Diesters of the formula wherein R1 and R2 are hydrogen or alkyl of from 1 to about 20 carbon atoms, and X and Y are alkyl, alkenyl or dienyl of from about 12 to about 18 carbon atoms, useful as low calorie synthetic oils suitable for consumption by mammals.

1. A coupling member for transmission of shock waves from a source of shock waves to a patient to be treated, said coupling member being made of an elastic, shape-retaining material (22) with moist outer surfaces (24, 26) and being provided with an insert (38) that increases its mechanical strength, said insert (38) projecting beyond the elastic, shape-retaining material (22) and having grasping m...

In the production of such bodies, moulded bodies produced by paste extrusion are freed by drying, in a first step of a continuous process, from the lubricating or parting agent used in their production and, in a second step, are stretched and the polymer material simultaneously sintered at a temperature at least equal to the crystallite melting temperature of the polymer. Stretching may be effecte...

A process for treating a waste water containing uranium and fluorine comprises a neutralizing precipitation step wherein slaked lime is added to the waste water containing uranium and fluorine and precipitate thus formed in separated and removed, and an adsorption step wherein supernatant from the neutralizing precipitation step is contacted with a chelating resin which can selectively adsorb fluo...

The marker is for a surveillance system defining an interrogation zone. A field generator provides a magnetic filed of variable frequency within the zone. A marker is secured to an article to be taken across the zone. The marker has an elongated ductile strip of magnetostictive ferromagnetic material. The marker resonates mechanically at a frequency within the range of the incident magnetic fi...

A process for the preparation of perhalomethanesulphinic acid salts of general formula (I) [X1 X2 FC - SO2 ]3-n M in which X1 and X2 represent an identical or different halogen atom chosen from F, Cl and Br, M represents an alkali metal or alkaline-earth metal, n is equal to 1 or 2 depending on the valency state of the metal M, characterized in that an alkali metal or alkaline-earth metal dithi...

PURPOSE:To process the renewal of a message during the service, to process automatically the changing-over to a new message to which time limit is designated and to improve the service of a system by storing a preliminary message in a filing device and executing a preliminary message registering processing to set the preliminary pointer of a corresponding item and a preliminary effective time limi...

Mixtures of alkyl glycosides and fatty alcohols are readily separated by distillation without thermal degradation of glycoside. In the presence of one or more viscosity-reducing agents which are heat-stable and color-stable at temperatures of up to 160 DEG C., which are miscible with the alkyl glycosides, which have a boiling point at 760 mbar at least 50 DEG C. above the boiling point of the fa...

The N-glycosylamide derivatives have the general formula (I) in which R<1>, R<2>, R<3>, R<4>, R<5> and R<6> have the meaning given in the description.

PURPOSE:To improve ability for purifing unburnt alcohol by providing a bypass passage on an exhaust gas passage located between a catalytic converter and a muffler placed downstream from said converter, and fitting an unburnt alcohol trap into said passage. CONSTITUTION:A bypass passage 15 is provided between an exhaust gas passage 14, where a catalytic converter 13 is mounted for purifing exhaust...

A tubular conduit formed of resilient, flexible, thermoplastic material having an intermediate portion with at least one enlarged section that has a flow passage of substantially greater cross-sectional area, and a wall portion of lesser thickness and lower resistance to deformation, than found in the remainder of the conduit. The method of making the collapsible conduit, involving the steps of re...
