Abstract: The present disclosure relates to systems, apparatuses, and methods for assembling cartridges for aerosol delivery devices. The cartridges may be assembled by coupling a base of the cartridge to a carriage that is transported via a track. The track transports the carriages between various substations at which one or more parts are added to the base. The carriage may be lifted from the track by a lifter mechanism at each substation in order to perform assembly operations on the base. An inspection system may inspect the cartridges at various stages of completion at or between the various substations.

The tool spindle and the at least one jig are arranged on a common machine frame. There is also provided a workpiece transport device, which is arranged on the machine frame, and which is adapted to perform at least one of introducing unmachined workpieces into the at least one jig and removing machined workpieces from the at least one jig.

Abstract: A machining device for material-removing machining of a workpiece includes a stationary frame, a workpiece magazine, a workpiece slide movable relative to the frame and accommodates a workpiece and a housing which encompasses a machining chamber and is located outside the workpiece magazine, wherein the workpiece magazine accommodates a plurality of workpieces, the workpiece magazine moves workpieces to an interchange point, the workpiece slide imparts translational movement to a workpiece along an X axis during workpiece machining and the workpiece slide is movable along the X axis to such an extent that the workpiece located on the workpiece slide is movable to the interchange point disposed outside the machining chamber encompassed by the housing.

Abstract: A band saw machine with a rod having an adjustable position to accommodate various sized workpieces includes a movable member which is mounted on a saw frame and movable relative to a movable clamp arm. The movable member and the fixing member each have a rack, and the racks are in parallel to each other. The rod includes a gear shaft engaged with the racks. When the movable clamp arm moves to accommodate the size of a workpiece, the rack of the movable member drives the gear shaft to move along the rack of the fixing member, which causes position change of the rod, so that the rod is automatically moved to a position where it can detect the workpiece in a reliable manner. Therefore, the size of the workpiece to be clamped is not limited by the position of the rod anymore.

Abstract: The present invention relates to a device for the treatment of a workpiece, in particular of a substantially flat substrate, comprising a table (2) for supporting the workpiece (5), a flow generation apparatus (6, 11) producing a gas flow (22) on a top face (17.1, 17.2) of the table (2) in a region between the workpiece (5) and the top face (17.1, 17.2) of the table (2), on which gas flow the workpiece (5) is supported during the treatment.

Abstract: A panel mount for non penetrative fastening of a panel (such as a glass pane). The panel mount has clamp jaws defining an elongate slot in which an edge of a panel can be received. A foot is provided for mounting and fastening the clamp jaws to a structure. At least one of the clamp jaws carries at least one threaded fastener that can be actuated by a user, including when the foot is fastened to the structure. The threaded fastener(s) of the at least one clamp jaw, in cooperation with the other clamping jaw, is capable of operatively clamping the panel to hold it in the slot, irrespective of any non-parallel disposition of the plane of the panel to the elongate direction of the slot.

Abstract: A work support comprises a plunger, a transmission member, a first chamber, a second chamber, a third chamber, a clamping mechanism, a plug, and a body. The plunger may be slidably retained within the clamping mechanism, which in turn is firmly held within the transmission member. The transmission member may extend and retract from the body corresponding to a pressure in the first chamber and the second chamber. Extension of the transmission member also extends the plunger such that the plunger may contact and receive a load from a work piece. The third chamber may be located between the outer surface of the clamping mechanism and the inner surface of the transmission member. Increasing pressure in the first chamber while decreasing pressure in the second chamber extends the transmission member and opens the plug which blocks the entry to the third chamber. Pressure in the third chamber closes the gap between the clamping mechanism and the plunger and applies a clamping force to the plunger.

A plurality of slide portions (61) opposed to each other across the plug member (12) are arranged around the plug member (12) movably in a first radial direction (D1) substantially orthogonal to the opposed direction thereof. A first pressing member (15) and a second pressing member (19) are arranged outside the slide portions (61) diametrically expandably and diametrically contractibly and axially movably. The first pressing member (15) is driven toward a base end by a drive device, whereby the slide portions (61) expand the first pressing member (15) via the second pressing member (19), thereby the slide portions (61) are moved in the first radial direction (D1) with respect to the plug member (12).

Abstract: Machining coolant/lubricant is used to operate a piston of a clamping-side coupler by feeding same via a coolant feed passage to a clamping pressure chamber through a first check valve and a clamping pressure fluid passage. The same coolant/lubricant is discharged from an unclamping pressure chamber through an unclamping pressure fluid passage and a second check valve. The resulting movement of the piston downwards brings a clamp member into contact with a workpiece to thereby clamp the workpiece on a table. Thus, a dedicated pressure source for clamping can be dispensed with.

Fluid under pressure actuates the hydraulic means, each element of which is isolated by check valves from the rest of the system so that failure of any one element of the system does not jeopardize the safety of the part being machined or of personnel supervising the machining operations.
