Abstract: Abstract of the Disclosure A dual motor linear actuator is disclosed for use in a magnetic disc drive device.  It includes a carriage reci-procatably guided between a pair of guide rails, with the accessing transducers being mounted to its inner end. Separate rectangular drive coils are affixed in symmetrical outboard relationship at the sides of the body of the carriage. The actuator assembly further includes two pairs of slab shaped magnets mounted to E-shaped magnet support structures that are integrally formed with the base of the disc drive device.  The magnets are mounted to form two air gaps that are symmetrically disposed relative to a center plane and so that they respectively cooperate with the drive coils to apply motive forces on the carriage generally along two lines that are equidistantly spaced from the aforesaid plane of symmetry. The outer ends of pole pieces of the two magnet support structures are rigidly interconnected by a single plate that acts as an end pole piece for both magnet support structures.

Abstract: INDUCTION FURNACE MONITOR ABSTRACT OF THE DISCLOSURE The specification discloses a computerized monitor for a coreless induction furnace.  The monitor includes a first potential transformer connected across the coil and a second potential transformer connected between one end of the coil and an electric ground.  The relative location of a ground fault along the length of the coil is determined by computing the ratio of the transformer outputs.  The monitor further includes a first current transformer in the coil power line and a second current transformer in the melt bath ground.  Internal ground faults are detected by computing the phase difference between the coil and ground currents. A graphic representation of the furnace is also generated to illustrate the location of the ground fault with respect to turns and yokes of the coil.  The monitor also calculates liner wear by determining melt bath volume, which is inversely proportional to melt bath resistance, which in turn is pro-portional to coil resistance.  If the furnace being monitored is provided with more than one coil, a differential current transformer is connected across each coil to detect the fault grounded coil when the transformer associated with the faulted coil exhibits a substantially nonzero output.

Abstract: Abstract:    An exceptionally effective technique has been developed for desulphurizing hydrocracked petroleum pitch containing organic molecules having at least some chemic-ally bound sulphur.  Particles of petroleum pitch and a para- or ferromagnetic material catalyst are intimately mixed and this mixture in the presence of hydrogen is subjected to microwave radiation so as to generate a high intensity oscillating electric field thereby releasing at least part of the chemically bound sulphur from the pitch as sulphur-containing gases without substantial increase of the temperature of the pitch and separating the sulphur containing gases thus formed.  To avoid temperature rise during desulphurization, the microwave irradiation is preferably gated in a train of short pulses.

Abstract: ABSTRACT          ZINC-BROMINE BATTERY WITH LONG TERM STABILITY    A zinc-bromine  secondary battery having a recirculating electrolyte uses an array of cells in series with a parallel fluid flow through the several cell spaces along the confronting  electrodes.   The intermediate electrodes are bipolar with their cathode face having a coherent porous mass of binder-free charcoal particles of stable dimensions and configuration lightly pressed into electrical contact with it and with each other.  Spacer means holds the particles off from contact with the confronting anode face.   A single electrolyte flows through each cell with a flow path divided so that a high speed and throughput major portion bypasses the charcoal particles and a minor portion branches therethrough.  The zinc-bromine molarity of the electrolyte is preferably 0.5-1.5 at full charge and 2 to 4 at deep discharge and preferably only about 1% by weight of the molecular bromine present is in circulation with the remainder trapped in the electrode assemblies at all times.  The cell has a minimum long-term system degradation,  has limited self-discharge and has low environmental hazards.

Abstract: ABSTRACT OF THE DISCLOSURE       Since an ordinary semiconductor laser heretofore employed has no mechanism for stabilizing the lateral mode, the light emitting region becomes wider as current increases.  That is, the lateral oscillation mode is un-stable.  In the present invention, a current rejecting layer and an etch-back preventive layer are added to a semiconductor laser provided with a cladding layer composed of a projecting portion for confining light from an active layer and a portion for emitting light.  The thicknesses of predetermined layers, the relationships of forbidden band widths of the layers and their conductivity type are specified.  By these measures, an excellent current limit function and optical guide function can be obtained and the lateral mode can be stabilized.
