Abstract: PHO.81-502                  19             21.12.81 "ABSTRACT": "Reproducing apparatus"     A reproducing apparatus (1) for information signals recorded on a record carrier (2) in the form of a tape comprises two rotatable reproducing heads (11, 12) for alternately reproducing the information signals and a position encoder (19) which supplies position pulses for determinging the rotary position of the reproducing heads. A common pre-amplifier (22) is connected to the reproducing heads (11, 12), which amplifier is followed by compensation circuits (30, 31) associated with the two reproducing heads for signal correction, the output signal supplied by the compensation circuit associated with the reproducing head which instantaneously co-operates with the record carrier being applied to a signal processing circuit (23) during the scanning period of the relevant reproducing head de-pending on the position pulses. Only one of the two compen-sation stages (30, 31) comprises an adjustable frequency-dependent network (38) for frequency-response correction and at least one of the two compensation stages comprises a further adjustable frequency-independent network (39) for amplitude correction. This enables -the frequency response and -the amplitude characteristics of the two reproducing heads (11, 12) to be adapted to each other (Fig, 1).

Abstract: BELT CONVEYOR FOR CONVEYING       GRANULAR MATERIAL Abstract of the Disclosure An improved belt conveyor for conveying granular materials, such as grain.  The conveyor comprises a pair of end sections which are connected together by a plurality of central sections to provide the con-veyor with the desired length.  An endless conveyor belt, having a plurality of intetrally molded cleats, is carried by a pair of drive rollers, each of which is journalled in one of the end sections.  The grain, or other granular material, is fed into a hopper at one of the end sections and is conveyed along the bottom surface of the conveyor sections by the cleats and is discharged through openings in the bottom surface to feed bins.  The central conveyor sections are tapered throughout their length so that adjacent ends of the sections can be telescoped together to conveniently vary the length of the conveyor and facilitate attach-ment of the conveyor sections.  The openings in the bottom surface of the conveyor sections can be closed off by manually movable closure plates to thereby vary the distribution pattern to various feed bins.

Abstract: ABSTRACT OF THE DISCLOSURE      There is disclosed a technique for tightening threaded fasteners in which values of offset torque, initial tension rate relative to angle advance, final tension rate relative to angle advance and other joint related factors are empirically determined by instrumenting a plurality of fasteners of the type ultimately to be tightened.  In one embodiment, torque and angle of advance are monitored during the tightening of production fasteners.          Calculations are conducted, while tightening, of the ratio of the torque and the torque rate of the fastener being tightened to determine the tension prevailing in the bolt at a particular angle of advance.  By using the calculated tension value and the particular angle of advance, an instantaneous position of thread-ing advance on the tension-angle curve of the fasteners is established.  From this instantaneous position, it is determined how much greater angle of advance or how much torque is required to tighten the fasteners to a final desired tension value.  The same technique is also used merely to monitor tightening which is terminated by a different tightening strategy.  In another embodiment, analog devices are utilized to convert sensed values of torque and the rate of threading advance into parameters which control tool shut off.

Abstract: IN THE UNITED STATES PATENT AND TRADEMARK OFFICE            Inventor  :  E. RUSSELL SPRAGUE          Title     :  TAMPON APPLICATOR           Abstract of the Disclosure A tampon applicator of the telescoping tube type including an  ejector tube adapted to store a tampon in its distal end, a plurality of fingers formed in said distal end, an outer tube slip fit over the ejector tube, directionally-locking inward projections fixed within the distal end of said outer tube so as to pass between said fingers and engage a tampon carried therein thus securing the latter relative to said outer tube while permitting only distal expulsion therefrom.  Said applicator charged with a tampon is packaged and stored in a telescopically collapsed position.  It is activated for use by partial withdrawal of the ejector tube from the outer tube until the fingers of the ejector tube pass beyond the tampon and catch behind the proximal end of said tampon.  The applicator is then used in the usual manner by telescopically collapsing the ejector tube into the outer tube, whereby the ejector tube serves as a plunger bearing against the proximal end of the tampon to expel the latter.        Said outer tube preferably has inwardly curving protective petal sections at its distal end which form a rounded tip for facilitating insertion yet yieldably pass the tampon therethrough during the ejection step.

Abstract: PROCESS FOR REMOVAL OF HYDROGEN OXIDES AND SULFUR          OXIDES FROM WASTE GASES.            ABSTRACT.            A process for removal of nitrogen oxides and sulfur oxides from waste gases by contacting the waste gases with a particulate material comprising an alkaline earth based absorbent for sulfur oxides. Essential features are a reaction temperature of 85-145°C, a maximum value of 3 for the ratio of nitrogen oxides to sulfur oxides,and the presence of oxygen and moisture.          In its preferred form the process comprises a spray drying-absorption reaction followed by particle separa-tion in a bag house. Removal efficiency is improved by the presence of minor amounts of sodium sulfite together with the alkaline earth based absorbent. Also a special conveyance of material may be applied to improve efficiency.

Abstract: ABSTRACT OF THE DISCLOSURE    A  miniaturized  card  unit, resembling  a  standard credit card, incorporates solid state counter, a multi-plexer means,  and a small battery.  The counter may be incremented or decremented in accordance with a direc-tion control signal. A multiplexer in the card unit is releasably engageable with the demultiplexer provided in a card reader unit. Control signals, simultaneously app-lied to the multiplexer and demultiplexer transfer the count stored in the card unit to decoder driver circuits which drive a display for visually displaying the deci-mal count stored in the card. A logical circuit monitors selected segments of the display to enable operation of the device controlled by the card reader unit so long as the card inserted therein contains a non-zero count. The logical  circuit  prevents  operation of the device upon the occurrence of a zero count as well as the absence of a card unit. A relatively low frequency clock is utiliz-ed to control the illumination of the card reader dis-play  as  well  as  the  generation  of  the  multiplexing signals. Signals representative of the device usage are applied to the card unit counter for decrementing the count. A new count is introduced into the card unit by insertion into a  card programmer unit having settable thumbwheel  switches  for  setting  a  down  counter.  The presence of a card unit and the closure of a program switch causes simultaneous incrementing of the card unit counter and decrementing of the card program counter. When the card programmer unit counter is decremented to zero, incrementing of the card unit counter is automati-cally terminated. The card programmer unit display visu-ally displays the count in the card unit counter confirm-ing that the desired count has been placed in the card unit,  said display  incorporating demultiplexer,  driver and control circuits  similar to those provided in the card  reader  unit.  The  use  of  cascaded  gating  means prevents  false  count  pulses from being transferred to the card unit counter when the end count is reached.
