Abstract: ABSTRACT OF THE DISCLOSURE         A method of changing a felt in the press section of a paper machine.  The normal run of the felt passes through a space under the floor of the paper machine hall.  In the press section its lower roll is rotatably supported by one or several cantilevered beams.  In the method, frame inserts carrying one end of the canti-levered beam are first removed and then a lifting arrangement supported by the cantilivered beam is used to lift the guide rolls lying within the loop of the felt and located in the under floor space, into an upper position adjacent the cantilevered beam.     The loop of the new felt is then spread out to the configuration required by the rolls coming to lie therewithin.  The felt loop is then pushed in, using special equipment so that it passes over the rolls lying inside the loop and around the cantilivered beam through the space vacated by the removed inserts.  The rolls which have been raised into the upper position are then lowered into their normal operating position in the underside space, whereupon the frame inserts are replaced.

Abstract: ABSTRACT     There is disclosed an improved reverse osmosis membrane which is particularly useful in water purification.  This membrane includes a thin, active layer of a relatively inert, film forming, polymer, which is capable of dissolving a limited amount of water.  The active layer is used in association with a porous support.  This active layer is disposed on a hydrogen layer which serves to facilitate the movement of water away from the active layer generally to-ward the pores in the support.  The support used is an asymmetric layer or membrane in which the porosity increases with the distance from the hydrogen layer.  The complete membrane may be made by employing solvent solutions which are successively applied to the support layer or membrane and from which the solvent is removed.  The film forming polymer may be selected from the group consisting of hydro-philic, partially hydrolyzed polyvinyl ester, epoxy and phenolic polymers.  An active layer of cellulose triacetate in association with a porous polyvinylidene fluoride is exemplary of a reverse osmosis membrane.

Abstract: ABSTRACT                   BUILDING COMPONENTS         The invention relates to building components (10), for example studs for supporting wall boards, made of a plaster-resin mixture, with a fibrous sheet (13) embedded near the surface.          Such components can also be used, for example, as ceiling panels or acoustic tiles, for which purposes they may be of hollow or channel form, and be filled with fibrous or other porous material.    Components according to the invention have excellent fire-resistant properties.  Such components can be made by, for example, introducing a plaster-resin slurry into a mould lined with fibrous sheets, and allowing the slurry to set, or they may be made continuously by, for example, passing the slurry and sheets through one or more suitably profiled conveyors, vibration being employed to cause the slurry to penetrate through the sheets.

Abstract: ABSTRACT            METHOD OF WRAPPING TAPE AROUND A PIPE          A method and apparatus for providing a substan-tially void-free tape wrapping around a pipe 1 having a longitudinal weld bead II protruding from the surface thereof.  While the pipe 1 is simultaneously advanced and rotated, liquid viscous sealing material is applied to the pipe, and the applied sealing material is then doctored by means of at least one doctor blade in doctoring station 5. The doctor blade faces the advancing pipe surface, with the axis of the doctor blade at an angle of about 10° to 50° to the axis of the pipe 1, and is urged against the pipe 1 so that it is resiliently deformed by the pipe 1 and accommodates passage of the weld bead 11 underneath it.  In this way the doctor blade doctors the sealing material so that it provides a smooth transition between the weld bead 11 and the adjacent pipe surfaces.  The tape 61 is then spirally wrapped around the pipe 1.  The invention is particularly useful when a heated sealing material, eg. a hot melt adhesive, is applied to a heated pipe which is subsequently wrapped with a heated polymeric tape having the same sealing material on its interior surface.

Abstract: IMPROVED PROCESSOR MODULE FOR A PROGRAMMABLE CONTROLLER     Abstract of the Disclosure A processor module is one of several modules mounted in a rack to form a programmable controller.  The module has a microprocessor that executes a sequence of machine language instructions to interpret and thereby execute macroinstruc-tions that are part of a control program stored in a read/write volatile main memory.  The rate of execution is improved by reducing the instructions in a fetch sequence used in coupling each macroinstruction to its interpreter sequence of machine language instructions.  Hardware assistance is provided to allow expansion of macroinstruction operation codes as they are fetched.  The processor module also allows the user to program his own interpreter sequences for specially defined macroinstructions and to load these sequences into a nonvolatile memory that is plugged into the module.  An external auxiliary power supply is connected to the processor module to supply the programming voltage required by the nonvolatile memory.

Abstract: ABSTRACT OF THE DISCLOSURE     There is disclosed herein an antenna, particularly for use at high frequencies such as approximately one gigahertz and above, which is frequency selective.  The antenna design allows signals at a given frequency to be pre-ferentially received, as distinguished from broadband reception.  The antenna design can be modified for reception of signals of different given frequen-cies.  The antenna comprises several parabolic sections in the form of con-centric rings or segments with each segment being offset axially from the next adjoining segment to thereby provide an antenna which is relatively flat, or having a low profile, as compared to a standard parabolic antenna.     The surface of each segment is a segment of a different focal length para-bola, but with each parabolic surface being a function of the signal wavelength (or frequency) to be received by the antenna.  The antenna may be round, rectangular or have other shapes.  Also disclosed are feed and pick-up arrangements for the antenna.  In addition to the frequency selective characteristic of the antenna it can be made from various materials and is relatively simple to manufacture, and its low profile minimizes wind loading and mounting problems, and the like.
