Patent FR-2443164-A1 (FR)
IPC: H03H9/215
Filed: 1979-10-23
Abstract: Cutting a quartz tuning fork crystal vibrator at a preferred angle and with a thickness which establishes a close coupled relationship between the flexural and torsional modes of vibration of the arms or tines produces a vibrator having a highly favorable cubic frequency temperature characteristic at predetermined frequencies. Weight added to the ends of the vibrating tines reduces the frequency of both flexural and torsional vibration, whereas weight added at nodal points in the flexural vibration primarily reduces only the torsional vibrational mode. Accordingly, a wide range of frequency adjustments is possible. Deviations from the desired crystal operating frequency due to manufacturing variances are adjustable by sequential weight modifications while the desirable cubic temperature characteristic is retained. High accuracy over a wide temperature range permits operation in oscillator circuits at relatively low frequencies and with attendant low power consumption. Close coupling between vibrational modes occurs when the difference between the flexural and torsional frequencies is </=0.15 of the flexural frequency. The principles for dimensioning the crystal, and adjusting thickness and weight, are applicable to both fundamental and overtone frequencies.

Title: Recycled water system with controlled concn. of impurities - automatically closes drain valve before additive pump operates
Inventor: GABET A
IPC: G05D21/02
Filed: 1980-12-04
Abstract: The circuit is of the type in which the concn. of impurities increases progressively during circulation of the water, e.g. in the cooling water circuit of an atmospheric condenser in a refrigeration system. A programmable controller is linked to an incremental flow-meter on the water make-up supply, an additive metering pump, an additive tank agitator and a circuit discharge to drain valve. The controller prevents pump operation when the discharge valve is open. Pref. the additive metering pump delivers in direct proportion to the increments signalled by the flowmeter. Pref. the opening of the discharge valve is triggered volumetrically. Pref. the agitator does not operate while the pump is working. Since the discharge valve is closed while additives are pumped in, the amt. of freshly injected additives lost to drain is greatly reduced. Since the agitator does not operate during pumping, concentrated pockets of additive are not directed into the pump. The level of additives is accurately maintained so that rusting and scale formation in the circuit are avoided.

Title: Switched capacitor discharge sampled signal attenuator - has memory capacitor charged as function of attenuation under control of sequencer, and partial charge sampling circuit
Inventor: TESTARD ROBERT
IPC: H03G1/00
Filed: 1980-12-19
Abstract: A capacitor stores sampled input signals, and is partially discharged to produce an attenuated output. The attenuation on a dB scale is linearly proportional to the discharge time. The input signal is filtered and band limited to 300-3400H2 to prevent aliasing (21) and the impedance is lowered by a differential amplifier (20). The gating of the memory capacitor (C) is at 8KH2 synchronised to the PCM coder clock. The voltage on the capacitor is read by a voltage follower buffer amplifier (22) to a PCM coder, and is not gated since it is sampled in the PCM coder. The capacitor and discharge resistor are chosen such that the capacitor is completely discharged in 4 micro seconds, charged completely in 8 pico seconds and partially discharged by 1dB in a half period of 512 KH2. A synchronised controller sequentially gates the input onto the capacitor until it is charged, partially discharges it for a selected period, the remaining signal is readout, the capacitor is completely discharged and the sequencer re-cycles.
