Abstract: Abstract of the Disclosure A method of splicing an optical fiber is described. The fiber arrangement comprises a plurality of fibers secured to a ribbon-like tape.  The fiber segments to be spliced are mounted on the slideable holders of a splicer such that each of the fibers of one segment are aligned approximately co-axially with a fiber on the segment.  The individual fibers are then cut, as required; moved into position; more accurately aligned by mechanical means; and then bonded to-gether by the application of either heat or a bonding material of suitable refractive index.  In one arrangement, accurate alignment of the fibers is obtained by means of a grooved cover plate which is placed over the adjacent ends of the fibers and left in position until the bonding step is completed. Various means for mounting the fiber segments in a splicer and for strengthening the splice are disclosed.  A modified splicer for liquid core fibers is also described.  The method of the invention permits optical fibers to be spliced quickly and economically, thus making optical fibers more suitable for practical application.

Abstract: ABSTRACT         Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with a novel superactive multimetallic catalytic composite comprising a combination of a catalytically effective amount of a pyrolyzed rhenium car-bonyl component with a porous carrier material containing a uniform dispersion of a catalytically effective amount of a platinum group component which i  maintained in the elemental metallic state.  In a highly preferred embodiment, this novel catalytic composite also contains a catalytically effective amount of a halogen component.  A key feature associated with the preparation of the subject catalytic composite is reaction of a rhenium carbonyl complex with a porous carrier material containing a uniform dispersion of a platinum group metal main-tained in the elemental state, whereby the interaction of the rhenium moiety with the platinum group moiety is maximized due to the platinophilic (i.e. platinum-seeking) propensities of the carbon monoxide ligand used in the rhenium reagent.  A specific example of the type of hydrocarbon conversion process disclosed herein is a process for the catalytic forming of a low octane gasoline fraction wherein the gasoline fraction and a hydrogen stream are contacted with the subject superactive multimetallic catalytic composite at reforming conditions.

Abstract: DIESEL ENGINE STARTING CONTROL              Abstract of the Disclosure A starting control for a fuel injected diesel engine retards movement of the fuel injection control rack out of the starting position by a degree which varies with temperature to improve the starting characteristics of the engine without interfering with normal operation of the fuel injection system and its control rack.  Movement of the control rack out of the starting position in response to the increasing force exerted by the governor on the control rack coupled floating lever of the fuel injection system is resisted by a damper in the form of a dashpot having a plunger coupled to the floating lever.  The dashpot may be coupled to the floating lever by a pivotable crank and a pair of magnets respectively mounted on the crank and the floating lever, the magnets eventually separating to remove the starting control from the fuel injection system when the opposing forces of the governor weights and damper become great enough due to increased engine speed or when the crank reaches an adjustable limit stop.  The dashpot plunger which has a one-way check valve mounted therein is quickly returned to the initial position in preparation for restarting or subsequent starting by a spring coupled to the crank.  Alternatively, the dashpot plunger is coupled to the control lever by linkage which includes a spring.  In this arrangement the starting control not only improves engine starting but also acts to damp and retard rapid motion of the control rack into higher load positions during normal operation so as to minimize unburned fuel and thereby greatly reduce smoke and other air pollution.  The amount of retardation provided by the dashpot varies with temperature which in turn varies the viscosity of oil within the dashpot.

Abstract: ABSTRACT OF THE DISCLOSURE           The electromagnetic disk-free clutch includes a cylindrical rotor supported on one rotary part and defining at one end face a frictional disk and at the other end face an annular groove which accommodates a tubular stator with an elec-tromagnetic coil.  The frictional ring of the rotor faces a corresponding frictional ring of a spring-biased armature which is supported for joint rotation and for an axial displacement on the other rotary part.  The stator part adjoining the open end of the annular gap is radially extended to form a covering flange having a cross section substantially equal to the cross section of the axially directed parts of the stator and the rotor.  The face of the rotor forming the frictional ring is provided with uniformly distributed openings and the axial dimension of the annular goove in the rotor exceeds that of the stator.  The resulting air gap between the bottom of the annular groove and the stator prevents the formation of attractive forces acting on the stator in axial direction and the openings in the end portion of the rotor cause a compression of the magnetic flux before it enters the armature.
