摘要： A polycarbonate process comprising contacting in the presence of a base, a .beta.-fluoroaliphatic carbonate, and a polyhydroxy compound selected from alcohols and/or phenols. The resulting polycarbonates are useful as polycarbonates per se, or useful in the preparation of high molecular weight polycarbonates which can be molded or formed into films, laminates or reinforced plastics by conventional techniques.

摘要： A therapeutic radiographic apparatus includes a source of a pencil-like beam of penetrating radiation which requires to be positioned relative to a patient's body so that the radiation passes, at all times during therapy, through an anomaly, such as a tumor, in the patient's body. It is difficult to maintain coincidence of the beam with the anomaly, and this invention provides means for indicating optically a point of contact of the beam with the patient's body. The point of contact may, for example, be the point of emergence of the beam from the body.

摘要： The resiliently coated metallic finger seal described herein is formed of two metallic seal members being fixed together at one end with fingers projecting rearwardly therefrom. The fingers on each member are offset so that the slits of each metallic seal member are not aligned. The fingers of the two members are then encapsulated by a resilient coating material, such as a room temperature vulcanizing silicone rubber. The seal means is described as annular and can be constructed of one piece or a plurality of sections. In constructing the seal means the metallic seal members are cleaned, primed where it is desired to have the resilient coat permanently affixed, and the resilient coat is then applied. The resilient coat does not cover the entire fingers so that the proper flexibility at the hinge location will remain. After curing of the resilient coating material a heat reflecting and lubricating material is placed thereon.

摘要： A solid source consisting essentially of high purity aluminum metaphosphate, Al(PO.sub.3).sub.3 is used for introducing elemental phosphorus into P-type silicon chips or wafers of semi-conductor grade. The aluminum metaphosphate functions as a source for the controlled release of P.sub.2 O.sub.5 vapors which are directed to the desired face of the silicon wafer. The reverse side of the silicon wafer receives little or no phosphorus and consequently retains its character as P-type silicon.

摘要： Dehydroformylation of isomeric acetoxybutyraldehydes, with minimal dehydroacetoxylation, can be accomplished at a temperature in the range of 120.degree.-250.degree. C. in a nonoxidizing atmosphere in the presence of an essentially neutral noble metal catalyst to produce allyl acetate, 1-propenyl acetate or mixtures thereof. This reaction permits recycle of the undesired isomeric acetoxybutyraldehyde products of the hydroformylation of allyl acetate of 1-propenyl acetate to the desired 4-acetoxybutyraldehyde which is an intermediate in the production of 1,4-butanediol useful in making polyesters.
