Title: Communications unit for coupling microcomputers
Inventor: HEIDTMANN KLAUS DR
IPC: G06F15/167
Filed: 1983-11-05
Abstract: The invention relates to a circuit for coupling a plurality of microcomputers, for the purpose of communication and cooperation. Said device consists of a multiport communications memory and an access controller, which prevents access conflicts. In contrast to conventional implementations of the coupling of a plurality of microcomputers via a single line by means of serial data transmission (for example in local networks), or close hardware coupling of a plurality of processors via a common bus, the invention implements the coupling of the microcomputers in a parallel broadband manner via an addressing and data bus, by means of the connection of a multiport memory to an integrated access controller (port controller). In this case, the hardware cost required is minimal. The circuit is of modular construction and can very easily be matched to the required conditions, especially by expansions of the communications memory or increasing the number of connections for computers. The loose coupling by means of the communications unit prevents mutual interference between the connected microcomputers and saves costly synchronisation measures.

Title: Method for installing a new tank on a tank waggon
Inventor: PIETROWSKI EDMUND ING GRAD
IPC: B61D5/06
Filed: 1984-06-08
Abstract: Tank waggons with a tank which is installed in different ways are used for rail-bound transport of different freight, in the case of two-axle tank waggons the tank usually being welded in the underframe consisting of two continuous longitudinal bearers and head stocks. In tank waggons of this kind of the monoblock design, re-equipping a tank waggon with a new tank, for example for transporting a different freight, was previously so complicated and thus uneconomical that a new tank waggon could almost be produced with the same effort. By means of the method according to the invention, an economical re-equipment of a tank waggon with a new tank is to be made possible. This is achieved in that the remaining tank base of the tank which, in the region of the head stocks, is flush with the stepped plate and separated in the region of the longitudinal bearers, at a distance from said plate, bears the receptacle for adding on a new tank.

Inventor: POELLATH HELMUT
IPC: F02M61/16
Filed: 1984-08-02
Abstract: A spring bracket (6) which is bent essentially into a U-shape is used to connect an injection nozzle (3) to a coaxially arranged connecting stub (1) of an injection line. This spring bracket (6) has a web (7) which runs transversely with respect to the longitudinal extent of the injection nozzle (3), and flaps (12) which are bent at right angles thereto and engage in a groove (13) in the injection nozzle (3). In order to attach the connecting stub (1), said stub (1) has a radial projection (10) which can latch into corresponding perforations (9) in the limbs (8) of the spring bracket (6). In order to be able to insert the injection nozzle (3) with the pushed-on spring bracket (6) into the connecting stub (1) as a structural unit, the limbs (8) of the spring bracket (6) are bent outwards. In consequence, guide surfaces are produced for the radial projection (10) of the connecting stub (1), so that the production of the connection is considerably simplified (Fig. 2). <IMAGE>

Title: Installation for the manufacture of chipboards, fibreboards and the like
IPC: B27N3/16
Filed: 1984-10-19
Abstract: Installation for the manufacture of chipboards, fibreboards and the like, with spreading machine unit, platen press unit and conveyor unit. With the spreading machine unit, a continuous press-material mat can be spread onto a spreading band section, moving continuously and at constant speed, of the conveyor unit. The press-material mat can be split up into mat sections by means of a cut-off saw. The platen press unit has a single-daylight platen press through which an endless press band moving in cycles with dwell time during the press operation is passed. Adjoining the spreading band section of the conveyor unit is an accelerating band section which is connected via a transfer nose to the press band. The conveyor unit has a standard, endlessly revolving conveyor belt which forms both the spreading band section and the accelerating band section. The acceleration speed of the accelerating band section can be produced by superposition of the drive speed with the speed of a reciprocating gap chassis, which forms a transfer gap, as well as a reciprocating movement, adapted thereto, of an accelerating chassis with two further 180 DEG deflection rollers. For this purpose, the conveyor belt is run behind the transfer nose to the accelerating chassis as well as from there via its drive drum. <IMAGE>

Title: Hot-rolled and thermally work-hardened reinforcing steel
Inventor: WELFLE KURT DIPL ING
IPC: C22C38/44
Filed: 1985-01-25
Abstract: The invention relates to hot-rolled, thermally work-hardened reinforcing steel having a minimum yield strength of 500 MPa and universal suitability for welding in the dimensional range of 6 to 32 mm nominal diameter. The aim of the invention is the processing of scrap contaminated with Cr, Cu, Mo and Ni to give high-quality reinforcing steel. The object is to indicate an alloy composition which allows the alloy contaminations to be utilised for improving the use value in place of the addition of Si and Mn, hitherto provided in industry. The object is achieved by deviating from the standard prescription of an alloy tolerance for Si and Mn and lower permissible limits for Cr, Cu, Mo and Ni and, instead, weighting and limiting the total alloy influence of Si, Mn, Cr, Cu, Mo and Ni and allowing large tolerances for the individual elements, it being permissible for individual elements to be present in any desired quantity and combination within the new limits, while adhering to the value for the alloy equivalent and hence also for the total alloy influence on the yield strength, in accordance with the claim.

Title: Arrangement for disconnecting loads
Inventor: BEER RUDOLF
IPC: H01H3/00
Filed: 1985-03-13
Abstract: The invention relates to an arrangement for the two-pole or multipole connection and disconnection of loads, preferably the heating of washing machines. Slides which are in the form of plates and support the contact links of two separate contact systems are used for this purpose. The slides engage in one another in the form of fingers on the side facing a common restoring spring, so that both slides are acted on simultaneously by the common restoring spring. Restoring springs which are allocated to each individual slide are positioned obliquely with respect to the movement direction of the slides, causing the slides to pivot with respect to one another as soon as a specific relative movement is present between the two slides as a result, for example, of a welded contact. After pivoting, the one slide is blocked via stops which are fixed to the housing, so that the second contact in the row can no longer be closed.

Patent DE-3519265-A1 (DE)
Title: Filtration system coupled to a reactor comprising automatic sample inlet for processing and analysing samples from fermentation processes
Inventor: REUSS MATTHIAS
IPC: C12M1/26
Filed: 1985-05-25
Abstract: The filtration appliance according to the invention linked to a process control computer (Figure 1) is used for the fully automatic detection of the filtration properties of a very wide variety of biosuspensions and for coupling automatic analysers with bioreactors. The appliance comprises a filtration unit (Figure 2a) with an automatically conveyed filter belt, a photometric measuring device for detecting filtercake growth, a weighing appliance for the filtrate and the infeeds and valves for automatic charging, emptying, cleaning, sterilisation of the sample infeed, and appliances for transferring the filtrate into automatic analysers (for example HPLC). The preferred field of application of the filtration appliance is in the computer-linked monitoring and control of fermentation processes, this being an area where hitherto there has been a lack of reliable automatic processes for the important key variables such as, for example, concentration of biomass, nutrient substrates and metabolic products. The concept, on which the design of the appliance is based, that of discontinuous cake filtration in the non-sterile range, ensures the required reliability in terms of the risk of contamination for these processes. The constructional details of the appliance permit, in particular, its use for separating systems having extremely high viscosities and ensure the required purity of the filtrate for connecting automatic analysers. <IMAGE>
