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...

A signal from the speed sensor is extracted at a time period which is later than that for detecting a signal from the engine load sensor by a predetermined amount of time. The speed signal thus obtained is used to decide whether or not shifting of the automatic transmission is necessary, so that any incorrect changeover between two or more shift patterns or shifting between two or more of shift po...

The centrifugal separator apparatus includes, in a stationary chamber 1, a rotating system constituted by a treatment rotor 3 having perforated discs 4 which are angularly offset with respect to each other, upstream of a rotary distributor and downstream of a fan. According to the invention, the stationary wall of the chamber 1 delimits longitudinal channels 29 emerging into the intermediate space...

A metering valve which is particularly advantageous for use in gas mixing devices such as patient ventilators, to accurately control the volume and frequency of gas flow for each gas and to provide a feedback of the actual flow through the valve. A valve (82), actuated by solenoid (164) is connected to the core of a linear variable differential transformer (192). As the valve opens, the core (206)...

An apparatus for vulcanizing pneumatic vehicle tires where the tire beads, in the mounted state, are disposed on the radially inner periphery of a rim next to the essentially radially inwardly extending rim flanges. In order to obtain tires having a long service life and tire beads with a good sealing quality, it is proposed that the tire be vulcanized in essentially the proper contour for operati...

A shock wave tube generates a plane shock wave which is divided into two partial waves by means of a splitting device, such as a cone. Adjacent the cone are first and second reflectors. The reflectors have different parabolic curvatures and different distances from the cone. Their respective foci coincide at a common point, where a concrement is located. The partial waves require different transit...

The invention provides a process for preparing a food flavour by inactivating yeast and carrying out enzymatic degradation of biopolymers in conjunction with fermentation with micro-organisms. Preferably the enzymatic degradation is carried out with more than one enzyme either simultaneously or sequentially.

Foamable vinyl chloride polymer composition containing as a foam stabilizer an alkyl acrylate polymer.

of the disclosure: Granular oxymethlene polymers are prepared by cooling a solution or dispersion of an oxymethylene polymer, the temperature of the said solution of dispersion polymer, to a temperature just below the said sintering temperature. As dissolving or dispersing agent there is used a mixture of methanol and water. The cooling of the said solution of dispersion is effected in two stages ...

Some chemical products are so toxic that they must not come into contact with parts of the human body. A package of such a construction that during filling and transport thereof and during the release of product therefrom, the risk of anyone coming into contact with the product is restricted to a minimum, is characterized in that the product is situated in a closed inner container (1) consisting o...

Synthesis gas with an increased hydrogen to carbon monoxide ratio produced from normally gaseous hydrocarbons by the following steps: (a) at least one normally gaseous hydrocarbon is converted into a synthesis gas by partial oxidation with an oxygen-contg. gas; (b) at least one normally gaseous hydrocarbon is converted with steam into a gaseous mixt. of hydrogen and carbon monoxide; (c) the mixt. ...

The subsurface position of a blowing well w.r.t a relief well is determined by detecting acoustic waves emanating from the blowing well at several locations along the axis of the relief well and determining the difference in times of arrival of the waves at the axially spaced locations. The waves are detected at several tangentially spaced locations alongside the borehole wall of the relief well a...
