Abstract: Abstract of the Disclosure A forced-air heating system with individual room or zone control of the temperature has an air distribution system that carries a forced flow of warm air from a furnace to outlets in each room.  Thermostats in each room are part of a control system and generate first and second control signals when the room temperature is below or above, respectively, a preselected value or values.  The first control signal opens the associated outlet and the second signal closes it.  The control system includes a central control device that fires and shuts down the furnace in response to the first and second signals from the room thermostats.  When at least a preselected number of rooms call for heat, the furnace starts.  When less than a preselected number of rooms signal that the associated outlet is open, the furnace shuts down.  In the preferred form, the system modulates the air flow in response to the number of rooms calling for heat.  The furnace is preferably an isothermal unit such as a heat pipe furnace or a miniature boiler that operates in conjunction with a fan-coil heat exchanger.  In either case, the furnace is preferably heated by a power burner with a variable firing rate responsive to the temperature of the circulating air at the furnace outlet.  In a modified form useful with existing conventional fixed rate forced air systems, certain outlets are permanently open and thermostatically controlled room outlets operating according to this inven-tion provide a secondary heating system for selected rooms.

Abstract: Abstract:        A vibration diagnosis method for a rotary machine is disclosed.  The presence or absence of a self-excited vibration is determined by checking if a rotating speed is in a rotating speed range which allows the occurrence of the self-excited vibration, if an amplitude of a frequency component corresponding to a first order critical speed is larger than a predetermined level, and if phases at characteristic points of vibration signals change among cycles.

Abstract: ABSTRACT     Device for the conveying of sheets from each of a plurality of sheet piles via a partially common conveyor track. This track extends in vertical direction along superposed stock holders. Adjacent to the sheet delivery side a driven roller is stationarily arranged above each pile. Each of these rollers can function both as suction roller for separating sheets from a pile and as friction roller for conveying sheets in the common track. For separating sheets from a pile, each pile can be brought by pneumatic means into short contact with a driven roller then functioning as a suction roller. For conveying sheets in the common track, each roller cooperates with a pressure roller. After a sheet in the common track has been gripped between a driven roller and a pressure roller, the sucting action of that driven roller is interrupted.

Abstract: A FRACTIONAL-DIVISION FREQUENCY        SYNTHESIZER FOR DIGITAL ANGLE-MODULATION     Abstract of the Disclosure In order to deliver an angle-modulated output signal as a function of digital information, the frequency synthesizer delivers an output frequency FS = (N + k)FR, where N is the integral part of a number N+k and FR is a reference frequency.  Provision is made for a variable oscillator, an oscillator control loop comprising in series a variable-rank divider prepositioned on the division rank N, a phase comparator for receiving the reference frequency and a summing device.  The synthesizer further comprises a phase accumulator for performing at the frequency FR modulo-M summation of a number G = k.M applied to its input.          The sum and carry outputs of the accumulator are coupled respectively to the summing device in order to deliver a signal for compensating the signal delivered by the phase comparator and to the divider for delivering a control signal at N+1 of the division rank. An adder having one out-put coupled to the input of the phase accumulator receives a constant number g on one input and a number dg which is representative of the digital information on another input.

Abstract: ABSTRACT OF THE DISCLOSURE:            In a method of introducing a starter bar head of a starter bar into the through-type mould of a horizontal continuous casting plant, the mould is removed from the continuous casting plant and placed vertical. Then the starter bar head separated from the starter bar is threaded into the mould and fixed in its position relative thereto. The mould, together with the starter bar head fixed to it, is installed into the plant. Subsequently, the starter bar head is coupled with the starter bar lying in the strand guide and then the fixation of the starter bar head is un-done. In an arrangement for carrying out this method, the starter bar head has a larger longitudinal extension than the aftercooling means. One end of it projects into the mould cavity and the other end is connectable with the starter bar outside of the aftercooling means. A fixing means for the starter bar head introduced into the mould is provided.

The fireproof adhesive material incorporates a predetermined quantity of sodium silicate in liquid form with which is mixed a quantity of surfactant/water solution sufficient to render the cured fireproof adhesive flexible and to provide for emulsification in the liquid state thereof.  The adhesive also includes a sufficient quantity of silicone water repellent to render the cured adhesive durable,  chemical resistant and water repellent.  Further, the adhesive material may include a liquid  stabilizer, plasticizer compound to enhance the flexibility of the cured adhesive.   For odor control,  a quantity of a malodor control agent may also be incorporated.      The fireproof adhesive material is prepared in the form of a liquid mixture wherein the ingredients of the mixture are basically incompatible and wherein the  ingredients  are introduced during continuous agitation in a particular order and after being placed in assembly, the incompatible liquid constituents are forced together by agitation for a sufficient period  of  time  to  render  the  mixture  substantially inseparable.  Upon curing, the adhesive mixture forms a solid, pliable or flexible mass having good surface adhesion.  When in the liquid form the mixture has a quality of efficient penetration and fiber encapsulation to render hazardous fibers nonviable and fireproof.
