Title: Flue for heating stove or open fire - contains heat exchanger connected into central heating and/or water heating circuit
IPC: F28D21/00
Filed: 1984-11-16
Abstract: The heat exchanger is intended for recovering otherwise wasted heat from the flue gas of a heating stove or open fire. It is connected (10,11) into the circuit of a central heating system and/or of a hot water storage vessel. The heat exchanger pref. comprises two vertical tubular elements, of which one (7) connects at its upper end to a feed line (10) and the other (8) at its lower end to a return line (11). - The elements are connected via a number of horizontal tubes (9) which may be curved in alternate directions in horizontal planes. A narrow vertical branch (12) may extend from the line (10) into the element (8) to minimise condensation from the flue gas when the heat exchanger is still cold.

Abstract: ABSTRACT OF THE DISCLOSURE       An improvement has been provided in the production of reduced iron pellets from a material consisting mainly of dust exhausted from metallurgical furnaces for iron steel production, such as, for example, blast furnaces, converters, hearth furnaces and electric furnaces, and/or a mixture thereof, by the grate-kiln system for firing.          The procedure involves  the use of a travelling grate, and a rotary kiln.  Hot exhaust gases from the rotary kiln are first passed through a hardening zone and then through a preheating zone first to harden and then to preheat green pellets moving therein.  The exhaust gases are then intro-duced into a first dust collector, where dust of a high zinc content is collected from the exhaust gases, so that the exhaust gases are substantially completely free of zinc values.  The exhaust gases so purified are then passed through a drying zone to dry green pellets moving therein.          The exhaust gases are then introduced into a second dust collector, where dust is further collected from the exhaust gases.  The exhaust gases are discharged out of a stack to open air.  When the temperature of the exhaust gases which have passed the first dust collector is not high enough to be useful as a heat source for drying green pel-lets moving in the  drying zone, the temperature of gases for drying is raised as follows.  Hot gases, which are separately produced, e.g., by a fuel burner, are introduced into the drying zone.  The dust of high zinc content col-lected by the first dust collector is used as a material for zinc refining.

Abstract: ABSTRACT OF THE DISCLOSURE       Method and apparatus for  substantially simultaneously coating both surfaces of a web of indeterminate length. The web is fed in an upward direction  and passes between a pair of coating members. The coating   ?mposition is  dispensed from an elongated slot and each coating member arranged transverse to the direction of movement of the paper web. An excess amount of coating composition is dispensed so as to form a dam at the nip defined by the confronting surfaces of the web and the spreading  surface or lip of each coating member to assure uniform coating of the  surface.  The hydraulic pressure  provided by the liquid composition passing between the spreading surface of the coating member and the web contributes to the stability of the web and hence attenuates any fluttering of the web.      The spreading surfaces of the coating  members are  arranged in a staggered position  relative to the direction of movement of the web and preferably arranged to overlap one another so as to cause the path of the web in the region of the coating members to deviate from an imaginary straight line and hence to be pulled somewhat over each spreading surface which advantageously  compensates for any irregulari-ties in the spreading surfaces. The orientation of the coating  members and the dispensing outlets, as well as the rate at which coating composition is dispensed are all made independently adjustable to enhance regulation of the thickness and uniformity of the coating layers deposited upon the web.

Abstract: CENTRAL DICTATION SYSTEM                     ABSTRACT OF THE DISCLOSURE A central dictation system including a plurality of remote dictate stations, a plurality of record/reproduce stations and a plurality of transcribing stations operatively connected to respective ones of the record/ reproduce stations.  Any one of the remote dictate stations is capable of communicating with any one of the record/reproduce stations so as to execute a dictate and/or playback operation.  A transcribing operation is capable of being performed substantially independent of the dictate and/or playback operation and, therefore, may be performed simultaneously therewith.  Apparatus is provided for each record/reproduce station to provide an indication of the cumulative amount of record medium upon which dictated information has been recorded which is awaiting transcription.  This indication is affected in a first direction when dictation proceeds and is affected in an opposite direction when the dictated information is transcribed.  In another embodiment of the present invention, this indication is combined with an efficiency rating of a transcribing operator to produce a signal representing the effective capacity of the record/reproduce station to receive further dictated information.  This signal can be compared with similar signals associated with the remaining record/reproduce stations so as to determine which record/ reproduce station effectively has the greatest capacity for further recording and to promote the establishment of communication of a remote dicate station with that record/reproduce station.

Abstract: Subject :  CHANNEL SELECTION SYSTEM FOR A DISPLACED          SPECTRUM FREQUENCY SYNTHESIZER.     Abstract of the Disclosure A comparator-discriminator is provided, suitable for use with a phaselock control system of a frequency synthesizer, to permit automatic tuning of a variable oscillator to a selected frequency lying within a frequency band for which a phaselock may occur. This system permits the frequency of the variable oscillator to lock-on an arbitrary value in the range other than the preselected value, at which time the phaselock is bro-ken by an injected signal, thereby permitting the shifting of the oscillator frequency to another value lying closer to the selected frequency value.  Upon achievement of phaselock to the selected frequency, in a slightly more elaborate embodiment, the injected signal is inhibited and no further breaking of phase-lock can occur.  In operation of both the embodiments the compa-rator-discriminator provides a control signal in the sense of driving the variable oscillator towards the preselected fre-quency value, using a periodically actuated switch to connect the control signal to the oscillator control system.  A further embodiment of the system relates to a synthesizer with spectrum shift interpolation.  In two further embodiment of this system simplifications are made by which certain functions of channel selection and interpolation are combined.  One of these embodiments empemploys a phaselock oscillator as the basic frequency source for the channel selection system while the second embodiment employs a system of mixing and filtering.  The embodiments disclosed have the virtues of simplicity, low cost and enhanced reliability as well as a short channel selection time.
