Abstract: ABSTRACT OF THE INVENTION     A bladder mandrel utilizing a sleeve of Pellethane? to effect tube expansions is disclosed herein. The sleeve which forms the bladder of the mandrel terminates in sealing beads which include fluid-cupturing recesses. When the beads of the sleeve are secured within grooves provided in the mandrel body, pressurized fluid flowing through the fluid port of the mandrel enters the fluid-capturing recesses of the beads and sealingly engages these beads within their respective grooves. The sleeve consequently fills with the pressurized fluid, and effects the desired tube expansion. The walls of the sleeve are thinnest at their center portion, and become progressively thicker toward the sealing beads. The use of a Pellethane? sleeve having a centrally disposed thin-walled section results in a bladder mandrel having a relatively small outer diameter, which in turn allows it to be inserted within a tube without the need for lubricants. Additionally, the invention includes a * for conveniently detaching the sealing beads of the sleeve from the body of the mandrel when replacement of the sleeve is necessary.        * pair of grooved joints

Abstract: ABSTRACT OF THE DISCLOSURE         An information medium adapted to be written by thermo-optical   means   comprising   a   heat-sensitive structure adapted to store  information to be read by optical means.  This includes a thin metal layer, which, when incident writing radiation impinges on it, causes a transient   localized   temperature   rise.     Above   a temperature  threshold  this  causes  a  change  in  the optical characteristics of the heat-sensitive structure. The  information  medium  is  manufactured  by  a  method involving   depositing   a   continuous   thin   film  of polycrystalline aggregate over an acceptor surface of the aforementioned structure by means of an  incident flux of particles of a precious metal and a transition metal.     In  order  to  obtain  a  defined  metallic composition, these metal particles are extracted from at least  one  target  exposed  to  bombardment  by  other particles resulting from an electrical discharge in a rare gas at reduced pressure and confined by a magnetic field.    The  acceptor  surface  collects  these  metal particles with a residual energy content giving rise to a density of nucleation sites increased relative to that for a similar deposit obtained by vacuum evaporation. The maximum distance between the target and the acceptor surface is preferably not more than twenty centimeters, and advantageously not more than ten centimeters.

Abstract: ADAPTIVE FILTER UPDATE   GAIN NORMALIZATION          Abstract Update gain normalization is employed in adaptive filters to control weighting of the filter impulse response updates in order to converge properly to a desired impulse response.  Singing, i.e., oscillating, of the filter is overcome by adjusting the update gain when an incoming signal power estimate used to normalize the gain exceeds a prescribed threshold value.  In one example, the normalized gain is adjusted to be a fixed value for power estimate values which exceed the threshold.  In accordance with another aspect of the invention, a single normalized gain value is used to adjust the update gain in two adaptive filters employed as echo cancelers in a bidirectional voice frequency repeater.

Abstract: Abstract of the Disclosure Fiber Optic Seam Tracking Apparatus An arc welding head suitable for robotic welding has a fiber optic bundle and remotely located laser light source which is imaged onto an end of the fiber optic bundle and optically linked to substantially a single fiber of the fiber optic bundle.  The light source is then repetitively scanned across the coherent arrangement of fibers within the bundle, such that, a substantial portion of the transmitted light will be sequentially delivered to each individual fiber within a row of fibers and subsequently delivered to a workpiece.  This arrangement provides a high signal to noise ratio making the laser light reflected from the workpiece easily distinguishable from the optical "noise" generated by the welding arc flash.

Abstract: Abstract An interface circuit for coupling a parallel data device to a serial data channel over which Manchester-type codes are transmitted.  In the interface circuit, an efficient and reliable Manchester decoder comprising a flip-flop an exclusive-or gate and at least one delay line separates the data and clocking signals.  The serial data signals are clocked into a serial register under control of the external clocking signals from the channel.  A carrier detector enables the serial register only when valid information signals are present.  A parallel data register receives in parallel the data from the serial data register.  To get in phase the external clocking signals with the internal clock source, an internal clock synchronizing circuit recycles the internal clock source upon the occurrence of a synchronizing character that is transmitted over the serial data channel.  In this fashion, the internal operations of the parallel data transfers are in phase, but isolated from the external clocking signals so that in the event that the external clocking signals become corrupted due to noise or simultaneous transmissions of information signals by different devices, the internal parallel transfer operations may continue freely without disruption.

Abstract: 23                  49,578 ABSTRACT OF THE DISCLOSURE Protective  relay  apparatus  for  providing  a compensated fault impedance measurement for the determina-tion of a better estimate of fault location along a trans-mission  line  is disclosed.   In an power  system network including local and remote generating sources disposed at respective  ends  of  a  transmission line  segment of the transmission  line,  the  protective  relay  apparatus  is disposed at the local end of the line segment to measure the fault impedance for use in determining fault location. However,  load flow conditions rendered by the generating sources interact with a fault which contributes resistance substantially to the fault impedance of the transmission line to cause an erroneous component in the fault impedance measurement rendering the determination of  an erroneous fault location.  The protective apparatus disclosed gener-ates a signal as a measure of this erroneous component and compensates the fault impedance measurement as a function of the erroneous component signal,  a predetermined imped-ance characteristic of the transmission line segment,  and the fault impedance measurement to provide the compensated fault impedance measurement.

The first mounting element is connected to an upper clamping section which cooperates with a lower clamping section to engage around a tubular to be plugged. The upper section can be correctly centered with its plug over the port of the tubular by momentarily compressing the bellows to extend the plug. The plug is provided with a shank portion and a breakable tab for breaking the plug away from the shank portion. The shank portion is connected to the rod so that after the plug is seated in the port the rod, its mounting elements and the clamp section can be removed from the insulated steam injection tubing.

Abstract: RF-AM TRANSMITTER WITH  PULSE WIDTH MODULATOR                      Abstract An  RF-AM transmitter  includes  a  pulse amplifier responsive to a pulse width modulated (PWM) signal derived in response to an information signal.  A low pass filter converts pulses derived by the power amplifier into a variable amplitude signal that is DC coupled to a power supply for an RF amplifier.  An amplifier system including the pulse and RF amplifiers has stray capacitance coupled to a modulator which derives the PWM signal; the stray capacitance lengthens narrow modulator output pulses so they are excessively long.   The amplitude of only the narrow pulses is reduced by a resistor-capacitor timing circuit in series with a switch to substantially preserve the narrow pulse area.  The switch provides a low impedance path from the timing circuit to a reference potential terminal when current initially flows in the circuit during pulse transitions and throughout the length of each of the short duration pulses.  Thereby, the power amplifier  is  forward biased  but  not  driven  into saturation during the short duration pulses.   The switch provides a higher impedance path from the timing circuit to the reference potential terminal after the transition has elapsed enabling the power amplifier to be saturated during pulses longer than the short duration pulses.   The RF power amplifier tube has a tendency to load the power amplifier tube out of saturation during wide pulses.   The ampitude of the wide pulses is maintained substantially constant by a resistor shunted by an inductor between the modulator and the power amplifier.
