Patent WO-9418025-A1 (WO)
Inventor: CHEN LEI
IPC: B60L15/20
Filed: 1994-02-05
Abstract: Véhicule électrique à rendement élevé permettant des économies d'énergie et comportant un jeu de batteries rechargeables (7) à titre de source d'énergie, et un certain nombre de moteurs électriques d'entraînement (1, 2) à niveaux de puissance différents. Chaque moteur (1 ou 2) possède son propre système de circuits électriques et appareillage de connexion. Lors du démarrage du véhicule, ou lorsqu'il roule sur une route en pente montante, ledit véhicule est soumis à une résistance accrue et à la fois le moteur (1) à niveau de puissance élevé et le moteur (2) à niveau de puissance moins élevé sont actionnés simultanément afin de produire une force correspondante. Lorsque la force d'inertie du véhicule augmente et que la résistance diminue à la suite du démarrage, seul le moteur (2) à niveau de puissance moins élevé est actionné, ce moteur (2) imprimant plus de révolutions à un essieu moteur que le moteur (1) à niveau de puissance élevé. Ainsi, la consommation d'énergie est réduite et l'autonomie du véhicule après chaque charge est prolongée.
Patent WO-9504849-A1 (WO)
Inventor: SRAITR STANISLAV
IPC: D01H4/08
Filed: 1994-08-03
Abstract: The object of the invention is a method of yarn (10) production in a spinning rotor (1) in which the singled out fibres (4) fed into the spinning rotor (1) are collected on its collecting surface (5) into a fibre band (6) which is continuously delivered (drawn off) into the direction of the spinning rotor (1) axis and transformed into yarn (10) by twisting. The transformation of the fibre band (6) into yarn takes place in presence of axial tension separately from the creation of the fibre band (6) on the collecting surface (5). The by the twist not reinforced section (61) of the fibre band (6) which is produced between the collecting surface (5) and the beginning of the fibre band (6) transformation into yarn is shorter than the average staple length of the singled out fibres being spun. The invention also relates to a device for carrying out the method.

Title: Verfahren zur labormedizinischen liquor cerebrospinalis diagnostik einer intrathekalen immunglobulin synthese durch messung der freien kappa immunglobulin leichtketten
Inventor: ARNETH BORROS
IPC: G01N33/564
Filed: 2003-08-04
Abstract: Die qualitative oder quantitative Bestimmung der freien kappa Immunglobulin Leichtketten ist ein sensitiver Parameter zur Diagnose einer intrathekalen, d.h. einer im Liquorraum lokalisierten Immunglobulin Synthese. Beim Gesunden ist die Konzentration an freien kappa Immunglobulin Leichtketten sehr gering oder nicht nachweisbar. Bei einem Patienten mit intrathekaler Immunglobulin Produktion ist ein erhöhter Messwert an kappa Immunglobulin Leichtketten nachweisbar. Krankheiten, die mit einer intrathekalen Immunglobulin Synthese einhergehen und daher so diagnostizierbar werden sind : die Multiple Sklerose (MS), die virale Meningitis wie auch die bakterielle Meningitis (z.B. Neuroborreliose, Neurosyphilis, Kryptokokken). Die Bestimmung der freien kappa Immunglobulin Leichtketten ist ein schneller, zuverlässiger Test. Im Vergleich zur bislang gängigen Methode der Bestimmung der oligoklonalen Banden aus Liquor und Serum ist die Bestimmung der freien kappa Immunglobulin Leichtketten deutlich schneller und kosteneffizienter durchführbar. Die Messung dauert wenige Minuten im Vergleich zu mehreren Stunden im Falle der oligoklonalen Banden. Dieser Aspekt erlaubt auch eine Messung in Notfällen zur Schnelldiagnostik.

Title: Rotary tubular kiln support and drive ring fixing method
IPC: F16C13/04
Filed: 1970-03-10
Abstract: The support and running ring fixed over the circumference of rotary tubular kilns of similar barrel type equipment is fastened to the outside of the barrel by a gear tooth type locking method for the ring to the barrel circumference. The teeth locking the ring, which are arranged at regular intervals on the circumference of the barrel, and which engage grooves on the inner circumference of the ring to be fitted, consist of two wedges each of corresponding size and shape, which are inserted from opposite sides into the grooves provided. Pref. special plates with the grooves are welded to the barrel surface, the ring being supported by spacer plates in the areas between the groove plates. This method ensures that the ring is uniformly tensioned whilst at the same time permitting its easy changeover.

Title: Adhesive - coated metallised films - for application to glass to reduce radiation,using alcohol-activated adhesives
IPC: B32B17/10
Filed: 1970-06-12
Abstract: Transparent films, consisting of a plastics film, a vapour-deposited metallic coating, a protective lacquer for the metal and an adhesive for sticking to glass, in which the adhesive layer consists of polymers which can be activated by aliphatic alcohols. The adhesive layer pref. consists of a copolymer of acrylic and methacrylic esters, which can be activated with a mixture of alcohol and water, but is insoluble in water alone. The protective lacquer pref. contains a corrosion preventative for the metal. The composite films are applied to glass, esp. window panes to reduce transmission of radiation, esp. heat. Use of alcohol-activated adhesives in place of usual water-activated types prevents water-absorption in use by the adhesive and resultant discolouration.

Title: Three-electrode welder supply circuit - from three phase supply using three separate single phase transformers one or more being centre tapped
Inventor: RAPPEN ALBERT DIPL ING
IPC: B23K9/10
Filed: 1972-09-14
Abstract: By the use of the so called Scott connection, and variants of it with >1 of three separate single phase transformers centre tapped on the primary side and with their secondaries in star with the workpiece connected to the star point, the phase relationships between the currents to the three welding electrodes can be adjusted so that the maximum phase difference between the currents in the two outer electrodes is 90 degrees and that between the centre electrode and one or other of the outer electrodes is 60 degrees. In typical cases, the current in the centre is 45 degrees phase shifted from those in both outers, the phase difference between these two being 90 degrees, or with that outer bracket still 90 degrees, the centre current is phase shifted 60 degrees from one outer and 30 degrees from the other, or the total bracket may be 60 degrees with the centre 30 degres out of phase with both outers. Simple method for obtaining improved quality welds from three electrode welders used for higher power, but with freedom from edge burn-in and irregularities.

Title: Dehydrating sewage sludge by admixing cellulosic wastes - to create optimal conditions for biological decomposition and prodn. of compost
Inventor: HACHENEY WILFRIED DIPL ING
IPC: C02F11/12
Filed: 1972-10-16
Abstract: Sludge from municipal sewage clarification tanks is mixed with waste paper, cardboard, cellulosic textiles, or sawdust and other wood wastes to effect dehydration and ensure the optimum carbon, nitrogen ratio and moisture content for biological decomposition and formation of compost. Alternatively, the dehydrated produce can be burnt. Waste paper or cardboard exerts strong dehydrating effect due to capillary forces. Cellulosic textile materials greatly facilitate filtration. Acids, such as H2SO4 are not used so that the product is harmless and can be used as compost.
