Abstract: IMAGE OBSERVATION SYSTEM            Abstract:      Disclosed is an image observation system which employs a bellows expanded and contracted by fluid pressure to move an optical element, such as an image pick-up lens, within an image pick-up adapter.  The bellows, which is operatively associated with the optical element, is communicated with a manually operated fluid pressure drive unit by a fluid pressure transfer pipe.          Manipulating the drive unit forces a fluid into or withdraws a fluid from the bellows via the transfer pipe to expand or contract the bellows, thereby controlling the position or attitude of the optical element located at the end of an image fiber.

Abstract: "Arrangement for mixing a gas into a main flow of a second gas"     ABSTRACT OF THE DISCLOSURE        In an arrangement for mixing a first gas into a main flow of a second gas, comprising a main conduit for said main flow and a plurality of supply conduits for the first gas which open into said main conduit, the supply conduits are arranged as at least one set of three outlet openings.  This set consists of a first opening which opens into the main flow perpendicularly to the main conduit wall and two second openings which are arranged so as each to provide a lesser flow rate of the first gas than the first opening and are offset with respect to the first opening.  The three openings of the set thus direct the first gas into two contra-rotating circulatory movements, as viewed in the direction of the axis of the main conduit.  This mixing arrangement is applicable for example to mixing a hot gas into the gas obtained from an ore pellet drying bed and to mixing a hot gas into a water-laden gas from a desulphurization plant.

Abstract: "TWO PHASE FLOWMETER"                 ABSTRACT OF THE DISCLOSURE            The tubular flowmeter is capable of measuring two different physical parameters in a flowing mixture of liquid and gas (such as wet steam).  These measurements are such that they can be used to determine the individual gas and liquid flowrates.  The flowmeter comprises first means, such as an orifice plate or a twisted tape, for causing an accelerational or frictional pressure drop in the total flow.  Suitable means measure such pressure drop.  Downstream of the first means is positioned means for inducing rotational motion of the total flow, to cause the mixture to separate while remaining within the same conduit into discrete liquid and gas flows.  Such means may comprise a rib ex-tending helically along the inner surface of the flowmeter.  Means, such as a pitot-static tube assembly, measure a pressure head indicative of the velocity of the gas flow.  Downstream from this velocity measure-ment device, the two phases are permitted to mix freely again, all the time remaining within the same conduit.  The total flow pressure drop and gas flow velocity head measurements are used to compute or determine the individual gas and liquid flowrates.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for quenching steel rod in a high speed rolling mill is provided wherein a liquid coolant is preliminarily applied to the rod prior to its exiting from the mill finishing train in order to increase the column strength of the exiting rod by lowering the surface temperature thereof to less than about 950°C.          Thereafter, as the rod progresses through additional liquid cooling devices on the way to the mill laying head, tractive forces are applied to the rod.  The aforesaid increase in rod column strength acts in concert with the application of tractive force to insure that the rod has sufficient rigidity and forward momentum to pass from the finishing train through the liquid cooling devices and to and through the laying head.

Abstract: ABSTRACT OF THE DISCLOSURE         An asynchronous type optical modulation/ demodulation system of the type which transmits data by means of optical fibers is characterized by a trans-mitting circuit comprising a leading and falling edge detection circuit to generate pulses in response to the leading or falling edge of the electric input signal data.  A converter converts the output signal from the leading and falling edge detection circuit into pulses of positive or negative polarity in response to the electric input signal, and a light emitting element driving circuit inputs a signal of a predetermined level in response to a ready-for-sending signal and the posi-tive or negative polarity from the conversion means.  A light emitting element is charged by the light emitting element driving circuit and intensity-modulated with the input signal and an optical coupling means optically couples the output light from the light emitting element to the optical fibers and by a receiving circuit.  The receiving circuit comprises an optical coupling means to optically couple the fibers to the light emitting element and the light emitting element converts the light signal transmitted through the optical fibers into an electrical signal element.  A gain variable amplifying circuit amplifies the electric signal from the light receiving element to a predetermined level and an averaging circuit averages the output from the gain variable amplifying circuit.  A couple of binary circuits compare the averaged output from the averaging circuit with the output pulse from the gain variable amplifying circuit and output binary signal in response to the positive or negative polarity thereof respectively, and a flip-flop circuit in-puts the output from the binary circuits to the set and the reset terminals respectively and outputs the received data.
