Patent EP-0240111-A2 (EP)
Inventor: STEVENSON GERALD ROBERT
IPC: B01D59/28
Filed: 1987-02-04
Abstract: A method of isotope enrichment including providing a reactant. The reactant is a mixture of at least two isotopic compounds. One of the isotopic compounds has a greater percentage of a selected isotope than the other. An electron transfer agent is introduced into the reactant isotope mixture to form a reaction mixture. The electron transfer agent facilitates transfer of electrons interactive with one or more selected nuclei of the reactant. The electron transfer agent is in an amount sufficient upon reaction of the reaction mixture to establish an equilibrium between an electron rich reaction product and an electron poor reaction product. The reaction mixture is reacted until the equilibrium is established. The electron poor reaction product is then separated from the electron rich reaction product.

Abstract: This invention describes a method for automatically pro­viding correctly spelled compound words as candidates to replace a misspelled compound word in many natural lang­uages such as Dutch, Danish, German, Icelandic, Norwegian, Swedish, Swiss German, etc. The basic technique consists of looking up words in a dictionary by the association of component flags with each possible constituent word within the misspelled compound word as well as with the possible replacement candidates for each letter string between these possible constituent words, and by the application of powerful tree-scanning techniques that isolate the possible components of a compound word and determine their correctness in isolation and association of each other.

Abstract: Calcium-urea nitrate [Ca(NO₃)₂.4CO(NH₂)₂] is produced by means of a process, according to which: 
- a liquid composition is prepared, at a temperature not higher than 170°C, which contains urea and calcium nitrate, in a molar ratio to each other equal to, or approximately equal to, 4/1, and having a water content comprised within the range of from 0 to 15% by weight; 
- said liquid composition is sprayed, through a spray nozzle, on previously formed solid particles of calcium-urea nitrate, kept moving at a temperature comprised within the range of from 40 to approximately 100°C, and under a stream of an inert gas; 
- calcium-urea nitrate is recovered from said solid products from the spray. 
     The so obtained calcium-urea nitrate is in the form of a granular and free-flowing solid, free from the tendency to form dusts, and is useful in agriculture as a nitrogenous fertilizer. 
     Also the suitable equipment for carrying out the process of calcium-urea nitrate preparation as a continuous process is disclosed.

Abstract: A vibration isolating and damping suspension strut (38) for vehicle undercarriages comprising an elongated cylinder (48) and piston (62) structure wherein the cylinder (48) is divided into opposed chambers (64, 66) which are in communication with each other by passages (96)formed in the piston (62) and in a flow restricting shuttle valve (100) mounted on the piston rod (68). When the strut (38) undergoes a retraction stroke of the piston (62) to absorb loads silicone fluid is compressed in the opposed chambers (64, 66) and transferred from the chamber (64) opposite the piston rod (68) to the rod side chamber (66) through passages (96) in the piston (62) only. When the strut (38) rebounds or ex­tends its piston rod (68) fluid is forced to flow through passages in the shuttle valve member (100) and the piston flow passages (96) at a more restricted rate. This piston flow passages (96) and the shuttle valve (100) are arranged to direct fluid flow toward the outer cylinder borewall (56) to improve heat transfer to the ex­terior of the strut (38) and minimize heating of the fluid contained in the cylinder chambers (64, 66). Alternate embodiments of the suspension strut have spiral fluid transfer grooves formed on the periphery of the piston or on a cylinder sleeve insert member.

Abstract: A driver circuit that is responsive to an input AC (24) voltage provides a drive signal to a load circuit (12), such as, a solenoid coil, for each actuation of a switch (51). A sine wave shaper (28) produces a positive edge delayed square wave timing signal for a continuously clocked flip-flop (18). In response to the switch actuation, the clocked flip-­flop (18) generates a control signal for a selected period of time that is related to one cycle of the AC input voltage. The selected period of time occurs only during the positive portion of the input AC voltage cycle. The control signal is employed to generate the drive signal for the load circuit. The driver circuit provides switch bounce rejection equal to one cycle of the AC input voltage.
