Abstract: A flat, normally horizontal electric resistance blanket heater comprising a thin, fragile elongate resistance element on one surface of and carried by a thin, flexible sheet of dielectric material, a thin, flat resilient and flexible reinforcing strate of dimensionally stable material retained adjacent the other surface of the film to permit flexure of the heater and without dimensional distortion of the film and element and a flexible envelope encapsulating the sheet element and strate.The heater also includes temperature responsive switching means responsive to the temperature of heated portions of the heater and in temperature insulated relationship from a portion of the heater where the element connects with power supply lines and which creates a portion in the heater of increased mass and heat storing capacity.

Abstract: A water bed crib comprising a water bed structure including a flat horizontal rectangular platform with an upwardly projecting weir about its perimeter, a water filled flexible mattress bladder supported atop the platform within the confines of the weir, platform legs at and depending from the four corner portions of the platform, floor engaging caster wheels at the lower end portions of the platform legs, crib frame leg supporting brackets projecting outwardly from the platform legs; a rectangular crib frame with vertical end boards and vertical side gates engaged about the water bed structure and having crib frame legs depending from its four corners and engaging the brackets on the platform legs; the crib frame legs have caster pintle receiving openings in their lower ends and the brackets have retaining pintles engaged in said openings.

Abstract: The combination of a water filled flotation bed mattress with a filler neck and an elongate flexible cord-like heater structure comprising an elongate power supply cord section with inside and outside end portions and a filler neck engaging and sealing means between its end portions and engaged in and sealing said neck with said inside end portion extending into the mattress and the outside portion extends from the mattress, an elongate flexible resistance heater section with inner and outer ends arranged within the mattresses and including a water proof jacket structure and an elongate resistance element within extending from the inner to the outer end and thence to the inner end of jacket structures; and temperature control means including an elongate rigid metal tube with inner and outer ends engaged with and between the free end of said inside portion of the cord section and the inner end of the heater section, insulated conductors extending through the tube and connecting ends of the element with related
