Title: A GSM-DCS dual-band transmit-receive switch for a mobile telephone
Inventor: JEUNET OLIVIER
IPC: H04B1/48
Filed: 2002-03-19
Abstract: Receive-transmit switches 1,2 for two bands are coupled by a diplexer 3 to an antenna 4. In switch 1, PIN diodes D1 and D2 are rendered conductive by a positive signal at control terminal SW1 to couple the transmit port EM1 to the diplexer and to isolate the receive port RE1. When the signal at terminal SW1 is removed, the transmit port EM1 is isolated and the receiver port RE1 is coupled to the diplexer via quarter-wave section Q1. The signal at terminal SW4 acts correspondingly on switch 2. To improve the isolation of receiver port RE1 when transmitter port EM2 is active, a positive signal at terminal SW4 activates diode D2 in switch 1 as well as the diodes D3 and D4 in switch 2. Terminal SW1 acts analogously on D4. The diodes DA prevent current flowing from one control port to the other.

Title: Vibration reduction apparatus for a power tool
Inventor: STIRM MICHAEL
IPC: B25D17/24
Filed: 2003-11-04
Abstract: A power hammer having a handle 302 mounted to a housing 312 wherein the handle is capable of limited movement relative to the housing. Hollow axle 316, is attached to the housing and rotates relative thereto between a first and second position and is biased towards the first position by a torsional spring 344 which extends within the axel. Arms 326a and 326b are fixed relative to the axle such that rotation of the axle causes rotation of the arms. Connectors 330a and 330b are slidably mounted within guides 332a and 332b and are respectively connected at one end to arms 326a and 326b and at the other end to the handle. In use, vibrations in the body of the power tool cause movement of one end of handle which causes movement of connector 330a and in turn of arm 326a. Movement of arm 326a causes rotation of the axle which therefore causes movement of the other arm 326b. This in turn causes connector 330b to slide within guide means 332b and move the other end of the handle. Thus the movement of one end of the handle is matched to the other end.

Title: Multiplying numbers in encryption systems
Inventor: SHANTZ SHEUELING CHANG
IPC: G06F7/38
Filed: 2004-06-21
Abstract: In response to executing a single arithmetic instruction, a first number is multiplied by a second number, and a partial result from a previously executed single arithmetic instruction is added implicitly to generate a result that represents the first number multiplied by the second number summed with the partial result from a previously executed single arithmetic instruction. The high order portion of the generated result is saved in an extended carry register as a next partial result for use with execution of a subsequent single arithmetic instruction. Execution of a single arithmetic instruction may instead generate a result that represents the first number multiplied by the second number summed with the partial result and also summed with a third number.

Title: Suppressing propeller noise in underwater sonar
Inventor: OKUNISHI AKIRA
IPC: G01S7/526
Filed: 2004-11-25
Abstract: An underwater sounding apparatus 5 comprises a transducer with a plurality of vibrating elements 6 for transmitting and receiving acoustic waves. Noise from a propeller 7 is removed from the received signals using a noise suppressor (fig 3). The noise suppressor utilises a reference signal which is derived either from one of the vibrating elements having a principal acoustic axis approximately in the propeller direction or from a reference beam formed by a group of the vibrating elements and directed in the propeller direction. Multiple reference signals may be used, for example to eliminate the influence of propeller noise which differs between the port and starboard sides of the vessel. A noise compensating signal is generated from the reference signal(s) by using adjustment factors. The adjustment factors may be determined from the received reference signals when transmission from the vibrating elements is interrupted but the propeller is kept turning. Alternatively the adjustment factors are calculated using a positional relationship between the propeller and each vibrating element.

Title: A system for separating an entrained immiscible liquid from a wet gas stream
Inventor: NATIONAL TANK COMPANY
IPC: B01D45/16
Filed: 2002-06-13
Abstract: A system for separating an entrained immiscible liquid from a wet gas stream comprises a vessel 10, having a wet gas inlet 14, a gas outlet 16 and a liquid outlet 18; a vortex tube 38 supported within the vessel; a hollow nose cone 50 positioned within the vortex tube; vortex generating vanes 64 disposed in an annular space surrounding the nose cone; a recycle port 84; and a circumferential opening 72. The vortex tube 38 is formed of two axially supported tubes wherein the space between the tubes defines the circumferential opening. The interior of the nose cone 56 communicates with recycled gases stripped off at the circumferential opening by a duct 88 and has an open end 52 having an increasing internal diameter 58. Wet gas enters the vortex tube and is caused to swirl by vanes 64. This causes the liquid in the gas to swirl around the inner surface off the tube and be stripped off with a portion of the gas, at the circumferential opening 74. The arrangement of the nose cone within the wet gas flow causes a venturi action which draws recycled gas into the nose cone through duct 88. There is only a single duct 88 which is streamlined to minimise resistance to the main wet gas flow.

Title: Gas injection device
Inventor: LIOU HUEI-TARNG
IPC: B01F35/60
Filed: 2005-08-31
Abstract: The subject invention is related to a gas injection device with back-flow leaking liquid discharge, comprising a chamber 10, a gas inlet conduit 20, a gas outlet conduit 30, and a liquid discharging conduit 40, wherein the gas outlet conduit and the liquid discharging conduit are provided with a check valve 60,80, respectively. When a gas is passed to the chamber through the gas inlet conduit, the check valve of the gas outlet conduit is open for the gas to be passed into a liquid and the check valve of the liquid discharging conduit is closed. While the gas has stopped injecting into the liquid, the check valve of the gas outlet is closed to prevent the liquid from back flow. The small amount of back-flow leaking liquid accumulated in the chamber can open the check valve of the liquid discharging conduit to discharge the leaking liquid from the chamber.
