Inventor: GEISLER THOMAS C
IPC: C09B67/00
Filed: 1982-03-26
Abstract: A stabilizing agent for use in electron donor-acceptor carbonless copying systems. The stabilizing agent is 2,2'-methylene-bis(4-methyl-6-t-butyl phenol). Systems in which the stabilizing agent is useful comprise a color-forming composition comprising at least one leuco dye which is fadeable or discolorable after development, a color-developing composition comprising an acidic coreactant material capable of reacting with the color-forming composition to provide colored products, and the stabilizing agent. The stabilizing agent prevents discoloration or fade of images produced by reaction of the color-forming composition with the color-developing composition. In a preferred embodiment, the color-forming composition additionally comprises dithiooxamide and/or dithiooxamide derivatives, the color-developing composition additionally comprises a transition metal ion capable of reacting with the dithiooxamide compound to produce a purple-colored product, and the reaction of the color-forming composition with the color-developing composition results in a neutral balclack colored product.

Abstract: Method for measuring the camouflaging capacity of a smoke. A selected radiation source, such as an IR radiation source, is divided into a predetermined number of IR radiating elements (0-7) having mutually differing radiation temperatures. After the release of smoke between the radiation elements and an IR camera, the number of temperature peaks which cannot be distinguished with respect to the background temperature is employed as a measure of the IR camouflaging capacity of the smoke. When measuring the camouflaging capacity of the smoke over a wide area several groups (21-26) of such IR-radiating elements (28, 29) are distributed over the area.

IPC: H02M3/337
Filed: 1983-07-05
Abstract: The present invention synthesizes an approximation to a 60 Hz sine wave using a plurality of bursts of high frequency square waves. The number of square wave cycles in each burst is modulated to achieve a good approximation to a sine wave. This bipolar burst train is then separated into two complementary unipolar burst trains, which are fed to power transistors to modulate current at the primary of a transformer. Since the transformer is not required to withstand saturation over a full half cycle at 60 Hz, but only over a half cycle at the square wave frequency, the transformer weight can be greatly reduced, as can the number of primary turns. Two secondary windings are used, each coupled to a single output stage, and an npn/pnp pair of transistors, controlled by the 60 Hz reference, provides polarity switching to restore full-cycle ac output power.

Abstract: A method of printing an analog waveform having a time variable, such as an ECG by first converting the analog waveform into a time sequence of digitally expressed values, forming predetermined groups of digital data and then determining maximum and minimum amplitude values of the digital data within the groups. These values are stored in a line buffer memory. A recording medium advances past a transversely oriented a linear array of discrete recording elements, such as linear array dot printhead. The serial stored values are read out in parallel to each of the recording elements, with the elements actuated in parallel by the stored values at an initial time and for time durations for each element that is a function of the stored maximum and minimum amplitude values for that element. The waveform is recorded as a series of appropriately placed short parallel longitudinal lines to form in aggregate a transverse waveform display on the recording medium.
