  • Patent number: 5461742
    Abstract: An apparatus and method for applying textile treatment finishing agents to garments or garment work pieces is provided. The apparatus includes a rotating drum and a nozzle for generating a fine mist or fog of textile treatment agents inside the rotating drum. The apparatus can be constructed as a dedicated processing machine, or a conventional, industrial washer or dryer can be fitted with an appropriate nozzle and feed lines to provide a dual purpose machine which can be used for its originally intended purpose, and can be selectively used for applying textile treatment agents. Uniform coverage of the surface of the garment is assured by tumbling the garments through the fog created by the nozzle means. By controlling the size of the droplets, and the time during which mist or fog is generated, the amount of chemical agent absorbed by the garments can be controlled.

  • Patent number: 5456654
    Abstract: An electromagnetic transducer for improving hearing in a hearing impaired person comprises a magnet assembly and a coil secured inside a housing which is fixed to an ossicle or a middle ear. The coil is more rigidly secured to the housing than the magnet. The magnet assembly and coil are configured such that conducting alternating electrical current through the coil causes magnetic fields or the coil and the magnet assembly to cause the magnet assembly and coil to vibrate relative to one another. Because the coil is more rigidly secured to the housing than the magnet assembly, the vibrations of the coil cause the housing to vibrate. The vibrations are conducted to the oval window of the ear via the ossicles. In alternate embodiments, transducer is secured to ossicular prostheses that are secured within the middle ear.

  • Patent number: 5455721
    Abstract: A method and apparatus for automatic sector pulse generation and split field calculation in disk drives without the use of tables improves the seek latency of a disk drive system because it does not have to wait for the INDEX mark or the beginning of a frame, before beginning an operation it has been instructed to perform. The system can be designed to start from any point on the disk and begin calculations as if it were starting from the INDEX mark or the beginning of a frame. The calculations performed for each servo mark calculate the number of sectors and split fields which can be stored between servo marks on the disk. Multiple calculations can be performed between two servo marks. A counter is used to keep track of the number of servo marks for which the system has performed calculations. This counter is compared to the number of the last previously detected servo mark.

  • Patent number: 5443976
    Abstract: Antivenoms to snake, spider, scorpion and jelly fish venoms are produced for the treatment of humans and animals, and for analytical use. The antivenom is purified with an antigen matrix containing a single whole venom or a plurality of whole venoms covalently attached to an insoluble support such as aldehyde-activated agarose. Preferably, the whole venoms forming the plurality of whole venoms are selected from the four whole venoms from C. atrox, B. atrox, C. adamanteus and C. durissus terrificus. A combination of immobilized C. atrox and C. durissus terrificus whole venoms can substantially purify antivenom reactive with all four venoms. The antivenom can be horse or avian such as chicken antivenom.

  • Patent number: 5427488
    Abstract: A threaded fastener has a casing enclosing at least three radially inwardly biased arcuate segments positioned to engage the threads of a bolt or hollow threaded member. The casing defines spaced apart internal frustoconical surfaces positioned to engage corresponding surfaces of the segments in the same axial direction. The radially inner ends of the frustoconical surfaces are directed toward a first end of the fastener, and the diameter of the radially inner end of the frustoconical surface away from the first end of the fastener is less than the radially outer diameter of the other frustoconical surface. The threads of the segments substantially fully engage the threads of the bolt or hollow threaded member.

  • Patent number: 5428411
    Abstract: Protective eyewear for sports activities and the like having a resilient rigid frame is disclosed. Included is a sealing area around the eyes having a web which diverges outwardly in every direction toward the lens frame. The frame is curvedly contoured around the face of the user and in conjunction with the diverging web, provides both maximum eye protection and peripheral visibility. A semi-rigid frame provides for temple mounting and obviates the need for around-the-head straps.

  • Patent number: 5428564
    Abstract: A content addressable memory cell includes six transistors connected together to perform memory read, memory write, and matching operations. This cell has the ability to perform typical memory write and memory read operations as well as the capability of signalling whether or not its stored data matches data that is being searched for. A cross-coupling scheme is used in the memory cell so that a high potential will always be stored on the gate of a transistor whose source is at ground. This cross-coupling scheme increases the amount of charge stored on the storage transistor and decreases the required frequency of refresh operations. In addition to the transistors configured to store data, an additional transistor configured as a diode is used as a rapid discharge path to maximize the efficiency of the cell during a read operation. During a match operation another transistor is utilized to discharge the Match line quickly in the event the stored data does not match the data that is being searched for.

  • Patent number: 5425244
    Abstract: A broad range cooling system is provided which can operate over a temperature range of -25.degree. F. to 75.degree. F. under any expected ambient temperatures. The system includes two compressor systems which are configurable to operate independently, or as a cascade system, depending upon the desired temperature requirements of the load in relation to the ambient. There are two separate evaporator systems for cooling air which is used to cool the product; one evaporator system for each compressor. In single compressor mode, the selected compressor is used to cool its respective evaporator system and each compressor system is automatically configured to utilize the primary condenser to convert hot gas to a liquid. In cascade cooling mode, the lower compressor system is automatically reconfigured to utilize an evaporator side of a heat exchanger to convert hot gas to a liquid and to utilize the primary condenser to evaporate the liquid to a cold gas while absorbing heat.

  • Patent number: 5418473
    Abstract: A complete logic family which is SEU immune is constructed, using logic/circuit design techniques, to recover from an SEU, regardless of the shape of the upsetting event. The logic family provides a redundancy of data to be used to restore data lost by an SEU. Two transistor networks are used, a p-channel network and an n-channel network. Each transistor network consists of a plurality of input transistors and a feedback transistor. The feedback transistor is sized to be weak compared to the input transistors. The transistor networks are designed to either resist an SEU or to shutdown until the SEU is over and then the network which is not shutdown will restore the data of the network that was hit by the SEU. The logic family can prevent glitch propagation from an upset node and can be implemented in a standard, commercial CMOS process without any additional processing steps. The logic family includes but is not limited to an Inverter, 2-input Nand, 2-input Nor, 3-input OrNand and a 3-input AndNor.
