Abstract: Magazines with guard elements have a tubular body having a lower end and an upper end and defining an interior space, the body having opposed lateral sidewalls, and opposed front and rear walls, at an intermediate portion along the length of the body between the upper and lower ends, a sidewall defining a magazine catch opening, the magazine catch opening having an upper limit including a downwardly-facing ledge surface configured to engage a latch, and a recessed guard element at the magazine catch opening configured to prevent intrusion of the firearm latch into the interior space. The recessed guard element may protrude into the interior space. The tubular body may have a wall thickness adjacent to the recessed guard element, and the recessed guard element may have the same wall thickness. The tubular body may be formed of an articulated sheet.

Abstract: An improved fuel injection device for internal combustion engines comprising a slidable (pilot) valve instead of a needle valve principle. The valve does not comprise a seat, so, even in the case of a spring-loaded embodiment of the valve there is no risk of hammering of the valve on a seat with the pertaining generation of noise. The improved fuel injector allows a larger nozzle diameter and, therefore, a larger number of nozzle holes, if required or deemed useful. For rotating embodiments of the fuel injector, the valve or at least its spring, in the case of a spring-loaded embodiment of the valve, can be located in the static section of the rotating fuel injector, thus eliminating the balancing problem of prior art rotating fuel injectors which comprise a spring in the rotating section.

Abstract: Magazine floor plates have a tubular body defining an elongated passage and having a lower end and an upper end, a floor plate element connected to the lower end, a follower movable within the elongated passage, a spring within the passage having a first end contacting the floor plate element, and having an opposed second end contacting and biasing the follower toward the upper end of the body. Downward force exerted by the spring on the floor plate element retains the floor plate element in an installed position relative to the lower end of the body. The floor plate element may have a width narrower than the elongated passage. The floor plate element may be connected to the lower end of the body by rails on the lower end of the body. The floor plate element may have an upward protrusion.

Abstract: A method for producing an iron-based alloy clip-on wheel balance weight composed of an iron-based alloy weight body and a clip having one end caulking embedded to the weight body. The method includes the following steps: (1) prefabricating the iron-based alloy weight body and the clip, and (2) fixing the clip to the iron-based alloy weight body by caulking the clip to embed in the weight body to form an iron-based alloy clip-on wheel balance weight. The second step is performed in three axes to control positioning of the clip on the weight body.

Abstract: A wheel balancing device of this invention comprising a wheel balancing body having a wheel rim engaging bar made of iron metal or iron-based metal component to be formed in any shape as required. Being provided on one side of the wheel balancing body is an engaging part fixed thereto. The engaging part is composed of an engaging plate having one end engaged and fixed to one end of the wheel rim engaging bar by a locking means and the other end is bent as an upper curve to be locked and fixed to a wheel rim of an automobile. The wheel rim engaging bar and a part of engaging plate are enwrapped by the outer cover plate made of plastic or plastic-contained composition.

Abstract: A sampling system for separating gaseous samples from a gas stream containing particulate matter and transporting the gaseous samples to a location outside of the flowing gas stream comprises an inertial filter mounted on the end of a hollow probe, the inertial filter positioned within the flowing gaseous stream. The inertial filter comprises a filter media mounted within a tube such that a portion of the particulate-containing gaseous steam flows through an annular space between the filter media and the tube wall, the gas to be sampled passes through the filter media into an inner space and the filtered gas is then delivered through the hollow probe to analytical devices external to the space containing the flowing gas stream, such as a flue stack.

Abstract: A tamper evident cover is provided for engaging a container cap or drum bung, which cover has a plurality of locking teeth that snap under and engage a lip of the container cap. A frangible strip permits severing the cover to facilitate removal of the cover, and a series of tabs extend from the locking teeth and bear against the outer edge of the lip of the container cap to prevent any forcible removal of the cover without substantial damage to or destruction of the cover.

Abstract: Methods and compositions for cleaning and maintaining chemical, biological and radiological countermeasure washdown systems are disclosed. Systems are effectively cleaned by the removal of water scale, including deposits, sediment, microbiological scale, microinvertebrate fouling, and the like, from the inside surfaces of piping in the system. A section of the system is isolated for cleaning and an aqueous acidic cleaning solution is circulated through the fouled pipe section to be cleaned for a sufficient time and at a controlled pH to dissolve and loosen the scale. After cleaning all of the sections, the system is restored to operational readiness.
