Abstract: ABSTRACT PRODUCING METHYL ETHERS OF BRANCHED MONOOLEFINS     Methanol is reacted with branched monoolefins such as isobutylene, or mixtures of hydrocarbons such as mixed C-4's from or in a refinery, in the presence of methanesulfonic acid.  A column (10) operation is described wherein methanesulfonic acid (11) and methanol (12) are fed in countercurrent fashion to hydrocarbons (13).  Crude product ether is removed as a liquid sidestream (25) above the feed of methanesulfonic acid (11), while hydrocarbons depleted of the reactive branched monoolefins (24) are removed overhead.  The methanesulfonic acid suppresses the vapor pressure of methanol relative to product ether.

Abstract: ABSTRACT OF THE DISCLOSURE         A process for the partial hot dipping of a long steel strip is disclosed which comprises forming an oxidation-inhibiting film, oxygen-impermeable and thermally stable in a hot-dipping bath, which film is produced by the chemical reaction of an iron content in the steel strip with an oxidation inhibiting film-forming agent, such as an inorganic phosphoric acid compound, on a pre-determined area of the steel strip surface, forming, as required, an intermediate layer comprising an inorganic binder, such as water glass, on the resulting film, forming a carbon-containing, plateing-stopping film as a top coat on the intermdiate layer, and hot dipping the steel strip.

Abstract: Lipids in aqueous phase Abstract The present invention relates to a novel advantageous process for the preparation of unilameller liposomes in aqueous phase by converting a suitable lipid component, e.g. phosphatidic acid, into the ionic form by subjecting the lipid dispersion to a change in pH value and subsequently neutralising it. Formation of the unilamellar liposomes is spontaneous, i.e. it takes place without additional external supply of energy. The liposomes obtainable by the process of this invention can be used therapeutically as carriers for drugs of the most widely different kind.

Abstract: Abstract:     For heat-treating rails for achieving a high wear resistance, at least the rail head is, starting from a temperature lying within the austenite range, brought to a temperature at which perlitizing is completed by means of a cooling medium con-taining 20 to 60 % by volume of a polyglycol. This treatment is particularily concerned with  steels  containing 0.65 to 0.85 % C and 0.5 to 2.5 % Mn. A Vickers hardness HV30 between 340 and 380 is obtained.

Abstract: METHOD AND APPARATUS FOR DYNAMIC RANGE CONTROL     ABSTRACT     In apparatus for investigating earth formations traversed by a borehole, improved methods and apparatus are provided for achieving dynamic range control of formation measurements.  In one embodiment adapted to formation resistivity measurements, a well logging tool moving through a borehole emits a current into the adjacent earth formation, and a corresponding measurement voltage correlative to the resistivity is sampled at discrete elevations as the tool traverses the borehole. An average of these voltage measurements is formed.  When the magnitude of this average exceeds or drops below a predetermined range, the magnitude of the survey voltage is decreased or increased respectively by a discrete amount.

Abstract: CURRENT SINK FOR DPT CHANNEL UNIT by Gregor D. McGibbon and Kenneth K. Yu ABSTRACT OF DISCLOSURE           DC saturation effects in the VF transformer of a DPT are re-duced or eliminated with apparatus diverting central office battery loop current away from windings of the transformer when a trunk circuit is seized for an off-hook condition of a calling parties telephone handset.  A physically smaller transformer having increased inductance may then be employed for providing increased return loss at low fre-quencies.  The apparatus comprises a current amplifier that is electri-cally connected across tip and ring lines, with a first switch means in its feedback path, and second switch means for AC coupling a transfor-mer winding to the lines.  When the trunk is idle for an on-hook condi-tion of the handset, the amplifier is disabled and the lines are termi-nated with a large resistance.  When the trunk is seized for an off-hook condition of the handset, binary PF and CF signals cause the cur-rent amplifier to shunt the resistor and to draw a prescribed amount of DC loop current on the lines for energizing a central office A-relay. This also turns on the second switch means for passing VF signals on the lines to and from the transformer, while blocking DC current from the winding, and terminating the lines with a prescribed impedance. When the calling party is dialing, the CF signal opens the feedback path so that the amplifier is turned hard on and off by pulsing of the PF signal for changing the termination impedance and causing resistive pulsing in the central office.

Abstract: ABSTRACT       A packing container for pressurized contents, e.g. beer or carbonated refreshing beverages, can be manufactured from different material combin-ations which together provide the packing container with the necessary strength as well as the required tightness for gas as well as liquid. In accordance with the invention a packing container is formed comprising an outer casing which consists of several material layers and which provides the packing container with its strength and gas-tightness, and a liquid-tight inner container      of flexible plastic material. In the manufacture and filling of the packing con-tainer use is made of the capacity of the contents to give off gas so as to expand the inner contain-er      until it lies closely against the outer shell       and at the same time force the air out of the casing so that the packing container is rendered completely free of air.
