Abstract: DEVICE FOR REMOVING MOLDED MATERIAL FROM MULTI-PLATE MOLDS     Abstract of the Disclosure A device for removing molded articles and cured sprues from the cavity and cover plates, respectively, of a multi-plate multi-cavity injection mold, includes a molded article ejection unit and a sprue extraction unit which, when the molding machine is opened, are juxtaposed, respectively, to a space between the mold cover and cavity plates and to a space between the mold cover plate and the face plate of the injection unit of the machine.   A common carrier unit is provided for shifting the article ejection and sprue extraction units jointly into and out of the said spaces.  In a preferred construction, the article ejection unit includes a plurality of ejector pins for the mold cavities, and means responsive to the arrival of the ejection unit at the end of its in-stroke for causing the ejector pins to penetrate the cavities from one face of the cavity plate.  A trough-shaped guide unit movable with the ejection unit but into juxtaposition to the other face of the cavity plate is also provided, to define a guide chute for the ejected articles.  The sprue extraction unit includes a rotatably driven roller which during its in-stroke is in rubbing or wiping contact with the outside face of the mold cover plate for pulling the cured sprues therefrom.  This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.

Abstract: ABSTRACT           An article comprising a heat-recoverable conduit is provided with a plug or cap within or around said conduit to prevent the ingress of contaminants.  The plug or cap comprises two principal parts; the first part, which is hollow, sits inside or around the conduit and the second part, which is attached to or in engagement with the first part, blocks the conduit.  The second part can be detached or disengaged before recovery so that, for example, a supply line can be passed through the conduit and the first art can then be removed, destroyed or deformed prior to or during recovery.  The plug or cap may also act to prevent premature recovery of the conduit.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of hot mix recycling of old asphaltic concrete paving heats the old pavement, after it has been removed and sized, to a temperature below its firing point and heats fresh aggregate to a greater temperature before combining the two and adding new asphalt. The method is embodied in a drum-mixer type of apparatus modified by inserting a smaller drum in the upstream portion of the large drum. The burner fires into the smaller drum into which the fresh aggregate only is introduced while the old mix (plus additional fresh aggre-gate in certain cases) is introduced into the annular space between the two drums, the fresh aggregate and the old mix being thereafter combined in the large drum, new asphalt added and the mix further heated.

Abstract: APPARATUS FOR BREAKING AN OPTICAL FIBRE Abstract of the Disclosure A tool for breaking an optical fibre comprises an elongate base member and an elongate top member pivotally connected at a rear end.  An elongate cam member slides longitudinally in the base member, being actuated by pivotting of the top member.  At the front end of the base member are a front pair of opposed gripping jaws and a further, rear, pair of gripping jaws are spaced from the front jaws.  A bending member is positioned between the two pairs of jaws. Pivotting of the top member towards the base member actuates the cam member which in turn first closes the front jaws, then the rear jaws. The rear jaws then pivot backwards to tension the fibre and then the bending member moves up to cause the fibre to bend over an arcuate top surface.  Finally a pivotally mounted scoring member in the top member is actuated to sweep a sharp edge across the fibre to initiate a crack, which propagates across the fibre.           - i -

Abstract: ABSTRACT          This invention relates to a multi-cell battery which includes a plurality of frames formed of a mouldable material which is electrically insulating at the intended oper-ating voltage of the battery and is inert to the active materials of the battery and any material produced during operation of the battery.  Each frame defines a plurality of separate material receiving areas arranged in side by side relationship across the width of the frame and each frame includes portions forming divisions between adjacent support areas of the frame.  The frames are arranged in a side by side relationship in a direction normal to the width of the frame with the portions of each frame forming the divisions between adjacent receiving areas secured in a sealed relationship to the corresponding portions in adjacent frames to form partitions between adjacent cells of the battery.          Each alternate frame has an electrolyte porous separator member spanning each support area thereof and secured to the portions of the frame defining the support area.  Individual masses of active battery material are supported in each support area of the remaining frames so that each said area forms a plate of the battery.  The active battery material in respective areas is selected so that adjacent areas in each frame form plates of opposite polarity and adjacent areas on opposite sides of each separator member form plates of opposite polarity.  Each said alternate frame has a plurality of spacer elements integral there-with, the spacer elements being arranged so that each spacer member has at least one spacer element extending partly across that surface of the separator member directed to the support area of an adjacent frame carrying active material of positive polarity.

Abstract: METHOD AND SYSTEM FOR MONITORING THE          ANGULAR DEFORMATION OF STRUCTURAL ELEMENTS     Abstract of the Disclosure A method and system for monitoring the angular deformation of structural elements in a composite structure in response to imposed mechanical vibrations in which the structure is part of the monitoring system.  A plurality of angular motion signal generating sensors are provided at different selected locations in a composite structure, each sensor being associated to a corresponding structural element.  Signals output from the sensors in response to vibrations propagated within the composite structure are detected and a vibration signature for the entire structure is established.  The sensor outputs are subsequently monitored and compared with the previously established vibration signature to detect differences therebetween designating changes in the vibration response and potential structural failures.  The angular motion sensors employ a magnet and a coil in which a voltage and current are induced in response to angular deflections of the structural member to which the sensor is attached.          Several alternate sensor configurations are shown.
