Patent GB-2091874-A (GB)
Title: Intruder detection system
IPC: G08B13/12
Filed: 1982-01-18
Abstract: Light pulses are fed from a source (4) to a detector (5) via a transmitting optical fibre (2), an optical terminator (6) and a receiving optical fibre (3), both fibres being either stepped index fibres or poor quality graded index fibres. The fibres are disposed in intimate contact within a cable (1), and compression of the cable causes microbending and permits light pulses to breakthrough from one fibre to the other. The time interval between arrival at the detector of a light pulse after passage through the total length of the transmitting fibre and the receiving fibre, and arrival of a breakthrough pulse is indicative of the location of the compression. The cable may be laid around the perimeter of a site to be guarded so that compression will occur when an intruder crosses the cable. The system is not susceptible to interference and infra-red light pulses may be used to make the system totally covert. In addition to location, indication can be obtained at the detector of the type of intruder or of multiple intrusion. <IMAGE>

Title: Method of and apparatus for dressing coal slurry
IPC: B03D1/14
Filed: 1982-03-09
Abstract: A method is proposed for processing high-ash coal sludges by flotation of a slurry in the cells of flotation units, particularly for processing gas coal and open burning coal which are difficult to float, in which the coal slurry to be processed flows through the cells of the flotation unit pre-conditioned and controllably, particularly with control of the dwell time. In a preferred embodiment, the control of the dwell time occurs by a controlled distribution of the slurry to cells of the flotation unit which operate in parallel. For the purpose of controlling the dwell time of the slurry in a flotation unit, cells which are traversed in parallel are additionally connected or disconnected as a function of operating parameters, such as slurry density or solids content or solids distribution.

Title: Apparatus for scrubbing dust particles from the offgases of a nuclear facility
Inventor: VERACHTERT WILLY
IPC: G21F9/02
Filed: 1983-02-17
Abstract: To scrub dust particles from the offgas of a nuclear facility, especially from the offgas of a vitrification furnace for highly radioactive waste, a vertically standing counterflow scrubber 6 is used under which a collecting vessel 1 for the scrubbing liquid is arranged. The scrubbing liquid is conducted through a circulatory system to minimize secondary waste. In order to substantially increase the period of time in which the scrubbing liquid can be utilized, the collecting vessel 1 has two partition walls 2, 3 which are arranged so as to be laterally spaced from each other and which extend transversely through the collecting vessel and have a height less than that of the collecting vessel. In this connection, the partition wall 3 adjacent the inlet 10 for the scrubbing liquid is fixedly mounted to the cover of the vessel and the partition wall 2 disposed beyond the first partition wall in the direction of flow is fixedly mounted to the floor of the vessel. The ends of the two partition walls mutually overlap. The drain 9 of the scrubbing liquid from the collecting vessel is arranged behind the lower partition wall. In this manner, the contaminated scrubbing liquid is subjected to a cleansing by means of sedimentation and decantation before recycle to the scrubber at 8 via pipe 11 by means of airlift 12. Contaminated gas enters at 14 and exits at 7; settled sediment is removed via pipe 13. <IMAGE>
