TL;DR: In this article, an approach for heating thermoplastic parisons to a substantially uniform temperature across their wall thickness prior to a blow molding operation is described. But the parisons are rotated about their longitudinal axes while being conveyed adjacent a thermal conditioning means, which includes vertically spaced radiant heating elements and a gaseous cooling source.
Abstract: Apparatus is disclosed for heating thermoplastic parisons to a substantially uniform temperature across their wall thickness prior to a blow molding operation. The parisons are rotated about their longitudinal axes while being conveyed adjacent a thermal conditioning means, which includes vertically spaced radiant heating elements and a gaseous cooling source. The heating elements radiate infra-red rays having a wave length to penetrate and heat the full thickness of the parison wall; whereas the gaseous cooling source directs a stream of air onto the surface of the parison facing the heating elements to prevent the parison surface from being overheated. Additionally, each of the heating elements may be individually regulated so that the parisons can be differentially heated along their axes to control the wall thickness of the final blown articles.

Abstract: A heating system employing a heat pump, which is provided with a source of heat created by a second system employing refrigerant as a heat transfer medium, is provided. In the second system the refrigerant passes through a structure wherein the refrigerant is boiled. The refrigerant is then passed by vapor pressure to a heat exchange structure where it gives off heat. The heat energy for boiling such refrigerant may be a readily available source of heat such as the ground, or a water storage system such as a pond, lake, swimming pool, river, well, or creek.

TL;DR: In this paper, a home heating and cooling system consisting of a pair of large water tanks and a heat-operated absorption-type refrigeration system disposed between the tanks and operable to transfer heat from one tank to the other is described.
Abstract: A home heating and cooling system consisting of a pair of large water tanks and a heat-operated absorption-type refrigeration system disposed between the tanks and operable to transfer heat from one tank to the other. The "hot" tank supplies hot water for operating a hot water home heating system, supplies a portion of the heat necessary to operate the refrigeration system, and may also operate a home hot water supply system, drawing heat from the "cold" tank and from the atmosphere through the refrigeration system. In periods of low heat demand, it may store large amounts of heat for later use in periods of higher demand, thereby reducing the heating load imposed on the refrigeration unit. The "cold" tank supplies a cold liquid for a home cooling system operable by such liquid, and the heat absorbed by said cooling system, together with heat absorbed from the atmosphere, is transferred to the hot tank by the refrigeration unit. The cold tank is capable of storing large quantities of cold water, or even ice, in periods of zero or low cooling demand, which may absorb the heat removed by the cooling system, whereby to reduce the cooling load on the refrigeration system in periods of higher demand for cooling.

TL;DR: In this paper, the authors describe a heat pump with an electrically driven compresser and an expansion valve, which is formed by a coil of refrigerant within a chamber through which air is drawn from the atmosphere through ducts buried in the soil.
Abstract: A heat pump has an electrically driven compresser (3) and an expansion valve (5). The evaporator (2) is formed by a coil of refrigerant within a chamber (16) through which air (6) is blown by a fan. This air is drawn from the atmosphere through ducts buried in the soil.

This ensures a good coefficient of performance which is not reduced by low outside air temperatures. The heat is given up in the condenser (4) to water circulating in a space heating system (13). To obtain max. efficiency the heating can be a floor heating (8) operating at a moderate temp.

TL;DR: In this article, a space heating system having a low inertia (low mass and low water content) boiler and a larger heated water storage tank providing a bank of hot water (hereafter called the heat bank) and a "flywheel" effect is described.
Abstract: A space heating system having a low inertia (low mass and low water content) boiler and a larger heated water storage tank providing a bank of hot water (hereafter called the heat bank) and a "fly-wheel" effect. This provides a thermal bank or load leveler. The temperature of the water in the tank controls "on-off" operation of the furnace of the boiler. The heat sensing means for the heated space controls only the operation of the circulator in the system. A plurality of zones with a common return may be used. The flow rate from the boiler into each of the zones is controlled to be less than the rate of flow from the boiler to the heat bank so that its stored supply of heated water may be quickly established. A domestic water heating coil may be mounted in the heat bank. The connection from the boiler to the heat bank is preferably to the top of the tank which forms the heat bank. The connections to the domestic water heating coil are also preferably at the top of the heat bank. The means for sensing the temperature of the water in the heat bank is preferably associated with the bottom area of the heat bank. In addition, the system lends itself for use with a solar heat source for supplementary heat input.
