The invention discloses an engine braking method. A cam roller is moved by an axial driving mechanism of the cam roller from a first axial position to a second axial position on a roller shaft, connection between the cam roller and a conventional ignition cam is switched into connection between the cam roller and an engine braking cam, movement of a conventional ignition valve stops, and movement of a braking valve of an engine is generated. The axial driving mechanism of the cam roller can be integrated in a valve actuator such as a rocker arm and can also be located outside the valve actuator; for example, the axial driving mechanism of the cam roller is fixed to the engine. By means of the engine braking method, high-power braking generated by the special braking cam is obtained, the special braking cam can only comprise a braking exhaust cam body and can also comprise the braking exhaust cam body and a braking admission cam body at the same time, engine braking is constructed as non-hydraulic fixed-chain type bearing, and the efficacy losing mode of hydraulic bearing is avoided. The braking control is simple, the braking performance is excellent, the structure is simple and compact, manufacturing and assembling are easy, and the application range is wide.

An edge coated gasket includes a base sheet made of compressible gasket material and having opposed faces and an interior edge surrounding and defining an aperture. An edge coating of polymer or other material is disposed on and seals the interior edge of the base sheet and may project beyond the facial planes of the base sheet to define protruding rims extending around the aperture. Face coatings may also be applied to one or more of the faces extending in relatively narrow strips around the aperture of the base sheet. When clamped between flange surfaces, the edge coating engages, conforms to, and seals against the flange surfaces to provide a seal against both interfacial and intersticial migration of fluid past the gasket. At the same time, the inherently good compression failure resistance of the compressible gasket material of the base sheet is preserved. Thus, a gasket with enhanced sealability and compression failure resistance is provided. A unique method of making such an edge coated gasket is also disclosed.

A ceramic card having a thick film network, with conductive vias formed as part of the card. Each of the vias is in electrical communication with both sides of the thick film network, allowing the pads and the pad senders to be formed on both sides of the card. This configuration maintains the contact when one of the connectors is subjected to bending force or is otherwise displaced, maintaining contact with at least one of the pads, and allowing the system to still function. The double sided thick film network allows for each connector to touch both sides of one of the pads, and still maintain electrical communication with the level sender, thus eliminating the failure mode of intermittent contact with the thick film network resulting from movement of the connector.

A multi-layered pouch capable of holding pharmaceutical related items. The pouch includes first and second sides engaged along a plurality of extending and interconnected edges thereof and in order to define a hermetically sealed interior for holding the items. Each of the sides exhibits a multi-layered construction including an outer high density polymer film, coated with a clay material, a lower density polymer film secured to an exposed side of the high density polymer film, a metal foil layer secured to an exposed inner facing side of the lower density film, and a sealant resin layer secured to an exposed facing side of the foil layer. In use, the pouch exhibits tear resistant properties and such as which prevents a child from biting into and opening the pouch.

This improvement to a pneumatic return mechanism for percussion foot pedals incorporates a flat or bowl-shaped diaphragm rather than a rolling diaphragm, and a piston which is spherical rather than cylindrical, producing a bouncy feel for the player. A further improvement to the track hub of a percussion foot pedal enables bump fasteners to be removably inserted, to add lift and alter beater acceleration. A further improvement is a removable stiffener which prevents slack in the connector between the footboard and track hub of the percussion foot pedal, which may occur during fast drumming.

The present invention relates to an aerosol-generating system comprising a liquid storage portion for storing liquid aerosol-forming substrate, wherein the liquid storage portion comprises a movable wall and an outlet, a vaporiser comprising a heating element having a structure defining an open-ended internal passage for heating deposited liquid aerosol-forming substrate, a pump configured for delivering liquid aerosol-forming substrate from the outlet of the liquid storage portion to the internal passage of the heating element, the pump comprising a micro stepper motor with a drive shaft thatis configured to rotate for a predetermined amount upon performing one step of the micro stepper motor, a piston connected to the movable wall, and a lead screw connecting the drive shaft to the piston and configured to translate a rotation of the drive shaft into an axial movement of the piston and a corresponding axial movement of the movable wall, wherein the vaporiser is configured for heating the delivered liquid aerosol-forming substrate in the internal passage to a temperature sufficient to volatilize at least a part of the delivered liquid aerosol-forming substrate. The present invention further relates to a cartridge for an aerosol-generating system, wherein the cartridge comprises the liquid storage portion, the piston, and the lead screw. The present invention further relates to a method for generating aerosol.

An infinite switch includes a front cover, a back cover, and a base secured between the front cover and the back cover. A floating shaft extending through the front cover and the base. A cam fixed to the base and slidingly receiving an end of the floating shaft. The floating shaft is moveable in an axial direction extending parallel to a longitudinal axis of the floating shaft and the cam is fixed to prevent movement in the axial direction.

A method and apparatus for reducing the volume of a cylindrical tube for disposal by crushing flat and then shearing into small coupons. Shearing is accomplished by opposed dies having a checkerboard grid of cutting edges. The resulting coupons are preferably substantially square in shape. The invention is particularly useful for reducing the storage volume of irradiated radioactive pressure tubes from a nuclear reactor.
