Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to an improved process for the production of practically non-hygroscopic, easily grind-able copper (II) sulfate monohydrate which is stable even in finely ground state and can be applied as trace element additive in animal fodders, by neutralizing the free sulfurio acid content of copper (II) sulfate pentahydrate with sodium, potassium or ammonium hydroxide, carbonate or hydrocarbonate (further on? alkaline agent) and removing four moles of its crystal water content by drying at 80 to 150°C for at least 30 minutes.  The improvement according to the invention consists in that copper (II) sulfate pentahydrate, melted in its own crystal water, is treated with 3 to 20 % by weight, preferably 5 to 8 % by weight, of an alkaline agent calculat-ed as sodium carbonate for the weight of the copper (II) sulfate pentahydrate, over the stoichiometric amount required to neutralize the free sulfuric acid content.           By the method of the invention stabilized copper (II) sulfate monohydrate can be prepared on industrial scale directly from copper (II) sulfate pentahydrate, a cheap start-ing substance. The process can be performed very easily and economically.

Abstract: D 39E3 ?) INVENTION: A DEVICE FOR WINDING AND REELING AN ELONGATED, FLEXIBLE MEMBER ABSTRACT OF THE DISCLOSURE A winding and reeling device for an elongated, flexible member. A reel is connected to the outer end of a spiral spring. The outer end of the spiral spring is rigidly connected to the reel, and a gear train acts between the outer and the inner end of the spiral spring such that upon rotation of the outer end of the spiral spring around its center axis the inner end of the spiral spring rotates around the same axis, however at a slower rotational speed. The reel has smooth surfaces and comprises at no place and gear teeth. A rotation of the reel causes the rotation of the gear wheels of the gear train, whereby two gear wheels having a different number of teeth are rigidly connected to each other and arranged on a common shaft. A further shaft is provided which carries two further gear wheels, whereby one gear wheel is rigidly connected to the further shaft and the other gear wheel is freely rotatable of said further shaft. The gear train provides a speed reduction, whereby its input end is driven by the reel and its output end drives the inner end of the spiral spring. Accordingly, the space occupied by the spiral spring is smaller than hitherto possible, and a space saving of the entire device is achieved. The device is suitable for reeling weblike members such as measuring tapes or leashes for dogs and also for reeling electrical cables such as for instance used in vacuum cleaners.

Abstract: ABSTRACT OF THE DISCLOSURE      Method and apparatus for generating power which includes a closed loop path through which a working fluid is circulated is disclosed.  The circulation path includes a prime mover, such as a turbine, to which operating fluid in the vapor state is supplied from an evaporation chamber which is partically filled with oper-ating liquid.  A condenser is located within the operating li-quid within the evaporation chamber adjacent the bottom of the chamber, through which condenser working vapor discharged from the turbine is passed for cooling the vapor to condense the same, with the heat of vaporzation passing from the vapor into the opera-ting liquid within the evaporation chamber.  Operating liquid from the condenser is pumped through heating means, such as a solar collector, for heating the liquid without vaporizing the same.    The heated working liquid from the heating means is passed into the evaporation chamber for vaporization thereof. Heat in operating liquid within the evaporation chamber is ab-sorbed as heat of vaporization by the evaporating operating liquid to cool operating liquid in the evaporation chamber.  The cold operating liquid at the bottom of the chamber facilitates removal of heat from the turbine exhaust through the condenser at the bottom of the chamber.  The turbine may be used to drive a genertor which, in turn, may supply electrical energy to an electrical motor.  The system is well adapted for use with a vehicle, wherein a solor collector is mounted on the vehicle roof for use in heating the working fluid.

Abstract: VISCOUS OIL RECOVERY METHOD         (D#76,771-F) ABSTRACT OF THE DISCLOSURE         Disclosed is an improved viscous oil recovery method employing the injection of a thermal recovery fluid which may be steam or a mixture of steam and additives, and cycles of pressurization and drawdown.  First the thermal recovery fluid is injected and production is restricted in order to increase the pressure in the reservoir.  Injection is then terminated or decreased and production is increased in order to effect a pressure drawdown in the reservoir.          Thereafter the production rate is decreased or production wells are shut in completely and non-condensable gas is injected to raise the pressure in the reservoir to a value which is from 50 to 90 percent of the final target pressure, after which the thermal recovery fluid is again injected into the formation to rebuild reservoir pressure with re-stricted production.  Finally, production rate is increased and thermal recovery fluid injection is reduced or ter-minated in order to accomplish another reservoir drawdown cycle.  Additional cycles of partial repressuring with non condensable gas followed by steam injection followed by pressure drawdown production cycles may be employed.     -I-
