Abstract: EDGAR MALCOLM STUBBERSFIELD              and LESLIE VICTOR SHAW               ABSTRACT OF THE DISCLOSURE     A notching tool for forming notches in ridge- or hip-capping for roofs, the notches being formed to match the profile of the roofing sheets.       The tool has a base with a pair of spaced feet i which engage the ribs on the roofing sheets to align the tool.  A notching head on the base has a replaceable die and punch pair, one of which is fixed to support the capping while the other is manually or power-operated to provide a shearing-type cutting action between the die and punch to cut the notches.  Adjustable guides on the notching head support the capping for angular alignment between the capping and the notching head and for adjustment of the depth of the notch.  The notching head may be pivotally and/or rotatably mounted on the base and the die and punch may be reversible.

Abstract: ABSTRACT OF THE INVENTION         Relatively long plastic microfilaments made from a plastic composition are described.  The plastic micro-filaments may be used to make reinforcing, filler materials and fabrics.      The microfilaments are made by forming a liquid film of plastic across a coaxial blowing nozzle 5, applying a blowing gas 10 at a positive pressure on the inner surface of the plastic film to blow the film and form an elongated hollow tube or cylinder shaped liquid film 12 of plastic.        Means are provided for forming a thinned wall or weakened portion of the plastic film forming the wall of the elongated tube or cylinder.  A transverse jet 13 is used to direct an entraining fluid 14 over and around the blowing nozzle 5 at an angle to the axis of the blowing nozzle.  The entraining fluid 14 as it passes over and around the blowing nozzle 5 fluid dynamically induces a pulsating or fluctuating pressure filed at the opposite or lee side of the blowing nozzle in the wake or shadow of the coaxial blowing nozzle and produces a laminar flow of entraining fluid in the vicinity of the forming elongated tube or cylinder.  The continued movement of the entraining fluid 14 over the elongated tube or cylinder 12 produces asymmetric fluid drag forces on the tube or cylinder, and at the thinned walled or weakened wall portion longitud-inally breaks the tube or cylinder to form a multiplicity of plastic microfilaments, and detaches the plastic mic-rofilaments from the elongated tube or cylinder and from the coaxial blowing nozzle and the detached microfilaments are carried away from the blowing nozzle.         Quench nozzles 18 where the plastic is thermo-plastic and heating nozzles where the plastic is thermosetting may be disposed below and on either side of the blowing nozzle 5 to direct cooling fluid or heating fluid 19 at and into contact with the plastic micro-filaments 17 to cool or heat and cure, solidify and harden the plastic to form hard, smooth plastic micro-filaments 17.

Abstract: COIN OPERATED MECHANISM            ABSTRACT OF THE DISCLOSURE            Coin  operated newspaper sales  cabinets  conventionally are  provided  with   a   coin-return   facility.    The invention  seeks  to  avoid  the complexity   of  known coin-return mechanisms.  It is known to provide a  latch plate mounted  on  a  pivot  for tipping to unlatch  the door.    The   invention   uses  the   plate   and   its already-provided  tipping ability to deflect coins  into a  coin  return  tray  when  the  coin-return  lever  is operated.  A  subsidiary  hook  or   latch   comes  into operation when the coin return lever  is operated, so as to hold the door  closed.  The  simplicity of  the whole coin mechanism is  greatly enhanced now  that  the means for diverting the  returned coins has been provided just by  extending  the   motion  of   an  already  existing component.   For  example, the  manner of  mounting  the coin-check  pawls  is simplified: so  is  the manner  of providing the  facility  for changing  from  weekday  to Sunday prices: and so is  the construction  of the means to burst open the coin-chutes to release jammed coins.

The mold is then filled with material constituting the separating body, wherafter the mold is removed.
