Abstract: Abstract of the Disclosure Continuously revolving percussion drilling machine, which comprises a body and a drill shank mounted rotatably and axially slidably in the body for causing impacts on the drill rod.  An impact mechanism is positioned in the body for causing axial impacts on the drill shank.  A rotating device is provided for rotating the drill shank around its axis.  The drill shank is provided with a toothing which is coupled in direct engagement with a toothing revolving in relation to the drill shank and rotating the drill shank. The toothing of the drill shank is axially displaceable in relation to the rotating toothing, so that the contact surfaces of the teeth of the toothing on the drill shank and of the toothing rotating the drill shank revolve and are exchanged constantly and teeth operate as cold and well lubricated.  The rotating toothing may be a cogwheel or a tooth rim.

Abstract: Abstract of the Invention A fluid fuse is quickly operable to shut off fluid flow upon rupture or other failure of fluid conducting line or other structural member downstream of the fuse.          The fuse is actuated during decompression fluid flow resulting from decompression of fluid and elastic contraction of structural components downstream of the fluid fuse.  During decompression fluid flow, a valve member is moved from an open position to a closed position by two forces generated by a pressure differential caused by sudden decompression of the fluid and developed across two variable, sharp edge, viscosity insensitive orifices, positioned in series and separated by a flow cut-off and sealing surface.  The closing force, generated by the pressure differential of the upstream orifice is dominant and increases with the displacement of the closing member in a predeterined manner, permitting the use of a high preload and high rate opposing spring, at relatively low pressure differentials.  The sealing surface of the fuse is provided with limited freedom of alignment to permit tight sealing.  The fuse assembly includes a manually adjustable bypass arrangement and a pressure peak attenuating control.

Abstract: ABSTRACT The present invention provides maleated aminophenoxysiloxane derivatives which contain both siloxane and maleimide or maleamic acid moieties.  The compounds have the formula:                                           (I),   wherein R is independently selected from the group consisting of hydrogen, alkyl of 1 to 3 carbon atoms and phenyl; R' is      ,           ,     or         and n = 1 to 6.  Where n=l it is understood that the compound is a 'silane' rather than a siloxane.  Maleated aminophenoxysiloxanes are prepared by reacting diaminodiphenoxysiloxanes with maleic anhydride.  In addition, the resultant maleamic acid derivatives may be cyclized yielding isomaleimide or maleimide siloxane derivatives.  The products are useful as cross linking agents in adhesive applications.

Abstract: WAFER TRANSFER APPARATUS                         Abstract An automated  system  lifts a  batch  of  semiconductor wafers  from a slotted carrier,  transfers them laterally and lowers them into a second slotted carrier.   In doing this, jaws on the lifting apparatus open automatically to receive or release  the  wafers.   With a carrier having relatively high slotted sides, such as the commonly used plastic cassette, a pusher engages the lower edge of the wafers  exposed  through  the  bottom of  the  cassette  and pushes them upwardly sufficiently far to permit the lifter jaws to receive and lift the wafers.   The apparatus is oriented at a slight angle to insure that the wafers are all arranged in precise, spaced, parallel relation so as to cooperate with slots in the lifter jaws and slots in the receiving carrier.   The system has the capability to move two batches of 25 wafers to a quartz boat having 50 more-closely spaced slots, and similarly, two batches from a quartz boat may be transferred to two different plastic cassettes.

Abstract: ABSTRACT Perfluoro-1,3-dioxole is a useful monomer, which polymerizes to either amorphous or liquid homopoly-mers and copolymerizes with tetrafluoroethylene as well as with other monomers to both crystalline and amorphous copolymers having one or more such comonomers incorporated therein.  Amorphous homopolymers and copolymers of perfluoro-1,3-dioxole are useful in such applications as glazing for reactors for hydrogen fluoride reactions. Amorphous homopolymers and amorphous or crystalline copoly-mers form self-supporting films and can be used for coatings and linings which are inert to most chemicals and are stain and weather resistant and as dielectrics for electrical and electronic equipment.  Liquid homopolymers can be used as hydraulic fluids and heat exchange media.  Processes for the manufacture of 4,5-dichloro-2,2,4,5-tetrafluoro-1,3-dioxolane is also disclosed.  The processes comprise either (i) chlorination of ethylene carbonate followed by fluorination with sulfur tetrafluoride and treatment with antimony trifluoride or HF in the presence of anti-mony pentachloride, or (ii) chlorination of 1,3-dioxolane followed by fluorination with antimony trifluoride or HF in the presence of antimony pentachloride.  The resultant 4,5-dichloro-2,2,4,5-tetrafluoro-1,3-dioxolane may be used in the manufacture of perfluoro-1,3-dioxole.

Abstract: Abstract The present invention relates to the discovery of a method by which elemental sulfur may be delivered to a reaction zone, for gas-solids reaction, in the form of a concentrated,  coherent, diffusion-resistant gas thereby permitting  gas-solid  reactions  of  greatly enhanced reaction rates.  It has been found that sulfur, which is first vaporized at approximately 1 atmosphere pressure, and then super heated to at least 1270°F while in transit through a confined space, such as a transfer line, will debouch from said confined space into a reaction zone as a coherent gas which resist diffusion throughout the free space of the reaction zone.  This coherent form of sulfur gas exhibits a dark reddish-violet color.  The coherent form of sulfur gas, since it resists diffusion throughout the  free  space of the  reaction zone,  flows  into concentrated contact with,  and remains concentrated at, the  solids  surface,  thereby producing a gas-solids reaction of greatly enhanced reaction rate.     Utilizing the above discovery a process has been devised by which the sulfur values present in gypsum, particularly waste by-product gypsum produced by the wet process,  may be recovered as SO2 with the concurrent production of lime.

The sandy bark remaining between the knife blade and the drum, however, abrades the knife and the drum. According to the invention, the faces of the drum and of the roll are cleaned by means of water jets.  A perforated pipe in the "throat" between the drum and the support roll sprays the faces clean, so that abrasion is excluded.
