Title: Needle for tufting machines
Inventor: FUHRMANN WOLF-DIETER
IPC: D05C15/20
Filed: 1985-12-21
Abstract: The invention relates to a needle for tufting machines, with a needle butt serving for clamping or shaping and with an adjoining shank which terminates in a needle tip and which is designed, for the guidance of the respective thread, with a needle eye and a guide groove extending from the needle eye in the direction of the needle butt and, on the side located opposite the thread-guide groove, with a run-on face, in the region of which the needle, after being inserted into the basic material, cooperates by non-positive bearing contact with a gripper forming a thread loop. In order to prevent wear of the needle tip by the gripper, the positions of the needle tip and of the bearing face of the run-on face for the gripper are offset relative to one another transversely to the longitudinal axis of the needle, in such a way that, during a retracting of the needle, the needle tip maintains a safety distance relative to the gripper.

Patent DE-3608100-A1 (DE)
Title: Cut-off valve
Inventor: ALTMANN HANS-PETER DIPL ING
IPC: F15B1/027
Filed: 1986-03-12
Abstract: The invention relates to a cut-off valve which, in particular in hydraulic accumulator circuits, switches the pressure medium to pressureless circulation when a top switching pressure is reached and switches it again to a bottom switching pressure during a pressure drop. The switching is effected as a function of pressure via a main control piston with two effective areas. One of the effective areas is permanently acted upon by the pressure of the circuit. The other effective area is acted upon by a pressure which is monitored by two pilot-control valves, of which one switches on or switches off the circuit at the bottom switching pressure and the other limits the pressure at this effective area in accordance with the top switching pressure. To improve the switching behaviour, a connection with a restrictor and a non-return valve is fitted between the feed and the effective area, which connection is closed at least when the main control piston has switched to pressureless circulation.

Title: Partition
Inventor: WEITNER HEINZ-UWE
IPC: E06B5/16
Filed: 1986-04-10
Abstract: In order to prevent the fire from spreading there are installed, in ceilings and walls, particularly around cable shafts and other lines, hard partitions which are intended not only to be fire-resistant, but, furthermore, often also to be water-tight and secure with respect to earthquakes. In order also to be able to fit out old buildings therewith, said partitions should also be capable of being retrofitted. These requirements may be fulfilled in that the provided opening in the ceiling or wall is surrounded by a metal frame and the partition panel, inserted into said opening, is likewise enclosed by a somewhat smaller metal frame which can be strutted in its interior in order to increase the stability of the panel. The two metal frames are connected to one another by strong helical springs, with the result that, in spite of sufficient pressure stability, the arrangement is flexible enough in order to withstand relatively large vibrations. For the capacity of the arrangement to be retrofitted, the partition panel has to be configured in a number of parts, for lines which run through continuously. The joint between the two metal frames, in which the helical springs are located, is filled, after mounting, by fire-resistant materials in order to eliminate the joint.
Patent DE-3612684-A1 (DE)
Inventor: HEUSSER MARTIN DIPL ING
IPC: F15B11/04
Filed: 1986-04-15
Abstract: The invention relates to a hydraulic control apparatus comprising a hydraulically adjustable throttle opening between an inlet passage and an outlet passage, a three-way pilot valve connected to an external actuator and having its inlet connected to a control pressure inlet passage, its control outlet being connected to the throttle valve in such a manner that the throttle valve element thereof is adapted to be biased in opposition to the pressure in the outlet passage and to the force of a spring. Known control apparatus require the employ of a displacement sensor for sensing the position or displacement of the throttle valve element and for correspondingly acting on the actuator to thereby vary the actuating force thereof for maintaining the opening degree of the throttle opening. This construction involves considerable complications. It is also disadvantageous that the pilot valve is subjected to the full operating pressure, requiring it to be of a highly accurate and therefor expensive construction. According to the invention the second outlet of the three-way pilot valve is connected to the outlet passage, and the valve element of the pilot valve is subjected to the pressure at the control outlet in opposition to the actuating force and to the pressure at the second outlet, and the inlet pressure supplied to the pilot valve is higher than the outlet pressure at least by the maximum possible pressure difference over the pilot valve.

Title: Platform balance or bridge balance consisting of individual platforms
Inventor: GIESECKE PETER DR
IPC: G01G3/12
Filed: 1986-05-09
Abstract: A platform balance or bridge balance consisting of at least two individual platforms which are supported via force-measuring cells on the ground or on a foundation is to allow a perfect three-point support of the individual platforms even when the erection or foundation surface is not plane. This is achieved in that individual platforms (1-4, I, II, 22, 25) are of triangular design, and in that they are supported on the force-measuring cells (5-10, 22) at the corners directly or indirectly via one or more adjacent platforms, at least one individual platform being supported indirectly at at least one corner. As a result of the design and support according to the invention of the individual platforms, a statically determined support of each individual platform is obtained, whilst the entire balance can be adapted without constraint to ground unevenness. Weighbridges of any size can be formed by means of the individual platforms. <IMAGE>

Title: ECL step circuit
Inventor: PERY ANTOINE
IPC: H03K19/086
Filed: 1986-07-22
Abstract: In an ECL step circuit of n series-connected stages, the supply voltages U1, U2,...,Un for the individual stages S1, S2,...,Sn are increased from stage to stage by the base-emitter voltage UBE of the transistors provided. This is achieved by the (n-m)th stage being supplied with a central supply voltage Uc via m series-connected diodes, m assuming the values from 0 to (n-1). As diodes, transistors are provided in which the base is connected to the collector. Due to this measure, the emitter followers for voltage matching between the individual stages can be omitted. Instead of 2(n-1) emitter followers with 2(n-1) transistors and 2(n-1) emitter resistors, an n-stage ECL step circuit according to the invention only requires n-1 transistors. <IMAGE>

Title: Process for the precipitation and removal of cadmium from the raffinates of phosphoric acid purification
Inventor: BELTZ KLAUS DR RER NAT
IPC: C01B25/46
Filed: 1986-10-25
Abstract: The present application is an addition to the main application P 3622597.5 and is a variant of the process for precipitation and removal of cadmium sulphide from the raffinates of phosphoric acid purification with the aid of polysulphanes, by treating the cadmium-containing raffinate streams with a solvent phase in the presence of polysulphanes in a mixer-settler apparatus, separating off the raffinate phase from the solvent phase containing cadmium sulphide and isolating the precipitated cadmium sulphide from the solvent phase. With the aid of the process, the raffinates can be freed of cadmium in a simple way, since their inherent properties have no influence on the precipitation and removal of the cadmium sulphide.

Title: Method and device for achieving a safe landing for fixed-wing aircraft which are not equipped with VTOL devices or whose present flying characteristics are limited, and for externally assisted takeoff, without any takeoff run, for fixed-wing aircraft
Inventor: SCHROEDER BAERBEL
IPC: B64D3/00
Filed: 1986-12-23
Abstract: The invention relates to a method and the devices which are required to carry it out in order to achieve safe vertical landing of fixed-wing aircraft which are not equipped with VTOL devices or whose present flying characteristics are limited, and to externally assisted takeoff, without any takeoff run, of fixed-wing aircraft. A fixed-wing aircraft which is provided with lower retaining means is coupled in flight to the rotary-wing aircraft with the aid of upper retaining means, which are supported by a rotary-wing aircraft above the fixed-wing aircraft. The rotary-wing aircraft produces the forward thrust and lift force required for transportation of the fixed-wing aircraft and lowers it vertically. Takeoff without a takeoff run is initiated by the rotary-wing aircraft lifting the fixed-wing aircraft and accelerating it in its direction of flight. When the altitude, airspeed and the fixed-wing aircraft's own thrust are sufficient, said fixed-wing aircraft releases the connection to the upper retaining means of the rotary-wing aircraft and flies autonomously. <IMAGE>

Title: Circuit arrangement for decoupling the output of a voltage converter
Inventor: GOETZ RAINER DIPL ING
IPC: H02M3/155
Filed: 1987-02-19
Abstract: A circuit arrangement is specified for decoupling the output of a voltage converter which supplies a DC network. The voltage converter contains a controllable switch (V1) in addition to a decoupling diode (ID) on the output side. This controllable switch (V1) bridges said decoupling diode as soon as the filter capacitor (C1) of the voltage converter is at the converter required voltage. A MOSFET, for example, is used as the controllable switch, which is driven by a sensor circuit via an optocoupler (OK1a, OK1b). The bridging of the decoupling diode, which may also be the inverse diode (ID) of the MOSFET, results in the diode forward-flow losses being reduced, and the influence of the non-linearity of the diode on the value of the converter output voltage (UA) is overcome. <IMAGE>

Title: Method for determing the direction of a frequency shift of a high-frequency radiation
Inventor: BISELLI EUGEN DIPL PHYS
IPC: G01S17/95
Filed: 1987-04-18
Abstract: In a method for determining the sign of a frequency shift of a high-frequency radiation, the frequency of this radiation, for example a laser radiation, is doppler-shifted on a moving object and some of the doppler-shifted radiation power is then fed back in a resonator, when laser radiation is used in a laser resonator, and amplified in the latter. The gain obtained is then measured by means of a receiver in dependence on the frequency of the high-frequency radiation. The gain is given by the gaussian or lorentz characteristic of the line in dependence on the frequency. Using this method for determining wind directions, different gains can be achieved for different wind directions from which different signals can then be generated, by means of which the wind direction can be determined.

Title: Methods for the genetic engineering production of antigens and their use in an approach to confirmatory tests for antibodies in the example of human immunodeficiency virus (HIV)
Inventor: SOUTSCHEK-BAUER ERWIN DR
IPC: C07K14/16
Filed: 1987-07-21
Abstract: This invention entails the detection of HIV 1 antibodies in human serum samples or CSF in a reliable and more sensitive manner than has been possible with Western blots using virus preparations as antigen. This invention also describes the generation of recombinant DNA molecules which carry HIV 1-encoding protein segments and which ensure stable expression of these protein segments in E.coli. This stable expression in E.coli takes place without heterologous fusion proteins in order to be able to rule out non-specificities against E.coli constituents in a test. Furthermore, this invention permits, by use of the recombinant antigens in a particular test approach, a more sensitive detection of HIV 1 antibodies and, at the same time, a reliable differentiation from non-specific reactions. Finally, the approach described in the invention is orders of magnitude more favourable in cost terms than the previously used HIV 1 confirmatory test (Western blots with viral purified antigens).
