Abstract: IMPROVED POLYNUCLEOTIDE SYNTHESIZER AND METHOD                 ABSTRACT        There is disclosed a polynucleotide synthesizer and a method of using it.  The synthesizer comprises supply means for supplying a) liquid reactants for synthesizing peptides or polynucleotides, b) liquid reagents that assist in the synthesis, and c) a wash liquid; a reactor column; connecting means for fluidly connecting the supply means with the column; means for positively displacing with gas pressure, liquid reactants and reagents, and wash liquid from the supply means into the connecting means; and controlling means connected to the column for allowing liquid to flow under the force of the gas pressure and at a controlled rate, into a temporary storage chamber and for thereafter emptying the chamber.  The synthesizer is improved in one or both of the following features:  In one aspect the controlling means is fluidly positioned only downstream of the reactor column, and the synthesizer further includes means preventing flow from the controlling means back to the column, whereby the column is precluded from contamination by reactants or reagents in the controlling means, and the controlling means needs no cleaning to prevent it from contaminating the column.         In another aspect the synthesizer further includes a parallel manifold having i)  sufficient inlet means to receive either each of the liquid reactants or each of the liquid reagents, ii)  a common inlet to receive the wash liquid, and iii)  an outlet connected to the connecting means to supply reactant or reagent to the column or to the controlling means, each of the inlet means including a pair of tandem two-way valves, both of the valves of the pair having a common outlet that feeds into the manifold outlet, one portion of each pair of the tandem valves being connected to the common inlet for the wash liquid and the other portion of the valves being connected to the inlet means for one of the liquid reactants or one of the liquid reagents, and means for selectively opening one of the pairs of valves at a time to a source of wash liquid, in a predetermined sequence, whereby an adequate source of wash liquid can be provided for each of the valve pairs of the parallel manifold.           The method features the steps of a) drawing under the gas pressure a reactant from a source of supply first into an outlet common with all reactants, then into the column, and then into the controlling means, b)   drawing under gas pressure a wash liquid through the common outlet, then into the column and then into the controlling means, c)   and ejecting all liquid out of the controlling means into either a collection container or a waste disposal without passage through the column.

Abstract: ABSTRACT         The invention herein discloses an improved and unique new sprayer implement for spraying crops.  The sprayer comprises two wing booms, a left and a right which are controlled independ-ently from one another by hydraulic cylinders.  The sprayer is capable of maintaining one wing boom in the transport position while the other main wing boom is extended transversely to the direction of travel in the operating position therefore allowing the operator to spray with one side of the sprayer only.  This allows the operator to have access to areas of a field where he would not normally be able to work with a wide sprayer.  The sprayer is also equipped with an anti-damage locking system where-by a resilient spring or shear pin is released when either one of the main wing booms strikes an obstacle such as a tree or power pole.

Abstract: For printing fine patterns, a fine pattern of a setting type ink is applied to a printing plate surface to become printing elements.  Then, the setting type ink thus applied on  the  printing plate  is  subjected  to a setting treatment thereby to set at least one part of the ink pattern,  and  thereafter  the printing plate and an object to be printed are pressed relatively against each other thereby to transfer the ink pattern onto the print object.  The printing plate can be an intaglio plate or a lithographic plate.   Fine patterns of printing element widths as fine as 3 µm with an ink film thickness of 2 µm can be printed efficiently with high precision on various objects including hard and rigid objects.

Title: Rate adaptive pacemaker controlled by ejection fraction
Inventor: CHIRIFE RAUL
IPC: A61N1/365
Filed: 1992-04-14
Granted: 1998-07-07
Abstract: A rate adaptive pacer designed to accommodate changes in a patient's metabolic demand utilizes ventricular ejection fraction (EF)  as the rate controlling parameter.   Ejection fraction is measured by sensing intracardiac impedance at end-diastole and end-systole and then using these measurements to compute stroke volume (SV).  Ejection fraction is the stroke volume divided by the end-diastolic volume.  This calculated value of EF is processed by the pacemaker to determine the escape interval (pacing rate) through a simple conversion algorithm.
