A process of curing and cross-linking methylhydrosiloxanes by contacting and forming a mixture of an allyl amide with at least one methylhydrosiloxane in the presence of a Group VIII metal catalyst, and heating the mixture of the allyl amide, the methylhydrosiloxane, and the Group VIII metal catalyst, in the presence of ambient moisture until the methylhydrosiloxane becomes cured and cross-linked.

Process to produce silyl ketene acetals

A surgical drape support device for use with a cover sheet and a conduit for supplying oxygen to a patient disposed on a surgical operating table. The device has a base member which is inserted between a mattress and the surgical table and a support rod which has a drape arm for disposition over a patient. The drape arm can also function as an oxygen distribution means. The base member and the support rod are interconnected by a unitary adjustment means which provides for at least four degrees of adjustment motion for the drape support arm. All adjustments to control the positioning of the drape arm are made from a location removed from the operating field and the patient and are made without removing the overlying drape which is used to retain an oxygen atmosphere over the patient's nose and mouth. One of the degrees of adjustment motion is over an arc about a longitudinal axis which is located parallel to and closely spaced from the edge of the operating table in order to allow movements of the patient's head to be followed.
