  • Patent number: 5423361
    Abstract: A bit with a fiber cutter for a rosser head debarking machine. The bit has a base for mounting the bit onto the rosser head. The striking edge of the bit is connected to the base and comes into contact with bark and removes the bark as the rosser head spins. The bit has at least one replaceable fiber cutter that includes a cutting edge that cuts through the bark or fiber within the bark as the rosser head spins. Preferably, the fiber cutter is disk-shaped and tapered away from the striking edge and cuts through the fiber in the bark in a perpendicular direction to the fiber. The cutter can be connected to the bit by a threaded bolt that is positioned through a hole in the middle of the cutter and into a threaded hole in the bit. The bit can have threaded holes on both sides to allow two cutters to be installed or for the bit to be rotated.

  • Patent number: 5386473
    Abstract: A passive circuit for decoding surround-sound signals using a transformer having center-tapped primary and secondary windings. The line level left and right signals are introduced into the primary winding, and the center tap of the primary supplies a left-plus-right center channel output. The secondary center tap is grounded, and the winding connections supply left-minus-right and right-minus-left surround outputs. The same circuit can be used for recording surround sound onto a two-channel (stereo) medium. A center microphone is connected to the center tap of the primary winding. Left and right surround microphones are connected to the secondary winding, which has its center tap grounded. The left and right recorder inputs are connected to the opposite sides of the primary winding.

  • Patent number: 5382779
    Abstract: A price verification method for retail stores using shelf pricing, and apparatus therefor, in which the shelf labels are provided with an extended bar code having the item number and price of the item. A remote unit scans the item number and price, and uses the item number to look up the item in a database which is identical to the store checkout scanner database, and compares the shelf price to the database price. If they are not the same, a new shelf label may be printed immediately. The method and apparatus described herein are easily adapted to allow government inspections of stores for shelf price accuracy. A further embodiment of the invention provides for a portable totalizer with which a shopper can total purchases as they are selected, enabling the shopper to check the scanner at the checkout register.

  • Patent number: 5375514
    Abstract: A mechanism for dual-height tables, counters, or the like, in which the top lifts and pivots upward and outward on pairs of links attached to the top and to link housings attached to the table or counter base. Each pair of links comprises a pivot link and a locking link. The pivot link has holes at each end which ride on pins or the like attached to a bracket on the top and the pivot link housing on the bottom. The locking link is similarly arranged at the top, with a hole for a pin attached to a bracket. The bottom end of the locking link has an elongated slot, through which a pin is inserted to fasten the locking link to the locking link housing. When the top is in the lowered position, the pin is in the end of the slot closest to the end of the locking link. As the top is raised, both links pivot on the pins in the link housings. When the top has reached its most-forward pivot position, the locking link rests on a forward stop.

  • Patent number: 5351643
    Abstract: Method and apparatus for rearing insects is disclosed. Information concerning the physical and dietary needs of the insect as well as behavioral characteristics are utilized to maximize the number of larvae reared per unit surface area of diet and per unit of rearing area while minimizing the amount of labor and materials required. An enclosed rearing unit is provided which can be located within an appropriate environment for rearing the insects. There are three sections within the rearing unit: 1) a diet space, 2) a larval space, and 3) a frass space. The diet space includes an appropriate diet medium for the insects. The larval space is located below the diet space and includes a series of vertical partitions perpendicular to and in contact with or nearly in contact with the diet medium such that the insect larvae are able to disperse themselves over the partitions.

  • Patent number: 5327849
    Abstract: A floating apparatus for providing pressurized air to a submerged swimmer. A floatation device supports a combination of two containers above the surface of the water. The top container, in the form of an inverted box, holds one or more electrically powered compressors. The bottom container holds a battery for powering the compressors. Water ingestion by the compressor(s) is prevented by placing the air intake inside the upper box, which forms an air trap. The air intake and compressors are isolated from any possible contamination or explosion risk from the battery outgassing, which is safely vented to the outside air from the lower compartment. Battery life is extended by pressure switch controls on the air compressor(s), running them on demand instead of continuously.

  • Patent number: 5316003
    Abstract: The transducer positioning apparatus is for positioning an ultrasonic transducer on an animal or carcass to be evaluated by ultrasonic detection equipment. The apparatus includes a support arm. A tail bone pin extends from the first end of the support arm and is for locating the transducer with respect to a tail region of the animal or carcass. A back position pin extends from the support arm and is for locating the transducer with respect to a backbone of the animal or carcass. A transducer support unit is included at the second end of the elongated support arm and is for positioning the transducer such that the transducer is parallel to the backbone. The method of positioning an ultrasonic transducer or an animal or carcass to be evaluated by ultrasonic detection equipment, is novel.

  • Patent number: 5241698
    Abstract: A clock-driven pulse source is used to apply repetitive short pulses to the squelch control point of the squelch circuitry of a radio receiver to deactivate momentarily the squelch circuitry at regular intervals (FIGS. 2B, and 2D). The repetitive short pulses being applied to the active squelch circuitry of a radio receiver to deactivate it momentarily at regular intervals may, according to the present invention, be applied directly or through reactive coupling to the antenna associated with the radio receiver (FIGS. 2M and 2N). This provides periodic noise bursts of "de-squelch" pulses on an otherwise silent radio in order to inform the radio operator that the radio is live and that the volume is adequate. A light may also be connected to the system to provide a second, visual, indicator of the operational status of the radio.

  • Patent number: 5205083
    Abstract: A new and improved method and apparatus for polishing optical lenses using free-flowing polishing fluid (23) passing across a flexible permeable membrane (1). The free-flowing polishing fluid (23) forces the permeable membrane (5) to conform to the shapes and curves of an optical lens (2), polishing and cooling the lens (2) at the same time. In addition, the free-flowing polishing fluid (23) continually replenishes the polishing compound of the polishing fluid (23) during the polishing process.

  • Patent number: 4660412
    Abstract: A three-fluid method of non-mercury liquid intrusion porosimetry. The sample to be tested and a quantity of non-wetting intrusion liquid other than mercury are introduced into a sealable, pressurizable chamber, the sample being above the intrusion liquid. The chamber is sealed and evacuated. An intermediate pressurizing liquid, such as mercury, is introduced into the chamber and pressurized by a primary pressurization fluid, such as alcohol or oil, so as to force the intrusion liquid into the pores of the sample. The volume of intermediate pressurization liquid introduced into the chamber is measured as the pressure is increased incrementally, to find the pore distribution of the sample.
