Abstract: When a caller making a collect call encounters a busy called party or one that does not answer after a prescribed time, the telephone network offers the caller the opportunity to store a voice message in a messaging system at no charge to the caller. After the caller stores a message, one or more attempts are made to establish a connection between the messaging system and the called party's telephone. This may be done by periodically alerting the called party's telephone when it is in an on-hook state. When the called party answers, e.g., by going off-hook, the messaging system informs the called party that a collect voice message awaits him and asks if he is willing to pay to receive same. If the called partysignals that he is willing to pay to receive the voice message, the messaging system plays the stored voice message from the collect caller and signals the telephonenetwork to charge the account of the called party for supplying the message. If the called party signals that he is unwilling to pay to receive the voice message, the message is not delivered.

Abstract: A motor-vehicle door latch has a latching element movable between a latched position and an unlatched position, and a locking pawl engageable with the element and displaceable between a locked position retaining it in the latched position and an unlocked position allowing it to move into the unlatched position. Power actuation is effected by a planetary-gear drive including a reversible electric motor, a sun gear rotatable by the motor about the planetary axis, at least one planet gear meshing with the sun gear, a planet carrier carrying the planet gear, and a ring gear meshing with the planet gear. An actuating lever is displaceable by a door handle for movement of the locking pawl between the locked and unlocked positions. A coupling element is displaceable by a locking lever between a coupling position wherein it connects the locking pawl with the actuating lever for joint movement from the unlocked to the locked position, and a decoupling position wherein it permits the locking lever to move between its locked and unlocked positions independent of the locking pawl. The locking lever is movable by a manually operable locking element and the planet carrier. This door latch permits manual locking and unlocking of the latch in the antitheft-off condition without having to move the electric motor. An antitheft element is displaceable by the sun gear between an antitheft-on position wherein it maintains the coupling element in the decoupling position and an antitheft-off position wherein it permits movement of the coupling element between the coupling and decoupling positions. An arresting element selectively locks the plane carrier when the antitheft element is in the antitheft-on position.

Title: Liquid pressure amplification with bypass
Inventor: HYDE ROBERT E
IPC: F25B40/02
Filed: 1994-11-15
Granted: 2007-04-10
Abstract: Liquid pressure amplification with Bypass is used in an air-conditioning or refrigeration system which includes a compressor, a condenser, a pump, an expansion valve, and an evaporator, interconnected by conduits in a closed refrigerant loop. A first conduit coupling an outlet of the compressor to an inlet to the condenser. A centrifugal pump is coupled to the condenser (or receiver) outlet for boosting the pressure of the condensed liquid refrigerant by a substantially constant increment. A second conduit transmits a first portion of the condensed liquid refrigerant from outlet of the pump through the expansion valve into the evaporator to effect cooling. A third conduit transmits a second portion of the condensed liquid refrigerant from the pump outlet into the condenser inlet, which cools the superheated vapor refrigerant entering the condenser, reducing head pressure. A bypass having a valve around is provided to direct refrigerant around the pump in the event the pump is idled while the compressor remains in operation.

Abstract: A gas turbine fuel nozzle (11) and method of fuel flow provide resistance to coking of the fuel by means of a multiple passage heat transfer cooling circuit. Fuel streams to primary and secondary sprays of pilot (13) and main (15) nozzle tips are arranged to transfer heat between the pilot primary fuel stream and each of the main secondary fuel stream and the pilot secondary fuel stream. This protects the fuel in the streams from coking during both low flow, lower engine heat conditions and high flow, high engine heat conditions. This nozzle and flow can protect engines with both single tip and dual tip nozzles.

Granted: 2008-07-08
Abstract: An angiographic injector system (10) includes a motor driven pump (18) which delivers radiographic contrast material to a catheter (30) at a variable flow rate which is interactively controlled by a user. Operation of the pump (18) is controlled by the user, through a user actuated remote control (14). The angiographic system (10) also includes a manifold (26) and a valve which selectively connects either a syringe pump (18) or a low pressure system (38) to a catheter (30) which is inserted into a patient. The valve is normally biased to a state which connects the low pressure system (38) to the catheter (30) for pressure monitoring, saline flushing, or aspirating functions. When an injection is to be made, the valve automatically switches so that the low pressure system (38) is disconnected and not exposed to high pressure, while the syringe pump (18) is connected through the manifold (26) to the catheter (30).
