Title: Machine for exposing joints of preserves tins for inspection - has guided cutter for splitting joint of rotating and clamped tin
Inventor: ADAMSON ALAN
IPC: B67B7/72
Filed: 1975-10-09
Abstract: The machine for cutting up of the sealed end joints of tins is used as an inspection machine for controlling the efficiency of the sealing. This machine can be used in the factory where tins are filled and also in the factory making these tins. The tin which is clamped at its base and held at the top by a guiding tool is rotated and the rotating cutting disc (118) at the end of its shank is swung along the guide edge (120). The cutting tool is guided so that it shears the tin joint top edge at an angle thus separating a continuous rim and exposing the whole folded joint to inspection. The cutting disc is able to follow the guide because it floats on its shank under spring (124) force.

Title: Antigens and antibodies simultaneous radioimmunological determination - using antigen-coated particles
Inventor: UTHEMANN HORST DIPL CHEM DR
IPC: G01N33/543
Filed: 1976-05-22
Abstract: In the parent patent a sample of an unknown serum is brought into contact with the walls of a container having a coating with a known antigen content. After incubation, removal by suction and washing, a radioactively labelled highly-pure antigen is added and again incubated. After removing by suction and washing, the radioactivity of the coated part of the container is measured in a gamma-radiation appts. To simultaneously detect antigents with >=1 binding site or their antibodies with >=2 binding sites in the molecule, the serum sample is firstly incubated with a known amt. of antibody and the resulting mixt. is brought into contact with walls of the antigen-coated container. The improvement comprises using any solid body with coated surfaces instead of a container with coated walls. The procedure can be used for the simultaneous detection of e.g. HBs antigen and anti-HBs. Coated particles (e.g. coated headlets) are simpler to use than coated containers.

Title: Hydraulic binders mfr. in cyclone slag tap furnace - where the raw materials may include ash obtd. from power stations
Inventor: KAYATZ KARL-HEINZ
IPC: C04B7/14
Filed: 1976-10-29
Abstract: In the mfr. of hydraulic binders, melting is employed to combine raw materials, contg. lime, clays and silicates used in stoichiometric amts. The materials are fed separately or simultaneously, together with solid fuel, which pref. has a high ash content, to a burner in a cyclone slag tap melting furnace. The liq. slag is drawn out of the furnace and granulated by rapid cooling; and the waste heat is used in a conventional way for steam generation. Used for mfr. of binders such as Portland cement. The process permits the exploitation of the large amt. of ash obtd. from thermal power stations, with optimum use of heat, using cyclone furnaces of conventional type. The tangential feeding of air for combustion and solid fuel, e.g. coal dust, into the furnace has proved most advantageous. The raw materials contain SiO2, Al2O3, Fe2O3, CaO, MgO, SO3, and the ash which will arise from the fuel is analysed so its compsn. is considered when calculating the stoichiometric amts. of raw material required. The materials, fuel and air are burned in the furnace. The molten slag tapped from the furnace is quenched in a conventional manner using air or water to obtain a granulate ready for use.

Title: Trimming potato chips after rejection for surface cleanliness - by mechanically shearing off the tip of each end before reinspection (NL 1.5.77)
IPC: A23L19/12
Filed: 1976-11-05
Abstract: After inspection for surface cleanliness, potato chips cut from peeled and boiled or streamed potatoes are sorted; and those rejected for shortcomings have the tip of each end sheared off mechanically. An electronic re-inspection is then carried out. The equipment for shearing off the ends comprises two dishes side by side, one slightly overlapping the other. The vertical rims of the dishes have a gap inplaces and each dish has a number of carriers which divide it into compartments. The carriers are rotated, and at a gap in each dish rim, a knife is arranged. The chip thus cut off at one end, is ejected by centrifugal force from the first dish to the second where its other end is cut off. The chips are produced with the min. of waste. The chip is trimmed mechanically at both ends and not the potato as a whole, and the cleaned chip is re-inspected.

Title: Laboratory colloid mill - having conical rotor with narrow end towards motor and outlet on the other side
Inventor: GRIESER BERTOLD
IPC: B02C2/10
Filed: 1976-12-07
Abstract: Colloid mill has a conical shaped rotor mounted on the shaft of the drive motor and rotating in a conical stator. The outlet is on the side of greater dia. The housing which encloses the mill has a direct opening for the shaft. The rotor on the motor shaft has its lesser dia. directed towards the motor, the outlet being on the other side. The rotor has an extension which projects down the shaft to the gap through the housing. Here it contacts a seal mounted in the housing. Feed is fed from the hopper above into an annular feed space around this extension. From here it passes into the milling space. Since the shaft passes through the housing on the narrow end of the rotor, pressure on the seal is relatively low and the arrangement is not complicated. This reduces wear on the seal.
