PURPOSE:To make the electrolyte immediately reach the surface of the current collector from the surface of the plate by forming a plate layer horizontal to the surface of the current collector and producing cracks in the plate layer. CONSTITUTION:After a slurry mixture composed of lead monoxide, trilead tetraoxide and water is poured into a battery jar 1 to make the mixture expand over the surface...

In the case of a supercharged combustion engine (1), in addition to an exhaust turbocharger comprising compressor (2) and supercharger turbine (3) a further supercharger turbine (3') is provided, the latter being identical to or of a type smaller than the former. The supercharger turbine (3') is integrated with a transmission (8) connected on the input side of the combustion engine (1) and deliver...

Described is a piezoelectric drive element assembly for use in ink jet printer devices. The assembly comprises a piezoelectric drive element, which is characterized by a pair of electrodes spaced apart and thereby electrically isolated from one another on an external lateral face of the drive element. The assembly further includes a printed circuit board having holes through which the drive elemen...

The invention relates to the construction of lamina-sized indents in tread profiles on pneumatic vehicle tyres. In order to reduce the tyre noise emission, the lamina-sized indent is of widened construction at least in the mouth area at the profile surface. In the preferred V-shape of the lamina cross-section, straight or bent indent walls may be present. By increasing the volume, the value of the...

A container forming apparatus for packaging machine by which a vertical tube filled with contents is sealed over a required width at a spacing corresponding to the length of one container and is cut at the midportion of the seal width, the apparatus comprising a slide having forming jaws, and a slide lift assembly drivingly movable by a pulse motor.

Porous electrodes for lead acid storage batteries without supporting plates or grids. The electrodes are porous, self-supporting, structurally integral and electrically continuous. Lead-acid batteries incorporating such electrodes exhibit improved performance characteristics as compared to conventional lead-acid batteries. The electrodes are made by forming a molten mixture of metal (e.g. lead) an...

Novel non-ionic contrast media are efficiently prepared from generally available ionic contrast media or non-iodinated precursors. Particularly, polyhydroxyhalo-hydrocarbons are employed with a triiodo-substituted acylamido benzoic acids in aqueous weakly basic media to selectively substitute the amido nitrogen, followed by activation of the carboxyl group for amide formation.

There is described a blood fractionation system, apparatus and method of processing blood. There is also described a blood fractionation pathway (1 - 15) for use with a centrifugal blood fractionation apparatus (16 - 31) and preferably including a substantially toroidal separation chamber (1).

1414019 Building tyres GOODYEAR TIRE & RUBBER CO 1 June 1973 [28 June 1972] 26341/73 Heading B7C In a tyre building system, preformed endless carcass bands, e.g. of radial, metal cords, and tread and inextensible belt assemblies are transferred in succession from their respective building machines A, C by respective carriers 130, 180 to a radially expansible tyre shaping drum B40 when the latter ...

An operation mode monitor for a microcomputer in which any one of a plurality of operation modes can be selected in response to an operation mode setting signal generated from an external circuit when reset. The monitor according to the present invention can check whether a predetermined correct operation mode has been selected in the microcomputer in accordance with a checking program and output ...

The safety ski binding is primarily intended to retain the toe end of a ski boot and comprises a yoke pivotally mounted on a cross-pin in a stationary hollow body. The jaw unit for retaining the ski boot is guided in longitudinal sliding motion within the yoke. The jaw unit is provided with semi-cylindrical grooves directed towards the ski boot and having the function of cooperating with support r...

Rigid polyurethane foams are described which, in addition to conventional additives, contain from 5 to 75 % by weight based on the total weight, of plastic particles - preferably from recycled material. Rigid foams of this type are particularly suitable for use in the furniture and construction sectors. The present invention furthermore relates to a process for the production of these rigid foams ...
