Patent DE-3022564-A1 (DE)
Inventor: WINTELER WERNER
IPC: B02C25/00
Filed: 1980-06-16
Abstract: According to the method, a mechanical control signal is generated according to the product supply for the control of a metering valve (9). To obtain powerful control operation with a high precision and reliability and of a simple and compact construction, the mechanical control signal is first transformed into a pneumatic signal which is transmitted as an input signal to a servocontrol (41) for regulating the product supply and/or to a servocontrol (18) for the start up or shut down of the milling cylinder. A device specially adapted to this method is a cylinder mill which comprises a mechanical signal transmitter (13, 15) operating a pneumatic regulating valve (17) of which the output is connected to the input of a servocontrol (18) actuating the metering valve (9) and/or the start up and shut down of milling cylinders (1, l', 2, 2').

Title: Sausage filling machine with device for forming sausage ends
Inventor: SCHNELL KARL
IPC: A22C11/10
Filed: 1981-02-06
Abstract: Devices (1) for forming sausage ends are normally arranged downstream of sausage filling machines. In such devices, the filled sausage strand which is discharged by the sausage filling machine is divided up into individual pieces, i.e. sausages (3, 4). There is a connection piece (6) between the two units. If a cutting-off device (7) is then mounted, according to the invention, behind the sausage end-forming device (1) in the direction of movement (8), through which cutting-off device (7) the string of sausages must necessarily pass, the said devices (1 and 7) can be matched to one another in such a way that individual sausages or, for example, pairs of sausages, are cut off the string of sausages. The cutting-off device (7) can be driven by the sausage filling machine or, more advantageously, by the sausage end-forming device (1), so that no separate drive motor is required. The said device (7) has at least one, but preferably two, rotating cutting blades (18 and 19) which each interact with a cutting counterpiece (20, 21). Synchronous operation is achieved with the aid of gear wheels (23 and 24) which are mounted so as to be fixed in terms of rotation on the shafts (25 and 36 respectively) of the cutting blades and the cutting counterpieces respectively. <IMAGE>

Title: Cellular wheel sluice with lift-out cellular wheel for suction-pneumatic conveying systems
Inventor: KILLICHES WALTER ING GRAD
IPC: B65G53/46
Filed: 1981-04-15
Abstract: Such cellular wheel sluices, used primarily for discharging a conveyed product out of the vacuum region of a conveying system into the atmospheric region, require the cellular wheel to be adjusted from time to time because of the inevitable wear on their housing, in order to minimise the increase in the leakage air losses through the gap and the consequent decline in performance of the conveying system. This adjustment of the cellular wheel, or a change of its location and possibly also of its orientation, results, in the conventional design, in impairment of the tooth engagement conditions in the toothed wheels of the transmission between drive motor and cellular wheel. A force transmission for the cellular wheel drive is proposed, in which a resilient intermediate member (240) is inserted which automatically compensates the relative changes in the position or orientation of drive members (239, 241) occurring as a result of adjustment of the cellular wheel (202) and so prevents adverse effects on the drive and its structural elements. <IMAGE>

Title: Steering of a model rowing boat
Inventor: WEDEMEYER ERWIN
IPC: A63H23/00
Filed: 1981-07-29
Abstract: The invention relates to the steering of a model rowing boat by alternate use of the oars. A rowing boat can be steered by virtue of the fact that one oar is not used or is only partly used, depending on the intensity of the change of direction, while full rowing is continued with the opposite oar until the boat has obtained the desired direction. In a model rowing boat, this operation has to be carried out by a mechanism with remote control. To this end, each oar is mounted with the oar pin (rowlock) on a bell-crank lever, whose part projecting into the boat is connected via a linkage to the lever of the steering servo. During a steering impulse, the vertical position of the oar on whose side the boat is to be steered is changed from full use to idling, while the opposite oar continues to be used at full immersion depth until the steering impulse ends or the desired direction is obtained.

Patent DE-3214223-A1 (DE)
Title: Axial fan
Inventor: BECKER WALTER
IPC: F04D29/36
Filed: 1982-04-17
Abstract: The invention relates to an axial fan with rotor blades adjustable in operation, the blade shafts of which are each supported and held in through bores of an annular carrier. In order to be able to transmit the high centrifugal forces occurring in axial fans of this type, very expensive bearing and retaining devices for the rotor blades with a high manufacturing cost have hitherto been known. In order to achieve cost-effective manufacture with simultaneously high operating reliability, it is proposed according to the invention that the through bores be formed without relief turning and that a retaining element be arranged in each through bore in the area of the outer circumference of the carrier. The known retaining element is connected to the carrier and undertakes the support of the axial bearing. <IMAGE>
