
