Abstract: ABSTRACT OF THE DISCLOSURE           An improved process is provided for preparing polysiloxanes having hydrocarbon radicals bonded to silicon atoms via oxygen, by reac-ting a halosilane with an alcohol and water in the presence of the desired polysiloxane.  The improvement comprises continuously introducing the organopolysiloxane, an alcohol, water and, if necessary, an acid catalyst which promotes the condensation of Si-bonded condensable groups into a reactor equipped with a column, in such an amount that the reactor always contains at least 5 percent by weight of alcohol and 0.001 to 5 percent by weight of catalyst, based on the weight of the alcohol, catalyst and polysiloxane present in the reactor.  The contents of the reactor are heated to, and maintained at, the reflux temperature while the halosilane is introduced into the column at least one meter above the bottom of the column while continuously removing the organopolysiloxane from the reactor at the same rate as it is formed.  This process provides hydrocarbonoxy-containing organopolysiloxanes having a constant, predetermined and con-trolled number of hydrocarbon radicals bonded to the silicon atom via oxygen.

Abstract: Abstract of the Disclosure A liquid filled differential pressure transmitter includes a metallic measurement diaphragm within a pressure chamber and a pair of iso-lation diaphragms sealing the chamber from the process fluid which serve to transmit the applied pressure signals to the measurement diaphragm.  The isolation diaphragms bottom against mating back-up surfaces to limit deflec-tion of the diaphragm during overrange pressure conditions.  An electrically conductive liquid fills the chamber so that measureable electrical resistances are established through the liquid between the measurement diaphragm and a pair of electrodes adjacent thereto formed on opposite walls of the chamber. As the measurement diaphragm deflects in response to applied pressure signals, the electrical resistance between the diaphragm and each of the electrodes changes providing an output signal which is a function of the applied differ-ential pressure.

Abstract: ABSTRACT OF THE DISCLOSURE        It has been discovered that the addition of a small amount (less than 5 percent by weight) of chopped graphite fibers to an electrically conductive silicone elastomeric mixture increases the electrical conductivity to an unexpected degree.          The electrically conductive silicone elastomeric mixture can be coated on a base member and cured to yield an electrically conductive device.        An application of the technology is the manufacture of conductive core for use in automotive ignition cable.  By using this electrically conductive silicone elastomeric mixture, it is no longer necessary that the base member itself be conductive.

The invention relates to a method of and a device for determining a radiation absorption distribution in a part of a body. Per measuring value a contribution of the absorption value in each element of a matrix imagined in the part is calculated. It is demonstrated that this contribution equals the value of the measuring value multiplied by a weighting factor. The weighting factor is a function of the distance between the element and the measuring path along which the measuring value is determined. A calculation method of this kind enables fast on-line calculation of an absorption distribution and the complete reconstruction of the absorption dis-tribution is laid down in a hardware circuit. Complex operations such as F.F.T., convolution and interpolation are not required.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of providing a substrate with a layer of a tertiary compound comprising silicon, silicon carbide and a transition series metal.  In accordance with the method, a substrate having at least a surface layer thereon of a transi-tion series metal is coated with silicon carbide particles having an average particle diameter in the range of up to about two microns.  The coated substrate is then heated in an inert atmosphere to a temperature between 1000 and 1300°C for suffi-cient time to allow diffusion to occur between the silicon carbide and the transition series metal layer, thereby forming the tertiary compound.  Substrates coated with the tertiary compound are particularly suitable for preparation of alkali metal/polysulfide batteries wherein the substrate may be exposed to corrosive attack by molten polysulfide salts.
