Title: Rapid charging of batteries
Inventor: BURKETT WILFORD BENSON
IPC: H02J7/00
Filed: 1970-10-19
Abstract: 1293984 Battery charging systems McCULLOCH CORP 19 Oct 1970 [20 Oct 1969] 49513/70 Addition to 1219324 Heading H2H Apparatus for rapidly charging an electric battery comprises a source of charging current and a discharge path connected across the battery each time a predetermined charging condition is reached, the discharge path including circuit means for coupling the energy in the discharge path to the charging source. Closure of a switch 67 energizes a transformer 62 such that during positive half cycles a battery 71 is charged from a winding 64 by way of a thyristor 70, the charging current initially flowing by way of diode 75 and resistors 76, 77 until the thyristor fires when a heavy charging current flows therethrough to the battery. During the same period a pulsating current i 1  flows in a resistor 72 from a secondary winding 65 by way of a resistor 73 and a diode 74, thereby maintaining a second thyristor 80 non-conductive. As the charging process proceeds, the battery terminal voltage increases until, during the negative half cycles of the supply when the battery voltage is applied to the serially connected resistors 77, 72 and a zener diode 78 the zener diode breaks down and a current i 2  flows through the resistor 72. This produces a signal which when applied to the gate of the thyristor 80 causes it to become conductive to establish a discharge path for the battery which includes a resistor 79 and a winding 66 on the transformer 62 whereby the discharge energy from the battery is coupled back to the A.C. source 60, 61. During the next negative half cycle the thyristor 80 becomes non-conductive and the discharge path removed. In other embodiments the discharge of the battery is initiated in response to the temperature or the internal gas pressure of the battery.

Abstract: 1282966 Distillation of mine drainage water WESTINGHOUSE ELECTRIC CORP 19 Oct 1970 [10 Nov 1969] 49544/70 Heading BIB Purified water and a disposable residue are obtained from mine drainage water by passing it, via conduit 16, through a multi-stage flash evaporator 10 to obtain purified water as distillate and an enriched brine, passing enriched brine, via conduit 70, through a second multi-stage flash evaporator 12 in which additional purified water is separated from the brine, and submitting the concentrated brine to evaporation in a single-stage plant 14 to obtain a slurry which is drawn off through conduit 24 and can be cooled to obtain a solidified compact mass whose volume is less than 1 of the volume of the original #100 mine drainage water. Each of the evaporators 10, 12 and 14 is of the recirculation type. In evaporator 10, some of the enriched brine reaching the last flash chamber 38 is pumped to evaporator 12 and the remainder is mixed with deaerated feed water in chamber 36. When the system is started up, the water is seeded with crystals of CaSO 4 .2H 2 O in an amount of about 4 pounds of crystals per 100 gallons (U.S.) of water. Sections 26 and 142 of evaporators 10 and 12, and the condenser 192 of evaporator 14, are cooled by heat-exchange conduits through which water from a cooling tower (not shown) is circulated. Section 28 of evaporator 10 is deaerated by an ejector (not shown) attached to the outlet 122. Air is withdrawn from section 26 through outlet 74.

Abstract: 1515880 Lasers COMMISSARIAT A L'ENERGIE ATOMIQUE 11 Dec 1975 [23 Dec 1974] 50813/75 Heading H1C To permit adequate population inversion replenishment from reserve energy levels in a laser amplifier in which a pulse from a laser oscillator 2 is passed repeatedly through an amplifying medium 8, the repeated passes are effected by a group of encircling mirrors M 1 , M 2 , M 3  ..., arranged to transmit the pulse through the active medium in such manner that any given portion thereof only amplifies a pulse during alternate passes. In both arrangements described the incident beam from the oscillator 2 is of rectangular cross-section, the mirrors M 1 , M 2 , M 3  ... are rectangular and plane or slightly concave, and the active medium consists of a CO 2 , N 2 , He mixture having a right circular cylindrical active region 8 in which the energy level population is inverted. In Fig. 2 the pulse incident beam passes through one half of the cylindrical region 8, is reflected by mirror M 1  to pass through the other half of the cylindrical region, and is then repeatedly reflected by the ring of mirrors M 2 -M 15  in turn through alternate active region halves until the beam is passed out of the ring by the absence of a mirror opposite M 15 . In an alternative embodiment, Fig. 3, the pulse incident beam passes through the whole of the active region 8, and is then reflected by a ring of mirrors M 1 -M 6  so as to pass through and react with the region only during alternate passes of the beam. The active medium may be excited by gas discharge between disc electrodes and be preionized by an electron beam. The active gas may be contained in the cylindrical region defined by the electrodes by providing a wall which is unsealed just before an incident pulse is received by the amplifier, or the gas may fill a chamber which includes all the mirrors.
