Abstract: METHOD AND APPARATUS FOR PROVIDING THE INNER SURFACE OF A PIPE WITH A FLEXIBLE TUBULAR LINING MATERIAL            Abstract of the Disclosure A method and an apparatus for providing the inner surface of a pipe with a flexible tubular lining material by means of liquid resin under pressure comprises fixing one end of such material so that it is turned inside out at the fixed end.  Fluid pressure is then applied from the rear of the assembly to push the lining material forward within the pipe while effecting evagination of the lining material to attach the inner surface of the lining material exposed by evagination under pressure tightly to the inner surface of the pipe.  The invention is characterized by previously forming a reservoir of the liquid resin enclosed in the interior of the unevaginated portion of the lining material positioned in the rear of the fixed portion.  The lining material is passed through the reservoir to apply the resin to its inner surface.  The lining material is squeezed externally to adjust the quantity of the resin applied to this inner surface.  The liquid resin-applied inner surface of the lining material is then applied to the inner surface of the pipe under pressure to form a flexible tight lining.  This method is advantageously utilized for preventing leakage of various kinds of gas and liquid from pipes.

Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus for producing a tubular centerfilled food product having a rigid, friable baked outer shell and a core of edible filling material by a continuous, straight-through process.  A semi-liquid batter having a relatively high sugar content is carried between a pair of spaced apart heated moving surfaces and baked to form a continuous, elongated flat thermo-plastic sheet having a controlled thickness.  The continuous thermoplastic sheet is rolled around its longitudinal axis while warm and pliable to form a continuous tube having a closed longitudinal, non-overlapping seam.  As the baked sheet is rolled around its longitudinal axis, a viscous  edible filling material is injected into the core of the continuous tube as it is formed.  The filled tube is cooled until the outer shell becomes rigid and is then cut into pieces of a desired length.

Abstract: ABSTRACT OF THE DISCLOSURE          This disclosure relates to a method of manu-facturing a pneumatic tire having a cast body of visco-elastic material, a road-engaging tread surface and a girdle member of reinforcing cords located in the crown area of the cast body.  The method comprises the steps of assembling an annular hoop assembly with the girdle member (having a predetermined radius of curvature, its reinforcing cords at the exact cord centerline diameter desired in the finished tire, and a predetermined tension on the cords) located on the inner periphery of the hoop assembly and a spacing support member located on the outer periphery of the hoop assembly; inverting or turning the hoop assembly inside out thereby locating the girdle member on the outer periphery (without changing its cord diameter, its radius of curvature and its cord tension) and the spacing support member on the inner periphery; mounting the inverted hoop assembly on the annular core of a tire mold so that the girdle member has its reinforcing cords at the exact cord centerline diameter desired; closing the tire mold; filling it with a viscoelastic material and curing the material.  The method of this invention may be used to manufacture a tire with a tread  of viscoelastic material or of conventional, carbon black reinforced, rubber.  In the method of this invention wherein a conventional rubber tread is used, an additional step is necessary wherein the precured conventional tread is placed in the tread section of the mold prior to the injection of the viscoelastic material.

Abstract: A B S T R A C T                  ALARM MONITORING ARRANGEMENTS F12311/A3404       FOR DIGITAL TELECOMMS.           P.V. Creteau SWITCHING NETWORKS            In digital telecommunication switching systems the switch block includes an alarm monitor unit (AMU) which is used for initiating maintenance related commands in addition to monitoring, persistance checking and filtering alarm outputs.  It is particularly useful in relieving the main processing system of routine alarm processing.  The AMU collects line and switch block fault indicators from the digital line termination units DLT, applies persistance checks to determine if the alarm is transient or significant and depending on the outcome it identifies the precise location of the alarm and formats an error report to the processor.  Each DLT communicates to and from an AMU by way of an alarm interface unit in the time switch serving the DLT using status and command highways respectively over 2048 kb/s balanced lines.  The DLT uses 32 time slots to code-up status information in a time related manner (i.e. bit n of 256 has a defined significance such as speech parity error plane 1, channel m).  The particular inventive concept is embodied in the arrange-ment where bit 6 of all channels is a "flag" per DLT, indicating that the DLT has some error, alarm or other information, to convey to the AMU.  The AMU can select status information from 1 of 32 DLTs but in parallel with the reception of such data the AMU continues to receive the bit 6 flag of all 32 DLTs, one DLT flag per channel period.  Persistance logic in the AMU on the bit 6 flag is used as an interrupt pointer for the AMU selection of a total status stream from one particular DLT.

Abstract: SCRAMBLING AND UNSCRAMBLING VIDEO SIGNALS IN A PAY TV SYSTEM Abstract of the Disclosure A scrambler scrambles a video signal by replacing its vertical intervals with dummy video signal lines, and separately providing information relating to the timing of the replaced vertical intervals. This information is encoded using an encryption key and is distributed with the scrambled video signal by modulation of the horizontal sync. pulses of the scrambled video signal. An unscrambler derives the information from the horizontal sync. pulses, which it regenerates, and decodes the information and uses it to generate a vertical interval of correct timing to replace the dummy lines of the scrambled video signal, thereby producing an unscrambled video signal reproducible on a conventional TV receiver. The scrambling is further enhanced by varying the number of dummy lines which are used to replace different vertical intervals, thereby producing a video signal of variable field length, which is not susceptible of recording. -i-
