Abstract: A unitized sealed thrust bearing includes two annular races (12) and (14) with a complement of bearing balls (16) therebetween. One race (12) includes an axially inwardly extending central cylindrical flange (24) and the other race (14) includes a pair of elastomeric sealing lips (36) and (38), one 36 of which is bonded to the outer edge of the race and the other (38) of which is bonded to the inner edge of the race. The central flange (24) includes an unobstructed radially inwardly facing wall (26) and a radially outwardly facing wall (28) with a radially and axially inwardly facing sealing surface (32) terminating in a radially outwardly extending rib (34). The inner sealing lip (38) includes an outer sealing wall (42) which in its undeformed state slopes axially and radially inwardly at a greater angle than the sealing surface (32), and an axially inwardly facing shoulder (44) at the terminus thereof. 
     As the races (12) and (14) are moved axially together during assembly, the sealing wall (42) of the inner lip (38) flexes as it slides past the rib (34) and into engagement with the sealing surface (32), and the shoulder (44) moves adjacent the rib (34) and the outer sealing lip (36) engages the other race (12). Axial separating movement of the races (12) and (14) engages the shoulder (44) with the rib (34) to compress the inner lip (38) and retain the races (12) and (14) In their assembled condition.

Abstract: An oven (1) is mounted on balances (2) and comprises an intermittently charged filling device (14) which continuously feeds the crucible (13) of the oven. The jet of molten inorganic material (3) leaves the oven (1) continuously through a casting hole (4) and falls onto a rotor (5) coupled to a driving device (6). The air flow responsible for conveying and dispensing the fibres into the blade chamber is produced by the system (12). A sensor (8), preferably a pyrometric camera, transmits a signal representative of the temperature of the jet (3) to the calculating system (9) which determines its viscosity. The flow rate of the jet (3) is calculated from measurements of the weight of the oven (1) supplied by the balances (2). These measurements are carried out e.g. between the operations of recharging of the filling device (14). A control device (7) determines, as a function of optimum operating data calculated by the system (9) from the viscosity of the jet flow, the speed of rotation of the spinner wheels and the quantity of the air ensuring the conveying of the fibres. <IMAGE>

Abstract: A current is measured by making use of a rotation of polarization plane in a magnetic field, that is, a Faraday effect. A conductor (20) under measurement is transversely inserted into a center opening of a Faraday effect glass (13) which has at least two total reflection areas on a periphery thereof so that a light directed into the Faraday effect glass is circulated around the conductor and emitted externally. The light emitted from the Faraday effect glass is split into at least two light beams, which are converted to electric signals by photo-electric elements, and A.C. components contained in the electr'c signals are extracted and compared. The electric signals are corrected based on the comparison result. 
     The present measuring apparatus and method attain high precision current measurement in a stable manner over an extended period.

Abstract: Disclosed is a closed loop control system for an optical recording apparatus of the read after write type comprising a comparator (20) for comparing the input data signal with a playback signal derived from the read beam (25) which trails the write beam (24) and is modulated by the data pattern inscribed on the recording medium by the write beam (24). The error signal generated by the comparator (20) is applied to a controller (22) which varies the modulation of the write beam (24) in dependence on the error signal, for example, by modifying the data signal used to drive the write beam modulator (5). In this way, the control system compensates for nonuniformities in the recording medium and the like so as to ensure that the pattern inscribed by the write beam (24) accurately represents the data to be stored.

Abstract: A drive shaft (41) is disclosed of the type having first and second sets of axially-disposed external crowned splines (39 and 43) for transmitting torque betwee first and second sets of internal straight splines (37 and 45). The sets of internal straight splines are relatively transversely disposed such that the drive shaft is disposed during operation at a running angle (A) relative to the axis (79) of the internal splines. Each of the external crowned splines includes a pair of tooth flanks joined at a root radius having a radius (R). The root radius (R) is related to the running angle (A) of the drive shaft by the equation
     In this equation, C is a constant for the particular drive shaft design, and is determined empirically to yield a minimum circular clearance between the external spline and the adjacent internal spline. With the present invention, it is possible to determine the appropriate root radius for each of a series of different drive shaft applications, having different running angles, while maintaining the desired circular clearance.
