Abstract: A rail anchor drive machine for boxing and then driving two coacting rail anchors in sequential operations. The machine is operated by a single operator and includes a wheeled frame adapted to be moved along a railroad track having two rails, and an anchor drive mechanism operatively mounted on the frame for operative positioning on either of the two rails when the wheeled frame is disposed at a preselected position on the track. The boxing operation is effected by a single hydraulic piston-cylinder mechanism and the anchor driving operation is effected by a single hydraulic piston-cylinder mechanism. The anchor drive mechanism is free of sliding members, with all connections therein being pivotal.

Abstract: A containment and storage system for liquids, such as petroleum based liquids, for use for instance in a railroad track environment, comprising a walled containment reservoir formed in the ground and opening upwardly, with the containment reservoir including a flexible impervious liner to prevent escape of liquid through the liner from the containment space, and a receiving or storage reservoir disposed in spaced relation to the containment reservoir and means coacting between the reservoirs for transferring liquid caught in the containment reservoir, to the storage reservoir. In one embodiment, a mechanical pump is utilized for transferring to the storage reservoir liquid caught in the containment reservoir. In another embodiment, gravity flow is utilized for transferring such liquid. An improved arrangement is disclosed for handling liquid caught in the containment reservoir, and preventing leakage from the reservoir, at the exit point from the containment reservoir.

Abstract: A trigger operated tool handle electrical switch in which each conductor wire connected to the switch is releasably secured therein by a spring-like retainer blade biased diagonally against the wire. Each retainer blade has a release arm for deactivating the retainer blade thus permitting easy withdrawal of the conductor wire. The release arm has a laterally extending handle lug on its exteriorly exposed free end to provide a handle and also to provide for engagement with the switch housing to limit inward movement of the release arm. The inner end of the release arm is beveled to provide a plane-to-plane contact with the retainer blade for a positive contact therewith.Each conductor wire connected to the switch is releasably secured therein by a spring-like retainer blade biased diagonally against the wire. Each retainer blade has a release arm for deactivating the retainer blade thus permitting easy withdrawal of the conductor wire.

Abstract: An on-line filtration system for the removal of macromolecules greater than 70,000 mol. wt. from a physiological solution, such as blood, in the therapeutic treatment of various disease states. For blood, the plasma (which contains the macromolecules) is separated continuously from the blood using a first membrane filter with a membrane porosity of nominally 0.2 to 1.0 micron. The separated plasma is then continuously filtered in a physiological temperature state or a cooled state through a second membrane filter with a membrane porosity of nominally 0.01 to 0.2 micron, which retains the macromolecules. In the cooled state, separation of the macromolecules is effected more efficiently than could be done in the non-cooled state. The treated plasma (macromolecules removed) is then reunited with the blood flow coming from the first plasma filter and returned to the patient. The blood flow and filtration processes are generally continuous.

Abstract: A mounting device for mounting a necked container such as a glass baby food jar, to a board support, such as a perforated board support; the device comprising a generally resilient C-shaped base for receiving and holding the neck of the container for suspending of the container from the device and means for coupling the device to the board support. The container is adapted to be assembled to the device by forcing the neck of the container through the open portion of the C-shaped base, whereby the arms of the base are forced outwardly during the insertion and/or removal of the container from the mounting device. The device which is preferably molded from plastic, enables rapid assembly and disassembly of the container to and from mounted condition on the board support.

Abstract: In a typical breading machine for automatically coating the exterior surfaces of edible products such as for example seafoods, poultry, red meats and vegetables, a method and apparatus for distributing and sifting what is defined in the art as Japanese style bread crumbs which display a wide variation in crumb sizes. The typical breading machine provides for the conveyance of the product to be coated along a conveyance or coating path on a bed of breading placed on the conveyance means at a first location whereby the surfaces of said product which engage said bed are coated with breading. A separate quantity of breading is subsequently presented to the product being conveyed at a second location along the conveyance path whereby the remaining surfaces of the product are coated with breading.

Abstract: An electrical switch having spaced stationary contacts and a contact carrier carrying a bridging contact in linear reciprocation relative to the stationary contacts, with the bridging contact biased toward the stationary contacts. The bridging contact has spaced opposite contacting ends forming a leading contact end and a trailing contact end for sliding movement between a bridging position where the contacting ends contact their respective stationary contacts, and a non-bridging position where the leading contact end is out of engagement with its stationary contact. The bridging contact is rotatably hinged to the contact carrier and a projection is disposed between the stationary contacts for engagement with the leading contact end for pivoting and lifting the leading contact end from its stationary contact in coaction with the hinged connection with a quick break action during movement of the contact carrier to the non-bridging position.

Abstract: A contact lens for the correction of astigmatism or presbyopia and for the correction of "high riding" lenses being of lenticular construction. This invention avoids unwanted increase in center thickness of the lens and unwanted prism in the central area. The curved lenticular carrier portion of the lens, the non-visual portion, is constructed with a concentric curve cut which produces a thick lens edge. The lenticular carrier is also provided with a second eccentric curve cut, with respect to the visual axis of the lens, to provide a thickness disparity between the superior and inferior portions of the lens and to provide an offset center of gravity and a desirable rotational positioning of the lens in the eye of a wearer, particularly when the lens is of astigmatic or bifocal type.

Abstract: A material removal device for removing auger spoil from a drilling site (such as, for example, an earth situs). A hollow spoil-receiving container is provided having an inclined floor and having a generally vertically disposed barrel portion secured to the inclined floor adjacent the upper end thereof for enclosing a preselected axial length portion of the auger with a snug operable fit. The auger is operably movable in the container barrel portion during drilling to permit the spoil from the drilling operation to be carried upwardly through the barrel portion by the auger flights and deposited in the main part of the container. The container also has a selectively lockable door vertically hinged on the container at a point adjacent the lower end of the container inclined floor. A generally vertically disposed elongated framework structure is secured to the container and extends upwardly therefrom.

Abstract: An air pressure responsive liquid level valve used in filling a liquid storage tank to control the tank emergency loading valve which is held open by pressurized air.The liquid level valve has an air control cavity connected to the pressurized air and an actuating cavity exhausting to the atmosphere and is disposed above the air control cavity and connected to it via an actuating passageway. An air control diaphragm divides the air control cavity into upper and lower portions and controls the flow of pressurized air into such lower portion which exhausts to the atmosphere. The air control diaphragm has a small air control passageway (of smaller diameter than the actuating passageway) allowing pressurized air into the air control cavity upper portion, thus permitting the pressurized air to act on both sides of the air control diaphragm. An actuating diaphragm, responsive to increased pressure within the liquid level valve, controls the flow of pressurized air through the actuating passageway.
