Abstract: ABSTRACT:     Current stabilizing circuit arranged between a first and a second common terminal (5 and 6), the circuit comprising a first circuit formed by the series arrangement of a first PNP-transistor (T1) and a second NPN-transistor (T2), and a second circuit formed by the series arrange-ment of a third PNP-transistor (T3), a fourth NPN-tran-sistor (T4) and a first resistor (R1).  The commoned bases of the second and fourth transistors (T2 and T4) are driven by a first differential amplifier (3), whose non-inverting input is coupled to the collector of the second transistor (T2) and whose inverting input is coupled to a tap (7) of a voltage divider (R2,R3) formed by a second and third resistor.  The commoned bases of the first and third transistors (T1 and T3) are driven by a second differen-tial amplifier (4), whose non-inverting input is coupled to the collector of the third transistor (T3) and inverting input to the tap (7) of the voltage divider (R2,R3).       Because of the drive by means of the first and second amp-lifiers (3 and 4), the collector-base voltages of the first and third transistors (T1 and T3) and of the second and fourth transistors (T2 and T4) vary to an equal extent in the event of supply voltage variations, as a consequence of which the symmetry of the circuit is preserved.

Abstract: Abstract of the Disclosure An apparatus for reproducing a signal recorded, in the form of a perpendicular signal magnetization, on a perpendicular magnetic recording layer backed with a high permeability layer of a magnetic recording medium.          A thin-film magnetic material is disposed to face the recording layer so that an enlarged magnetized region is formed in the high permeability layer, which includes the position at which the magnetic material faces the recording layer.  In this region, magnetic variation occurs in response to the signal magnetization of the recording layer at the position the magnetic material faces the recording layer.  A detecting member such as a coil is disposed in the proximity of the magnetic material so as to be magnetically coupled to the enlarged magnetized region of the high permeability layer.  The detecting member is used as a tuning element of a tuning circuit supplied with high frequency energy.  An resonance output voltage of the high frequency circuit varies in response to the detection of magnetic variation in the high permeability layer.  A reproducing circuit detects the variation in the resonance output voltage of the high frequency circuit to reproduce the signal recorded on the recording layer.

Abstract: MATERIAL VAPOR DEPOSITION TECHNIQUE            Abstract Deposited layers are advantageously obtained by utilizing a specific vapor deposition procedure. In this procedure, a substrate is positioned a relatively short distance from the source of a gas flow capable of producing the desired deposition.  This gas flow is directed so that it contacts an interior region of the substrate and moves from the initial contact point to a point on the periphery of the substrate.  Exemplary of such gas flow configurations is the positioning of a substrate at a small distance above a fused quartz fruit through which the deposition gas flow is directed.

Abstract: Abstract of the Disclosure Disclosed is an improved process for encapsulating core materials, particularly viable cells, within a membrane of controlled porosity.  A polyanionic polymer, e.g., sodium alginate, is formed into shape-retaining gel masses.  The gelled masses are then expanded by hydration, and a membrane is formed by reaction at the surface of the expanded masses with a polyanionic polymer having a molecular weight greater than 3000.  The expansion step promotes the formation of continuous, uniform capsule membranes of more consistent permeability resulting in a more reproducible cell encap-sulation process.

Abstract: PULL OUT FUSIBLE SWITCHES          Abstract of the Disclosure Assembly systems for compact N-pole fusible pull out switches of different ratings use the same two part insulator bases and the same insulator pull out heads in all switches.  In one system, for switches of a given current rating but two different voltage ratings, there are two types of fixed contacts in the base but the contacts are the same for both voltage ratings; the fuseholder/stab contact members in the head are all the same for both switch ratings, and all mounting hardware and incidental hardware is the same for all switches.  The voltage ratings are differentiated from each other only by different base terminals and by different insulator barriers over the base contacts.  In another system covering six switch ratings (three different current ratings and two different voltage ratings) the two part insulator bases, the insulator heads, and the base terminals are all the same and all mounting hardware and incidental hardware is the same for all rating combinations; the six different voltage/current ratings are differentiated from each other only by different fixed contacts in the base, by different fuseholder/stab members in the head, and by different insulator barriers.  The second system has only three set of fixed contacts each used for two different rating combinations.  Both systems preclude misassembly and misapplication in the field.  A particularly compact fuseholder/stab construction is provided for high current ratings.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention concerns a foldable head rest which provides elevated support for a person's head while lying in the prone position at the beach or other leisure place, for example.  The head rest may be easily carried in a folded flat configuration in one's luggage or hand and quickly unfolded for use at the beach.     The head rest broadly comprises a pair of rectangular frames including an interior and exterior frame each having two sets of two offset but parallel leg portions.  Cross members join the opposite leg portions of each frame at their otherwise free ends.  Fabric panels are secured to the respective cross members of the opposite frames including a top panel which provides direct support for the head and a bottom panel which supportively contacts the sand or ground to prevent the head rest from sinking into the sand or ground.     Each set of leg portions of each frame are tangent above and below respectively, to a central hub.  Each central hub and extensions therefrom further comprise a multitransitional portion which serves as a means for pivotal connection of the frames as well as a interface for the rotating frames during opening and closing of the head rest.     A hinge shaft, depending inwardly from the central hub of the exterior frame, is inserted through a centered hole of the central hub of the interior frame to pivotally connect the frames.  To prevent the internal and external frames from laterally separating when in the open position, protruding lobes depend from the ends of the hinge shafts and key shaped arrangement. The hinge shafts are rotated within the keyhole shaped centered holes upon unfolding the head rest thereby positioning the lobes in a locking fashion within the centered holes.     Stops are integrally formed by the abutment of the offset leg portions with the multitransitional portion of the frame whereby further rotation of the frames and unfolding of the head rest is restricted upon engagement of the stops of the exterior frame with the stops of the interior frame.     The fabric panels are folded upon themselves and stored within the rectangular frame when the head rest is folded. Unfolding the head rest, the fabric panels become taut and extend between the frames.  The head rest may be used such that either panel serves as the top panel.

Abstract: ROASTED COFFEE EXTRACT  DECAFFEINATION METHOD       ABSTRACT OF THE DISCLOSURE A roasted coffee extract decaffeination method providing a soluble coffee of improved flavor is disclosed.  A roasted coffee extract is contacted with a caffeine solvent so that caffeine and a lesser amount of non-caffeine solubles is transferred to the solvent.  The two liquids are separated and the caffeine solvent is typically concentrated.  The concentrated solvent is then contacted with an aqueous caffeic acid suspension so that caffeic acid/caffeine complex crystals grow in the water phase.  The complex crystals are filtered and the then at least partially decaffeinated caffeine solvent is separated from the water phase.  Contact of the caffeine solvent and an aqueous caffeic acid suspension may be repeated to achieve further decaf-feination.  Then, the solvent, which contains substan-tially only non-caffeine solubles, is added to the substantially decaffeinated roasted coffee extract. The caffeine solvent is then stripped from the roasted coffee extract, which is subsequently dried.
