Title: Conduit for flexible hoses or cable - has parts of interlocking strip turn edges bent to prevent movement in one direction
Inventor: KLEIN ERNST
IPC: B21C37/12
Filed: 1979-03-28
Abstract: The conduit bends in one direction, being for the guidance of flexible hoses or cables between a stationary union and a moving machine. It comprises a spiral profiled strip with edges bent towards each other and fitting over those of adjacent turns. The turns are prevented from moving in the lengthwise direction in an area of the periphery parallel to the conduit axis, and for the remainder can do so for a limited amount. In the first area the edges of the strip turns are so bent towards the central portion that the edges of the adjacent turns are clamped in the folds formed and cannot move.

Title: Dewatering of sewage sludge - by freeze-thaw treatment before adding flocculant
Inventor: SPEI BRIGITTE
IPC: C02F11/20
Filed: 1979-04-05
Abstract: Dewatering of domestic sewage sludge by addn. of treating (esp. flocculating) agents followed by mechanical or dynamic dewatering is improved by cooling the sludge to >0 degree C (pref. -3 to -50 degrees C, esp. -5 to -20 degrees C) and then warming to >0 degree C before adding the treating agent. The freeze-thaw treatment greatly increases the solid content of the dewatered sludge. Prefd. flocculating agents are acylamide homo- and copolymers, esp. those contg. tert. amino or quat. ammonium gps. The flocculating agents are pref. added in an amt. of 50-200 g/m3. Primary sludge with a solids content of 6.2% was treated with 200 ppm of a polyacrylamide flocculant modified with 50% 2-methacryloylethyl-trimethylammonium chloride and then suction-filtered for 5 min. The prod. had a solids content of 26.6%. The same sludge was cooled to -5 degrees C, warmed to room temp. after 5 min., treated with 80 ppm of the same flocculant, and filtered. The prod. had a solids content of 38.4%.

Title: Industrial furnace for carburising metals - where excess carburising gas is burnt in flare fitted with electric igniter to eliminate gas consumption by pilot flame
Inventor: KLIW JUERGEN
IPC: C21D1/74
Filed: 1980-03-29
Abstract: Industrial furnace for carburising metals. The furnace is esp. of the pusher type, and has a treatment chamber fed with a carburising gas, the excess gas being burnt in a flare located at the inlet and/or outlet of the furnace.

The igniter pref. consists of a pair of electrodes creating a spark directly above the flare outlet and in the path of the carburising gas. Alternatively, when there is no flame at the flare outlet, another gas may be released and ignited, and used to ignite the excess carburising gas. The use of a pilot flame obtd. e.g. from town gas, and using an appreciable amt. of the latter, is eliminated.

Title: Roller shutter advance intrusion alarm system - has two contacts activated simultaneously by forcible raising, and wire releasing alarm if torn
Inventor: TREUSCH GEORG
IPC: E06B9/86
Filed: 1980-04-02
Abstract: Initial warning of forced entry into a door or window is provided by a system operating in conjunction with roller shutters on windows and doors. Two fixed electrical contacts, connected to an alarm device, are mounted so that when the shutter is forced upwards they are both activated at the same time, but correct winding up results in activation one after the other. An alarm wire is stretched, in relation to the shutter, so that the eye-loop embraces the wire in every opening setting. It is linked to the alarm device with an operative tension, so that this is set off if the wire is torn. The two processes may be used separately and independently.

Title: Colour display with phosphor coated gas discharge cells - has colour filter series connected in front of same colour image points
Inventor: MARZEL OTTO DIPL CHEM
IPC: H01J17/49
Filed: 1980-05-02
Abstract: The image points in a flat display screen are formed by numerous gas discharge cells coated with phosphor. Each displays a different colour in dependence on the type of phosphor used. A filter is incorporated in front of the image points, at least of the same colour, which is transparent for the emitted light by the respective phosphor. Preferably such filters are transparent only in the emission region of the image points in front of which they are fitted. Image points of several colours may have common filters. A purple filter may be used for red and blue image points, a cyan filter for blue and green, and a yellow filter for green and red. Filters for image points of a single colour may be combined with filters for multi-colour image points. The filters may be fitted on the front or rear side of the display screen.

Title: Induction motor with two independent stator windings - has windings supplied from fixed and variable frequency sources for speed control
Inventor: WILMERS GOTTLIEB DR ING
IPC: H02P27/048
Filed: 1980-05-30
Abstract: The cage type induction motor is built with two independent three phase stator windings (9,10). One winding is supplied at mains frequency, the other is connected to a variable frequency supply. By constructing the machine in this manner, the power output of the necessary frequency converter can be reduced and consequently the overall efficiency increased. The motor speed is determined by the sum of the frequencies, and the number of poles. The stator windings may be in adjacent cores or be made with one winding over the other. If the variable frequency winding is connected for the opposite rotation to that of the fixed frequency one speed control down to standstill can be achieved. Start up is normally on fixed frequency.

Title: Offset printing forme and method of producing it
Inventor: OVCINNIKOV JURIJ MARKOVIC
IPC: B41N3/08
Filed: 1981-01-12
Abstract: The offset printing forme according to the invention is a carbon-steel plate on whose surface printing and non-printing elements are arranged. The printing elements are made of the material of a copying layer based on o-naphthoquinone diazidesulphonic or -carboxylic acid derivatives or of the material of a copying layer which is a photopolymerisable composition. The said printing elements form a relief over the surface of the plate. The non-printing elements are made of the hydrophilised metal of the plate, the hydrophilised carbon steel. The method of making an offset printing forme is to apply a copying layer based on o-naphthoquinone diazidesulphonic or -carboxylic acid derivatives or a copying layer which is a photopolymerisable composition to the carbon-steel plate. After the said copying layer has been dried, the image of a transparency is copied onto it, the transparency being a diapositive if a copying layer based on o-naphthoquinone diazidesulphonic or -carboxylic acid derivatives is used, or a negative if a copying layer is used which is a photopolymerisable composition. The image is developed by removing the regions of the copying layer from the non-printing elements using a 0.2 to 1.5% strength aqueous solution of alkali-metal salts or alkali hydroxides at a temperature of 18 to 25 DEG C. The non-printing elements are hydrophilised using an aqueous solution containing 5 to 10% of a salt formed by an alkali metal and an inorganic cyanide complex and 0.5 to 2% of an organic hydrophilic colloid at a temperature of 20 to 25 DEG C. The invention can be used in the graphics industry.
