1474802 Lead-acid battery GOULD Inc 8 July 1974 [9 July 1973 (2)] 30217/74 Heading H1B Crystal growth between the formed negative and positive plates of a dry-charged lead-acid battery which may occur before activation of the battery by the addition of electolyte thereto, is prevented by treating the plates with a metal sulphate soluble in sulphuric acid or water. The preferred sulphate is of sodi...

A process for producing ethanol which comprises reacting methanol, carbon monoxide and hydrogen, characterized in that the reaction is carried out in the presence of (a) a solvent selected from the group consisting of hydrocarbons, and ethers and (b) a catalyst comprising a cobalt compound, a ruthenium compound and a tertiary phosphine in the absence of iodine, bromine, an iodine compound or a bro...

PURPOSE:To decrease the temperature of the outlet waste gas in a waste heat collection boiler and improve the efficiency of the boiler by performing evaporation by the heat exchange with combustion gas between a gas turbine combustor and a gas turbine.

PURPOSE:To enable the shift mode in automatic gear-shift to be set in some kinds of variety and to be changed freely by selecting the desired shift mode.

PURPOSE:In the high stage automatic gear shift controlling apparatus, the speed stage selected according to each range select stage can be changed easily.

In order to correct non-linearities inherently existing in the relation between the value of a hydraulic fluid parameter controlled by a proportional valve and an operating signal controlling the valve, in an arrangement in which the setting of the valve is controlled by effecting a comparison between the operating signal and a feedback signal representing the valve movement, a memory is provided ...

A data communication network having a plurality of nodes interconnected with a communication link, wherein each node shares given ones of its data sets in common with other nodes in the network, and each node is operative to update any shared data set, except if one of the other nodes is also seeking to update the same data set, in which case the node having the higher priority prevails. Each node...

PURPOSE:To obtain desired laser beams instantaneously, and to lengthen life by previously supplying the currents of the irreducible minimum of a demand for lighting an excitation lamp and controlling large currents applied to the excitation lamp in response to the opening and closing of a shutter as necessary. CONSTITUTION:When a laser power supply 1 is turned ON, a power supply circuit 19, a chan...

PURPOSE:To detect malfunction with a simple device, by comparing the output of a plurality of monitor buffers if it is mutually in agreement and discriminating it with a buffer control set when disagreement is detected if the result of comparison is effective. CONSTITUTION:Data required for the processing of instruction is stored in instruction data buffers 3 of a plurality of sets, and when the p...

Reaction injection molded polyurethane elastomers reinforced with inert fillers are made by reacting two streams with one another, one stream containing polyisocyanate and the other stream containing at least one active hydrogen-containing material, wherein all the inert filler is placed in the isocyanate-containing stream before mixing and reaction with the active hydrogen-containing stream. The ...

A safety ski binding, having a jaw-iron which is movable relative to the ski for holding the boot, the jaw-iron being held in a centred position by an elastic device in order to allow release of the boot upon the occurrence of a particular torsional loading acting on the skier's leg, and having a compensation system with a sensor member which is in contact with the boot and interacts directly or i...

A shrinkable polyamide film useful for wrapping hams, sausages, etc. The shrinkable film has a hydrothermal shrinking ratio of at least 30% in both MD and TD and a hydrothermal shrinkage stress of from 300 to 700 g/mm2. The film is produced by a process which comprises biaxially stretching a substantially amorphous film composed of a copolymer of 6,6-nylon/6-nylon in a weight ratio of from 5/95 to...

A low less composite spider arrangement for use in inductive electrical equipment and an air core reactor incorporating the same in which a non-conductive or a conductive material having very low relative permeability and relatively high resistivity is used to fulfill the mechanical and structural requirements of the spider (3), and a relatively small amount of electrical conducting material, bond...

A particular class of sulfolanyloxyalkyl-polyalkylsiloxanes are provided which consists essentially of: (1) monofunctional siloxy units (M DEG ) the respective silicon atoms of which have two alkyls bonded thereto, the third silicon-bonded organic group being alkyl or sulfolanyloxyalky; (2) an average of from about 0.5 to about 10 moles of difunctional dialkylsiloxy units for every two moles of M ...

Readily water soluble polyacrylic acid salt granules are prepared by a process in which a water-soluble powder of a polyacrylic acid salt is granulated by a fluidized bed granulation method while an aqueous solution of the polyacrylic acid salt of a viscosity of 50-700 c.p.s. is sprayed thereon.

In a vehicle disc brake a pair of friction pad assemblies are adapted to be applied simultaneously to the respective inboard and outboard faces of each of a pair of relatively fixed, axially spaced, rotatable discs by an actuator assembly. The actuator assembly comprises a pair of first and second rigid clamp assemblies which are relatively movable axially, and an actuator acting between the two c...
