Abstract: Abstract of the Disclosure In a three phase welding power supply, the three phase power is connected to a welding arc by a power control circuit having three conducting paths for  straight polarity current and three conducting paths for  reverse  polarity  current.   The  power control  circuit  comprises  a  three  phase  bridge rectifier  circuit  having  eight  bridge  arms  each including  a  silicon controlled  rectifier  with  the bridge  circuit being  connected  between  the  three phase power source and the welding arc which is in turn  connected  to  the  three  phase  power  supply neutral.  An inductor is connected across the direct current terminals of the bridge circuit so that arc current flows in one direction through the inductor regardless of the polarity of the arc current.  The conducting paths are selectively activated at non-zero voltage points to conduct repetitive sequences of  independent  numbers  of  straight  polarity  half cycles of arc current followed by independent numbers of  reverse polarity half cycles of arc current  to the welding arc.  Pulses are generated in synchronism with each of the three power phases and counted to determine the activation sequences of the conducting paths.  By controlling the generation of the pulses and the counts of the pulses at which the paths are activated, a variety of sequences are generated.

Abstract: ABSTRACT OF THE DISCLOSURE   In a solid state color imaging apparatus for use in a compact color video camera, for example, in a horizontal direction, the color filter has two segments for each picture element of the solid state image sensor and the pattern of color segments is repeated with a period of two picture elements. The sums of the low frequency components of the output signals from the two picture elements are made equal for all lines of the picture elements.  In odd numbered lines, four color segments for the horizontal two picture elements may be magenta, cyan, green and yellow in regularly recurring sequence and in the even order lines, magenta, yellow, green and cyan in regularly recurring sequence.  Thus, high resolution, good uniformity of brightness and good S/N ratio are attainable.

Abstract: ABSTRACT         There is a requirement when using toilets to prevent and/or remove the accumulation of odour-causing substances from the sidewall of the toilet bowl.  This can easily be accomplished with ceramic toilets where the water is directed to swirl around by angled holes formed in the flushing rim.  However, in stainless steel toilets, the material is too thin to form angled holes and the water has previously simply entered a flushing rim and run vertically down the wall of the toilet.  This invention is an improvement in the flushing rim portion of a stainless steel toilet which causes the water to swirl around as in ceramic toilets, to effectively clean the inside of the toilet bowl.  Instead of drilled holes, the rim has upturned notches in its lower wall which cause the flushing water to spray the toilet bowl wall in an over-lapping pattern.  The notches also contribute to the swirling action of the water.

The dispenser has an elongated rectangular one-piece body of a flexible material that is dimensionally stable at ordinary temperatures.  A plurality of suppository cavities of uniform constant tapers with rounded bottoms are formed in tubular members extending from the top side of the body.  The body side surfaces are tapered with circular cross sections concentrically with the cavities.  These side surfaces merge together adjacent the topside and separate into the individual tubular members towards the bottoms of the cavities. The cavities have rounded bottoms to facilitate ejection of sup-positories by a manual pinching action.  A circular flat base formed on the rounded walls support the body upright on a work surface with the cavities upright to receive a suppository mixture.  A rectangular cover with open ends can be slideably mounted over the body in a telescope relationship.  In addi-tion, the body can have identical cavities or cavities varying in axial dimension so that identical and graduated doses can be provided in the suppositories from the same medicinal casting compound.

Abstract: ABSTRACT In the present invention a box-like tray having a capacity for holding a stack of more than 1,000 sheets of paper is positioned adjacent the paper-receiving slot of a photocopy machine.   A sheet-separator rides on top of the stack  of  paper  and  through  an  independent motor-drive mechanism feeds the top sheet to a feed-drive mechanism, which is also independently actuated.  The feed drive advances the sheet onto a teetering paper-receiving tray, the discharge end of which is positioned within the photocopy machine beneath the copier sheet-take-away roller.  A cam mechanism causes the discharge end of the tray to press the leading edge of the sheet against the take-away roller, and when the copier is actuated and the sheet is drawn its the copier, a sensing finger located on the tray detects the passage of the sheet and actuates the drive motors for the sheet separator and the feed rollers whereby to advance the next top sheet of the stack into position onto the tray, with the leading edge of the sheet positioned beneath  the copier  sheet-take-away roller.

Abstract: TWO-CHANNEL TACTICAL HERMAPHRODITIC FIBER CONNECTOR            Abstract of the Disclosure A connector for hermaphroditic coupling with a similar connector has a hermaphroditic end cap which mates with the end face of the connector body when the latter is not in use.  To ensure that the end cap is correctly located immediately the connector is disconnected, it is hinged to the connector body and spring-loaded to bias it closed.  When two connectors are connected together, their respective end caps mate automatically so that they too are kept clean.  This is possible because each end cap can pivot to a position in which its end face is coplanar with that of the connector body. Various locking devices are disclosed for locking two connectors together and for locking the end cap closed.
