Title: Wind turbine and method for power generation.
IPC: F03D11/02
Filed: 1981-03-02
Abstract: This invention is relating to a wind turbine for generation of electricity comprising a large, lightweight wheel attached to a fixed vertical central pylon and oriented to rotate in a vertical plane around a boom having an axis that is substantially horizontal, and pivoted at one end to the pylon. The wind wheel is supported at its rim by a carriage assembly that is constrained to move in a circular horizontal path about the central pylon. The wheel has a cylindrical outer rim and may include one or more perimeter frame structures. The outer surface of the rim is essentially flat in cross section and presents a traction surface for the takeoff of energy from the rim of the wheel. The wheel has a plurality of uniformly spaced radial spindles on which are rolled sails (soft airfoils), which when unfurled catch the wind to provide the rotational motion of the wheel. The carriage assembly may be moved around the pylon by driver means to accomodate for changes in wind direction, or the wind wheel as a whole can be allowed to move freely to assume the preferred wind direction in the manner of a weather vane. The wheel and frame structure are secured to and supports the horizontal boom which lies colinear with the axis of the wheel and projects longitudinally in both directions from the central plane of the wheel. The entire boom structure is supported by means of stays from the perimeter of the rim to the ends of the boom. Detailed rigging and traveler assemblies for control and operation of the wind turbine are disclosed.

Title: Transportable nitrogen evaporator and methods of evaporating nitrogen
IPC: E21B36/00
Filed: 1981-03-31
Abstract: A flameless nitrogen evaporating unit has a first internal combustion engine which drives a nitrogen pump via gearing. A second internal combustion engine drives three hydraulic oil pumps against a variable counterpressure so that the second engine can be loaded in a variable manner. By the nitrogen pump driven by the first engine, liquid nitrogen is pumped into a first heat exchanger, where heat from the exhaust gases of the first and second internal combustion engine is transferred to the liquid nitrogen in order to evaporate the nitrogen. The gaseous nitrogen then flows into a second heat exchanger, where, to heat the gaseous nitrogen essentially to ambient temperature, it is overheated by an engine coolant. The overheated nitrogen is then fed into the bore. The engine coolant circulates in a cooling system. Heat is transferred directly to the coolant from the internal combustion engine. In addition, heat is transferred to the coolant from the lubricating oil delivered by the three pumps attached to the second internal combustion engine. The coolant circulating system contains a mixing chamber in which the warmer coolant flowing from the internal combustion engines to the second heat exchanger and the cooler coolant flowing from the second heat exchanger to the internal combustion engines are mixed. Methods of evaporating nitrogen are likewise disclosed.

Patent ES-8301349-A1 (ES)
Title: Electrically heated apparatus for domestic use.
IPC: H05B3/48
Filed: 1981-07-10
Abstract: The apparatus has a vat (12), in which water is used for cleaning purposes, for example for washing dishes. The water passes into the apparatus through a throughflow heater (17), arranged outside the vat (12), from where it passes via a pipe (18) into the vat (12). In order to keep any damage as low as possible even if all safety devices fail, the throughflow heater has a high output in relation to its surface so that its heating device burns through if the throughflow heater (17) operates without water, in which case the excessive temperature thereby occurring is limited to the throughflow heater (17) itself. The characteristics of the throughflow heater (17) are selected such that burning-through of the heating device actually occurs if it operates without water. In preferred embodiments, it is ensured by corresponding design of the throughflow heater that a good eddying of the water occurs in the latter without the formation of bubbles.
