Title: Chromising of ferrous substrates in molten lead bath - using low chromium content to reduce roughness and porosity of coating
Inventor: RAUSCH JOHN J
IPC: C23C10/22
Filed: 1979-07-06
Abstract: A ferrous-based substrate is chromised by diffusion coating from a molten alloy bath consisting mainly of lead and contg. 0.85% chromium based on the weight of Pb, Pb being the only transfer agent in the bath and Cr pref. being the only diffusing element. Reduction of the Cr content of the bath results in reduced Cr concn. in the coating, giving improved ductility and malleability while still imparting adequate corrosion resistance and reducing costs. In addition, the risk of producing a rough, porous coating, which can occur during cooling of the bath due to Cr precipitating out of soluion, is reduced.

Title: Supplying underground heat to external heat pump - from sealed vertical concentric tube exchanger using circulating medium
Inventor: WUERZBURGER HANS
IPC: E21B17/18
Filed: 1980-04-19
Abstract: In the extn. of heat from the earth and/or from underground water supplies to be delivered to a heat pump for use in heating buildings etc., a heat exchanger circulates an intermediate liq. carrier medium in a closed circuit which includes a low conductivity inner tube surrounded by a higher conductivity tube with a closed end and preferably of corrugated shape. The exchanger absorbs heat from the underground source when inserted into a bore-hole, and transmits heat to the above-ground primary side of the heat pump for delivery to the user structure. The heat exchange medium may be a mixt. of water and ethylene glycol when the heat pump works intermittently, the "off" periods allow further time for heat migration to the cooled area. Water supplies are not endangered, since water is not extracted at any stage, merely its heat, which is restored from the adjacent ground.
