Abstract: ABSTRACT OF THE DISCLOSURE         A pen recorder comprising a pen which is adapted to be placed in contact with a recording paper, a return spring which is capable of energizing a pen so that it is separated from the recording paper and a push-out means which pushes the pen so that it can be placed in contact with the recording paper. This push-out means includes a push-lever urging the pen towards the recording paper against a spring force larger than that of the return spring.  During the printing operation, this push-lever is separated from the roller, while during the waiting con-dition, it engages the roller. Accordingly, stabilized pen feed rate and contact pressure of pen can be realized during printing operation.

Abstract: ABSTRACT OF THE DISCLOSURE     A tire building drum is described as having a unique mechanism for controlling the radial movement of the bead lock segments which are designed to hold the tire bead rings firmly, in position, during the turn-up operation.  The mechanism includes an annular support member which is disposed concentrically around the longitudinal center axis of the drum adjacent opposing ends of the drum, and which has a number of raceways that are radially oriented in relation to said center axis.  The raceways are equally, angularly spaced about said axis and are designed to slidably receive a bead lock segment on which a cam roller is freely mounted for rotation.  The mechanism also includes an annular scroll member which is disposed concentrically around said axis in side-by-side parallel relation with each of the support members.  Each of the scroll members is rotatable about said axis and has a grooved trackway which spirals around said axis at least one and one-half times and which is designed to receive the cam rollers which project from the adjacent bead lock segments.  It can be appreciated that the segments will be forced to move in radial directions in response to rotation of the scroll members.          The mechanism further includes any suitable device, such as a pair of pistons reciprocative, in unison, in separate annular bores concentric about said axis, for rotating the scroll members, in unison, to simultaneously move the bead lock segments in equal radial distances to and from the center axis of the drum.

Abstract: A SILICON NITRIDE-CORDIERITE CERAMIC ARTICLE, AND PROCESS OF MANUFACTURE THEREOF     Abstract of the Disclosure A silicon nitride-cordierite article, and process for fabricating is described.  The silicon nitride imparts a high mechanical strength, and the cordierite contributes to a lower thermal conductivity making the composition especially useful for internal parts of a diesel engine.          The mechanical strength can be increased by crystallizing the continuous cordierite glassy phase of the article.          Crystallization of the continuous cordierite glassy phase is accomplished by the addition of a nucleating agent such as zirconium dioxide in the formulation and a subsequent reheating step after densification.

The code is used with the promotion to identify whether a customer has won any of the different prizes available.  In order to provide the needed variation and the completely random distribution of prizes needed for a fair game, each individual cup is separately encoded as it is being manufactured by a computer controlled printing station directly preceding a cup-forming machine.  All of the necessary information on the number or prizes, the frequency of occurrence of each prize and a program to randomize that frequency is placed in the computer software.  A scanner at the point of sale scans the code, signals whether the cup is a prize winner or not, and delivers a printed ticket notifying winners of their prizes and how to redeem them.

Abstract: ABSTRACT      A single-stage quadrupole mass analyzer is provided with a highly sensitive electron multiplier, a turbomolecular pump, and a mass correction lens placed between the quadrupole sensor unit and the turbomolecular pump.  These components are arranged and selected to provide a substantial increase in sensitivity permitting the direct analysis of organic compounds in the gas phase in the ppb and high ppt concentration range.  The placement of the mass correction lens and the area of its aperture has a pronounced effect on the detection limit, the optimum aperture area is a function of the mass of the molecules to be detected, and preferably an iris diaphram is used to permit manual or automatic adjustment of the aperture area to a predetermined optimum for each of the different substances to be detected.  Preferably the electron multiplier voltage is also variably selected and reset during the scanning of each fragment ion to optimize the signal-to-noise ratio of the electron multiplier.  The mass analyzer is sufficiently compact and economical to provide on-site analysis and the continuous monitoring or control of industrial processes.

Abstract: ABSTRACT OF THE INVENTION A  computer  system  includes  at  least  one  error detection  circuit  for  checking  data  bits  and  an associated check bit to verify that the data does not contain an  error. An  apparatus  for  verifying  the operation of the error detection circuit comprises a generator  unit  operatively  connected  to  said  data lines  for  receiving  data  bits,  for  outputting  a verification  signal  and  a  check  bit  signal.    The verification signal indicates the validity of the data bits during a read operation, and the check bit signal is generated during a write operation.  A gate element having an input terminal to receive at least one check bit  controls  at  least  one  input  to  the  generator unit.   A first control signal is transmitted to the generator unit thereby causing the check bit  signal generated by the generator unit to be valid or invalid in response to the first control signal.  Further, the check bit associated with the data is transmitted to the generator unit in response to a  second control signal.   The second control signal indicates the read operation  is  in  process  thereby  permitting  the generator  unit  to  perform  a  checking  operation independent  from the  first  control  signal,  thereby permitting  verification  of  the  error  detection circuit, the checking operation being the verification of the data during the read operation.
