Abstract: Improved runnability is obtained in the dryer section of a papermaking machine while high drying efficiency is maintained by wrapping a small portion of the pick-up roll from one dryer group to the next with the web support belt from the first dryer group, so that the web is safely transferred.  In addition, a configuration of cylinders in the drying section is described which ensures the web is held against the support belt when it travels from one of the drying cylinders to the following suction roll.  In this configuration, the distance between the periphery of the suction roll and the periphery of the delivering cylinder is smaller than the distance between the periphery of the suction roll and the periphery of a receiving cylinder.

Title: Aerial distress flare
Inventor: CAMERON ROBERT W
IPC: F41A19/58
Filed: 1991-02-21
Abstract: ABSTRACT    An emergency signalling device comprising an elongate shell to be fired into the air.  The shell encloses a combustible propellant charge, combustible material for generating a visible smoke trail, combustible material for generating a visible spark trail, at least one explosive charge for generating an audible report, a multiplicity of radar chaff particles, and an explosive ejection charge for distributing the radar chaff particles from the shell once the shell has been propelled beyond a predetermined altitude.  An ignitor wire is provided which is in contact with the propellant charge.  The shell is enclosed in a barrel for storage and launching. The barrel has an external thumbstop to prevent recoil from pushing the barrel back through the hand of the operator.  There is a bulkhead at the closed lower end of the barrel, on which are mounted electrical contacts connected to the ends of the ignitor wire.  A cap is threadably engaged with the lower end of the barrel, and has a battery therein which has contacts on an inner surface of the cap.  The end cap is manually tightened against the lower end of the barrel to briny the contacts into abutment with one another, igniting the propellant charge. The shell has stabilizer fins with flexible portions which are folded circumferentially between the shell and the barrel, and which are released and extend radially when the shell is launched.

IPC: H04L29/00
Filed: 1991-06-25
Abstract: METHOD AND APPARATUS FOR TRANSMISSION OF LOCAL AREA NETWORK SIGNALS OVER UNSHIELDED TWISTED PAIRS     ABSTRACT OF THE DISCLOSURE         Apparatus, and a related method for its opera-tion,  for transmitting binary data at high speed through unshielded twisted pairs of conductors intended for a much lower data speed and bandwidth. By using a combination of demultiplexing into multiple data chan-nels,  encoding the binary signals into a modified three-level duobinary code,  and filtering the signals before transmission, data rates as high as 125 megabits per second can be transmitted over four unshielded twisted pairs of conductors. Two illustrative forms of the invention are disclosed,  one of which uses two channels  for transmission over two twisted pairs in each direction of transmission. The other form of the invention uses four data channels,  to further reduce the transmitted bandwidth in each channel,  and four twisted pairs of conductors,  for transmission in both directions by means of hybrid circuits interconnecting the transmitter and receiver functions at each end of the channels.

Title: Azimuthal toroid array for resistivity logging system
Inventor: GIANZERO STANLEY C
IPC: G01V3/28
Filed: 1991-07-10
Abstract: ABSTRACT OF THE DISCLOSURE             This disclosure is directed to a set of coils which are installed on a MWD drill collar for use in a resistivity logging system. The drill collar is provided with upper and lower coil support rings. These are toroids which support individual coil segments, and are connected by suitable magnetic shorting bars. The coil segments and shorting bars inscribe a specified azimuthal extent. By connecting the outputs of the several coils through a combining circuit, the coils on a single coil form can be connected in series additive, or subtractive relationship. Through the use of two such coil forms with aligned coils on each, an aximuthally oriented window is thereby defined. Multiple windows are defined. By proper switching, the windows can be made operative so that there is an azimuthal orientation to the current flow pattern relative to the MWD resistivity logging tool.     HLS 89.093
