Abstract: Abstract of the Disclosure A phase locked circuit according to the present invention includes means for multiplying a signal to be phase locked by an integer N.  A resettable divide counter divides the multiplied signal by N for return to a phase comparator.  Reset means operates the resettable counter upon command so that when the input signal to the phase locking circuit is changed (i.e., between two signals each having approximately the same frequency but which may be out of phase), the reset means is operated to reset the divide counter so that the maximum phase error of the signal delivered to the phase comparator is .pi./N radians.

Abstract: APPARATUS FOR THE PRODUCTION OF CONTACT LENSES    AND PROCESS FOR THE UTILIZATION THEREOF                 THOMAS H. SHEPHERD     ABSTRACT OF THE DISCLOSURE     There is provided a mold comprising a male and a female mold member fabricated from thermoplastic polymeric materials which, in very thin sections are flexible under polymerization conditions, but, under said conditions are sufficiently inflexible in thick sections to retain their shape and surface characteristics.  Said mold is provided, on either the male or the female member with a thin rim which, during the polymerization process, flexes and permits the mold members to approach each other and compensate for the shrinkage that occurs during polymeriza-tion.  Said thin rim further forms the edge of the finished lens.

Abstract: PROCESS FOR PRODUCING MESOPHASE PITCH                 ABSTRACT OF THE DISCLOSURE           An improved process for producing pitch which is transformed, in part, to a liquid crystal or so-called "mesophase" state.  According to the process, the meso-phase content of the pitch is formed while agitating the pitch so as to produce a homogeneous emulsion of the immiscible mesophase and non-mesophase portions of the pitch.  Mesophase pitches prepared in this manner have been found to possess a lesser amount of high molecular weight molecules in the mesophase portion of the pitch and a lesser amount of low molecular weight molecules in the non-mesophase portion of the pitch, and thus a smaller differential between the average molecular weights of the mesophase and non-mesophase portions of the pitch, than mesophase pitches having the same meso-phase content which have been prepared in the absence of such agitation.

Abstract: ABSTRACT OF THE DISCLOSURE . -For a sheet-metal bending press of the kind in which the coaction of a die and a punch causes the metal plate to be bent at an angle, a device is provided, which is capable of detecting the angle of bend of the plate being machined in a continuous way and of generating a signal which has a magnitude proportional to the angle width.  The signal can be used either as a conti-nuous angle-checking means, or for driving the automatized operation of the press, or for both function.  The necessity of removing the plate to be bent angularly in order to check the angle progressively produced is entirely eliminated.  A zero method can be adopted for taking readings when the front surface of the detector proper of the angle is not exactly coplanar with the resting surface for the plate on the press bed.

The improvement comprises a rotatable compressor stator casing which is interconnected with the power turbine rotor to allow rotation of the compressor casing in the same direction as the compressor rotor at a lower speed.  At reduced output shaft speed, the relative speed between the compressor rotor blades and stator blades is increased for increased gas generator output and hence torque, while the compressor rotor speed remains constant.

Abstract: COMBINATION INSULATING SLEEVE AND ELECTRICAL    CONTACT MEMBER FOR ELECTRO-PLATING RACK     ABSTRACT OF THE DISCLOSURE  A pressure sensitive electrical contact member which surrounds a first electrical conductor and completes an electric connection between the first conductor and a second electrical conductor in response to relative pressure exerted thereon by the two conductors.  As an example, the pressure sensitive electrical contact member may be used as an insulating sleeve which surrounds that portion of an electro-plating rack upon which the articles to be plated are supported.  The sleeve includes a pressure sensitive electrical contact portion which is normally nonconductive but becomes conductive when the article to be plated is placed on the rack so as to complete an electrical connection between the article and the rack.  Because only substantially that portion of the pressure sensitive electrical contact that the article contacts is electrically conductive, the effects of parasitic plating on the rack are greatly minimized.

Abstract: ABSTRACT           A roller bearing cartridge and a method of making the same.  The bearing cartridge is constructed with an outer race assembly constructed of two identical parts, centrally joined together, such that openings are provided for a locating pin and for the passage of lubricant re-gardless of the type of housing in which the bearing cartridge is used, which housings have lubrication fittings and cavities for locating pins in locations which differ from one another.           The locating pins restrict relative rotation between the outer race which is constructed with an arcuate outer surface and the housing which has the opening defined by an arcuate surface to receive the bearing cartridge. The restricted relative rotation is between the bearing cartridge and the housing and is such as to provide sufficient relative rotation to permit the bearing assembly to be self-aligning to accommodate shaft misalignment relative to the housing support.           In that locating pins may be sheared off by severe shaft misalignment, there is also disclosed a con-struction limiting self-alignment relative rotation between the bearing cartridge and the housing to some predetermined amount.
