Abstract: IMPROVED SEISMIC ARRAY     ABSTRACT OF THE DISCLOSURE         An improved seismic array is provided which has the capability to supply data to adjacent recording stations simultaneously.  The seismic array has a plurality of seismic detector connection points, and a seismic detector is located at each seismic detector connection point.  Dual weighting of the output of each seismic detector in the array is achieved by connecting dual resistors to the output of each seismic detector.  Two pairs of wires are also provided in the array, and one pair of wires interconnects one weighted output of each seismic detector to the first end of the array.  The second pair of wires interconnects the second weighted output to the second end of the array.          An amplifier is provided for use at either or both ends of the array, and a feedback network, including a resistor, is associated with the amplifier.  The ratio of the value of the resistance in the feedback network to the weighting resistor at the seismic detector determines the magnitude of the signal appearing at the output of the amplifier from the response of that seismic detector.  A Chebychev weighted array is achieved by a proper selection of resistor values.

Abstract: ABSTRACT OF THE INVENTION              A permanent magnet generator that minimizes the effect that temperature would otherwise have on the output current when the generator is operating under a heavy current load.  The permanent magnet generator includes a stator having a plurality of teeth and slots between adjacent teeth with at least one winding having electrical conductors passing through the slots, and a strip of ferromagnetic material positioned in at least one of the slots and electrically isolated from the conductors.  The ferromagnetic material has a Curie point in the range of 300 to 600°F.  The invention provides for a reduction in the inductive reactance of a winding of the generator as temperature increases over its operating temperature range so that the effect of temperature on the output current of the generator is minimized.     pc/

Abstract: TITLE                    ENERGY SAVING FLUE DAMPER                           INVENTORS                      Terrence J. MASSE and Fouad BARSOUM                           ABSTRACT           Disclosed is a flue damper mechanically driven through a sensor control to change the physical position of a damper within a flue associated with a furnace or other combustion device.  By means, after the demand for ignition of the furnace, the flue damper is rotated slowly into the full open position whereupon ignition of the furnace is permitted.  After the demand has been satisfied, the ignition is ceased and at a predetermined time thereafter the damper is slowly moved to the closed position whereby to inhibit completely, in the cases of oil fired devices, and to a substantial degree (a maximum of 90%), in gas fired devices, the orifice size of the exhaust flue thereby preserving the residual heat within the boiler or fire box which would otherwise escape through the flue into the atmosphere.          Such device decreases, in excess of 15%, the amount of energy consumed by reducing the cool-down effects of the fire box or boiler.  The device also stops migration of warm air from the building through the fire box into the flue and its escape into the atmosphere.  The latter problem is really more severe in water retaining boilers (hot water heating) and particularly so, where, the heated environment or building is controlled by so called "zone" techniques, wherein, by the control mechanism of the furnace the boiler is maintained within a predetermined range of temperatures, and the thermostats which control the heating into the various zones of the premises call on and off heat by activating a circulation pump.

Abstract: ABSTRACT:             High-pressure sodium vapour discharge lamps having a colour temperature of 2250 to 2750 K and a colour rendition index Ra of 60-85 emit light of a strongly reduced Ra already after approximately 2000 hours in oper-ation.  As compared with the life of normal, yellow high-pressure sodium vapour discharge lamps, this period is very short.  The discharge vessel contains sodium, mercury and a rare gas, the weight ratio Na/Hg being from 1/1 to 1/9 and the sodium pressure during operation of the lamp being from 4 x 104 to 10.7 x 104 Pa.  The rare gas pressure in the discharge vessel at 300K is between 1333 and 1333 x 102 Pa. By using an emitter which contains oxygen-bound strontium and oxygen-bound tungsten in a molar ratio from 3/1 to 50/1, the initial properties of such white-light-producing lamps are maintained for a long period of time.

Abstract: ABSTRACT OF THE DISCLOSURE      Pancreatin pellets are produces by a process employing extrusion techniques.  In the process, a mixture of pancreatin powder and selected solvent is formed into a pliable mass suitable for extrusion. The extrusion is conducted followed by a cutting, shaping or forming of the extruded mass into pre-pellet like forms.  Further drying and mechanical working of the pre-pellet forms results in the final pancreatin pellet of improved pharmaceutical and mechanical stability.  A special aspect of the process is the selection of a solvent for mixing with pancreatin powder that is harmless to enzymes. Such solvents typically include isopropanol and acetone.

Abstract: ABSTRACT OF THE DISCLOSURE           A method of manufacturing a sound box of a stringed musical instrument, particularly a violin.  The method comprises subjecting the top and bottom plates of the sound box to stress causing an arc-shaped configuration having a curvature opposite to the curvature normally produced by the stretched strings of the finished instrument. In a preliminary step the side members are bent to form a side rim and battens are cemented thereto.  The side rim is elastically bent to the desired final configuration and the top and bottom plates are bonded to the side rim.  The stress is then released whereby the top plate is tensioned to produce improved acoustical properties in the sound box.

Abstract: FABRICATION TECHNIQUE FOR THE PRODUCTION       OF DEVICES WHICH DEPEND ON MAGNETIC BUBBLES            Abstract Magnetic bubble devices having planar geometry are produced by a particular sequence of processing steps. This sequence of processing steps includes the sequential deposition on a garnet material of an insulating material, an electrically conductive material, a second insulating material, and a material such as permalloy.  The upmost layer is then patterned by conventional techniques.  The pattern thus produced is used as a mask and the exposed underlying insulating layer is removed.  The exposed metal conducting layer is then patterned and etched in a pattern different from that of the permalloy and second insulating layers by a process such as selective plasma etching that does not substantially degrade the exposed dielectric material or the permalloy.  The results are a device with layers having planar geometry.

Abstract: 49,009 ABSTRACT OF THE DISCLOSURE         A circuit breaker includes a digital electronic trip unit having a microprocessor.  The front panel of the trip unit includes a potentiometer connected across a ref-erence voltage, and a numeric display device.  The poten-tiometer is adjusted by an operator to enter a value of a parameter defining the time-current characteristic of the circuit breaker.  An analog-to-digital converter receives the voltage supplied by the potentiometer and converts it to  a  digital  quantity for use by the microcomputer in performing limit checks with the current flow through the contacts of the breaker.   The microcomputer formats the converted digital value of the potentiometer voltage and supplies it to a front panel-visible numeric display so that the value of the potentiometer setting as interpreted by  the microcomputer  in defining the  time-current  trip characteristic  is  presented on  the  numeric  display  to provide real-time feedback to the operator as he adjusts the parameter value.

In one embodiment, the recycle serves as the conveying gas and in another embodiment as the purge stream.
