Abstract: Abstract of the Disclosure A single mode optical waveguide is constructed in a manner such that the core thereof is subjected to a stress-induced birefringence.  In accordance with one embodiment the fiber comprises an oblong core surrounded by an oblong inner cladding layer.  An outer layer of stress cladding glass, which has a circular outer surface, surrounds the inner cladding layer.  The TCE of the stress cladding glass is different from that of the inner cladding glass.  In another embodiment the stress-induced birefringence is accomplished by introducing into the cladding region of the fiber on opposite sides of the core longitudinally extending regions of glass having a thermal coefficient of expansion different from that of the remainder of the cladding.  A number of novel techniques are disclosed for forming such fibers.

Abstract: SPEED REDUCING CONTROL SYSTEM FOR A POLYPHASE ELECTRIC MOTOR                  ABSTRACT OF THE DISCLOSURE     A variable speed 3-phase a-c motor is connected to a 3-phase source of alternating voltage via five controllable bidirectional solid state switches which are so arranged and controlled that motor speed can be reduced by skipping selected cycles of the source voltage. For example, for half speed operation three of the switches are arranged respectively to connect phases A, B and C of the source to phases A, C and B of the motor, and over two consecutive periods of the source voltage three separate, uniformly spaced "firing windows" are selected during which the conducting states of these switches are initiated in a predetermined pattern that results in the phase A-to-phase B source voltage being applied to the motor during the first window, the phase C-to-phase A source voltage being applied during the next window, and the phase B-to-phase C source voltage being applied during the last window.

Abstract: ABSTRACT OF THE DISCLOSURE            Modifications in a levelling device for ladders and the like are provided.  Apertured lug, adapted for attachment to the bottom ends of uprights, stiles or legs of a ladder, trestle, etc., are slidably mounted on an arcuate support bar, and biased to a non-locking or freely slidable position.  On application of weight to the ladder, the apertured lugs pivot to a locking position.  In one embodiment, each of the apertured lugs is formed with extension members or fingers with abutment surfaces extending parallel to the plane of the ladder which tangentially engage the sides of the support bar when the apertured lugs are in locked position to prevent or limit any tiltable movement of the support bar out of the plane of the ladder.  In another aspect of the invention, the lugs are provided with non-circular apertures and the support bar is formed with a complementary non-circular cross-sectional configuration, such as triangular, square, etc., which configurations prevent rotation of each apertured lug around the support bar, and thus prevent or limit tilting of the support bar out of the plane of the ladder.  The levelling device of the present invention may be used on any number of different sizes of ladder to provide stable and safe levelling of the ladder.

Abstract: ABSTRACT OF THE DISCLOSURE:           Comminuted  salvaged rubber  is  heated  to  the reclaiming  temperature  in  a  two-stage  process such  that part of the overall heat required is introduced by way of microwave heating and the remainder by way of convectional heating, e.g. by way of a heating screw. The material prehea-ted during the first stage is tranferred to the second stage in such a way that the position of all the particles rela-tive  to one another is maintained with as little change as possible.  Since the temperature profile characteristic of microwave heating shows a maximum in the interior and a minimum at the periphery,  whereas  that of convectional heating is just the reverse,  the temperature distribution within the material can be evened out to a great extent by combining these two different methods of heating. Since it is no longer necessary in this case to heat the material to such an extent convectionally, it is possible to avoid caking and the formation of deposits, and thus to considera-bly improve the quality of the reclaimed rubber.  Instead of the self-cleaning double-screw apparatus with intermesh-ing helices it is possible to use single-screw heat exchan-gers  (single-helix  hollow-flight  screw  heat  exchangers). Single-screw apparatuses have the advantage, among others, that screw blades of rectangular cross-section can be em-ployed,  that guarantee a more uniform heat supply to all parts of the material being treated than curved ones do.

Abstract: ABSTRACT OF THE DISCLOSURE          A diaphragm pump pumping arrangement includes two diaphragm pumps which are arranged and operate in tandem.  Each of the diaphragm pumps includes a housing and a movable wall that includes a flexible diaphragm and subdivides the interior of the respective pump housing into a pumping chamber and an actuating chamber.  An air distributing control arrangement interposed between and connected to the pump housings includes a spool valve movable in a bore of an aluminum casing of the control arrangement between two end positions in which it alternatingly achieves the admission of the compressed air into one, and discharge of the air from the other, actuating chamber.  The spool valve is displaced due to the action of respective limiting valves accommodated in individual bores of the control arrangement and displaced by the respective movable walls from their rest positions in which they admit the ambient pressure to the associated end faces to their active positions in which they admit the compressed air to the associated end faces of the spool valve.  The spool valve carries sealing rings of a material that needs no lubrication, and is made, at least at its peripheral surface, of a material that also needs no lubrication, and the surface bonding the bore for the spool valve is hard-anodized, so that no external lubrication of the control arrangement, by lubricant entrained in the compressed air or otherwise, is needed.
