Abstract: Capacitor Discharge Ignition System For Internal Combustion Engines Abstract The invention provides a modular ignition system using a separate ignition module (16) for each engine cylinder.  The modules (16) can be arranged for use with engines having differing numbers of cylinders. Each module (16) includes a main capacitor (22) to be charged by the engine's alternator (11).  The main capacitor (22) is discharged through a main silicon controlled rectifier (23) into an ignition trans-former (28) to provide a high voltage pulse to fire a spark plug (15).  A pilot capacitor (26) is also charged by the alternator (11) to provide power to a pilot SCR (36).  The pilot SCR (36) has its gate connected to a trigger winding (14) in the alternator (11) to discharge the pilot capacitor (26) into the gate of the main SCR (23) to fire the spark plug (15).  The pilot capacitor (26) is also connected to the cathode of the main SCR (23).  This connection raises the voltage level of the pilot capacitor (26) during the discharge pulse to assure gate current to the main SCR (23) during the critical turn on period. A biasing network including resistors (39,40) and a bias capacitor (41) is provided in each of the modules (16) to maintain a substantially constant ignition angle, regardless of engine speed.  The biasing networks can be interconnected to assure uniform timing for all of the spark plugs (15).

Abstract: ALKYLAMINOPHOSPHONIC CHELATING RESINS, THEIR PREPARATION AND USE IN PURIFYING BRINES     ABSTRACT New   macroporous   alkylaminophosphonic   chelating resins which exhibit excellent mechanical stability and strength and good chemical stability are characterized by having  an  apparent  density  of  0.35  to  0.425  g/ml,  a granulometry smaller than 0.8 mm, a water retention of 50 to 60 percent in the acid form, a porosity of 800 to 1100 mm3/g, a total theoretical capacity for the fixation of calcium ions of not greater than 31 g/l of resin in the sodium form and an osmotic resistance such that more than 90 percent of the beads are intact after 30 shocks.  The high resistance to osmotic shock combined with an adequate exchange capacity exhibited by the new resins makes them particularly  suitable  for  use  in  highly  concentrated solutions, such as concentrated electrolytic brines.      A simple,  effective,  and economical procedure  is described which makes it possible to eliminate,  in the form of complexed cations, the impurities contained in the brines used for the electrolytic production of chlorine or alkali metals in membrane cells or diaphragm cells and for the electrolytic production of chlorates.

Abstract: TITLE OF THE INVENTION  "METHOD AND APPARATUS FOR ERROR CORRECTION"                      ABSTRACT OF THE DISCLOSURE        A method of error correction comprises error correction coding processing and interleaving and de-interleaving  proces-sings for digital subcoding data (as opposed to main data) in subchannels (as opposed to the main channel) to be transmitted.          Apparatus is provided comprising means for performing those processings.  The method for error comprises the steps of dividing digital subcoding data in one PACKET into a plurality of PACKs; adding a first redundant code for error detection or error correction to each of the PACKs; and interleaving the digital subcoding data in each of the PACKs and the first redundant code; whereby the interleaved data is transmitted together with frame sync signals and main data.  The data in the subchannels is coded and interleaved and then recorded so that the distances between the data are maximized.  Therefore, if errors should occur, the interpolation can be properly done, thereby improving the error correcting ability without requiring complicated error correction circuit or large buffer memory such as those required for the data in the main channel.

Abstract: ABSTRACT        A porous sintered metal chromatographic column terminator element is disclosed comprising a relatively low denisty central disc portion, an intergral relatively high density rim portion peripherally circumscribing the central portion and an interface zone that intergrally joins the rim and central portions.  The relatively flat faces of the rim and central portions are essentially coplanar but are separated and delineated by a channel at the surface of the interface zone intermediate said co-planar faces.  The intergral porous element exhibits a permeability ratio between the central disc portion and the rim portion of at least 3:1.  Additionally, the central portion exhibits a density up to about 70 percent of the density of solid material of the same composition while the density of the rim portion is greater than that of the central portion and is up to about 95 percent of that of solid material of the same composition.  The outer rim of the element provides an excellent seal with the packed tube of the chromatographic column to prevent side leakage. At the same time the element achieves improved efficiency of the chromatographic column.

A vertical belt unit is provided which is comprised of two belts which travel at a speed lower than said predetermined fixed speed.  The two belts are separated by a distance which is flexibly adjustable to the width of the articles. The belts slow down articles moving on the conveyor and separate them by a predetermined distance from one another when the articles leave the belt unit.  The invention can further include a pusher which removes the articles, in a perpendicular manner from the conveyor.  A second conveyor is located at the output of the pusher and travels at the same speed at the pusher to provide a smooth transition of articles through a perpendicular change in direction.

Abstract: ABSTRACT OF THE DISCLOSURE    Apparatus for measuring the absolute reflectance of a sample, which comprises an integrating sphere provided with four windows the centers of which lie in a plane including the center of the integrating sphere.  A first one of the four windows has its center coinciding with a diametrical line of the integrating sphere included in the plane while a second and a third window are arranged symmetrically with respect to the diametrical line, with a sample set in the fourth window so as to face inwardly of the integrating sphere.  A light source is so arranged as to introduce a beam of light into the integrating sphere and a light measuring device is so arranged as to receive the light emerging from the integrating sphere.  The integrating sphere is rotatable for 180° about an axis coinciding with the above-mentioned dia-metrical line so that the integrating sphere selectively takes two positions thereby to change the operative positions of the second and third windows relative to the light source or the light measuring device.  The data measured at each of the two positions of the integrating sphere are processed so as to obtain the absolute reflectance of the sample.  The positions of the light source and the light measuring device relative to the windows of the integrating sphere may be exchanged to obtain a different type of absolute reflectance.

Abstract: REGULATED CURRENT SOURCE FOR THERMAL PRINTHEAD              Abstract of the Disclosure A current-drive circuit (Fig. 1) is provided to drive each of forty electrodes 41.  Voltage at the electrodes 41 is monitored on line 49 as a control-input to a voltage-regulator circuit (Fig. 2), to produce the drive voltage Vdr.  Vdr minus a current-level reference Vlev is applied as the input of a differential amplifier (transistors 3, 15, 51 and 53), thereby applying Vdr-Vlev on line 27.  A constant current through the electrode 41 is produced across register 25.  As the lowest voltage at all driven electrodes shifts, the regulator circuit (Fig 2) shifts Vdr the same amount, employing differentially connected transistors 72 and 74, and Zener 120 to set the level of Vdr.  Since most of the active elements operated within narrow limits, the circuit can be extensively miniaturized.
