Title: Water purification and sterilization - using chlorination and flocculation by ferrous cpd(s) in reverse order to normal or simultaneously
IPC: C02F1/52
Filed: 1974-08-23
Abstract: The quantity of active chlorine used is sufficient to overcome the reaction threshold and reacts with the ferrous salt(s) to form other ferrous cpds. The flocculant salt(s), the optional oxidn. promoter and the source of active chlorine may be added simultaneously esp. as a premixt., or the source of active chlorine added after the other agents. The ferrous salt used is esp. ferrous chloride, the oxidn. promoter is HCl in stoichiometric quantities relative to the ferrous chloride and the source of active chlorine is sodium hypochlorite. When the last is added after the other additives, the pH value of the finished prodt. is 7.5-8; when all agents are added as a premix simultaneously, the pH value is 6-7, esp. 6. There is significant improvement esp. in terms of pH control compared to conventional method where active chlorine source is added before the flocculant(s).

Title: Method of assessing viability of seeds - involves passing electrical current through partially germinated seed
IPC: A01C1/02
Filed: 1974-09-11
Abstract: The method is for assessing the viability of seeds, such as peas. It is particularly related to giving results applicable to growing in open ground. Dry seeds are kept moistened for a period of time and at a temperature which allows them to pass into the first phase of their germination cycle, but without starting the final phase. An electric current, at a constant voltage, is passed through each seed and measured and the seeds separated into groups according to the observed current values; the viability being related to current flow. The max. current and voltage required are about 40 mu A and 1.5V respectively.
Patent FR-2263546-A1 (FR)
IPC: G04G3/02
Filed: 1974-11-19
Abstract: Disclosed is a circuit for generating in a pulse motor drive coil an initial pulse motor drive pulse in a unit length of time during which a second hand is driven by one step, after resetting for time correction has been released. The output of a divider chain for frequency-dividing a standard frequency signal from a quartz oscillator into a signal having a period equal to the unit length of time is delayed by a delay circuit, and by a logic gate responsive to the output of the delay circuit and the output of the divider chain there is produced an output pulse signal having a period equal to the unit length of time and a narrower width. The output of the logic gate is supplied to a binary counter. An output circuitry responsive to the output of the binary counter and the output of the logic gate generates drive pulses in the drive coil. The reset signal is applied to the delay circuit and at least a frequency divider stage producing the signal the period of which equals the unit length of time.

Title: Register for touches in childs fencing game - contact between foil and register plate triggers thyratron to give displayed signal
IPC: A63B69/02
Filed: 1975-01-31
Abstract: Each foil is connected to a thyristor circuit, as is a register plate worn by each peron. When a foil (FA, FB) touches the other person's plate (PA, PB) a circuit is formed. A thyristor (13) is triggered and a condenser (19) charges across a signal lamp (12) and a transistor (18) potential rises to illuminate this lamp. If a switch (21) is closed, a buzzer (15) sounds. The lamp remains alight whilst the capacitor charges. When this is completed, the transistor is blocked since no current flows and the system returns to its state of rest. No touches are registered by either person until the signal lamp goes out.
