Patent number: 4279465Abstract: An optical device for the simultaneous transmission and reception of optical data on the same optical waveguide. A transmission and receiving means at each end of the fiber optic cable permits simultaneous transmission. Each transmit/receive means comprises a pedestal supporting an emitter and photodetector. The emitter is mounted centrally of the inner surface of the pedestal at the focal point of a circular ellipsoidal reflector. The photodetector is also mounted centrally of the inner surface of the pedestal and placed forward of the emitter. In this manner the emitters and photodetectors at each end of the fiber optic cable can transmit and receive simultaneously or in sequence on the same optical waveguide.Type: GrantFiled: November 30, 1979Date of Patent: July 21, 1981Assignee: The Singer CompanyInventor: Mario M.

Patent number: 4246609Abstract: A switchable synchronizing-signal generator suitable for several television standards, information being supplied from a series arrangement of a clock pulse generator and frequency dividers to a synchronizing signal generator. The generator has a position for the N-standard which is a modified position for the M-standard, because the supply of pulses of double the line frequency to a divide-by-525 dividers is blocked during 50 line periods of each field period.Type: GrantFiled: November 14, 1978Date of Patent: January 20, 1981Assignee: U.S. Philips CorporationInventor: Nicolaas J.

Patent number: 4240679Abstract: An antifriction bearing having a ball bearing retainer positioned between an outer race and an inner race. A plurality of slidable wedges of the bearing conforming to the dimensions of the raceways are mounted in slots in the periphery of the retainer. In operation a centrifugal force is exerted on the retainer urging the wedges of the retainer to ride in the raceways. The wedges thus act as wipers maintaining a smooth oil film for the ball bearings regardless of the amount of lubricant in the raceways.Type: GrantFiled: January 25, 1979Date of Patent: December 23, 1980Assignee: The Singer CompanyInventor: Howard S. Schnoll

Patent number: 4216473Abstract: An attachment is provided for aircraft, and particularly for helicopters, for use in conjunction with a microwave interference pattern sensor (MIPS) system, to sense low velocities, for example, such as are encountered when the helicopter is in a hover mode. The attachment includes an antenna array which is separated from the MIPS antenna array, and which comprises two sets of transmitting and two pairs of receiving antenna horn apertures mounted in orthogonal relationship with one another, the transmitting apertures of each set being scanned in sequence to produce a moving energy pattern which is intercepted by the receiving antenna apertures of the attachment, even though the aircraft is stationary.Type: GrantFiled: November 16, 1978Date of Patent: August 5, 1980Assignee: The Singer CompanyInventors: Lester I. Goldfischer, Gus Stavis, Abraham Shrekenhamer

Patent number: 4202089Abstract: A machine for manufacturing high strength flexure hinges having use in accelerometers. A source of metal material is splat-cooled after it has been heated to a molten state. An induction heater heats the metal material to the molten state and the molten metal is rapidly cooled while being pressed between two water cooled wheels. The wheels are provided with indentations and protuberances on their surfaces to produce flexure hinges and strengthening beams. A chute is provided to catch the flexures as they leave the wheels preventing damage to them.Type: GrantFiled: June 2, 1978Date of Patent: May 13, 1980Assignee: The Singer CompanyInventor: Bo Hans G. Ljung

Patent number: 4173784Abstract: Conventional first and second Schuler tuned inertial platforms, that are physically displaced from each other by a predetermined distance, are employed in an inertial system to reduce navigation errors caused by the uncertainty in the earth's gravitational field. In addition to the two Schuler tuned platforms, a conventional velocity measuring instrument is employed to provide damping to the inertial system. The invention takes advantage of the fact that for a pair of ideal platforms if the relative velocity between them as displaced sensors can be measured with moderate accuracy then performance rivaling that obtainable with a gradiometer aided inertial platform can be achieved.Type: GrantFiled: August 29, 1977Date of Patent: November 6, 1979Assignee: The Singer CompanyInventors: William H. Heath, Jack Richman

Patent number: 4160974Abstract: A low cost system using passive radiometry or active radar for the detection of a target and providing discrimination between desired targets and false targets. The device may be mounted on a drone aircraft or other vehicle and comprises a detecting sensor having a fixed antenna system whose function is to detect the presence and direction to a target in airframe coordinates. The sensor provides means for generating a broad fan beam containing a plurality of closely spaced interference lobes spaced so as to encompass a predetermined target size. The interference lobes are continuously swept across the line of travel and the receiving circuitry provides means for detecting a desired target within the interference lobes. The system also provides a pre-programmed means, initiated by the target sensor, designed to aim the aircraft at the target and a target tracker or homing means having a fixed antenna directed along the heading axis of the drone aircraft and used to "home" the aircraft into the target.Type: GrantFiled: October 29, 1976Date of Patent: July 10, 1979Assignee: The Singer CompanyInventor: Gus Stavis

Patent number: 4155521Abstract: A gyro seeker which is capable of use in a cannon launched missile. The gyro seeker is enclosed in a housing mounted in the nose section of the missile. The platform of the gyro seeker supports an optical assembly, a detector, a gyro assembly, and a cryostat for cooling the detector. Means are provided on the outer gimbal of the platform for withstanding the extreme acceleration induced by cannon launching. The platform is torqueable along two axes by a plurality of pole pieces located around its base. A platform caging device is provided to cage the platform during transport and serves a dual function as a means to furnish spin-up gas to the gyro element and cooling gas to the cryostat.Type: GrantFiled: December 8, 1975Date of Patent: May 22, 1979Assignee: The Singer CompanyInventors: John L.

Patent number: 4153317Abstract: A method of forming a hard vacuum seal for use in a gas laser but not limited thereto. The method comprising the steps of polishing the surfaces to be joined together and then cleaning the surfaces with a plasma cleaner. Next, a force is applied to hold the surfaces in contact and then molten indium is applied onto the adjoining surface and allowed to cool in order to set the seal. In the method of forming the gas laser seal for fine alignment of the mirror surfaces, the seal is reheated, the mirrors realigned by sliding across the laser cavity while the laser is operative and the laser output is measured for maximum laser output. Then the seal is allowed to reset.Type: GrantFiled: December 2, 1977Date of Patent: May 8, 1979Assignee: The Singer CompanyInventors: Bo H. G. Ljung, James G. Koper
