Abstract: ABSTRACT      A method for determining the iron-bonding capability of transferrine, consisting in adding to the sample being tested a reagent composed of a solution of a ferric salt absorbed onto a suspension of magnesium carbonate, centri-fuging the mixture so obtained and measuring the iron blocked by transferrine in the supernatant.  The method is preferably carried out by utilizing a particular compo-sition consisting of a single reagent composed of a su-spension of a solution of a ferric salt absorbed on ma-gnesium carbonate, possibly a medium capable of maintain-ing the pull between 8 and 9, if desired, so colorimetric reagent for the determination of iron.

Abstract: 15.                       Abstract Blow head supporting and moving mechanism of a glassware forming machine A blow head which defines an upper portion of a mould cavity in which glass parisons are blown to the shape of mould cavity is moved into and out of operative position by a combination of horizontal and vertical movement.  The vertical movement is brought about by a first piston and cylinder assembly (24, 26) and a second piston and cylinder assembly (38, 40) is operable, as the blow head approaches the parison, to oppose the action of the first piston and cylinder assembly (24, 26) thereby cushioning any impact between the blow head (4) and the parison.

Abstract: ABSTRACT OF THE DISCLOSURE        A slack adjuster for axially moved push rods is provided.          An axially extending rotating actuating shaft turns a helical, driving cam member that in turn axially displaces a non-rotating driven cam member.  The driving and driven helical cam members are located in a housing with the actuating shaft extending out of one end thereof and a threaded push rod extending out of the other end of the housing.  A helical return spring is positioned between the driven cam and the inner wall of the housing to bias the cam members together.  The push rod is held against rotation intern-ally of the housing by a flange whose periphery is frictionally engaged by the return spring.  A nut is threaded onto the rod and engaged by the driven cam member to transmit axial force to the push rod; and relative extension of the push rod from the cam members is accomplished by a one way spring brake acting on the nut and a disc clutch drive between the driving cam and nut.  Lost motion is provided to prevent rotation of the nut on the rod during normal push rod clearance,  and rotation of the nut on the push rod occurs when excessive push rod clearance occurs.

Abstract: AN IMPROVED GEAR PUMP OR MOTOR WITH A SHAFTLESS GEAR  Abstract of the Disclosure In a gear pump or motor having a housing and at least two intermeshing gears, one of the gears being fixed to a rotatable shaft and the other being a shaftless gear having a plurality of gear teeth rotatable on a film of fluid in close proximity to an interior surface of the housing, the improvement being a unique tooth profile on the shaftless gear.  Each gear tooth on the shaftless gear has a thick top land, preferably at least twice as thick as the top land on each gear tooth on the gear fixed to the rotatable shaft.  This particular intermeshing gear tooth config-uration increases the bearing surface of the shaftless gear on the film of fluid within the interior of the housing to better support the shaftless gear and thereby reduce frictional wear.

Abstract: METHOD AND APPARATUS FOR CHARGING A BATTERY     ABSTRACT OF THE DISCLOSURE         A battery is charged by repeatedly alternating between test and charge cycles.  During the test cycle, the dynamic voltage-current characteristic of the battery is obtained as a function of the charge condition of the battery.  During the charge cycle, a gradually varying voltage is supplied to the battery, substantially without controlling the current supplied thereto, for a predeter-mined time.  The rate at which this supplied voltage varies is related to the dynamic voltage-current characteristic obtained during the test cycle.  Alternating between test and charge cycles continues until the dynamic voltage-current characteristic last obtained is substantially identical to the preceding dynamic voltage-current characteristic, whereupon the charging of the battery is terminated.     -i-

Abstract: The present invention relates to a method and apparatus for cutting pieces of fabrics of uniform thickness and for stacking these pieces. The method generally includes arranging and maintaining a length of unrolled fabric on a cutting table which comprises a revolving cylinder which rotates so that the length of fabric is positioned to face a cutting instrument. The fabric is cut out according to one or more predetermined patterns when the cylinder stops rotating. Displacement of the cutting instrument over the circumference of a cylinder follows the generators of the cylinder during its motion. After the fabric is cut, the cylinder rotates to deposit the cutout pieces onto a fixed or mobile receiving/stacking table which is positioned under the cylinder. During such deposition, a new length of fabric is simultaneously arranged on the cylinder preparatory to being cut. Alternately, a conveyor belt can be used in lieu of the cylinder.

Abstract: ABSTRACT            There is disclosed a demodulating device for demodu-lating a composite PSK-PSK modulated wave comprising a 2n-phase (n being a positive integer) PSK modulated wave carrying a main signal and a 2-phase modulated wave carrying a subdata signal having a symbol rate slower than that of said main data signal.          The subdata signal includes a frame signal.  The device has a phase synchronizing demodulator for providing two orthogonally demodulated signals in response to the composite PSK-PSK modulated   wave.  The subdata signal is reproduced from the two orthogonally demodulated signals.  The main data is reproduced from the two orthogonally demodulated signals in response to the subdata signal.  The frame signal is extracted from the reproduced subdata signal and the phase locking-in state is discriminated in the phase synchronizing demodulator in response to the reproduced subdata signal and the extracted frame signal and provides a control signal.  The subdata signal components are removed from the reproduced main data in response to the control signal.  The invention removes the subdata signal components from the reproduced main data signal in a manner to permit the subdata signal to have high noise immunity.
