Abstract: A minimum noise design is achieved by setting the coupling a factor (Q e1 ) on the input side of an amplifier 18, the coupling Q factor (Q e2 ) on the output side of the amplifier 18, and the gain G of the amplifier 18 so that they satisfy the condition that            Q       e1            < Q       e2            and 1/Q       e1            = G/Q       e2              . By increasing the term with the negative symbol in the following Equation, the total no-load Q factor (Q₀) is set in the negative region.       
 With the above-mentioned arrangement, the NF can be reduced and the pertinent apparatus can be compacted to allow a practical active-type BPF to be obtained.

Abstract: There is proposed a process for recovering lead, comprising the steps of: feeding molten caustic soda, lead-containing feed and an oxygen-containing gas into a reaction zone having a temperature of 600 to 700°C, as a result of which there are obtained lead metal withdrawn from the process and a melt containing sodium sulphate, zinc and copper sulphides, and gangue. The melt is discharged from the reaction zone and subjected to a first leaching operation to obtain, as a result, a slurry representing a mixture of solid particles of sodium sulphate, zinc and copper sulphides, gangue and an aqueous solution containing essentially caustic soda. Further on, the slurry is filtered to produce a concentrated aqueous solution containing essentially caustic soda and a solid residue. The concentrated caustic soda solution is subjected to thickening by evaporation and the resulting caustic soda melt is fed into the reaction zone. The solid residue is subjected to a second leaching operation to obtain a suspension which is filtered to ultimately produce a cake representing solid particles of zinc and lead sulphides, and gangue having, adsorbed on their surface, a sodium sulphate solution, and an aqueous solution containing essentially sodium sulphate. Said solution is subjected to electrochemical treatment to obtain sulphuric acid withdrawn from the process, and alkali which is fed to said first leaching operation. The cake is washed to obtain a sodium sulphate solution which is fed to said second leaching operation.

Abstract: The present invention relates to rechargeable batteries which include cell casing components (11, 12) enclosing positive and negative plates, separator material and acid electrolyte. The battery includes a plurality of support members (65) extending from one or the other of the casing components, or from both casing components, the support members passing through the plates to permit uniform compression of the internal components. In its preferred embodiment, the battery includes one or more intermediate cell partitions (40) which permit stacking of individual cells to increase voltage. The partition (40) continues the utilization of the support members. In another disclosed embodiment, the electrode plates contained within any particular cell are punched to permit the support members (65) to pass therethrough, with hole sizing selected so that a small hole (105) will remain at each support location, while also insuring that for each support member, only one of the positive and negative plates will touch it, but not both. Shorting along the support member is thereby prevented.
