Abstract: A timer control circuit is coupled with a battery charger to control on a timed basis the charging, shut-off and reset operations of the battery charger. The timer control circuit includes a timer, a d.c. power supply connected to the timer, and an auxiliary relay connected to the timer and connected between a battery and the battery charger. The timer is operable to repetitively and automatically turn on for a first preset timing period, turn off for a second preset timing period, and then turn on again for the first preset timing period. During each second preset timing period, when the timer is turned off, the auxiliary relay is normally deactuated so as to open a feedback path from the battery to the battery charger permitting the battery charger to reset in preparation for initiating a new charging cycle.

Abstract: A collapsible seat for attachment to a vertical support and adapted for use without modification as a game pull or arm sling. The seat includes a strap for encompassing a vertical support and a seat member of trapezoidal shape of a flexible material such as canvas. Webbing straps extend along the parallel bases of the trapezoidal seat and are joined at a distance from the seat sides to form a loop through which the strap passes for attachment to a vertical support.
