Abstract: Dans les préoccupations pédagogiques actuelles, on cherche à promouvoir l'apprentissage des connaissances arithmétiques par des jeux qui travaillent sur les opérations de base.  Ces jeux utilisent des moyens assez compliqués et qui ne sont pas toujours conformes à la réalité mathématique. Dans la présente invention, on utilise un jeu structuré sous forme d'un tableau carré, divisé horizontalement et verticalement en cases carrées de même dimension et ayant une alternance claire et foncée.  Le nombre de cases sur chaque côté du tableau est un nombre impair et la case centrale dudit tableau est de même couleur que les cases pour les nombres et aussi identifiée d'une façon distincte.  Le jeu comporte également des jetons pour formera) une banque de nombres rationnellement choisis et compris entre 0 et 100, b) des signes opérationnels + (plus), - (moins), X (multiplication), - (division) et = (égal) et c) des signes de parenthèses( ), ayant leur signification conventionnelle attribuée dans les opérations arithmétiques;  Lesdits jetons doivent s'agencer sur le tableau pour former des équations arithmétiques.  En ce qui concerne la banque de nombres, la quantité des exemplaires pour chaque nombre entre 0 et 100 a été déterminée en fonction de la fréquence réelle de leur emploi mathématique.

Abstract: ABSTRACT OF THE DISCLOSURE In a method and an apparatus for automatically hemming a fabric piece, once a fabric means has been loaded onto the apparatus a series of steps are automatically performed by the apparatus to hem the bottom of the fabric means.  Additional automatic devices can also be provided to aid loading the fabric means and removing the hemmed product from the apparatus. The operator need only position, to a certain degree, the fabric piece on support means or cages, and thereafter a substantially automatic sequence of events occur.  The apparatus includes a substantial number of elements among which are the following:  a takeup device that subjects the fabric to the proper combination of tension and properly positions the leading edge of the fabric on the cloth plate of the sewing head, a series of uncurlers which when actuated ensure a flat edge, and a folder to create the hem; a puller which rotates the fabric around the supporting cages and a takeup device to develop the material hem while aligning the leading edge thereof in relation-ship of three tension zones; a logic system, which upon receipt of the proper inputs from a series of points, starts the actual sewing cycle.  As a result of the properly created zones of fabric tension, storing and carrying of the fabric is easily accomplished to achieve the desired results.  Thereafter a means which counts stitches determines when the hem has been completed, terminates the sewing step and actuates a means which remove the hemmed fabric from the apparatus.

Abstract: SYNC PATTERN ENCODING SYSTEM FOR RUN-LENGTH LIMITED CODES         Abstract of the Disclosure A system which employs a parallel to serial converter and a serial shift register encoder for encoding a multibyte sync pattern in a fixed rate variable word length run-length limited code wherein less than a single character of data is supplied to the encoder from the parallel to serial converter to encode the multibyte sync pattern.  The system provides for feeding a first portion of the encoded sync pattern back to the encoder through a serial decoder which provides a serial bit stream that is identical to the initial pattern pro-vided to the encoder.  Suitable control circuitry is employed to control the phasing of the end of the initial bit stream and the beginning of the decoded bit stream fed back to the encoder.  Once the feedback path is established, the total length of the encoded sync pattern is independent of the single character initially supplied to the encoder.

Abstract: COORINATE MEASURING MACHINE HAVING A FAILSAFE PROTECTION SYSTEM                          ABSTRACT      A coordinate measuring machine having an automatic failsafe  protection  system.   The  coordinate measuring machine includes a vertically mounted probe shaft which is preferably counterbalanced by an air  counterbalance system.  The automatic failsafe protection system insures that,  in  response  to  a  loss  of  air  pressure  (or  in response  to other possibly unsafe conditions),  the vertically-mounted, air-counterbalanced probe shaft will be  prevented  from  falling  down  uncontrollably.  The failsafe protection system includes a pair of members, with each member mounted  adjacent to and on opposite sides of the probe shaft and urged toward engagement with probe shaft by a spring.  Air under pressure from an air cylinder also acts upon the members to bias the members outwardly away from engagement with the shaft when normal (i.e.  safe)  operating conditions exist.   An unsafe operating condition causes  a decrease  in air pressure from the cylinder which allows the spring to bias the members into contact with the probe shaft to brake its descent by progressively engaging the shaft.  Additional springs also urge the members into contact with the probe shaft in response to an unsafe condition.    The present invention overcomes the limitations and undesirable  features  of  the  prior  art  devices  while providing a failsafe system which is relatively reliable and  inexpensive,  while  not  interfering  with  the functioning of a coordinate measuring machine in normal operation.
