Title: Immunoassay reagent and immunoassay method
Inventor: NOMURA YASUSHI
IPC: G01N33/532
Filed: 1986-01-31
Abstract: Microcapsules in which a chelating agent is incorporated are labelled either with an antigen or with an antibody. These microcapsules are introduced together with a metal salt, a supplement and a sample containing an antibody to be determined or an antigen to be determined into a reaction vessel. The immunological reaction induced thereby releases the chelating agent from the microcapsules, and it binds the metal ion with formation of a colour. The coloured reaction solution is then determined by photometry and the concentration of the antibody or antigen to be determined is found from the extinction at a particular wavelength. The invention makes an immunoassay method possible with extremely small measurement errors.

Title: Method and device for SZ stranding (twisting) of cable cores with a sector-shaped conductor cross-section
Inventor: VOGELSBERG DIETER DIPL ING
IPC: H01B13/02
Filed: 1986-03-04
Abstract: In order to be able to SZ strand in any direction of lay cable cores having a sector-shaped conductor cross-section, with more than two stranding lays, and in this case to keep the manufacturing cost as low as possible, a stranding disc, which is driven with an alternating rotation direction, is provided as the stranding device. In front of this stranding disc, the cable cores are guided helically with respect to the stranding axis over a length which is at least equal to the distance between two reversal points of the direction of lay in the completed stranded material. When it passes through the stranding nipple which is connected downstream of the stranding disc, the stranded assembly is held together by suitable dimensioning of the cylindrical part of the stranding nipple such that skewing of individual cable cores is prevented. The new stranding technique can be used especially in the production of three-core or four-core 1kV cables. <IMAGE>

Title: Turbulence-creating body for heating-gas flues and a method for its production
Inventor: WECKS EGON
IPC: B21D53/02
Filed: 1986-05-23
Abstract: A turbulence-creating body (1) for heating-gas flues, especially those of fuel-heated hot-water tanks, consists of a sheet-metal strip (2) which is coiled and has transverse fold lines (5). Each fold line is formed by bending the strip, the bends of successive fold lines (5) respectively pointing in opposite directions. The successive fold lines (5) are each formed so as to rise in opposite directions from the horizontal. The twisting of the turbulence-creating body (1) is produced solely by means of the bends without the necessity for an additional deformation process. The angle between successive fold lines (5) also influences the steepness of the twist, making it a simple matter to produce a turbulence-creating body (1) with a pitch which varies over its length. <IMAGE>

Patent DE-3621915-A1 (DE)
Inventor: BENNING FRIEDRICH DIPL ING
IPC: B62D25/12
Filed: 1986-06-30
Abstract: A suspension mechanism is provided for a hinged part, such as the engine hood of an agricultural tractor. The top of the engine hood is pivoted on an axle via a forked bearing. A follower on the bottom of the engine hood is guided in a track on the vehicle tractor frame. A support strut is provided at the front end of the hood. So long as the support strut is attached, the hood can pivot about the axle and the follower will move in the guide track on the frame, but the hood cannot be removed because the follower cannot leave the track. To remove the engine hood, the support strut is detached from the hood. The follower then can pivot entirely free of the track and the hood can simply be lifted off of the axle support. The support strut preferably is an outwardly biased pre-loaded gas pressurized spring reaching its shortest length somewhere between the open and closed positions of the hood. The spring then will bias the hood towards its open and closed positions.

Title: Process for treating contaminated silt and plant for carrying out this process
Inventor: KUPCZIK GUENTER DIPL ING
IPC: C02F1/52
Filed: 1986-09-26
Abstract: For the treatment of contaminated silt, even in the form of mud-type materials, in particular with contamination by heavy metals, iron ore particles are added to a silt suspension prepared by addition of water. The result is a precipitation of impurities, with discharge of the parts loaded with pollutants. This discharged mixture, enriched with iron ore particles, is fed to a metallurgical process in the blast furnace, in which the ores are recovered and the pollutants are at least neutralised by the heat generated. In particular, the silt mass with the pollutants bonded to the iron ore particles is passed through a magnetic field in which the magnetisable iron ore particles with the pollutants are separated off.

Patent DE-3701011-A1 (DE)
Title: Device for shutting off supply lines, particularly gas pipes
IPC: F16L55/124
Filed: 1987-01-15
Abstract: In the case of known shut-off devices, a tubular branch is seated essentially at right angles on the supply line, the inside diameter of the tubular branch corresponding to the inside diameter of the supply line. The tubular branch accommodates a valve insert, the valve insert having a cylindrical sealing plug which is provided with a hemispherical tip, is composed of soft-elastic material such as rubber, plastic etc., can be displaced in the longitudinal direction of the tubular branch through an opening in the wall of the supply line into the supply line and, in the shut-off position, is compressed in frictional engagement with the inner wall of the supply line and of the adjoining part of the inner wall of the tubular branch. The sealing plug is vulcanised to a valve plate which can be adjusted by means of an external thread in an internal thread of the tubular branch. During use of the valve plug as intended, it has to be turned in the tubular branch and this gives rise to wear due to the friction against the inner wall of the tubular branch. In addition, the sealing plug, composed of soft-elastic material, may be subject to cold flow in the compressed position so that its outside diameter is oversized relative to the inside diameter of the tubular branch, thereby making operation more difficult or impossible. In order to achieve ease of operation during use as intended, ... Original abstract incomplete.
