Title: Internet access system using voiceband modems and out-of-band transmission over local loop lines
Inventor: CRUDER OLIVER
IPC: H04M11/06
Filed: 1999-09-22
Granted: 2001-12-04
Abstract: Telephone service subscribers who are connected to a telephone network via local loop lines to local telephone switches are also connected to a data network without communication through the local telephone switches. The system has frequency translator devices for translating send and receive voiceband frequency signals used by voiceband data modems to different frequency bands above the voiceband used by the telephone network. The voiceband modems at the subscriber premises maintain a connection in the presence of transient signals caused by on-hook and off-hook activity of voiceband subscriber equipment. The system also has data network bridge equipment connected between the local loop lines and the data network for bidirectionally converting the translated voiceband frequency modem signals into digital data signals and bidirectionally relaying the digital data signals to the data network.  Internet access is made possible using conventional voiceband modems at the subscriber premises and using out-of-band transmission over the local loop lines so as to provide the Internet access without loading the local telephone switches and without preventing use of voice telephone service at a same time as Internet access is in progress.

Abstract: A spraying system having a plurality of spray nozzle assemblies mounted on a common liquid supply header. The spray nozzle assemblies each include a nozzle body fixed to the header and a spray tip secured to the body as an incident to rotation of the spray tip relative to the body. Each spray tip has an elongated discharge orifice adapted for emitting a flat spray pattern and is formed with radial gripping wings in aligned relation to the elongated discharge orifice which enable the user to know the orientation of the discharge orifice, and hence the orientation of the flat discharging spray pattern, prior to start up of a spray operation. The nozzle bodies further each are formed with at least one pair of indicator nibs, which when disposed in longitudinal alignment with the liquid supply header, automatically establishes an orientation of the spray tip elongated discharge orifice at a predetermined relative small angle to the axis of the header so as to avoid impingement of the discharging flat spray patterns of adjacent nozzle assemblies. An alternative embodiment of a spray tip has a slightly modified locking lug design for effecting mounting of the spray tip in the common body with the discharge orifice aligned with the axis of the fluid supply header. Further alternative embodiments include a spray nozzle with a swivel mounted adapter and quick disconnect spray tip, or with an adapter having a screw-in orifice defining insert for the particular spray application.

Abstract: A multi-carrier CDMA radio transmitting method replicates each information symbol and disposes thus-obtained information symbols along a frequency axis, multiplies the thus-obtained information symbols with a spreading code along the frequency axis, spreads the information symbols into components of a plurality of sub--carriers having different frequencies. The transmission rate of the information is changed by controlling the amount of information transmitted simultaneously by controlling the number of the information symbols to be used for spreading for the plurality of sub-carrier components for each user to which the information is to be transmitted.

Title: Automatic opening and closing device
Inventor: TSUGE NOBORU
IPC: E05F15/00
Filed: 1998-12-22
Granted: 2006-08-15
Abstract: An automatic opening-and-closing device can be obtained which can prevent a foreign object from being caught in by detecting the foreign object even if an opening/closing speed of a moving body changes or the foreign object is small. An automatic sliding door device 10 detects that there is an foreign object on a locus of sliding of a door panel 14 , by detecting a pushing reaction force when a pressure sensitive sensor 60 pushes the foreign object at the time of forward sliding of the door panel 14 slides forward. Hence, even if the sliding speed of the door panel 14 changes, or even if the foreign object is small, the foreign object can be detected to thereby prevent the foreign object from being caught in the door. Moreover, with the automatic sliding door device 10, a code 80 is passed through inside of the door panel 14 and connected to a lower end portion of the pressure sensitive sensor 60 via a circular hole 110 formed at a lower end portion of the door panel 14. Hence, the detection range on the upper end side of the door panel 14 can be made wider, and management of the code 80 at the time of assembly becomes easy.

Title: Belt tensioner and method of installing the same
Inventor: FRANKOWSKI MAREK
IPC: F16H7/12
Filed: 1999-09-15
Granted: 2007-08-28
Abstract: A belt tensioner for tensioning a belt for a motor vehicle comprises a pivot shaft (16), a pivoting structure (14) mounted for pivotal movement on the pivot shaft (16), and a pulley (12) mounted for rotation on the pivoting structure. A spring (18) biases the pivoting structure in a direction that moves the pulley mounted on the pivoting structure into tensioning engagement with the belt. A bolt (32) is constructed and arranged to mount the belt tensioner on the motor vehicle engine mount. The bolt (32) is constructed and arranged to be tightened to predetermined exent for installing the tensioner of the motor vehicle, the predetermined extent is the same extent to which the bolt is tightened during normal operation of the tensioner. A clamping structure (24, 36) applies a predetermined clamping force on the pivot shaft after the bolt is tightened to the predetermined extent. The predetermined clamping force is sufficiently large to maintain the pivot shaft in perpendicular relation to the engine mount and prevent tilting of the pivot shaft when the tensioner is moved into installed tensioning engagement with the belt, yet sufficiently small to permit manual movement of the pivot shaft relative to the mounting bolt for adjusting the amount of tension applied by the tensioner to the belt.

Abstract: A slip control article including a backing layer (21, 52) having a first surface (24) with an array of at least 15,5 upstanding stems (26, 56) per square centimeter and a second surface (25). At least a portion of the upstanding stems is an elastomeric material and the stems have an aspect ratio of at least 1.25. The first surface has a static coefficient of friction when dry of at least 0.6 and a static coefficient of friction when wet within 20 % of the static coefficient of friction when dry. The first surface has a peel strength and a tensile strength of substantially zero when engaged with another slip control article. The first surface has a relatively high shear strength when engaged with another slip control article. The high shear forces are due primarily to the frictional properties of the elastomeric materials, not a mechanical interlock of the stems, such as on a mechanical fastener.

Abstract: A process for increasing the tactile properties of a base web (38) without adversely effecting the strength of the web (38) is disclosed. In one embodiment, the process includes the steps of placing a base web (38) between a first moving conveyor (60) and a second moving conveyor (62). The conveyors are then wrapped around a shear-inducing roll (64) which creates shear forces that act upon the base web. The shear forces disrupt the web (38), increasing the softness and decreasing the stiffness of the web (38). The shear-inducing roll (64) typically has a relatively small diameter. In some applications, more than one shear-inducing roll (64) may be incorporated into the system.  Base webs (38) made according to the present invention have been found to have improved void-volume and fuzz-on-edge properties.
