Patent DE-3118786-A1 (DE)
Title: Apparatus for assembling or palletising articles
Inventor: VILLANUEVA ELISEO HERRANDO
IPC: B65G65/00
Filed: 1981-05-12
Abstract: An apparatus for assembling or palletising articles has a transfer table which can be reciprocally moved by means of a trolley along a horizontal girder of a transverse bridge and can be tilted over an endless conveyor belt. The object is to provide an apparatus of this type with which articles which are combined in groups of four or more articles can be conveyed in palletised form from an upstream device. This object is achieved in that the transfer table has a horizontal surface for receiving four articles supplied from an upstream device, e.g. a press, in a co-planar arrangement which is preferably formed by two adjacent, rectangular panels for receiving two articles each. A row of stops, in each case fixed on a shaft, is arranged along one long side of each panel, these stops supporting the two articles placed on the respective panel during the tilting of the transfer table into a substantially vertical position. The stops are retractable, in order to release the articles, by a simultaneous actuation of the two shafts by means of a common pneumatic or hydraulic cylinder, so that the two articles which are positioned lower in the tilted position of the table can be directly deposited on a pallet or platform which is advanced by steps by means of the conveyor belt, while the two upper articles can be transferred by means of an assigned vertical conveyor onto the same pallet or platform.

Title: Method of cleaning the trough of a pulp grinder, and grinder for carrying out this method
Inventor: SALAKARI HANNU
IPC: D21B1/24
Filed: 1981-05-12
Abstract: Method of cleaning the pulp trough of a pulp grinder for the periodic emptying of chips and slivers collected in a trough (6) located under a rotating grinding stone (3) and dammed by an overflow flap (8). The flap is shifted from its damming position into an emptying position, where the dammed pulp flows out of the trough taking the above-mentioned collected chips and slivers with it. After this the flap is shifted back into the damming position. Here, the pulp in the trough is used for flushing the chips and slivers so that the trough can be cleaned without interrupting the grinding process and without the pressure in the grinding chamber being relieved. The grinder for carrying out the method is provided with a damming flap (8) which is mounted in the pulp trough in such a way that it can be shifted between a damming position and an emptying position and permits pulp, chips and slivers to flow out of the trough. The flap is coupled to a drive device (12) in order to shift the flap. The drive device is arranged on a control member (16, 17) in order to control the function of the device as a function of a predetermined program. <IMAGE>

Title: Circuit arrangement for detecting and distinguishing frequency-determined remote control signals
Inventor: WEBER JOSEF
IPC: G08C19/26
Filed: 1981-10-13
Abstract: In a circuit arrangement for detecting and distinguishing frequency-determined remote control signals, particularly pulse series of various different frequencies in infrared remote controls, a switching mechanism can be operated by each pulse obtained from the received signal in a fixed ratio to its frequency for detecting the remote control signals and dividing them into channels, as long as the voltage across a capacitor which can be charged up via the switches of the switching mechanism with different currents for each step which rise in the order of switching, and the discharge of which is caused by each of these pulses, has not reached a particular threshold value before the arrival of the next pulse, the reaching of this threshold value due to the interaction of capacitor charging current and capacitor capacitance over the time required for this being a measure of the frequency of the pulse sequence, here for the transgression below the upper frequency limit of the receiving channel provided for the existing switching position, and thus initially indicates the selection of the correct frequency channel by means of the position of the switching mechanism reached during this process. That the switching mechanism can be brought into a switching position which occurs in the order of switching between the two switching positions, one of which causes the charging of the capacitor with the highest and the other one of which causes the charging of the capacitor with the lowest of the currents possible by means of the switchable switching positions, if their positions were to include the switching mechanism, or into one of these two switching positions if the voltage across this capacitor reaches a further threshold value, the reaching of this threshold value due to the interaction of capacitor charging current and capacitor capacitance over the required time being a measure of the frequency of the pulse sequence, here for the transgression below the lower frequency limit of the receiving channel intended for the existing switching position, and thus indicates at least one missing pulse in the pulse sequence, which is otherwise regular for a remote control process, or the ending of the pulse sequence due to the non-arrival of a pulse before this threshold value is reached. <IMAGE>

Filed: 1981-11-21
Abstract: What is proposed is a hydraulic control device (10) for regulating the lifting mechanism on tractors and the like, which, with fully hydraulic signal processing, possesses a rear actuation device (36), by means of which the lifting mechanism is movable out of any position. From the bridge connection (26) having the actual-value and desired-value transmitters (31, 34) and the regulating valve (14), a parallel bridge branch (35), in which a second desired-value transmitter (37) for rear actuation is inserted, branches off to the tank (21) upstream of the bridge resistors (28, 29, 33, 34). It has oppositely working resistors (38, 39), the intermediate pressure (41) of which can be fed via a switching valve (44) to one end (43) of the bridge diagonal (25), the switching valve (44) having a catch device (51) controlled as a function of a differential pressure. The rear actuation device (36) can be moved out of any position of the lifting mechanism, undesired movements of the lifting mechanism at switch-on being avoided. <IMAGE>

Title: Oscillating piston internal combustion engine with star-shaped, decentrally arranged single piston shafts, cam-crank disc and annular race valve control with cylinder shut-off
Inventor: BAUMANN KARL DR
IPC: F02B53/02
Filed: 1982-03-25
Abstract: At least two single oscillating pistons acted upon on one side serve as basic elements in the energy conversion function. These are arranged in a star-shape about a central shaft in a fixed housing, the piston shafts being located in a position, relative to the central shaft, which is remote from the hub. With regard to the overall volume, the total mass and the partial masses to be accelerated this solution is more advantageous compared to the reciprocating-piston in-line engine, but nevertheless falls short of the values expected of internal combustion engines with multiple oscillating pistons. This partial disadvantage is more than compensated for by performance- related advantages: favourable points of application for the torques lead to a strong and flexible overall torque. In addition there is the tight power cycle sequence resulting from the interaction of oscillating arms as work transmitting drive elements with a cam-crank disc for transformation of the oscillation movements and power transmission. All torques are introduced into the compact and low-oscillation crank disc in one plane of rotation, these torques acting alternately in sequence offset by 180 DEG . The omission of an intermediate gear to the valve control constitutes a further advantage, since the valve mechanical action is directly operated by a rotating component connected to the crank disc. Finally owing to the process characteristics a load-related cylinder shut-off is possible even in the case of a unit with less than six cylinders.

Title: Cup piston for hydraulic or pneumatic cylinders in motor-vehicle disc brakes
Inventor: THIEL RUDOLF
IPC: F16D65/84
Filed: 1982-07-20
Abstract: The invention relates to a cup piston for hydraulic or pneumatic cylinders in motor-vehicle disc brakes, with a plastic piston body which is also able to cope with larger thermal and mechanical loads inside a vehicle brake and yet requires no undue expense during manufacture. To this end, the invention provides for an annular sheet-metal protective cap to be allocated to the annular actuating end face, which annular sheet-metal protective cap is connected to the plastic piston body in a positive-locking manner. Provision is made in particular for the positive-locking connection to be formed by a snap connection between the piston body and an axial extension of the sheet-metal protective cap. Furthermore, a method of manufacturing the cup piston is proposed in which the annular sheet-metal protective cap is connected in the positive-locking manner to the plastic piston body, in particular snapped onto the latter, in the heated state before the disappearance of the elastic deformability due to completion of polymerisation.
