Abstract: 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.

Abstract: A process for the chlorodephenylation of a phenyl-containing disilane to produce alkylhalodisilanes is described. The process comprises (A) adding an aluminum halide, AlX.sub.3, to a phenyl-containing disilane, having the formula,R.sub.3-a (C.sub.6 H.sub.5).sub.a SiSiR.sub.3-b (C.sub.6 H.sub.5).sub.b,wherein the phenyl-containing disilane has a melting point lower than about 50.degree. C.; and the aluminum halide is added to a concentration greater than about 1 mole percent relative to the phenyl-containing disilane; (B) contacting the phenyl-containing disilane and the aluminum halide, in the absence of a solvent, with excess anhydrous hydrogen halide gas at a temperature less than about 50.degree. C.; (C) facilitating conversion of the phenyl-containing disilane to the alkylhalodisilane; and (D) isolating and recovering the alkylhalodisilane.

Abstract: A process for the preparation of silyl ketene acetals of the formulae,R.sup.1 R.sup.2 C=C(OR.sup.3)OSiR.sub.3.sup.4 and R.sup.1 R.sup.2 C=C[OSiR.sub.3.sup.4 ].sub.2,from the reaction of a malonate compound with a triorganohalosilane in the presence of an alkali metal. The malonate compounds are dialkyl dialkylmalonates, bis(trialkylsilyl) dialkylmalonates, and dialkylmalonic acids. The triorganohalosilane is present in stoichiometric excess relative to the malonate compounds. Silyl ketene acetals are isolated and separated.

Abstract: 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.
