The control circuit enables the output power of a radio-frequency amplifier (HV) to be kept con...

A compact electrolytic cell with direct through-flow comprises an electrode stack formed as a cartridge unit which is readily exchangeable into and out of a housing which is made of commercially available plastic tubing materials. The cell can be adapted to meet a wide range of application requirements by the variation of parameters such as salt concentration, flow rate, etc.

A multi-stage biological cleaning plant for organically polluted sewage has been designed on modular principles. It consists of two concentric oval basins with the annulus bet between them forming a circulating activated sludge basin. The inner basin has a modular section subdivided into functional spaces for aerobic sludge stabilisation, a partly immersed trickling filter disc and for final settl...

A preamplifier network or circuit for converting non-linear signal information, such as is produced by a mercury cadmium tellurium (MCT) detector, to a substantially linear voltage signal output corresponding to the incident light levels on the MCT detector. Conceptually speaking, the subject preamplifier functions as a constant-voltage variable-current source to the MCT detector, and incorporates...

A valve (10) for dispensing metered doses from a pressurized dispensing container (17) has a valve cup (13) attached to the container. A valve housing (11) fixed to the valve cup has within it nested components (30, 31) the inner one of which defines a metering chamber (16). A valve stem (12) slides through seals (14, 15) one of which is trapped between the valve cup (13) and the inner nested comp...

A machine and method for treating a web (12) by longitudinal compressive action, by pressing web (12) against a driven roll (10) to drive it into a treatment cavity bounded by the roll (10), and an overlying surface (28) of primary member (14), followed by application of retarding forces R by extrusion in which the extrusion orifice bounded by surfaces (26) and (28) is arranged with its axis subst...

Apparatus (21) for dampening a lithographic plate on the plate cylinder (13) of a lithographic printing press (11). The dampening apparatus has a fluid supply roller (22) mounted for rotation on a first axis and rotatably driven at a predetermined but adjustably variable speed. Water is supplied to the fluid supply roller (22) through a plurality of water jets disposed along its length. A metering...

New flight motion concept. It consistsof a decrease of the front pressure of helicoplanes to lower thanthe downstream separation zone pressure. So helicoplanes are pushed forward by atmospheric air instead of being dragged as conventional aircraft are. This decrease of front pressure, according tothe Magnus phenomenon, is effected by adding to the front air flow a rotational velocity. That is done...

The present invention proposes a novel apparatus and method for the manufacture of glass fibers utilizing a bushing confining a body of molten glass over an orifice plate which may or may not have depending tips. Interposed in the glass body is a plate or other device for reducing the pressure of the molten glass body over the orifice plate to a pressure no greater than atmospheric pressure. The o...

Process for the production of synthesis gas and higher hydrocarbons in which a saturated hydrocarbon and an oxygen containing gas having a ratio of hydrocarbon to oxygen of greater than the stoichiometric ratio for complete combustion are introduced into a bed of an inert particulate material. The upward flow rate of the hydrocarbon/oxygen containing gas stream is sufficient to fluidize or to prod...
