Inventor: MCFETRIDGE GRANT T
IPC: H04N9/45
Filed: 1988-03-28
Abstract: The color burst of a first video signal is brought into a desired phase relationship with the color burst of a second video signal by generating a first number which is representative of the phase relationship between the burst of the second video signal and a calibration reference signal and gene­rating a second number which is representative of the phase relationship between the burst of the first video signal and the calibration reference signal. The second number is compared with the first number, and the phase of the burst of the first video signal is adjusted automatically in a manner such as to achieve a predetermined relation­ship between the second number and the first number.

Abstract: In a digital communication system including a central PABX system (12) coupled by a transmission line (20) to a remote telephone subsystem (14), a method for establishing synchronization between the PABX (12) and the telephone (16). The data format includes a message (24) transmitted from the PABX (12) to the telephone (16) during the first half of a frame and a response (26) transmitted from the telephone (16) to the PABX (12) during the second half of the frame. The synchronization method includes the steps of recognizing that synchronization has been lost, discontinuing transmission of responses (26) by placing the line driver (32) in a high impedance state while continuing transmission of message (24), and detecting a valid message (24) on the transmission line (20). The valid message (24) is detected by finding in sequence, a message stop bit (28), the stop bit remaining on the line for one half frame and a message start bit (27). When a valid message (24) is detected, transmission of responses (26) is resumed.

IPC: H03L7/18
Filed: 1988-11-24
Abstract: A phase-locked loop is formed by a series circuit of a counter, a register, an arithmetic unit, a low-pass filter, a PI-filter, and a voltage-controlled oscillator. The digital, internal clock signals generated by the oscillator are counted in a counter and are transferred into the register and stored as a current counter reading at points in time determined by time interval clock signals. For example, the time interval clock signals are acquired from reference clock signals by means of a divider and exhibit a lower frequency than the internal clock signals. A drive signal in digital form is determined in the arithmetic unit on the basis of the current counter reading, on the counter reading of the preceding evaluation interval, and on a rated value. This drive signal proceeds via a digital low-pass filter, PI-filter, and D/A converter to the control input of the oscillator, and controls the latter such that the internal clock signals coincide in phase with the reference clock signals.

IPC: C01F7/02
Filed: 1988-06-03
Abstract: Microcrystalline alpha-alumina based ceramic articles comprising at least 60% alumina by weight in which substantially all the alumina is in the alpha phase having a uniform grain structure comprising alpha alumina crystallites with an average crystallite size less than 0.5 micrometer and a density greater than 90% theoretical are disclosed. Ceramic articles particularly useful as high modulus refractory fibers, among other shaped bodies such as beads, flakes, coatings, and shaped or randomly-shaped abrasive particles, are produced from a unique sol-gel process wherein hydroxy iron polymers are utilized to nucleate the alpha alumina transformation. An inherent advantage of the unique process disclosed is the resulting fine grained microstructure which is essential if a ceramic article such as an alpha alumina fiber is to have reasonable strength.

Abstract: There is disclosed an optical ranging system adapted for use with widely varying return signal levels. Automatic signal level control is achieved in two parts, a passive optical part and an active electronic AGC part. The optical part is based on the coaxial arrangement of transmitting and receiving elements in which the shielded transmitting element is mounted in front of the receiving element, which includes a Fresnel lens which comprises a plastic casting. The electronic AGC portion of the system includes means for providing a voltage drive (with low internal impedance) for the final AGC transistor when it would tend to be slow, so little phase shift in the control results from changes in the signal levels. Thereby, the determination of distance (the ranging) by phase shift measurement is kept reliable as signal level changes. This optical ranging system is especially adapted for mounting on autonomously guided vehicles (robot carts), which are important for material handling and inventory control in manufacturing system in factory environments.

Abstract: This invention relates to abrasive grains, and, more particularly, abrasive grains having a particular shape and size. 
     Three basic technologies that can be employed in the production of shaped abrasive materials suitable for use as abrasive grains are fusion, sintering, and chemical ceramic. However, it is not known whether any particular shape or size of abrasive grains would provide enhanced properties with respect to abrading. 
     This invention provides abrasive grains having a shape such that the mean particle volume ratio thereof is less than about 0.8, and preferably ranges from about 0.3 to about 0.7. Typically, the grains have the shape of a thin platelet, the average thickness of which must be no greater than about 460 micrometers. 
     The abrasive grains of this invention can be used in coated abrasive products, bonded abrasive products, nonwoven abrasive products, and abrasive brushes. 
     The products made with the grains of this invention exhibit higher initial cut and higher total cut, along with lower grinding forces than do products having equivalent weight loadings of conventional abrasive grains.
