Abstract: CONSTANT VELOCITY UNIVERSAL JOINT In a constant velocity universal joint an inner joint member fits into a cavity in a hollow outer joint member and a cage, positioned between the two joint members, has windows which guide a number of torque transmitting balls positioned in oppositely aligned grooves formed in both of the joint members. The case is formed as one-piece and has at least one cut-out opening extending in the direction of the alignable axes of the joint members. The cut-out opening extends from one end disposed transversely of the axis of the joint members to at least a transverse plane containing the window surfaces of the cage which are more remote from the one end of the cage.

Abstract: ABSTRACT OF THE DISCLOSURE:         The process according to the invention uses a matrix engraved by any means, the tracks being perfectly centered on this matrix in relation to a center of rotation.  The matrix is placed in a vacuum chamber on a supporting axis capable of rotating and is coated over its entire surface with a poly-merisable material which is free from air bubbles and which does not adhere to the constituent material of the matrix.  A substrate previously drilled at its center, balanced and coated with a material to which the polymerisable material adheres, is placed on the supporting shaft and held at a distance from the matrix.  The vacuum is established in the chamber and the substrate is brought into contact with the matrix.  On completion of polymerisation outside or inside the chamber, the substrate carrying the moulded resin is readily separated from the matrix.

Abstract: Abstract of the Disclosure Apparatus for constructing a plurality of wire trusses on a continuous basis includes an endless conveyor belt carrying a plurality of assembly blocks movable successively by the conveyor belt along a desired line.  The assembly blocks each have an outer flat surface which, in move-ment of the blocks along the line, lie in a common plane parallel to the line. The several blocks define in their flat surfaces a plurality of pairs of grooves which extend parallel to the line of block movement.  The adjacent pairs of grooves are more closely spaced to each other than are the grooves constituting each pair.  The grooves in each block are aligned with the grooves in the other blocks.  Also, the flat surface of each block has at least one groove which extends diagonally to and which intersects the parallel grooves.  The apparatus includes a feeding mechanism for feeding wires longitudinally into the grooves which are aligned with the direction of movement of the conveyor blocks, and dispensing means for inserting discrete lengths of wire into the diagonal grooves so that wires disposed in the diagonal grooves contact the wires disposed in the parallel grooves. The apparatus includes welding units for welding each d the diagonally disposed wires to the wires in the alingned parallel grooves while all the wires are moving with the conveyor belt.  A cutting assembly is disposed along the line of movement of the conveyor belt downstream of the welding units for cutting the diagonal wires in the grid between the longitudinal wires of adjacent pairs.

Abstract: Abstract of the Disclosure A transducer positioning system (15) for a rotating magnetic disk memory unit (20, 30) in which servo positioning information is interspersed with data. The disk comprises concentric data tracks (37) individually divided into spaced data sectors (40). Two sets of radially extending blocks (44) of servo information are recorded between each pair of adjacent data sectors (40). Adjacent blocks in each set (44) produce asymmetrical pulse trains that are the time-displaced complements of each other. A first set of blocks (45) are positioned radially so that their boundaries lie on the data track centerlines. Each block in the second set (46) is aligned with a data track. A transducer positioning device (31, 32) utilizes the first blocks of information to maintain the transducer (30) in alignment with a track and tile first and second blocks of information in moving the transducer from one track to another.

Abstract: ABSTRACT OF THE DISCLOSURE       An elastomeric enclosure is initially inflated to a desired pressure by a gas having large molecules incapable of diffusing outwardly from the enclosure, except at a relatively slow rate.  When the enclosure is surrounded by ambient air at atmospheric pressure, such air passes into the enclosures by reverse diffusion, thus extracting energy from the ambient sea of air to progressively increase the total pressure in the enclosure to a substantial extent over a period of several months, the pressure then decreasing very slowly over an extended period to its initial inflation pressure, such extended period being as much as about two years or more.  This added energy may be used to perform useful work or used in various pneumatic devices to achieve essentially permanent inflation.  Decrease in pressure below the initial inflation value continues at a very slow rate over an additional period of many months, and, in fact, several years, with the inflation pressure still remaining at a sufficiently high value which enables the inflated enclosures to still possess a useful life.

Abstract: TITLE OF THE INVENTION:     CIRCUIT ARRANGEMENT FOR COMPARING THE SYNCHRONISM OR TRACKING BETWEEN TWO ANALOG SIGNALS            ABSTRACT OF THE DISCLOSURE:     The synchronism or tracking between two analog signals is compared by a circuit arrangement having two inputs to which these analog signals are applied.  A comparator cir-cuit compares the two signals and provides a trigger or energizing signal to a switch which in turn produces an error signal when the two compared signals deviate from each other to an extent larger than a predetermined limit.          One input is connected to the comparator circuit through a heterodyning circuit wherein the respective analog signal is heterodyned by a heterodyning signal which varies in its polarity.  The comparator circuit includes a polarity de-tector which provides a signal signifying a positive or a negative difference between the amplitudes of the two polarity signals.  A discriminator circuit is operatively connected to the comparator to provide a switch energizing signal when the difference signal does not have any zero transitions or passages with the frequency of the hetero-dyning signal.

Abstract: 53                  48,252 ABSTRACT OF THE DISCLOSURE         A turbine speed control system comprising a pair of  concurrently  operable  electronic  microprocessor-based controllers which are coupled together by a data link to functionally cooperate in controlling turbine acceleration primarily during start-up operations in accordance with a set of predetermined measured and calculated turbine condi-tions.  One controller is operative to control the speed of the turbine at selected accelerations from turning gear to a predetermined speed value.  This same controller monitors a plurality  of  temperature  differences  from preselected regions of the turbine and inhibits turbine acceleration in accordance  with  an  out-of-limit  temperature  condition associated therewith.   In addition, the one controller is further operative to selectively override the turbine speed hold initiated by an out-of-limit temperature condition, the override permitting the one controller to proceed with controlling the speed of the turbine at a desired accelera-tion.   The  other  controller is selectively operative to govern the turbine acceleration as controlled by the one controller  based  on  calculated  present  and  anticipated rotor  stresses  which  are  derived  concurrently with  the speed control operations of the one controller.

In either case, the one controller is further operative to detect if the speed hold occurs in one of a number of predetermined critical speed zones and to adjust the turbine speed out-side of the zone in which the speed hold occurs.
