Abstract: ABSTRACT OF THE DISCLOSURE The intake manifold for supplying air-fuel mixture from a single source to a plurality of cylinders of an internal combustion engine employs individual pipes all having the same cross sectional area but having different non-circular cross sectional contours.  Where less fuel is needed at low engine speed and power output, the bottom half of each intake pipe is formed with a small or internal radius of curvature than the top half.   Where more fuel is needed at lower engine speed and power output, the bottom half of the pipe is formed with a larger radius of curv-ature than the top half.  The purpose is to better equalize the distribu-tion of fuel to the cylinders under low speed and low power operation of the engine, without affecting fuel distribution at higher engine speeds.

A method for making a buttonhole in a piece of material using a zigzag stitch sewing machine wherein the lips of the buttonhole are formed by the alternate stitching of opposite fractions of the desired length of the two lips, the stitching always being carried out in the same direction, and this process being repeated until the desired length is achieved. The material is moved in the reverse direction in the period between-the finishing of one fraction of two opposite fractions and the starting of the other. The method is almost entirely automatic, all movements being regulated by interchangeable cams on the machine, and operator supervision is minimal.

Abstract: ABSTRACT OF THE DISCLOSURE       An apparatus and method of using same to form tubular tapered shafts particularly adapted for golf clubs, ski poles, fishing rods and the like.  The material used in forming the shafts is a thermo-setting resin sheet that has a number of elongate, laterally spaced, parallel fibers of graphite carbon, boron or like material therein, which fibers have a tensile strength comparable to steel, but are only a fraction of the weight of the latter.  The apparatus and method of using the same is characterised by the tubular shaft being formed with exterior and interior cylindrical wall surfaces that are truly concentric, and with the fibers embedded in the polymerized resin being pre-tensioned and spaced from one another.  The polymerized resin selected is one that effects a strong bond with the fibers, is more elastic than the material defining the fibers, and as a result the fibers absorbing the major portion of the load when the shaft is transversely flexed such as occurs when it is used as a component in golf clubs and fishing rods.  The apparatus is susceptible to being used with other resin impregnated load receiving materials such as powders, fabrics, cloth and the like, but the resulting tubular tapered shafts do not have the strength and operational advantages of shafts that embody graphite carbon or boron fibers as a part thereof.

Abstract: ABSTRACT            This invention provides a transversely excited travelling-wave gas laser in which the excitation pulse is shaped by a pair of elongate electrodes, the separation of which varies along their length.          The separation is ideally determined empirically.          Preferably, the laser has a pair of main discharge electrodes having a constant separation between which the lasing discharge occurs, and a pair of timing electrodes electrically in series with the main discharge electrodes, the separation of which varies such that the discharge between the timing electrodes provides a sharpened pulse that arrives along the main electrodes in such a manner as to obtain a travelling wave laser discharge.  The main and timing electrodes are preferably segmented.          The separation of the electrodes is determined empirically by bringing successive portions of the main discharge electrodes into alignment and varying the separation of corresponding portions of the timing electrodes to obtain the required timing characteristics.  The laser utilises a Blumhein-type circuit with a suitable switch.

Abstract: OPTICAL COMMUNICATION CABLE     Abstract of the Disclosure An optical communication cable comprises one or more cores of light-transmitting optical fibers substantially decoupled mechanically from the rest of the cable structure. Surrounding each core is an inner jacket which forms a loose-fitting enveloping structure about the core.  Surrounding the inner jacket or plurality of inner Jackets is an outer jacket which is reinforced with primary strength members to carry expected tensile loads and to thereby relieve the fibers of the core or cores as cable strength members.  The core fibers are also buckled into a slackened state under no-load conditions to allow for stress-free elongation of the core fibers during tensile pulling of the cable.  In one embodiment, each core comprise linear arrays of optical fibers packaged on a plurality of ribbon structures which are stacked and helically stranded for further strain-relief.

Abstract: ABSTRACT OF THE DISCLOSURE      A variable frequency AC source drives a gas discharge lamp which is connected in parallel with the capacitance of a series resonant circuit. The polarity of the voltage applied to the resonant circuit is commutated at such times as the rate-of-change of current flow in the resonant circuit is at or near zero. The source frequency is thus maintained at or near the circuit resonant frequency to maintain high output voltage when the lamp is starting or reigniting.           The polarity is also commutated at such times as the current flow from source reaches a predetermined level. Lamp current is thus controlled in the running mode.
