Title: Alkaline accumulator using zinc:cadmium alloy as negative electrode - esp. where electrolyte is potassium hydroxide soln., and second electrode is nickel
Inventor: DIARD JEAN-PAUL
IPC: H01M4/24
Filed: 1979-10-24
Abstract: The Zn-Cd alloy pref. contains 90-17.4% Zn, and esp. 90-70% Zn. Two esp. pref. alloys contain (a) 50% Zn; or (b) the eutectic contg. ca. 17.4% Zn. The pref. accumulator contains an electrolyte which is a KOH soln. contg. no potassium zincate; and also a second electrode which is made of Ni or an Ni deriv. The accumulator is used esp. for electric traction. Alkaline Ni/Cd accumulators have a better energy:wt. ratio than Pb accumulators, and this ratio is further increased if the Cd is replaced by Zn, which is lighter and less expensive. The Zn increases the voltage at the terminals, and raises the electromotive force. Unfortunately, however, the oxidn. prods. of the Zn dissolve in the KOH electrolyte and impair the performance of the accumulator, esp. by depositing Zn in the form of dendrites causing short circuits between the two electrodes. The object of the invention is to prevent the dissolution in the electrolyte of the oxidn. prods. of Zn formed during discharge of the accumulator, and also to prevent the formation of dendrites.

Title: Error detection loop for linearity correction circuit - uses two directional couplers, delay line and error signal extracting circuit connected to amplifier output
IPC: H03F1/32
Filed: 1979-11-14
Abstract: The error detecting loop, isolates errors introduced into a signal by an amplifier so that they can be subsequently reinjected out of phase to cancel the error in the output and restore the signal to linearity. The input signal is fed through a directional coupler to an amplifier, is amplified and phase shifted. A second output from the coupler is delayed to introduce the same phase shift as the amplifier. A proportion of the amplifier output is tapped off by a second directional coupler and a weighted sum of it and the delayed reference is the error signal if the potentiometer summing the output is chosen so that the input signal is cancelled.
