Abstract

1,162,221. Electric blankets. DREAMLAND ELECTRICAL APPLIANCES Ltd. 16 Sept., 1966 [23 June, 1965], No. 26616/65. Heading H5H. An electrically heated pad or blanket has two heating elements 8, 10 defining two separate electrical circuits, each circuit being connected to a switch adapted to be connected to an electricity supply and having at least three operating positions so that the two circuits can be connected to the supply either singly or in series or in parallel. The length of one 10 of the heating elements 8, 10 is greater than the other, and the elements are disposed in substantially parallel U-shaped runs with a part of the runs of the longer element disposed in a region of the pad or blanket not containing the runs of the other element. The resistivities of the elements 8, 10 are such that when placed in parallel there is an even heat distribution over the pad or blanket, when placed in series there is an even heat distribution of less heat and when one circuit only is connected to the supply, one area of the pad or blanket is heated at a different temperature to the remaining area of the pad or blanket.
