Ethylene glycol is prepared by a process in which ethylene oxide is extracted from an aqueous solution with near-critical or super-critical carbon dioxide. Thereafter an ethylene oxide-carbon dioxide-water mixture is contacted with a catalyst to form ethylene carbonate, which is then hydrolyzed to ethylene glycol in the presence of the same catalyst. The ethylene glycol is separated as product and...

The low temperature stability of an additive product for imparting desirable properties such as water repellency, set-retardation, etc., to hydraulic cement compositions and Portland masonry cements in particular, is improved by the addition of a small amount of certain low molecular weight, water soluble, non-ionic organic materials (e.g. alcohols, ketones, amides, and aldehydes) to the additive ...

PURPOSE:To rationalize the configuration of a brake system by using a dust preventive boot, which is provided to enclose against the outside air an opening formed either in the fixation part to the car body or the callipers and a slide fitting part of the slide pin, and equipping the callipers with a return sliding action. CONSTITUTION:This slide support construction is equipped with an outside...

PURPOSE:To wire a semiconductor device with high reliability by pressurizing an electrode with lead wirings with a thermal energy transmission material and emitting thermal energy via the transmission material to a pressurized part. CONSTITUTION:A chip electrode and lead wirings 11 positioned and superposed are pressurized with a transmission material 12. An infrared ray laser light is emitted via...

A method for heating a riser of a molten refractory material in which after a heat molten refractory material is poured into a mold, a melt of the molten refractory material at an upper portion of the mold is directly subjected to induction heating by conducting an electric current by application of an AC voltage at a frequency of from 50 to 1,000 KHz to an induction coil with at least 2 windings ...

A method of combating ectoparasite (especially acaricide) and helminth infestations in animals, especially sheep and cattle, which comprises treating said animals with an effective amount of a compound of the formula: where (R<1>)m represents up to 4 optional substances, m being 0 or an integer of from 1 to 4, each R<1> independently being C1 C4 alkyl, C1-C4 alkoxy, C1-C4 alkylthio, halo,...

A tablet dispenser comprises at the lower end of its storage container a positioning passage (5), of which the outlet opening can be closed by means of a slider (3). The positioning passage (5) is so dimensioned that there is only sufficient space for tablets to lie upright on their peripheral edge, being only slightly wider than one tablet. A pocket (4) open towards the passage (5) is formed in t...

The present invention relates to flexible containers (1) having at least one lifting loop (10), and a central part and a bottom (2). It also comprises manufacture and application of such containers. During lifting and transport lifting forks can be applied which are placed in or between devices in the container's bottom, and this results in a minimum lifting height which is important during loadin...
