Abstract: Pre-mixture forming swirler in gas turbine pre-mixed flame type low NO x combustor is improved so as to accelerate mixing of fuel and air and to prevent occurrence of flame stagnation and burning of component.         Three-dimensional swirler is constructed such that swirler vane (101a) is twisted from hub side thereof to tip side so that fitting angle (.beta.) of the tip side relative to fuel nozzle (102) center axis (C) is larger than that (.alpha.) of the hub side.  Thereby, while the angle (.alpha.) of the hub side is set smaller so that flame stagnation and burning of components resulted therefrom may be prevented from occurring, the angle (.beta.) of the tip side may be selected so that shearing flow necessary for appropriate mixing of fuel (F) and air (A) is obtained, thus favorable pre-mixing is done, life deterioration due to the burning etc. is prevented and combustion efficiency is enhanced.

Abstract: A dual clutch forward/reverse unit includes a pair of spring engaged clutch units and a pair of lifter pins, each pin operable to disengage a corresponding one of the clutches. An actuator mechanism for the forward/reverse unit includes a housing, a shaft rotatably mounted in the housing, and a hollow cylindrical sleeve rotatably mounted on the shaft. The shaft and the sleeve are operatively coupled to the lifter pins. The shaft has a pair of cam surfaces formed on an outer periphery thereof. The sleeve has a pair of openings through which the cam surfaces are exposed. A pair of lifters are pivotally supported in the housing. Each lifter has one side engaging a corresponding one of the lifter pins, and has another part engagable with one of the cam surfaces through a corresponding one of said openings. Each cam surface is thus operatively coupled to one of the lifter pins by a lifter. The sleeve is rotatable to a position wherein a wall of the sleeve acts to uncouple the lifters from the shaft so that the shaft can be rotated while both clutches are disengaged. The shaft is then rotatable to selectively engage one or the other of the clutches.

Abstract: The wireless system includes one or more payphones (12) from which users may initiate payphone calls.      A mobile switching center (16) connects telephone calls initiated from wireless payphones to external telephone systems (18) such as the publlic switch telephone network (PSTN). To meter charges incurred during the telephone call within an external system, the external system transmits periodic metering pulses (52, 54) to the mobile switching center. Each pulse is representative of a predetermined amount of money associated with the telephone call. The rate at which the periodic pulses are transmitted to the mobile switching center depends upon the current billing rate and may be affected by, for example, the time of day. Rather than the forwarding all of the metering pulses to the wireless payphone, therefore consuming a portion of the bandwidth available for wireless telephone calls, the mobile switching center (16) calculates a steady state billing rate from the metering pulses, then transmits only the steady state billing rate to the wireless payphone (12).

Abstract: A grenade machine gun or other weapon which employs superelevation of the barrel comprises a barrel unit and an aiming system mounted upon a support. The aiming system is mounted to the weapon and the support by a coupling unit. The aiming system comprises an imaging and display unit for displaying an image of a scene including a target, angle encoders for providing a signal representing displacement of the imaging unit in elevation relative to the support, and a control unit, e.g. a computer, for selecting either of two states for the coupling unit. The first state entrains the imaging unit to move with the barrel. The second state secures the imaging unit to the support and allows the barrel to move relative to both, i.e. during superelevation of the barrel. The coupling unit may comprise a first part connected to the weapon for rotation in elevation with the barrel unit and a second part connected to the imaging unit. The control unit may comprise a computer for superimposing upon the image an aiming reticle and a rangefinder reticle, the former representing an aiming point of the imaging unit and the latter representing an aiming point of the rangefinder, and may adjust the position of the aiming reticle in dependence upon the elevation signal, and stores coordinates for selected positions. The control computer may offset the displacement signal to displace the aiming reticle relative to the field of view in a direction opposite to the required superelevation angle.

Abstract: The present invention relates to a system and method for delivering emulsion explosive compositions into a borehole by means of an oversized diaphragm pump, which provides a relatively constant flow rate for the pumped emulsion composition thereby minimizing flow pulsations during delivery. More specifically, the system and method comprise an oversized diaphragm pump of significantly higher capacity than the intended flow rate of the emulsion composition, in combination with a water injection system that provides a lubricating annular stream of pressurized water between the pumped emulsion composition and the inner surface of a delivery hose for delivering the composition into a borehole. By minimizing flow pulsations, a safe, simple and easy to handle system and method for the delivery of emulsion compositions into boreholes are provided. Moreover, the diaphragm pump operates at a relatively low pressure which also enhances safety.
