Title: Radio communication equipment for a mobile station and traffic channel hand-off method using the same
Inventor: YAMAO YASUSHI
IPC: H04W36/08
Filed: 1990-11-22
Granted: 1994-05-31
Abstract: In radio communication equipment for use in a mobile station, provision is made for selectively applying either one of the oscillation outputs of first and second local oscillators to a transmitting part and a receiving part by first and second RF switches, respectively.  In a traffic channel hand-off system for a mobile communication system in which each time the mobile station moves from a certain zone to another, its traffic channel is switched to another traffic channel of a different frequency, a control part responds to a traffic channel assigning signal from the current base station to allot an idle one of the local oscillators to the assigned channel, set the allotted local oscillator to an oscillation frequency corresponding to the assigned channel, and control the second RF switch, in an idle time of the receiving part in the current communication, to set the receiving part to the assigned channel for receiving a down link hand-off preparatory signal from a new base station.  Further, the control part controls the first RF switch, in an idle time of the transmitting part in the current communication, to set the transmitting part to the assigned channel for transmitting an up link hand-off preparatory signal to the new base station. These preparatory procedures are followed by controlling the first and second RF switches to supply the oscillation output of the allotted local oscillator to the transmitting part and the receiving part, thereby completing the traffic channel hand-off without momentarily interrupting the communication.

Abstract: A smooth resistance characteristic, a reduction in component cost, and high durability are achieved for a variable resistor card formed using thick-film silk screen deposition. An arcuate wiper track and radial extension areas are all formed of a resistance material deposited using silk screen techniques. Laser trimming of the extension areas provides a desired characteristic of resistance versus sweep angle for the variable resistor. The resistance characteristic is continuous and nonstepped, thereby avoiding the creation of spikes caused by small circuit breaks during sweeping movement of the wiper contact.

Abstract: SERVICE DISCONNECT AND METER STORAGE ADAPTER                   ABSTRACT OF THE DISCLOSURE           A service disconnect adapter mounted between a plug-in meter socket and a watthour meter.  The service disconnect adapter has blades mounted on a base which engage terminals in the socket.  Watthour blade receiving fingers are formed in the service disconnect adapter to receive and frictionally engage watthour meter blades.  The service disconnect adapter electrically isolates the socket load terminals from the watthour meter blades to disconnect the watthour meter from the load side terminals of the socket.  The blades are angularly offset from the watthour meter blade receiving fingers in the adapter to mount the watthour meter at an angle from its normal mounting position.  A pair of electrically conductive jumpers are mounted on and extend through the base in the adapter and are electrically connectible between the socket line terminals and the selected ones of the watthour meter contact blades to connect electric power to the watthour meter while the watthour meter load contact blades are disconnected from the socket load terminals.

Title: Hydroentangled polyolefin web
Inventor: SIMPSON PENNY C
IPC: D04H1/46
Filed: 1991-08-14
Granted: 2001-09-11
Abstract: A process is disclosed for hydroentangling continuous polyolefin filament fibers to form a fabric web.      The fibers are supported on a 60 to 150 mesh screen and passed under high pressure water jets operating at at least 2000 psi and providing a total impact energy of at least 0.7 MJ-N/Kg to entangle the fibers. Preferably, the hydroentangled web is thereafter passed under finer finishing water jets operating at a pressure of between 300 to 1200 psi to redistribute the fibers. If desired, a finish may be applied to the entangled web. The resulting hydroentangled web has considerably increased visual uniformity, opacity, softness, comfort, strength and barrier properties compared to prior art webs thereby making it particularly useful as a disposable industrial garment.
