Granted: 1998-06-16
Abstract: The present invention discloses a method for producing modified cellulose.  The method comprises inoculating a quantity of nutrient medium comprising a polysaccharide derivative with a cellulose-producing microorganism.  The inoculated medium is then aerobically incubated to facilitate the production of cellulose.  The step of substantially drying the cellulose may be added for certain products.  The substantially dried cellulose which results from this procedure is highly absorbent, tending to retain its absorbent properties during repeated wetting and drying, and is usable where such absorbency is desired.

Abstract: Abstract of the Disclosure A vacuum-formed fill sheet for water cool-ing towers is provided with structure for contact with adjacent sheets for maintaining proper spacing around a perimeter of the sheets as well as between interior cooling zones formed within the sheet.  Top marginal edge portions of the sheets are formed in a corrugated pattern,  with the peaks and valleys of adjacent sheets being  inclined in opposite direc-tions  in  order  to  maintain  sheet  spacing  while enabling the film flow of water thereover to cooling zones  below.    Honeycomb  structure  formed  along facing,  side edge portions of adjacent sheets also assists in maintenance of the requisite sheet spac-ing while functioning  to  smoothly  guide  the  air between adjacent fill packs in a horizontal direc-tion with a minimum of pressure loss.  The honeycomb structure as well as the corrugated sections elimi-nate stresses within the sheets that might otherwise cause warpage, sagging or bending of the latter.

Title: Transmission error protection for tdma digital channels

IPC: H03M13/00
Filed: 1989-09-11
Granted: 1993-10-19
Abstract: TRANSMISSION ERROR PROTECTION FOR TDMA DIGITAL CHANNELS            Abstract of the Disclosure There is provided a method of reducing the effects of transmission errors in a digital cellular mobile radio system in which R-S symbols are transmitted over a radio channel in two bursts, separated in time.  This technique provides sufficient R-S error protection to recover the data if one of the bursts is entirely erased due to channel errors.  With a TDMA channel format, speech data is sent in bursts over the radio channel.  Each transmission bursts contain only half of the R-S symbols for a given R-S code block.  The two bursts, comprising a complete R-S block, are separated in time so that a short Raleigh fade in the transmission channel is only likely to affect one of the bursts, allowing the data to be completely recovered from the unaffected burst.  In order to provide sufficient error correcting power for this purpose, the R-S algorithm assumes that the number of protection symbols is at least as large as the number of data symbols.  Information regarding the likelihood of correctly decoding each of the received radio symbols (e.g. di-bits in the case of 4-phase DPSK transmission) is used to predict those R-S symbols most likely to be in error.  Those that are found likely to be in error are marked as erased.  This technique improves the recovery rate of the speech information bits.                    - i -

Abstract: The invention relates to an electrode intended, for example, for electrocardiogram examinations, and capable of being held in position by suction. Vacuum conditions are created through a hose or tube (8), through which a measuring conductor (7) is drawn. The electrode comprises an inflexible backpiece (3), an intermediate component (2) made of an elastomeric material, and an electrode plate (1), preferably made of a silver-coated plastics. The intermediate component (2) includes a relatively inflexible sealing ring (9) which, in the operative state of the electrode, supports against the skin of a patient via a sealing lip (13) and against the opposing side of the backpiece (3). The electrode plate (1) is firmly connected to the backpiece, while the sealing ring carried by the intermediate component (2) is movable and can be readily sprung away from the backpiece (via resilient means 17). When no load is exerted on the lip-side of the ring and the ring is thus urged outwardly, a vacuum valve is closed automatically through the intermediate component (2), and is re-opened when the electrode is pressed against the surface of the skin, whereupon the electrode is held firmly by suction.
