Title: Hand operated overhead working platform - winding gear inside cage, guide rollers steady descent, cage carries hooked arms for safety
IPC: E04G1/20
Filed: 1974-02-18
Abstract: A hand operated overhead working platform has a wheeled trolley with uprights between which the cage travels, a hand operated winging gear incorporating a worm drive and ratchet mechanism being attached to one end of the cage, so that the cage is lifted by cables passing over guide pulleys attached to the trolley uprights, one strand of the lifting cable running horizontally underneath the cage.

Title: Mechanically solid pellets of iron oxide - pellets dried before roasting treble prodn. of shaft furnace and save fuel
IPC: C22B1/16
Filed: 1974-04-12
Abstract: Green pellets of metal oxides, (esp. of Fe, Mn, Cr) are dried in special equipment at 150-300 degrees C to a max. moisture content of 1.5% before being roasted in a shaft-furnace at 1000-1500 degrees C. Due to their high green strength, the pellets do not burst when they enter the shaft-furnace and prodn. can be at least doubled. The process is primarily for pellet prodn. from finely-divided ores or concentrates but is also suitable for waste materials. A magnetic concentrate, milled to grain size 10,000 cm2/cm3, and 99% of which would go through a 200 mesh sieve, was mixed with 2% sulphite lye and water and made into pellets contg. 6% moisture. The crushing strength was 1 kg./pellet. These pellets were dried in special equipment to a moisture content of 0.2%, then fed to the top of the sintering shaft and gradually heated to 1200 degrees C. The burnt pellets had an average crushing strength of 105 kg. and an abrasive strength of 83%. Alternatively, 1% sulphite lye and 0.5% bentonite can be used as the binder. In both cases, prodn. was trebled and fuel consumption was 9 kg. oil/tonne of pellets compared with the normal 15 kg./tonne.

Title: Friction torque transmission between coaxial shafts - avoids flanges and wedges and pref has epoxy resin bond
IPC: F16D1/05
Filed: 1974-05-10
Abstract: A coupling for transmitting torque between coaxial shafts having conical end regions comprises a sleeve encasing both end regions, a locking mechanism preventing the shafts from moving axially apart and a friction coupling transmitting the torque between the two conical end portions; this friction coupling can be so adjusted by fluid pressure as to exert a sufficiently high pressure upon the conical portions contd. within it and against the sleeve surrounding it to enable the full torque to be transmitted by friction. Pref., the outer sleeve is bonded to the conical end portions of the shafts by the injection of a setting matl., esp. epoxy resin contg. silicon carbide powder, onto the intervening conical spaces. Alternatively, the space between the conical shaft ends and the outer sleeve is occupied by two separate cast iron tapering sleeves forced apart and onto the conical ends of the shafts by injection of fluid into an annular duct placed between them generally along the line of the joint.

Title: Hydro cracking of feeds contg. nitrogen - with prior hydro denitrification and high ppressure prefactionation of effluent
Inventor: REITZ ORTWIN
IPC: C10G47/00
Filed: 1975-05-21
Abstract: Petroleum hydrocarbon feeds contaminated with N cpds. are hydrocracked by (a) contacting the feed with H2 in the presence of a hydrodesulphurisation, hydrodenitrification or hydrocracking catalyst in a first reactor at 300-550 degrees C (pref. 300-470 degrees C) and 15-250) atm; (b) passing the effluent to a 1st separator at the same pressure and a temp. of 200-300 degrees C (pref. 250-290 degrees C) to obtain an NH3-redn. rich vapour fraction and a liq. effluent contg. 50 ppm NH3; (c) mixing the liq. effluent with at least part of the bottom product from a subsequent prefractionator; (d) passing the mixt. to a 2nd reactor, where it is treated at 300-550 degrees C (pref. 300-440 degrees C) and 15-250 (pref. 50-250) atm; (e) mixing the effluent from the 2nd reactor with the vapour fraction from the 1st reactor; (f) passing the mixt. to a prefractionator at the same press. as in the 2nd reactor, and stripping it with a gas (pref. H2) to obtain a vapour overhead (H2 + products) and a heavy bottom product (heavy products + unconverted feed); (g) recycling at least part of the bottoms to step (c); and (h) cooling the vapour overhead, separating an H2-rich gas, and fractionating the liq. phase to isolate the required products. Since the NH3 formed in the 1st reactor by-passes the 2nd reactor, the latter can be operated with a conventional NH3-sensitive hydrocracking catalyst. The heavy bottom product from the prefractionator is recycled at the same pressure as that in the 2nd reactor, thus reducing energy consumption.
