Title: High voltage subscriber line interface circuit
Inventor: PATEL LALIT O
IPC: H04M7/00
Filed: 1990-11-01
Abstract: A HIGH VOLTAGE SUBSCRIBER LINE INTERFACE CIRCUIT     ABSTRACT    A high voltage subscriber line interface circuit is disclosed which is connected via a subscriber loop to a subscriber station.  The subscriber line interface circuit of the present invention includes a tip and ring drive amplifier circuits that supply feed current to the subscriber loop.  A common-mode amplifier circuit connected to the subscriber loop senses the voltage dropped across the subscriber loop and outputs a control voltage to the tip and ring drive amplifier circuits. The control voltage offsets the feed current applied to the subscriber loop and develops a balanced longitudinal impedance.  A differential amplifier circuit connected to the subscriber loop detects and converts differential transmit voice signals into a single unitary output signal.  The unitary output signal is applied to an AC summing amplifier circuit where it is summed and combined with a receive voice signal that is intended to be transmitted to the subscriber station.  The resultant summed output signal is then applied to a phase splitter amplifier circuit.  The phase splitter amplifier circuit develops a pair of balanced output signals from the summed voice signals that are equal in amplitude but 180 degrees out of phase with each other.  Each of the output signals is connected to a respective one of the tip drive and ring drive amplifier circuits for transmission on the subscriber loop.  A tip-party mark detector circuit is also included that produces a logic signal output when a voltage difference between the output signal of the common-mode amplifier circuit and a reference voltage is detected.

Title: Process for the long term reduction of body fat stores, insulin resistance, hyperinsulinemia and hypoglycemia in vertebrates
Inventor: CINCOTTA ANTHONY H
IPC: A61K38/22
Filed: 1990-11-16
Abstract: A process for the long term modification and regulation of lipid metabolism -- generally to reduce obesity, insulin resistance, and hyperinsulinemia or hyperglycemia, or both (these are the hallmarks of noninsulin dependent, or Type II diabetes) -- by administration (i.e., by feed or injection into the bloodstream) to a vertebrate, animal or human, of a dopamine agonist, e.g., bromocriptine. Administration of the bromocriptine is made over a limited period at a time of day dependent on the normal circadian rhythm of fat and lean members of a similar species. Decreases in body fat deposits result by treatment of an obese species on a daily timed sequence based on circadian rhythms of the peak prolactin, or peak prolactin and peak glucocorticosteroid, blood level established for lean members of a similar species. Insulin resistance, and hyperinsulinemia and hyperglycemia, or both, can also be controlled in humans on a long term basis by treatment corresponding to that of the treatment for obesity. The short term daily injections reset hormonal timing in the neural centers of the brain to produce long term effects.

Abstract: A clutch mechanism includes a ferromagnetic anvil having an axial bore for axially receiving a pin; a cup axially aligned with the anvil for receiving a pin that is axially receiving by the bore of the anvil, wherein the anvil is longitudinally movable along its bore axis with respect to the cup; a spring for forcing the anvil toward a confining end of the cup; balls in the cup for engaging the pin when the anvil is forced toward the confining end of the cup, with the balls being disposed to apply radial pressure against the pin to firmly clutch the pin and thereby restrain the pin from longitudinal movement when the balls are forced toward the confining end of the cup; and a ferromagnetic shield disposed axially in relation to the anvil for diffusing magnetic flux applied axially to the anvil by a magnet external to the clutch mechanism so as to prevent less than a predetermined amount of the axially applied magnetic flux from overcoming the spring and forcing the anvil to move away from the confining end of the cup.  The clutch mechanism further includes a radially disposed pole piece for directing magnetic flux applied radially by a pole piece coupled to the magnet so that at least a predetermined amount of the radially applied magnetic flux is so concentrated axially in the anvil as to overcome the force of the spring and force the anvil to move away from the first end of the cup.

Title: Continuous solvent pulping and washing processes and apparatus
Inventor: GREENWOOD BRIAN F
IPC: D21C11/00
Filed: 1991-05-17
Abstract: ABSTRACT      A continuous solvent pulping process is practiced with oxygen free gas (e.g. nitrogen) purges of all major treatment vessels during the time when the process is arrested or terminated.  The wood chips or other cellulosic fibrous material to be pulped is steamed in a first horizontal steaming zone at a pressure of about 10-20 psi, and then in a second horizontal steaming zone at a pressure of about 20-75 psi.  The first and second zones are isolated by a low pressure feeder.  Steam is introduced into the material in the second steaming zone to flow co-currently with it.  Gases, including vaporized solvent (e.g. ethanol or other alcohol) are vented from the steaming zones, and solvent is added to the steamed material prior to feeding to a high pressure feeder.  The high pressure feeder introduces the material into the top of a single digesting vessel, liquid and chips being separated at the top of the digester vessel without mechanical means that could cause a spark.  Lignin containing liquid is withdrawn from a central portion of the digester and passed through flash tanks and ultimately for lignin and alcohol recovery.  A recirculating screen and system is disposed between the central extraction portion and the top of the digester vessel.  A portion of the liquid removed for recirculation is instead passed to lignin recovery, while fresh solvent containing liquid is added to the rest of the recirculated liquid.  Washing -- which also may be practiced using solvent pulp from a batch system --is accomplished by first continuously passing the pulp to a pressure diffuser, then to a first multi stage drum displacer washer, and then to a second multi stage drum displacer washer.  In the pressure diffuser the lignin is washed out of the pulp, utilizing as wash liquid a mixture of solvent and water having a solvent concentration equal to or higher than that required by the extraction process within the digester, and at a pressure at at least about 350 psi.  The pressure in the second and third stages is lower, and water is the wash liquid in the third stage.  Alcohol can be recovered from the spent wash liquid of the first wash stage, so that all but about ten gallons or less of alcohol per ton of pulp is recovered.

Title: Contact component
Inventor: STORK PETER
IPC: H01T4/06
Filed: 1991-09-26
Abstract: Contact component. Attached to a base part (5), the contact component (1) has a clamping adapter (3) and a fork spring contact (6) with which it can be plugged onto pin-shaped mating contacts (14, 15, 16). With respect to an axis of symmetry, proceeding in plug-in direction, of the fork spring contact to be contacted with the mating contact, an offset (v1 or v2) is provided for a clamping point (4) of the clamping adapter (3) in a first direction proceeding perpendicularly to the axis of symmetry and in a second direction proceeding perpendicularly to the first direction and to the axis of symmetry (2). Each contact component (1) is firmly inserted in various positions in a base housing part. This occurs in reception chambers which are provided in the shape of a grid at a certain dividing distance.      The insertion in various positions of the contact components (1) provided with the offset enables the generation of contact configurations for the contact pins of electrical modular units or components which deviate from the arrangement of the reception chambers. For example, component contact pins arranged in one line can be converted to a mating contact arrangement aligned in a triangular shape. Generally, a conversion from a line to a grid is possible, or respectively, from a one grid to another grid with a different spacing. This feature also encompasses the expanding of two pin rows having a preset distance to two pin rows having a large distance from one another and vice versa.

IPC: G01W1/00
Filed: 1991-10-11
Abstract: A humidity sensor (1) having two heatable humidity electrodes (11, 12) is assigned a temperature sensor (7) which is in thermally conductive contact with one (11) of the humidity electrodes. The heating circuit of the humidity electrodes is activated when a first desired temperature value of 0 DEG C is undershot at the temperature sensor. By varying the heating current, the temperature sensor is maintained at the first desired temperature value over a prescribed time interval. Thereafter, the sensor temperature is regulated in a second prescribed time interval as a function of the ambient temperature between the first desired temperature value and a second, higher desired temperature value. An evaluation circuit generates a switching signal when a sensor temperature characteristic of ice formation is reached and a guide value characterising humidity is overshot between the humidity electrodes (11, 12). Electrodes (11, 12, 13), heating resistors (R1, R2) and temperature sensor (7) are embedded in a plastics dielectric (6) which fills up a sensor housing (4) and ends at a low level with respect to the housing edge at an opening side while forming a liquid reservoir. <IMAGE>
