Title: Cathode active material for alkaline accumulators - comprising magnetite with added zinc metal or oxide and PTFE binder
Inventor: DAUCHIER JEAN-MICHEL
IPC: H01M4/24
Filed: 1980-07-31
Abstract: Electrode comprises an active material based on iron, pref. magnetite, with the addn. of Zn or ZnO in an amt. of 5-15% Zn and up to 10 wt.% binder, (pref. 2% PTFE). The electrode is used as cathode in an accumulator using as anode nickel (hydr)oxide, and as electrolyte, KOH soln. Accumulators using this cathode do not suffer the same inconveniences as the electrode of the 1950 modification of the Edison accumulator which utilised dendritic copper which while improving behaviour under rapid discharge, caused poisoning of anode if it was allowed to get into soln. in the electrolyte, and by virtue of its wt. lowered the specific capacity of the active mass.

Title: Determining gold content of mined rock - by irradiation with neutrons and measurement of intensity of resultant gamma rays produced by gold reaction
Inventor: CLAYTON COLIN GEOFFREY
IPC: G01N23/222
Filed: 1980-12-08
Abstract: The gold content of gold-bearing material is determined by irradiating the material with neutrons. The reaction Au-179 (nn') Au-179 m takes place, producing gamma rays of energy 279 keV. The intensity of the gamma rays is measured and gives an indication of gold content. The method is used for selecting samples of gold-bearing ore for further treatment and extraction. The method can cope with a high throughput of material, and is accurate since a property of the gold itself is used as an indication.

IPC: B60C9/26
Filed: 1981-02-09
Abstract: The invention relates to crown reinforcement for pneumatic tyres, in particular for radical tyres, which reduces the problem of the angular effect in tyres. The crown reinforcement contains three layers (7, 8, 9) which each consist of parallel cords produced from the same material, the central layer (8) and the layer which is the radially innermost one (9) each being folded along an edge and the radially outermost layer (7) being cut and unfolded. The folds (10 and 11) are attached on opposite sides of the central circumferential face of the crown reinforcement and the radially innermost layer (7) overlaps the inner extremities of the folded edge sections (8a and 9a) of the central layer and the radially innermost layer. Preferably, the cords of the layers are produced from non-stretchable and non-compressible material such as for example steel. Preferably, the radially outermost layer (7) overlaps the inner extremities of the unfolded edge sections (8b and 9b) of the central and the radially innermost layers. Preferably, the crown reinforcement (5) is symmetrical with respect to its central circumferential face.

Title: Knocking control circuit for IC engine - has several engine-mounted sensors supplying control stage via multiplex switch with working cycle related to crankshaft speed
Inventor: ROHDE SIEGFRIED
IPC: F02D41/22
Filed: 1981-02-17
Abstract: Several knocking sensors are mounted on the i.c. engine and connected to a control regulating at least one working characteristic. The signal outputs of the separate sensors (22-25) are coupled via a multiplex switch (26) to a pinking control stage (15) constituting part of the control appts. The operating cycle time of the switch (26) has a fixed ratio w.r.t. the rotational speed of the crankshaft. Starting from the pinking control stage (15), the regulating values of one or more cylinders can be individually adjusted. The regulating values can be for ignition time points (20) and/or mixture supply (13) in the case of Otto engines and start of fuel injection for Diesel engines. The evaluating electronics is single channel, reducing the number of electronic components required.

Title: Attenuation measuring system for transmission line - uses exponential and logarithmic amplifiers at input and output respectively to determine attenuation factor
Inventor: MARTIN JEAN-LOUIS
IPC: H04B10/07
Filed: 1982-01-15
Abstract: A transmission line (10), e.g. fibre-optic coaxial cables, etc., whose attenuation is required is connected between transmission (20) and receiving (30) units. The transmission unit contains an amplifier (22) configured to generate an exponential signal from an analogue or digital information signal applied to the input. At the receiver a low noise amplifier (31) with constant gain (G) provides an output for a log. amplifier (33) whose second input is a constant current level equal to the amplifier gain. This amplifier thus reconstitutes the original signal and provides the logarithm of the line attenuation. The amplifier output is applied to a capacitor (C1) across which a display (35) is connected to read out the attenuation. The receiver output (R) can be used for automatic gain control purposes.
