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.


The invention relates to a device (14) for varying the jet form of flowable products, in particular of foodstuffs, comprising: an intake region (16) for the intake of the flowable products, a discharge region (17) for the discharge of the flowable products, and several channels (18) for conducting the flowable products, each channel (18) having at least one inlet (19) assigned to the intake region (16) and at least one outlet (20) assigned to the discharge region (17). The invention also relates to the use of said device (14) for filling foodstuffs and to a method for producing said device (14). In order to ensure that the shape and speed profile of the jet beam can be produced in a simple and easy manner, at least one of the channels (18) is curved at least in sections.


The invention relates to a method and a device for thermally activating tubular packaging sheaths (1) made of cardboard/plastic composite material, in particular for packaging for fluid foodstuffs, wherein a hot gas is applied to the tubular packaging sheath (1) using a heating device, in order to produce the base or the head of the packaging. According to the invention, in order to achieve, in a constructively simple production, a simultaneous heating for activating the contact surfaces, wherein the energy required for the activation process is used, as completely as possible, for heating the surfaces to be activated, the heating device is brought into operative contact with the surfaces to be activated, said heating device for activation being moved into the inside of the tubular packaging sheath (1). In addition, the heating device comprises a nozzle element (4) having at least one outlet opening, the outer shape of which nozzle element corresponds to the inner shape of the end to be activated of the tubular packaging sheath (1).

A firearm trigger assembly is disclosed. The disclosed assembly may include a trigger, a disconnect, and a hammer, each of which may be configured to be spring loaded when installed in a firearm receiver. Installation of the trigger assembly in a firearm receiver may include pivotally coupling the trigger and disconnect to the firearm receiver using a trigger pivot pin, and pivotally coupling the hammer to the firearm receiver using a hammer pivot pin. The trigger may include an integral sear feature configured to provide a mechanical stop to the hammer. The disconnect may be configured to be at least partially located in a disconnect slot located alongside or adjacent to the trigger sear feature when the disconnect is pivotally coupled to the trigger. The disconnect and hammer may each include integral cam features configured to buffer hammer contact during firearm recoil.


The invention relates to a processing installation, comprising at least one processing station and at least one cover at least partially surrounding the processing station, wherein the cover has at least one viewing window. Improved fault correction is enabled if a display unit displays at least one piece of information about the processing station on the viewing window.
