Abstract: DEVICE IN GRINDING APPARATUS               ABSTRACT OF THE DISCLOSURE       A grinding apparatus in which lignocellulose-containing material such as wood chips is ground in a grinding space defined between cooperating disc segments carried by a rotating disc and a stationary disc in close spacing tolerance.  In order to coun-teract the deflective centrifugal force exerted on the rotating disc segments, the peripheral portion at the rear of the rotating disc is formed with an annular bulge having an annular channel therein for receiving mercury in an amount calculated to generate during the rotation of the bulging disc a counter centrifugal force equal to the deflecting centrifugal force exerted on the ro-tating grinding segments to thereby maintain the close tolerance spacing between the cooperating grinding segments.

Abstract: Abstract of the Disclosure An electrical connector housing has a first portion which surrounds a contact portion of the connector or terminal, a second portion which surrounds the ferrule portion of the terminal and a third portion which is intended to grip the insulation of an insulated wire when the ferrule is crimped to the core of the wire.  The first and second portions of the housing are made of a first plastics material such as a filled nylon material which is relatively rigid but which can withstand the compressive forces to be applied to the second portion when the terminal and core are crimped together in the housing.  The third portion is made of a different plastics material such as aromatic nylon which will not relax, as will the first material, after crimping of the third portion about the insulation of the wire.

Abstract: METHOD AND APPARATUS FOR ACOUSTICALLY SYNCHRONIZING             DROP FORMATION IN AN INK JET ARRAY                Abstract of the Disclosure An ink jet synchronization scheme, wherein the drop form-ation of respective streams in an ink jet array are synchronized acoustically by individual acoustic fiber inputs to each of the streams.  The acoustic fibers are attached to grooves adjacent each of the nozzles, with acoustic isolation being provided between the fiber and the nozzle substrate to prevent direct excitation of the substrate.  This prevents the occurrence of resonance within the nozzle plate.  Alternatively, acoustic isolation is achieved by mounting the synchronization structure separate from the nozzle plate.  For example, the acoustic fibers are attached to the charge electrode structure, or are attached to a support structure intermediate the nozzle plate and the charge electrode structure.  The acoustic energy inputs to the fibers are independently controlled as is required for certain printing schemes or are made identical as is normally the case.

Abstract: ABSTRACT            A bipolar transistor includes an emitter zone having two regions of different doping levels.  The more highly doped region is a surface-adjoining region located in the lower-doped region, extending only part-ally through the lower-doped region and laterally surrounding a central portion thereof.  The transistor also includes a surface-adjoining base contact zone which surrounds the emitter zone and is laterally spaced apart from the more highly-doped region of the emitter zone.           Additionally, a surface-adjoining conductive electrode is provided for contacting both the more highly-doped emitter region and the central portion of the less-highly doped region of the emitter zone.  The configuration results in a transistor having improved reverse breakdown characteris-tics.

Abstract: Blankenship 7 METHOD OF MAKING OPTICAL DEVICES                   Abstract of the Disclosure A method of making glass articles by the flame hydrolysis technique.  Particles of glass soot produced by flame hydrolysis are deposited on the outside surface of a mandrel to form a porous preform.  The soot particles closer to the mandrel have a refractive index greater than that of the soot disposed toward the outer surface of the preform.  The soot having the greater refractive index value has a viscosity lower than that of the soot having the lower refractive index value.  The mandrel is removed, and a vacuum pump is connected to the resultant aperture.  The soot preform is subjected to a high temperature whereby it is consolidated to form a dense glass blank.  The low pressure within the preform, the glass surface tension and the relative viscosities of the inner and outer portions of the preform cause the aperture to close during the consolidation process.  The resultant blank may be heated and drawn into a filament, or it may be sliced into optical windows,  lenses or the like.

Abstract: ABSTRACT           Apparatus for circular surgical stapling of hollow organs comprising an instrument and disposable cartridge.  The instrument comprises a housing with a throughbore in which a tube is received for reciprocation by means of a manually operable squeeze handle.  A rod reciprocates within the tube by means of a wing nut cooperating with a threaded part of the rod.  A two-part disposable cartridge assembly comprised of an anvil carrying part and a staple carrying part are detachably mounted on the rod and housing, respectively.  A key is provided to hold the housing and rod in rotational orientation.  Mutually coacting stops on the tube and rod determine the extent of reciprocation which is variable in dependence upon the position of the rod which in turn is dependent upon the juxtaposition of the anvil carrying part with the staple carrying part when the apparatus is closed on tissue preparatory to effecting a circular anastomoses.

Abstract: ABSTRACT OF THE DISCLOSURE      A circuit breaker electronic trip unit is equipped with a plurality of current transformers for sensing overcurrent and ground fault conditions in a distribution circuit. A ground fault signal voltage is applied to a differential amplifier together with an adjusted voltage establishing a desired ground fault signal pick-up level. The differential amplifier controls a variable duty cycle switch to establish charging versus discharging rates for a timing capacitor in accordance with ground fault signal amplitude. When the voltage across the capacitor exceeds a predetermined thres-hold, a thyristor is triggered to draw a safe level of energizing current through a trip coil. Secondary open circuited protection is provided for any of the current transformers disposed externally of the circuit breaker.

Abstract: ABSTRACT OF THE DISCLOSURE     Surge control systems are provided for compressors which supply air to a pneumatic load. A signal proportional to the pressure ratio of the outlet pressure to the inlet pressure plus a selected reference pressure is compared to a measured weight flow rate of air through the compressor to provide a vent valve command signal. If the measured pressure ratio plus the reference pressure ratio exceeds the measured flow rate, a surge condition may ensue.  The vent valve position command signal causes a venting valve to vent a portion of the air provided to the load,  which reduces the measured pressure ratio and increases weight flow rate. During normal operation of the compressor  the vent valve command signal is zero in ail values of weight flow rate.  A transient control channel is provided which is responsive to the rate of change of the measured pressure ratio and/or measured weight flow rate.

Abstract: Abstract Devices and processes, commonly used in controlling odors of human wastes in washrooms, are designed to attack the odor-carrying gasses in the air space of a room.  I this invention the emphasis is set, instead, on preventing odors from spreading into the air space of a room by deodor-izing these gasses at their source, i.e. the toilet bowl.  To accomplish this, a number of electrical resistors are fastened on the bottom of a toilet seat, to provide the heat required for changing the composition of these highly unstable odor-carrying gasses, before allowing them to enter into the air space of a washroom.
