Title: Foundry facing and backing sands for moulds and cores - with continuous reclamation and sepn. of fine and coarse sands
Inventor: STEINHEIDER WINFRIED
IPC: B22C1/00
Filed: 1973-04-26
Abstract: The facing sand (F1) is chromite or zircon sand with a binder (e.g. furane resin) and a gas-former (e.g. polystyrene foam) and a layer of 10-150 mm (pref. 20-80mm) is used. The backing sand is quartz gravel, size 1-20 mm (pref. 2-5 mm) with low binder content. After casting, the used moulds and cores are vibrated on a grate from which the sands go to a crusher with min. gap 20mm so the coarse sands is not crushed; the crushed sand is then blown to the top of a multicyclone cascade screen separator. Coarse lumps on the first screen go back to the crusher and the sand retained on the second screen goes voa another cascade to a bunker for re-use in the backing-sand mixer. The fine sand goes down the first cascade where it is sepd. from the binder due to the difference in density and, on reaching the bottom is fed to a bunker feeding the facing sand mixer. The fine dust removed in the separator is binder residue and can be burned.

Title: Fabricating thermoplastic layflat film - in two layers oriented at right angles
Inventor: SUDO MICHIO
IPC: B29C48/21
Filed: 1973-02-24
Abstract: In a process for fabricating a laminated cylindrical film with a plastic resin base, the laminated structure consists of three layers, the inner layer being stretch oriented transversely and the outer layer being stretch oriented longitudinally. The median layer is formed from a film having a lower fusion point than the inner and outer layers, and consolidation is brought about by heating to a temp. slightly below the fusion point of the median layer so that it is bonded to the other two layers. The three layers may be extruded from annular concentric orifices, and orientation in perpendicular directions gives greater strength and enables thinner films to be used for a given weight. The three films are extruded from concentric orifices. The outer layer is then stretched longitudinally between two sets of rolls while the inner film is expanded by a rotating mandrel, the film being then cooled rapidly and flattened. The outer and inner layers may be of a high m.pt. polyolefin while the median film may be of e.g. ethylene/vinyl acetate or ethylene/acrylonitrile copolymers.

Title: Prepn of azo pigments in organic solvents - by diazotising amines with nitrite salts in presence of sulphonic or carboxylic acids
Inventor: LANDLER JOSEF
IPC: C09B29/00
Filed: 1974-10-15
Abstract: Azo pigments are made by diazotisation of aromatic amines without water-solubilising gps. in non-aq. organic solvents using nitrite salts, in presence of mono- or polysulphonic or carboxylic acids, and subsequently qeacting with a coupling component. Compared with diazotisation with nitrosyl sulphuric acid, effluent contamination is reduced, since little or no excess acid is present. Time and cooling energy needed to dissolve nitrosyl sulphuric acid in aprotonic solvents and neutralisation or excess H2SO4 are eliminated. Use of almost exclusively solid reagents permits a simpler and safer process. The pigment obtained have high purity, soft grain, narrow particle size distribution, excellent dispersibility in plastics and paints, high gloss and excellent covering power in paints.

Filed: 1975-10-21
Abstract: A bridge circuit which is connected between the network conductors is used in the monitoring device. One of the bridge arms is connected to earth through auxiliary resistors (R1, R2) and the other bridge arm is connected to earth through the insulation resistances (Rp, Rn) of the network conductors (P, N). A monitoring circuit (R3, OE1, OE2) in the bridge null-point branch (10, 12) trips in the event of asymmetry of the insulation resistances (Rp, Rn). In order to avoid the cost of floating evaluation circuits, the monitoring circuit contains at least one coupling element (OE1, OA1 or OE2, OA2) for non-electrical signal transmission. The coupling element, or each coupling element, contains an input element (OE1 or OE2) whose output signal corresponds to the current in the null-point branch of the bridge, and an output element (OA1 or OA2) which detects this output signal and converts it into a display or response signal. <IMAGE>
