Abstract: APPLIANCE DOOR-LOCKING APPARATUS             ABSTRACT OF THE DISCLOSURE:         Safety-locking apparatus for an appliance door latching mechanism includes a solenoid operated locking member requiring an independent manual operation to un-lock the latching mechanism in order to move the latch from the unlatched to the latched position and vice versa.          A high-current switch is included operable by an actuating member responsive to operation of the door latching mech-anism such that an appliance, such as a pyrolytic type of self-cleaning oven, may not be operable in the heat cleaning process unless and until the door latching mechanism, and thereby the door, are in the latched and locked-closed position.  A cam surface on the switch actuating member serves to operate the high-current switch and also pro-vides mechanical advantage for the forced breaking of the switch contacts should they become welded together.

Abstract: REDUCTION OF DISPERSION IN A MULTIMODE FIBER    WAVEGUIDE WITH CORE INDEX FLUCTUATIONS            Abstract of the Disclosure Step index, multimode fiber waveguides are designed according to the disclosed invention with intentional fluctuations of the refractive index of the fiber core, with the aim of reducing dispersion by deliberately enhancing mode coupling in the fiber and, at the same time, minimizing loss in the fiber due to coupling to radiation modes.  It is shown that, to avoid radiation losses, conditions should be imposed not only on the axial (z) dependence of the core fluctuations, but also on the azimuthal (.PHI.) and radial (r) dependence of the core fluctuations.  Specifically, a selection rule is imposed on the coupling in the fiber by providing the core index fluctuations with an azimuthal dependence governed by a function of the form cos p.PHI. where p is an integer equal to or greater than one.  Coupling for a mode of an azimuthal mode number ? is thereby limited by the selection rule .DELTA.?=?p.  Additionally, by limiting the location of the index fluctuations to a region below a certain maximum radius rmax in the core, coupling to modes with large azimuthal mode numbers ? is avoided, and power loss via coupling to radiation modes is held to a minimum.                             - i -

Abstract: ABSTRACT OF THE DISCLOSURE:          The device for the upright maintenance of the body of the harvester-thresher has a pendulum that achieves the continuous variation of the speed of the bringing back movement of the body of the harvester-thresher.,  The pendulum conveys the angular va-riations of the body of the machine to a flow controller of rotary or linear type:  the flow controller commands an adjustable valve and the latter takes a part of the flow of a pump proportional to the tilting angle of the machine.  The absorbed flow passes through the adjustable valve and then through the flow controller.  The other part of the flow of the pump passes through an electrically activated distributor to hydrostatic cylinders.  The hydrostatic cylinders convey to the body of the machine a movement of bringing back to the upright position.  The flow controller is made up of a rotary slide-valve, directly activated by the pendulum; the initial flow adjustment is achieved by means of a screw which adjusts the axial position of the rotary slide valve.  The varia-tion of the flow proportional to the tilting angle of the body of the machine is achieved by varying the superposition area of some openings in a frame and in the slide valve.

Abstract: ABSTRACT OF THE DISCLOSURE        A gas sampling analyzing system is provided whereby flue or process gasses are aspirated from a process duct to an analyzer and are therefrom returned back to the process duct to prevent condensation at the system exhaust. The sampling analyzing system is enclosed in an internally heated manifold to prevent condensation of the sampled gas and insure an accurate analysis by the system.  The sampling analyzing system has an analyzer assembly connected in parallel with a drop tube with the combina-tion being connected to a sample probe on one side and to a supply air operated aspirator on the other side.  The parallel drop tube allows a high flow rate to be main-tained between the sample probe and the aspirator to ensure a faster system response to changes in concentra-tions of the flue or process gasses.

The pipe is preheated and rotated about its longitudinal axis at constant speed, and is displaced relative to a powder spray coating device longitudinally of the pipe.  Powder material is discharged onto the pipe from the spray coating device, and excess powder material is withdrawn from the coating device.  For all pipe diameters, the speed of rotation of the pipe, the spacing of the coating device from the pipe and the amount of air sucked in per unit of time from the atmosphere are maintained constant, while the speed of the the relative displacement of the spray coating device and the pipe, longi-tudinally of the pipe, is varied in accordance with the pipe diameter.  The powder material is sprayed with an inert gas.  The coating device comprises a spray chamber in the form of a downwardly open housing adjustable in position relative to the pipe, and adapted to extend through, at most, 120° around the pipe, with the edge of the housing spaced from the pipe to define an air inlet gap.  A spray gun or the like is fixed relative to the housing for discharging the powder material within the housing.

The improvement comprises a free-wheeling drag wheel driven by the driven wheels, with a wiping means mounted on the driven wheels and actuated by the drag wheel to wipe the entire internal circumference of the cylindrical reactor.  The drag wheel generates a force to urge the wiping means outward against the internal circumference of the reactor.          The force is generated by the drag of the pool of polymer on the drag wheel.  This keeps the wall of the reactor wiped with a fresh film of polymer.  The process and apparatus is particularly adaptable to driven wheels and drag wheels eccentrically mounted in the reactor.

Abstract: ELECTRICALLY CONTROLLED SYSTEM FOR REGULATING THE        GRINDING SPACE IN A GRINDING APPARATUS                   ABSTRACT OF THE DISCLOSURE A system for measuring and regulating the grinding space be-tween two metallic grinding discs and to prevent direct contact therebetween; one of the discs being rotated while the other one remains stationary to grind therebetween fibrous cellulosic mater-ial, such as moisture-containing wood chips, for pulp making. One of the discs is electrically insulated from the other parts of the system and is included in an electric circuit with the positive and negative terminals connected to the disc at points electrically insulated from one another, and the moisture in the wood chips collected in the grinding space is used to produce a conductive cell, such as an electrolytic variable resistance, which bridges the two terminals and closes the circuit.  The resistance of the cell, which varies in response to fluctuations in the grinding space, is measured by an ammeter or similar measuring device which thus gives a reading of the width of the grinding space.  The measuring device may be used to actuate means for regulating the width of the grinding space and to stop the grinding operation im-mediately upon contact between the grinding discs.
