Title: Coolant coils located in wall of metallurgical melting furnace - and fed with high velocity mist of gas and water
Inventor: COLLIN PER HARALD
IPC: C21B7/10
Filed: 1976-06-11
Abstract: Zones forming part of the walls of metallurgical furnaces and subjected to severe working conditions are cooled via coolant coils built into the wall; and a gas mixed with fine drops of water is fed at high velocity through the coils. The gas is pref. inert w.r.t. the coolant coils, and contains 10-50 wt. % of pure, de-ionised water. Both the gas and the water are pref. recirculated, and the gas pref. travels at 10-100 m/s. The total pressure in the coils is pref. lower than the pressure in the furnace chamber. The pref. plant includes a pump feeding the gas through injectors fed with water; and the mist leaving the furnace is fed through a cooler and a water separator from which the water is recirculated to the injectors. Used e.g. in a furnace wall exposed to molten slag which would normally cause rapid wear of the refractory furnace wall.

Title: Lathe for generating spherical or aspherical surfaces on workpieces - has cam mechanism and floater for advance or retract movement relative to pivot
Inventor: HOOKER DERRELL C
IPC: B23Q35/10
Filed: 1976-06-16
Abstract: A machine for generating a surface on a workpiece comprising a spindle support unit, a tool-supporting unit for supporting a tool in cooperation with the face of the workpiece. One of the members swings about a pivot located along the spindle axis to make the tool member swing across the face of the workpiece to generate the desired surface. The support carries floating means for movement relative to the pivot so that the member carried thereby is advanced or retracted relative to the pivot; yieldable biassing means acting on the floating means to cause the member carried thereby to movably advance relative to the pivot into contact with the other member, and a cam arrangement for controlling the floating movement in cooperation with the biasing means. The cam arrangement includes a cam member and a cam follower supported in normally fixed position relative to the floating means and the other being carried by the floating means. The normally-fixed member adjustable relative to the pivot axis in a direction longitudinally relative to the spindle axis.

Title: Liquid cooled roller for hot rolling mills - has coolant pipes which enter the ends of the roller and cool the whole roller area
Inventor: FRANCENJUK IVAN V
IPC: B21B27/08
Filed: 1976-06-30
Abstract: The roller is in the form of a hollow cylinder, inside which two sets of two discs are mounted. The discs support shafts which protrude from the cylinder ends and which in turn are supported on ball bearings. Ring shaped covers are mounted at the ends of the hollow cylinder which are shaped so that there is an annular gap between the inside diameter of the cover and the support shafts. Coolant inlet and outlet pipes are mounted so that they enter the cylinder through the annular gaps between the covers and the shafts. Holes round the circumference of the support discs make it possible for the coolant to flow right through the cylinder and cool the whole surface of the cylinder, thereby increasing the life of the roller.

Title: Colour density measurement of chromatograms - using opto-electric conversion and line-by-line resolution of video signal (HU 28.12.76)
Inventor: KERENYI GYULA
IPC: G01N21/86
Filed: 1976-07-23
Abstract: The colour density of an image is measured by first converting the image into an electrical video signal. This is then resolved line-by-line; each line sampled and its signal level compared with standards. By digital conversion the signal level at each point (which is proportional to, the colour density) is counted up, displayed and printed. Used for the quantitative analysis of chromatograms, elphograms, autoradiogrames, photographic reproductions or copies. The analysis method is much more rapidly than the time-consuming use of densitometers.

Title: Treating waste water, esp. from cess pits, with flocculants - then gravity filtration through textile to reduce solids and BOD
Inventor: DISSELBECK DIETER DIPL ING
IPC: C02F11/12
Filed: 1976-08-28
Abstract: A proces for purifying waste water with reduction in COD and BOD values which requires a preliminary sepn. before a further purification comprises the following. Flocculating agents are added to the waste water and the greater part of the colloidal constituents are eliminated by passing the water through a gravity filter comprising a support material in an appts. contg. it to form a filter consisting of the support material and a layer of sepd. solids, which removes the colloidal constituents. The appts. forms the first part of water-treatment stations which also includes a further purification means comprising either a biological or a physico-chemical treatment followed by means for the sepn. of the resultant sludge. The process is partic. used to treat effluent from cess-pits and sludges collectors. The process has the advantage of reducing the COD (up to 20,000 mg/l.) in a preliminary sepn. stage. It is also cheaper and more adaptable than current first sepn. methods which require expensive concrete tanks with long sepn. times.

Title: Directional valve for control of working cylinder - has actuating pistons of smaller dia. than each of two valves
Inventor: CORDES HUGO DIPL ING
IPC: F15B13/04
Filed: 1976-11-30
Abstract: The valve controls the fluid supply and return of a working cylinder. Each cylinder space has two valves, hydraulically actuated by pistons. The actuating pistons have a smaller dia. than the valves. During reversal, the open path/seat valve is closed by pressure changes at the actuating piston, and the closed valve is opened only after the pressure in the working cylinder chamber is at the same level as that in the supply/return. The two pressures are brought to the same level by the movement energy of a mass, which is connected to the working cylinder and which continuously moves during reversal. The main lever has a start-up position, in which only an actuating fluid supply is possible. In an active position, the working fluid is supplied, after the switching of the valves.

Inventor: SCHMIDT OTTO
IPC: C23C18/16
Filed: 1976-12-22
Abstract: Individual fibres in a bundle are coated by exposing the bundle to a reactive soln. for electroless chemical plating of a substance onto the fibres. At least a part of the loose fibre bundle is suspended vertically while the soln. travels downwards along the fibres. The bundle may be suspended from one end or from both ends to form a U-shaped loop; and the soln. pref. travels at a speed with prescribed min. and max. The coating is pref. a metal, esp. Cu, Ni, Co or Sn; and the suspended bundle may be treated with other liqs, both before and after coating. The soln. may be poured or sprayed onto the bundle and then recirculated; and a continuous process can be used. After coating with metal, a second, more noble metal can be applied by electroplating using 2-500, esp. 10-100 mA/cm2 of fibre surface.

Title: Shock-absorber and noise-insulator laminated with plastics foam - which assumes honeycomb structure by regular incisions being pulled apart
Inventor: ALFTER FRANZ-WERNER
IPC: E04F15/22
Filed: 1976-12-30
Abstract: Shock-absorbing and/or noise-insulating panels or webs have a layer of plastics foam with "chambers" to give it a honeycomb-like configuration, similar to that of so-called "expanded metals". This configuration is obtd. by providing the foam layer with incisions passing through its entire thickness. These incisions lie across the machine direction of the panels or webs and are "opened out" by pulling the foam layer along the machine direction. To maintain the shape of the so-formed "honeycomb" cells the foam layer is laminated on 1 or both sides. Used in construction of resilient and noise-absorbing floors and/or walls e.g. in sports halls, hospitals.

Title: Hydraulically actuated wire bending machine - has rotating cam actuating master cylinder which drives slave cylinder to oscillate wire bending slide
Inventor: LANGE GERHARD
IPC: B21F1/00
Filed: 1977-05-06
Abstract: The hydraulic wire bending machine has a rotating cam which imparts an oscillating motion to a lever. The end of the lever is connected by a pin to the rod of the piston which operates in the master cylinder.
