Abstract: A device for washing clothes is formed as a large diameter tube closed at each end. It has a watertight disengageable closure between the ends, usually formed either as a cap or by unscrewing two parts of the tube and one or more intrusive portions of its wall extending into the inner space to promote turbulence when the tube is partly filled with clothes and water and then shaken. Larger sizes may be supported on two legs (or hung from a support) to facilitate shaking, and drain plates and water-removal ports can be provided.

Abstract: A bed or like equipment includes a loop of flexible material wide enough to hold a person lying down and a drive for material around the loop to rotate or rock the person. Preferably the loop hangs below and within the space between two parallel rollers with one or more rollers beneath the loop so that an endless belt of the material can be used.

Abstract: A container has an integral wall defining a moat or channel around its top edge and a lid that seals both with the rim of the container and the upper edge of the moat. The seal can be a plug-type seal, a telescope-type seal or a rim-seal where the rim of the container and/or the upper edge of the moat are held between integral upstanding walls on the rim. Combinations of two different types of seal may be used.

Abstract: A portable cooking installation consists of a heat-insulated enclosure containing a plurality of separately controllable electrical-resistance heating element surrounding and at least partially defining a space to receive a cooking vessel. For instance, two, three or four strip elements formed into circles of progressively increasing diameter (reckoning upwards) lie horizontally around a common axis to define a space to receive a suitably tapering cooking vessel; the elements can have aligned planar inner surfaces and be mounted on a resilient common support to improve vessel/element contact.
