Abstract: ABSTRACT OF THE DISCLOSURE           The present invention provides a selvage-forming device for use in a weaving apparatus,which selvage-forming device is of a relatively simple construction and yet effect-ively forms the selvage.   The device comprises a rotatable plate upon which is mounted first and second supplies of thread.   The thread from each supply of the same is prefer-ably fed to a pre-guide member, through a guide means at the extremity of a tensioning arm, and through an aperture in the rotatable plate.   The rotatable motion of the plate will cause the selvage threads to form the desired selvage.

Abstract: SPEAKER DIAPHRAGM AND METHOD    OF MAKING THE SAME         Abstract of the Disclosure The present invention relates to a speaker diaphragm constructed by forming a boron layer on one face of a dome-shaped metal foil.  The layer is formed by means of a physical vapor deposition method such as ion-plating, cathode sputtering, vacuum evaporation or the like.  When necessary, the metal foil is thinned by etching, and then, if necessary, another boron layer is formed on the other face of the metal foil.          Alternatively, a metal layer is formed on the surface of the boron layer.  The resulting speaker diaphragm is light in weight and high in specific modulus of elasticity and also has appropriate internal mechanical resistance against vibration.  As a result the speaker according to the present invention is of a high efficiency and has satisfactory characteristics.

Granted: 1980-04-22
Abstract: ABSTRACT OF THE DISCLOSURE           In accordance with the present invention, there is provided an improved arrangement for and method of electrically testing a cord-set during the molding of the male plug and female receptacle to the opposite ends of the insulated electric cord.  In order to accomplish this, the mold for forming the molded plug and receptacle is provided with suitable contacts which upon the closing of the mold automatically establish electrical connections between the terminals of the cord-set and circuits in testing apparatus.  These tests consist of checking for continuity in each conductor and for shorts between conductors or terminals and a skin ground test for the purpose of detecting stray strands of wire or any current carrying object that would carry current to the outside surface of the molded plug or receptacle.  For the latter test, the metal of the mold itself, which closely embraces the entire outer surfaces of the plug and receptacle,  serves as the ground as it is in contact with any conducting particle which extends to the outer surface.

Abstract: ABSTRACT OF THE DISCLOSURE         Porous film materials composed of polytetrafluoro-ethylene, having an asymmetric structure and suitable for industrial use in mass transfer operations is disclosed, as is a process for producing the materials by stretching the film using a pair of revolving rolls which are heated to a temperature lower than the melting point of the film.  Stretching is produced by revolving the two rolls at different speeds which also tends to produce a compressive force in the thickness of the film.  The rolls are heated to different temperatures to produce a tempera-ture difference of preferably 50C or more.  The combination of the compressive force and the temperature gradient in the thickness of the film is believed to produce the asymmetric structure in the resulting porous film materials which are characterized by a fiber structure in the front surface which is different from that in the back surface.

Abstract: ABSTRACT OF THE DISCLOSURE     A fuel injection pumping apparatus includes a governor which controls the size of an orifice through which fuel is supplied to an injection pump to determine the amount of fuel supplied by the pump to an associated engine,  The governor includes a piston which at one end is subjected to fuel press-ure and which bears at its other end against a spring connec-ted in series with a spring.  The spring is weaker than the spring so that at idling speed it is the spring which balances the force acting on the piston. Manually operable means is provided to effect movement of an abutment disposed between the springs, the spring acting to determine the maximum speed of the associated engine.  When the engine has been started from cold, it is desirable to provide additional fuel to enable the engine to idle properly and for this purpose a device represented by the arrow, moves the end of the spring remote from the spring and this provides a temporary increase in the amount of fuel supplied at idling speeds.
