Title: Vacuum forming process for articles having high forming stresses
Inventor: TAYLOR BENSON T JR
IPC: B29C35/02
Filed: 1987-08-27
Granted: 1991-04-23
Abstract: PATENT - 9D-HR-16745-Taylor et al VACUUM FORMING PROCESS FOR ARTICLES HAVING HIGH FORMING STRESSES        ABSTRACT OF THE INVENTION An improved vacuum forming process for forming a deep drawn plastic article with a flange in an area of high forming stresses wherein a mold mounted on a base forms the shape of the article.  A sheet of hot plastic material is placed over the mold and a vacuum is drawn to form the plastic sheet into the shape of the mold to form the article.  The improvement is forming a character in the mold portion that forms the flange in the area of the high forming stress, said character having dimensions such that properly heated plastic sheet material will be imprinted with a predetermined clarity during the molding operation.  A heated sheet of plastic material is placed over the mold and a vacuum is drawn to draw the plastic material around the mold including the mold portion that forms the flange in an area of high forming stresses.  The plastic material is then solidified and removed from the mold.  The flange is visually inspected to determine if the imprinted character has the predetermined clarity.  If it does, the plastic material was heated to the proper temperature for the molding operation.  If it does not, it means that the plastic material was not heated to the proper temperature and the area will be subjected to stress cracking and therefore the article is defective and should be discarded.

Title: Cross-connection network using time switch
Inventor: ISHIZAKI YASUTOSHI
IPC: H04Q11/04
Filed: 1987-09-30
Granted: 1990-12-27
Abstract: Abstract of the Disclosure:         In a cross-connection network, a plurality of asynchronous input digital signals can be cross-connected to a plurality of output lines by use of time switch.  The input digital signals are pulse stuffed at a common higher bit rate and are synchronized to one another by attaching extra bits.  The pulse stuffed signals are assigned into serial frames in a predetermined order by the multiplex technique and are interchanged from one to another by the time switch in the time division fashion.  The frame-interchanged signal is demultiplexed to reproduce the pulse-stuffed signals which are sent out to the respective output lines assigned to the frames after removing extra bits.          When the input digital signals are of higher order group, each of the higher order group digital signals is demultiplexed to lower order group signals which are pulse stuffed to be synchronized to the common higher bit rate.  The pulse stuffed lower order signals are rearranged by the multiplex technique to reform each of the high order group signal which is synchronized to one another.  The reformed higher order group signals are assigned in serial frames and are processed in the similar manner as described above.  The frame-interchanged signals are reversely processed to be separated, demultiplexed, destuffed, and multiplexed to reproduce the input signals as the output signals.

Title: Minimum height motor assembly using aluminum endshields
Inventor: LEWIS JOHN G
IPC: D06F37/20
Filed: 1989-02-09
Granted: 1992-05-05
Abstract: Abstract of the Disclosure A dynamoelectric machine in the form of an induction motor includes a rotor assembly and a stator assembly mounted between front and secured, cast aluminum endshields.  The endshields have axial and radial apertures formed in them to assist in motor cooling in the space-limited application environment of a clothes washing machine, for example.  A motor shaft extends through a journaled bearing in a bearing housing projecting from the front endshield.  A mounting plate is provided for mounting the motor in applicational use.  The shaft extends vertically downward through the mounting plate, to which the transmission of the washing machine also is mounted,so that a drive shaft also extends through the mounting plate.  A drive pulley is attached to the motor shaft and a driven pulley is attached to the transmission shaft.  The pulleys are maintained in planar alignment to permit belt transfer of power between the two and to minimize belt wear once the motor has been secured to the mounting plate by means of mounting ears which form a part of the first endshield of the motor.  The second endshield has an internal bearing housing design which provides a flush endshield surface facing upwards towards the bottom of the machine wash tub.  Because the first endshield mounts the motor, motor size, i.e. motor height can be varied to address differing machine load capacities by increasing the motor physical size, i.e. stator assembly stack height, between the fixed-position front endshield and the rear endshield to the extent permitted by the overall space available between the flush surface rear endshield and the flat bottom of the wash tub.  The motor mounting arrangement also provides a two point mount, which is easily varied to permit belt replacement, while maintaining the alignment between the pulley on the motor shaft and the pulley on the transmission shaft fixed and inviolate during machine operation.

Abstract: DELAYED CACHE WRITE ENABLE CIRCUIT FOR A DUAL     ABSTRACT          In an 80386/82385 microcomputer system, the timing requirements placed on non-cache memory components by the 82385 are more stringent than the timing requirements placed on the non-cache memory components by the 80386.  The present invention operates on the 82385 cache write enable (CWE) signals, and delays those signals in the event of a read miss.  Delaying the CWE signals relaxes the timing requirements placed on non-cacne memory components and at the same time does not impact wait state parameters for read miss operations.
