Abstract: A heating apparatus having a refrigeration cycle includes a compressor, a condenser and an evaporator. The heating apparatus has a first heat exchanger and a second heat exchanger, where the first heat exchanger is selected as a heat source, and the second heat exchanger is selected as either a cooling or heating source. The first heat exchanger and the second heat exchanger are connected in series with each other in a refrigerant circuit. A heating medium is circulated in a heat transfer device which is connected to the first heat exchanger. Bathwater of a bathtub and water of a hot-water storage tank are heated through the heat transfer device indirectly by the first heat exchanger.

Abstract: An apparatus for accurately infusing medicinal agents into an ambulatory patient at specific rates over extended periods of time. The apparatus is of a compact, low profile, laminate construction and includes either an elastic distendable membrane, or a thin barrier member which, in cooperation with a thin planar base defines a fluid chamber having a fluid outlet. The apparatus includes an internal stored energy source which functions to controllably expel the medicinal agents from the apparatus. The stored energy source may comprise either a distendable elastomeric membrane of an expandable sponge like cellular mass.

Abstract: An apparatus for accurately infusing medicinal agents into an ambulatory patient at specific rates over extended periods of time. The apparatus is of a compact, low profile, laminate construction and includes an elastic distendable membrane, which, in cooperation with a thin planar base, defines a fluid chamber having a fluid outlet. Disposed within the fluid chamber is a thin fluid permeable member which precisely controls the rate of fluid flow through the fluid outlet.
