Title: Process for producing a composite body containing filaments
Inventor: HILLMANN HANS DIPL PHYS DR
IPC: C22C47/06
Filed: 1985-03-02
Abstract: In the field of composite materials and in particular for wire-shaped or rod-shaped composite bodies having a multiplicity of filaments arranged in the composite body, the object exists of introducing as many filaments as possible into a billet, which is then formed by pressing or drawing to form a rod or wire. According to the invention, a mat (4) having longitudinal wires (A, B) which lie closely adjacent to one another and have a circular cross-section is woven and said mat is rolled up, if appropriate, together with a film (5, 6, 7). The rolled-up mat, if appropriate together with a tubular sleeve and a core of the rest of the material of the composite body, is then subjected to a cross-section-reducing deformation. The composite body thus formed can be used for example as an electrical conductor (superconductor), light guide (glass fibre cable) or as fibre composite material having high tensile strength. <IMAGE>

Title: DC Machine having thyristors for commutation
Inventor: NUMA KENJI
IPC: H02K29/06
Filed: 1985-03-02
Abstract: A DC machine having thyristors for commutation has an electrical armature winding having a plurality of active conductors (3 and 4) which participate in the electromechanical energy conversion of the machine. Furthermore, a commutating device having a plurality of thyristors or comparable switching elements (1) is provided, in which switching elements the change from the non-conductive state to the conductive state is carried out by means of external control signals, but the opposite change can take place only when the conductor current is zero. In this case, the switching elements or thyristors are connected to the electrical armature winding in such a manner that they control the conduction or non-conduction of the electrical current in the active conductors for commutation.

Patent DE-3525248-A1 (DE)
Title: Method for controlling and optimising reactions
Inventor: FURUMOTO HERBERT DR ING
IPC: B01J19/00
Filed: 1985-07-15
Abstract: When controlling reactions, one or more F factors F(t) are employed as a measure for the progress of the reaction. These factors can be calculated from on-line measurements of the temperature T and of one or more selected, readily accessible concentrations C. <IMAGE>   In this equation, f(T) and g(C) are functions of the temperature and the concentrations, T being the reaction time. At the end of the reactions, these factors must have reached certain values which mainly depend on the quality of the end products. This is achieved by optimising the course of the temperature and/or possibly the course of the concentration against time, which makes it possible to minimise the input of energy and raw materials. The method is particularly suitable for the process control of complex reactions in multi-component systems involving not readily measurable fluctuations in quality, concentration and reactivity of the starting materials. It can be implemented in a computer or computer module with process interfacing. <IMAGE>

At the ends of the two partial ducts (36, 38), a flap (22, 24) is in each case arranged adjustably in such a manner that, with the direction of rotation of the blower (30) being preserved, the flow direction in the flow duct (12) as well as the partial ducts (36, 38) is optionally reversible. <IMAGE>
Patent DE-3543142-A1 (DE)
Title: Combination brake system
Inventor: THENEE GUENTER
IPC: F16D55/02
Filed: 1985-12-06
Abstract: With the ever higher speeds of vehicles and machines, high levels of force are required for braking and large amounts of heat are developed, resulting in damage because the braking surfaces of the brake shoes are relatively small and the differential speed of the two opposing surfaces is very large. This necessitates a high pressure and results in the evolution of a large amount of heat and a very slow braking effect. The solution to the problem is as follows: the combination brake system is based on a combined unit comprising a brake drum and brake shoes in which the brake shoe is coupled to the rotation of the brake drum, with a slight reduction in the speed of revolution, via a gear system. This provides a uniform differential speed of revolution at all times when the fully circular brake disc is actuated and pressed against the fully circular brake-drum disc. The slight difference in the speed of revolution of the two braking surfaces gives rise to a high frictional resistance without the evolution of a large amount of heat, as though the element to be braked (car wheel or machine part) with the hitherto fixedly mounted brake shoes were revolving at only a very low speed, in the case of a motor car approximately 5 km/h. The weak pressure on the brake pedal required at this speed is sufficient in the combination brake system, even at high speeds, to achieve the desired braking effect. The brakes remain cool, contact-pressure intensifiers are rendered superfluous, wear of the brake material is reduced, a ... Original abstract incomplete. <IMAGE>
Patent DE-3543367-A1 (DE)
Title: Flat gasket, especially exhaust flange gasket
Inventor: LOENNE KLAUS DIPL ING
IPC: F01N13/18
Filed: 1985-12-07
Abstract: An optionally metallically reinforced and laminated graphite flat gasket material is provided, preferably over its entire surface, with a thin metal coating, preferably of copper or nickel, which has been deposited electrolytically or by an electroless method. The metal layer protects the oxidation-sensitive graphite against oxidation by the action of air, without significantly modifying its deformation characteristics. The material can therefore be used to give an improved seal as a high temperature gasket exposed to oxidation conditions, above all as an exhaust flange gasket. Since the metal coating additionally possesses the effect of improving adhesion to polymer layers it can advantageously also be used particularly in cylinder head gaskets made of graphite or having graphite inserts. <IMAGE>

Patent DE-3615151-A1 (DE)
Title: Mounted chopper for combine harvesters
Inventor: WIENEKE FRANZ PROF DR ING
IPC: A01F12/40
Filed: 1986-05-05
Abstract: Chopped or coarsely broken straw, when mixed in the soil or lying on the soil in a layer, requires a relatively long time for decomposition, namely biological and chemical disintegration. During this time, toxic substances escape from the straw and are highly detrimental to the germination and growth of the introduced seed. Splicing open and shortening the stalks to form spliced chaff make it possible to accelerate the decomposition of straw considerably, so that sowing can be carried out a short time after harvesting. The treatment of straw to form spliced chaff is carried out by means of fine-toothed rotating tools.

Title: Wing for ultralight aircraft
Inventor: FISCHER ALBRECHT PROF DR
IPC: B64C3/50
Filed: 1987-03-16
Abstract: This ultralight aircraft wing having a D strut has ribs which are folded around laterally in order to improve ground transportation. Instead of having a profiled shape, these ribs may consist of only two elastic rods which are spread at the front and are combined at the rear and tighten the upper and lower fabric covering at the rear end by means of rubber springs. The fabric covering is inflated behind the D strut by the air forces to produce a profiled shape, for which purpose it is designed to be airtight on the top of the wing and porous on the bottom of the wing and has blowing slots in order to delay flow separation when flying slowly. The profile thickness can be enlarged in flight by means of built-in inflatable plastic film air bags. The clamping rib rod ends which project out of the wing at the rear are used to attach flaperon-type aileron curved flaps to the wing in a simple manner. A multifunction wing is thus implemented in a simple and cheap manner.
Patent DE-3713833-A1 (DE)
Inventor: MEINEL WALTER B
IPC: H05K1/03
Filed: 1987-04-24
Abstract: A dual cavity semiconductor package (1) containing a high voltage (greater than 1500 volts) isolation amplifier includes a ceramic substrate with tungsten metalization thereon defining die bonding and wire bonding sites and interconnections in the two cavities (3,4) for input and output circuitry of the isolation amplifier, respectively. The metalization also defines a pair of precisely matched planar fringe capacitors (10,13) forming a high voltage small signal isolation barrier located between the two cavities. A layer of ceramic having apertures therein defining the two cavities is laminated over the substrate. The assembly is cofired at about 2,000 DEG Centigrade, causing ceramic to fill the gaps between the conductors of the fringe capacitors, providing very high voltage isolation therebetween. Separate tungsten sealing rings (71,72) are provided around the peripheries of the cavities on the top surface of the second layer. In another embodiment of the invention, a single large cavity has spaced separate regions for input and output circuitry of the isolation amplifier; a transformer has coils defined by printed conductors combined with wire loops. A further embodiment uses a multilayer capacitor for the isolation barrier. <IMAGE>

IPC: B65G43/02
Filed: 1987-04-29
Abstract: The belt 1 is suspended from a guiding rail 30 through a plurality of rolling supports 29. An electronic detector 7 receives the signals sent by three optical fibre cells 8, 9, 10 transversely arranged with respect to the belt and aligned with its symmetry axis, two of which 8,9 are at a distance apart corresponding to the mesh gap slightly increased by a pre-established magnitude, whereas the other one 10 is spaced further from the first one 8, thereby recording by corresponding counters 19,23,24 the total number of meshes of the belt, of worn meshes, and of meshes to be replaced, depending on whether the first cell 8 detects the mesh gaps, the outputs of the first two 8,9 simultaneously coincide at a mesh gap, or the outputs of the three of them 8,9,10 coincide at a mesh gap. When the outputs of the three cells coincide at a mesh gap, which indicates that a mesh 2 and bolts 4 must be replaced for excessive wear, a paint sprayer is actuated, so that the mesh previous to the defective one is painted, this previous mesh being located out of the field of action of the cells. <IMAGE>

Title: Extrudate regulator
Inventor: LIER GER H J VAN
IPC: B28B3/26
Filed: 1987-06-01
Abstract: To influence the flow rate of an extrudate of a ceramic composition which is fed to a die orifice (4) for producing extruded panels, a housing (12) through which the ceramic material can flow and which is in the form of an intermediate part is disposed upstream of the die orifice (4) and said housing (12) is provided with a multipart blocking element (21), the blocking elements (bolts 31) of which are arranged so as to be individually adjustable in the direction of the ceramic material. By virtue of this design, it is possible by simple means to act on an extrudate such that it is compacted virtually uniformly at all points, so that deformations of the mouldings produced from said extrudate and also ridges on the surface thereof are reliably avoided. Furthermore, the material compaction can be easily adjusted and wear at the components of the die orifice (4) can be compensated for without difficulty. <IMAGE>
