Title: Method for detecting leaks present in switching films
Inventor: BLOECHL FRANZ DIPL ING
IPC: H01H13/702
Filed: 1984-05-30
Abstract: The invention relates to a method for detecting leaks present in switching films, the individual contact points, which can be switched individually by actuating elements and are located in air chambers, being connected to one another by air ducts and tightly sealed against the outside. It is the object of the invention to indicate a method for checking switching films for leaks which permits simple and automatable detection of leaks in switching films. This object is achieved when plungers are pressed sequentially in time onto the contact points onto the switching film (1) in such a way that these plungers remain in this position, the contacts closing, when the air present between the contact points is sequentially pressed into the air chamber of the last contact point, and when a leaky switching film can be detected if contact is made in the last air chamber. <IMAGE>

Title: Process and device for preparing foamed concrete
Inventor: RIKER RUDOLF ING GRAD
IPC: B28C5/38
Filed: 1984-09-11
Abstract: Between the driver's cab (14) and the mixing drum (18) of a conventional automobile-mounted mixer (10) there is disposed a foaming system (20) having a water tank (24), a premixing tank (26), a liquid pump (36), a compressor (42) and a foaming pipe (38). During the journey to the construction site, a concrete filling in the mixing drum (18), a water supply in the water tank (22) and a small amount of foaming concentrate in the premixing tank (26) are transported separately from one another. At the construction site, the foaming concentrate is mixed with water and the mixture is pumped into the foaming pipe (38) with the simultaneous feed of compressed air and the foam thus produced is introduced through a foam discharge line (48) into the mixing drum (18) and mixed into the concrete. <IMAGE>

Patent DE-3439676-A1 (DE)
Title: Method for coding digital signals or alphabets with one, two (e.g. telegraphy binary code) or multi-stage code elements and their transmission
Inventor: DIRR JOSEF DIPL ING
IPC: H04L27/24
Filed: 1984-10-30
Abstract: In methods of this type, transmission was hitherto performed by means of alternating current pulses. Pulses of this type were switched on, off and over purely on a time, and not a phase-dependent, basis. As a result, the signals were already distorted in the transmitting station. The invention prevents such distortion by dimensioning the pulses by means of the number of periods of the respective alternating current and the respective alternating current is always switched on, off or over either at zero degrees or 180 degrees. The significant conditions which are characterised in particular by the size of the amplitudes are defined in such a way that no condition ever assumes a zero value. The alternating current is transmitted in an uninterrupted sequence of positive and negative half-waves.

Patent DE-3444247-A1 (DE)
Title: Method and apparatus for producing a wire weld-on end on winding spools
Inventor: THOR STRATEN DETLEF DIPL ING
IPC: B65H75/28
Filed: 1984-12-05
Abstract: The invention relates to a method for the production of a long extended inner weld-on end on a winding spool and to an apparatus for carrying out the method. The aim of the invention is to reduce down-times on stranding machines and to reduce residual lengths of wire. The object on which the invention is based is to produce wire weld-on ends on spools in double-spool machines with conventional catcher systems. The object is achieved according to the invention by virtue of the fact that wire is unwound from the core of the spool via windows in the spool flange following the winding process and is passed to the periphery of the spool on the inside of the spool flange, through radially arranged slots. The invention can be applied to spools with wound-on stock in strand form, e.g. for insulated wire and cable, on SZ machines and double-twist stranders.

Patent DE-3502439-A1 (DE)
Title: Handrail for a stairway
Inventor: SCHULTE KURT
IPC: E04F11/18
Filed: 1985-01-25
Abstract: Up until now, the ends of the bars of stairway handrails have had to be precisely mitred in order to correspond to the vertical progression of the adjacent wall corners and wall edges, while taking the rise of the stairway into consideration. The outlay for this is high. Doing the finishing touches on site usually produces unsightly results. In order to avoid these, the ends 10 of the bars are now enclosed by caps 11 comprising two shell elements 12 connected to each other. The shell elements 12 are fixed by screwing or clamping on the ends 10 of the bars. Expediently, the surfaces of the shell elements are adapted to the surface structure of the bars 8, 9. <IMAGE>
Patent DE-3505573-A1 (DE)
Title: Electrostatic dust collection filter
Inventor: MASUDA SENICHI
IPC: B03C3/155
Filed: 1985-02-18
Abstract: The dust collector containing an electrostatic filter has a dust collection zone (20) which is constructed using a small-plate filter element which has a small ply width and a short gap between the adjacent rib sections. As a number of insulating spacers with suitable interspaces are inserted in the filter element from its upstream and downstream sides, the proportion of the contact area of the spacers with respect to the filter element is small, and the proportion of the dust collection zone is high. Electrodes are provided at the upstream and downstream rib sections of the filter element, and a high voltage is applied between these electrodes, so that a uniform and stable electric field is applied to the entire filter element. This makes it possible to achieve a high dust-collection efficiency. <IMAGE>

Occasions when the limiting values are exceeded and which are detrimental to quality are signalled on an output device (AG). Control circuits and methods for various welding methods, and a light-sensor device (L), are disclosed. <IMAGE>

Title: Method for S-neutrino telecommunication
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: H04B13/00
Filed: 1985-09-10
Abstract: The S-transformation is used for definition of neutrino generation and processing and, according to their definition at the Gaussian level of complex numbers, neutrinos are neutral graviton-type quanta with zero rest mass and they result from the slowing-down of neutrons. In order to identify and differentiate between them, thanks to their high energy, in neutrino telephony and telegraphy as carriers of modulated or digitised information in a gas, liquid or solid substance detector directed in the receiver at the incoming neutron stream, optical or X-ray light can be sent for example through a crystal body serving as a detector, the optical or electronic effects can be measured at the light exit with a measuring device and the resulting data can be transformed, e.g. translated into sound, text or speech. This may involve, for example, light motion changes in a crystal detector or electric conductivity changes in a semiconductor substance. However, other gravitational effects may be effective for detection and deciphering.

Title: Process and apparatus for decreasing nitrogen oxides in exhaust gases
Inventor: BARIN IHSAN PROF DR
IPC: B01D53/56
Filed: 1986-03-22
Abstract: The invention relates to a process and an apparatus required for carrying out the process for decreasing nitrogen oxides in exhaust gases of any type by plasma impingement. In a known process, the exhaust gas is passed through a plasma which is built up between two or more electrode plates which are arranged at a spacing of a few millimetres, parallel to each other and mutually surface-covering. However, such an apparatus is only suitable for reducing nitrogen oxides in small amounts of exhaust gases, but not for the hot and dust-laden exhaust gas arising in large amounts from industrial furnaces. Decreasing NOx in large amounts of exhaust gas is achieved according to the invention with a plasma gas burner producing a plasma gas jet to which defined media are fed which are present in the plasma gas jet as reducing gas species such as excited H2<*> molecules, H<*> atoms or other free radicals and are brought into contact with the pollutant-containing exhaust gas at temperatures of 500 to 950 DEG C and reduce the nitrogen oxides to molecular nitrogen.
