Title: Indicating circuit for defective electric fuses - for use with electroluminescent diode, increases reliability
IPC: H02H3/04
Filed: 1973-06-06
Abstract: The circuit consists of a battery (B) with voltage not less than 80 Volts, to which are connected various loads (U1 to U12) and fuses (F1 to F12). Each fuse, typically (F1), is connected to the negative terminal of the battery and in series with diode (D1) and resistor (R1). A zenor diode (Dz) is connected to a common point of all the fused circuits and to the negative terminal of the battery. A circuit (1) common to all the fused circuits can detect a faulty fuse as follows. When a fuse, typically (F1), is open-circuited, a circuit is made from the positive terminal of the battery through load (U1), diode (D1), resistor (R1) and Zenor diode (Dz) to the negative terminal of the battery. The transistor (Q) conducts and saturates to supply diode (DS) which lights up then giving an indication of the fault. Transistor (Q) can also excite relay (AL) and contacts (01, 02, 03) are then closed and supply (V) which can be a remotely located alarm or a light.

Title: Nuclear reactor instrumentation system - for measurement of reactivity and Eigen-value
IPC: G21C7/00
Filed: 1973-07-12
Abstract: Two sets of neutron detection instruments are placed within the core and used to measure neutron fluctuations which are represented electrically as noise signals. Initially, to calibrate the measurement system, the measurements are taken with the reactor running critical and the signals are passed through narrow band filters of identical centre frequency to a comparator feeding a computer in which a coherence function is calculated following a given formula based on statistical mean probabilities of coincidence and non-coincidence over the period of the measurement. A curve is then plotted starting from that point with different centre frequencies to derive the narrow-band filtered coherence curve. When the reactor is running operationally, the same noise signals are passed to the computer this time through wide band filters and the computer, produces continuous read-out of the reactivity using a formula also including as well as the asymptotic value, derived from the calibration curve of the coherence function, the measured coherence function calculated in the computer using a similar probability formula. The computer can also calculate standard deviation of reactivity.

Title: Gear drive for linear correction in barometric indicators - uses teeth with pitches which vary in predetermined non linear manner
IPC: G01D5/04
Filed: 1975-11-28
Abstract: One of the gear wheels which is mounted in the correction transmission has teeth pitches which varies according to the pre-determined non linear law to which the angular speed is to be varied.

Title: Cleaning filter with filter cell in vessel contg. charge - with periodic cell rotation effecting cleaning by centrifugal action
IPC: B01D29/00
Filed: 1976-02-12
Abstract: Process comprises rotating the cell in the body of the liq. being filtered, at a rate great enough for the liq. in the cell to be driven through the filter wall by centrifugal force.

Holes in the shaft above the lower plate allow air to enter the shaft while sufficient liq. remains in the cell for cleaning. The cleaning can be effected without deterioration of the filwer wall and without the necessity of returning any filtrate to the filter.
