An electrical socket connector is comprised of three principal parts (1, 35, 53) of which the first two are contoured internally to receive electrical socket contacts and connecting conductors. The first and second parts have interlocking surfaces (24, 41) at one end which when engaged hold those ends together and also have apertures at the other end to receive a third part (53) of U shaped form t...

Two part silicone casting compositions for dentistry are colour coded for different classes of viscosity; for example, by dyeing the base paste a colour assigned to the respective class of viscosity and filling part of the catalyst paste dispenser (1) with a paste of the same colour (J), the remainder (K) being undyed or of a contrasting colour. The illustrated arrangement will produce a catalyst ...

A substantially flat collapsed plastic bag with an evacuation form unit insert positioned therein as manufactured to serve as a form about which the filled bag will collapse as it is emptied. The form unit comprises a ring for mounting the unit on the spout of the bag and a multi-channel form extending radially from the ring and hingedly connected thereto. A simple method is provided for manufactu...

Flame-retarding sealing compounds based on hydraulic binders are described which are characterized by a content of dehydratable fillers and melamines.

A liquid phase oxidation reaction is carried out by with-drawing a stream aqueous reaction medium from a tank 2, heating it e.g. in heat exchanger 24 an then returning it to the tank 2. Once a chosen reaction temperature is attached oxygen is added to the stream in a venturi 18 and the heating is discontinued. The stream containing fine bubbles of oxygen is re-introduced into the tank through nozz...

A modified activated sludge system is provided wherein wastewater containing BOD5 and phosphate values is admixed in an initial zone with biomass-containing recycled sludge to form a mixed liquor under conditions effecting sorption of BOD5 in the biomass. Subsequently, said mixed liquor is subjected to aeration in an oxidation zone under conditions for effecting oxidation of BOD5, such that oxidiz...

PURPOSE:To make stable machining attainable in preventing a wire from breaking as well as to aim at improvements in machining efficiency ever so better, by detecting a discharging state lying between a wire electrode and a work, while controlling a brake to make for a direction where its tension is weakened in time of discriminating trouble states in an electric arc and a short circuit. CONSTITUTI...

PURPOSE:To enable an image to be formed only by peeling a photosensitive film by laminating on a support a metal compd. layer, its surface treating layer, and a photosensitive layer increasable in adhesion to the surface treating layer by exposure in succession. CONSTITUTION:The layer of a metal compd., such as SnO2, In2O3, TiO2, ZnO, or CuI, is formed on a support made of ceramics or film forming...

PURPOSE:To realize a bus line driving circuit with a small chip area, by providing a p-channel MOS transistor (Tr) for pre-charging to a bus line and performing the output to the bus line by means of an n-channel MOSTr only. CONSTITUTION:During the ''1'' level period of a timing signal T1, a p-channel MOSTrTPR is turned on and a bus line 1 is pre-charged. Thereafter, if an output signal from a cir...

High BOD clarified wastewater is treated in a contactor with activated sludge for rapid BOD absorption without appreciable metabolism of the BOD. Shortly thereafter the sludge is separated from the effluent of reduced BOD. The sludge is aerated to restore its BOD absorption capacity and recycled to the contactor for treatment of incoming wastewater.
