  • Patent number: 5360736
    Abstract: A live, attenuated varicella zoster virus vaccine is produced with enhanced yield of VZV. The new process makes mass production of a live VZV vaccine more practical.
    Type: Grant
    Filed: June 4, 1992
    Date of Patent: November 1, 1994
    Assignee: Merck & Co., Inc.

  • Patent number: 5278365
    Abstract: A wall switch latch includes a mounting plate having an enclosed slot directed therethrough and slidably receiving a fastener member directed into a wall plate permitting an abutment plate mounted to the mounting plate for abutment with an associated actuating lever bar of a wall switch mechanism. The abutment plate further includes a fluid dye saturated sponge arranged to mark the lever bar of the switch upon contact therewith.

  • Patent number: 5027376
    Abstract: Disclosed is a data compressing modem for connection to a decompressing modem over communication lines. The compressing modem receives an input data stream, and each character in the data stream is recodified with a compressed character code, the length of which is dependent on the frequency of the character in the data stream. A frequency table is maintained so that changes in the relative frequency of characters in the data stream will be recognized by the compressing modem and the compressed character codes representing such characters will be exchanged accordingly. A decompressing modem, which is connected over communication lines to the compressing modem, processes the compressed character code in a reverse order from the manner in which the compresing modem processing the codes. The decompressing modem also maintains a relative frequency table and as the relative frequencies of the various characters change, the actual characters represented by the compression codes must also change.
