  • Patent number: 5236001
    Abstract: The remote control valve has connected to it an oxygen supply, an air supply, an underwater oxygen-arc cutting torch and an air cylinder that operates a knife switch. When the oxygen valve on the underwater oxygen-arc cutting torch is depressed the oxygen flows through the front body orifices and out through the oxygen outlet port to the underwater oxygen-arc cutting torch at the required pressure and volume. Also as the oxygen flows through the front body it shifts the piston and spool valve to the open position and the spool valve directs the air pressure from the air inlet port to the air outlet port which extends the air cylinder and closes the knife switch. When the oxygen valve on the underwater oxygen-arc cutting torch is released the oxygen flow stops and the spool valve and piston are shifted to the closed (exhaust) position by the compression spring and the air cylinder is exhausted out through the air exhaust port which opens the knife switch.

  • Patent number: 5168802
    Abstract: Apparatus for peeling fruits and vegetables comprises a plurality of rotatably driven peeling elements having predetermined axes of rotation that are generally horizontal and substantially parallel to one another. The peeling elements have a provision for engaging the peel of the fruits and vegetables. A plurality of flexible, elongate, peeling enhancement fingers, each having a first end and a second end, are mounted to the apparatus above the peeling elements by their first ends. The first ends lie in a generally horizontal row that is generally parallel to the axes of rotation of the peeling elements. The fingers extend generally toward the peeling elements with the second end of each finger being proximal at least two peeling elements, so that the finger engages the item of fruit or vegetable being engaged by the adjacent peeling elements. A support structure provides support for the peeling elements, fingers and drive mechanism.

  • Patent number: 5170358
    Abstract: A method of controlling chatter in a rotating, chip cutting machine tool cutting at a predetermined depth on a workpiece in which the speed of rotation of the cutting tool relative to the workpiece and the rate of speed of the cutting tool relative to the workpiece both adjustably controlled between predetermined minimum and maximum rates for the particular combination of machine tool and workpiece material. The method includes the steps of detecting vibration signals representative of relative vibrations between the machine tool and the workpiece and generated by preliminary operation of the machine tool at predetermined conditions, processing that generated signal as a function of signal frequency, obtaining a signal indicative of the rotational speed and determinating the threshold of the signal level above which are excluded harmonics of the predetermined rotational frequencies that are indicative of chatter in the cutting tool.

  • Patent number: 5157811
    Abstract: An improved form, fill, seal and separate packaging machine for reclosable containers is accomplished by a plurality of stations disposed along a path of travel of a thermoplastic web including means to attach a pair of mated, resealable closure strips to the base web. The machine is intermittent in its operation, with movement of the web through the machine controlled so that the various steps of applying the closure strips, forming, filling, sealing and separating the reclosable containers are performed during periodic stops of the machine. The machine is further characterized by its use of two pairs of web belts to move the web through the machine. A first pair of web belts initially receive the folded web stock and partially form and completely fill the containers. The second pair of web belts overlap with the downstream end of the first pair of belts, but are disposed lower than the first belts.

  • Patent number: 5156484
    Abstract: A rafter reinforcement device for strengthening structural joints that are primarily of the type used to connect sections of hollow rafters in roof support systems. The rafter system to be reinforced includes a pair of "U"-shaped members, each of which are composed of two segments that are joined at an angle. The "U"-shaped members are nested together creating a space to receive the reinforcement device. The reinforcing device includes a pair of "U"-shaped channels, each composed of two parts that are joined at an angle that is substantially the same angle as that defined by the rafter segments. The channels are nested with one another so that the web of each channel is opposed and spaced apart from the web of the other channel. The nested channels are sized and configured to be received by the hollow rafter at the structural joint of the rafter.

  • Patent number: 5133622
    Abstract: An improved water distribution system of the type that includes a distribution conduit and an irrifluent pipe disposed on or below ground for dispersing water at a controlled rate. A first pump connected to the distribution conduit passes the water through the main delivery conduit and through apertures in the irrifluent pipe. Solid matter collects within the irrifluent pipes when the dispersion of the water through apertures in the irrifluent pipes is at low pressure. The improvement includes a return conduit that is disposed in fluid communicating relation to the irrifluent pipe, and a second pump, connected in fluid flow relation to the return conduit. The second pump is operated intermittently with the first pump to increase the flow rate sufficiently to flush the collected solid matter from the irrifluent pipes and through the return conduit.

  • Patent number: 5127276
    Abstract: An inspection drain plug that is removably connected to an aperture in a fluid reservoir. The drain plug comprises an outer hollow body having an open first end and an open second end, the first end being removably connected in a fluid flow relationship to the aperture of the fluid reservoir. A valve mechanism is connected to the outer body, such that the valve mechanism may be selectively operated between an open and closed position, so that the first end of the outer body is closed when the valve is in the closed position. The drain plug also comprises a biasing mechanism, whereby the valve is biased toward the closed position. The first end of an inner hollow body, having an open first end and a closed second end, is removably inserted within the second end of the outer body. Upon insertion of the inner body within the outer body the closed second end of the inner body operatively engages the valve, thereby selectively moving the valve between the closed position and the open position.

  • Patent number: 5099226
    Abstract: An intelligent security system capable of sensing the presence of an object to be identified, interrogating the object with an encrypted code, and receiving and processing an encoded response from a passive transceiver carried by the object so that the intelligent security system can be utilized for controlling access to a location, performing inventory control, controlling toll access systems, operating multi-station complex machinery systems, or providing object locating information, for example. The intelligent security system is particularly characterized by its utilization of a totally passive transceiver including a transmit circuit which will only be activated upon receipt by the transceiver of a predetermined encrypted interrogation signal. In response to receipt of a proper interrogation signal, an encoded response signal is transmitted by the passive transceiver and then received, decoded and processed by other elements of the security system.
