International Classification:

F42B 3304
F42B 3310

US Classification:

86 36

Abstract:

The present invention defines a precision primer-reloading assembly to be mounted in and operated by a suitable cartridge-reloading press. The assembly includes a tubular support-body member having a ram rod mounted therein so as to be positioned within the cartridge case at the time the primer is loaded. The support-body member is mounted to the reloading press above and in alignment with a primer-guide assembly which is mounted to the press ram of the reloading press. The guide assembly includes a guide base having a primer-guide pin. A coil spring is positioned on the guide base so as to engage the guide housing that is slidably mounted over the guide base, the guide housing being formed with a closed end having a centrally positioned recess. This recess is provided to support and align the cartridge case with the ram rod, whereby the primer can be loaded in the primer pocket of the case by means of the primer pin as the ram rod is activated. One or more shim members are provided to allow the primer to be selectively positioned at a predetermined location within the primer pocket.

International Classification:

F02B 3104

US Classification:

123306

Abstract:

A cylinder head for a four-cycle internal combustion engine with improved intake port and combustion chamber configuration. The physical shape of the intake port and combustion chamber directs the flow of the incoming air/fuel mixture in a swirl path, which is directed toward the spark plug. In particular, the intake port has a fin at its terminal opening into the combustion chamber. The fin creates a swirling motion in the incoming gasses and also directs the flow of the gasses toward the spark plug. As a result, a greater percentage of the intake charge is in close proximity to the center of the combustion chamber and the spark plug, and hence combustion occurs faster and more completely. In a preferred embodiment of the invention, the portion of the cylinder head that forms the upper surface of the combustion chamber, includes a shear ledge that further acts to direct the flow of the incoming gasses toward the sparkplug. The shear ledge acts as a secondary boundary for the gasses that go past the intake port fin, directing that portion of the charge that goes past the intake port fin toward the center of the cylinder and closer to the spark plug.

International Classification:

B32B 306
B42F 300

US Classification:

428100

Abstract:

A flexible panel or sheet adapted for installation in a printer for separating the incoming blank paper web from the outgoing printed paper web. The sheet is wide enough to span (overlap) perforations in edge areas of the paper that are used to pull the paper web through the printer. By providing a physical separation between the incoming paper and outgoing paper it becomes possible to prevent uneven paper backups, misfeeds or uneven paper movement caused by tiny slivers of paper lodging or catching in the drive perforations when the webs come into contact with each other. The separator sheet is attached to the printer by two spaced-apart straps that extend from the sheet around a pre-existing crossbar in the printer. The straps lie in the general plane of the separator sheet to minimize the sheet thickness; cutouts in corner areas of the sheet accommodate the straps. The straps are of adjustable length to permit optimum positionment of the separator sheet.

International Classification:

F02M 3510

US Classification:

12318446

Abstract:

An intake manifold for a four-cycle internal combustion engine with multiple stages to reduce imbalances in volumetric efficiency and air/fuel ratio. The intake manifold utilizes at least two ram stages coupled by a plenum chamber. The first stage includes a ram tube that carries the air/fuel mixture from the carburetor, or throttle body to the plenum chamber. The second stage includes at least two ram tubes that carry the air/fuel mixture from the plenum to a plurality of intake valves through cylinder head intake ports. The plenum chamber acts as a buffer between each intake valve and the carburetor or throttle body. The air/fuel mixture enters the first stage ram tube and passes into the plenum chamber. These gases then pass into either one of the second stage ram tubes, depending on which cylinder is at its intake stroke. By drawing the air/fuel mixture from the plenum instead of directly from the first stage ram tube, differences in the air/fuel ratio and volumetric efficiency are minimized.

Abstract:

Methods and systems are described for conserving energy used by an energy consuming device. In certain embodiments, an energy conservation system can be configured to deliver energy to the energy consuming device for a period, followed by a period where energy delivery is dampened and/or cut. By cycling the delivery of energy in this fashion, the energy conservation can achieve a pulsed efficiency.
