A device and method for inductively heating package sleeves including: at least one unit for producing an alternating current, at least one inductor having at least one effective section, and a holding unit having a front holding area and a rear holding area for mounting the inductor, wherein the inductor is connected to the unit for producing an alternating current, and wherein the holding areas arranged in such a way that a gap is formed between the front holding area and the rear holding area, the longitudinal direction of which gap corresponds to the conveying direction of the package sleeves. The effective sections of the at least one inductor may be at least in sections arranged asymmetrically to one another in relation to a center plane lying in the gap.


A method and device for thermal activation of tube-shaped packaging sleeves made of cardboard/plastic composite material, wherein a hot gas is applied to the tube-shaped packaging sleeve by a heating device in order to produce the base or the head of the packaging. To achieve even heating for the activation of the contact surfaces with production using simple construction, wherein the energy required for the activation process is used as completely as possible for the heating of the surfaces to be activated, the heating device is placed into effective contact with the surfaces to be activated by the heating device being moved inside the tube-shaped packaging sleeves for activation. The heating device has at least one nozzle element with an outlet opening, the external shape of which nozzle element corresponds to the internal shape of the end of the tube-shaped packaging sleeve to be activated.

An air gun includes two different types of energy sources that may be used to fire a projectile. A first type of energy source may include an air cylinder having a piston that moves through a cylinder, as urged by a mechanical spring or gas strut, to create compressed air charge for firing a projectile. A second type of energy source may include a compressed gas storage tank that holds compressed air, or another propellant, that is released during firing to urge the piston through the air cylinder to create a compressed air charge for firing a projectile. An air gun may, additionally or alternately, include features that promote efficient delivery of a compressed air charge to a transfer port and projectile chamber, during firing. Examples of such features include piston configurations that reduce or prevent piston rebound through the interaction of the piston face and air cylinder, upon impact.

An electronic indicator accessory may be coupled to a standard scope, which is in turn coupled to a shooting device, to indicate whether the scope is canted. The indicator may be visual, haptic, or aural. If visual, the visual indicator may include one or more LEDs positioned on the periphery of the field of view, on an accessory body attached to the scope. The accessory body may be coupled near either the ocular or objective lens of the scope. The LEDs are coupled to a microprocessor which is, in turn, coupled to a solid-state electronic inclinometer that is incorporated into the internal structure of the optical system. The microprocessor is configured to selectively illuminate one or more of the visual indicators based on the output of the inclinometer, thereby indicating how the reticle is canted, if at all.


A ball retainer for a slide apparatus and a mold for manufacturing the same. The ball retainer includes, in a width direction, a first extension part and a second extension part that are extended from a center line, forming a pre-determined angle with each other, in a length direction, a body part formed in the center, and a pair of holding parts. Each holding part is respectively formed at each end of the body part. Each holding part includes a plurality of ball insertion grooves for inserting balls that are spaced apart in the length direction. Expansion parts each having an expanding cross-sectional area are respectively formed at both sides in the length direction of the first extension part and the second extension part.


Disclosed is a method for processing cut edges of a blank member, so called package sleeve, made from packaging material, in particular paper/plastics composite material, the cut edges of which are open from above and/or below, by applying a processing medium. In order to develop a simple and cost-effective method, in which the risk of contamination of the packagins and the aseptic region of a filling installation when the package sleeves are filled and closed is reduced, the processing medium contains at least one sterilising medium and the sterilising medium remains after being applied to the cut edges and is introducted into the packaging material.


An adjustable stock assembly includes a housing, a stock rail, a release, a key movable with respect to the release, a latch rotatable about a latch pivot between a latched position, an unlatched position and a disassembly position, and a latch cam pin coupled to the release. The housing is extendable and retractable with respect to the stock rail. The stock rail has a slot and one or more recesses adjacent to the slot that can engage the latch, thereby preventing disassembly of the rail from the housing and further securing the rail in a particular configuration. When partially depressed along with the key, the release disengages the latch from the stock rail recesses, allowing the housing to extend and retract within its adjustment range. The housing can be disassembled from the stock rail when the key and release are fully depressed.

A regulator that controls an amount of energy provided to an auto loader for rounds having different gun powder loads is provided. The regulator includes a chamber, and a piston in fluid communication with the chamber. The regulator may further include a throttling valve having a first position in which pressurized combustion gas from the gas port of a barrel of a firearm can flow into the chamber, and a second position in which pressurized combustion gas from the gas port of a barrel of a firearm cannot flow into the chamber. The throttling valve is configured to move from the first position to the second position when pressure in the chamber exceeds a threshold level. The regulator may include an expansion valve in fluid communication with the chamber and arranged to move from a first position to increase a volume of the chamber when pressure in the chamber exceeds a threshold level. The regulator may include a valve including a vent hole, where the valve is in fluid communication with the chamber and is arranged to vent combustion gas from the chamber through the vent hole.

An accessory mount includes a barrel connector and multiple accessory connectors. The barrel connector removably assembles the accessory mount to the barrel of the firearm in axial alignment with the firing axis of the firearm. The accessory mount includes one or more of the accessory connectors to securely and removably assemble accessories to thereto. The accessory connectors include axial alignment features to axially align accessories with the firing axis and/or rotational alignment features to align the accessory alignment with the firing axis. Accessory connectors also include that enable an accessory to be securely assembled to the accessory mount in different rotational orientations.

A firearm assembly includes an upper receiver assembly having a front face and an aperture formed through the front face, and a feed ramp insert member removably coupled to the upper receiver assembly. The feed ramp insert member has a profile matching at least a portion of the aperture. The feed ramp insert member extends outwardly from the front face of the upper receiver assembly adjacent to the aperture. The feed ramp insert member is operative to interfere with incidental contact between a cartridge and at least a portion of the upper receiver assembly.
