Abstract: Abstract of the Disclosure Integrated optics directional coupler modulator/switches are improved by the disclosed configurations for switching optical modes of both polarizations at once.  In one configuration a pair of parallel optical waveguides are provided having material presenting first and second wavenumbers B for the TE and TM modes.  Two independently tunable control signals are applied to an electrode assembly arranged so that each wavenumber is substantially tunable relative to the other thereby permitting substantially complete switching of both of the modes.  In an exemplary embodiment, the material is lithium niobate or lithium tantalate with its c-axis perpendicular to the waveguides and oriented between 15 and 75 degrees, suitably at 45 degree, to the substrate plane. Pairs and triplets of electrodes are used as appropriate to provide vertical and horizontal electric field components so as to independently tune the waveguide wavenumbers and coupling.  The principles are applicable to electromagnetic apparatus in general and a variety of physical fields are alternatively used as appropriate for achieving the dual polarization control.

Abstract: ABSTRACT OF THE DISCLOSURE           A collapsible bathing assembly utilizes a flexible liner housed within a cabinet.  Rigid side walls for supporting the side walls of the liner are pivotally joined to the cabinet, and by pivoting action move the liner into and out of the cabinet.  The rigid side walls and a rigid bottom support plate serve as the side walls and front wall of the cabinet when the liner is positioned within the cabinet and the bathing assembly is not in use.  A rigid end wall is mounted for pivotal movement about an axis adjacent to the bottom of the liner to provide for the adjustable supporting of one of the ends of the liner, particularly to provide for collapsing of that liner end onto the bottom of the liner, resulting in easy access to the bathtub for an invalid.  A framework is provided to support the top of the cabinet and to facilitate installation of the bathing assembly, including plumbing.  The liner may be omitted, if desired, in which case the walls are provided with water-tight seals.

Abstract: Abstract of the Disclosure:          A manually operable locking mechanism for an auto-matic transmission has a pawl which engages a toothed member connected to the transmission output shaft.  The pawl is con-trolled for engagement and disengagement with the toothed member through a manually operated cam which moves a lock lever toward the engaged position.  The lock lever, through a tension spring, urges a lock strut to enforce engagement of the pawl.  On manual disengagement, the cam contacts and moves the lock strut to relieve the locking force from the pawl thus permitting dis-engagement of the pawl and the toothed member.  The lock lever abuts the cam after disengagement to establish the relative positions of the cam, lock lever and lock strut when the dis-engage position is selected.

Abstract: ABSTRACT            REMOVING FLUID AND DEBRIS FROM PIPELINES      To remove fluid and/for particulate debris from a pipeline, a Bingham plastic fluid plug is passed through a pipeline and the fluid and/or debris (4) are collected by the plug. The plug (3) is pushed through the pipeline (1) with a scraper (2) which in turn may be pushed by liquid or gas pressure. Where the fluid to be removed is water, the Bingham plastic fluid plug employed pre-ferably is a composition of water and a xanthan gum, and the gum may be cross-linked with a multivalent metal. Where the fluid to be removed is a hydrocarbon, the Bingham plastic fluid plug employed preferably is a composition of a mineral oil and an organo-modified smectite, and may also include a particulate filler such as powdered coal (Figure 1).

Abstract: FLUID FILLED BEDS AND THE LIKE     ABSTRACT OF THE INVENTION     Apparatus and method are disclosed which pertain to inflatable structures useful as air beds and the like.  Shape and load con-trol are facilitated by a plurality of bladders that are located within an inflatable chamber of the structure and are joined to opposed imperforate walls thereof.  The bladders are provided with vents which lend to the interior of the chamber, and upon inflation of the structure and resultant separation of the opposed walls of the chamber, the bladders are caused to extend from a flattened state, become filled with the fluid used for inflating the structure, and assume a roughly cylindrical con-voluted configuration.  Being made of a flexible, substantially non-extensible material, such as vinyl plastics, there is a limit to which the bladders can extend, and further vertical separation or lateral shifting of the attached opposed walls is thereby restrained.  When the bladders are provided with vents, they "breathe" when a physical load is applied to the inflated struc-ture or removed from it, hence, regulating resiliency by means of an "air spring" effect.

Abstract: ABSTRACT           A ballast for starting and operating series-sequence fluorescent lamps includes a capacitor in the operating circuit which comes into play when the second of two lamps is ignited and permits the establishment of series capacitive reactance in the operating circuit which controls the level of lighting.          The capacitor may be connected in such a manner that the lighting level is permanently established by suitable connection when the ballast is connected into the lighting circuit or it may be selectively connected, alone or alternatively with another capacitor or a direct connection through the medium of an external switch to provide selective levels chosen by the user, The ballast is of the type which starts the lamps with the use of a lagging circuit but switches the circuit into leading when the second lamp has ignited and is leading thereafter.

A chain saw with a substantially horizontal effective cutting edge at least as long as the log is supported at only one end by a saw mounting assembly with the cutting edge generally parallel to the axis of the log.  The saw mounting assembly is adapted for lateral movement relative to the log, as well as upward and downward movement, so that the saw can be posi-tioned beneath a portion of the log and moved upwardly through the log to cut wood slabs.  The saw is pivoted to the saw mounting assembly so that the angle between the effective cutting edge and the axis of the log can be adjusted to produce elongated wood fibers during cutting.          A pivoting mechanism is provided for rotating the log between cuts so that slabs tapered from one side to the other can be cut.  The saw mounting assembly is also adapted for pivoting about a vertical axis to move the cutting edge out of a vertical plane parallel to the previous cut so that longitudinally tapered slabs can be sawn.

Abstract: ABSTRACT OF THE DISCLOSURE         There is provided an arm rest assembly for a chair or the like, including an arm rest member and a support member which are pivoted together.  The arm rest member has a top surface and the support member terminates below the top surface and is pivoted thereto at a location slightly rearwardly of the forward end.  These members define an angle which changes as the chair is adjusted, and the arm rest member includes stop means forwardly of the support member and below the top surface, the stop means being adapted to come into contact with the support member when the angle enlarges to a predetermined size less than 180°.  This prevents the arm rest and support members from reaching a "dead centre" position, and avoids risk that the user's fingers will be come trapped between the support member and the forward end of the arm rest member.
