Abstract: Turbine pumps can include: an inlet port; a first discharge port; a body defining a flow path extending from the inlet port through a raceway to the discharge port; and a turbine impeller disposed in the raceway. In some pumps, the body further defines an channel providing a fluid connection between a raceway outlet and the discharge port. In some pumps, an outlet angle defined by the inlet port, an axis of the turbine, and the discharge port is between 30 and 180 degrees.

Abstract: A method (1000) for automatically opening a closeable communications device and a closeable communications device (100). The closeable communications device (100) has a housing having two biased housing portions (210,220) movably mounted to each other to allow relative movement of the two portions between a closed position and an opened position, the two biased housing portions (210,220) being biased to the opened position. There is an electrically operable latch (270) retaining the two biased housing portions (210,220) in the closed position and a radio frequency communications unit (102) is located in the housing. A processor (103) is located in the housing and is coupled to both the radio frequency communications unit (102) and the electrically operable latch (270).

Abstract: A three part housing wireless communications device (100) with a display housing portion (110) with a display screen (137) and a left ear housing portion (160), with a with a left speaker 161 and left ear mount 340, pivotally mounted to the display housing portion (110). There is a right ear housing portion (170), with a right ear mount (440) and a right speaker 171, pivotally mounted to the display housing portion (110). The three part housing wireless communications device (100) has a radio frequency communications unit mounted providing wireless communication with a communications network.

Abstract: A fire detection and suppression apparatus includes an interface device (10) adapted to be mounted to a support surface A. The device (10) has an outer body (12), and an inner plunger (20) movable within the outer body (12) upon the supply of a pressurized fluid to open discharge outlets (13, 23) for the release of the pressurized fluid from the device. The plunger (20) is biased by a spring (21), to return to a closed position so as to close the discharge outlets (13, 23). The pressurized fluid is sufficient to overcome the spring (21) which can close the discharge outlets (13, 23) when the pressure of fluid drops below the force of the spring (21).

Abstract: A lanyard support for a portable telecommunications device (1) comprises an integrated headset and device suspension system with neck lanyard (5) havings a microphone (8), an earbud speakerphone (7) and a tensionable attachment member (10) securable to a lanyard bail (3) on the device (1). The portable telecommunications device (1) is located in a pouch (2) with extension cords (16,17) extending between the lower part of the pouch and a respective side of the neck lanyard. The portable telecommunications device (1) is suspended from the neck of a wearer to permit handsfree operation while an antenna (9) of the device (1) is inclined outwardly away form an upright axis of a wearer's torso to improve antenna sensitivity.

Abstract: A foldable communication device (10) with a housing having two portions (11,12) pivotably mounted to each other to allow relative movement therebetween. This relative movement is about an axis (13) and enabled by mounting portion (11) to two mounts (14,15) of portion (12). Device (10) has a transceiver (17) housed in the housing, an alert transducer (18) associated with transceiver (17) to provide an audible alert at a predetermined volume when a communication call for device (10) is received by transceiver (17) and a controller (19) coupled to transducer (18). In response to the relative movement of portions (11,12), controller (19) reduces the volume of the audible alert without the communication call being answered.

Abstract: A concurrent component mounter (1) having storage hoppers (2) and a template (3) with component dispensing outlets (4). The mounter (1) also has communication passages (5) each providing communication between respective hoppers (2) and one of the dispensing outlets (4). Associated with each of the hoppers (2) is a component agitator (6). There is also a circuit board conveyor (22) and a circuit board fiducial detector (23) operatively coupled to a controller (24). Tracks (25,26) with associated drives (27,28) are operatively coupled to the controller (24) to effect movement of the template (3) along two axes (A,B).

Abstract: A remote meter reading system employing a plurality of multiplexers coupled between the telephone central office and remote interrogatable utility data sources. A number of lines are connected to a single data channel through a plurality of multiplexers. An interrogation signal source is connected to the multiplexer for sending controllable level interrogation signals to the data sources under the control of a microprocessor. The level of interrogation signal which produces a response from each different data source is stored. Upon failure to evoke a response from the highest level of interrogation signal causes that line to be recorded in memory as defective. The number of OFF-HOOK conditions encountered in a predetermined period is recorded and any excess of a predetermined value deleted as a line trouble condition. Signalling in the preferred embodiment is via pulse width modulated signals. In the alternate embodiment, dual tone signalling is employed.
