Abstract: A diode-containing connector which is improved in its overcurrent resistant characteristics with its increased heat capacity and its improved heat radiating property around a diode therein. The connector comprises terminals mounted in a juxtaposed relationship and one of them is attached with a diode element securely fixed to a base end thereof. A connecting plate electrically interconnects the diode element and a base end of the other terminals. The base end of the diode-attached terminal is bent to form a folded section having an increased thickness while the connecting plate has a thickness equal to or greater than 1.0 mm in order to ensure sufficient heat capacity and heat radiation from the connector.

Abstract: Gasoline capable of further processing into diesel fuel is produced by catalytic conversion of lower olefins, using a zeolite catalyst which has been modified by substituting a significant portion of the cation sites thereof by basic cations. A preferred catalyst comprises a zeolite and a binder, said catalyst containing at least 0.2% by weight of exchangeable basic cations. The gasoline so produced is readily converted by contact with a Friedel Crafts catalyst into a hydrocarbon product having a significant fraction boiling in the distillate range.

Abstract: The walking beam of a pumping unit is suspended from an oscillating hanger arm. It is pivoted at one end to a crank and to a link, the other end of the latter being pivoted to a fixed position shaft. At the other end of the walking beam is a point which follows a virtually rectilinear path between a bottom dead center position and a top dead center position. This point may therefore be coupled through a rigid member to an oil well pump sucker rod line.

Abstract: An electrolyte containing 65 g/l zinc and 150 g/l Cu is purified in zinc, that is, the copper is removed, by causing the electrolyte to fluidize a bed 8 of 1/2 mm copper particles. The bed is fluidized by 25% to make it 42 cm deep. An anode 11 is disposed above the top of the bed. A cathode 9 is disposed part-way up the bed. Copper is electroplated onto the bed particles. Any zinc which may be electroplated onto the bed particles tends to redissolve with concomitant cementation, on the particles, of copper, which can be recovered. The electrolyte is thus eventually completely stripped of copper and can be used for zinc electrowinning.By controlling the pH of the electrolyte, substantially one metal, or one desired combination of metals, may be removed. In particular, pure copper deposition can be completed at low pH even in the presence of cadmium; upon a substantial increase in pH, cadmium deposition will occur.
