Abstract: ABSTRACT           Molded optical waveguide switching apparatus wherein a flat, planar light transmissive plastic member of a refractive index N2 is premolded with orthognally arranged obverse and reverse grooves or channels and wherein each such channel or groove is filled-in or molded with a light transmissive plastic of a refractive index N1 (where N1> N2) effectively forming front and back light conducting channels or waveguides at right angles to one another on the flat planar member.  A gently curved tap is molded into the intersecting area of each row and column waveguide with a through opening or aperture formed adjacent each intersection.  The taps of the obverse side are curved downwardly to meet the upwardly curved taps of the reverse side of the planar member. Light blocking and unblocking members are operably disposed in respective apertures to interrupt light from light generating to light receiving receptors.

Abstract: Abstract A vacuum floor polisher uses the polishing material fed by gravity from a tank and dropped onto the floor through the center of a polishing disc which rotates the polishing material on the floor.   The floor is polished by the rotating polishing disc and with the polishing material fed, which after polishing is sucked up by the stream of air and recovered into the upper tank.  By applying adequate cleaner into the polishing material, the dirts of the floor is polished and removed by the rotating disc and the polishing material.  The dirts are sticked to the polishing material.  By mixing wax to the polishing material, the waxing is also done together with the polishing step.

Abstract: ABSTRACT OF THE DISCLOSURE     A variable speed drive for an AC motor has features to improve the power factor.  The system uses a rectifier for converting AC supply voltage into DC voltage on a positive rail and a negative rail.  Frequency switches are controlled to alternately connect the rails to the power conductors at a variable rate to define a selected voltage frequency.  An amplitude  switch  is  located  on  one  of  the  rails  and controlled  to  vary  the  potential  between  the  rails  in proportion to the frequency.  A current sensor senses the current waveform in one of the conductors and applies it to a  phase  detector  which  detects  the  difference  in  phase between  the  current  and  the  voltage.   Phase  difference pulses are produced which are averaged into an average DC value.  The DC value is applied to a demand voltage that controls the amplitude switch to reduce the amplitude to improve power factor.

Abstract: ABSTRACT OF THE DISCLOSURE           The DC power supply current-collected on the electric car is connected with a series circuit of the armature of a driving DC motor and an armature current control chopper and with a series circuit of a field winding and a field current control chopper.         Both choppers are controlled so that the arma-ture current and field current are maintained constant until the flow rate of the armature chopper reaches the maximum after starting of electric car.  In this period of time, the chopping frequency of the armature chopper is higher than that of the field chopper.         When the flow rate of the armature chopper reaches the maximum, the chopping frequency of the armature chopper is made coincident with that of the field chopper.  At the same time, the field chopper is switched to the control operation by which the field current is decreased in order that the decrease of the armature current is restricted.         When the speed of the electric car is further increased so that the field current tends to decrease below the weak field limit value, a control system is operated to suppress the tendency and thereafter the field current becomes constant.         The chopping frequencies of both choppers are determined on the basis of a common clock pulse.

Abstract: ABSTRACT A process for forming a copolymer of styrene and butadiene in which an aqueous mixture comprising water, styrene monomer, butadiene monomer, a suspension stabilizing agent, and a chain-propagating amount of a free radical polymerization initiator insoluble in water, soluble in the styrene monomer and soluble in the butadiene monomer is heated in an inert atmosphere to a temperature between about 50°C and about 130°C in the absence of redox initiators and mercaptan compounds until the monomers form an aqueous suspension of discrete copolymer particles having a Tg value of between about 45°C and 65°C and a weight average molecular weight of between about 10,000 and about 250.000. Increased molecular weight distribution of the final copolymer may be achieved by introducing additional styrene monomer, butadiene monomer, suspension stabilizing agent and initiator to the aqueous mixture at least once during the heating step. Optimum yields are achieved by heating the aqueous mixture with at least two different initiators in accordance with a predetermined multistage healing profile.
