The invention relates to a respiratory device for keeping a patient breathing artificially or support his or her breathing naturally. Said respiratory device comprises an air inlet, an air source, and at least one proportionally adjustable control valve. The control valve is provided with a housing (11) and a rotary valve (12) which is arranged in the housing so as to be twistable about the longitudinal axis thereof and which allows through-holes (11d) of the housing (11) to be entirely or partially closed by twisting the rotary valve (12). The rotary valve (12) and a corresponding support surface (11f) of the housing (11) have a conical shape, the support surface (11f) cooperating with the rotary valve (12). The through-holes (11d) are disposed in the area of the support surface (11f).
摘要:
A method and device for producing printed products wherein first primary products are supplied, respectively, fold first to successive, uniformly-spaced pockets disposed transversely to a conveying direction at a beginning of a first segment of a production path formed by feeders. Subsequently, the first primary product in each pocket is grasped at a protruding gripping edge and opened for insertion of a partial product or enclosure. A further primary product is supplied, respectively, to the successive pockets on a further segment adjoining the first segment of the production path for producing a further printed product, including partial products or enclosures, in the successive pockets.
摘要:
A method and an apparatus for collecting or gathering printed products to form final printed products, such as newspapers, magazines, brochures and/or books, wherein the printed products are moved along supply lines and are supplied to one or more processing locations. At least two of the printed products intended for forming a final printed product are combined at a collecting point provided in a supply line and the combined printed products are further transported together.
摘要:
On a turret (30) which can be driven in rotation about a central axis (A), a plurality of expanding mandrels (42) are arranged all around the central axis (A). They are each essentially composed of a supporting member (44) which is secured to the turret (30) and defines an expanding-mandrel axis (B), a plurality of segmental bars (52) which are arranged all round the expanding-mandrel axis (B) and are guided on the supporting member (44) for radial adjustment, and a wedge (70) which is displaceable along the expanding-mandrel axis (B) to spread the segmental bars (52) apart. The wedges (70) are displaceable in succession, by a common actuating member, during one revolution of the turret (30). The actuating member is a central cam member (18) on which each of the wedges (70) is supported at least during a portion of each revolution of the turret (30) corresponding to the distance between two adjacent expanding mandrels (52).
摘要:
For welding tongues (12) onto sheet-metal parts (10), particularly tear-open can parts, a welding machine having at least one pair of welding electrodes (62, 63) is provided. The sheet-metal parts (10) can be moved through the machine steps between the welding electrodes (62, 63), one behind the other, by a sheet-metal conveyor (15) and be located in a defined position by a positioning device (17). The tongues (12) can each be placed against a sheet-metal part (10) between the welding electrodes (62, 63) in synchronism with the working cycle of the sheet-metal conveyor (15) by a tongue conveyor (18).
摘要:
A transport system (1) is provided for removing individual signatures (2) from a transport flow. The system includes grippers (3) which are attached in substantially equal distance therebetween to an endless loop pulling means for holding the signatures (2), and an actuating device (11) causing the grippers (3) to open, with the actuating device (11) displacing a lever arm (13) which is connected to the moveable gripper element (10), to a laterally spaced-apart guide rail (12).
摘要:
In a device for processing printed products supplied to a stacking device, the printed products are picked up at a delivery of a printing machine or a printed product processing machine by a transport device and are transported in a suspended position on a transport path to a transfer device upstream of a stacking device. The stacking device is a unit detachable from the transfer device and connectable alternatingly to the transfer device connected so as to effect conveying of the printed products to the printing machine or the printed product processing machine.
摘要:
A method and an apparatus for manufacturing printed products by insetting at least one subproduct and/or inserts into a main product, wherein at least the main products are grasped at the delivery of a printing machine by revolving gripping members of a conveying unit provided with an intermediate storage arrangement for inserting and delivering products, wherein the products are conveyed on conveying paths to an insetting machine formed of revolving insetting pockets, and wherein the products are taken up at the delivery of the printing machine by a first conveyor of the conveying unit connected to the insertion side of the intermediate storage arrangement and are transferred to a second conveyor of the conveying unit connected to the delivery side of the intermediate storage arrangement. The products grasped at the folds thereof are selectively transferred in front of the intermediate storage arrangement from the first conveyor with the folds facing forwardly on a direct transfer path to the second conveyor.
摘要:
An intermittent or stepping drive has a first rotatable member (20), which is driven by a driving shaft (12), in engaging relationship with a second rotatable member (30) from which a driven shaft (22) is driven whereby a continuous rotation of the first rotatable member (20) is converted into an intermittent rotation of the second rotatable member (30). One of the two rotatable members (20,30) is connected to the associated shaft (12,22) by a clutch (40) which is associated with a retaining member (50) that exerts thereon a retaining force (E) acting in an engagement sense. One of the shafts (12,22) is associated with a control device (60) which controls the retaining force (E) depending upon the angular position of rotation of the shaft. The control is suitable for the actual applications of the stepping drive of the type in which the clutch in each drive phase transmits a moment that is just as large as the sum of the acceleration moment, the useful moment and the friction moment, which occur in the respective driving phases when the drive is not disturbed. If this sum should be exceeded by a disturbing moment, the clutch permits a relative rotation of the rotatable member in question with respect to the associated shaft as well as when the disturbing moment is small in relation to said sum of the moments.
摘要:
The can member (10) is provided with a pair of scorings (16) which define a tear-off strip (18) laterally. A tongue (20) produced as a separate sheet-metal member is welded onto the tear-off strip (18) in a welding region (42) at one of its ends. Between the welding region (42) and the free end (32) of the tongue (20), a starting scoring (30) extends over the tear-off strip (18). The starting scoring (30) extends substantially transversely to the lateral scorings (16) only in a central region of the tear-off strip (18) and extends away from the free end (32) of the tongue (20) in the vicinity of the two lateral scorings (16). The welding region (42) covers the starting scoring (30) in the vicinity of each of the two lateral scorings (16). As a result, care is taken to ensure that a tearing open operation can be reliably initiated by rolling up the tongue, substantially regardless of inaccuracies in manufacture.
