Abstract: Title: A TUBULAR LINING MATERIAL FOR PIPE LINE            ABSTRACT OF THE DISCLOSURE A tubular lining material for pipe lines having a relatively large inner diameter and possibly a plurality of bends or curved portions, which comprises a tubular textile jacket made of warps and a weft knitted or woven in a tubular form overlaid with an air-impervious coating or a flexible synthetic resin and is applicable onto the inner surface of a pipe line which has a relatively large inner diameter and may have a plurality of bends or curved portions in such manner that the tubular lining material with a binder onto the inner surface thereof is inserted into the pipe line and allowed to advance within the pipe line with or without the aid of a leading rope-like elongated material while turning the tubular lining material inside out under fluid pressure thereby applying the tubular lining material onto the inner surface of the pipe line with the binder being interposed between the pipe line and the tubular lining material, characterized in that the warps are comprised of crimped yarns of polybutylene tere-phthalate fibers and the weft is comprised of a crimped yarn or synthetic fibers. This tubular lining material is improved in biaxial stretchability, especially in lengthwise direction and has high flexibility and consistency so that the tubular lining material can be impregnated with a sufficient amount of a binder and applied onto the inner surface of the pipe line in good compliance with the shape of the inner surface without forming wrinkles of narrowing the flow path in bends or curved portions of the pipe line.

Abstract: ABSTRACT OF THE DISCLOSURE.          PROFILED SHEET MATERIAL.         The profiled sheet material is formed into side panels and floor or deck panels for use for example in the manufacture of high-sided lorries, trailers and containers    One object of the invention is to provide a profiled side which will present a substantially smooth outer surface and another is to provide a floor or deck of shallow depth but relatively high strength. The profiled sheet material (10) has a plurality of parallel deformations (11) which in cross section are substantially triangular with the base (12) of each deformation spaced from the body (3) of the sheet,  The apex (14) of each deformation is formed by closely abutting curved faces of the sheet material (10) where the body of the sheet material is bent into the deformation,  This sheet is used as a side plate.  Floor or deck plates incorporate strips of timber (50) whose longitudinal faces are tapered.   These are located between adjacent pairs of deformations (11) with the tapered faces abutting the respective sides (42, 43) of the deformations.   One method of forming the profiled sheet material (10) comprises the steps of passing the sheet material into a press to form a series of U-shaped channels (Fig. 3) therein one at a time.  A series of indents (41) are also formed along the length of the web (12) of the U-formation.  The U-formation is then deformed by pressing the tops of both limbs (42, 43) inwardly towards each other to form a triangular formation.

Abstract: ABSTRACT       The metal cluster cobalt carbonyl catalyst R3CCo3(CO)9, alone or promoted with Ru3(CO)12, wherein R3 is hydrogen; C1-12 alkyl, preferably C1-5 lower alkyl; C5-10 cycloalkyl or alkyl-substituted cycloalkyl; C6-12 cycloalkenyl, such as cyclohexenyl or cyclooctenyl; C1-12 alkoxy, such as methoxy or propoxy; C6-20 aryl or alkyl-, cycloalkyl-, alkoxy-, halo-, or cyano-substituted aryl; cyano; or a silyl carbyne moiety of the formula R34Si, wherein R4 is alkyl or aryl, effectively catalyzes the dealkoxyhydroxymethylation of aldehyde acetals to form glycol monoethers.     Methylal, for example, may be reacted with syngas; i.e., CO and H2, in the presence of this catalyst system to form the corresponding ethylene glycol monomethyl ether.  Cycloalkyl- and aryl-acetals, as well as alkyl-acetals of various aldehydes, as well as their aldehyde precursors, may likewise be reacted with syngas in the presence of these metal cluster catalysts to form the corresponding glycol monoether.       The novel catalyst combination of R3CCo3(CO)9 promoted with Ru3(CO)12 is likewise claimed herein.

Abstract: NAPKIN CONSTRUCTION WITH LAMINATE WRAPPER            ABSTRACT            A sanitary napkin is provided which obviates the problem of stain propagating across the body facing side of the napkin while still facilitates manufacturing processes. Specifically, the napkin comprises a pad having a wrapper which overlies the garment facing side of the pad, the longitudinal sides of the pad, and peripheral portions of the body facing surface of the pad.  The wrapper comprises a body fluid impervious sheet laminated to a fibrous sheet with the fibrous sheet being wider than the impervious sheet. The fibrous sheet has a width sufficient to overlie the garment facing surface, the longitudinal sides and the longitudinal peripheral portions of the body facing side of said pad, but is insufficient in width to overlie the central major portion of the body facing surface of the pad.

Abstract: A TAPE DISPENSING DEVICE          ABSTRACT        An ergonomically shaped tape dispensing and cutting device adapted to snap over a roll of masking tape or the like and be retained on the roll, affording a convenient tearing edge for severing the tape. The device is preferably a one-piece molded plastic article comprising a top wall which rides over the outer periphery of the tape roll and two flexible side walls which depend from the top section and flank opposite sides of the roll of tape when the invention is positioned on a roll of tape. A cutting blade may be fixed to or integrally formed with the dispenser. Inwardly projecting shoulders are fixed to the front bottom surface of the side walls in opposing spaced relation and serve to spread the side walls apart as the tape dispenser and cutter is pressed down over 8 roll of tape. As the shoulders clear the inner core of the tape roll, the shoulders are snaped back beneath the core of the roll and serve to retain the invention on the roll of tape. The top wall includes a thumb-receiving control recess to enhance control and stability. The side walls taper downwardly along an arc of a circle so that the device fits comfortably and securely in the apex of thumb and forefinger.

Abstract: WATCH PAGER SYSTEM AND COMMUNICATION PROTOCOL          ABSTRACT OF THE DISCLOSURE A wide area paging system can broadcast paging messages input in one local area to a receiver in any other  local  area.   A local  area clearinghouse  stores resident subscriber data including current location and receiver serial number.  This data is used to transfer messages over a data network to the correct clearing-house.   The  data  is  encoded  and  transmitted  in  256 bit/13 millisecond TDM data packets via stereo FM side-bands.   Receivers  are  assigned  sequentially  numbered time  slots  matching  part  of  their  address.    The addresses of intended receivers are included in the data packets.  Battery-powered receivers turn on and off just in time to receive an incoming packet in their assigned slot.   Long  messages  are  transmitted  in  two  or  more linked  packets.   A  watch  pager  employs  a  wristband antenna which electromagnetically couples to the user's body  and  displays  time,  telephone  numbers and  icons representing common types of paging messages.

Abstract: ABSTRACT OF THE DISCLOSURE     This invention provides a fastener having a shank with a relatively abrupt transition (34) from an unthreaded portion (33) to a full thread dimension (35), the thread runout (36) occupying no more than one pitch length of the thread in the axial dimension, and circumferentially extending no more than about one-fourth of the circumference of the thread at its pitch diameter. The counter-bore (42) of the nut (29) is reduced in length in light of the short transition section of the shank. The threads are rolled on the shank by opposed dies (55) having ridges (56) complementary to the thread to be produced which run out at one edge of the die with spaced, generally symmetrical end walls (60) which are relatively short axially of the ridges so that the full thread dimension is achieved abruptly.

The control means also has means for detecting whether the step to be performed by the step motor is a single remaining step or single step only.  The control means responds to detection of the single remaining step or detection of the single step only by applying a unit of energy to the step motor at a rate that is substantially slower than the rate that would be applied for the other steps.
