Abstract: A ligature carrier for use in a suspensory-type operation known as the Revised Pereyra Procedure, which corrects prolapse of the bladder neck in women. The ligature carrier comprises an angulated needle with two aligned striated flat handles, one slidable in a brace with respect to the other to extend and retract the needle. When retracted the angulated end of the needle protrudes about 3 cm; the aligned handles provide improved control to penetrate the abdominal fascia and orient the needle thereafter. In the operation the tough fascia is so penetrated, the carrier suitably redirected, and the needle extended out through the vaginal opening by sliding the needle handle in the brace. Sutures are then threaded through the eye at the needle tip and the needle retracted.

Abstract: A small well fills with rain water and a float in the well rises to interrupt a light beam that falls on a photoelectric cell. The photoelectric cell keeps a control circuit open as long as it is exposed to the light beam and closes the control circuit in the absence of a light beam. The photoelectric cell turns on a blower to inflate a swimming pool cover and simultaneously energizes a lamp bulb to evaporate the water in the small well. When the rain ceases the lamp bulb evaporates the water in the well to lower the float and thereby stop the blower and turn off the lamp bulb. A selector switch has a normal first position to ready the rain-responsive control circuit and has a second position for energizing the blower directly when a person desires to inflate the swimming pool cover for use of the swimming pool in the absence of rain.
