Abstract: OPTICAL FIBER PROOF TESTING EQUIPMENT Abstract of the Disclosure Optical fiber proof testing equipment has a rotary drive and two pulleys directly coupled to the drive.  A fiber is taken from fiber drawing equipment around part of the circumference of the first pulley, along a guide track and around part of the circumference of the second pulley.  Respective continuous belts apply a resilient bias to clamp the fiber to the pulleys, the resilient bias being adjustable The second pulley is marginally greater in diameter than the first pulley so as to establish a predetermined tensile stress in fiber moving between the two pulleys.  The test equipment is used after fiber has been drawn in a drawing tower and then coated and before the fiber is stored on reels.  The tensile force on the fiber can be changed by changing the diameter of the first or second pulleys.  In addition some incremental change in the tensile force can be obtained by adjusting the resilient bias provided by the continuous belt.                             - i -

The free end of the rotor assembly has a male phone plug,  The innermost end of the rotor assembly has an enlarged head with a transverse face supporting a plurality of concentric electrical contact rings that are insulated from each other.  A circuit board is clamped within the housing, and it has a first plurality of spring wire contacts that are each urged into continuous wiping contact with a separate one of the concentric rings.  A second plurality of spring wire contacts are mounted to the circuit board within the female socket for making contact with a standard male phone plug.          The housing is provided with partitions to provide spacers between the first plurality of spring wires and separate partitions for providing spacers between the second plurality of spring wires so as to retain these contact elements in place.  The location of this rotatable connector relative to the coiled telephone cord has many possibilities.  The connector can be at either end of the cord, or intermediate the length of the cord, or built into the handset.

Abstract: A FOLDING BELT SYSTEM AND SAID BELT A folding belt system having the head (13) and tail (12) pulleys twice the width of the support idler rolls and having a transition length of about 7 to 15 times the width of the belt between the fold or hinge lines, where transition width support rolls are located. The folding conveyor belt is composed of a central belt section which has specially constructed flexible areas at each edge extending longitudinally the length of the belt to which are attached cover flaps (34 or 46). The cover flaps completely enclose the load while it is conveyed. This reduces spillage, dust, and contamination while providing highly enhanced conveying capacity. The flaps may be of the same or different construction than the center section of the belt. In it's preferred embodiment the fold belt is constructed by suitably providing the top cover of a fully cured conveyor belt with longitudinal grooves (30) formed by slitting and removing a strip of rubber at the appropriate locations to form preferentially flexible longitudinal hinge areas in the belt with the dominions outside the hinges comprising the cover flaps (34), Alternately the hinge areas (44) can be molded into the belt at the time of manufacture.

Abstract: IDLE CONTROL METHOD FOR AN INTERNAL COMBUSTION ENGINE             ABSTRACT OF THE DISCLOSURE    A method of controlling an air-fuel ratio of an air-fuel mixture for an internal combustion engine includes the steps of sensing the intake air temperature and the operating state and rotating speed of the engine using various detectors.  When the intake air temperature is above a predetermined temperature, when the engine is in the idle operating state, and when its rotating speed is below a predetermined speed, the control circuit ceases a normal control in which the air-fuel ratio of the air-fuel mixture is controlled to be a value in a theoretical air-fuel ratio range, and instead controls the air-fuel ratio to be a predetermined rich air-fuel ratio.  With this method, a decrease in the absolute amount of fuel supplied to the engine due to a reduction in intake air quantity in the idle operating state when the intake air temperature is high is avoided, which in turn prevents a reduction in the rotating speed of the engine and ensures stability of idling.

Abstract: COMBINED CHECK AND EXHAUST VALVE              ABSTRACT OF THE DISCLOSURE A gas spring unit having a housing, and a piston assembly slidably supported within and projecting outwardly of the housing.  The housing and piston assembly cooperate to define therebetween a pressure chamber which is precharged with a high pressure gas, specifically nitrogen, for absorbing external shock forces as imposed on the piston assembly.  A first passage, containing a one-way check valve, extends through the end cap of the housing to permit charging of the pressure chamber with high-pressure gas, and to additionally permit make up gas to be supplied to the chamber.  A second passage extends through the end cap for relieving pressure within the pressure chamber, such as due to overload or when relief of pressure is desired.          A movable discharge valve is associated with the second passage, and the opening and closing of the discharge valve is controlled by a control piston which is slidably disposed within the end cap and has opposite ends thereof exposed to the pressures within the first and second passages for controlling the position thereof, and hence controlling the position of the discharge valve.
