Abstract: The invention relates to such a device, in which an eccentric shaft is provided which is mounted in a rotatable manner in the side frame of the machine and accommodates in a rotatable manner a pre-gripper shaft, which is under the influence of a cam, the eccentric shaft being firmly attached to a gearwheel which is in constant engagement with a drive gearwheel rotating with the printing cylinder. 
<??>In order to provide, in a device of the described nature, interlocking and consequently co-operating drive parts and a co-axial arrangement of the drive shafts and driven shafts to introduce the additional movement, which is superimposed upon the continuous rotation of the pre-gripper cam as it lifts out, the eccentric shaft (14) is rotatably mounted in a housing shell (15) on the side frame (5) and in the opposite side-frame of the machine. The pre-gripper shaft (16) is under the influence of triple cam discs (9, 10, 11), attached to the side frame (5) of the machine, via cam followers (6, 7, 8), which are attached to a connecting rod (3), which bears in a rotatable manner on the gripper shaft (16). At a hinge point (17) on the connecting rod (3) is articulated a trailing lever (4), which is articulated at a further hinge point (18), eccentric in a gearwheel (19).

Patent DE-3632926-A1 (DE)
Title: Method and apparatus for damping the pressure peak which occurs at the end of the die-filling phase in die-casting machines
Inventor: KLENK WALTER
IPC: B22D17/32
Filed: 1986-09-27
Abstract: The invention relates to a method for damping the pressure peak which occurs at the end of the die-filling phase in die-casting machines, there being arranged between the piston rod of the driving piston and the piston rod of the casting piston a hydraulic damping device, the damping space of which is closed off by a control piston through which there is no flow in the case of damping and which does not have to move in the opposite direction to the piston rod of the casting piston in order to open the control edge. It is here that the invention has set itself the object of shortening the operating time of the control piston to a minimum. According to the invention, this purpose is served by the proposal that the force on the control piston (4) required to close the control edge (11) is provided by the atmospheric pressure, which takes effect by virtue of a vacuum in the damping space (9) and storage space (10). The corresponding device is characterised in that the force for the opening movement of the damping device is achieved by means of springs (29) which are arranged between the housing (28) and a stop plate (13) of the damping piston (3), as a result of which the vacuum which arises in the damping space (9) sucks the hydraulic fluid out of the storage space (10) via the non-return valve (5) and hence, at the same time, moves the control piston (4) until the control edge (11) separates the storage space (10) from the damping space (9). <IMAGE>

Title: Rotary drum for carbonising wastes with exclusion of air
Inventor: VOLLHARDT FROHMUT DIPL ING
IPC: C10B1/10
Filed: 1987-03-03
Abstract: The rotary drum according to the parent patent is provided with a self-supporting, freely expanding heating tube register which has no fixed joint to the rotary drum cell. The heating tube register system can be replaced as a whole. Owing to the rotary motion of the drum, the lower region of the register is always in the waste, while the upper region of the heating tube register does not come into contact with waste materials. This can cause differential expansions in the heating tube. In the heating tube register (8) according to the invention, the heating tubes (9, 11) are spirally bent (23), preferably in the middle region of the rotary drum, and in particular in the form of half a spiral, 11/2 , 21/2  spirals and so on. The rotary drum is suitable for the carbonisation of waste materials of any type. <IMAGE>

Patent DE-3733077-A1 (DE)
Title: Alternating current arc furnace
Inventor: BREHLER ROBERT
IPC: H05B7/144
Filed: 1987-09-30
Abstract: Known alternating current arc furnaces cause power and reactive power fluctuations and highly differing loads on the network phases. This results in voltage fluctuations in the supply network and thus so-called light flickering and high noise levels at the furnace itself. Direct current arc furnaces do not have these disadvantages but are, however, substantially more complicated (costly). In an alternating current arc furnace, a converter (13, 14, 15, 19) is arranged between the furnace transformer (7) fed from the alternating-current network (8) and the electrodes (4, 5, 6), which converter transforms the mains frequency to a lower-frequency value for the electrode currents. The arrangement makes it possible for an existing alternating current arc furnace to be operated in the direct current manner as a result of relatively minor modification measures and to offer the same advantages as the direct current arc furnace but with considerably less technical complexity. <IMAGE>

Title: Pneumatic or hydraulic swivel drive for fittings
Inventor: FRITZ GEORG
IPC: F15B15/08
Filed: 1988-08-12
Abstract: The swivel drive is based on a piston (6) to be actuated pneumatically or hydraulically, the piston movement being converted into a torsional movement by an oscillatory spindle (22). The cylinder housing is produced from two identical cast or forged parts (1, 2) which consist of cylinders closed on one side and are joined together centrally without an intermediate part. The piston is in principle designed as a double piston. Arranged in the connecting part (7) of the double piston (6) are spring chambers (20) open on one side and extending over the entire connecting part (7). These spring chambers are provided for accommodating restoring springs (21) which, upon removal of the piston pressure plate (9) (cover plate), are supported on the one side against the inner surface of the housing end wall (3) and on the other side against the inner surface of the piston lying behind the spindle (22). <IMAGE>

Title: Pulse-edge-controlled register
Inventor: GREISLE GERHARD DIPL ING
IPC: H03K5/133
Filed: 1988-09-01
Abstract: The pulse-edge-controlled register consists of a pulse former stage (PF) and single-stage memory cells (SZ). On the occurrence of the edge of the clock signal (TS), the pulse former stage (PF) delivers a clock pulse (CKI) of such a width that the data (D) to be stored are transferred securely into the memory cells (SZ). The memory cell (SZ) consists of a transfer gate and two back-coupled invertors. The data, and the clock pulse, are present at the transfer gate. The transfer gate is switched on by the clock pulse (CKI), and the data are transferred to the back-coupled invertors. The data are stored there only when the clock pulse is no longer present at the transfer gate. This gives a register which is controlled by the pulse edge of a clock signal, and which has single-stage memory cells. <IMAGE>
