  • Patent number: 4174720
    Abstract: A filter is formed by placing increments of glue in spaced apart relation on a moving stream of plug wrap paper and thereafter depositing alternating fibrous filter sections on the glue increments. Particulate marterial is then deposited between the fibrous filter sections and the plug wrap paper wrapped about the filter sections to form an endless rod. Two-filter filter plugs are severed from the rod by cutting through the unglued fibrous filter section and thereafter the charges of particulate filter material are compacted by moving the unglued outer filter sections of each plug inwardly. Each plug is then joined to two tobacco columns and cut in half. The resultant filters each have a fibrous filter section at the exposed end glued to the plug wrap paper, a compacted particulate section and an unglued fibrous filter section at the tobacco end.

  • Patent number: 4174728
    Abstract: This invention is a novel valve of the slidable-gate type. The valve is designed especially for long-term use with highly abrasive slurries. The sealing surfaces of the gate are shielded by the valve seats when the valve is fully open or closed, and the gate-to-seat clearance is swept with an inflowing purge gas while the gate is in transit.A preferred form of the valve includes an annular valve body containing an annular seat assembly defining a flow channel. The seat assembly comprises a first seat ring which is slidably and sealably mounted in the body, and a second seat ring which is tightly fitted in the body. These rings cooperatively define an annular gap which, together with passages in the valve body, forms a guideway extending normal to the channel. A plate-type gate is mounted for reciprocation in the guideway between positions where a portion of the plate closes the channel and where a circular aperture in the gate is in register with the channel.

  • Patent number: 4174731
    Abstract: A conduit coupling includes an improved plug assembly. The plug assembly has a valve which limits excess flow in the direction of normal flow and prevents backflow in the opposite direction. The valve includes a valve member which is operated from a first closed condition to an open condition in response to a pressure differential caused by normal flow. The valve member further moves to a second closed condition in response to a predetermined pressure differential across the valve member which would result in an excess flow in the downstream direction. The valve member operates from its open condition to the first closed condition whenever the difference between the upstream pressure and the downstream pressure is less than a predetermined amount, thus preventing backflow. A leak down passage is provided which allows fluid to flow through the valve assembly even when the valve is closed.

  • Patent number: 4174735
    Abstract: A method of temporarily sealing off the open ends of a plurality of fluid transport conduits that terminate in a common header space. A sealant material in the liquid state, preferably enclosed in a flexible envelope of non-permeable resilient material, is introduced through an access opening into the header space of, for example, a multi-tube heat exchanger. Sufficient sealant material is introduced to at least partially fill the header so as to close off the openings to the desired number of fluid transport conduits (e.g., heat exchanger tubes). The sealant is subsequently converted to the solid state, thereby providing simultaneously a firm, vacuum-tight seal for the end of each conduit to permit, for example, the identification of a leaking tube by conventional vacuum testing techniques. Following completion of such test procedures, the sealant material can be removed from the header by first reliquefying it, and then draining the sealant material from the header.

  • Patent number: 4174766
    Abstract: A speed shift indicating device is mounted in the driver compartment of a motor vehicle and is connected to the ignition system by a single wire which extends from the driver compartment through the firewall and into the engine compartment. The single wire derives from the ignition system an electrical input signal having a repetition rate indicative of engine revolutions per minute (RPM). The speed shift indicating device has an electrical circuit connected to the single wire for receiving an input electrical signal which has a repetition rate indicative of engine RPM. Trigger pulses are produced in response to the input electrical signal and are supplied to a timer. The output of the timer switches to a first state in response to each trigger pulse and remains in the first state only for a first time period unless another trigger pulse is received before the end of the first time period. The first time period is adjustable by the driver.

  • Patent number: 4174767
    Abstract: The invention provides for a cartridge for lubricant which is designed for use in an air line lubricator. The cartridge comprises a rigid sleeve defining an outlet nozzle for lubricant at its one end, with the other end being open and directed in use into the stream of pressure air flowing through the lubricator. A flexible sock with its mouth region secured within the sleeve acts physically to separate lubricant in the sleeve from the pressurized air, the body length of the sock being sufficient to permit exhaustion of lubricant from the sleeve. The sock may be secured within the sleeve at the outlet end thereof, midway there-along, or at its open end. In the latter case a method of charging the sleeve in accordance with a further aspect of the invention comprises locating a second sleeve within the cartridge sleeve so that during the charging process the sock is folded back on itself through the action of the secondary sleeve. After charging the secondary sleeve is withdrawn.
