Abstract: Abstract In a boosted hydro-pneumatic drive for rapid traverse and power stroke, particularly for driving punching tools, a cylinder housing (1, 4) with partition (12), a disc piston (7) with plunger (8), a working piston (2) which can be loaded with compressed air for the return stroke and an annular piston (9) surrounding the plunger (8) are provided.    The cylinder spaces between the working piston (2) and the annular piston (9) on both sides of the partition (12) are filled with hydraulic oil.         In order to reduce the consumption of compressed air and to increase the speed of response, and for the purpose of simplification, the working piston (2) is provided with an annular surface (16a) which can be loaded with compressed air in the direction of advance, and a compression spring (10) is clamped between the disc piston (7) and the annular piston (9).     The space accommodating the compression spring (10) is in constant connection with the outside air, preferably via a filter (11).

Abstract: ABSTRACT OF THE DISCLOSURE     Hydrogen evolution in cells having zinc anodes is reduced or eliminated by incorporating in the cell a surfactant which is a complex phosphate ester of a surfactant of the ethy-lene oxide-adduct type.  This surfactant is added in such a manner that, directly or upon wetting of the anode by the elec-trolyte, there is an adsorption of surfactant on the surface of the zinc anode material, whereby hydrogen evolution is inhibited.          The surfactant is desirably present in the cell in an amount of from 0.001% to 5% by weight of the zinc component of the cell.

Title: Dual cycle heat pipe-method and apparatus

Abstract: DUAL CYCLE HEAT PIPE - METHOD AND APPARATUS               ABSTRACT OF THE DISCLOSURE     A method and apparatus for utilizing the earth or other heat source/heat sink for heating and cooling buildings are disclosed.  The system comprises at least one heat transfer fluid conduit and at least one heat pipe in heat transfer communication.  When two conduits are employed a dual cycle system for heating and cooling is disclosed.  In the preferred embodiment, upper and lower heat transfer fluid conduits containing a first heat transfer fluid are connected by heat pipes con-taining a second heat transfer fluid, the two fluids being isolated from one another.  The heat pipes are preferably sealed plastic tubes with hollow metal end caps at each end.  The metal end caps on the heat pipes are positioned in the circulation pipes so as to have sufficient contact with the recirculatory fluid in the respective heat transfer fluid conduits to trans-fer heat to and from such fluid.  In the summer, heated fluid flows through the lower conduit causing the second heat transfer fluid in the lower end cap of the heat pipe to boil and condense on the heat pipe wall giving off heat to the ground or other heat sink, thereby providing a cooling action on the first heat transfer fluid flowing through the lower conduit.  In winter, the lower conduit is shut down and the upper conduit acti-vated by passing cooled first heat transfer fluid through the upper conduit which condenses the second heat trans-fer fluid in the upper end cap causing it to flow by gravity down the walls of the heat pipe to a point at R-?156 which it boils and the resulting vapor then goes back up the heat pipe as a vapor, repeating the cycle and resulting in the heating of the first heat transfer fluid in the upper conduit.  Such a system can be used to both heat and cool buildings.
