Title: Two-piece wear-resistant spray nozzle construction
IPC: B05B1/00
Filed: 1978-02-23
Abstract: A spray nozzle having a brass housing and a urethane insert that is relatively resistant to wear by contact with the flow of irrigation water.

Patent ES-475541-A1 (ES)
Title: Incinerator
IPC: F23G5/16
Filed: 1978-11-29
Abstract: The invention relates to an incinerator for crematories, including a combustion chamber provided with charge inlet, flue gas outlet, supply means for combustion air, heat supply means and ash outlet. The novelty resides in the fact that the combustion chamber is placed in a unit which is movable, between two positions, relative to at least one stationary end wall in which the charge inlet and the flue gas outlet are provided, and is divided into at least two compartments which communicate with each other at some distance from the flue gas outlet and are adapted to be positioned, one at a time, at respectively the charge inlet and the flue gas outlet. The heat supply means works in the compartment present at the charge inlet at just that moment, and the combustion gases from said compartment will pass the other compartment on their way towards the flue gas outlet. The essential combustion of a charge introduced into the incinerator takes place in the compartment where the heat supply means is working, at the same time as the final burnout of a preceding charge takes place in the other compartment which has been displaced to a position adjacent the flue gas outlet and through which the combustion gases pass on their way to said outlet.

Title: Process for purifying liquids and/or regenerating absorbent solutions
IPC: B01D3/14
Filed: 1979-04-26
Abstract: The process for the purification of liquids and in particular the regeneration of spent absorbent solutions is essentially based on the use of a first preliminary regeneration zone to which the entire solution to be purified is delivered and the use of two terminal regeneration zones operating respectively at a higher and a lower pressure. The semi-regenerated solution issuing from the preliminary purification zone is split into two fractions which are delivered respectively to the low pressure and the high pressure terminal zones. The fraction delivered to the high pressure terminal zone is regenerated by steam yielded by means of the supply of external heat to the bottom of the zone. The fraction delivered to the low pressure terminal zone is regenerated by steam produced by heat recovered from the high pressure terminal zone.

Title: Drainable solar collector apparatus
IPC: F24S10/70
Filed: 1979-06-25
Abstract: The invention disclosed is a liquid constant flow, drainable solar energy collector system in which a manifold feeds several evacuated glass tube solar collectors disposed on an upward side of the manifold. The collectors are fed in parallel through an individual orifice which restricts flow rate to each solar tube. The normal outlet of each solar tube is via an axial glass pipe which extends to its top region. The orifices are all connected to a common header pipe in the manifold and the glass outlet pipes are all connected to a separate common header pipe in the manifold. For each solar tube the outlet pipe is of sufficient diameter in relation to the orifice so liquid that overflows the pipe does not completely fill it thereby always allowing an air vent passage via the same pipe. The restricted orifices are provided by inserts removably installed between their common header pipe and each of the solar tubes. The manifold is sloped to its drain and the collectors are sloped to the manifold providing full drainability and the collectors may use pure water without danger of freeze up or need for anti-freeze mixture.

Title: Electrodeposition of Aluminium Using Molten Electrolyte
IPC: C25C3/06
Filed: 1980-04-14
Abstract: An anode composition is used as the sole source of aluminum and comprises an aluminous material such as aluminum oxide and a reducing agent such as carbon. Electrodeposition is achieved at low temperatures and low electrical potential by the electrolysis in a fused salt containing the composite anode. The anode reacts to produce aluminum ions during the electrolysis, aluminum compound ionized at the anode is electrolytically reduced to molten aluminum at the cathode and an anion formed at the anode reacts to produce CO2 gas at the anode. In one operational mode a porous membrane passes electrolyte or other dissolved material while withholding undissolved impurities. Aluminum may be electrodeposited, at a temperature as low as the melting point of the metal and with the use of an all fluoride containing bath and the composite anode. Dimensionally stable cells for the electrodeposition have sloped walls forming electrodes that permit the maintenance of a reduced anode current density as well as anode- cathode spacing when using the low temperature non-aggressive baths permissible with the particular composite anode composition.
