Title: Apparatus and method for insuring and controlling turbulent flow for cleaning ducts
Inventor: PLUMMER RAYMOND G
IPC: B05B15/02
Filed: 1993-06-03
Granted: 2004-04-06
Abstract: This invention concerns a system for insuring and accurately controlling the turbulent flow of a pressurized mixture of a gas (14) and a cleaning fluid (12, 10) for purging and cleaning ducts. The pressures of cleaning fluid (12, 10) and the gas (14) are continuously sensed and transduced into electrical signals for controlling valves for the pressurized gas (14) to maintain and insure its pressure at a predetermined amount relative to the pressure of said cleaning fluid (12, 10) so that when the gas (14) and fluid are mixed in a turbulator (20), turbulent flow is insured. The improvements of this circuit include a pressure sensor transducer (52) for sensing the pressure of the input of the air (14) to the turbulator (20) and feeding it back to the main air pressure transducer (52) for accurately maintaining a predetermined ratio between the gas (14) and cleaning fluid (12, 10) pressures within less than about 1 psi in at least pressures of 150 psi.

Abstract: A ball lock assembly having a cutting head (22) and a locking component (24) including a lock rod (94) carrying at least one locking member (105). A positioning assembly (50) operatively connects to the lock rod so that one can move the lock rod be-tween a locked position and an unlocked position. In the locked position the locking member engages the cutting head to hold the cutting head to the locking component. In the unlocked position the locking member does not engage the cutting head so that the cutting head is not held to the locking component.

Abstract: A system for reducing receiver power consumption in communication system having a transmitter (141) and one or more receivers (146) schedules periodic, message in "slot". Each receiver is assigned a slot during which monitors the transmission. The transmitter (141) transmits messages to the receiver only during the assigned slots. The receiver is in an "active state" during its assigned slot. During the "inactive sate", which is the time period between successive occurrences of its assigned slot, the receiver may perform any action not requiring coordination with transmitter. At a time during the inactive state shortly before the assigned slot, the receiver applies power to these components and performs initialization. Such initialization may include reacquiring a pilot channel signal to which the receiver may synchronize itself if its timing signal have drifted out of synchronization with those of the transmitter during the preceding inactive state.

Abstract: The apparatus has a distributor (11) with a straight conveying section (12), on which the N bundles of notes originating from a stack of sheets of notes are advanced one behind the other up to N predetermined bundle positions. Fitted underneath the conveying section (12), having an adjustable base (13), are N magazines in the form of vertical compartments which are located vertically underneath the bundle positions. Once all N bundle positions on the conveying section (12) are occupied by bundles, the base (13) is swung down, so that all N bundles can drop simultaneously into the N magazine compartments. After closing of the base, the next N bundles pass on the conveying section (12) into their bundle positions and, after opening of the base, can drop into the magazines as the second layer. Once packs with a predetermined number of bundles of notes lying one above the other have formed in these magazines, these packs are pushed by means of slides (16) out of the magazines (15) onto a transporting section (17), fitted next to the magazines, for the purpose of further processing.

Abstract: A functional radar warning receiver back-up generator (225) provides threat information in the total absence or partial absence of the radar warning receiver information (42, 208). Radar warning receiver information (42, 208) such as radar detection data and radar identification data is also generated by other systems such as the Pulsed Radar Jammer (36) and the Continuous Wave Radar Jammer (34). An on-board computer processes and presents the back-up information to the pilot as if the Radar Warning Receiver (12) was still operational. Voice (226) and video (224) functions of the Radar Warning Receiver (12) are also displayed and presented to the pilot.      Partial back-up (222) and full back-up (220) of the Radar Warning Receiver (12) are provided. A temporal data correlation algorithm (206), a radar emitter ID conversion algorithm (260), cross sensor correlation algorithm (248) and prioritization algorithm (244, 252) provide the back-up data.

Title: O-ring seal for rock bit bearings
Inventor: QUANTZ WAYNE C
IPC: E21B10/25
Filed: 1995-03-10
Granted: 1998-06-16
Abstract: An improved O-ring seal for rock bit bearings is formed from a resilient elastomeric composition comprising a multiplicity of low friction wear resistant particles distributed uniformly throughout the composition. The low friction wear resistant particles can have a rounded or non-rounded  configuration.   The  low  friction  wear resistant particles located near the surface of the O-ring are exposed through wear of the elastomeric component to form wear pads that contact adjacent rotating rock bit sealing surfaces.   The wear pads serve to reduce the break-off friction between the adjacent sealing surfaces and  minimize  the  occurrence  of  stick-slip,  thereby enhancing the service life of the O-ring seal and rock bit.
