Patent DE-3049919-A1 (DE)
Inventor: ZUCKER FRIEDRICH J DIPL ING
IPC: B29B13/02
Filed: 1980-03-11
Abstract: Appts. for melting materials possessing low thermal conductivity comprises a heated, revolving disc, with an upstanding wall revolving together with it. Openings at the bottom of the wall permit discharge of the centrifuged and heated material. The revolving disc is heated at least to the fusion temperature of the material, the revolving wall itself forms the upstanding rim of the disc, while the disc together with wall revolves in a stationary housing possessing an outlet for the melted material. Used in particular for the melting of thermoplastics, where the low conductivity leads to a risk of the material becoming overheated at the zone in contact with the heating surface. By placing the material on a heated, revolving disc, as soon as the surface of the material grains or blocks becomes melted the block slides centrifugally outwards, and therefore does not stick to the disc and become overheated.

Title: Protective-earth contact plug with lever operation
IPC: H01R13/633
Filed: 1981-01-19
Abstract: The invention relates to electrical plugs for insertion into plug sockets. Since tightly seated plugs can be withdrawn from a plug socket only with difficulty, they are frequently just pulled out of the plug socket by the conductive cable, which in many cases leads to the cable, plug and plug socket being damaged. Only one plug has been designed which prevents this damage. This plug was provided with a pin which emerges on the end face between the positive pole and the negative pole, and with a lever which is located on the rear face, is connected to the pin and can pivot through 90 DEG . If any attempt is now made to withdraw the plug from the plug socket on the lever or on the cable, the ejection device comes into operation at the same time. As a result of this ejection device, the plugs can now be ejected from plug sockets very easily, without any damage and using only one hand. <IMAGE>

Title: Pressing-out device for handling a pulpy solids suspension
Inventor: KOCH KLAUS DIPL PHYS
IPC: B30B9/12
Filed: 1981-05-12
Abstract: A pre-handling station for a pressing-out device is disclosed for a pulpy solids suspension, such as for example sewage sludge, paper pulps or other liquid/solid mixtures. The pre-handling station is to work continuously, have a high receiving capacity, be operable with low energy costs as well as simple and robust in construction and working method. This aim is achieved by the arrangement of at least two exchangeable perforated-sheet containers on a receiving rotary table, under which there is arranged coaxially a stationary disc with an eccentric opening, which corresponds in its cross-sectional area to the size of the cross-sectional area of one perforated-sheet container as well as to the cross-sectional area of a filling opening of the pressing-out device. As a result of the timed rotation of the receiving rotary table, in each case one container is moved under the filling nozzle, filled and rotated further. The container contents are pre-dewatered by sinking the solids content and running off the liquid from the holes of the container, for example by 5-10% and finally passes over the filling opening of the actual pressing-out device. As the perforated-sheet containers are open at the bottom, emptying takes place by gravity. On the next rotation cycle, the following perforated-sheet container is filled and the preceding container is emptied by displacement over the filling opening, as a result of which a continuous pre-dewatering of greater receiving capacity is achieved.

Title: Heat-insulated hollow block and process and device for the production thereof
Inventor: ADAMS ENGELBERT
IPC: B28B11/04
Filed: 1981-06-03
Abstract: A description is given of a heat-insulated hollow block and a process and a device for the production thereof. The hollow block is distinguished in that its individual block chambers have a heat-insulated filling consisting of mineral fibres which have been introduced into the hollow-block chambers either mechanically by plugging or pneumatically by using superatmospheric pressure and/or subatmospheric pressure. A heat-insulated hollow block of this type can not only be produced automatically and cost-effectively, but it can also ensure an extremely advantageous heat insulation. The device for producing the hollow block and for carrying out the production process has in each case, for filling the hollow-block chambers, a metering mould from which the metered mineral-fibre quantity is introduced into the hollow-block chambers either by a plugging ram or by acting on it with compressed air. <IMAGE>
Patent DE-3122129-A1 (DE)
Title: Device for improving the movement of crane trolleys, in particular on container cranes
Inventor: SEDLMAYER FRANZ
IPC: B66C11/16
Filed: 1981-06-04
Abstract: Cranes with a wide swing (reach) are often equipped with a remote-controlled main trolley and an intermediate trolley which is moved along with the latter and via which at least one working cable for operating the main trolley is guided. The drive cables connecting the trolleys to one another and to the drive station extend in two parallel planes symmetrically relative to the trolley centre. In particular in container mode, the cables in the parallel planes are often subjected to an uneven loading. For preventing the oblique positioning of the trolleys, which results from this, the intermediate trolley is made of two side parts which can be moved towards one another along their guide track in the travel direction and the opposite direction. The intermediate trolley drive cable sections issuing from the side parts are in this case held jointly on a compensation unit on the side remote from the main trolley and can be pivoted with this unit about an axis perpendicular to the direction of travel and the opposite direction. By displacing the side parts relative to one another, a force balance is effected in the associated cables. <IMAGE>

Title: Set of continuous forms
Inventor: FISCHER WERNER
IPC: B41L1/32
Filed: 1981-10-22
Abstract: The invention relates to a set of continuous forms, in which, conventionally, all the layers are provided at both their longitudinal edges with guide perforations on edge strips. In narrow transporting rollers, a displacement of the individual layers and compression take place which continues over the set of continuous forms such that a different image is printed on different layers and also the layers can slip from the pins of the pin feed platens transporting them. Furthermore, the edge strips constitute an excessive use of paper since they cannot be used for the form image and are often separated as waste. To avoid the disadvantages mentioned, it is proposed according to the invention to provide only one of the layers (2) with edge perforations (12). <IMAGE>

Title: Indexing mechanism for a chain machine
Inventor: SCHULZKI JOACHIM DIPL ING
IPC: B23Q7/03
Filed: 1981-10-30
Abstract: Indexing mechanism for a chain machine, in which the upper strand performs an indexing movement and the lower strand of the chain (4) performs a continuous movement, this being achieved by a chain drive and a reciprocating chain carriage (1). The drive is provided via two cams (10, 14) arranged on a shaft (9), one cam (10) transmitting the indexing movement to the chain wheel (2) via a modified worm and roller drive and the other cam (14) transmitting the reciprocating movement to the frame (3) of the chain carriage (1). The sequence of motions of the chain (4) and the frame (3) is based on the law of motion of a simple sinusoid, as a result of which the intermittent motion of the chain (4) is completely shock- and jerk-free. The indexing mechanism has the following advantages: given a plurality of machines, for example within a production group, with chains of the same chain pitch but with chain lengths of arbitrary size and the same step spacing, one version of the indexing mechanism (7) can be used to provide the drive. The chain can be guided in any desired manner. <IMAGE>

Patent DE-3200753-A1 (DE)
Title: Circuit arrangement for setting the speed of a universal motor
Inventor: SCHOTTEN HENNO DIPL ING
IPC: H02P25/14
Filed: 1982-01-13
Abstract: In a circuit arrangement for setting the speed of a universal motor (1, 2) to different speed ranges, the field winding (2) is provided with a tap (4). The field connection (4) can be connected via a triac (5) and the free end connection (13) of the field winding (2) can be connected via a triac (7), to a common supply line (6). When the tap (4) is driven, a reduced field excitation and hence a higher basic speed are thus achieved. In order in this case to achieve a feedback signal tending to zero volts, during each half-cycle of the supply current, at one input (17) of a control circuit (12) when one of the two triacs (5, 7) is triggered, two pairs of diodes (14, 15; 20, 21), connected in the reverse direction to one another, are connected between the tap (4) and the end connection (13), from whose connection points a connection to the input (17) is created via diodes (18 and 23 respectively). When one of the triacs (5, 7) is triggered, the control potential at the input (17) is then switched through, in each case via a portion of the diodes, to the supply line (6) which simultaneously forms the reference potential for the control circuit (12). <IMAGE>

Title: Method for controlling the position of a control element of a combustion engine influencing a fuel-air mixture
Inventor: BOCKELMANN WILFRIED DIPL ING
IPC: F02D11/10
Filed: 1982-02-17
Abstract: In a method for controlling the position of a control element of a combustion engine influencing a fuel-air mixture by means of an electronic accelerator pedal, the electric motor-driven control element is adjusted according to the operating state at the respective rate of adjustment which is necessary to ensure that engine operation in characteristic ranges favourable to performance and/or consumption is brought about or engine operation in unfavourable characteristic ranges is avoided. Various operating parameters are recorded, such as the reference and actual values of the engine speed, the rates of change of the reference and actual values with time, the difference in speed between the reference and actual values and the intake pipe vacuum, in order, with the aid of these values, to determine the particular most favourable rate of adjustment for the control element from stored actuating characteristics. At the same time, restriction of the minimum intake pipe vacuum is used in order to avoid engine characteristic ranges particularly unfavourable to consumption. In one practical embodiment a minimum rate of adjustment Vmin, a maximum rate of adjustment Vmax and a variable rate of adjustment v(A) dependent on the particular speed difference are provided as rates of adjustment.
