Abstract: A tellurium-containing cathode for nonaqueous cells employing tellurium in the +4 oxidation state such as TeO.sub.2, Te.sub.2 MoO.sub.7, TeO.sub.2.xBi.sub.2 O.sub.3 wherein x is from 0 to about 8, Sb.sub.2 TeO.sub.5 and Sb.sub.2 TeO.sub.7.

Abstract: An improved latching-type comparator operative in a selected one of two exclusive states is disclosed. In one state, the operational state, a gain stage is rendered operative to amplify at least one intermediate current signal generated by an input stage in response to the comparison of a pair of input signals. At least one drive current signal is generated by the gain stage in response to the comparison and is buffered by a corresponding buffer stage to render both an output signal and a signal representative thereof. In the other state, a latch stage is rendered operative unresponsive to the comparison and governed by the signal representative of the output signal to sustain the drive current signal in a state to latch the output signal. A switching stage governed by at least one latch signal effects the selection between the gain and latch stages by conducting operating current exclusively from the selected stage to a constant current stage.

Abstract: A nonaqueous cell employing a manganese dioxide-containing solid cathode having a minor amount of an alkali metal or an alkaline earth metal additive such as Li.sub.2 SiO.sub.3, Li.sub.2 B.sub.4 O.sub.7, Li.sub.2 MoO.sub.4, Li.sub.3 PO.sub.4 or Li.sub.2 WO.sub.4 to suppress the build-up of internal impedance in the cell during storage and discharge that may occur with electrolyte degradation.

Abstract: A sulfide-containing cathode for nonaqueous cells such as AgBiS.sub.2, Co.sub.2 Bi.sub.2 S.sub.5, CoBi.sub.2 S.sub.4 and FeSb.sub.2 S.sub.4.

Abstract: A solid cathode for nonaqueous cells comprising complex metal sulfides such as PbFeS.sub.2, Co.sub.0.5 Fe.sub.1.5 S.sub.2, Co.sub.1.5 Fe.sub.0.5 S.sub.2 and CoFeS.sub.2.

Abstract: A nucleonic gauge (10) is disclosed for effectively assessing the amount of lubricating fluid in a hinge joint (12) having an elongate reservoir (23) without disassembly of the joint. The gauge includes a disc-type radiation source (54) at one end of the joint for emitting radiation cooperatively with respect to the lubricant reservoir and providing a substantially collimated beam pattern (60), and a detector element (64) in the path of the pattern at the other end of the joint for measuring the radiation activity.

Abstract: A solid cathode material comprising the reaction product of metallic bismuth, metallic sulfur and metallic iron or metallic lead for use in nonaqueous electrochemical cell systems using active anodes, such as lithium, and organic electrolytes, such as electrolytes based on 3-methyl-2-oxazolidone in conjunction with a cosolvent and a selected solute.

Abstract: A solid cathode material comprising the thermal reaction product of bismuth trioxide and molybdenum trioxide for use in nonaqueous electrochemical cell systems using active metal anodes, such as lithium, and organic electrolytes, such as electrolytes based on 3-methyl-2-oxazolidone in conjunction with a cosolvent and a selected solute.

Abstract: A solid cathode material for electrochemical cell systems comprising the thermal reaction product of bismuth trioxide and tungsten trioxide.

Abstract: A new class of compounds having fabric softening properties is formed by hydroxamic betaines having the general formula R.sup.1 (R.sup.2)(R.sup.3)N.sup.+ -- R.sup.4 -- CO -- NH--O.sup.- in which R.sup.1, R.sup.2, R.sup.3, R.sup.4 are hydrocarbon groups having i-25 carbon atoms with the proviso that the betaine contains not more than 45 carbon atoms, at least one carbon chain of at least 12 carbon atoms and the carbon chain of R.sup.4 between the quaternary N-atom and the CO-- group is no longer than 4 carbon atoms. The compounds, which can be used in a fabric softening rinse composition as well as in a detergent composition, remain in dispersion during the washing process, but deposit onto the fabric when the pH decreases during subsequent rinsing.
