Abstract: IMPROVED SUBMERGED COMBUSTION CALCINATION     Abstract of the Disclosure Gypsum is calcined by contacting it with the hot gases spewing out of a combustion tube submerged in the mass of gypsum.  The formation of dead-burned anhydrite is reduced by surrounding the combustion tube with a second tube called a draft tube.  Gypsum passing through the annulus between the tubes is heated by the hot gases and is ejected from the annulus to prevent repeated excursions into the hot gas zone at the muzzle of the combustion tube.

Abstract: ELECTRONIC POSTAGE METER HAVING NONVOLATILE                 MEMORY SELECTION MEANS     Abstract An electronic postage meter having an improved memory selection circuit is disclosed.  A custom memory map decoder circuit with resolution down to a single byte location is used to provide selection enabling signals to insure the selection of an appropriate device only when the addresses appropriate to that device are communicated.   In accordance with the invention, at least two nonvolatile memories are provided.     Writing to either of these nonvolatile memories is inhibited unless one and only one memory is selected.  The circuit also prevents the selection of either of the nonvolatile memories in the event that the write strobe signal to the memories is held active.

Abstract: ABSTRACT         An escapement mechanism for advancing a leading one of a row of gravity biased objects supported on a guide comprises a leading stop bracket and a trailing stop bracket pivotally mounted in fixed relation to one another and a piston and cylinder assembly, which pivots the two brackets.  The brackets are angularly displaced relative to one another such that at one time, one stop bracket is in the path of the objects to back them up and the other stop is out of the path of said objects.  The objects back up against the leading stop bracket and then the piston and cylinder assembly simultaneously pivots the trailing stop bracket into the path of the object immediately behind the leading object and pivots the leading stop bracket out of the path of the leading object to allow the leading object to advance by gravity beyond the escapement mechanism.  At a later time, the piston and cylinder assembly simultaneously pivots the leading stop bracket back into the path of the remaining objects and swings the trailing stop bracket out of the path of the remaining objects so that the remaining objects back up against the leading stop bracket.

Abstract: CATHETER ASSEMBLY                          Abstract A catheter assembly comprises a cannula having proximal  and distal  end portions and a longitudinal  duct  having an  initial  inner cross-section.  The duct increases in cross-section when at least a part of the distal end portion of the cannula is inserted into a body of a living subject and maintained in contact with the body, and/or when the duct is contacted by an aqueous liquid,  fox a period of time sufficient for an enlarged duct cross-section to form.  A hub has a passageway from a first to a second end thereof. The passageway has a cross-sectional area throughout at least substantially equal to 125% of the initial inner cross-section of the duct.  A proximal end portion of the cannula is attached to the first end of the hub with a passageway through the hub in flow communication with the duct in the proximal and portion of the cannula.  The attaching is such that the cross-section of the duct adjacent the proximal end portion, following formation of the enlarged duct  cross-section,  is  throughout  at  least substantially equal to the cross-sectional area of the passageway.  Increased flow is provided through the hub whereby advantage can be taken of the expansion of the duct.

Abstract: CMOS OPERATIONAL AMPLIFIER WITH  IMPROVED COMMON-MODE REJECTION     Abstract A fully differential CMOS operational amplifier (10) of the folded cascode type includes two similar signal current branches (32,34) connected in parallel between two supply voltage nodes (V+,V-). Each branch includes an N-type bias current transistor (42,54), a P-type cascode transistor (50,62), an N-type pull-down transistor (40,52), and a P-type current source transistor (48,60), all connected respectively in series between the drain of an N-type common mode suppression feedback transistor (44,56) and the drain of a P-type common mode suppression feedback transistor (46,58).  The N-type feedback transistor has its source connected to a negative supply voltage node.  The P-type feedback transistor has its source connected to a positive supply voltage node.  The gates of the feedback transistors of each branch are connected to the output node (36,38) at the drain of the cascode transistor. The gates of the other transistors are supplied with appropriate reference voltages (VB1,VB2,VB3,VB4). Second harmonic effects produced by the N-type and P-type feedback transistors of a branch cancel each other at the output node.  Also disclosed is a connection of the current source (20,22) of the differential input stage (12) to the drains of the N-type feedback transistors for reducing noise and device mismatch effects in the input stage.

Abstract: Low temp. gas, i.e. coolant gas from a nuclear reactor passes through a double section steam generator feeding a twin, high and low pressure turbine. A heat exchanger is placed close to the turbine group and used to reheat the feed water for the upstream section of the steam generator has its liquid inlet connected via a transition flask economiser to the downstream section, the heat for the water being derived from the intermediate turbine steam line. The lower part of teh economiser may contain a second heat exchanger group and cross feeds and bypass loops with control valves are used, together with a water degassing unit to regulate the system to optimum efficiency esp due to elimination of air from the boiler feed. The system has higher thermal efficiency than existing systems esp. those covered by CH 366056.

Abstract: Gas injection into a metal melt, accompanied if desired by powdered or solid treatment substances, is by way of a nozzle (14) inserted into the wall (12) of a melt-containing vessel (10). The nozzle bore (18) initially has a stopper (20) at its inner end and a delivery pipe (24) smaller than the bore (18) is movable therein. Before injection, the pipe (24) and bore (18) adjacent the stopper (20) are cooled by gas. By thrusting the pipe (24) against the stopper (20) while sufficient gas flow and pressure is maintained, the stopper is dislodged and the gas will enter the melt as a jet which leaves the pipe (24) at a velocity equalling or exceeding Mach 0.5. Melt enters the clearance between the pipe (24) and bore (18) but, due to the pre-injection cooling, rapidly freezes locking the pipe safely in the bore.
