Title: Support roll for rotating drums, esp. rotary drum furnaces - where roll can tilt to ensure uniform contact with running rings on periphery of drum
Inventor: JACOB WERNER
IPC: F27D99/00
Filed: 1979-01-25
Abstract: Drum is fitted with a row of running rings, each of which rests on two support rolls. Each roll consists of an outer ring mounted via a row of bearings on a hub aligned on a shaft located between a pair of bearing blocks. The hub contains a pair of bearings for a swivel shaft located at 90 degrees to the shaft carrying the roll. The overall result is that each support roll can tilt axially to correspond with the surface of the running rings, so line contact is maintained at all times between the rings and the rolls. With large drum furnaces, the load on each support roll can reach 1000 Mp; it is thus very important to ensure that the load created by the drum is evenly distributed between all the rolls, and that each roll is uniformly loaded. The invention achieves this objective.

Title: Data communication between stations over unidirectional loop - uses optical fibre links between adjacent stations connected together by ring main
Inventor: LENTZE FELIX DIPL ING
IPC: H04B10/275
Filed: 1979-02-15
Abstract: A number of stations (1, 2, 3) communicate with each other over optical fibre links. The links are connected together to form a complete loop and information passes round it in one direction only. At each station, the incoming fibre is terminated by an optoelectronic transducer and amplifier and the outgoing fibre (5) is driven by another. The two transducers are normally connected together by a switching circuit. Each station monitors all the communications passing round the loop and intercepts those addressed to it. When a station wishes to send messages, it operates its switching circuit to break the loop and connect the outgoing fibre to its own transmitter. The transducers are amplifiers all receive their power supplies from a ring main (4) running in the same conduit as the optical fibre and fed at one of the stations.

Title: Carbon recycling combined with nuclear energy distribution - to convert carbon di:oxide from flue gases to fuel, e.g. methanol
Inventor: HEIMANN GEORG DR
IPC: C01B32/40
Filed: 1979-07-09
Abstract: C is recycled from CO2-contg. flue gases by quantitative and selective CO2-removal from the flue gases, e.g. of a power station, and chemically bonding to a solid or liq. form suitable for transport. The process is combined with CO2 conversion into C-contg. prods. having a high energy content, e.g. combustion engine fuel, by a series of energy-absorbing processes using the thermal- and/or electrical energy of a nuclear reactor. The prods. are divided into small quantities so that the energy taken up from ththe nuclear reactor can be stored and divided into small quantities. The process can be used in Fe smelting, to heat the ore to reaction temps. and reduce the ore with the CO recovered. CO or MeOH can also be used in the chemical industry, e.g. for plastics, whereby crude oil consumption can be reduced.

Title: Production of textured surface on warp-knitted fabric - using revolving discs with thread-lifting pins to vary thread tension
Inventor: ARMENGOL RODO RAMON
IPC: D04B27/12
Filed: 1980-04-18
Abstract: A device for producing a textured effect in warp-knitted fabrics by varying the tension of the warp threads in a random manner during knitting comprises a series of closesett metallic discs on a revolving shaft, each having an eccentric pin projecting from one face of the disc. The position of the pins on neighbouring discs is randomly variable. The warp threads pass between the discs, those threads corresp. in position to the pins on the discs being alternately raised and lowered as the shaft rotates, giving variations in thread tension which produce intermittent variations in the surface character of the knitted fabric. The device is simple and reliable, and can be added to existing machines without difficulty. IT gives warp-knitted fabris a novel appearance, with random textured patterns of great variability, which can be simply altered in length, intensity and distribution.
