  • Patent number: 4370406
    Abstract: A single-phase, non-emulsion water containing subtractive developer for lithographic plates having photopolymer coatings is provided. These developers include water and an active or primary solvent which is only partially soluble in water and which is a good solvent for the photopolymer of a lithographic plate that has not been exposed to and insolubilized by actinic radiation, this active solvent typically being present at a concentration near its water solubility limit. Preferably, a cosolvent is also included to increase the water solubility of the active solvent when necessary. A desensitizer may be included to impart to the formulation the properties of a one-step developer or of a finisher. Formulation and development methods for these developers are also included, and they may be used either as developers or as a machine developer solution replenisher.

  • Patent number: 4366834
    Abstract: A back-flow prevention valve assembly is disclosed for use with a vacuum pump or the like and employs a valve element movable between positions opening or closing a passageway through the assembly. In the event of pump failure, a control valve, which is operated by fluid from the pressure side of the pump, vents ambient air behind the valve element to assist it in moving rapidly to the closed position to prevent backflow. After resumption of pumping, a controlled withdrawal of ambient air behind the valve element delays opening of the valve until the pump has created a sufficient vacuum to minimize influx of air upstream when the valve opens.

  • Patent number: 4367516
    Abstract: A conventional firearm having a barrel and a removable marksmanship training device which permits target practice without requiring live ammunition. In a preferred embodiment, the device includes a radiant energy emitting (e.g. strobe light) replacement unit for a cartridge cylinder of a revolver and an elongated lens tube adapted to be received within the barrel. The lens tube is structured for locking registry with the cylinder such that the radiant energy output from the cylinder replacement unit is transmittable through the lens tube as a narrow beam. The lens tube is also equipped with dual set screws which permit selective vertical and horizontal adjustment of the beam.

  • Patent number: 4361293
    Abstract: A fishing reel is disclosed of the type employing a non-rotating line storage spool, wherein line is discharged by unwinding in a generally axial direction from one end of the spool. A freewheeling flywheel is mounted coaxially in front of the spool to engage line during discharge. The freely spinning flywheel provides a feel for direction and distance of the cast, but is of sufficiently small inertia so as not to impair line discharge. The flywheel may be controlled or feathered by tactile contact with a control button coaxially mounted on a common axle with the flywheel, for rotation therewith.

  • Patent number: 4359807
    Abstract: An apparatus is provided for pulling gristle such as tendons from cuts of meat by mechanically holding down an extending portion of the gristle as the cut of meat traverses a path that intersects the location of a wedging jaw that prevents continued traversal of the meat along the path while permitting continued movement of the gristle along the path until it is stripped from the meat. In an optional embodiment, the jaw is a mechanical one that closes to form the wedging jaw that strips the gristle from the meat, after which the jaw opens to release gristle therefrom that otherwise might have been undesirably retained therein.

  • Patent number: 4360300
    Abstract: Cargo carried on freight cars such as flat bed railway cars is secured in place by lading strapping that is tensioned around the cargo so as to compress a snubber unit on a self-resetting lading tie anchor and snubbing device that includes a snubber mechanism and a lading tie anchor assembly slidably mounted in a housing secured directly to the side sill of the freight car, which anchor assembly is locked in an automatically retracted position to automatically reset the device when it drops into the housing due to the force of gravity to bring a latch into operative interengagement with the snubbing device. At this position, lading strapping is passed through a lading tie anchor that moves generally upwardly as tension is applied to the lading strapping in opposition to bias provided by the snubber mechanism.

    Abstract: Cargo carried on freight cars such as flat bed railway cars is secured in place by lading strapping that is tensioned around the cargo so as to compress a snubber unit of a self-resetting lading tie anchor and snubbing device that includes a snubber mechanism and a lading tie anchor assembly slidably mounted in a housing secured directly to the side sill of the freight car, which anchor assembly is locked in an automatically retracted position to automatically reset the device when it drops into the housing due to the force of gravity, at which position lading strapping is passed through a lading tie anchor that moves generally upwardly as tension is applied to the lading strapping in opposition to bias provided by the snubber mechanism. Unlocking of the anchor assembly quickly releases the device to substantially reduce tension within the lading strapping before it is removed from the cargo.

  • Patent number: 4360156
    Abstract: In an orifice and nozzle for the passage of fluid which may contain solid particulates as contaminants, the orifice and nozzle includes an opening which is rectangular in a cross-sectional plane perpendicular to the axis of the fluid flow. The rectangular opening has a ratio of minimum width to minimum depth, or vice versa, of less than approximately 1.5, and preferably 1.0, and a ratio of the length of the opening to the lesser of minimum width and minimum depth of the opening of less than approximately 2.0, and preferably 1.0. The rectangular cross section together with these ratios prevents plugging by the solid contaminants.

  • Patent number: 4353668
    Abstract: A bottom unit for a material transportation car hopper includes a membrane which preferably is foraminous. The membrane is oriented at an angle with respect to horizontal and slopes toward a hopper discharge pipe. The bottom unit is separate from the discharge pipe. The bottom unit includes a vibrator for vibrating the membrane, and an air injection system for defining a film of air moving up through and across the membrane for sweeping material from the membrane and into the hopper material discharge system.

  • Patent number: 4352331
    Abstract: A rail car includes substantially flat plate extensions interposed between upper and lower sections of the shell of the car to increase the internal volume of the car. The extensions are supported by lateral supports which extend laterally in the interior of the car and by longitudinal support beams also in the car interior which extend longitudinally of the extensions, are intersected by the lateral supports, and substantially prevent internal pressure in the car from being applied to the extensions.

  • Patent number: 4352861
    Abstract: A photographic paper base comprises a base paper which bears two resin layers arranged one on top of the other on at least one side. The side of the paper which is destined to receive the photographic layer is coated with two resin layers lying one on top of the other, i.e., a first layer lying on the paper and the second layer arranged to contact the photographic layer. Only the second layer contains stabilizers and/or antioxidants, these being preferably in the range 0.03 to 2.0% by weight.

  • Patent number: 4347849
    Abstract: A connector system for use with external cardiac pacers provides an electrical connection to an associated pacer lead assembly. The system includes a pair of terminal blocks each having a bore for receiving a respective connector pin of the lead assembly. A pair of locking plates pivotally mounted in wedge-shaped recesses in the connector blocks each include an aperture through which the connector pins extend. The locking plates are spring-biased into engagement with the connector pins to prevent inadvertent removal of the pins from the bores. An operator actuated release button pivots the locking plates from engagement with the pins to enable the pins to be removed from the pacer.
