Title: Corrugated cardboard - is coated on its inner faces with polymeric material to increase stiffness
Inventor: ARIAN CHARLES MOURAD
IPC: D21H17/57
Filed: 1972-10-11
Abstract: A stack of corrugated cardboard panels, each having a corrugated core between plane facing sheets is advanced on a conveyor with the channels of the panels vertical, and the sides of the stack are pressed together by pref. upper and lower pairs of endless belts travelling along guide rolls to maintain adjacent panels firmly together. Pref. the upper pair of endless belts define with the top face of the stack a trough into which coating material (e.g. solution or emulsion of urea formaldehyde, acrylic, styrene or polyurethane resin and paraffin wax in a carrier fluid consisting of a mixture of water and alcohol, ethanol or methanol) is run.

Pref. hot air is subsequently blown through the channels to cure the coating material. The panels have improved rigidity when wet. There is no coating material on the other faces of the panels which may damage subsequent processing machines.

Title: Blast furnace pig iron prodn process - comprising injection of oxygen and additional fuel through tuyeres at two levels
Inventor: FINK FERDINAND DR
IPC: C21B5/06
Filed: 1972-12-16
Abstract: Pig iron prodn. from iron ore and conventional fuels is carried out in blast furnaces fitted with tuyeres fitted at conventional level and additionally at bosh level. The gas blown into the furnace is a mixture of circulating gas obtd. from gas given off at the furnace top enriched by O2 mixed-in at the tuyeres. The gas compsn. at the lower level tuyeres is adjusted to maintain the blast furnace at >1050 degrees C at the relevant zone whilst the higher level tuyere gas mixt. is adjusted to form together with the furnace upstream gas a mixt. which suppresses any excess reduction gas required for direct reduction and only provides sufficient gas for the operation of the furnace in the relevant zone at 1050 degrees C. Part of the coke in the charge may be replaced by solid or liq. fuels mixed with the tuyere gases. The process improves the thermal efficiency of pig iron prodn. saves expensive coke and permits easy control of furnace conditions.

The second material layer may be a normal semiconductor of opposite conductivity. The second material layer may be a normal semiconductor of opposite conductivity. If the second material is a metal, the first layer is formed by a doped, magnetic, semi-insulating semiconductor. The two layers may be reversed and the semi-insulating semiconductor may be also combined with a normal semiconductor at opposite conductivity.

Title: Nondestructive electromagnetic material testing - uses magnetisation change in a specimen to generate in it a voltage collected by contacts
Inventor: LAMBECK MARTIN PROF DR ING
IPC: G01N27/82
Filed: 1973-08-17
Abstract: Two or more contacts are provided on the specimen surface, and the collected voltage is applied to a meter. The contacts are wiper or roller contacts movable on the specimen surface. A current carrying coil reverses magnetisation in individual, strictly limited specimen areas. The coil can move relatively to the specimen. The voltages collected from the above contacts give information concerning mechanical stresses, magnetic or mechanical properties and their distribution in the specimen. Voltages are displayed on an oscilloscope, and possibly compared with those of a standard sample.
Patent DE-2343266-A1 (DE)
Title: Chain with two types of link shapes and materials - provides extra elasticity and wear resistance
Inventor: ESSER PAUL
IPC: F16G13/00
Filed: 1973-08-28
Abstract: To produce a chain of increased elasticity, the even number of links are of circular form, whilst the odd number of links are of conventional longitudinal form. When the chain is loaded, the circular links are subjected to a bending stress which results in an elongation of the links, hence the extra flexibility. The same result is achieved by the use of links of different material instead of different form. The overall elasticity of the chain can thus be selected since it is dependent on the number of elastic links it contains. When manufactured on a machine, one link type can be pre-produced and magazine fed into the assembly line.

IPC: F16K5/06
Filed: 1973-09-12
Abstract: The valve body defines, together with the casing, a space which, in the closed position, is connected with the port (slot) of the valve body. This space is filled with a sealing cpd. which seals the port of the valve body in the closed position. Prevents heat-setting casting resign from reaching the hollow space of the valve and thereby impairing the functioning of the valve. The sealing cpd. may be an elastified epoxy resin. The space is provided with apertures for the passage of the originally liquid, but solidifiable, sealing cpd. which may have rubber-elastic, damping, characteristics.
Patent DE-2346703-A1 (DE)
Title: Installation for trimming and straightening of panel radiator - uses roller conveyor to move radiator to machining stations
IPC: B21D19/00
Filed: 1973-09-17
Abstract: After welding together the two panels, the radiator edges have to be trimmed, straightened and freed from all burrs and sharp corners. This is done by placing the radiator on a roller conveyor which moves it past cutting and straightening rollers and Vee-shaped grinding wheels which are located on either side of the conveyor. To trim the leading and the trailing edge of the radiator, clamps hold it on the conveyor at such a position where cross slides with the necessary tools attached to it, carry out the required operations. To accommodate radiators of varying sizes, the conveyor width is adjustable.

Title: Reinforced firebrick spiral for building into chimney - with attached fan, for energy saving by regulation of flue gases
Inventor: KONVALIN GEORG
IPC: F23L17/00
Filed: 1973-12-15
Abstract: Reinforced firebrick spiral with a regulator (fan) is built into a chimney. The fan is at the end of the spiral as required, deciding the length of the spiral, and also built in inbetween. The size and length of the spiral depend on the chimney pipe; the components are 0.5-2.0 m long. The fan is mounted on a fireclay cone, and can be set in the spiral. This decides the length and dia. of the chimney. In a factory chimney, operation of the fan depends on the thermal loading. The fan can be 2- or 3-bladed. The spiral is mounted and fastened at the chimney head, with rust-protected materials. The whole forms a modular system, for a small house chimney to a large factory chimney. Regulation of the flue gases results in saving of energy.

Title: Rope winch drum for hoist - has body enclosed in grooved sleeve of rustproof material
Inventor: SCHWARZ WILHELM DR ING
IPC: B66D1/30
Filed: 1974-05-25
Abstract: The drum is particularly for the hoist mechanism of a nuclear reactor loading machine, and its body (1) is enclosed in a sleeve (9) with rope grooves (14) and of corrosion-resistant material e.g. plastic. The sleeve can be shrunk onto the body and also secured to it by a bush (15) accommodating a rope clamping screw (19). There can be flanges (10, 11), on the sleeve ends, fitting over rims (2, 12) on the body. The advantage is that there is no need to use non-rusting material for the drum to resist water picked up by the rope from the reactor basin, and material and machining costs are thus greatly reduced.

Title: Vehicle plastic moulded dashboard - with prefabricated panels to secure covering skin and reinforce mould
Inventor: JANZ JOACHIM
IPC: B60K37/00
Filed: 1974-08-09
Abstract: The outside of the moulded dashboard is fitted with a plastic skin (2), stretched into the mould prior to the plastic foam etc. Being applied. The edges of the skin are tensioned using a special moulded, prefabricated panel (5) with lipped edges. The lipped edges grip the edges of the skin and hold it securely during the fabrication. This prevents fold from being formed in the plastic skin. Also it prevents weakened thin sections in the plastic, especially if deep plastic forms such as glove pockets are being moulded. The prefabricated plastic insert can be made to fit either way round.
