Abstract: ABSTRACT     Figure 2 The present invention relates to a heat regenerator for use in heating an enclosure such as a furnace.     The heat regenerator 51 is detachable at one end from a burner B and at its other end from a reversing valve 58.  The regenerator 51 comprises two axially engaging portions 56 and 57, the front portion 56 comprising a cylindrical heat storage bed 59 and a surrounding annular layer 60 of a ceramic fibre insulation material.  The rear portion 57 comprises a cylindrical body of refractory material having a bore 61 forming a bottle-neck type passage tapering towards the valve 58.     The heat storage bed 59 comprises a monolithic refractory block through which a multiplicity of axially aligned gas-carrying channels 65 extends.  These channels 65 convey combustion products from the burner portion 52 to the regenerator portion 56 in one mode of operation where the bed is extracting heat from the products for storage.  In another mode of operation the channels 65 convey air from the portion 56 to the portion 52 so that the air can be heated by the stored heat now released from the bed.

Abstract: ABSTRACT A remotely controlled valve having an armature which is operated between its open and closed positions by means of a control drive.  The valve has a closure element which is displaceable by means of an axially movable spindle in a valve housing.  The spindle is axially driven by an adjustment drive through a spindle sleeve rotatably supported in the valve housing and having the spindle threadedly engaged therewith.  A transition bushing is rotatably secured to the spindle sleeve, a stroke-limiting member is secured to the spindle, and an intermediate cover and spring means are provided between the transition bushing and the spindle sleeve.  The transition bushing and the intermediate cover are slidable in the longitudinal direction of the spindle.  In the event of a malfunction of the drive control causing over-driving, the stroke-limiting member is forced against the transition bushing.  This causes the transition bushing and the intermediate cover to be displaced axially and the spring means are placed under load.  As a result, the rotating transition bushing rubs against the stroke-limiting member and the intermediate cover.  The frictional moments thus generated, together with the force of the springs, absorb the energy that has been introduced and the adjustment drive is braked gradually and gently.  The extent of the braking moment is selected on the basis of a suitable spring selection.  Thus, the maximum forces generated by inadvertent over-driving of the armature and drive assembly are reduced to a controllable level and valve failure is thereby avoided.

Abstract: ABSTRACT    IMPROVEMENTS IN OR RELATING TO CURRENT AMPLIFYING APPARATUS.    Two gate-coupled pairs (12,14; 16,18) of MOS transistors are configured in a compound current mirror (10,30) arrangement.  Each pair includes an input (12,16) and an output (14,18) transistor.  The output transistors are connected with their conduction paths in series between a current source and a reference voltage node (22).  Each of the input transistors is connected with its conduction path between the reference voltage node (22) and a separate current source (20,24), with both sources supplying the same input current.  One of the input transistors (12) has a conduction path width-to-length ratio one-fourth that of the other one (16).  This makes it possible to bias the output transistors with the minimum ON voltage for operation in the active region and thereby reduces power supply voltage overhead.

Abstract: P2486.01 METHOD AND APPARATUS FOR DRYING TUBULAR KNITTED FABRIC                       ABSTRACT OF THE DISCLOSURE The disclosure relates to techniques for high efficiency drying of wet-processed tubular knitted fabric. The wet tubular fabric is initially spread to flat form and then guided in a controlled manner over a so-called Mach nozzle, at which high velocity gaseous medium, usually steam, at speeds approaching the speed of sound and above, is discharged directly through the fabric, which is maintained in tension as it passes over the nozzle outlet. The thus treated tubular knitted fabric, now with a greatly reduced liquid content, is then immediately directed over a second spreader device, which distends the fabric widthwise to a predetermined, uniform width, to restore the fabric width lost during wet processing and during the relatively high tension nozzle treating operation. In this damp, geometrically stabilized condition, the fabric may be directed immediately into an otherwise conventional tensionless dryer for tubular knitted fabric, where the necessary final drying operations are completed. More typically, the fabric is loosely folded and then dried later. Significant production economies are realized pursuant to the invention, both in energy savings and labor savings, as well as reduction in capital equipment costs. The process also makes wet-on-wet foam processing relatively attractive for certain tubular knitted farics.

Abstract: ULTRASONIC TRANSDUCER FOR USE IN A CORROSIVE/ABRASIVE ENVIRONMENT               ABSTRACT OF THE DISCLOSURE         An ultrasonic transducer assembly capable of being operated in a corrosive and/or abrasive environment that might otherwise degrade transducer performance and/ or damage transducer related components.  The assembly includes an ultrasonic transducer of the type having a vibratile diaphragm supported at its periphery by a support housing and having the diaphragm center portion spaced a predetermined distance from a protective perfor-ated cover.  A channel is provided in the transducer between opposite sides of the vibratile diaphragm to avoid temperature induced pressure differentials between gases (air) present in the space immediately adjacent opposite diaphragm surfaces.  A plastic film is adhesive-ly attached to the outer surface of this diaphragm-protecting cover and the entire transducer is enclosed within an outer housing.  A flexible seal engages the plastic film and an outer housing surface.  With this arrangement the outer housing interior is divided into two isolated spacial volumes with one volume being in direct communication with the atmosphere and with the other volume (formed by the outer housing, plastic film and flexible seal) forming a chamber that completely isolates the entire ultrasonic transducer from its operating environment.  A tube couples the interior of the transducer containing chamber to a corrosive gas and foreign particle free environment at a remote protected location for the purpose of neutralizing any performance-degrading and/or protective film distorting pressure differentials between the two spacial volumes while avoiding direct contact between the transducer and/or related components and environmental components in the atmosphere potentially harmful to transducer performance, during such pressure neutralization.
