Abstract: Polysiloxane hydrolyzates are neutralized by treating polysiloxane hydrolyzates containing residual acidic constituents with carbon, and then the carbon is removed from the treated neutralized polysiloxane hydrolyzate. Some examples of polysiloxane hydrolyzates that can be treated are hydride functional polysiloxane hydrolyzates and polydiethylsiloxane hydrolyzates. The carbon neutralizing agent especially preferred is carbon derived from bituminous coal. The carbon is removed from the treated neutralized polysiloxane hydrolyzate by passing it through solid liquid separation devices such as plate and frame filter presses, polishing filters, and post filters for removing fines.

Abstract: A process for preparing cyclic organohydrogensiloxanes is disclosed. The process comprises the steps of (A) and (B). Step (A) comprising contacting a silane of the formula RHSiCl2, where R is selected from alkyl radicals having 1 to 12 carbon atoms and aryl radicals, with water to form a hydrolyzate. The hydrolyzate formed in step (A) comprising cyclic organohydrogensiloxanes and linear organohydrogensiloxanes. Step (B) comprising contacting the hydrolyzate formed in (A) with an acidic rearrangement catalyst in the presence of an inert liquid diluent to increase the ratio of the cyclic organohydrogensiloxanes to linear organohydrogensiloxanes in the hydrolyzate. The process further characterized by that the acidic rearrangement catalyst is an organic compound containing a strong acid group which is dissolved in the inert diluent present.

Abstract: A transmission selector is mounted on the floor of an automobile by elastomeric S-shaped straps which permit the selector to move back and forth in a longitudinal direction while holding the selector substantially rigid in vertical and transverse directions.
