Abstract: ABSTRACT OF THE DISCLOSURE A heat pump for use in heating or cooling residential, commer-cial or industrial buildings, industrial and agricultural processes and heating of water to moderate temperatures such as may be required in swimming pools or as a water pre-heater for any other use. The system includes a fuel consuming refrigerant boiler for producing a refrigerant in vaporized form at relatively high pressure, the output of the boiler being connected to a superheater and then to the primary jet of an ejector-type compressor. An evaporator unit exposed to ambient temperatures has its output line con-nected to an inlet of the ejector such that as the high pressure gaseous refrigerant flows through the nozzle of the ejector, a low pressure is created and the refrigerant from the evaporator is also caused to flow through the ejector compressor to a condenser where the refrigerant is allowed to give up its heat. The condenser is coupled in circuit with a receiver which holds liquid refrigerant and delivers same to the boiler and evaporator, all under control of fluid level or pressure sensitive switches governing the operation of a liquid refrigerant pumping means.

Abstract: BACKER FOR ELECTRON BEAM HOLE DRILLING                   ABSTRACT OF THE DISCLOSURE Disclosed is an electron beam hole drilling process in which the workpiece surface where the hole exits is covered with a backer comprising particulate bonded to itself and the exit surface by a binding agent.  The backer enables a hole having substantial uniform symmetry along its length to be drilled and is particularly useful for hollow parts and contoured surfaces.  Backers removable by liquifying, melting, dissolution, leaching and the like, are particularly useful for inaccessible exit surfaces.  In a preferred embodiment the backer is comprised of a nonmetallic particulate such as glass while the binder is a soluble silicate.

Water (8,8') is introduced into the (to be) heated combustion air flow (30,33) cooling it by its evaporation, and the vapor is partially condensed again in a cooler (6) fitted in the compressed flow (34) after leaving the compressor (4). The condensation can take place at higher temperature, thus the system acts as heat pump for the waste heat. The compressed air flow (35) enters extra cooled into the combustion chamber (2) which provides an additional advantage.  For the compressor (4), combustion chamber (2) and turbine (3) a normal gas turbine may be used.

Abstract: ABSTRACT OF INVENTION      A method and system for processing induction measurements of sub-surface formations taken by an induction logging system at various depths in a borehole is disclosed.  The method reduces the unwanted contributions in each measure-ment from induction currents flowing in the formations spaced apart from each measurement depth.  The spatial domain sonde response function obtained at zero conduc-tivity is Fourier transformed and truncated at a spatial frequency less than the spatial frequency at which the transformed function first goes to zero.  A Kaiser window transfer function is then selected and the inverse Fourier transform of the ratio of the Kaiser window function to the transformed truncated sonde response function is formed to obtain a deconvolution filter function which when convolved with the sonde response function reduces the non-zero sidelobes in the system response function and thus reduces the shoulder effect.
