Title: Mixing tool
Inventor: DEITERMANN UDO
IPC: B01F15/00
Filed: 1981-05-02
Abstract: In the mixing tool there are arranged, on a stirrer arm (6) running transversely to a shaft (4), two stirring rods (7, 8) pointing in the direction of the shaft, preferably arranged in the direction of rotation of the mixing tool inclined downwards up to an angle of 45 DEG . This inclination of the stirring rods (7, 8) situated on the outside imposes on the medium to be blended, situated in a container, a turbulence which forces downwards the medium to be mixed and carries it upwards again at the vessel wall. The shaft (4), the transverse stirrer arm (6) and the stirring rods (7 and 8) situated on the outside consist of square bar, which produces a considerable improvement in blending compared to the previously used round bar. <IMAGE>

Patent DE-3125868-A1 (DE)
Title: Air-supply and air-extraction element for subsequent installation into pitched roofs
Inventor: JABLONKA DIETER ING GRAD
IPC: E04D13/17
Filed: 1981-07-01
Abstract: The function of pitched roofs depends mainly on sufficient ventilation. In order to avoid the formation of condensation on the hard roofing or on the trussing sheet, the spaces between the hard roofing and trussing sheet or between trussing sheet and heat insulation are to be provided with sufficient air-supply and air-extraction openings. It is possible to allow for such ventilation openings in the design, but, in practice, this is often neglected and/or the planner or even the builders do not attach enough importance to it. Since a subsequent ventilation, at least of the space between trussing sheet and heat insulation, was not possible hitherto without a large amount of subsequent outlay, the object of the invention is to develop an element which can be installed by slitting the trussing sheet at the eaves plate or the jamb wall and in the vicinity of the ridge from the inside without further secondary operations and, from the outside, for example when the roofs are dismantled, by taking up two tiles. The lateral lugs located on the ventilation element make it possible to push the element into a slit-shaped opening of the trussing sheet, and fasten it there, without additional mechanical fastening. <IMAGE>

Patent DE-3140811-A1 (DE)
Title: Process for the production of high-strength steel cords
Inventor: POIDA MARTIN DIPL ING
IPC: D07B3/02
Filed: 1981-10-14
Abstract: The invention relates to a process for the production of high-strength steel cords by means of high-speed double-twist stranding machines. The aim of the invention is to improve the quality of the steel cords, produced on double-twist stranding machines, in the sector of secondary treatment. The object is, therefore, to develop a process by which the tensile stress caused by the pull is reduced by a specific amount before entry into the secondary treatment devices and newly built-up stress states are not transmitted from one device to the other. In the solution for achieving this object, the cord pulled out of the stranding machine by a double-pulley draw-off is laid in a plurality of turns round the draw-off pulleys, is partially relieved of stress by means of an abrupt reduction in diameter of the draw-off pulleys, in this state is fed to an overwinding device, is thereafter guided again by way of the double-pulley draw-off having the smaller pulley diameter into a straightening stage, and is guided back from this to the double-pulley draw-off and from here, by way of a deflection block, to the winder.

Title: Metal halogen illuminating device having a double-spectral or multispectral lamp arrangement for illuminating printing plates, graphic arts films and other light-sensitive layers of differing spectral sensitivity
Inventor: RUEDIGER JOHANNES
IPC: G03F7/20
Filed: 1982-03-24
Abstract: The invention proposes a lamp arrangement which, in accordance with the spectral sensitivity of the types of layers employed, permits the choice of the type of light which is most effective for the particular layer sensitivity. As exemplary embodiments, the application relating to the invention contains two types of lamp arrangement: the two types of lamp are arranged displaceably in one plane, the chosen type of lamp being moved into illuminating position; the two types of lamp are arranged in a common reflector such that the desired type of lamp can be moved into illuminating position by a rotating device. The possibility of switching the spectrally different lamps via a lamp operating device greatly reduces the costs. At the same time, there is the advantage of using the same copier to expose differing copying or photographic layers in the shortest exposure times.

Title: Process and arrangement for sealing rotating parts from stationary parts of a processing machine for thermoplastics, rubber or the like
Inventor: CAPELLE GERD DIPL ING
IPC: B29C48/50
Filed: 1982-04-01
Abstract: A process and an arrangement are disclosed for sealing rotating machine parts from stationary machine parts in processing machines for rubber, plastics or materials behaving similarly, to be operated at material pressures of up to 500 bar. This aim is achieved by injecting a liquefied, thermoplastic material or the like into the gap between the moving machine parts and cooling these parts on the side facing away from the sealing side as well as heating on the sealing side. This measure ensures a flow direction of the liquified plastic, forced in by a pressure, to the processing chamber and at the same time achieves a sealing effect even with respect to high material pressures.

Title: Electronic adding and subtracting mechanism in BCD 8421 code with decimal display
Inventor: MERKLE PAUL
IPC: G06F7/494
Filed: 1982-06-26
Abstract: The subject-matter of the invention is an electronic parallel adding/subtracting mechanism in BCD 8421 code, in which all numbers are entered BCD coded and in which the first summand is raised from BCD to BCD plus 6 during the adding so that the tetrad adders/subtractors supply the correct result numbers not only during the subtraction but also during the addition. During the adding, the first summand is thus first raised from BCD to BCD plus 6 in that the number 6 (LHHL) is added in each decade by means of activation of a constant. The first summand is thus present BCD-plus-6 coded at the B inputs via the feedback inputs and the second summand is applied BCD coded to the A inputs and added to the first summand which is BCD-plus-6 coded by adding the cardinal number 6 (LHHL). Further summands are added in the same manner; the result number being always BCD-plus-6 coded. At the end, the number 6 (LHHL) must be subtracted again in all decades so that the end result number is not wrong. Subtractions are made without this cardinal number 6 (LHHL). <IMAGE>

Title: Digital circuit for evaluating signal transition sequences
Inventor: HEIDTMANN KLAUS DR
IPC: H03K19/20
Filed: 1983-01-20
Abstract: The invention relates to a digital circuit with a plurality of signal inputs for evaluating the sequence in which signal transitions occur at these inputs. The output signal is activated specifically when a required sequence of transitions is maintained. The circuit is blocked by each incorrect sequence until it is released by a special reset signal. Unlike conventional implementations, the circuit according to the invention is not implemented as a switching mechanism. It is characterised by a minimum outlay in terms of design work and switching arrays. Regardless of the number of inputs, it can make do with one bistable multivibrator. The signal transit times between the inputs and the output are extremely short. The circuit is of modular design and can thus be extended in simple fashion by additional inputs. To evaluate more complex signal transition sequences, a plurality of circuits according to the invention can be interconnected in different ways.

Title: Process for producing an elastic, double-sided adhesive tape
Inventor: KRUEGER GERHARD
IPC: C09J7/02
Filed: 1983-02-04
Abstract: For producing an elastic, double-sided adhesive tape, a core layer and two outer layers based on natural rubber are prepared and treated on a rotary vulcanising machine, the rubber mixture of the core layer being completed vulcanised and firmly bonded to the two outer layers. The rubber mixtures of the outer layers contain no accelerator; however, the complete vulcanisation of the core layer affects the adjacent region of the outer layers, so that a partial vulcanisation and thereby the required firm bond results there, whilst the exposed regions of the top layers remain unvulcanised and tacky and guarantee good adhesion with direct outer layer/outer layer contact.
