Abstract: ABSTRACT         An order wire system which can be used during installa-tion and maintenance of an optical fiber communication system comprises an optical fiber order wire to which engineers can connect at remote sites communication sets each of which includes a microphone and earphone allowing the engineers to communicate with each other.  Full duplex and multi-party operation can be achieved with the sets according to the invention and, because the signals are regenerated, the range of operation is considerable.       Both analog and digital communication is contemplated and different specific circuits are proposed.  In a typical analog configuration, the microphone output is fed to first and second frequency modulators operating respectively at first f1 and second f2 centre frequencies.  The outputs of the modulators are summed and passed to a laser driver and laser which is optically coupled both to the upstream and the downstream side of the order wire.          Optical detectors are respectively connected to the upstream and downstream sides of the order wire and the outputs of these are fed through first and second bandpass filters to respective frequency demodulators.  One of the filters passes only f1 frequencies and the other only f2 frequencies.  The outputs of the demodulators are fed to the earphone and also back to the respective modulators for regeneration.

Abstract: Abstract of the Disclosure METHOD AND APPARATUS FOR MAKING RUBBER ARTICLES     Indefinite length tubular and sheeting products can be fabricated using either a continuous or step-wise method which uses a two-stage curing sequence.  In the first curing stage, the center portion of a thermosetting web is fully cured leaving the lateral edges of the web in an uncured state.  The uncured lateral edges are then spliced, either directly to one another, or spliced with a similar web having uncured edges to form either a flat sheet or a tubular preform having longitudinal uncured spliced seams.  In the second curing stage, these uncured longitudinal splices are fully cured to form either tubular articles or flat sheeting having completely uniform physical properties throughout.

Abstract: ABSTRACT OF THE DISCLOSURE        There is disclosed connectors for physically and optically connecting optical fibers to one another.  This is accomplished by providing a sleeve member with first and second coaxial cylindrical surfaces.  The first cylindrical surface of the sleeve member is an internal surface arranged to engage the cylindrical outer surface of the lens means.  The axial length of the region of contact of the cylindrical outer surface of the lens means and the first cylindrical surface of the sleeve member is short.  The cooperation of the sleeve member with the lens means locates the position of the latter axis transversely of the datum axis within the sleeve member and the shortness of the axial length of contact of the surfaces allows small freedom of the datum axis to tilt relative to the sleeve member.

Abstract: Abstract An electromagnetically-actuated positioning mechanism for opposed spring-biased reciprocating valve  actuators in displacement machines, having an electromagnetically-actuated adjusting solenoid device for shifting the locus of  equilibrium  of  the  actuators'  spring  systems  at startup.   While  the  position  of  equilibrium  is  pre-determined  when  the  adjusting  solenoid  is  in  the energized state,  it is unnecessary for valves to be in the fully closed position when the adjusting solenoid is in  the  non-energized  state.    In  the  position  of equilibrium as shifted by adjusting device, the distance of a gas exchange valve from one of the two operating positions  is  approximately  10%  to  40%  of  the  total distance between the two operating positions, and is at least  partly  open.    The  invention  is  particularly applicable to lifting valves and sliding gate valves, and for valves in internal combustion engines.

Abstract: Abstract of the Disclosure A connector for an immersible electric device such as a pump motor substantially precludes water leakage in an area where the wires enter a motor housing.  The connector is comprised of a elastomeric body portion  having a relatively non-resilient plate secured thereto, and passageways extending through the body portion and the plate complementally receive the electrical wires.   The body portion and the plate are installed in a mating bore of the motor base such that the plate is seated against an inwardly extending shoulder within  the bore.  The connector also includes a steel bracket adjacent the body portion and remote from the plate, and the bracket has barbed arms which are received in smooth walled slots in the base, thereby enabling the arms to be shifted to a position wherein the bracket, in combination with the plate and the bore walls, exert a compressive force on the resilient body portion to force the latter into sealing en-gagement with not only the bore walls but also into fluid-tight relationship with the outer surfaces of the electrical wires.  In preferred forms, the body portion has outwardly extending projections sur-rounding the wires, and the bracket has openings complemental to the projections such that the walls defining the bracket openings compress the projec-tions against adjacent portions of the wires to create a secondary seal.

Abstract: Abstract Apparatus for indicating the timing relation-ship between a reference point of a repetitive input signal, e. g. the horizontal sync point of a video signal, and a signal element that repeats at a higher frequency than the input signal, e. g. an element of the color burst, comprises a phase-locked oscillator for generating a continuous wave signal that is in phase with the signal element. The continuous wave signal is used to generate a train of pulses having a repetition frequency that is equal to the repetition frequency of the signal element and is selectively variable in phase rela-tive to the continuous wave signal, and this train of pulses is used to modulate a display of the repetitive input signal in a dimension other than one that is used in a normal waveform display, e.g. intensity.  By alternately bringing the pulse train into phase with the reference point of the input signal and the higher frequency signal element, the phase relationship between the signal element and the reference point can be determined from the required phase adjustment.

Abstract: This invention relates to a method and an apparatus for the production of ribbed pipes. The apparatus comprises a core (8, 9, 10) which together with an extrusion sleeve (4) forms a nozzle (11) through which a plastic material is fed into a moulding space (12) defined between a mandrel (9) and chill moulds (1, 2) moveable with respect to the mandrel. Ribbed pipes produced by means of known apparatuses have, for various reasons, an uneven inner face, incomplete ribs or air closures and weak seams in the pipe walls and ribs. These disadvantages can be eliminated by such a dimensioning of the moulding space (12) of the apparatus and the grooves (13) of the chill moulds that the volume of a space defined between a plane (20) extending adjacent to the end face of the extrusion sleeve, a surface (16) of the mandrel, and a plane (17) comprising the envelope surface of the kernel (10) equals to the combined volume of the grooves (13) positioned within the area of the mandrel at each particular moment.

Abstract: A wire magazine for winding wire for use in a winding machine for winding of protracted materials or cores, preferably closed cores, comprises two ring-shaped half pieces 9, 10, which are thin-walled with essentially semicircular cross section to produce a largely closed supply space. The half pieces are separated by a wire filling slot 11 lying on the outside of the magazine and a bottom slot 12 facing the axis of rotation on the inside of the magazine, which is bounded by edge parts of the two half pieces 9, 10 so that its walls are not plane parallel with the central plane in the wire magazine, which is perpendicular to the axis of rotation. With this configuration of the wire magazine one achieves the best possible residual hole ratio for the winding of ring cores, while at the same time assuring an effective securing of the winding wire in the magazine after the cutting of the wire, and furthermore one achieves an improved security against slippage of the wire as it is being drawn out. <IMAGE>
