Abstract: A silencing device for a vacuum cleaner.  In a primary embodiment,  the  silencing  device  includes  dampers  for absorbing operational vibration of a suction motor.   The operational noises of the suction motor are intercepted and suppressed by a middle case, a lower case, a bottom case and a top case.  The exhaust noises caused by exhaust air flow are repeatedly absorbed and suppressed by a plurality of exhaust ports.   The exhaust air flow is also dispersed so as to suppress the exhaust noises.  In the primary embodiment, the noises generated by both the suction motor and the exhaust air flow are effectively suppressed to desired low levels.  In a second embodiment,  the silencing device comprises a noise absorber for absorbing and suppressing both suction noises caused by suction air flow and operational noises of the suction motor.   The silencing device also has a cover for covering and  supporting  the  front  surface  of  the  noise absorber.  The back of the noise absorber is supported by a rear  supporter.    In  the  second  embodiment,  the  noises generated by both the suction motor and the suction air flow during suction of dirt-laden air by the suction motor are effectively suppressed to desired low levels.

Title: Two-way clutch
Inventor: ROBINSON ALLEN CLIFFORD
IPC: F16D41/067
Filed: 1994-07-20
Granted: 2004-01-20
Abstract: A two-way free-wheeling clutch is formed between a drive shaft and a driven shaft concentric with and encircling at least a portion of the drive shaft that is formed by axially extending substantially chord forming portions. The chord forming portions cooperate with circular bearings interposed between the portions and a circumferential surface of the encircling portion of the driven shaft to drive the driven shaft from the drive shaft. Drive of the driven shaft by the drive shaft is obtained by relatively positioning the bearings and the portions so the bearings are toward the radial extremities of their respective chord portions a driving wedge is formed with the inner circumferential surface of the driven shaft. When the portions and the bearings are shifted to relatively position the bearings closer to the centre of the chord forming portions i.e. minimum radial position on the chord free rotation of the driven shaft freewheeling of the driven shaft is permitted.  Circumferential movement of the circular bearings is impeded so that the relative positions of the circular bearings and their respective portions automatically change with a change in direction of rotation of the drive shaft or by simply stopping rotation of the drive shaft.

Abstract: A leak resistant, switching, double valve system consists of two sliding valve bodies in a valve housing with connecting lines. The two sliding valve bodies, which can be actuated independently of one another, are in contact in the closed position with valve seats in the valve housing, and are located at some distance one behind the other, forming a leak cavity between them. During the opening process, the first sliding valve body, before it leaves its valve seat, while simultaneously reducing the size of the leak cavity, can be placed in contact with the second sliding valve body, which is provided with a tubular extension which exits the valve housing in a sealed manner and connects the leak cavity to the environment of the valve system. With such a double valve system, the invention teaches that an optimal cleaning can be performed with minimal consumption of flushing agent, because the two sliding valve bodies can be moved independently of one another, each by a partial stroke opposite to the direction of the opening motion, into a flushing position, in which the sliding valve body is free from its valve seat and is in contact with a housing stop provided with flushing agent passages.

Abstract: A data correlated real time passive threat positioning system uses parallel estimated navigation filters (270). A threat data correlation process (204) accepts radar warning receiver track file data (206) and generates correlated threat data (208). A threat data management system (212) and a raw threat positioning system (214) accepts aircraft beading (226) and angle of arrival of the threat (229) to generate a threat status indicator (216) and a threat position measurement (224). Navigation filtering management apparatus (218) accepts the threat status indicators (216) and provide position filter controls (220). Parallel estimation navigation filters (270) use the position filter control (220) and the threat of position measurements (224) to generate estimated threat positions for a number of threats (241, 242, 243, 244, 245). The estimated threat positions (241, 242, 243, 244, 245) are updated and threat situation awareness is presented to the pilot in real-time. Elevation extraction apparatus (256) uses a terrain data base (272) and the threat estimated position (241, 242, 243, 244, 245) to predict the elevation of the threat. Threat data including latitude, longitude and elevation is provided to other systems.

Abstract: A dough cutting and packing apparatus for cutting a sheet of dough into dough pieces and transferring the dough pieces to containers. A cutting unit is defined by a plurality of cutting plates (14) having dough retaining openings. The sheet of dough is partially sheeted into the dough retaining openings by an initial compressor roll (13) which is spaced from an upper surface of the cutting plates. A terminal compressor roll (30) contacts the upper surface of the cutting plates, and acts to sheet a remaining portion of the dough sheet into the dough retaining openings to divide the dough sheet into a plurality of dough pieces retained in the openings. The initial compressor roll is driven at a peripheral rate of speed that exceeds an instantaneous linear rate of speed of the cutting unit. The terminal compressor roll is frictionally driven via contact with the cutting plates such that a peripheral rate of speed of the terminal compressor matches the linear rate of speed of the cutting unit. A packing mechanism transfers the dough pieces from the cutting unit to the containers as the containers are moved relative to the packing mechanism by a plurality of flighted augers.

IPC: G01S13/86
Filed: 1995-10-20
Granted: 1999-02-09
Abstract: A system (10) and method (20) that provides for all-weather precision guidance of conventional air-to-surface weapons. The system (10) and method employs a coherent monopulse radar (12) disposed on a launch platform (11) and a noncoherent passive (receive only) radar (14) disposed on the weapon (13). The synthetic aperture radar (12) generates a synthetic aperture radar monopulse map of an area around the target (15). The radar (12) is used designate the location of the target (15), and transmit a sequence of alternating sum and simultaneous azimuth and elevation difference patterns centered on the target (15). The weapon (13) includes a guidance system and seeker (14) that is responsive to guidance commands transmitted by the synthetic aperture radar (12). The guidance system and seeker (14) receives reflections of the alternating sum and combined azimuth and elevation difference pattern from the target (15), and the sum pulse is used by the weapon (13) to acquire and track the azimuth and elevation difference pattern null on the target (15) to fly an optimum trajectory to the target (15). One method for guiding a weapon (13) to a target comprises the following steps. A synthetic aperture radar (12) is used to generate (21) a SAR monopulse map of a target area and designate a target (15) therein. The weapon (13) is then launched (23) toward the target (15). The radar (12) is used to transmit (24) an interleaved sum and simultaneous azimuth and elevation difference pattern guidance pulse train at the target (15). The reflected interleaved sum and simultaneous azimuth and elevation difference pattern is received (25) from the target (15) at a seeker and guidance system (14) on the weapon (13). The sum pattern is used by the weapon (15) to lock (26) onto the converging null, and is used by the launch platform (11) to provide closed loop tracking of the target (15) during guidance illumination. After weapon null lock-on, steering commands are generated (27) to cause the weapon (13) to fly an optimum trajectory to the target (15).
