An improved actuator assembly for an electromagnetically-actuated spring-loaded positioning system in displacement machines, such as for lifting valves in internal combustion engines. The positioning mechanism has a spring system and two electrically-operated, opposed actuating solenoids, by means of which the actuator may be moved between, and held at, two discrete, mutually-opposite operating po...

PURPOSE:To increase initial charge capacity for obtaining battery performance stably even if the battery is preserved for a long time at high-temperature condition by performing initial charge with electric current more than 0.025CA after supplying an amount of electrolytic solution into the battery excessively in comparison with the quantity of the liquid which can be well absorbed in a positive,...

A process for the preparation of 2,3-dimethylbutene-2 is disclosed, which comprises the steps of converting isovaleraldehyde to isopropylacrolein, hydrogenating alpha -isopropylacrolein to form 2,3-dimethylbutanol, dehydrating 2,3-dimethylbutanol to form an olefin mixture comprising 2,3-dimethylbutene-1 and 2,3-dimethylbutene-2, and isomerizing the 2,3-dimethylbutene-1 contained in the mixture in...

The invention relates to a process and apparatus for the controlled preparation of a saturated solution of a solid material in a solvent. The amount of solid material 3 dissolved in the solution prepared is monitored by comparing the volume of solvent flowing into compartment 2 with the volume of solution subsequently flowing out, using volume measuring means 9.

The compressed-air pipe (20) leading to the splicing chamber (1) of the yarn splicing device encloses a humidification tube (30) which opens into this compressed-air pipe and which proceeds from a container filled with liquid (24) in which the liquid level is below the aperture (5) of the splicing chamber (1).

The invention consists of a splicer device to disassemble and recompose yarn mechanically, whereby the splicer device comprises facing disks to untwist and retwist mechanically two yarns positioned between the two disks, a cutter to eliminate excessive tail ends of yarn protruding from the two disks, a crank to set the two disks in rotation, a cam to actuate the cutter that eliminates the excessiv...

The invention relates to new aryloxy phenoxy acyl malonates of the general Formula I (I) a process for the preparation thereof and herbicidal compositions comprising the same. In the general Formula I R1 stands for hydrogen, halogen, trifluoromethyl, trifluoromethoxy or cyano; R2 represents hydrogen, halogen or methyl; R3 is C1-4 alkyl; and the R3 substituents may be the sa...

The dissolution rate of water-soluble polymers in water can be precisely controlled. This is accomplished by inverting a water-in-oil emulsion containing the water-soluble vinyl polymer into water which contains at the time of inversion an exact amount of an emulsifier system having an HLB number which has been predetermined to produce a specific solubility rate for the water-soluble vinyl polymer...

Entangled nonwoven fabrics are dry print bonded to produce nonwoven fabrics having an excellent combination of strength, softness, and durability.

A high temperature and flame resistant closed cell polyimide foam material and methods of making the foam. An aromatic tetracarboxylic acid dianhydride is reacted with an oxomine to produce an N-substituted imide, which is then esterfied with a suitable alcohol. The resulting liquid is dried and the dry residue is reduced to a uniform powder having particles with diameters generally in the 0.5 to ...

Reinforced phenolic laminates are provided with a finishing coat of a butylated phenol-formaldehyde resin, thereby removing surface irregularities. The finishing coat can be mass-pigmented to the desired color, thereby obviating the necessity of any additional color-containing coatings.
