  • Patent number: 5021726
    Abstract: Method and apparatus for driving an alternating-current motor. A sinusoidal supply AC voltage is rectified into a pulsating, unsmoothed DC voltage, with sinusoidal half waves and from this DC voltage an alternating-current motor voltage is produced by means of controllable polarity reversal. The pulse width of this alternating-voltage of the motor can be modulated. The polarity reversal takes place in accordance with the supply frequency in such a way that the AC voltage of the motor is essentially composed of the sinusoidal half waves of the pulsating DC voltage. For this purpose, the motor speed can be altered by changing the AC voltage of the motor with a constant timing frequency, lying outside the range of audibility, into pulse-width modulatable voltage pulses.

  • Patent number: 5020648
    Abstract: A light-weight, corrosion-resistant, multiple engaging ratchet assembly comprising few, easily manufactured parts for simplified operation of pawls and ratchet teeth in a free-wheel drive gear ratchet assembly. An outer wheel includes a cavity to receive an inner wheel with a pawl ring or integral pawls. The pawls ride over ratchet teeth protruding from a circumferential surface on the outer wheel when the inner wheel and the outer wheel rotate in opposite directions. Turning the inner wheel in a second direction the same as the outer wheel direction of rotation brings the pawls into engagement with the ratchet teeth causing the inner wheel to drive the outer wheel.

  • Patent number: 5020103
    Abstract: An adjustable height mounting pedestal for public or coin telephones comprises a tubular post having a plurality of knockouts at varying heights ranging from a drive-up curbside height to a standard handicap access height. A backboard mounting enclosure includes an opening therein that conforms to the peripheral configuration of the telephone for which the mounting is adapted. The configuration of the backboard extends about the telephone housing forward of the rear edge of the front housing of the telephone so as to protect the telephone from prying tools. The backboard and post include dividers for dividing the space within the backboard and post into electrically isolated channels for telephone wiring and for power wiring. Adjustable channels fit within selected knocked-out openings in the post when a particular height for the backboard is selected. The mounting channels and backboard are temporarily supported during assembly, to facilitate assembly by a single worker.

  • Patent number: 5018407
    Abstract: A lubricant filled drive assembly is disclosed having an insert to displace a portion of the required volume of lubricant. The insert is shaped so as to receive interchangeable or optional pieces of drive assembly equipment, and when certain pieces of equipment are not used, plugs are added to the assembly to occupy the empty space within the insert. By eliminating any unoccupied space, the plugs alleviate the need for additional lubricant which might otherwise be a cost of adding flexibility to the gear drive. The insert and plugs are preferably coated with a lubricant impermeable layer.

  • Patent number: 5018166
    Abstract: A data communications receiver for use in a modem. A fixed sample clock and a dominated tap tracking algorithm lock the local baud timing in the receiver to the baud timing in a remote transmitter. An interpolating filter provides a plurality of discrete delays. A filter control circuit inspects the tap coefficients of an adaptive equalizer to determine the location of and any movement of the dominant tap. The filter control circuit selects the rate of cycling through the discrete delays to compensate for any frequency difference between the local baud timing and the remote baud timing, and to prevent movement of the dominant tap. A baud detector circuit monitors the sample clock and the operating state of the filter control circuit to identify the end of a baud and detects and corrects for any frequency difference between the remote baud timing and the local baud timing by providing one additional sample or one less sample to the adaptive equalizer.

  • Patent number: 5017372
    Abstract: A method of producing a dry whey protein powder fortified with naturally occurring polyclonal antibody IgG to preselected infectious intestinal disease antigens, primarily diarrhea-causing enterotoxigenic Escherichia coli bacteria bearing colonization factor antigens (CFA) I or II and heat labile toxins. The product is made by first immunizing a pregnant ungulate, such as a cow, by administration of antigens of the preselected disease. After parturition the milk from the ungulate is collected and maintained in its natural state. The milk is subjected to a standard cheese-making process which produces coagulated casein and whey. The antibody IgG is carried into the whey, which is concentrated and dried. The resulting dried protein powder contains the antibody. The product may be administered orally to living beings, both humans and other animals, to prevent contraction of the preselected disease and to treat bodies exposed to the disease.

  • Patent number: 5017756
    Abstract: An improved electronic welding station is disclosed. The welding station provides for an improved arc striking capability by providing a higher arc striking voltage and a large arc striking current and, once the arc is struck, automatically switches over to preselected parameters for conducting the welding operation. Also disclosed are a method for preventing transistor failure due to loads which tend to cause a very large instantaneous current flow and an apparatus for protecting the driver circuit and the remaining output transistors in the event that one of the output transistors should suffer a collector-to-base short. The welding station also describes a method of operating the cooling fan at a speed commensurate with the cooling requirements and periodically reversing the voltage to the cooling fan so as to extend the operating lifetime of the fan brushes.

  • Patent number: 5015171
    Abstract: An improved flame holder based tunable pulse combustor, and a processing system employing same. The processing system is for thermal, chemical, and physical processes which employ natural acoustic modes in a processing chamber to enhance the processing. An acoustically resonant processing chamber is provided as the processing vessel. A frequency tunable pulse combustor comprising a flame holder is positioned to excite natural acoustic modes in the processing chamber. Material introduced into the processing chamber is thereby subjected to acoustic pulsations while the material is being processed. The acoustic excitations in the system result in improved moisture removal and particle heating. Also disclosed are various embodiments of frequency and amplitude tunable pulse combustors which may be employed to excite the natural acoustic modes in the processing chamber, including axially translatable acoustic decoupler and flame holder configurations.
