Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to structural combinations and to the connecting elements therefore, particularly for prefabricated reinforced concrete assembly construction.  In the past, the solutions proposed to the problem of attaining joints stiff in bending by means of point-shape supports of elements resting on frusto-conical abutments, have proved unfavourable since the magnitude of the clamping force attained thereby is very low.  It is an object of the present invention to provide a combination of structural elements for prefabricated unit construction and also in normal construction wherein the structural elements of a building, because of the shape of their abutment or joint region, establishes a simple, detachable, push-and-pull resistant joint which is also stiff in bending. The solution of this problem is based on the fact that a curved surface can also be formed in shape and positioned that its slope at any point, corresponds to one of the two principle tension directions standing at right angles to each other.

Abstract: ABSTRACT         A filter apparatus for pressurized material in flowable form, such as molten synthetic resin, in which an elongated filter web which moves into and out of a filter chamber through respective sections of sealing channel has a plurality of seal members of thickness greater than the thick-ness of the filter web, sized for internal sealing engagement with imperforate walls of the channel sections.  The lengths of the channel sections are greater than the spacing between successive seal members, ensuring throughout operation that at least one seal member is located in each channel section to seal the filter chamber from external space, while enabling the filter web to be stabilized.  Preferred forms of the seal members enable the filter web to be effectively supported by a support member while in filtering position, and enable the pressure of the fluid being filtered to assist in the sealing action.

Abstract: Abstract of the Disclosure A patty machine for forming successive patties of a predetermined size from a quantity of bulk product, such as ground meat.  The machine includes a charging chamber in which the product is pressure-fed into a patty mold cavity by means of  intermeshing, positive displacement, self-wiping compressor screws.  The product is delivered from a feed hopper to the entrance of the charging chamber by means of intemeshing, self-wiping conveyor screws which operate on a demand basis to convey  the product to the compressor screws only as needed to thereby avoid unnecessary working or kneading of the product.  Shafts for driving and supporting the conveyor and compressor screws extend throughout the length of the machine and each carries one conveyor and one compressor screw.  The compressor screws are keyed positively to their respective shafts while only one conveyer screw need be so keyed, the unkeyed conveyor screw or screws being driven through intemeshing relationship with the keyed conveyor screw.  By virtue of the self-wiping characteristics of both the conveyor and compressor screws, fat accumulation along the screws, which are often a problem in working with ground meat and similar products, are prevented, thereby avoiding the problem of fatty accumulations breaking off as large clots and being charged into the patty mold.

Abstract: DIGITAL TIMING RECOVERY            Abstract of the Disclosure Sample timing recovery in a differentially coherent phase-shift keyed data transmission system is accomplished through the use of digital techniques.  Samples of received phase-modulated signal waves taken at a rate high with respect to the carrier frequency are applied to a delay medium advantageously implemented by a shift register.          Stored samples spaced by known carrier phase differences are compared for the purpose of detecting phase changes. Digital indications of such phase changes resulting from differentiation of comparator outputs are then effective to control a phase-locked oscillator and provide a substantially jitter-free timing recovery wave without using excess bandwidth for the transmitted wave.

Abstract: ABSTRACT Data processing equipment suitable for recording details of manually connected telephone calls has a plurality of operator stations with keyboards and VDU's connected in groups to operator's control units which respond to keyed instructions to obtain data from peripheral units storing such data and for recording on magnetic tape cartridge the details of the calls. Each operator's control unit is connected to eight operator stations but is capable of handling inputs from twelve such stations.  In the event of breakdown of an operator's control units the eight stations allocated to it are divided into two groups of four which are transferred to the two control units adjacent to that which has broken down.  Among the criteria used to determine whether a control unit has broken down are the filling of buffer stores and the failure to perform a particular operation within a predetermined interval of time following the previous performance of that operation.

Abstract: ABSTRACT OF THE DISCLOSURE     A continuous, essentially closed recirculating papermaking process is provided by using a dispersing me-dium of adjustable viscosity.  The process permits the continuous reuse of the medium under preferred operating conditions.  It includes the steps of forming a dispersion of fibers within the adjustable medium containing  a  pH sensitive viscosity producing agent, reducing the fiber consistency and the viscosity within the dispersion while maintaining the concentration of the agent substantially unchanged, subsequently forming a fibrous web material on a papermaking screen from said dispersion of reduced fiber consistency while separating the dispersing media from the fibers forming the web and continuously collecting the sep-arated media and recirculating it within the system to ef-fect a subsequent fiber dispersion as well as a fiber con-sistency reduction and viscosity reduction without substan-tially changing the concentration of the viscosity producing agent.  The separated and recirculated dispersing media is capable of forming a high viscosity dispersing media for the fibers at the time of forming the subsequent fiber disper-sion without the addition of more viscosity producing agent.
